ABSTRACT:
A solenoid unit for use in high amperage environments includes a hollow cup-shaped housing having a closed end and an open end. A contact section is located adjacent to the closed end, and a coil section is located adjacent to the open end. The closed end includes an end wall. First and second power contact terminals each include a threaded member extending exteriorly for receiving a lead clamping nut. Each terminal includes an enlarged mounting head embedded within the end wall, with an inner contact extending from the end wall. Each head includes a circumferential knurled surface to oppose rotational and axial forces and thereby permits high clamping torque forces on the nut. A bridging contact is aligned with the inner contact ends of the terminals and moves axially thereof. The housing includes inwardly extending opposed locating members which define the contact chamber and guide the bridging contact within a free space to cool the contact assembly. The coil assembly is coupled to position the contact between engagement with the contact ends and spaced therefrom.
