When the clamping force of the socket is too large, great difficulty is brought to the plug to be plugged, and the socket is inconvenient to use; when the clamping force of the socket is too small, the plug is easy to loosen, and poor contact can be caused. In addition, when the socket is used, particularly when the plug is pulled out of the socket, the plug is easy to touch the conductive rod of the plug carelessly, and a large electric shock risk exists.
To solve the above problem, we propose an easy-to-plug safety socket.
