Problems solved by technology

[0002] At present, the power supply device is generally composed of a socket and a plug. The socket is generally installed on the wall or the ground. When the socket is plugged into the socket, it is powered on, so as to supply power to the electrical equipment. Although the traditional socket and plug are more convenient to use, in the traditional socket structure, the conductive shrapnel is generally exposed in the socket, and the socket Generally, it is also connected with the outside world. Therefore, it is equivalent to exposing the conductive shrapnel. If a child inserts the metal rod into the jack, it will cause an electric shock accident, accidentally knocking over the water cup or spilling water on it for other reasons. There will be a short circuit in the socket, so it will have a great impact on the equipment, and some sockets that can close the socket have also appeared recently, but this socket can also make the metal rod energized when the ordinary metal rod is inserted , there are still security risks
