ABSTRACT:
A plug safety adapter is provided for preventing electric shock from occurring while handling an electric plug. The plug safety adapter is comprised of a cylindrical housing, a face plate and a spring which extends between the cylindrical housing and the face plate for applying a biasing force therebetween. The face plate and the spring are positioned inside the cylindrical housing, such that the face plate is moveable within the housing against the biasing force of the spring. The face plate has holes of the same size as those of the prongs of the electric plug for receiving the prongs, such that the face plate is secured to the electric plug and moves backward and forward with the electric plug. As the plug is pushed into an electrical outlet, the housing will push rearward of the prongs of the electric plug and rearward of the face plate. The forward end of the face plate will fit substantially flush with the lowermost end of the housing when the electric plug is fully inserted into the electrical outlet. When the electric plug is removed from the electrical outlet, the housing will move forward to extend forward of the face plate and around the prongs of the electric plug. The prongs are constantly shielded by the housing as the electric plug is being pushed into and then later removed from an electrical outlet.
