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.
