TWIST-LOCK CONNECTOR FOR ELECTRICAL PLUG AND WALL SOCKET.

摘要

A twist-lock connector assembly for securing an engaged electrical plug to an electrical socket (or outlet) that includes a rotatable cylindrical sleeve disposed enclosing an electrical plug. In use, the electrical plug is inserted into the socket and the cylindrical sleeve is rotated about a 1/4 turn. This causes the inner disposed nubs of the sleeve to lockingly engage the outer disposed threads of the upstanding cylindrical wall of the cover plate. This prevents the electrical plug from being accidentally pulled loose from the socket. One aspect of the twist-lock connector assembly provides securing engagement of an electrical plug to a female socket portion of an extension cord. The female socket is enclosed by a retractable sleeve provided with engaging nubs adapted to lockingly engage the external threads of the rotatable sleeve of the electrical plug. Another aspect of the twist-lock connector assembly provides rapid twist-locking connection between a female connector of an extension cord and the male connector end of a whip end of handle portion of an outdoor power tool.
