Abstract
A high voltage (HV) interface housing is provided that includes an assembly of levers within the housing that detect whether or not the HV lines are coupled to the interface housing. If the HV lines are not in place, the lever assembly prevents the interface cover from being fully installed onto the interface housing, thereby preventing the HV interlock loop switch from being closed. As a result, when the HV cables are not in place, the HV interlock loop switch prevents power from being applied to the HV circuit. If, however, the HV lines are properly positioned within the interface housing, the levers of the lever assembly automatically retract, thus allowing the interface cover to be fully installed onto the interface housing. In this state, the interface cover closes the HV interlock loop switch, thus closing the HV interlock loop and allowing power to be applied to the HV circuit.
