Abstract (en)
[origin: WO9300726A1] An electrical plug having an extended head portion (13) for insertion into a recessed socket (11) in the mating receptacle includes axial friction ribs (21, 22, 23, 24) at the outer periphery to engage the inner surface of the recessed socket and provide positive frictional forces retaining the plug in the socket. A bevel (35) on the face of the extended head portion facilitates insertion of the head into the recessed socket while a flat, low profile exterior portion (12) of the plug with the electrical cord exiting parallel to the wall further minimizes the accidental dislodgement of the plug from the socket. Expansion slots (25-26, 27-28, 29-30 and 31-32) on either side of the friction ribs allow the friction ribs to expand upon insertion of the head portion into the recessed socket.
