ABSTRACT:
An electric outlet assembly includes a receptacle plate having an opening and an inner surface when secured to a flat surface; first and second U-shaped blocks positioned adjacent the opening at the inner surface for supplying AC current; a ground post positioned in line with the opening at the inner surface for providing a ground contact; and a plug for removably connecting an electric cord to the first and second U-shaped blocks and the ground post. In a first embodiment, the plug includes a flat oval plate having electrical contacts at opposite ends thereof and a connectorpost positioned centrally therein which, when inserted through the opening of the receptacle plate and rotated by 90.degree., provides electrical connection between the electrical contacts and the U-shaped blocks and between the connector post and the ground post. In a second embodiment, first and second conductive racks are slidably mounted within a housing at spaced apart locations and a non-conductive gear mounted on a ground shaft engages the racks for moving the racks into electrical contact through openings in the housing with the U-shaped blocks, with the ground shaft electrically connecting with the ground post.
