<p>A cover plate of a power supply socket having an anti-tracking function and capable of being equipped with the terminals of various communication signal lines, an adapter for connecting a power supply plug to a socket employing that cover plate, and a power supply plug. In the cover plate for a power supply socket, an annular fitting groove recessed from the surface is formed around an opening provided to expose the power supply socket body, and a groove part terminal connected with a communication line is provided on the inner wall of the fitting groove. When the fitting ridges of the adapter and the power supply plug are fitted in the fitting groove, tracking is prevented by preventing intrusion of dust. Furthermore, a communication line is connected with an apparatus through the power supply plug when a ridge terminal provided at the fitting ridge is connected with the groove terminal.</p> |
