ABSTRACT:
A safety electrical socket includes front and rear insulative bodies which are connected to one another and a receptacle body. The front insulative body has a through bore which has a first section of a smaller diameter and a second section. The rear insulative body has a cavity which is concentric with the second section of the through bore. The cavity has two opposed, narrower side walls which have two contacts connected to an electrical power source. The receptacle body has front and rear portions and an annular flange formed between the front and rear portions. The receptacle body is movable axially in the through bore to enable the rear portion to extend into or retract from the cavity. A pair of elongated conductors are pivoted respectively to two opposite wider sides of the rear portion. When a pair of contact blades are inserted into the socket openings in the front portion and the axial grooves in the wider sides and when the rear portion which extends into the cavity is rotated by a predetermined angle, the conductors can be depressed by the contacts of the rear insulative body in order to engage the contact blades. The conductors disengage from the contact blades and the contacts by means of biasing members when the receptacle body is further rotated by the predetermined angle in a reverse direction.
