The socket is common electrical connection equipment in daily life, and the electrical pins of the plug can be inserted into the socket to easily provide required electric power for the used electrical equipment. However, such convenience also brings safety concerns for the use of the electrical appliance. When the electrical pin of the plug just contacts the conductive compression spring copper sheet in the socket, the electric power connection between the plug of the electric appliance and the socket is immediately established, so that the electrical pin which is not yet inserted into the socket body is provided with electric power; in contrast, when the plug is removed and not completely removed from the socket, the electrical pins of the plug are in a charged state, which exposes the user, especially the elderly or children, to a high degree of risk of electric shock. There are many designs that attempt to address this risk of electrical shock, most of which are purely mechanical means to delay the metal contact of the plug pins with the conductive compression springs of the receptacle or to prematurely break the metal contact when the plug is pulled up.
