Abstract:

The danger associated with an electrical plug partially withdrawn from an electrical outlet to exposed prongs of the plug while in electrical connection is reduced using a safety device comprising a resilient, compressible block of electrical insulating material mounted to a connection side of the plug. The prongs are inserted into passageways in the block that extend from one side of the block to another side of the block. With the block mounted to the plug, the user pushes the prongs into the outlet so the prongs are essentially completely within the outlet and the block is essentially completely compressed. The compressed block expands to cover the exposed, electrically connected plug portions upon partial removal of the prongs from the electrical outlet.
