ABSTRACT:
An improved electrical plug household use to protect household occupants from electrical shocks while inserting or removing the plug from an electrical receptacle. The plug, in general, is a standard household electrical plug with or without a ground prong. The improvement of the present invention is to mount an elastically collapsible electrically insulating hood on the plug surrounding the prongs so that when the improved plug is inserted more than half way into the household electrical receptacle, the extent of the prongs not yet within the receptacle is surrounded by the hood and inaccessible to contact by household occupants, especially children. The hood can be a plastic bellows integrally molded with the body of the plug or the hood can be formed separatly and glued to the body of the plug. The hood can also be a foamed polymer tube section glued to the body of the plug.
