Design features and pinout of RJ-45 sockets

RJ 45 sockets are devices that differ from classic power outlets by the presence of twisted pair. Such devices are also called internet outlets. They are an indispensable element of the cable system in modern homes. Installing an outlet does not cause any difficulties even for a beginner, but you need to consider a number of nuances when connecting.

Design Features

Elements of an external outlet RJ-45

There are various modifications of Internet outlets on the market. Regardless of the model, the device has the following structural elements:

  • decorative cover;
  • base;
  • chip;
  • twisted pair convectors;
  • cable tie to secure the wire;
  • connector.

Modern models with increased functionality may have other details in the design.

Externally, the rg45 socket is similar to a telephone. Their main visual difference is the number of connectors - an Internet outlet has 8 connectors, while a telephone device has only 4.

Types and specifications

Overhead and external RJ-45 sockets

The parameters of the outlet depend on the following aspects:

  • number of ports
  • housing design;
  • category.

Most often, models with the number of ports from 1 to 4 are used. There is a possibility of increasing the number by using a patch panel. But in practice this is almost never applied, since it is inconvenient to use several contacts. Single-port and dual-port models are used for installation in homes and office premises.

The performance does not affect the technical characteristics and circuit diagram of the device, this is just a way to classify the device by type of installation. Allocate external and internal sockets. The choice of a particular installation method depends on the type of wiring in the house. The socket rj 45 waybill is used for open type of wiring. It is easy to install and does not require wall chipping. The internal model will need to be built into the walls. Sockets that are mounted in a box are allocated in a separate category. They are both wall and interior.

The category of the outlet directly depends on the parameters of the cable used. The data transfer speed, the ability to use the latest network technologies - all this affects the technical characteristics of the Internet outlet. The dependence of the parameters of the device on the characteristics and category of cable can be found in special tables.

Models with a designation below 5e are almost never used. When choosing, it is important to consider that the category of the outlet should not be lower than the category of cable. Otherwise, there is a risk of lowering the data transfer rate.

Outlet pinout

Pinout RJ-45

The information socket rj 45 is convenient in that its pinout is written on the device itself next to the contact group. There are 2 marking standards - T568A, T568B. They are also called direct and cross. Direct pinout is used to connect the end consumer (for example, laptop, TV) with a router. Cross-pinout is used to connect two devices with similar functionality. Their difference is in the connection of pins - in direct colors coincide with each other, and in the cross TX and RX are interchanged.

During installation, you should know in advance which pinout is used indoors. Violation of local area network standards threatens connection failure. You can find out the standard used in the house by the provider's cable connector.

Connecting an RJ 45 outlet

Before you begin installation and connection, you need to choose the right tools. To facilitate installation, there is a special device for termination on twisted pair.This is a versatile extractor that cuts off the remains of the wire and extrudes the cable. If the wire was not installed correctly, the extractor has a screwdriver and a hook with which you can get the cable and repeat the installation. You will also need a device for stripping insulation. Using a stationery knife is not recommended - there is a high risk of core damage.

Scheme of connecting an Internet outlet

 

Before starting the installation, you need to prepare the seat and lay the wires. Then you need to follow the algorithm below:

  1. Strip the ends of the cable 4-5 mm. If the cores are damaged, they should be cut and carefully cleaned again.
  2. Level the pairs of cores.
  3. Disassemble the power socket by removing the front panel from it. It is usually fastened with fixing screws. The clamps may be different, it all depends on the design. The fixing method can be found in the instructions.
  4. Secure the wires with a special cable tie.
  5. Install the cables in the retainer, observing the necessary marking.
  6. Press in and remove excess cable parts with an extractor. Pressing must be carried out by a professional device, otherwise contact may be lost. When buying an outlet, you need to pay attention to its components. Large manufacturers often put the simplest extractor in a kit for the device.
  7. Installing the module in place.
  8. Fixing the front panel.

The final step will be to verify the health of the assembled system. You can test the socket using a special tester, or by connecting to a computer and checking the connection.

Useful Tips

STP and FTP cables are used in equipment with grounding

There are special types of cables - shielded. Such wires need to be connected to a wall outlet. If you use a regular Internet outlet, the data transfer speed will drop. For the same reason, you cannot use STP and FTP cables for equipment without grounding.

In a local area network, you can not use extension wires using twisting. This method is unreliable. The best way to build cables is through special connectors.

In everyday life, it is better not to use devices with more than two ports. This is inconvenient to use and leads to tangled wires. It is recommended to install several outlets in different frequent rooms. You can also put an external double socket rj 45.

Main mistakes

Twisting of twisted pair more than 13 mm is not allowed

Installing the rg 45 outlet is straightforward if done carefully. But there are a number of mistakes that experts make more often than others.

  • Non-compliance with connection standards. If the device does not work and there are problems, you need to check the compliance with the marking. This is the most common error, it solves about 90% of connection problems.
  • Cutting the cores before closing the lid. If you cut off the excess parts before the cover has been installed, the wires may fall out. In this case, you will have to perform the installation procedure again.
  • Stripping insulation more than 13 mm. Large uninsulated parts of cores lead to a drop in transmission speed and a deterioration in signal quality.

Installing an Internet outlet on your own is easy. It is only important to follow the instructions for connecting, follow all the steps carefully and carefully.
