Abstract: An electric power connection part of an electromagnetic clutch field coil assembly connected with an electric power connector at a side of a vehicle engine, includes a housing assembly connected to the field coil assembly with electric wires, which is extracted therefrom, interposed therebetween; a discharge device for absorbing a surge voltage; and a magnetic field elimination device for eliminating a residual magnetic field are injection molded and combonined within the housing assembly. Accordingly, the electric power connection part has an advantage in that it is not directly influenced by heat radiated from a field coil assembly so that electric/electronic devices can be prevented from being damaged; since an epoxy applying process for attaching electric/electronic devices such as a discharge device and a magnetic field elimination device is omitted, a manufacturing process is greatly simplified; and the number of components are reduced so that manufacturing process thereby decreasing costs.

Abstract: The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. A field coil assembly according to the present invention includes a field coil member 20 having a coil wire 22 extending outward; a power connecting member 30 having a sleeve 35 with a terminal 40 protruding out, the terminal electrically connecting the coil wire 22 to an external power source; a flange 28 coupled to one side of the field coil member 20 with the coil wire 22 drawn therefrom, the flange 28 having a catching portion 29 coupled with the sleeve 35, the flange 28 having electric conductivity; and a ground terminal 50 provided in the sleeve 35 and electrically connected to the terminal 40, the ground terminal 50 having at least a portion contacted with the catching portion 29.

Abstract: The present invention relates to a connector of an electromagnetic clutch for a compressor and a manufacturing method thereof. The method includes the steps of arranging a leading end of a lead wire 62 or 72 of at least one discharge device 60 or remaining magnetic field removing device 70, which configures a surge absorbing circuit, to a terminal 50 installed in a connector 30 configuring a field coil assembly and having a coupling slot 56 formed in one side thereof; plastically deforming at least one slot bridge 57 to fix the lead wire 62 or 72 to the coupling slot 56; and making the connector 30 in a state where the terminal 50 is fixed to an assembly of at least the discharge device 60 or remaining magnetic field removing device 70 by injection molding.
