CA 2210359

The present invention relates to electrical wiring devices such as electrical receptacles, switches, and the like, and more particularly to wiring devices with a clamp for the ground connections to such devices. The present invention includes a pressure plate which engages the ground plate of a receptacle with legs of a pressure plate disposed within correspondingly shaped recesses adjacent the ground plate of the receptacle, so that the pressure plate is substantially constrained from rotation relative to the groundplate so that a wire can be received between the ground plate and the pressure plate when the screw is backed out a sufficient distance.

Cette invention concerne des dispositifs de câblage électrique tels que prises, commutateurs et appareils analogues et, plus particulièrement, des dispositifs comportant une pince de mise à la terre. La présente invention comporte une plaque de serage qui s'appuie sur le plot de mise à la terre de la prise. Cette plaque comporte des pattes qui s'engagent dans des évidements ménagés à proximité du plot susmentionné et l'empêchent quasi totalement de tourner par rapport audit plot. Ce montage permet d'insérer un conducteur de mise à la terre entre ladite plaque et ledit plot dès que la vis de pression est suffisamment dévissée.
