Technical background

Connector is widely used as wireless being electrically connected in the small household appliance, for these years, various connectors go out infinite to the greatest extent, as ZL94194173.6, connector in the ZL02118912.9 patent documentation is the present the most wireless electrical cnnector of extensive use, two schemes that embodiment is showed, all exist in the insertion process, when the contact on the newel and the contact on the brace exist near apart from the time, because connecting, slow-action can produce strong electric arc, make the contact produce high temperature, tens times work, will make brace conduct heat institute extremely because of the contact on it, and cause metal influenced by very high temperature and variable color is softening, influence the initial pressure and the ampacity of brace, so problem is more serious.Though its another embodiment changes into the side energising, also can't change it because longer relatively in the insertion process because of the moving time in contrast wink, seriously draw arc phenomenon and exist.Connector in the ZL00233024.5 patent documentation, though it has changed the infix form of ZL94194173.6, the contact and the working point that are inserted into process space out, to avoid cut-in point to produce the burnt mark that stays behind the electric arc, the normal energising of influence, and make it to be displaced to not the working face contact of being burnt by electric arc, improve contact point and working point and be in same position, and caused the defective of loose contact.But because of it can't avoid the generation of electric arc, connecting ring is again a contactless silver-plated plane simultaneously, thousands of time draw electric arc and patch up and down after, the traces of burning that stay on connecting ring have been that scar is full of stains or spots, therefore, head it off is still very urgent, ZL200410016181.3 is arranged again, and it is that a kind of use earthing rod withstands plastic cement phase line and zero line then, the wiring copper sheet then to the contact chip of the becket that interrelates respectively on the contact compress, and making current, it is before non-compressing, the becket non-transformer, can prevent that so hand-held metal buttress shaft from inserting the back electric shock accidents takes place, but still do not solve near the time, because of various factors cause slow-action or near apart from the time produce the phenomenon of strong electric arc.

Summary of the invention

Serious problems according to above all kinds of connectors exist the present invention proposes a complete technical solution different from the past, thereby have fundamentally solved existing this problem of connector in the past.

It is a kind of electrical cnnector that contains the kick device, it comprises a connector and Connection Block, a main body plastic that accessory is installed is arranged in the described connector, two metallic conduction rings, a metallic conduction post is formed, each conductive component all has a binding post to be connected, a main body plastic that accessory is installed is also arranged in the described Connection Block, and conducting ring, the contact chip that conductive pole combines, two contact chips directly are connected with binding post, it is characterized in that one of them contact chip in the Connection Block contains C shape structure in the middle of one flexure strip, it produces quick-action and the conducting ring of binding post and connector is connected into path mutually when conducting ring pushes.Thereby fundamentally solved existing connector and be the structure that phase line connects slow-action, avoided the generation of safety problem, prolonged useful life greatly.

In the layout of connector, in order to guarantee safe handling, earth connection is arranged on middle ring, phase line is arranged on outer shroud, zero line is arranged on inner prop, kept the safe distance of phase line and zero line to greatest extent.

When the connector in the connector inserts Connection Block, adopt first earth connection contact, back zero line contact, kick mechanism is used in the back again, and phase line was connected in moment, cause the full loop energising and operate as normal, when connector is extracted Connection Block, adopt the outage that resets earlier of kick structure, zero line is cut off the power supply, again earth connection is disconnected at last, to guarantee that earth connection is in contact condition in overall process.

When the actuating energy of kick device is set, preferable scheme is to activate on the contact terminal of the contact chip that is arranged on the kick device, when the connector copper ring inserts, its contact terminal is not charged, but connects with copper ring, only when further inserting, the kick device activates, another contact terminal on it and the contact terminal on the phase terminal, at this moment the contact chip on the kick device is just charged, and it can prevent that unexpected putting into as the metal object of safety pin and so on causes electric shock accidents in the Connection Block groove.

Specific implementation method

According to Fig. 1, Fig. 2, shown in Figure 3, the Connection Block of present embodiment is installed plastic (1) by main body, ground connection contact copper sheet (2), ground connection ground wire terminal (3), zero line contact chip (4), zero line contact terminal (5), phase linear elasticity kick copper sheet (6), phase line splicing ear (7), kick structure fixed mount (8), the kick copper sheet activates contact (9), contact under the kick copper sheet (10), the strong point (11) of kick fixed mount and C type copper sheet, phase line splicing ear contact (12), moving point (13) is formed before and after kick fixed mount and the elastic copper sheet, and the connector of present embodiment is installed plastic (15) by main body, zero line newel (16), ground loop (17), phase wire loop (18), zero line binding post (19), earth connection binding post (20), phase terminal (21) is formed.

Its course of work is as follows:

1, as shown in Figure 2, it does not insert the state of Connection Block at connector, phase linear elasticity kick copper sheet (6) on the Connection Block, because of activating contact (9), its kick copper sheet not pushed by external force, the center of circle direction that plastic (1) is installed to main body in whole phase linear elasticity kick copper sheet (6) lower end is at a stalemate, contact (10) is the disengagement shape with phase line splicing ear contact (12) under its kick copper sheet, even on the phase line contact chip, switch on, it is charged also can not make the kick copper sheet activate contact (9), and this is a quite safe structure.The Danger Electric shock risk that brings when this structure can be avoided artificially inserting connector with thin metal object fully.

2, as shown in Figure 4, when connector inserts Connection Block, the ground loop of connector (17) is at first run into the ground connection contact copper sheet (2) of Connection Block, cause ground connection ground wire terminal (3) to link to each other with ground loop (17) the earth connection binding post (20) of connector by ground connection contact copper sheet (2), structure connects earth-return, and this moment, other electrode was not on-state.

3, as shown in Figure 5, when connector further inserts Connection Block, zero line newel (16) on the connector communicates with zero line contact chip (4) on the Connection Block, cause zero line contact terminal (5) to link to each other with zero line newel (16) the zero line binding post (19) of connector by zero line contact chip (4), structure leads to the zero line loop, this moment, the phase line electrode was still not charged, was in not on-state.

4, as shown in Figure 6, when connector further inserts Connection Block, activate contact (9) when colliding at connector phase wire loop (18) and kick copper sheet, because the displacement of contact is fine motion and not destroyed (13), (11), the equilibrium relation between (9) three, make the bottom of phase linear elasticity kick copper sheet (6), still different in situ.The kick copper sheet activates contact (9) though connect with wire loop (18) mutually, and does not collide with phase line splicing ear contact (12) in its underpart, and no power still.

5, as shown in Figure 7, when connector further inserts Connection Block, because phase wire loop (18) activates the compressing of contact (9) to the kick copper sheet, and force its outside displacement, and destroy 3 equilibrium relations of (13), (9), (11), it is because the effect of the shell fragment of C type structure, cause contact (10) under the kick copper sheet of lower end of phase linear elasticity kick copper sheet (6) moment outwards displacement contact with phase line splicing ear contact on the phase line splicing ear (7), and cause phase line also to be connected, finished the complete conducting of three electrodes of connector;

6, return by the order of Fig. 7, Fig. 6, Fig. 5, Fig. 4 successively as its each electrode when connector is extracted, and finally finish the disconnection fully of three electrodes of connector.
