Abstract

The present invention relates to a safety socket consisting of the components of socket panel, crown door, crown bar, crown bar spring, coducting strip spring, contactor, connecting terminal, plug-in component and casing. Said invention can be used as powder socket, and possesses the function of preventing electric shock.

Description

Safety socket

The present invention is a kind of supply socket.

In the environment of our daily life, work, the employed socket overwhelming majority does not have electroshock-proof function.Especially the socket that low level is installed in the dwelling house usually makes the safety concerns of the heads of a family for the child.

Existing partial socket, the form that employing adds " shutter " solves this problem, the socket that adds shutter mainly contains two kinds: a kind of is the socket of built-in shutter, promptly between receptacle sockets and connector, settle a shutter by the spring closedtop, connector charged in the socket is covered, when the plug insertion, the inclined-plane on shutter produces component and makes shutter by jack-up, and plug could contact power supply; Another kind is external shutter " an enclosed type safety socket "; its patent No. is 932001564; its feature is: settle a shutter that is headed on by spring in the receptacle sockets outside; have on the shutter and the same shape of the jack of socket own; unidimensional patchhole; when socket did not use, the jack position of jack on its shutter and socket itself produces " dislocation " made the insertion object can not touch charged connector in the socket.

These sockets have following defective in actual use: built-in protection gate-type socket, with objects such as iron nail, key be easy to insert and contact the electricity connector; Though external protection gate-type socket is safe and reliable, to follow the operation sequence of " inserting---mobile plug and shutter---inserts again " when using, its inconvenient operation.

Task of the present invention is that a kind of improved supply socket will be provided, and it had both had electroshock-proof function, and was safe and reliable, is applicable to that standard plug is easy to operate again.

Design principle of the present invention is: will connect the terminals word and the connector branch disconnection that is used to patch plug of external power supply in the socket, its connector was not charged when socket was not used.Work as plug insertion socket, the linkage of being made up of parts such as roof door, push rod, spring, conducting strips in the socket by moving up and down or rotating, could make socket enter the energising operating state circuit communication between binding post and the connector; Transfer to plug, the disjunction immediately of the circuit between binding post and the connector, connector no longer includes.If use an object, insert as the arbitrary jack from socket such as iron nail, key, and make to disclose to contact to connect and draw together part and also can not cause getting an electric shock.

Task of the present invention is finished as follows: socket is made up of drain pan, middle box and three parts of panel.Binding post, connector are placed in the drain pan, it between drain pan and panel middle box, in the middle box linkage parts such as roof door, push rod, conducting strip and spring are installed, drain pan, middle box, panel, roof door, push rod are made of insulating material such as plastics, and conducting strip is made with copper or other material with good conductive ability.Because exist the two-stage plug to use and the branch of three grades of plugs with socket, therefore, this socket also should have dual mode mutually, i.e. two jacks control and single jack control.Their concrete structure is: in two jack control modes, in middle box, be divided into roof door chamber and push rod chamber from bottom to top along the center line between two jacks, indoor installation roof door of roof door and balancing spring, roof door is indoor a joist, joist is on the center line between two jacks, roof door places on the joist, rely on balancing spring to keep the balance at two ends, the roof door two ends have the inclined-plane to be used for producing thrust upwards, the patchhole of inclined-plane, roof door two ends on the socket panel, make patchhole be sealing or semiclosed shape, roof door also can turn an angle around joist (less than 90 °) at the indoor certain distance that both can move up and down of roof door (general 2mm is to the patchhole height), be to be placed in the indoor push rod of push rod directly over the roof door, one end of push rod places the roof door center, and the other end is installed push rod spring, and push rod can move up and down in that push rod is indoor; In single jack control mode, roof door, roof door chamber and balancing spring are not set, directly,, make patchhole be sealing or semiclosed shape with the ground wire utmost point patchhole of inclined-plane over against socket with an end bevel shape of push rod.Conducting strip and conducting strip spring are installed in the both sides of push rod, and conducting strip is subjected to the control and the effect of push rod and conducting strip spring, move up and down accordingly or rotate with moving up and down of push rod, thereby be communicated with or disjunction binding post and connector between circuit.The working method of socket is:

1) inserts plug, produce upwards (or downwards) thrust through the inclined-plane of roof door or push rod end, make upwards (or the downwards) motion of roof door, push rod, push rod spring is compressed simultaneously, the conducting strip of push rod control moves up or down accordingly or rotates under the control and effect of push rod, conducting strip spring, and two ends contact connector and external power supply contact respectively, with the circuit communication between binding post and the connector, socket enters the energising operating state;

2) transfer to plug, under the elastic force effect of push rod spring and conducting strip spring, push rod descending (or up), the circuit between conducting strip disjunction binding post and the connector, connector no longer includes;

3) insert with arbitrary jack of objects such as iron nail, key from socket, because connector does not have electricity, institute and make to disclose and contact connector can not get an electric shock yet.

The invention will be further described below in conjunction with accompanying drawing.

With reference to Fig. 1, when socket did not use, conducting strip (8) was not communicated with the circuit between binding post (15) and the connector (10), and connector (10) does not have.

With reference to Fig. 8, in an object inserts socket, roof door (3) is because of the two ends unbalance stress, can only turn an angle around joist (7), and can not integral body upwards promote push rod (1), so push rod (1) can not move upward, conducting strip (8) is failure to actuate, circuit between binding post (15) and the connector (10) is still the disjunction shape, so, and make to disclose and contact connector (10) and also can not get an electric shock.

With reference to Fig. 2, the insertion pin (14) of plug inserts in the socket

A, roof door (3) two ends are subjected to the upwards thrust that the inclined-plane produces simultaneously, and roof door (3) and push rod (1) integral body move upward.The inclined-plane of B, push rod (2) produces upwards component, makes push rod (2) rectilinear motion downwards.The motion of push rod (1) and push rod (2), drive conducting strip (8) and produced motion accordingly, with the circuit communication between binding post (15) and the connector (10), socket carries out energising work to conducting strip (8) at " bridge formation " between external power contact (9) and the connector (10).
