Abstract
An electrical socket has a safety device comprising a shutter member with at least a pair of lugs engageable by respective pins of an electrical connector plug inserted into the socket. The shutter member has a rest position in which the lugs mask apertures into the body of the socket, thereby to prevent the pins from contacting electrical terminal contacts in the socket. The rest position is defined by the lugs bearing against abutments, and at least one of the lugs is also engaged by its abutment means, to arrest the shutter member in its rest position. The lugs are deflected by the thrust force thereagainst of the pins of the inserted plug, so as to be disengaged from the abutment means. The lugs have inclined surfaces so that said thrust force of the pins will cause displacement of the shutter member to unmask the apertures for insertion of the plug. The shutter member can be a rotary or a linearly displaceable member, and is spring-loaded towards its rest position.
