A power plug receptacle having a safety cover comprises a plurality of sockets each provided with a rotary safety cover. A socket and a safety cover are coupled through inserting a pivot post into a pivot hole and engaging a guiding pin into a guiding slot. A torsional spring provided within the socket resiliently ejects the safety cover into a position where the socket holes and the safety cover holes are misaligned. Therefore, the socket is automatically sealed, achieving the protective functions against foreign intrusion.
