Patent ID: 7175463

Claim:
A plug for securing to a socket, the plug comprising: a housing; a plunger movably positioned within and functionally engaged to the housing; at least one prong comprising at least two blades, the at least two blades including an outer blade having a proximal end secured to the housing and a distal end extending outside the housing, and an inner blade having a proximal end positioned within the housing and functionally engaged to the plunger and a distal end extending outside the housing; and a rotatable collar positioned around the housing, the collar functionally engaged to the plunger, wherein rotation of the collar causes movement of the plunger within the housing so as to translate rotation of the collar into selectively applied force to the inner blade of the at least one prong, causing the distal end of the inner blade to move away from the distal end of the outer blade, thereby causing the plug to selectively clamp within the socket.
