ABSTRACT:
Electrical sockets are disclosed, having insulated housings with apertured end walls for receiving the contact blades of an electrical plug. One socket includes transversely spaced first and second contact bars therein capable of limited movement relative to the housing. This socket also includes first means movable between first and second positions for blocking such limited movement when in its first position and allowing such limited movement when in its second position. It further includes second means movable therein for clamping the contact blades and bars against the first means when the latter is in its first position, thereby to lock the contact blades in the housing, the movement of the first means to its second position serving to unclamp the contact blades and bars to allow the blades to be withdrawn from the housing. Another socket includes transversely spaced first and second contact bars positioned therein. This socket includes first and second clamping means positioned adjacent to and outboard of the first and second contact bars, respectively, for clamping the contact blades and bars together, when actuated, to inhibit removal of the contact blades from the housing, and for unclamping the contact blades and bars, when deactuated, to allow removal of the contact blades from the housing. It further comprises camming means coupled to the clamping means for moving the latter between their actuated and deactuated conditions; and, actuating means coupled to the camming means for moving the same between first and second positions, thereby to move the clamping means between its acuated and deactuated conditions.
