Electric power connection part of magnetic clutch field coil assembly
View Patent ↗The present invention relates to an electric power connection part of an electromagnetic cluth field coil assembly coupled with a vehicle compressor. Since the electric power connection part has the discharge device and/or the magnetic field elimination device and the terminal which are integrally formed by injection molding in the housing assembly of a electromagnetic cluth field coil assembly, it is possible to rapidly and facilely perform the assembling process, increase the productivity and also reduce fabricating costs.
