ABSTRACT:
There is disclosed a safety electrical outlet which is provided with a sliding, protective plate that overlies the prong-receiving slots of the outlet and is spring-biased to an offset position barring direct access to receiving slots. The invention is particularly adapted for cube taps of electrical connecting cords which generally comprise bodies of molded plastics in which are embedded parallel conductor strips having prong contactors such as prong-receiving slits which are aligned with the prong-receiving slots of the body. As applied to this construction, all, or all except one, of the pairs of prong-receiving slots are protected by an overlying plate. The protective and overlying plate bears a pair of prong-receiving, parallel, through slots and resilient means in the form of a bifurcated spring member having one leg attached to the plate and its bight and remaining leg seated within a central cavity of the cube tap. The plate and spring can be a one-piece, molded construction of a suitable fatigue-resistant plastic or the spring can be a separate metallic element.
