ABSTRACT:
A locking device for an electrical receptacle to prevent the withdrawal of an inserted male plug includes a magnet in slidable engagement with the receptacle body. An actuator arm moves the magnet between retracted and extended positions. Locking means in the receptacle body for engaging a hole in the blade of the plug is moved by the position of the magnet. When the actuator arm is in the extended position the magnet is positioned proximate the hole of the blade whereby the locking means is engaged with the blade by the force of attraction of the magnet. In one embodiment the actuator arm includes two magnets of opposite polarity and the locking means includes a third magnet. When the actuator arm is moved between extended and retracted positions, the magnets align to either retract or repel the locking means.
