Abstract
The invention discloses a socket protective door which is arranged in a shell body composed of a cover plate and a base. A door plate which can open or close insertion holes during sliding is arranged in the shell body. The upper side of the door plate is provided with a first push block, a second push block and a sliding block arranged between the first push block and the second push block, and the first push block and the second push block can slide. When a single-stage plug is inserted into one of the insertion holes, the first push block or the second push block is pushed, and the door plate blocks the insertion holes to prevent a conductive material from being inserted. When children mistakenly insert the conductive material into two insertion holes of the cover plate, at least one of the push blocks can not be pushed under the action of leftward and rightward sliding of the sliding block on the conditions that the two push blocks are not pushed at the same time or the push blocks are pushed at the same time but push forces are different on the two sides, and therefore the electric shock phenomenon can be avoided. The socket protective door solves the problem that an existing socket protective door is poor in reliability.
