Abstract
The invention is a lock for male electrical connectors used with appliances and power equipment and consists of a housing with receiving slots for the connector prongs and a U-shaped spring in the housing containing nibs that engage the apertures on the connector prongs. A spring biased plunger engages the arms and cause them to release the prongs when depressed. Cooperating holes through the housing and the plunger allow a lock to pass through and disable the plunger. The spring biasing the plunger is selectibly changeable for situations where a stronger spring would negate the use of a lock. The housing is sufficiently thin that a three conductor plug could be locked without interference from the ground prong.
