Punch for rj 45 sockets. Do-it-yourself crimping of an RJ45 power socket

Most people live in separate apartments and private properties. And often for each room it is necessary to solve one small but rather insidious problem: accessible, low-cost, but effective way create an access point to connect to the Internet. It would seem that the answer is obvious - purchase, configure Wi-Fi router and forget about all the problems. However, wired Internet still remains the most common and reliable solution, because such a signal is much more stable. This leads to another problem - how to hide the Internet wiring? Usually it is mounted in walls and connected to sockets, although not of a completely standard type: they are called computer or simply Internet sockets.

What is an Internet socket

The main difference between an Internet outlet and a regular electrical outlet is that it has its own unique connector, which is connected to a special type of wiring called twisted pair. It is unique in that it contains 8 separate copper wires, twisted together into 4 pairs. Thanks to this connection system, existing electromagnetic interference is leveled out, which ultimately ensures high data transfer rates (up to 1000 Mbit/s).

The Internet socket has a special connector to which a twisted pair cable is connected.

The response connector is called RJ-45/8p8c. It is mounted on the cable using a special tool, and the connector wires must be located in a strictly defined order.

The sequence of colors of wires connected to the connector contacts is determined by the standard diagram

Classification of Internet outlets

IT specialists classify Internet outlets according to their distinctive features:

Algorithm for laying Internet cables in walls

The most correct, but at the same time difficult to implement solution for laying an Internet cable in a home (office) environment is to install it inside the walls. The advantages of such wiring are obvious: the cable does not get tangled underfoot and does not affect the decorative design of the room. A significant disadvantage of in-wall installation is that in the future there may be problems with access to the cable for repair or maintenance. But with proper cable routing along grooves in a corrugated PVC pipe, you can not only minimize the risk of a malfunction, but also provide relatively easy access to the twisted pair without complex dismantling work.

Before you start laying the Internet cable, it is worth marking the places where it will be located. Remember that unshielded twisted pair cable is made of copper, which is very sensitive to electromagnetic interference. Try to keep the distance between computer and electrical wiring at least 50 cm.

How to pinout an RJ-45 cable

When crimping a twisted pair cable, you must adhere to a certain pinout (color scheme). There are two generally accepted connection standards.

To select the correct connection color scheme, it is worth contacting your Internet service provider and obtaining from them information about what scheme was used during the connection.

We carry out the work in the following order.

Connecting RJ-45 with two twisted pair wires

A two-pair RJ-45 cable uses data transfer rates of up to 1 Gb/s.

The two-pair cable is connected to one side of the socket contacts

The pinout of a two-pair cable is the same as for a four-pair cable. Only instead of eight multi-colored wires, only four are switched: white-blue, blue, white-orange and orange. Then the cable is crimped, the socket is assembled and installed, and its functionality is checked.

How to crimp an RJ-45 cable onto the contacts of an Internet socket

When pinouting the cable to the terminals of the Internet socket, you should crimp them. The performance of the Internet connection will depend on this. Based on a similar process for conventional electrical outlets, one would assume that crimping an Internet outlet is a similarly labor-intensive process involving removing the protection from each individual wire and then connecting them with bolts. In reality, everything is much simpler and faster. The contacts of an Internet cable are designed in such a way that when a conductor is firmly connected to them, they cut the insulating coating, resulting in contact with the copper core. Because of this, stripping each wire is not necessary.

Typically, an extractor is used to crimp socket contacts - a cross-connecting knife.. The work should be done carefully to avoid damage to the cable.

The cable is crimped into a computer socket using a cross-connecting knife.

Signal check, testing

After pinouting the Internet socket and the RJ-45 connector at the opposite end of the cable, you should make sure that the installed line is working. The test is best done with a special device called a cable tester.

It is better to check the functionality of the socket using a specialized device.

It consists of two parts - a signal generator that transmits short electrical pulses using encrypted codes, and a receiver that processes these codes. The generator connects to your router, and the receiver connects to an internet outlet.

After the transmission of electrical signals, they are compared. If all connections are working properly, two lights will light up in sequence. led light bulbs Green colour on the housing of the generator and receiver. If there is a break somewhere on the cable or a short circuit is visible on the Internet outlet itself, then one or both LEDs will not light up at all.

Review of products from famous brands - manufacturers of Internet sockets

Without exception, all Internet sockets are divided into two large subgroups: mortise and external. The manufacturer usually only slightly changes the mechanism for attaching the socket to the wall, but the principle of connecting it to the Internet always remains the same. Let's look at the most common manufacturer brands.

Legrand

Internet sockets from the French manufacturer are not only one of the most popular, but also have one of the best cable retention mechanisms. The connection diagram for Legrand sockets does not differ from generally accepted standards. At the same time, any Internet outlet can be connected either by type A or type B. The color schemes for connection are located on the terminal of the outlet itself.

Pinout and connection of the Legrand socket is carried out according to the generally accepted scheme

Viko ("Viko")

Viko sockets are cheaper than Legrand's, while their quality remains the same high level. The body is made of durable polymer materials, and the internal assembly is very ergonomic.

Viko sockets are an economical and high-quality solution

The only major difference from other manufacturers is that there are no hints on the terminal inside in the form of a color connection scheme. Therefore, pinouting should be done very carefully.

Lezard

Switches and sockets of the Lezard brand are produced by the Turkish company Dernek GROUP. They do not have any distinctive features.

The Lezard socket is connected and installed quite simply

Schneider (“Schneider”)

This outlet is connected in the same way as others. Often it can be double, then you will have to connect two cables from the router, since there is a parallel connection network equipment not supported.

The most common version of the Schneider socket has two outputs

Video: connecting a Schneider Internet outlet

Connecting an Internet network via cable is the most common method today. Wired Internet is still considered the most stable. For ease of connection, there are special sockets, thanks to which any cable can be hidden in the wall. This seemingly time-consuming task of connection and installation is actually solved relatively easily, without requiring the use of expensive tools. Therefore, anyone can connect an Internet outlet.

In many families, several devices are connected to the Internet: we can’t imagine life without the World Wide Web, so everyone needs their own line. They work mainly using a wireless protocol - Wi-Fi, but there is still a wire, since wired Internet is still more stable than wireless. During repairs, all wires are hidden in the walls and “Internet” wires are no exception. They, like electric ones, are plugged into sockets, only of a different standard: they are called computer or information. They can have different connectors, but the most common is RJ 45. You can do the installation and connection yourself, but since the connector looks unusual in appearance, there are more than two or three wires in it, and the connection is not ensured by soldering or twisting, you need to know , how to connect an Internet outlet and also the connector that should be inserted into it.

RJ-45 connector crimping

The Internet cable entering an apartment or house, most often called twisted pair, often ends in a small plastic connector. This plastic device is a connector, usually RJ45. In professional jargon they are also called “Jack”.

Its body is transparent, making the wires visible different color. The same devices are used on connecting wires that connect computers to each other or to a modem. Only the order of arrangement (or, as computer scientists say, pinout) of the wires can differ. The same connector is inserted into a computer socket. If you understand how the wires are distributed in the connector, there will be no problems connecting the Internet outlet.

Internet cable connection diagram by color

There are two connection schemes: T568A and T568B. The first option - “A” is practically not used in our country, and everywhere the wires are arranged according to the “B” scheme. It is necessary to remember it, since it is what is required in most cases.

To finally clarify all the issues, let's talk about the number of wires in a twisted pair. This Internet cable comes in 2-pair and 4-pair versions. To transfer data at speeds up to 1 Gb/s, 2-pair cables are used, from 1 to 10 Gb/s - 4-pair. Today, apartments and private houses are mostly supplied with flows of up to 100 Mb/s. But with the current pace of development of Internet technology, it is quite possible that in just a couple of years the speeds will be measured in Megabits. It is for this reason that it is better to immediately expand a network of eight rather than 4 conductors. Then when changing speed you won't have to redo anything. Just the equipment will use larger number conductors. The difference in cable price is small, and sockets and connectors for the Internet still use eight-pin ones.

If the network is already wired in two pairs, use the same connectors, only after the first three conductors laid according to scheme B, skip two contacts and place the green conductor in place of the sixth (see photo).

Crimping a twisted pair cable into a connector

There are special pliers for crimping wires in the connector. They cost about $6-10 depending on the manufacturer. They are more convenient to work with, although you can get by with a regular screwdriver and wire cutters.

First, the insulation is removed from the twisted pair. It is removed at a distance of 7-8 cm from the end of the cable. Underneath there are four pairs of conductors of different colors, twisted in twos. Sometimes there is also a thin shielding wire; we just bend it to the side - we don’t need it. We untwist the pairs, align the wires, spreading them in different directions. Then fold according to pattern “B”.

The procedure for sealing the RJ-45 connector in the connector

Wires in in the right order We pinch it between the thumb and forefinger, lay out the wires evenly, tightly to each other. Having aligned everything, we take wire cutters and cut off the excess length of the wires laid out in order: 10-12 mm should remain. If you attach the connector as in the photo, the insulation of the twisted pair should begin above the latch.

We insert the twisted pair with the cut wires into the connector. Please note that you need to take it with the latch (protrusion on the lid) down.

Each conductor must get into a special path. Insert the wires all the way - they should reach the edge of the connector. Holding the cable at the edge of the connector, insert it into the pliers. The handles of the pliers are brought together smoothly. If the body has become normal, no special effort is required. If you feel that it “doesn’t work”, double-check whether the RJ45 is installed correctly in the socket. If everything is fine, try again.

When pressed, the protrusions present in the pliers will move the conductors to the microknives, which will cut through the protective sheath and ensure contact.

This connection is reliable and problems rarely arise with it. And if something happens, it’s easy to re-terminate the cable: cut it off and repeat the process with another “jack”.

Video tutorial: crimping an RJ-45 connector with pliers and a screwdriver

The procedure is simple and easy to repeat. Perhaps it will be easier for you to do everything after the video. It shows how to work with pliers, as well as how to do without them, and do everything with a regular straight screwdriver.

How to connect an internet cable to a power outlet

Now we come directly to how to connect the Internet outlet. Let's start with the varieties. Like regular electrical sockets, information sockets come in two modifications:

According to the number of connection points, there are single and double computer sockets.

Although computer sockets differ in appearance, the principle of connecting conductors is the same. There are special contacts equipped with microknives. The protective sheath is cut through the inserted conductor. As a result, the metal of the microknife contacts fits tightly to the metal of the conductor.

How to connect a computer wall socket

Inside each outlet there is a hint on how to place the wires when connecting the Internet cable. Manufacturers stick on the color scheme that we saw when crimping the connector. There are also two options - “A” and “B”, and we also use option “B”.

The case is mounted on the wall, usually with the cable inlet up and the computer connector down. The next steps are simple:

Connecting a twisted pair cable to an outlet is really a simple procedure. Even the first time it will take a few minutes. You can see again what they do and how in the video. It first shows the connection of an Internet cable with 4 wires, then with 8.

How to connect an internal Internet socket

We won’t describe the installation of the plastic box - that’s a different topic. Let's look at the features of connection and assembly. The main problem here is how to disassemble computer sockets. When connecting conductors to them, you need to get to the contact part: a small ceramic or plastic case with built-in microknife contacts. The conductors are connected to this mounting plate, and then the housing is reassembled. And the whole problem is that different manufacturers they are assembled/disassembled differently.

For example, from the popular manufacturer of computer sockets Legrand (LeGrand), in order to get to the connectors in the Legrand Valena RJ45 computer socket, you need to remove the front cover. Under it you will find a white plastic impeller (as in the photo), with an arrow on it.

You need to turn the impeller in the direction of the arrow, after which you will have the housing and the contact plate in your hands. It has color-coded conductors. The connection is no different, except that first you need to thread the twisted pair, and then separate the wires.

For clarity, watch the video.

Another popular manufacturer of such equipment is Lezard. His system is different. The front panel and metal frame are fixed with small bolts. They are easy to unscrew, but the internal contact plate is held in place by clamps. Assembling and disassembling Lezard computer sockets (Lezard) in in the right places you need to press out the contacts with a screwdriver.

To remove the plastic contact group from the housing, you need to press the latch located on the top. After which you will have a small box in your hands. But that's not all. It is necessary to remove the plastic cover that covers and presses the conductors. Remove it by prying it off with a screwdriver side lobes. The plastic is elastic and the effort required is quite decent. Just don't overdo it: it's still plastic. After that, the wiring is standard: according to the markings on the sides (do not forget that we are using diagram “B”).

If you know how to connect an Internet outlet, it’s not difficult to figure out even an unfamiliar model. And now you can upgrade your network yourself (increase the length of the twisted pair, move the computer to another location, make another connection point, etc.), without involving specialists. One more question remains: how to connect double sockets. Two cables are connected to them and then they are connected according to color scheme. This is possible when your network is formed by a modem or two Internet lines are connected. Is it possible to connect both inputs with one cable? It’s possible, but you need to avoid getting confused in the color designation of the wires in the further wiring of the network (remember which color you used instead of which).

There are two main types of sockets - for hidden and external cable routing. In this case, we consider independent crimping of a hidden RJ45 network socket. But there are no fundamental differences from the second one in the execution of work, with the exception of the presence of additional work on installing the socket box! Therefore, focusing on this example, you can easily crimp a power socket of a hidden or external type yourself.

So, let's start with the fact that the twisted pair is brought out into the socket box.

If the ends of the cable are too long, they can be cut off.

After this, remove the top layer of insulation. There are special tools for this. If they are not there, then a similar operation can be performed using a regular stationery knife. The main thing is not to damage the twisted pair wires! Otherwise, the cable will have to be cut again and stripped of the outer insulation again.

It is not necessary to “fluff” the twisted pair at this step!

Next we need the power outlet itself. This Schneider power socket model uses a clamping mechanism for crimping cables. The clips in the photo below are raised. By the way, they also have a pinout diagram that will be needed in further work.

We insert a twisted pair cable through a special hole in the clamp.

Next, the cable needs to be fluffed up. Those. separate paired wires. After this, we install each individual wire in the corresponding color socket on the latch. At this stage, a reasonable question of choosing a pinout may arise. On the color scheme drawn on the socket body, there are two options - scheme A and scheme B. The maximum connection speed depends on the correct choice of pinout. Those. instead of a gigabit you can get 100Mbit, or instead of 100MBit you can get only 10.

It’s easy to determine the desired pinout! To do this, you should look at the crimped end of the patch cord you have (for example, cut off from the cable) and look at how the wires are located there. If, as in the photo below, then crimping the power socket should be done according to diagram “A”

If the first wire in the connector is “white-orange”, then we use circuit “B”.

In general, we insert the wires into the holes corresponding to the color of the selected circuit.

Next we snap the latch.

You can trim off excess wires for aesthetics.

If necessary, we crimp the second socket in a similar way.

Next, install the socket in the socket box. In this case, it is attached with screws to the body of the external unit for external wiring. If the installation is carried out in a regular socket box, then the Schneider power socket has clamping “ears” that perfectly fix it in this case.

It is impossible to build any modern structured cabling system without a socket. To install it, you can call a qualified technician, but you can do this work yourself. Internet connection cables are low voltage, making work safe and easy.

The socket is standard RJ-45, but has different appearance depending on the manufacturer. In the catalog of companies producing cable products and accessories, you can find a photo of the rj 45 socket.

Types and applications

The most popular combination computer socket. It additionally has a telephone connector, which allows you to connect not only to the Internet, but also to landline phone. It can be presented in several versions - surface-mounted or rj-45 socket for indoor installation.

The latter will require wall slitting, but will retain the presentable appearance of the room. The rj-45 surface-mount socket is widely used in offices and premises where there are a large number of wires and their external installation in boxes and mini-ducts is appropriate.

Sockets can be multi-port or single-port. Two or more ports will allow you to connect large quantity equipment, therefore the option is also relevant when creating workplaces in office premises, but usually sockets from one or two modules are used, and for a larger number a patch panel is used.

The socket consists of several parts: a base, a plastic cover, a board with a standard type connector, connectors for connecting wires, a tie for securing the cable and the connector itself.

In appearance, the socket is similar to a similar rg-11, however, the connectors are designed for 8 contacts, and not half as many, which allows you to use it as a telephone.

The rj-45 pinout is done using color markings that comply with T568A or T568B standards. It is worth considering that the standard must be the same for the entire local area network, otherwise connection problems may arise.

Instructions on how to connect an outlet

The connection diagram is not difficult. You need to cut the insulation from the wire by 2-3 centimeters, untwist the 4-pair wires, and clear the insulation, manually, but preferably using a stripper so that the wire extending beyond the socket is necessarily covered with insulation, and the exposed part is in the socket .

If you open the socket housing, you can see that all connectors are marked a certain color to make connection easier. To clamp the wire in the latch, you need to press it with a knife or screwdriver.

Manufacturers of quality products, as a rule, include an extractor along with the socket, which helps to strip and snap the wires. This is a very convenient tool that you can purchase yourself at an affordable price from Chinese manufacturers or from branded ones for twice the price.

Special pliers for stripping insulation will also be useful. Their price is identical to the extractor and during use it is possible to adjust the depth of the cuts. These clamps will help you work with various types of twisted pair cables: UTP, FTP, STP.

When the wires are secured, you can screw the front panel and check the functionality with a special connector or immediately plug in the power supply to make sure that the work completed is correct.

The T568B standard has the following pinout: 1 – white-green; 2 – green; 3 – white-orange; 4 – blue; 5 – white-blue; 6 – orange; 7 – white-brown; 8-brown.

The T568A standard is used more often, wiring: 1 – white-orange; 2 – orange; 3 – white-green; 4 – blue; 5 – white-blue; 6 – green; 7 – white-brown; 8-brown.

Thanks to the color marking, it is very easy to crimp the cable into the socket yourself.

When using a shielded wire, it is necessary to use an appropriate socket, otherwise it will act as an antenna, which will immediately affect the throughput and, as a result, the speed of the Internet.

• Only grounded equipment should be connected to the STP and FTP cable;
• It is necessary to use only whole pieces of twisted pair, otherwise it will lead to significant losses. In case of urgent need, the pieces are twisted using connectors;
• At home and in small offices, it would be advisable to use a socket with one or two modules; a larger number can lead to tangled wires. It is better to space the sockets apart, leaving a certain distance between them;
• To ensure that the groove in the wall when routed internally to the socket is smaller or completely absent, it is possible to lay a twisted pair cable under the baseboard;
• If there are no special cable mounts available, you can make them yourself from tin wiring. To achieve this, it is possible to nail the cable with small nails or screw it with self-tapping screws every 30-50 cm.

Wall mounting

As mentioned above, you can attach the socket in several ways, after first selecting the optimal number of ports for a given room.

To hang a wall-type outlet, after installing the cable into the connectors, you need to attach its back wall with dowels to the wall and put on the top cover.

Installing an internal outlet will take more time. After disconnecting the cable, you need to drill a hole in the wall for the socket using a hammer drill and straighten it using a chisel and hammer.

The wall between the sockets is being chipped. If you are connecting to the high-speed Internet, then the strobe must also be routed to the distribution box.

A socket box is inserted into the finished hole in the wall and sealed with plaster mortar. The cable goes through the groove to the installation box, and from it to the socket, which is securely fixed in the installation box using self-tapping screws.

After completing the above work, all that remains is to put on top part sockets Despite the installation difficulties, hidden way allows you to maintain the aesthetics of the room and avoid the use of boxes and mini channels on the walls.

These products can be purchased from foreign and domestic manufacturers. The best power sockets, which are distinguished by their quality and durability, are made by companies such as Legrand, Schneiderelectric, Vico, R&M and others.

Photo of rj-45 socket

Despite the rapid development wireless communications, RJ-45 outlets are still a must-have element of a modern building's structured cabling system. We suggest considering their structure, types, pinout options and installation methods. The apparent simplicity of the question can be misleading, since there are certain nuances that need to be paid attention to.

Design features

Despite the variety of types of twisted pair sockets, their design is almost identical, with the exception of small details. As an example, let's look at a typical external single-port device.

Rice. 1. Basic elements of an external RJ-45 socket

Designations:

• A – plastic cover.
• B – base.
• C – functional board with a standard connector installed on it.
• D – convectors for connecting twisted pair cables.
• E – tie for fixing the cable.
• F – connector for connector.

Externally, the socket resembles an RJ-11 telephone standard; the main difference is the number of connector pins, there are eight of them, not four. Accordingly, a computer socket can be used as a telephone socket, but not vice versa.

Different types of devices may have minor characteristic features, but the overall design concept remains the same.

Types and characteristics

The main parameters of these switching devices are determined by the following criteria:

1. Number of ports.
2. Category.
3. Execution.

Let's briefly talk about each of them.

More doesn't mean better.

One of the main parameters is the number of ports. As a rule, there can be from one to four. If you need to use a larger number of connections, it is easier to install a patch panel, but such a need indicates an ill-conceived network layout. In addition, it should be taken into account that a large number of patch cords connected nearby causes some inconvenience.

Rice. 2. Krauler 4-port external socket

In practice, when organizing an office or home LAN, one and two-unit modules are mainly used.

This parameter is directly related to the characteristics of the cable used for installation computer network. We are talking about bandwidth, which determines both the data transfer speed and the ability to use special network technologies. Below is a table that shows the relationship between category and bandwidth.

Currently, when installing a LAN, cables with a category lower than 5e are practically not used.

Execution.

The method of mounting the switching device depends on this parameter. There are two versions:

• for external (external) installation (such sockets are shown in Figures 1 and 2);
• for indoor installation.

Internal two-port RJ-45 socket disassembled and assembled

As a rule, the choice of one version or another depends on how the LAN wiring is done. If it is external (for example, laid in boxes), external sockets are used. In cases where hidden wiring is done, the internal devices look more aesthetically pleasing.

Separately, it is necessary to highlight the sockets that are installed directly on the box. Technically, such execution can be considered both internal and external.

On specifications LAN execution has no effect.

Modular designs.

Speaking about performance, we cannot fail to mention modular designs. This solution allows you to assemble a socket in a standard case for a specific combination, for example, install it in RJ-45 and RJ-11 modules or with different categories.

RJ-45 pinout

There should be no problems with this, since opposite each contact group color coding is provided that corresponds to the T568A and T568B standards (can be marked with the letters “A” and “B”, as in the figure below).

It doesn’t matter which standard is used, the main thing is that it is the same type for the LAN, in otherwise problems are guaranteed. It is believed that we have adopted a “crimp” type T568B, but this is a rather conditional statement.

If you do not know which standard your provider uses, then you can install it using the pinout of the connector installed on the cable entering the apartment.

Detailed connection instructions

Let's start with the tool that you will need to seal twisted pair sockets. Ideally, it is advisable to purchase a universal extractor (shown in Figure 9). It allows you to press and cut the rest of the wire in one movement. Thanks to Chinese manufacturers, such a universal tool costs about 3-4 dollars. The price of branded products can be 2-3 times more expensive.

Rice. 9. Universal extractor

This tool has a special mechanism that allows you to press the wire between two contact knives and cut off its excess (3 in Fig. 9). In addition, it is equipped with a flat screwdriver (2) and a hook (1), which allows you to remove the wire if it is incorrectly terminated. The cost of a universal extractor is relatively low, but the benefits are quite tangible.

No less useful are universal insulation stripping pliers. They cost about the same as an extractor and can cut Ø3.5-9 mm cables such as UTP, STP, FTP. It is possible to adjust the depth of the cut.

It is not advisable to use a knife to strip the insulation, since in this case there is a high probability of damaging one of the twisted pair wires.

Having dealt with the necessary tools, let's move on to the algorithm for embedding a twisted pair cable into a switching device. We will assume that the cable has already been laid and the outlet space has been prepared. The procedure is as follows:

1. Using universal pliers, cut off the outer insulation layer from the end of the wire. It is enough to expose 4-5 centimeters. You need to act carefully so as not to damage the wires. If this happens, trim the damaged area, adjust the depth of the cut and repeat the operation.
2. After removing the insulation, level each pair. Please note that there is no need to clean them. Each pad contact has special micro knives that cut the insulation and ensure reliable contact and fixation of the wire.
3. We disassemble the socket. To do this, remove the front panel. To do this, you will need to unscrew the fixing screw or unfasten special latches (depending on the design). If you are using a modular socket, you will need to remove the modules from it.
4. We fix the cable on the module using a tie (E in Fig. 1) or another method provided by the design.
5. We insert the wires into the clamps, and it is necessary to adhere to the color markings of the selected standard. Do not try to recess the veins deeply; it is enough to simply fix them with a little force (A Fig. 11).
6. Using an extractor, we perform pressing (B in Fig. 11).

Rice. 11. A – cable with wires routed to clamps, B – pressed in with an extractor

At this stage we will do small retreat, regarding the use of improvised means for pressing. Sometimes you can find advice in which, in the absence of the necessary tool for pressing, it is recommended to use a utility knife or a thin slotted screwdriver. This approach can only be used as a last resort, when access to the network is urgently needed, but there is no tool at hand. But in the future, such a socket must be clamped. Otherwise, there is a high probability of losing contact between the wire and the latch after some time.

We also note that many branded manufacturers include a simple plastic extractor for each socket, which allows you to securely seal the wire, after which all that remains is to carefully trim off the excess.

1. After pressing, the module is installed in place. If the socket is external, then its base is screwed to the prepared area, so that the cable is supplied from above, and the connector is from below. When installing an internal socket, its base is installed in a prepared glass and fixed in it.
2. We fasten the front panel and then check its functionality. This can be done using a special tester, but it’s easier to connect a computer and check for a network connection. If problems arise, first of all check the correctness of the pinout; as practice shows, in 90% of cases the reason lies precisely in this.

When using a shielded cable, you must install an appropriate socket that has a shield connection. Otherwise, it turns into a large antenna, which will immediately affect the bandwidth, and, consequently, the data transfer speed. For the same reason, you should not use an STP or FTP cable if ungrounded equipment is connected to it.

Twisted pair LAN technology requires the use of continuous lines. Twists and adhesions are unacceptable; this leads to serious losses. If it becomes necessary to extend a piece of cable, special connectors should be used for this purpose.

Rice. 12. Twisted pair connectors

These devices are a box in which a board is installed with two RJ-45 connectors (A in Fig. 12), or twisted pair clamps, like sockets (B in Fig. 12).

It is not recommended to use sockets with more than two ports in domestic conditions. A large number of patch cords in one place will cause them to become tangled. It is better to space the sockets some distance apart.
