ABSTRACT:
A socket safety apparatus includes an upper cover, a lower cover, a cover body, and a flexible element. The upper cover has two first plug holes. The lower cover is located below the upper cover and has two second plug holes that correspond to the first plug holes. The cover body, movably located between the upper cover and the lower cover, is supported above the lower cover via a supporting portion so that two sides of the cover body can move upwards and downwards. The cover body has two slant surfaces and two braking portions that respectively correspond to the first plug holes and second plug holes. The flexible element pushes the cover body so that the cover body is covered between the first plug holes and the second plug holes. Thereby, the apparatus can prevent foreign matter from being plugged into a socket, and prevent electric shock to user.
