<p>The invention consists of an electric socket with internal block capable of movement controlled by the electric plug inserted into it, following which there is movement from an "off" position - in which the plug electrodes are insulated from the phase electrodes of the socket and the plug is mechanically free for removal - to an "on" position in which the plug electrodes are electrically connected to the socket electrodes and the mechanical parts of the plug are mechanically coupled with the corresponding parts of the socket to impede their release, except by means of the movement which returns the internal block of the socket to the "off" position. <IMAGE></p> |
