ABSTRACT:
A male plug locking device includes an inner socket body, elongated electrical contact elements disposed on the inner socket body, an outer housing disposed over the inner socket body and electrical contact elements, and locking cam elements disposed between the outer housing and inner socket body. The inner socket body is configured for receiving and engaging contact prongs of a male plug and for providing electrical connections with ends of the conductor wires of an electrical cord. The outer housing is mounted on the inner socket body to undergo movement relative thereto between first and second axially displaced positions. The locking cam elements overlie the electrical contact elements on the inner socket body and the contact prongs of the male plug and are operable for respectively clamping the contact prongs against the electrical contact elements and for releasing the contact prongs from the electrical contact elements in response to movement of the outer housing between the first and second axially displaced positions relative to the inner socket body so as to thereby prevent and permit disconnection of the male plug from the inner socket body.
