ABSTRACT:
A shockproof electrical wall receptacle comprises resilient ends of electrically conductive material extending from ends of two electrically conductive circuit members in the box in spaced angular relation with each other in a generally V shape and positioned between the prongs of an electrical connector plug inserted in the box and spaced therefrom. A housing of rectangular parallelepiped configuration is movably mounted in the opening in the box for selective insertion into the box flush with the wall side of the box and extension therefrom. The housing has a pair of spaced slots formed therein for accommodating the prongs of an electrical connector plug. A plunger is affixed to the housing and extends through the opening through the wall side for movement in axial directions. The plunger has a head of electrically insulative material at an end in the box in proximity with the resilient end of the circuit members equidistantly spaced therefrom and therebetween. In the absence of an electrical connector plug in the receptacle, the housing extends from the box and the plunger is spaced from the resilient ends of the circuit members and the circuit members are maintained in open circuit relation although an electrically conductive object inserted into the box via either slot in the housing does not contact one of them. When an electrical connector plug is inserted in the housing, the housing is moved into the receptacle and the housing moves the plunger further into the box so that the head of the plunger abuts the resilient ends of the circuit members and moves the ends farther apart into electrical contact with the corresponding prongs of the electrical connector plug thereby closing the circuit of the circuit members via conductors connected to the prongs via the plug.
