Abstract

The utility model utility model provides a safe power socket, comprising a socket body, wiring terminals in the socket body, and a guard plate closely disposed on a jack in the socket. The guard plate is a movable baffle plate, covering on a pair of jacks to completely block the jacks. The jacks can be double holes or three holes. Thus, the guard plate separates the jacks and the wiring terminals, preventing an external plug to insert. An end of the guard plate is connected with a safe lock. After a corresponding key is inserted into the safe lock, the safe lock is opened, and the locked guard plate recovers to move and leave a position of the jacks. The plug can enter inside of the socket smoothly and be plugged on the wiring terminals. A lock can be added on the socket, and only by using the special key, electricity can be obtained from the socket, so safety of the socket is greatly improved.

Description

A kind of safety power source plug socket

Technical field

The utility model relates to the Electrical Safety field, relates in particular to a kind of safety power source plug socket

Background technology

Nowadays supply socket is widely used, but there is huge safety problem in general supply socket, does not have safety prevention measure as the socket of public arena, and anyone can insert outside electricity consumption setting, has illegal electricity and the potential safety hazard stolen.Have in addition in child's the family, many children often work as toy with socket, easily metal device are inserted in the receptacle sockets, cause electric shock easily.Therefore the socket Electrical Safety is a problem that needs solution.

Summary of the invention

The utility model is in order to solve the safety utilization of electric power problem, a kind of safety power source plug socket is provided, it comprises jack body and inner binding post thereof, the jack place is close in socket inside a guard plate, guard plate is that an active clapboard covers a pair of jack inside jack is blocked fully, and jack can be that diplopore also can three holes.Guard plate separates jack and binding post and can stop external plug to be inserted like this, guard plate one end is connected to safety lock, just safety lock can be opened after in safety lock, inserting corresponding key, the guard plate that is lockable is unlocked, just can reactivate and leave jack position, plug just can enter socket inside smoothly and be inserted on the binding post.

Above-mentioned guard plate is connected to rotary type with safety lock and is connected, after key inserts, just can drive the guard plate rotation by the rotation key its part that covers jack is moved on to the jack next door, guard plate is removed from blocking jack fully, allows the pin of plug to enter socket inside.

Above-mentioned guard plate is connected with safety lock also can be telescopic connection, after inserting, key just the covering jack position part stretch mode of guard plate can be retracted in the safety lock by rotating key, as adopt family to prevent locking structure, allow the pin of plug to enter socket inside.

The further improvement of above-mentioned technical scheme is, module automatically resets in the safety lock, this reseting module mainly is made of a spring, guard plate leaves initial position when safety lock is opened, the compressed generation of spring recovers tension force, when plug was extracted from socket, guard plate was return original position automatically and is covered jack under the spring action.

The utility model has been obtained following technique effect:

Just can have only the key by special use just can use the socket power taking for socket adds a lock by the utility model, strengthen the fail safe of socket greatly.

Description of drawings

Fig. 1 is lockable schematic diagram for safety power source plug socket of the present utility model;

Fig. 2 opens for safety power source plug socket of the present utility model and the schematic diagram when having plug to insert.

Embodiment

Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

Fig. 1 is that safety power source plug socket of the present utility model is lockable schematic diagram, comprise jack body 1 and inner binding post 4 thereof, be that socket inside is close to jack 2 places a guard plate 5 is arranged, guard plate 5 is connected to safety lock 3, inserting corresponding key 6 backs in safety lock 3 just can open safety lock 3, the guard plate 5 that is lockable just can activity leave jack 2 positions, and plug 7 just can be inserted on the binding post 4 smoothly.

Embodiment 1:

Here adopt on the common double spring hole scoket basis and implement the utility model, see Fig. 1, it fixedly is to be connected to external power source on the wiring board that there are two binding posts 4 socket inside, each binding post 4 is the parallel double copper sheet, two copper sheets top curves inwardly, two copper sheets clamp pin 8 when having the external plug of stretching 7 to insert, and realize the connection of electric current.Guard plate 5 is connected to telescopic the connection with safety lock 3, the anti-theft lock of similar antitheft door, after inserting, key 6 just can realize the flexible of guard plate 5 by rotating key 6, after inserting, key 6 just the covering jack 2 position part stretch modes of guard plate 5 can be retracted in the safety lock 3 by rotating key 6, allow the pin 8 of plug 7 to enter socket inside, see Fig. 2.

Module automatically resets in the above-mentioned safety lock 3, a spring assembly constitutes in the reseting module, in jack 2 during no plug, rely on spring tension that guard plate 5 is released and cover twin jack 2, external plug can't be inserted, when inserting safety lock 3 keys 6 and rotating, driving guard plate 5 shrinks in the safety lock, the guard plate 5 of covering twin jack 2 is just removed and can insert external plug 7 in twin jack 2, this moment, spring was compressed, produce recovery tension force promotion guard plate 5 and withstand pin 8, can extract the state that key 6 does not influence safety lock 3 this moment.

Finishing using when socket pulls the plug out of the socket 7 the time, and guard plate 5 is subjected to the promotion of spring tension to return to original position again and blocks twin jack 2, needs just can open with key again.

Embodiment 2

The utility model also increases an alarm module on above-described embodiment 1 basis, the pressure sensitivity alarm module is arranged in the safety lock 3, when safety lock 3 is locked, if guard plate 5 is subjected to the external object pressure from jack 2, just triggers acousto-optic and vibrations are reported to the police.The pressure sensitivity here detects and realizes by a compression spring switch, compression spring is connected with guard plate 3 parts that are positioned at safety lock 3, under normal circumstances, compression spring acts on the part of on the guard plate 5 it being stretched out safety lock 3 and is pushed on the jack 2, when having material to enter in the jack 2 to touch on the guard plate 5, it is pushed away jack 2, a mechanical switch in the safety lock 3 will be pressed, this mechanical switch is exactly the switch of alarm module, just triggers mechanical shock, sound and luminous warning.Caution is worked as front socket and is in the lock state, and could use socket after must opening the lock with the key.Can play certain fright effect to the infant like this, avoid it to remove to play with socket and bring Danger Electric shock risk.
