RJ45 socket has many applications. In 2014, the global output of rj45 sockets reached 62 billion, the market size reached 61.5 billion yuan, and the average annual growth rate will be 16% and 13% respectively.

Note 1: The grounding terminal (protective terminal) of RJ45 socket shall not be directly connected with the working zero line terminal.

Notes II. The upper hole of three-phase four hole socket and three-phase five hole socket is a protective terminal, which should be connected with the grounding wire or protective zero line; For three-phase sockets in the same place, the phase sequence of their wiring must be consistent with that of the plugs of electrical equipment.

Note 3. In damp or dusty places, well sealed waterproof and splash proof sockets should be selected. The socket must be firmly installed, and there must be no exposed metal parts on the panel. The conductor current carrying capacity of the socket shall match the rated current of the socket.

Note 4: When AC, DC or sockets with different voltage levels are installed in the same place, there should be obvious differences, and sockets with different structures, different specifications and sockets that cannot make plugs interchangeable must be selected; The matched plugs shall be used according to AC, DC or different voltage levels.

Precautions 5. Two hole socket, the right hole or upper hole facing the socket is connected to the phase line, and the left hole or lower hole is connected to the neutral line; For single-phase three hole socket, the right hole facing the socket is connected to the phase line, the left hole is connected to the working zero line, and the upper hole (protective terminal) is connected to the ground wire or protective zero line. The wiring of the socket shall correspond to the socket.

In addition, after the rj45 socket model is selected correctly, pay attention to the size of the outlet aperture at the end of the plug to prevent water leakage when the cable is smaller than the aperture. When selecting RJ45 connector, shielding coating shall be considered to prevent salt spray. RJ45 socket wiring must be terminated according to the corresponding contact serial number. RJ45 socket shall not be powered on before the end is locked.
