To connect a phone or computer to the Internet information network, the most popular device is the rj-45 socket. At the same time, its installation is not too complicated and can be done independently. However, in order to correctly perform all the installation work of this device, it is necessary to have an idea of \u200b\u200bits design and installation procedure.
Registered Jack or RJ is a standard that describes the internal structure of both plugs and sockets. On the Internet, you can often also find the name RG, which means the same thing.
rj-45 design
Like other types of computer sockets, rg-45 can be built-in and external. Each of these designs has its own advantages and disadvantages. The advantage of indoor installation of such devices is their compactness and concealed cabling. In addition, these products are more protected from mechanical stress.
As for the disadvantages, the internal installation of the rj-45 socket requires extensive repair work and does not provide for the possibility of it moving to another place when such a need arises.
To date, overhead sockets rj-45 cat 5e are 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 connection scheme, pass-through and one-sided sockets are used.
Installation of a computer socket rj-45
It should be immediately 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.
You may need a special crimping tool to connect your computer to such a device.
A feature of the operation of computer sockets is the almost complete impossibility of repairing them. If the module, which is the main part of the rj-45 cat 5e product, fails, the entire device must be replaced.
It is worth paying attention to the fact that such devices are designed to transfer data at a speed not exceeding 100 Mbps. Therefore, if it becomes necessary to provide a higher Internet speed, for example, in an office, it is not advisable to install them.
Installation of rj-45 occurs according to the algorithm that is used when installing overhead or built-in electrical sockets. The main difference in this case is the connection of such a device to a network cable.
To connect the rj45 cat 5e socket to the network, a cable is used, which is called "twisted pair" and consists of several insulated copper conductors, twisted in pairs and placed in a common plastic sheath.
To connect your computer to the Internet, you must use a cable consisting of 4 pairs of wires. All of them have insulation painted in a strictly defined color. This greatly simplifies the process of connecting the outlet.
Socket connection tools
In order to quickly and efficiently connect such a device, it is necessary to provide the following tool:
- Computer socket.
- Eight-core twisted-pair cable.
- A knife or a special tool designed to remove insulation from wires.
- Perforator (may be needed if the cables have not been laid in the walls and the installation box has not been previously installed).
- Wire crimping device.
- Box for socket installation.
- Screwdriver.
Installation guide
Installation work of the rj-45 socket is carried out in the following sequence:
- Cable laying and junction box installation in progress.All these operations must be done in exactly the same way as when installing a conventional electrical outlet. Particular attention should be paid to ensure that the network cable is reliably protected from mechanical damage.
- If a surface-mounted computer outlet is installed, then brackets or screws must be used. Cable laying in this case is carried out in special protective boxes.
- Wire connection. The mentioned connection standards (T568B or T568A) do not represent any difficulty in their technical implementation and differ only in the order of connecting the conductors. You can determine according to which scheme they need to be connected simply by looking at how the contacts on the Ethernet plug are crimped from the side of the router 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 number 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 for preliminary stripping of wires, since the required quality of the connection is provided by the socket mechanism itself.
- Rj45 with connected wires is fixed in socket boxthen install the front cover.
If any problems arise during the subsequent connection of the computer to the Internet through such an outlet, then you should check that the wires are connected to the contact terminals correctly.
