Aforesaid connector is covered with a lip in wherein said.

Aforesaid connector, wherein said connector are designed to respectively be up and down the structure of multilayer guide card.

Preceding described connector is provided with the male and female buckle between the inwall of wherein said enclosing cover and the outer wall of inner cap.

Aforesaid connector wherein is provided with elastic construction between inner cap and enclosing cover.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model connector:

One, the connection effect of connector makes that because of the compressing of inner cap contact is more tight, and can not produce loose contact because of using with the passing of time; And

Two, the design of lip makes dust in air be difficult for accumulating what connector inside, relative raising the life cycle of connector (life time).

Three, reduce the wearing and tearing of plug, the noble metal of electroplating surface becomes more durable, and under identical durable degree, electroplating thickness can reduce, and cost is reduced.

In sum, the utility model connector, it is had large improvement technically, and has produced handy and practical effect, and has the effect of enhancement really, thereby is suitable for practicality more, really is a new and innovative, progressive, practical new design.

Below in conjunction with accompanying drawing and preferred embodiment, to according to the connector that the utility model proposes, its concrete structure, feature and effect thereof, describe in detail as after.

See also shown in Figure 2, connector of the present utility model be in order on the connecting circuit plate 22 as the golden finger 221 of the first terminal, it mainly comprises an enclosing cover 23, an inner cap 24 and guide card 25.Guide card 25 is inner and be connected with system framework 21 in enclosing cover 23 as one second terminal ， Let, in order to be connected with golden finger 221 on the circuit board 22.And inner cap 24 is slidably in enclosing cover 23, and prop up inner cap 24 bottoms 241 when forcing this inner cap 24 to slide into the location of enclosing cover 23 bottoms 231 in circuit board 22, protruding grain 243 on this inner cap 24 can be oppressed guide card 25, the salient point 251 of guide card 25 is closely contacted with golden finger 22 on the circuit board 22, and lip 244 up and down can contain circuit board simultaneously.Thus, not only can exempt from what and use with the passing of time loose contact, more can prevent the intrusion of dust, be one to have industrial value De Let Meter really.

Fig. 3 is the schematic diagram after circuit board 22 inserts connector.Wherein but the protruding grain 243 of inner cap 24 withstands guide card 25, and the salient point 251 of guide card 25 tail ends is contacted with

golden finger

221, and 221 of golden fingers can transmit power supply to this guide card 25.Certainly, guide card 25 can be copper product and makes, and the both sides of this inner cap 24 then have elasticity, makes connector expansible mouth, accepts circuit board 22.In addition, guide card 25 also can have elasticity, makes circuit board extract out when this connector, and expansible comes.

After the golden finger 221 of circuit board 22 is placed in connector, closely fix in order to make inner cap, people can be between the outer wall of the inwall of enclosing cover 23 and inner cap 24 design male and female buckle.In addition, when circuit board 22 is extracted out, if desire to take out of inner cap 24 ， The can design spring and so between inner cap 24 and enclosing cover 23 device.Certainly, all this design detailss are and are familiar with present technique person and can implement according to this.On the material of inner cap, consider the heat radiation between guide card 25 and the golden finger 221, then can adopt comparatively heat proof material.

Fig. 4 and Fig. 5 are another embodiment, and it is to be applied on the multi-layered type circuit board 40.Multi-layered type circuit board 40 each mask have two layers of mutual nonconducting

golden finger

41,42, when the power supply on two

golden fingers

41,42 is positive and negative each other, and the laser propagation effect that then has the inductance near-zero.This embodiment is not had by existing market, and its advantage can reduce inductance significantly.In addition with big current delivery, this connector can more have the advantage that suppresses the inductance generation than traditional approach, existing traditional connector is when big electric current, be to adopt to add the thick line footpath, and this connector is a Zeng Jia Long degree reaching the needs of electric current, moreover flat partially frame mode is low far beyond the structure inductance of round wire.

In response to the design requirement of multi-layered type circuit board 40, connector of the present utility model then can be designed to respectively be up and down the structure of multilayer (Fig. 4 is two layers) guide card 44,43.43,44 of bi-conductive plates can be got involved the effect that an insulating barrier 49 Come reach insulation.A protuberance 45 then can be designed in the bottom of inner cap 47, when withstanding location on this protuberance 25 so as to the golden finger in circuit board, makes the bottom 48 of these inner cap 47 retractions to this enclosing cover 46.Fig. 5 inserts the schematic diagram of connector for circuit board, wherein the salient point 431,441 of

guide card

43,44 since the compressing of the protruding grain 471 of inner cap and respectively with circuit board 40 on

golden finger

41,42 closely contact, lip 472 is then sealed the opening of connector, and dust can not entered wherein.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
