ABSTRACT:
A watthour meter socket adapter has a spring loaded jaw-type electrical receptacle adapted to receive a blade-like contact of a watthour meter. The electrical receptacle has a main blade member or bus bar with a terminal end portion thereof forming a first jaw at the end of the receptacle. A jaw member overlies and is rigidly secured to the main blade member, with a terminal end portion thereof forming a second jaw at the end of the receptacle. The overlying main blade member and jaw member having cooperating relatively straight contact faces that face one another on opposite sides of a narrow insertion space for receiving said blade-like contact. A narrow transverse slotted opening extends across a lower portion of the insertion space between the main blade member and the overlying jaw member. A spring member normally applies a spring biasing force to urge the contact faces toward one another for closing the space between them. The spring member comprises a continuous spring wire member of composite configuration in pressure contact with an outside face of the main blade member opposite its contact face, extending along one side of said contact faces, through said slotted opening, along the other side of said contact faces and in pressure contact with an outside face of the jaw member opposite its contact face, the spring member applying an inward biasing force on a blade-like terminal inserted into the insertion space between the contact faces of the jaws.
