How is the RJ45 connector connected?

The RJ45 connector is used for terminating the data cable to realize the connection and change of the device and the patch panel module. The RJ45 crystal head is required to have good conduction performance; the contact trigeminal reed has a gold plating thickness of 50μm, which satisfies the super 5 transmission standard and conforms to the T568A and T568B line sequences; and has the functions of preventing looseness, plugging, and self-locking.

The RJ45 connector is a standard connector in copper cabling that together with the socket (RJ45 module) form a complete connector unit. A connector consisting of these two components is connected between the wires to achieve electrical continuity of the wires. It is also an integral part of the integrated wiring technology finished jumper, and the RJ45 crystal head is usually attached to both ends of the twisted pair cable. In the standard integrated wiring design and installation, this accessory product is usually not listed separately, that is, the user does not claim to complete the connection between the twisted pair and the RJ45 plug.

RJ45 connectors are available in both unshielded and shielded versions. The shielded RJ45 plug is covered with a shielded cladding, and the physical shape is the same as the unshielded plug. There is also an industrial shielded RJ45 plug specifically designed for the factory environment, used in conjunction with the shield module.

RJ45 connectors often use a non-slip plug jacket to protect the plug, slide and easy to insert and remove. In addition, it has a variety of color options that can be provided in the same color as the embedded icon for proper connection.

Wire sequence connection
The information module or RJ45 plug and twisted pair are terminated with T568A or T568B. They are supported by TIA/EIA-568-A and TIA/EIA-568-B integrated wiring standards. The RJ45 crystal stylus sequence number should be observed as follows: the front side of the RJ45 plug (the side with the copper needle) facing itself, with the copper needle facing up, one end of the connecting cable facing down, and 8 copper from left to right. The needles are numbered 1 to 8.

The line order from pin 1 to pin 8 is:
T568A: white green, green, white orange, blue, white blue, orange, white brown, brown.
T568B: white orange, orange, white green, blue, white blue, green, white brown, brown.
There is no essential difference between the two international standards, just the difference in color. It should be noted that when connecting two RJ45 crystal heads, it must be ensured that: 1, 2 pairs are a pair, 3 and 6 pairs are a pair. 4, 5 feet are a pair, 7 and 8 pairs are a pair. In the same integrated wiring system project, only one connection standard can be used. TIA/EIA-568-B standards are generally used in the production of connecting lines, sockets, patch panels, etc., otherwise, they should be clearly marked.

The cable needs to be terminated with a similar connection device. For example, connectors of Category 5e and Category 6 are similar in appearance, but differ in physical organization. If a Category 5e cable is terminated with a Category 3 standard connector or distribution panel, the performance of the cable channel is reduced to Class 3. Therefore, in order to ensure the performance of the cable, the module connector must also meet the corresponding standards.
