Connecting the telephone wire to the socket. How to connect a telephone socket: connection diagram and installation rules

Connecting a device such as a telephone socket (connector), at first glance, is not difficult. The electrical voltage supplied to it is safe for humans. Therefore, it seems that everything can be done without disconnecting from the current source. However, when making wire connections, it should be borne in mind that if someone calls during operation, you can get an electric shock. The voltage during a call rises to 120 volts, and this value is already palpably on the fingers.

In fact, for a person unfamiliar with the design features of the phone and wiring diagram, to collect the entire line will not be so easy. However, nothing is impossible. It is enough to at least theoretically imagine how to connect the wires, and then all the work will take no more than half an hour.

There can be as many connectors for connecting a cable and a telephone in an apartment. All detachable devices are connected in parallel, and only two wires are used in the line. If your communication device does not work after installation, just swap the wiring. And now we will understand in more detail.

We are all used to the fact that the wires in our apartments in their mass are attached to the wall in its lower part. In new houses, all communications are hidden inside the wall, and various cables can also be hidden inside the baseboard. When wiring hidden in the wall, then for laying the cable a groove is made to the installation site of the socket connector. In all cases, a set of the following measures is carried out:

1. With the help of a grinder, a channel is cut into which the wire is laid. In order for the wires to stay in the groove, they are reinforced there with plaster. After the gypsum has dried, the groove is plastered and puttied.
2. The second option for fixing the cable in the channel is to use plastic brackets that press the wiring against the wall. This method involves an open mount, but it can also be used with a large number of wiring lines inside the channel.
3. Mounting under the baseboard is quite simple if you have plastic baseboards with special grooves. Wooden plinths will have to be made to order with milling for wires. Using an old wooden baseboard will force the chisel to gouge the groove.
4. The next step is to install and connect the laid cable to the connector. The socket connector is attached to the wall with screws through the holes in the back of the box. After that, the wiring is connected to the terminals and the box cover is closed. This method is suitable when there is an external type connector box.
5. If the box is of an internal type, then you will have to make a recess in the wall with a puncher according to the size of the socket box. The box inside the recess is connected to the wiring and fixed with a gypsum mortar. After the gypsum dries, everything around the box is carefully puttied.

Before connect wiring, they need to be checked with a tester for polarity. If the connection is not made correctly, then the equipment will not work. But this is not a reason for frustration - it will be enough just to swap the wires. All of these actions are not so difficult for a beginner. In this case, the circuit may be needed only in order to know where certain cables will pass.

Connecting to the wires of detachable devices

Exist socket connectors old and new types. The telephone, like any technology, has gone through its stages of evolution. Once the connection with the device was carried out directly. In the second half of the 20th century, they began to use the connection using sockets (connectors). Such connectors and plugs for them were designated by the letters RTSHK-4, that is, telephone plug-in connectors with four contacts. These connectors allowed two devices to be connected to them.

Now only two contacts are used in residential buildings. Such connectors are designated by letters and numbers: rj-9, rj-11, rj-12. The first of them is intended for connecting the voice tube to the device, and the latter is used in office premises, as it can use several lines. We are also interested in the second of the connectors.

You can connect the rj-11 socket connector yourself, without calling a specialist. The main thing - stick to the scheme and prepare the necessary tools for work:

• despite the fact that the telephone line is conductive, rubber gloves must be used; in this case, gloves used by electricians are not needed - just take those that are sold in hardware stores;
• in order not to confuse anything with the wires, you must have a tester with you to check the voltage;
• you will definitely need both a Phillips and a flat screwdriver;
• pliers and some kind of knife will help to remove the insulation;
• you should stock up on the required footage of a two-core cable with a cross section of 0.3 to 0.5 millimeters.

When the preparatory work is completed, we proceed to assemble the circuit of the entire line. The main work is carried out in several stages:

1. We put on gloves and begin to remove insulation in the right places. The insulation is removed carefully so that the internal conductors are not damaged. Damage to the cores can cause a breakdown and everything will have to be done again.
2. The next step is to connect the cable to the outlet. Here it is necessary to refer to the diagram, which is either in the instructions or inside the housing of the socket connector.
3. The tester checks the "plus" and "minus". If the wires are connected incorrectly, there will always be interference in the tube. The wires are fastened in special grooves and fixed with screws.
4. At the last stage, the socket housing is attached. How it is attached has already been said: either it is built into the wall, or it is attached to it.

On this, we can say that the installation of the line is completed. If there are no new problems, then everything is done correctly.

Connecting a telephone socket. Diagram for RJ connectors

Making a self-connection, buy universal socket and plug. Both old-style phones and new ones are connected to such connectors without any problems. A connector for an rj-11 connector and four pins for attaching a cable are built into the case. Everything is connected elementarily: two incoming wires (red and green) are attached to the terminals. Red insulation indicates a core with a plus sign and green insulation with a minus sign. Next to the contacts is a plastic tongue, next to which these two conductive wires are attached.

There are times when unknowingly bought socket with six pins. This standard is for RJ-25. It is not used in residential buildings and apartments, but you can still connect it. How to properly connect the telephone socket in this case, the diagram will help:

• wiring is connected to the third and fourth contacts - red and green, which are at the very top;
• cables to all sockets are always used of the same type.

Connecting the legrand telephone socket

The name comes from the company of the same name. All products of this French brand have high quality and ease of operation. Connecting the wires is easier than in all the cases described. Using legrand, it is not necessary to strip the wires from the insulation in order to connect to the contacts. Design features female connector are such that when inserting the wiring inside the clamp, the insulation cuts itself as required. With one turn of the clamp, the insulation is stripped and the stripped core is secured.

After connecting to the legrand line, it is checked with special devices. Experts advise doing this with a multimeter. Terminal voltage must not exceed 60 volts. If everything is so, then the connection was made exactly according to the scheme.

Long distance calls and international communications from a stationary telephone are much cheaper, you do not need to constantly monitor the degree of charge of the batteries and periodically change them.

Connecting one landline phone or several in parallel to a communication line with your own hands is the simplest task, almost any person who does not even know the intricacies of a connected business can do it.

What is the voltage in the telephone line

The telephone line is live direct current 40-60V if the phone is not connected or connected, but the handset is placed on the telephone set. During a call, the voltage in the communication line becomes variable with an amplitude of up to 120V. When you pick up the handset, the voltage drops to 6-12V. This tension is not life-threatening, but it can cause discomfort. It is impossible to disable the communication line or damage the telephone set during connection. The maximum that can happen is a disconnection of the telephone line for a few minutes, if the handset is picked up for a long time without dialing, or the conductors of the communication line are short-circuited. This automatically disconnects the telephone line from the automatic telephone exchange (PBX) to save energy in the event of a short circuit between the conductors of the communication line or an unhooked handset. So you can safely proceed to self-connection telephone to the communication line.

Before connecting a landline phone to the communication line, it is desirable, but not necessary, to check that the communication line is ready. The voltage in the line can be measured with a voltmeter designed to measure direct voltage. How to measure constant pressure pointer tester and multimeter, described in detail in the article Voltage measurement. If the phone is not connected to the line or is connected, but the handset is placed on the phone, the device should show a voltage of 40-60V. If there is no voltmeter, you can check using potatoes, and this is not a joke, but a real way to check. It is enough to stick the noodle wires stripped of insulation into the cut of the potato. Batteries are not needed, as the wires are already energized.

Scheme of connecting a wired landline telephone to a PBX

From the automatic telephone exchange (ATS) to each house, a hundred-pair telephone cable is stretched, which branches out with ten pair cables along the entrances of the house. The ends of ten paired cables are soldered into ten paired plinths in the entrances of the house. Plinths are installed in boxes or fixed on the walls. The photo shows a plinth with an open lid.

Previously, skirting boards were made of duralumin, now they are made of plastic. In modern plinths, line wires of communication lines are connected by pressing into combs with a special tool. From one of the pairs of plinths to your apartment, a communication line is stretched with a TRP telephone wire, which signalmen call noodles. At the end of this wire, an RTSHK-4 (old-style) socket is installed in the apartment, or a modern RJ-11 socket, and a wired telephone is connected to it using a plug.

As you can see, the scheme for connecting a wired landline telephone is simple, an individual pair of wires is stretched from the PBX to your apartment, through which communication is carried out. As can be seen from the diagram, the plug and socket are needed solely for ease of use and do not take part in the operation of the phone. You can connect the telephone wires coming from the plinth to the telephone cord, and the telephone will work successfully.

How to connect the phone to the communication line

Connection of telephone sets to the line is carried out by means of a detachable connection - plugs and sockets. At present, telephone connectors of two standards are used in operation. Obsolete Soviet ones that meet the requirements of GOST 8810-81 (CT SEV 5396-85), which was valid until 01.01.92 (RTSHK-4), and modern telephone plugs and RJ-11 sockets that comply international standard IEC 60669-1 and 60884-1 (623K). Universal telephone plugs and sockets are also used, which make it possible to connect plugs and sockets, released according to the new and old standard among themselves.

The question seems not relevant, but there are still many phones in operation that have been connected for a long time and this information may be required when repairing the connector on your own or transferring the phone.

Of course, the Soviet telephone jack is bulky, does not correspond to modern aesthetic views, but it is reliable and for a long time successfully performed, and continues to perform the functions assigned to it.

The telephone socket has four pins for connecting the plug and two for switching the capacitor. The positioning of the plug during insertion is ensured by the holes in the socket cover. The telephone socket has four pins for connecting the plug and two for switching the capacitor. The positioning of the plug during insertion is ensured by the holes in the socket cover. The line is connected with a screw connection to the two right-hand contacts. To control the integrity of the line, a capacitor was also installed in the outlet, which was connected to the upper right contact and the lower left one. When the plug was inserted into the socket, it broke the circuit with a wedge-shaped pin and the capacitor turned off. When it was necessary to check the line, it was enough to remove the socket and the signalmen from the exchange could, by applying alternating voltage to the pair, check the condition of the line, and thus determine whether the line or the telephone was to blame for the lack of communication. When two phones are connected in parallel and the plug of one of them is removed, the line sits heavily, since the alternating voltage passes well through the capacitor. If you accidentally forget such a socket connected to the telephone line, then be sure to disconnect it from the line or remove the capacitor. It is desirable to remove it from all connected telephone sockets, since in modern telephone communication lines the capacitor does not participate and is not needed.

The telephone plug is a plastic box of two halves, one of which has four flat contacts inserted. A cord coming from the phone is connected to them with screws. The photo clearly shows which contacts to connect it to. It does not matter which contacts the wires are connected to for the phone to work, the main thing is that the contacts of the telephone socket, to which the line wires come, are connected to the plug contacts, to which the wires come from the phone. The wedge-shaped pin is used to disconnect the test capacitor from the communication line.

With the advent of foreign-made phones in everyday life, in which the cord ended with a RJ-11 6P4C plug, and the sockets were all installed with RTSHK-4, adapters (adapters) immediately appeared on sale, allowing any owner of the novelty to connect the phone to the line without outside help.

In the adapter, the two upper flat pins were connected to RJ-11 pins 3 and 4 (standard crimping scheme), in the photo on the left, and the lower flat pins were connected to RJ-11 pins 2 and 5, in the photo at the bottom of the adapter.

Connecting a telephone to a universal socket RTSHK-4 623K RJ-11

Another creation of the transitional period, a universal socket, a symbiosis of RTSHK-4 and RJ-11 sockets. I don’t know why they were released, but it can be assumed that when replacing the worn-out RTSHK-4, it was possible to replace them with a universal one. Thus, to provide the ability to connect phones with plugs of any standards.

Pins 3 and 4 of both RJ-11 telephone sockets are connected in parallel with the right RTSHK-4 ( standard connection), and pins 2 and 5 of the telephone socket are parallel to the left RTSHK-4.

Connecting a telephone to a 623K RJ-11 6P4C socket

Modern sockets for connecting telephones under the RJ-11 4P4C plug are small-sized, available in different body colors for all applications, wall-mounted and for internal wiring. Combined, for simultaneous connection of telephones to the communication line and computers to local networks and the Internet with RJ-45 plugs.

In the socket shown, the line wires of the telephone line must be connected to green and red wires that are connected to 3 and 4 pins of the RJ-11 4P4C socket. The polarity of the phone connection does not matter.

Connecting a fixed telephone with a handset to the line is carried out with a telephone line cord with RJ-11 6P4C plugs at the ends. RJ-11 6P4C plugs are similar in appearance to RJ-11 4P4C but have six pins. Of these, only two medium ones are used to connect the phone. Other contacts are often absent. Six contacts are used when two fixed telephones are connected in parallel according to the director-secretary system. This is when when you pick up the handset of one of the phones, the second one automatically turns off.

According to the standard for connecting a telephone, a wire of a certain color marking must be suitable for each contact number. This is designed for ease of repair and maintenance. It doesn't matter what color the wire is connected to. The main thing is that the wires coming from the PBX should be connected to the two middle pins 3 and 4 of the telephone plug.

The polarity of the connection for a landline phone that is not connected in a paired circuit does not matter.

Parallel connection of phones

Sometimes, for convenience, it is required to connect another ordinary telephone or several in parallel to an already connected telephone set to the line. Such a connection is made by simply connecting sockets in parallel, in the same way that electrical sockets are connected to electrical wiring. The polarity of the wires does not matter. Modern phones load the telephone line very little and you can connect at least 10 phones in parallel. The disadvantages of such a connection include the lack of confidentiality during a conversation. That is, during your conversation, whoever picks up the phone on any phone connected in parallel can hear your conversation. There are blocker schemes that allow, when you pick up the handset on one of the phones, to block all other telephones.

After connecting several telephones in parallel, a situation may arise when a ringing signal comes in, only one telephone rings, and all the others only emit a short, soft sound. The reason for this is the presence of the AON system ( automatic detection number) on the ringing phone, configured to detect the caller's phone number before going off-hook. Thus, caller ID immediately automatically picks up the phone and already generates a ringing signal. For this reason, all other phones connected in parallel do not ring. Usually, in modern phones, you can turn on the caller ID function to determine the number after you pick up the handset. Then, when a ringing signal is received, all phones will ring. Caller ID turned on in the caller identification mode before picking up the handset is also bad for long-distance callers, because even if you are not at home and a call comes in, even without picking up the handset, the countdown of the long-distance connection time will start and payment will be charged. But there is also a plus, if phones without AON are installed in places of rest, and with AON in another room, then a night call will not disturb you.

There are also ready-made solutions in the form of a telephone set with several radio handsets, which allow not only blocking, but also switching the caller from a lifted handset to any other. However, such phones are not affordable for everyone and have a significant drawback. During a power outage, they do not work and batteries are installed in the handsets, which serve for several years and then are replaced with new ones, at a cost comparable to the cost of an ordinary push-button telephone. Therefore, to ensure uninterrupted communication, you still need to keep an ordinary phone in reserve.

Connecting a telephone cord to a line by twisting wires

In life, there are situations when you need to connect the phone to the line, but there is no outlet. In this case, you can connect the wires with a twist without degrading the quality of communication. Such a connection is even more reliable than a detachable one. The only drawback is that you have to cut the wire if you need to connect another one. And even then, in modern phones, cords with telephone sets are connected with RJ11 plugs and it is always easy to disconnect it from the line in the case of, for example, repairing the phone. I have one phone connected in this way, while the entire cord is hidden behind the door trim, only a 15 cm long piece with an RJ11 plug at the end, which is immediately inserted into the phone socket, comes out.

The telephone cord is very flexible, it is a special wire with strands made using a special technology. A very thin copper ribbon is wound around a cotton thread. Such a conductor is called tinsel. Tinsel wires are widely used in the production of headphones, connecting handsets to bases, that is, in cases where the wires are constantly bent during operation.

There are several conductors of tinsel in each vein, and they are still twisted among themselves. Soldering tinsel is very difficult, and the mechanical strength of such soldering is low. To obtain a reliable and mechanically strong twist connection, it must be performed using the following technology.

First, the tinsel of the telephone cord is released from insulation for a length of 10-15mm and the conductors of the line wire for a length of 20-25mm with a shift with a knife in the manner described on the site page How to remove insulation. The thread of tinsel does not need to be removed. Then both wires are folded together, the tinsel is bent towards the conductor and the core of the linear wire is wound onto the tinsel pressed against the insulation. It is enough to make three to five turns.

In the same way, twisting is performed with the second conductor of the cord. As you can see, it's a neat connection. Cover the resulting connection with insulating tape. If you have a PVC tube of a suitable diameter, you can put a piece of it on the twisted place for insulation. The connection can also be made straight by bending the line wire 180 degrees before insulating. In this case, the mechanical strength will increase significantly.

In fact, we are mostly familiar with the mechanism for connecting a telephone jack. In fact, there is nothing difficult here. If you have basic training or even theoretical knowledge, then you can manage in half an hour, taking into account the laying of wires.

Types of telephone sockets

Are you going to connect your phone? To answer the question of how to do this, you first need to decide on the type of outlet. A few years ago, this question would not have been asked, since there was only one type - RTSHK-4. In every house where there was a telephone, just such standard devices were installed. Today, Soviet ingrained standards have been replaced by European ones - RJ11 and RJ12.

RJ11 is used in apartments and houses. It has only two wires.

RJ12 connects to four wires. It is used as a wiring office PBX with a large number of channels. If you plan to install a telephone at home, then it is better to focus on RJ11.

Methods for mounting a telephone socket

With minimal knowledge, you can connect your own telephone network in 5-10 minutes. There are two installation methods - open and closed. The open method involves installation on the surface without removing the finishing layer.

For example, if you have already completely renovated and now you need to hold the phone, then the socket is installed directly on the wallpaper or paint. Cable - the channel is hidden under the plinth. The open method of fastening can be carried out, in general, without mounting on the wall - the socket can be located on the floor.

It contains 4 screws. The two closest to the connector do not need to be touched. The wire is attached to the two remaining screws. Next, insulation is laid - the cores are attached to the clamp and pressed with screws. After that, the housing cover is closed. The work is ready.

It's important to know! All work on open installation should be carried out with gloves. It is better to use latex. There were cases of tension when they tried to call the phone. At this point, you may be electrocuted. The blow will, of course, not be fatal, but sensitive.

The hidden installation method involves laying the telephone wire before the socket is connected. In this case, the location of its location is planned.

Sometimes the wires are hidden in the wall, and the socket is taken out. Visually, this method of attachment resembles standard electrical outlets. Hidden and open mounting methods are called external and internal. In general, there are no fundamental differences between them.

Connecting an RJ11 telephone socket

Before proceeding with the installation, you should prepare a basic set of tools and materials:

Modern phone sockets are available different sizes and flowers. To connect RJ11 yourself, you need to adhere to the following scheme:

For more information on connecting a telephone socket, see the video:

What to look for when connecting a telephone socket

The RJ11 or RJ12 standard telephone socket contains 2 and 4 pins. They look like small metal forks. The cable is attached between the teeth of the fork. All devices are fixed only to two contacts. Professionals can use a crossover knife to secure, but at home normal fit kitchen. It is absolutely not necessary to spend money on a special tool if you have to connect it once or maximum twice.

The braid is removed from the cable by about 4 cm. The cores must be moved apart from each other.

Many do not buy modern RJ11 sockets, as there are components from the Soviet period. Here are some notations that you might find useful:

• RTSHK is the Soviet standard. Now such devices are no longer produced, but the telephone can still function today with their help. They have 4 pins and a key;
• KSPV - copper-based wire, consisting of one core. It is covered with polyethylene insulation. In most cases, such a cable is available in a standard white color. It is used for internal laying in a house or apartment;
• TRP is a distribution cable designed for laying a telephone line. This wire is single-pair, which consists of a copper core insulated with polyethylene. Has a dividing base.

How to work according to the scheme

So, most professionals work while connecting the phone according to the scheme. If you are using an old standard device, and not a European one, then it is better to buy a universal outlet. It has a modern connector and a four-pin connector. The fifth is a plastic tongue. Connecting an old type socket is similar to the option described above with an RJ11 or RJ12 connection. Two wiring wires are connected to the contacts located near the plastic tab.

It's important to know! Before connecting the socket, make sure that the plug suitable for the appliance has the wires inserted into mirror reflection to the same contacts as in the socket.

In addition to the listed RJ11 and RJ12 standards, there is also the RJ25 standard. It has six contacts. Such sockets are not installed at home, but there are situations when, out of ignorance, they are nevertheless acquired. If this happens, then the telephone will need to be connected to the third and fourth contacts, as shown in the picture:

The red and green wires are connected to these pins, so they will be easy to find. Standard cables are connected to sockets of any subtype.

As we can see, there is nothing complicated in connecting a telephone socket on your own. Good luck!

How to connect a telephone socket?

Installation of information switching on the one hand may seem easier than electrical lines. After all, they do not have a life-threatening voltage of 220/50. But installing and connecting a telephone socket is not as simple as it seems at first glance. This is due to the wide variety of stationary devices that are used in everyday life, as well as connectors, with the help of which the connection is made. Next, we will tell you how to connect a phone socket with your own hands, providing all the necessary diagrams and photo examples.

Types of connectors

Below are the types of connectors of the new sample:

Step by step installation instructions

So, how to install and connect a phone socket? First of all, you need to check the availability of the device connection diagram. From the tools you will need a screwdriver, an electric drill and the telephone socket itself.

Note: in working condition, the voltage on the line can rise to 120V. Therefore, in order to limit yourself from such unpleasant moments when installing and connecting a telephone socket to the network, it is better to use dielectric gloves.

Before proceeding with the installation, it is necessary to de-energize electrical network. Then, using side cutters or a knife, remove the insulation from the conductors. This must be done carefully so as not to damage the wires. After all, if they are damaged, they will break easily. You need to strip the cable along a length of 4 cm. Read our article on how to remove the insulation from the cable.

Using a tester, determine the polarity of the conductors. Typically, a telephone jack has a red positive conductor and a green negative conductor. But it is better to check, since it is not known how the installation and connection was carried out. If the device is not at hand, then the connection is made according to the existing plan (the diagram is attached to the device).

The next step after checking the polarity is to connect the cable cores, as shown in the photo below. After that, a telephone socket is fixed on the wall. After installation, you need to connect to the network and test installed device.

It should be noted that the body can also be of a hidden type. How to install and connect a hidden socket for the phone? First of all, it is necessary to mark the wall where the device will be installed. Using a perforator, make a hole and fix the structural elements with self-tapping screws. The installation ends with the fixing of the protective housing and testing of the fixture that has been installed.

If at home it is necessary to install and connect a socket for a telephone with 2 outputs (installation of several devices with different phone numbers), then one nuance should be taken into account - installation takes place with large quantity conductors. But in general, there are no significant differences in the work.

Wiring diagrams

The technique for determining polarity without a device has a number of advantages. She has been tested more than once. There are many options for color coding wires, and when the device is installed and connected, there is a chance of even more confusion.

The telephone socket is installed according to certain schemes. Such a scheme is developed in advance. As a rule, polarity does not really matter. But some telecommunications devices may fail or work incorrectly if this is not taken into account. The device connection diagram is provided below:

In order to simplify installation, manufacturers mark the contacts (the diagram and designation must be attached to the device). It can be in the form of numbers that are written near the contacts or on the diagram. Or the wires indicate certain color.

How the cores of twisted pair cables are correctly marked when the socket is installed and connected is indicated in the tables below:

Well, the last thing I would like to give you - helpful tips on connecting a telephone socket with your own hands. So, consider the following nuances when installing:

• To date, the most popular is the internal socket for the phone. Since it is able to harmoniously fit into any interior of the room and it is not very noticeable. But when installing it, it is necessary to take into account the fact that the wall decoration can be damaged. Yes, and spend more time.
• Buy products from trusted manufacturers. These include the companies Legrand and Vico. After all, they have already proven themselves in the modern market.
• If the numbering of contacts was not indicated on the case of the purchased device, then you need to familiarize yourself with the rules for marking wires by color. So to indicate positive contacts, green, blue and orange are used together with white. For negative contacts use the same colors, only without white.
• The old format telephone socket has a different marking standard. Therefore, if you are installing just such a device, then you need to know these rules. For example, black, orange, and green color. For minus - yellow, blue and red.

So we examined the technology of installing and connecting a telephone socket to the line. We hope the information provided has helped you complete the installation yourself!

Connecting a telephone socket

To connect a fixed telephone to the line, you need a working line from the PBX and the ability to connect a telephone to it. Phones are connected to the line using telephone jacks.

There are several standards for such sockets, they are used for different purposes: connecting one or more telephones, creating leased lines. In apartments, the RJ 11 standard socket is most often used. How can I connect the telephone socket of this standard myself?

Types of equipment

With the development of technology, telephones are improved, but in general, the principle of their operation remains unchanged. To connect them to the communication line, they still use special sockets.

In Russia, from the 80s and until recently, a single standard was used - RTSHK-4. Even earlier, the wires were connected by simply twisting them together. Now there are several standards.

The development of microprocessor technologies has led to the replacement of RTSHK-4 sockets with others - marked RJ. With their help, you can connect up to four phones to the line. The abbreviation RJ stands for Registered Jack. With this designation, there are several standards for telephone sockets:

• RJ 9 - connector that connects the handset to a fixed telephone set,
• RJ 11 - it is he who is most often used in residential buildings and apartments, the first standard adopted in the USA is also called the "euro socket", has two contacts and connects one phone,
• RJ 14 - often used in office space, has contacts and 4 wires, convenient for connecting additional lines - you can connect two phones with a separate line, it is rarely used in apartments to connect a phone,
• RJ 25 is a model with three pairs of contacts, it is difficult to connect it with your own hands, it is better to entrust such work to specialists.
• RJ 45 - a device with 4 pairs of contacts, it is used to connect computer and telephone networks or connect a telephone to a line.

There are also combined versions of RTSHK-4 and RJ 11 with both types of connectors. Such devices are used to connect computer and telephone networks. In addition, they can be used to connect devices with old and new plugs to the network.

There are also RJ 12 sockets, but they are not standard, as Legrand products are designated as RJ11 or RJ 25. TAE type devices are used to connect German and French telephone sets to the line.

Mounting methods

Telephone sockets can be mounted in an open or closed way. The open method means that all the decoration on the wall is preserved, the equipment is attached directly to the wallpaper or paint.

In this case, the wires are removed into the cable channel located in the plinth or on the wall. You can find cable channels different colors and dimensions, skirting boards with cable channels inside. Convenient models with snap-on lids. There are also skirting boards with built-in sockets. When buying them, choose those whose front panel fits well to the base, otherwise, over time, it will begin to lag behind.

Sometimes devices are mounted not on the wall, but on the floor. When connected open way You can even stick them with double sided tape.

If the connection of the telephone socket is made in a closed (hidden) way, the wires are laid in the channel before the socket is installed in the socket. Sometimes the wires are laid in the wall, and the outlet is installed outside. Most often, a copper single-core cable KPSV in a white polyethylene sheath or also a single-pair copper cable TRP is used.

Most often, telephone sockets are not mounted separately, but as part of a socket block, for example, together with an electrical socket and a switch, as in the photo.

Advice! To disguise the design, place them behind the facades of furniture or behind monitors and TVs.

Telephone jack device

The telephone socket consists of several main elements:

• housings made of dielectric (non-conductive) material - ceramics or plastics,
• contacts - spring-loaded brass parts that are needed for reliable connection of conductive parts and uninterrupted current flow,
• terminals - adapters for connecting cables.

The contact sockets of the device are made recessed into the body. Their arrangement prevents accidental short circuits.

Telephone sockets can be single or multiple. Single-socket models allow you to connect one telephone set, multi-socket - several. The RJ 11 socket is a single socket, it can be used to connect only one telephone.

RJ 11 connection

RJ 11 has two wires, so it's easy to connect it yourself at home. To do this, you will need to connect the two ends of the wire with certain contacts in the socket, so that they are mirrored in the plug and in the socket. For installation you need:

• two-core cables 0.3-0.5 mm thick,
• screwdrivers - flat or Phillips, depending on the type of screws, with an insulated handle,
• drill,
• insulation stripping tool
• tester,
• a tool for crimping contacts - you can not use it, but crimp the contact plates with a screwdriver, but then the plug will not look so neat.

The video shows how to properly connect a telephone jack to the line.

Important! Work on connecting the outlet should be carried out with rubber or latex gloves. The voltage in the low-voltage network reaches 60 V, dropping to 12 V when the handset is lifted. If they try to call the phone, a voltage of 120 V will appear in the wires, that is, it can shock. At this voltage, it is not dangerous, but unpleasant.

First of all, you need to turn off the electricity. Next, you need to strip the insulation off the wires. This is done with side cutters, pliers or an ordinary knife. It is necessary to release the wires from the insulation carefully so as not to damage the core of the telephone cable itself, otherwise it may break in the future.

Do not burn the insulation and then remove it with your fingers. Hot plastic can burn you, and it's hard to remove the insulation neatly with this method. It is necessary to strip the wires at a distance of 4 cm from the end.

It is advisable to strip the wires with a margin: they are thin and fragile, they are easy to damage. The excess part, if it remains, is easy to hide under the socket housing. With a closed installation, for convenience, the wires are made to protrude 5-8 cm beyond the wall surface.

Next, using a tester, check the polarity of the wires. Typically in telephone jacks, the red wire is positive and the green wire is negative. But it is better to check the polarity, since it is not known how the wires were located before. If it is not possible to use the tester, then connect the cables according to the diagram that is attached to the device.

To check if the line is working, you need a voltmeter (multimeter). The voltage on the line should be 40-60 V.

After that, the wires are connected to the outlet according to the diagram. To do this, you need a screwdriver - the wires are inserted into the connectors and the screws are tightened, clamping them well.

If you need to install the outlet in a closed way, then first a markup is applied to the wall showing where the device will be located. Then, according to the markings, holes are made using a perforator and the structure is fixed with self-tapping screws. A protective cover is installed on top. At the end, the device is also tested.

If you are mounting a new point and there is no space for sockets on the wall, then first they make a recess for them - a socket box. It is drilled using a special nozzle-crown on a puncher with a diameter of 6-7 cm. Channels for laying wires are also cut with a puncher. If there is no puncher, this can be done with a hammer and chisel. But such work is much more long and laborious.

After that, install the device in the socket, making sure that the cables are not intertwined. Then the socket is fixed with self-tapping screws and spacer screws. The gaps between the socket and the wall are covered with gypsum mortar.

When the solution hardens, install the protective edging and front panel. The protective edging in modern models is attached with latches, and the front panel is fixed with screws.

Wiring diagrams

Telephone sockets will be connected according to certain schemes. Their wires are marked with color or numbers, there are different options, but the telephone socket connection diagram is usually attached to the device.

Polarity is usually not that important, but individual devices may not work properly if not observed. The connection diagram is shown in the figure.

The twisted pair cores are also marked according to different standards, which are given in the tables. There is an old, new and German schemes.

In order to properly connect the phone and get a well-functioning line, you need to take into account some recommendations.

1. Most often, an internal (hidden) outlet is installed. It fits well into any interior, but it is more difficult to mount it, in addition, it can damage the decorative wall finishes. Open-type sockets are easy to maintain, install and dismantle, the finish does not deteriorate during their installation, but they do not look very aesthetically pleasing.
2. Preference should be given to products from well-known manufacturers. These include the companies Legrand (Legrand) and Vico.
3. If the socket does not come with a wire marking scheme, then you can use the tables above. In the new marking, the positive wire of the RJ 11 socket has the same color as the negative wire, but with the addition of white. In the old scheme, positive is green and negative is red. In the German version, the negative is white and the positive is brown.

Mounting other types of devices

The RJ 11 socket can be replaced with an RJ 25 model. This is undesirable, but if you accidentally bought a 6-pin version, then use only 3 and 4 for connection. They are marked in the same way as the two pins of the RJ 11 model.

A universal socket (RTSHK-4 + RJ-11) is suitable for old-standard telephone sets. You can also use an adapter from the old standard to the new one.

Conclusion

Using the diagrams and recommendations in the article, you can independently install a new standard telephone socket and connect a telephone to the line. Connecting a device with two contacts is not difficult, the main thing is to choose models from well-known manufacturers when buying, and when connecting an outlet, carry out the work carefully and observe the polarity.

How to connect a telephone socket yourself?

The telephone socket is inherently a low-current type of socket devices, the main functions of which are:

1. Connecting wired and wireless devices to the appropriate network and providing telephone communication.
2. Connecting modems and faxes.
3. Connection and organization of mini-ATS.

Connecting a telephone socket in practice is much easier than the electrical variety. However, this process still requires caution and accuracy, since for its implementation it is necessary to perform a series of electrical work associated with high voltage.

Installation and connection of such devices is ideal for people with little experience in this area, or beginners who are just gaining relevant experience.

Previously, this process caused fewer questions, since there was a single standard governing the installation of such devices. To date, there are several European standards called Registered Jack (RJ). There are several different ways to connect telephone sockets, this process can be done independently with RJ-14 and RJ-25 devices.

Features and connection diagram

RJ-11 socket

Telephone sockets have their own individual connection features, if we talk about the modern and most common RJ-11 and RJ-12 standards, they have the following connection nuances:

1. The design of the device may include 2-4 contacts, which are small metal plugs. Between these elements, the deepening of the cores of the supply wire is required.
2. The phones themselves are connected exclusively through 2 central contacts.
3. To mount fixtures with the specified standard, professional craftsmen use a special kind of working tool called a crossover knife. However, if its frequent use is not planned in the future, then you can limit yourself to the most ordinary knife with a sharpened blade. Such a tool is used to deepen the cores; when cutting through the insulating layer, contact will be provided.
4. Before straightening the cores, it is necessary to remove the outer layers from the wire, 4 cm is enough to carry out such stripping.
5. For internal laying, it is recommended to use the KSPV cable, which has a single wire core in its design, which is most often made of copper. The outer sheath is usually made of plastics with a white color. The TRP cable is most often used as a distributor.

Necessary tools and materials

Depending on the type of telephone jack, as well as the standard used, different tools and materials may be required.

1. A screwdriver that, according to the type of working surface and dimensions, corresponds to the screws used to fasten the fixture. The screwdriver handle must be insulated to avoid injury. electric shock.
2. Socket box.
3. The cable, if it is not replacing the old device, but laying a completely new one.
4. A puncher, as well as a cable, will be needed if a new outlet is being installed.
5. The outlet itself.
6. Knife with a sharp blade.
7. Self-tapping screws.
8. Wire cutters.
9. Insulating tape.
10. Universal multimeter or tester.
11. Protective gloves.
12. Single and double sided adhesive tape.
13. Graphite pencil and a brightly colored marker, which you will need for marking.

Step-by-step instruction

Initially, a simple way to connect a universal telephone jack will be considered. To date, the most common devices that comply with European standards RJ-11 and RJ-12.

In order to connect them, you must adhere to the following algorithm of actions:

1. Initially, you will need to turn off the power supply and wear protective gloves, since the voltage in the telephone network is 60V, and in working condition it can reach 110-120V.
2. Using side cutters, remove the insulating layer from the conductors, while it is important not to touch the cores themselves. The length of the stripped cable should be about 4 cm.
3. Using a tester, determine the polarity of the contacts.
4. Connect conductors to contacts. In a telephone jack, the red wire is negative and the green wire is positive. It is not necessary to follow the polarity connection rules, but there is a certain risk that in the future the telephone will give its own from time to time during operation.
5. Connect the cable cores, then tighten and ensure secure fixation using special screws for clamping.
6. Some models have 2-4 contacts in their design, which have a fork shape; these elements are made of steel. In such a situation, 2 center contacts are used.
7. Fix and fasten the telephone socket on the wall surface. This can be done using double-sided tape, but most effective way is the use of self-tapping screws.
8. Close the cover of this device.

There are varieties of telephone sockets of a hidden type. The connection process for them has no fundamental differences with the connection of classic device options.

Significant differences exist only in the process of their installation and are as follows:

1. Mark the future location of the telephone socket on the wall surface.
2. First, you will need to make a hole in the surface with a puncher, it will be needed for the subsequent installation of the socket. Fixation and fastening of this element is achieved through the use of self-tapping screws.
3. Fixing the device inside the mounting box can be done using spacer screws for special purposes.
4. Put on an external protective case, after which you can return the voltage to the network and test the installed device.

At the same time, you need to know that absolutely any kind of telephone sockets can be not the usual single, but double devices. Such devices are usually installed in offices or other premises where there are several telephone sets with different numbers, but sometimes it may be necessary to install them at home.

The installation or connection process has no fundamental differences from the work carried out with a single design. The only change is an increase in the number of conductors that need to be connected.

Types of telephone sockets

When considering different types of such devices, one of the main classifications is their division according to the method of installation:

1. Devices for external installation.
2. Devices with internal wiring.

A secondary classification applicable to both types is the division of these devices according to the number of connectors available:

1. Single-socket models are designed to connect 1 device, they are the most popular option for installation in private houses or residential apartments.
2. Multi-connector models allow you to connect several different devices at once, most often found in offices and service premises.

Also, sockets with different connectors are presented on the modern market.

RTSHK-4

This parameter is determined by the type of standard used:

1. RJ-11 is one of the most common options, it implies the presence of 2 conductors in the design. Such devices are most often found and are recommended for installation if there is a linear-type telephone line to which the device is connected.
2. RJ-12s are less common because they are rarely used for domestic purposes. The main purpose is to connect to office PBX or a number of varieties network cards.
3. RJ-14 has 4 conductors in its design and the same number of contacts. It is a universal connector designed and suitable for most modern models of telephone equipment. To connect and ensure the operation of one line, contacts 2 and 3 are used, if for some reason several lines are required, then the connection is made through contacts 1 and 4. Surface-mounted sockets must use a green and red conductor, which are usually located in the center of the fixture.
4. RJ-25 includes 3 pairs of working contacts in its design at once. Devices of this type are extremely complex and unsuitable for self-assembly. To carry out this process, you will need to involve a qualified specialist who understands electrical and telephony issues.
5. RJ-9 is a special type of connector, the main task of which is to connect the handset directly to the device.
6. RTSHK 4 is a technically obsolete type of sockets that were common in the USSR in the past; 4 wide contacts and a key are included in the design. Designed for a specific connection option in a one-piece way, for its implementation, the presence of a branch-type box is required. The presence of several telephone sockets within the same room contributes to the creation of a special electrical circuit, an additional capacitor is required to close it.

Regardless of the type of telephone jack, a special type of power cable will need to be installed inside this device. Different options do not have structural differences, all plugs have similar dimensions and connectors, but they may differ in the number of contacts available.

marking telephone wires

All the main issues related to the installation and connection of telephone sockets have been considered, summing up, we can give a number of the following useful advice:

1. The most popular today is the built-in type of devices, since it harmoniously fits into any room and is an extremely inconspicuous element. However, it must be borne in mind that its installation will take longer and the wall decoration will suffer.
2. It is best to purchase devices that were released by well-known and trusted manufacturers who have managed to positively establish themselves in this area. Today, such companies are Legrand and Vico.
3. On some models, there may be no pin numbering, usually applied to the body of the fixture. In this case, knowing the rules of color marking can help: green, orange or blue in combination with white are used to indicate positive contacts; the same colors, only monotonous and without the addition of white, indicate a negative contact.
4. If an old-style telephone socket is being installed, it also does not hurt to know the color marking rules that were used before: the orange, black or green conductor is positive; red, yellow or blue conductor must be negative.

Installation of telephone networks and other similar communications is much easier to perform compared to electric lines. This is due to the absence of voltage that is dangerous to human life and health. However, even here there are specifics and certain difficulties. For example, many people do not fully understand how to connect a telephone socket. A large number of Modern designs of telephones and connecting devices require careful selection of the most suitable option.

Types of telephone sockets

All telephone sockets are divided into three main categories:

• Sockets "Euro" built-in.
• Telephone sockets are external.
• Outlets of the old type.

All products differ only appearance. The connection order for each type is almost the same and does not have significant differences. In turn, all modern telephone sockets and connectors are also divided into three main categories.

The RJ11 model with two wires is very rare. Much more common is the RJ14 variant, where there are 4 wires and 4 pins. Most models of telephone sockets are produced for this type of connector. Connection of one home line is carried out using two middle contacts No. 2 and 3. Very often in offices it is required to connect a second telephone line. For such cases, contacts No. 1 and 4 are provided. If the design of the socket is consignment note, then the telephone line is connected to the two middle contacts with red and green wires.

There is an RJ25 socket that has three pins. It is undesirable to purchase such an outlet if you plan to connect it yourself. In the event that such an outlet is nevertheless purchased, one telephone line must be connected using contacts No. 3 and 4. Red and green wires are connected to them.

When connecting a telephone cable to any type of socket, any RJ11, RJ14 or RJ25 connector will work. They have same sizes and differ only in the number of contacts. Color marking of wires is observed according to the generally accepted scheme. For example, an overhead outlet uses red and green wires that extend from the pins to the connector.

In a house or apartment, the connection of a telephone socket is usually carried out with a two-wire wire. In offices and other places where multiple telephones are used, telephone jack connections can be made with a two-, four-, or six-wire telephone cable. AT computer networks apply.

Preparing to connect

Before proceeding with an independent connection, it is necessary to carry out some preparatory work. For installation work, you will need the socket itself, side cutters or another device for stripping insulation, a screwdriver and a tester.

Old-style sockets of the RTSHK-4 brand are still in use, so from time to time you have to deal with their installation or reinstallation. To connect them, you need a two-wire cable with a cross section of 0.3 to 0.5 mm 2, for example, KSPV 2x0.5 or TRP. When installing sockets, a capacitor with a capacity of 1 microfarad was used to check the telephone line at the time of the call. It was used only for one outlet.

Currently, socket outlet capacitors are not required, which improves the quality of telephone lines. Therefore, their installation requires a minimum of tools and materials.

Instructions for connecting a telephone socket

During the connection, certain rules and sequence of work must be observed. All actions must be performed with protective gloves. The fact is that even in a calm state, the telephone line is energized by about 60 volts. When touching the wires with wet hands, there are quite unpleasant sensations. The voltage during a call becomes more dangerous, reaching already from 100 to 120 volts.

Using side cutters or other tools, you need to carefully remove the insulation from the wires so that notches form on the cores. Notches on the cores can later lead to a fracture of the wire.

Next, the cover of the socket housing is removed, inside which there are red and green wires, which are located according to the standard on the upper terminals. They are connected to a telephone line. Quite rare is the location of the wires on the middle pins Nos. 3 and 4, or even on Nos. 2 and 5.

The wires in the outlet must be connected to the telephone line in the appropriate way: red is connected to the minus, and green to the plus. Polarity when connecting is not of great importance, however, for some telephones it can be very important. The polarity in the telephone line is determined using a tester. If the connection is incorrect, the voltage readings on the device will be negative. If the tester is not available, you can use a cut raw potato, where the bare ends of the wire are stuck. Near the positive end, the color of the potato will be different.

After connection, the socket housing is fixed in the right place using double-sided tape. After that, the lid snaps on and the phone's performance is checked.

Hidden installation of a telephone socket

A more difficult option is to install a hidden telephone socket. To install it, you will need a hammer drill with a crown, fasteners, a stripping tool, screwdrivers and a tester.

Previously, a telephone wire is laid to the installation site, laid in a strobe, cable channel, or laid along a plinth. After that, the most suitable nozzle for the puncher is selected in order to make a hole for the mounting box to a sufficient depth. The box is installed in the finished hole and secured with dowels or self-tapping screws.

Then the telephone cable must be connected to the outlet in the same way as for the overhead product. The socket housing with the wire connected is placed in the junction box and fixed with spacer screws flush with the wall surface. Finally, the outer frame and overlay are installed, after which the operability of the outlet is checked.

Wiring diagrams for telephone sockets

Various schemes can be used to connect telephone sockets. The presented option covers all possible connections, up to a parallel phone. If necessary, especially in offices, the phone can be connected to a modem.

The scheme is complemented by other useful elements. For example, in order to turn off the parallel telephone, a special switch is provided. To equalize the signal on the line, special microfilters can be installed. In addition, one or another connection scheme depends on the parts and elements used. You should take into account the specifics of the house, apartment or office, their layout and other features.

And telephone sockets. In terms of connection complexity, a telephone socket is a simpler element than an electrical one.

At the same time, installation work is much safer, since there is no life-threatening voltage in this device. Of course, this does not mean that you should not follow the rules of elementary electrical safety, because in standby mode the voltage between the wires of the telephone line is about 60 V. You should also take into account the fact that disconnecting the telephone line is much more difficult than part of the power wiring. Another unpleasant moment is the appearance of a voltage of 120 V in the circuit at the moment a call arrives at the installed telephone from any subscriber.

To understand how to connect a telephone socket, you should carefully consider its internal structure and the procedure for installing this device.

Installation of a telephone socket

Installing a telephone socket involves the following sequence of actions:

1. Disassemble the body. To do this, unscrew the bolt that secures the cover to the body with a screwdriver.
2. If this product is intended for indoor installation, the back box must be installed for it first. To do this, a hole is drilled in the wall using a special crown worn on a drill. Further, a cable is connected to this hole (it is better to give preference to a four-wire cable), which is released from the junction box by about 15 cm. box. It is also worth mentioning that the correct laying of the telephone wire should be carried out in the wall under a layer of plaster, while its intersection or location near power cables is not allowed.
3. How to properly connect the telephone cable to the socket? Remove the insulation 5 mm from the edges of the conductors of the telephone line wire. For this, a special tool or the most common knife can be used. If the installation of the outlet is carried out by professionals, then they crimp the end of each core with the installation of a special terminal on it.
4. The telephone cable is connected to those terminals of the telephone socket to which the red and green conductors are connected. The connection diagram may differ depending on the type of connector used in the this device. However, color marking in most cases is respected. In this case, the red color of the conductor insulation means that a minus must be connected to it, and green provides for the connection of a plus. To determine which of the line wires is a plus and which is a minus, you can resort to using an ordinary tester. As a rule, when connecting modern telephone sets, polarity is not important. However, when installing the outlet, the trial and error method is usually used: if the phone does not work, then you need to change the polarity.
5. Assemble the socket housing.
6. Perform a phone test.

If this simple sequence of actions has been performed correctly, then connecting the telephone socket is not difficult.

Wire selection

To carry out the wiring of the line according to the layout of telephone sets in the apartment, use the TRP 2 × 0.4 or 2 × 0.4 wire, which has two separate copper cores covered with polyvinyl chloride (PVC) insulation. A feature of this cable, commonly called "noodles", is the presence of a dividing strip between its cores. It is very convenient to drive small nails into this strip to secure the wire to the surface.

• This is a single or double socket (RJ11). It is one of the most common types of these devices. Uses a two-wire connection. It can be used to connect home or office phones. In this case, to connect this socket to the line wires of the telephone line, contacts marked with numbers 2 and 3 (green and red) are used.

• Connector 6P2C. (RJ12 standard). Can be produced in single or double version. Most often, these sockets are used to connect mini-PBXs in offices.
• (RJ14 standard). Such a product can be used to connect two telephone lines or four-wire telephone sets. However, since most apartments have only one line, its wires are connected to the middle terminals (numbers 2 and 3) of such an outlet.
• 6P6S (RJ25). Has three pairs of contacts. Its acquisition is not advisable for installation in a private apartment, which has only one line with a two-wire telephone. If you still have to install such a device, then the wires are connected to the upper terminals (3 and 4 numbers).
• 8P8C (RJ45). An eight-wire connector used to build local area networks.

Since the listed connectors can be used in sockets of different standards (the main thing is that the number of wires in the connection matches), there is considerable confusion in the names of connectors and socket models.

To install several telephones connected to each other, you can use the parallel connection of sockets. To do this, in each connection that is present in one device, you should connect the wire of the same name from the neighboring one.
