TRANSMISSION EQUIPMENT FOR POWER LINE COMMUNICATION, OUTLET PLUG, OUTLET PLUG BOX, RECEPTACLE STRIP, COUPLING DEVICE, COMMUNICATION EQUIPMENT, AND COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress emission of leaked radio waves by suppressing a current which flows through a ground capacitor and the ground into a communication signal path, and generates a leaked electric field, without suppressing a communication signal current in PLC communication.;SOLUTION: Transmission equipment for power line communication is constituted so that a magnetic core 401 around which a first wire 402a and a second wire 402b are wound is included, the first wire and the second wire are paired and wound around the magnetic core for a plurality of turns, a relative interval 402abw between the paired first and second wires is equal to a take-out port 402T to the outside, and a direction of a sending signal current isa flowing to the first wire is relatively opposite to a direction of a returning signal current isb flowing to the second wire.;COPYRIGHT: (C)2007,JPO&INPIT
