Abstract: The present disclosure discloses an electrical connector and a plug-in module. The plug-in module includes a base, a plurality of input terminals, a plurality of output terminals and a PCB module. The base includes a bottom plate, a front plate and a back plate, and a tongue plate extending from the bottom plate forward beyond the front plate; the plurality of input terminals are fixed to the back plate, and two ends of each of the input terminals extend respectively beyond a top end of the back plate and a bottom end of the bottom plate; the plurality of output terminals are fixed to the tongue plate and the front plate, and two ends of each of the output terminals extend respectively beyond a top end of the front plate and the tongue plate; and the PCB module includes at least one circuit board.

Abstract: The disclosure provides an electrical connector, its manufacturing method, and a communication device. The electrical connector includes an insulator, on which at least one docking socket is provided; a housing provided outside the insulator; a signal processing unit provided in the insulator; and a signal display unit comprising a signal display circuit board, at least one SMD (surface-mounted-device) LED electrically coupled to the signal display circuit board, and at least one connection terminal electrically coupled to an exterior circuit board or the signal processing unit.
