ABSTRACT:
A safety cover for an electrical wall outlet is described that has a cover base plate and at least one cowl means attached to the base plate to enclose an electrical plug when the plug is in the electrical receptacle. The cover has a rail means in the inside circumferential surface of the cowl to guide the plug into the receptacle and to reduce the sagging of the plug while in the receptacle. This reduces possible accidental contact with the prongs of the plug when it is being inserted or extracted while the prongs of the plug are still in contact with the receptacle which reduces the chance of an electrical shock or a fire hazard. There is a protective cap means to place over the access port to the cowl to reduce the chance of undesired entry to the receptacle while the plug is not in place in the receptacle. There is a locking means on the cover comprising a locking pin on the outside surface of the cowl means and a J-shaped camming slot on the cap. There is a resilient means on the under surface of the top of the cap to encourage a firm locking engagement of the cap to the cowl when it is locked in place.
