Abstract: An electric connector, a plug-in module thereof and a production method of the plug-in module are provided. The plug-in module comprises a base, an input unit, an output unit and an output end. The base comprises a top plate, a bottom plate and one connection plate. A plurality of input terminals and a plurality of intermediate terminals are fixed to the base. The input unit comprises one input circuit board provided vertically to the base and electrically coupled to an end portion of the input terminals. At least one channel are provided on the input circuit board. Each channel comprises a transformer electrically coupled to the input circuit board. The output unit comprises an output circuit board horizontally provided to the base and electrically coupled to the input circuit board via the intermediate terminals. The output end are fixed to and electrically coupled to the output circuit board.

Abstract: The disclosure provides an electrical connector and a communication device. The electrical connector includes an insulator, on which at least one docking socket and at least one module socket are provided; a housing provided outside the insulator; a plug-in module provided on the insulator; and a signal display unit, which comprises a signal display circuit board, at least one SMD (surface-mounted-device) LED electrically coupled to the signal display circuit board, and at least two connection terminals electrically coupled to the signal display circuit board used to transmit signal of the signal display unit.

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: A magnetic passive component and a method for manufacturing the same are provided. The magnetic passive component comprises a magnetic core, a metal-wire-layer winding around the surface of the magnetic core, and an insulating layer provided between the magnetic core and the metal-wire-layer. The material of the insulating layer is a kind of insulating material containing additive of metal ions. To form the metal-wire layer, a trace of metal-wire layer should be made first in the surface of the insulating layer by laser activation and then adopt electroplating process to form the metal-wire layer so as to finally form a metal winding wire on a surface of the magnetic core. The magnetic passive component and the method for manufacturing the same disclose here can realize a simple process, a low manufacturing cost, an automatic manufacturing and a stable and reliable quality.
