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.

Claim (Index 12):
A method of rapidly separating outlet contacts from plug contacts of an electrical plug at a DC electrical outlet, the method comprising the steps of:\n providing a sliding contact assembly comprising a sliding contact structure having a base and a plurality of electrical sliding contacts fixed to the base and defining the outlet contacts; a housing defining an internal chamber with the sliding contact structure being disposed in the housing so as be movable linearly within the chamber; and at least one spring disposed between the housing and a surface of the base, and coupling the housing to a fixed member associated with the electrical outlet ensuring that the housing remains stationary and that the sliding contacts are accessible to the plug contacts, so that 1) when the plug contacts are engaged with the associated sliding contacts causing friction there-between, the at least one spring is constructed and arranged to bias the sliding contact structure to engage an internal bottom surface of the housing, 2) when the plug contacts are being disconnected from the associated sliding contacts with friction there-between remaining, the at least one spring is constructed and arranged to compress and store energy, and 3) when the plug contacts are completely disconnected from the associated sliding contacts with no friction there-between, the compressed spring is constructed arranged to rapidly force the sliding contacts away from the plug contacts, reducing arcing energy there-between.
