PURPOSE: A plug socket is provided to have a cover separately opening/closing plug insertion holes, and to seal an unused plug insertion hole, thereby preventing foreign substances or moisture from incoming. CONSTITUTION: A side wall cover(12) is inserted into a plug socket through a cover piercing hole(13). The cover piercing hole is faced with an upper plug insertion hole on a lower plug insertion hole. When the cover is closed, one end of the cover that is not inserted into a lower side wall forms a cover insertion groove(14) where the side wall and the one end of the cover are inserted, on a part contacted by an upper plate(10) of the plug socket. The cover has various colors with a plastic film. On both ends of the cover, a hooking projector is formed, not to separate the cover or insert the cover into the plug socket.
