Abstract
A safety socket includes a main body, a restraint mechanism and a release mechanism. The restraint mechanism includes an immovable end and a movable end. The immovable end is disposed in the main body. The movable end has a through hole. The through hole corresponds in position to one of insertion holes of the main body. The movable end has an annular protruding portion axially extending from the wall of the through hole. The annular protruding portion has a free end which is curved outward. The safety socket can prevent a plug from being disengaged from the socket by accident. The outer surface of the conductive pin of the plug won't be scraped and damaged by the wall of the through hole to enhance the service life and safety of the plug.
Claims5
A safety socket for a plug, the plug comprising a plurality of conductive pins, the safety socket comprising:
- a main body having an end surface, the end surface of the main body being formed with a plurality of insertion holes for insertion of the plurality of conductive pins of the plug;
- a restraint mechanism comprising an immovable end and a movable end, the immovable end being disposed in the main body, the movable end being disposed at one end of the immovable end, the movable end having a through hole, the through hole corresponding in position to one of the insertion holes, the movable end having an annular protruding portion axially extending from a wall of the through hole, the annular protruding portion having a free end which is curved outward;
- and
- a release mechanism movably connected to the main body and bringing the movable end of the restraint mechanism to switch to an engaging position or a release position, the movable end of the restraint mechanism tending to move to the engaging position, wherein when the movable end of the restraint mechanism is located at the engaging position, one of the conductive pins of the plug is restrained by the movable end of the restraint mechanism so that the plug is unable to disengage from the main body by accident;
- wherein when the movable end of the restraint mechanism is located at the release position, the conductive pins of the plug are able to be inserted in or pulled out of the insertion holes.
