Abstract

The utility model discloses a safety socket operated by keys, which overcomes the defect that the existing socket is easy to arise the electric shock accident when the bolt of the socket power is contacted with the sheet metal of the socket and the circuit turns on instantly. The utility model is characterized in that the socket is provided with a mechanical lock; a static contact piece is fixed on the sheet metal of the socket; an insulating board is arranged on the locking pin of the mechanical lock, and a movable contact piece is arranged on the insulating board. The utility model has the advantage of simple structure. The bolt needs not to withdrawal after watching or listening to the common electric appliance, and so as to take off the key on the socket; once the key is taken off, even the bolt is inserted in the socket, but can not conduct the electricity. Hence, the electric shock accidents can be avoided, and the event of the always lighting without person can also be avoided.

Description

Safety socket

The utility model belongs to a kind of essential electronic element, the key operated safety socket of particularly a kind of usefulness.

Existing supply socket, generally all be on base, to be screwed conductive metal sheet, during use, when the latch of external power supply when sheet metal in the socket contacts, circuit is conducting at once, if the copper sheet of false touch latch or when moist on hand is easy to take place electric shock accidents, when particularly children's mistake stretches into conductive body in the jack, easier generation electric shock accidents; In addition, after using, electrical equipment (as television set) needs latch is taken out from socket, otherwise, will continue power supply, will influence its useful life to some electrical equipment.

The purpose of this utility model is to solve the problems referred to above that supply socket exists in the prior art, provides a kind of and can avoid the copper sheet of false touch latch and the safety socket that children's mistake stretches into conductive body the electric shock accidents that causes in the jack; In addition, can prevent that because the head of a family stays out, child at will uses various electrical equipment and the various adverse consequencess brought.

The utility model is to have set up a mechanical lock on common socket, fixes a static contact on the sheet metal in common socket; An insulation board that is synchronized with the movement with lock pin is installed on the lock pin of mechanical lock, and the upper end of insulation board is equipped with movable contact spring and connects with power-line terminal by lead simultaneously.During use, control by key, make insulation board upper and lower mobile, static contact in movable contact spring on the insulation board and the socket on the sheet metal combines or separates, control the closure and the disconnection of power supply thus, and have only when power supply and under the situation of outage, could transfer to key, therefore can prevent to close power supply by mistake.

Advantage of the present utility model is simple in structure because with being switched on or switched off of key control power supply, so, at general electrical equipment, as unnecessary dial-out latch after the audiovisual such as television set, broadcast receiver, as long as and take off key on the socket; And once key is taken off, can not conduct electricity even the electrical equipment latch is inserted on the socket yet, therefore, can avoid the electric shock accidents that takes place because of the copper sheet of careless false touch latch and when moist on hand, can prevent that also children's mistake from stretching into the electric shock accidents that may cause in the jack with conductive body; Owing to one section insulation board, and do not worry using metal key that electric shock accidents can take place between key and the power contacting plate; Simultaneously, when having a power failure suddenly key is taken off, when sending a telegram here again, power supply can not cause the phenomenon of unmanned altar lamp because disconnected.
