RJ 45 socket connecting wires. Computer internet socket RJ45

And consider such a thing as connecting an RJ-45 Internet socket. Although you can find some instructions on the Internet, there is little specific information on the RJ-45 pinout in the socket, mostly pictures, but detailed instructions absolutely not. Let's fill this gap.

Why install internet sockets?

Usually, when connecting the Internet to your computer in the apartment, the master throws long cable, coming from the provider's panel on the staircase. You have to do the laying of it around the apartment yourself and it is not always aesthetically pleasing. As a rule, we just throw it somewhere behind the closet or, as a last resort, put it in the baseboard. This is if we are talking about one computer, but what if you want to connect several devices to the Internet via cable at once - computers, TV? Then you will have to surround the entire apartment with cables, which will completely ruin appearance. Therefore, it is best to foresee this possibility in advance during the next renovation and make hidden wiring of Internet cables, running them inside the walls, and in each room make an exit in the form of a special RJ-45 socket.

Typically the router has 4 outputs for connecting cables local network, respectively, lay 4 cables into the rooms, and bring their other ends to one place, next to the front door, where you can easily hang the router and connect the cables crimped with a connector to the LAN connectors of the router. And the cable from the provider, when connecting the Internet itself, can also be stretched literally a few centimeters to the place where the router is attached - very convenient, practical and aesthetically pleasing.

Pinout of RJ 45 Legrand socket

But in order to implement such a scheme, you need to connect those ends of the cables that go outside in the room to a special Internet outlet into which a patch cord will be plugged in to connect to the computer. I will tell you using the example of the popular Legrand model, a well-known manufacturer of various small items for repairing indoor wiring. This is how it looks externally when assembled and already installed on the wall.

And here it is - disassembled.

To connect cables to it, you must first remove the braid and disconnect the twisted pairs from each other. At the same time, be careful not to damage the cables; they are very thin and easily break even with a small cut. After this, we take the socket and turn the latch so that the top cover to which this latch is attached is removed.

Legrand socket connection diagram (RJ-45)

How to do this is clearly shown in the manufacturer’s official diagram. Just before doing this, pay attention to how the colors of the wires are located in relation to the base mount, so that later, when installing it in place, you do not put this box upside down and thereby confuse the cables. In the model I am describing, the blue color is directed towards that part of the base of the rosette that is located on the “elevation”, and the brown color is on the lower part.

After it was removed top part We insert our network cable from the side of the white latch - so that the braid goes inside it to prevent the colored wires from bending. Now let's look carefully at this little gray box. It has special grooves for these cables, and on the outside there are color and numerical designations indicating which wire should be fixed in which color. Confusion for beginners is caused by the fact that in these color designations the manufacturer tried to combine both type “A” and type “B”. Both of these types with color numbering are demonstrated in the instruction picture above. So, it will be easier to navigate by matching the wire numbers marked on the connector with the cell numbers on this box for crimping the socket.

In this case, you need to choose exactly the type with which the opposite ends of the cables with connectors that will be connected to the router were or will be crimped, that is, both ends must have the same crimp type - either A or B.

We decided on the type and after that we arrange the colors according to the numbers on the socket. I would like to point out that there was an error in the official instructions - in the picture, brown and white-brown are reversed in relation to the actual color of the socket.

Next, we take the box with the inserted wires and easily place it on the base of the mount - while remembering that the blue colors look towards the elevation. And we tighten the latch until it clicks - at the same time, sharp contact plates cut through the braid and the wires are connected to the contact cores on the external connector of the socket. It should be noted here that this does not always happen correctly - I had cases when the braid was not cut through and one of the wires did not make contact, as a result of which the connection between the PC and the router did not work.

In order to determine this, you need to “ring” each contact for the passage of an electrical signal between the two ends of the cable. This can be done either using a universal device that is used by all electricians. Or using a special tester for checking Internet connections - I ordered one from China and showed it to you in a video review. In this case, to connect an outlet to the device, use a known working patch code, for example, which came with the router.

If everything works, then you can fix the RJ-45 Internet socket in the socket box and install an external decorative frame. That's it - turns out it's not that difficult. For starters, watch a video on how to test the performance of cables.

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 a 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 is a combined 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 overhead socket rj-45 is widely used in offices and premises where a large number of wires and their external laying in boxes and mini-channels is appropriate.

Sockets can be multi-port or single-port. Two or more ports will allow you to connect a larger number of equipment, so 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. It is necessary 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 twisted pair 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 the upper part of the socket. 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.

To connect a phone or computer to the Internet information network, the most popular device is the rj-45 socket. However, its installation is not too difficult and can be done independently. However, in order to correctly carry out all the installation work of this device, you must have an understanding of its design and installation procedure.

Registered Jack or RJ is a standard that describes the internal workings of both a plug and a receptacle. On the Internet you can often find the name RG, but the same thing is meant.

Design rj-45

Like other types of computer sockets, rg-45 can be built-in or external. Each of these designs has its own advantages and disadvantages. The advantage of internal installation of such devices is their compactness and hidden cable routing. In addition, these products are more protected from mechanical influences.

As for the disadvantages, the internal installation of the rj-45 socket requires large-scale repair work and does not provide for the possibility of it if such a need arises.

Today, overhead sockets rj-45 cat 5e are the most widely used.

In addition to the installation method, such products can be classified according to the number of consumers connected to them. There are models designed to connect one, two or more wires. Depending on the general scheme For connections, through-type and single-sided sockets are used.

Installing a rj-45 computer socket

It should immediately be noted that products of this type are installed to ensure the operation of low-current electrical circuits. Therefore, working with them does not pose a danger to life and health.

To connect a computer to such a device, you may need a special tool for crimping contacts.

Installation Guide

Work on installing the rj-45 socket is carried out in the following sequence:

• The cable is being laid and the installation box is being installed. All these operations must be done in exactly the same way as when installing a regular electrical outlet. Particular attention should be paid to ensuring that the network cable is reliably protected from mechanical damage.
• If a surface-mounted computer socket is installed, then staples or screws must be used. The cable is laid in special protective boxes.
• Connecting wires. The mentioned connection standards (T568B or T568A) do not pose any difficulty in their technical implementation and differ from each other only in the order of connecting the conductors. You can determine by what scheme they need to be connected simply by looking at how the contacts on the Ethernet plug are crimped on the side of the router that is used to access the Internet.

• In order to make a connection, the twisted pair must be freed from insulation by 2-3 cm, and the conductive wires by 0.5 cm. Each terminal has a color and digital marking that corresponds to a specific wire. Using this marking, you must insert each twisted pair wire into its corresponding socket.

• In some models, there is no need to pre-stripe the wires, since the required connection quality is ensured by the socket mechanism itself.
• Rj45 with connected wires is fixed in, after which the front cover is installed.

If any problems arise when you subsequently connect your computer to the Internet through such an outlet, you should check that the wires are connected correctly to the contact terminals.

Although wireless communications are developing quite quickly, the UTP socket is still in great demand. After all, this product is a mandatory element in the structured cabling system of a modern building. The socket itself is referred to among experts as RJ-45; its versatility allows you to connect UTP twisted pair cables without unnecessary devices. Moreover, you can install such a unit yourself.

Short description

Externally, the RJ-45 computer socket most closely resembles a standard RJ-11 telephone device. The main difference between these two devices is that the number of connector pins has been reduced from eight to four. Therefore, a computer socket can also be used for a telephone, but not vice versa.

Depending on the model, the final unit may differ from its analogues in small characteristics, but the entire design concept remains the same. Professionals say that The quality of an outlet is determined by three main points:

It is the exact number of ports that is considered the main indicator of such a device. Most often there are no more than four. If the user plans to connect many more devices, then he will need an additional patch panel. It is worth noting that the purchase of such a device can only indicate that the master did not provide for all the nuances at the stage of network wiring.

A large number of installed patch cords can cause a lot of inconvenience. For high-quality arrangement of a home or office LAN, you can use two-unit modules.

The installation method of this switching unit depends on the version of the socket. Experts have provided two proven methods:

1. For indoor installation.
2. Outdoor installation.

The choice of one option or another depends on the method of laying the LAN cable. If it is external (for example: the wire is placed in special boxes), then only external sockets will be useful in the work. If the master chose hidden wiring, then the internal fixtures will look more impressive and neat.

It is especially worth noting that power socket RJ-45 is sometimes installed directly on the box itself. IN technically such performance can be considered both external and internal. In addition, the performance characteristics are completely independent of the design of the LAN.

The fact which category it belongs to depends on the characteristics of the cable. Its demand is due to its wide bandwidth, since this indicator affects the data transfer speed, as well as the possibility of using special high-quality Internet technologies. Craftsmen always have a table for this case, which clearly shows the relationship between the category of the outlet and the bandwidth.

Development of modern information technologies influenced by the fact that during LAN installation, cables lower than UTP 5e are practically never used anywhere. To ensure that the result of the manipulations fully meets all expectations, it is necessary that the category of the outlet be no less than that of the wire connected to it. IN otherwise there is a high probability that the data transfer speed will be reduced several times.

Design Features

The professional connection of an RJ-45 socket may differ in external or internal type. Each option has its own advantages and disadvantages. The main positive characteristics of internal installation include compactness and hidden cable routing. In addition, the product itself will be reliably protected from any mechanical influences.

There are practically no disadvantages to the internal installation, the only thing is that if necessary, the user will not be able to move the outlet to another location, and the installation process itself is always accompanied by certain repair work. In this regard, the most popular today are overhead models R-45 cat 5e.

The modification of each device differs in the total number of connected users. Each model is designed to connect one, two or more wires. Depending on the chosen installation scheme, the master can use both single-sided and pass-through sockets.

Pinout principle

A high-quality connection of a twisted pair cable to an outlet is only possible if the technician correctly pinouts the wires. There should be no problems with this task, since opposite each contact group the manufacturers have provided special color markings that fully comply with all established standards. Regardless of which option the master decides to use, the main task so that it is the same type for the LAN. Otherwise, certain problems may arise.

Many people believe that in Russia everyone “crimps” the wire according to the T568 V type, but this statement is very conditional. It's easiest when the user knows which standard his provider uses. You can determine this yourself by looking at the pinout of the connector that is installed on the cable introduced into the apartment.

Connector crimping instructions

You need to start by choosing professional tools that will be useful for installing twisted pair sockets. Certainly, It's better to buy a quality extractor, which allows you to quickly press in and cut off the remainder of the unnecessary wire with one touch of your hand. The Chinese equivalent of such a tool costs about $5. Advertised models can cost three or even five times more.

The extractor is equipped with a universal mechanism that allows you to quickly and efficiently press the wire between two contact knives, cutting off all excess. In addition to this, the unit is equipped with a flat-head screwdriver and a small hook, which is designed to carefully remove the wire if it is improperly terminated.

During work, universal pliers will definitely come in handy for carefully removing the insulating layer. Their cost is almost the same as that of the extractor. This tool works great with UTP, FTP, STP cables. In addition, the user can independently adjust the depth of the cut. Experts do not recommend using a regular kitchen knife to remove insulation, as the risk of damage to one of the wires increases significantly.

When the selection of tools is completed, you can safely proceed to the main algorithm for embedding a twisted pair cable into a switching device. The example will be given based on the assumption that the main cable has already been laid and the outlet space has been prepared. The action plan is as follows:

It is worth noting that you can meet masters who recommend using instead professional tool an ordinary stationery knife. This method is only permissible when you urgently need access to the Internet, but there is no extractor available. But at the first opportunity, such a socket will need to be clamped, since the contact of the wire with the latch will still be broken.

When the twisted pair is pressed in, the module must be installed in its original place. If the socket is of an external configuration, then its base must be screwed to a pre-prepared platform. As a result, the cable should be routed from above, and the connector along the contour from below. If the socket is internal, then its base is mounted in a special glass and then fixed.

All that remains is to screw on the front panel and check the functionality of the device. This can be done with a professional tester, but it is much easier to connect a computer. If there is no network connection, then the first thing you should do is check the pinout is correct, since in 99% of all cases this is the problem.

Installation of a hidden socket

Novice craftsmen often have difficulties with how to properly disassemble such a computer device. While connecting all the conductors, it is necessary to gradually get to the main part - a small case (most often plastic or ceramic), where miniature contacts are located. It is to this plate that all conductors are connected, and then the housing is assembled. The whole point is that different manufacturers this procedure is carried out in different ways.

For example, the well-known brand Legrand produces sockets in which the main connectors are hidden behind the front cover. Having removed this part, the master comes across a white plastic impeller, which contains a small arrow. The impeller must be carefully turned in the direction of the arrow, after which access to the housing and contact plate will open. It is on it that multi-colored conductor markings are applied. The final connection is practically no different from a standard socket, the only thing is that initially you need to thread a twisted pair into the hole on the plate, and only then align the wires.

No less popular today is the Lezard brand, which produces computer sockets using a different design. The metal frame and front panel are fixed with small bolts that can be easily unscrewed. The main internal contact plate is secured with special clamps. When assembling and disassembling such sockets, you need to know that some contacts can only be pressed out with a screwdriver.

But to remove contact group from the housing, you must carefully press on the top latch. After these manipulations, the master will have a small box in his hands. To connect the twisted pair, you must remove the plastic cover that presses the conductors. Since the plastic in this place is quite elastic, the effort must be significant. All that remains is to separate the wires according to the markings applied on the product.

When it is decided to use a shielded cable, then you need to select the appropriate socket, where the connection of such a product is pre-provisioned. Otherwise, the screen will turn into a huge antenna, which will negatively affect the bandwidth and speed of the Internet. It is for this same reason that you should not buy an FTP cable if it is not intended to connect powerful ungrounded equipment.

To fully use high-quality LAN technologies based on twisted pair, it is necessary to equip entire lines. Twisting and soldering in this case are simply unacceptable, as this is fraught with serious losses in speed. In cases where there is a need to extend a certain section of cable, you need to use only special connectors. This device is presented in the form of a small box in which a powerful board with two RJ-45 connectors is mounted. Some models may have twisted-pair latches, like sockets.

You should not buy products from big amount ports for domestic use. Numerous patch cords that are installed in one place will certainly begin to get tangled, causing users some discomfort. It is best to make several outlets at different distances.

The network connection of computer devices is carried out using an RJ-45 socket with two or one port; the socket body material is usually made of impact-resistant plastic (ABS UL 94V-0).

The computer socket is used to connect equipment on one side, and on the other side it functions as a connection to the patch panel (For example, patch panel 19, 1U, 48 ports Ripo).
Types of RJ-45 overhead computer socket devices
Each RJ 45 (8P8C) socket is equipped with 8 contacts. Models are divided into several types and, depending on this, are used at various objects.

Buyers can buy the following options:

Model RJ-45 Cat5 (8P8C). The socket is used to form network structures of the 100BASE-TX standard, providing an information transfer speed of 100 Mbit/s. For example ()
- Model RJ-45 Cat5e (8P8C). This model computer socket is the most popular and allows you to organize a network operating at a frequency of 125 MHz. When connecting a double pair, the speed is 100 Mbit/s. If the number of pairs is 4, the speed reaches - 1000 Mbit/s;
- Model RJ-45 Cat6. The socket is used in work with network protocols Fast Ethernet, Gigabit Ethernet. The high-speed transmission level is 1 Gbit/s;
- Model RJ-45 Cat6A. Analogue previous version with the exception of increased bandwidth, the data transfer rate here is 10 Gbit/s.
Along with the specified parameters, the product is distinguished by the type of installation. There is an internal method, when the devices are mounted in an existing box or delivery note. In the latter case, a box is initially installed and already functioning computer sockets are inserted into it.
When purchasing an RJ-45 computer socket, the future owner specifies the number of ports: 1 or 2. There are different versions, allowing you to connect an RJ-45 or RJ-11 connector.
RJ 45 computer socket components
Installation of products requires prior purchase of components.

One of them is RJ-45 Jack (connector). This is the name of the device connecting the LAN cable and the computer socket. RJ 45 models use 8-pin RJ-45 plugs. determined by the materials used in production.
The second LAN cable is used to connect sockets; the twisted pair is also divided into various models. The choice primarily depends on the type of computer outlet, according to which the twisted pair is selected.

The range of twisted pair cables is:

FTP4 cable number of twisted pairs of conductors: 4/2, category 5e, used for RJ45 cat.5e FTP models with a data transfer rate of 100 Mbit/s. An example is FTP 4 RIPO CAT 5E 24 AWG Cu;

Unshielded twisted pair UTP4 (4-pair, category 6), used to connect RJ45 cat.6 UTP socket models with a data transfer rate of 1GB/sec. For example RIPO.
If it is necessary to connect a large number of devices, an RJ 45 patch panel is purchased, which is installed in racks or telecommunication cabinets 19. It has a significant number (12-50 pcs.) of RJ-45 connectors and pays for its cost many times over. In offices and organizations, it is recommended to use a category 5e patch panel.
If during installation the length of the LAN cable turns out to be insufficient, you can use a 2x RJ 45 pass-through adapter. It easily connects twisted pair cables without loss of signal and transmission speed.

At AVS-Electronics you can buy a computer socket at competitive prices, and also get competent advice on SCS elements and other products.
