Abstract
A plug engagement apparatus for engaging and conducting electricity into an electric plug having plug prongs, the prongs having prong free ends with prong openings includes a prong retaining mechanism for receiving and retaining at least one of the plug prongs; and a slide bolt structure including at least one locking bolt and a locking bolt constraining structure for constraining the locking bolt to slide relative to the prong retaining mechanism and into the prong opening in the plug prong, so that the plug prong is engaged against removal from the prong retaining mechanism, and where the locking bolt constraining structure constrains the locking bolt to slide relative to the prong retaining mechanism and out of the prong opening in the plug prong, so that the plug prong is released and removable from the prong retaining mechanism; where the locking bolt constraining structure includes a mounting structure, so that the locking bolt constraining structure constrains the slide bolt structure to slide relative to the face plate, so that the locking bolt slides to enter the prong opening and thus locks the at least one prong within the apparatus.
