One shank portion is adapted to extend in a terminal and the other shank portion is adapted for connection to a conductor and extends downwardly from the first shank portion to minimize stress on the latter connection. A notch is formed in the one shank portion to secure the connector in the terminal.

Abstract: A safety plate for electrical outlets includes a cover plate having apertures therein for receiving the prongs of an electrical plug. A pair of slidable panels also having apertures for the prongs of a plug, are mounted to the back of the cover plate, and are held in place by a back plate. The back plate has a pair of holes therethrough corresponding to the receptacles of an electrical wall outlet, so as to allow a close fit between the receptacles and the slidable panels. A spring biases the panels so as to misalign the panel apertures with the cover plate apertures, such that there is no direct opening between the cover plate apertures and the receptacle apertures. A tab projects from each slidable panel through an opening in the side of the cover plate, to allow the user to push each independent panel against the bias of the spring and align the panel apertures with the cover plate apertures, and thereby allow insertion of an electrical plug therethrough into the receptacle apertures.

Abstract: A spring loaded cover for indoor receptacles such as an electrical outlet is provided to prevent damage to the receptacle and electric shock to children resulting from insertion of objects into an electrical receptacle. The cover has a base plate having longitudinal flanges extending from its top surface. A cover plate has longitudinal slots which coact with the flanges of the base plate to allow the cover plate to slide relative to the base plate. Springs force the cover plate to a closed and locked position upon release, or upon removal of a plug from the receptacle. Stops on the cover and base plates limit the travel of the cover plate, and resilient locking device engages the cover plate when in the covered position.

Abstract: New cover assemblies for electrical fixtures in buildings allow conventional outlets and (toggle) light switches to be cheaply converted into a variety of different color designs and/or colors without changing the electrical infrastructure of the fixture. The cover assemblies comprise a cover plate with an appropriate number of orifices, each orifice being covered by a slider so that the whole cover assembly shields the conventional parts of the fixtures normally visible in building interiors.

Abstract: A safety improvement in cover plates for electrical outlets. A cover plate for electrical outlets having sets of a spring-loaded sliding traverse plates which shift to open and close electrical wall outlets used in residential, commercial, and industrial locations. The sliding spring-loaded traverse plates being positioned between sets of tracks which are laterally parallel to outlet holes located in the cover plate, and each traverse plate having a hole which may be manually positioned to be in line with outlet holes located in the cover plate. When holes in the traverse plates and the cover plates are in line, the prongs of male terminals may be inserted into the female recepticle. When the male terminal is removed from the female recepticle, the traverse plates automatically spring into a closed positions thereby shielding the said female recepticle, which thereby prevents a child from being electricuted by sticking a small metal object into female electrical outlets.

Abstract: A protective cover for removable attachment to the open end of an electrical connector that has exposed electrical contacts thereat, includes an insulative body having walls for substantially enclosing the open end of the electrical connector. The body includes a pair of guiding members that are adapted to engage side surface of walls of the electrical connector and guide the installation of the cover onto the connector such that potential damage to the electrical contacts will be minimized or prevented. The dust cover includes a flexible tether preferably integrally attached to the insulative body, the tether terminating in a discontinuous loop. The discontinuous loop has an opening so that the loop may be removably attached to an electrical cable that is terminated to the electrical connector. In the installed condition, the dust cover suitably prevents contaminants, debris or other particles from entering the open end of the connector while the electrical connector is in a disconnected condition.

Abstract: Devices for protecting the bulb of a night light against damage and for denying access to the sockets of an electrical outlet into which the night light is plugged and for also denying access to those parts of the night light which might produce an electrical shock if touched. One component of the protective arrangement is a cover with externally threaded bosses which are apertured so that the night light can be plugged into a socket which a boss overlies by installing the night light through the aperture. The night light includes a bulb surrounding protective shield which is clamped against the boss by a safety cap of the push-and-twist type, thereby protecting the bulb and isolating the socket and electrically charged parts of the night light. Safety caps are also used to deny access to any othe sockets of the outlet servicing the night light, and these safety caps may be designed so that they will perform this function when the protected socket is in use as well as when it is out of service.

Abstract: A protective cover for restricting access to the female sockets or connectors of an electrical outlet, thereby protecting infants and small children and others of limited understanding against electrical shock. The cover includes a base plate bearing an externally threaded boss which replaces the conventional outlet cover; a safety cap of the push-and-twist type threaded on the boss; protective members which are clamped by the safety cap against the boss overlying the socket being protected to deny access to the socket, both when the socket is in use and when it is not in service; and a platelike shield which normally overlies, and denies access to, a second female socket of the typical double socket wall outlet. This shield can be swung aside after backing off the safety cap to furnish unprotected, but controlled, and typically temporary, access to that second female socket.

Abstract: A wall cover plate assembly having a face plate defining electrical plug receiving openings. A guide on the rear side of the face plate slidably confines independent closures each of which is biased to a closed portion by a tensioned member. The guide also defines openings through which the electrical plugs may be inserted. A modified form of cover plate assembly provides for securement of the guide by means of a mortise and tenon joint. A barrier overlying the rear side of the cover plate blocks air and sound from entering a room via an electrical outlet. Recessed closures also inhibit air and sound passage.
