Abstract

The utility model provides a cigarette lighting connector for automobiles, which comprises a casing, a connector module, a connecting piece, a cathode snap spring and an anode copper cap. The anode copper cap is arranged on an end face of the upper end of the casing, wherein two annular clamping grooves are arranged outside the upper end of the casing. Due to a fact that the clamping grooves are arranged on the upper end of the casing and can be arranged in corresponding inserting grooves of the automobile stably, the cigarette lighting connector can keep stable even in a big shock during practical application. The cigarette lighting connector has the advantages of being stable in positions and difficult to fall in the big shock.

Description

The automobile-used joint that lights a cigarette

Technical field

The utility model relates to a kind of automobile-used appurtenances, relates in particular to a kind of automobile-used joint that lights a cigarette.

Background technology

Automobile has entered production, various fields in life, and especially the popularity of passenger car is compared with all be significantly improved any period in the past.Automobile has incorporated people's life, and in order to improve the automobile comfort level, various vehicle-mounted equipments are also progressively perfect, and for example automobile all is equipped with the automobile-used joint that lights a cigarette mostly.But the existing automobile-used joint that lights a cigarette is because the defective of structural design, when vehicle runs into rugged road surface and jolts, when perhaps running into snub, comes off easily.

Summary of the invention

The purpose of this utility model is to provide a kind of automobile-used joint that lights a cigarette, during with the relatively poor or unexpected brake of solution road conditions, and the problem that the existing automobile-used joint that lights a cigarette comes off easily.

To achieve these goals, the automobile-used joint that lights a cigarette that the utility model provides comprises housing, interface module, connector, negative pole jump ring and anodal copper cap, described anodal copper cap is located at the end face of described housing upper end, and wherein, the outside, described housing upper end is provided with two annular slots.

According to a kind of preferred implementation of the above-mentioned automobile-used joint that lights a cigarette, wherein, described anodal copper cap comprises body and cylindrical base, and the diameter of described cylindrical base is greater than the diameter of described body; Described housing upper end comprises a cylindrical cavity, and described cylindrical base is located in the described cylindrical cavity slidably, and the opening of described cylindrical cavity is provided with the projection that prevents described cylindrical base landing.

According to a kind of preferred implementation of the above-mentioned automobile-used joint that lights a cigarette, wherein, the circular arc that described housing is stretched out in described negative pole jump ring both sides is positioned on longitudinal center's point of described negative pole jump ring.

By two annular slots are set in the upper end, and draw-in groove can stably be arranged on the characteristic of automobile associated socket, in actual application, even run into bigger vibrations, it is stable that the utility model also can keep, and as seen the utlity model has position stability, runs into the advantage than the big bang difficult drop-off.

Description of drawings

Fig. 1 is the structural representation of the utility model preferred embodiment;

Fig. 2 is the decomposition texture schematic diagram of the utility model preferred embodiment.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

In order to solve the problem that the automobile-used joint that lights a cigarette comes off easily, the utility model provides a kind of its upper end to have the automobile-used joint that lights a cigarette of draw-in groove.

Fig. 1 and Fig. 2 show the schematic structure of the utility model preferred embodiment, as shown in it, this preferred embodiment first annular slot 7, second annular slot 8 of comprising first housing 1, second housing 4, interface module 3, connector 2, negative pole jump ring 5, anodal copper cap 6 and being positioned at this preferred embodiment upper end outside.The edge engaging of first housing 1 and second housing 4 forms the columniform housing that is similar to of this preferred embodiment, anodal copper cap 6 is located at the end face of first housing 1 and second housing, 4 upper ends, and the outside, the upper end of first housing 1 is provided with the deep-slotted chip breaker 17 of two semicircles, 18, the outside, upper end of second housing 4 is provided with the deep-slotted chip breaker 47 of two semicircles, 48, whereby, the outside, upper end at this preferred embodiment forms two annular slots 7 and 8, after

first housing

1 and 4 engagings of second housing, deep-slotted

chip breaker

17,47 form first annular slot 7, deep-slotted

chip breaker

18,48 form second annular slot 8.Being provided with of annular slot 7,8 can guarantee this preferred embodiment when being given a shock, the associated socket that is arranged at automobile that still can be stable.

In order further to increase the stablizing effect of this preferred embodiment, as shown in Figure 2, the anodal copper cap 6 of this preferred embodiment comprises body and cylindrical base 61, and the diameter of cylindrical base 61 is greater than the diameter of body.Inboard, second housing, 4 upper end is that the relevant position of a deep-slotted chip breaker 42, the first housings 1 also is provided with identical deep-slotted chip breaker, whereby the inner cylindrical cavity that forms in the upper end of this preferred embodiment.Cylindrical base 61 is located in the aforementioned cylindrical cavity slidably, the opening of cylindrical cavity is provided with the projection that prevents cylindrical base 61 landings, for example be provided with projection 43 in the upper surface of the deep-slotted chip breaker 42 of second housing 4, projection 43 can be surrounded with the projection of first housing, 1 correspondence position and be formed an annular protrusion and skids off from deep-slotted chip breaker 42 to prevent cylindrical base 61.So design makes that also the anodal copper cap 6 of this preferred embodiment is capable of expansion and contraction, and existing product is then harder, is easy to flick backward.

In addition, in the groove 41 of two upper ends, 52 embeddings, second housing 4 of the negative pole jump ring 5 of this preferred embodiment and the respective slot of first housing 1, and the circular arc 51 that housing is stretched out in the both sides of negative pole jump ring 5 is positioned on its longitudinal center's point, also be, the circular arc 51 that stretches out this preferred embodiment housing is comparatively upwards close, this design helps to strengthen frictional force, keeps the stability of this preferred embodiment when being given a shock.

In sum, the utility model can keep advantages of higher stability, difficult drop-off by the architecture advances at annular slot and other positions when being subjected to comparatively seriously shaking.

As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
