Abstract
A sliding contact assembly for a DC electrical outlet receives plug contacts of an electrical plug. The assembly includes sliding contact structure having a base and a plurality of electrical sliding contacts fixed to the base. A housing includes a first end wall having an internal top surface and second end wall opposing the first end wall. The second end wall has an internal bottom surface. The housing has a side wall structure defining an internal chamber between the top surface and the bottom surface. The sliding contact structure is disposed in the housing to be movable linearly within the chamber. A spring is disposed between the top surface of the housing and a surface of the base so that when the plug contacts are completely disconnected from the associated sliding contacts, the spring rapidly forces the sliding contacts away from the plug contacts, reducing arcing energy there-between.
