RJ45 is a kind of connector in the wiring system (ie, communication terminal). The connector is made up of plug (connector, crystal head) and socket (module) with 8 grooves and 8 contacts. RJ is the abbreviation of Registered Jack, meaning "registered socket". In the FCC (US Federal Communications Commission standards and regulations) RJ is a description of the public telecommunications network interface, the computer network RJ45 is a standard 8-bit modular interface commonly known.

RJ45 consists of plugs and sockets, the two components of the connector is connected between the wires to achieve the electrical continuity of the wire.

The core of the RJ45 module is a modular jack. The gold-plated wire or socket hole can be maintained in a stable and reliable electrical connection with the modular socket shrapnel. Due to the friction between the shrapnel and the jack, the electrical contact is further reinforced with the insertion of the plug. The jack body design uses the overall locking mechanism, so that when the modular plug is inserted, the plug and jack interface can produce the maximum pull strength. RJ45 module on the wiring module through the "U" -type connection to connect the twisted pair, locking shrapnel can be in the panel and other information on the device to open the RJ45 module
