  • Patent number: 3982084
    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.
