Abstract

The utility model discloses a signal line waterproof plugging connector structure for an electric car. The plugging connector structure comprises a plugging connector male terminal and a plugging connector female terminal. The male terminal comprises a male terminal rubber-coating member and a male terminal positioning member. The female terminal comprises a female terminal rubber-coating member and a female terminal positioning member. A first male terminal step is arranged on the male terminal positioning member, and a first female terminal step corresponding to the first male terminal step is arranged on the female terminal positioning member. The length of the female terminal rubber-coating member is larger than the length of the female terminal positioning member. A second male terminal step is arranged on the male terminal rubber-coating member, and a second female terminal step corresponding to the second male terminal step is arranged on the inner side of the female terminal rubber-coating member. Fool-proof projections are arranged on the inner side of the male terminal positioning member, and fool-proof slots corresponding to the fool-proof projections are arranged on the female terminal positioning member. Water is effectively prevented from going into the signal line waterproof plugging connector structure for the electric car when the structure is used, and the structure can be more rapidly and safely connected.

Description

The holding wire waterproof dongle configuration of electric motor car

Technical field

The utility model relates to electric motor car, relates in particular to the holding wire waterproof dongle configuration of electric motor car.

Background technology

Current its male and female end of electric motor car holding wire dongle configuration only has a step to cooperatively interact, cause the contact area between the male and female end little, coordinate not closely, easily because car body jolts, make to get loose between plug-in unit in process is ridden in electric motor car, cause electric motor car to work, coefficient of safety is low; And between plug-in unit, there is no the fool proof point, during grafting, not only there will be the situation of plug-in unit anti-plug, and the pin of male end easily ruptures when pegging graft.

Summary of the invention

The utility model for the plug-in unit existed in prior art easily come off, the defect such as pin easy fracture, a kind of holding wire waterproof dongle configuration of new electric motor car is provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The holding wire waterproof dongle configuration of electric motor car, comprise the plug-in unit male end, the plug-in unit female end, described plug-in unit male end comprises male end encapsulate spare, the male end keeper, described plug-in unit female end comprises female end encapsulate spare, the female end keeper, on described male end keeper, be provided with the male end first step, on described female end keeper, be provided with the female end first step corresponding with the male end first step, the length of described female end encapsulate spare is greater than the length of female end keeper, on described male end encapsulate spare, be provided with the male end second step, described female end encapsulate spare inboard is provided with the female end second step corresponding with the male end second step, described male end keeper inboard is provided with the fool proof projection, on described female end keeper, be provided with the fool proof groove corresponding with the fool proof projection.

After plug-in unit male end and plug-in unit female end are pegged graft mutually, the male end first step will fit with the female end first step, and the male end second step will fit with the female end second step, and the contact range between the male and female end is larger, coordinate tightr and difficult drop-off, can prevent better that moisture from entering plug-in unit inside; The length of female end encapsulate spare is greater than the length of female end keeper, and while making plug-in unit male end and plug-in unit female end peg graft, the male end keeper can slide and contact with the female end keeper along female end encapsulate spare inwall, more convenient during installation; Fool proof projection and fool proof groove can effectively prevent the plug-in unit anti-plug, avoid causing because of operate miss the damage of pin, more safe and practical.

As preferably, the holding wire waterproof dongle configuration of electric motor car described above, described male end encapsulate spare and female end encapsulate spare adopt soft plastic to make, and described male end keeper and female end keeper adopt hard plastic to make.In use procedure, information wire often can be fitted in electric motor car to save space by bending, and the male end keeper that hard plastic is made and female end keeper make the place of patching expose gap can avoid bending the time, cause moisture from gap, entering plug-in unit inside; Soft plastic makes male end encapsulate spare and female end encapsulate spare can increase the pulling-out force between plug-in unit male end and plug-in unit female end, prevents from causing plug-in unit male end and plug-in unit female end accidental separation because of operate miss.

Fig. 1 is the structural representation of plug-in unit male end in the utility model;

Fig. 2 is the structural representation of plug-in unit female end in the utility model;

Fig. 3 is the cross-sectional view of plug-in unit female end in the utility model;

Fig. 4 is the structural representation when in the utility model, plug-in unit male end and plug-in unit female end are pegged graft.

Embodiment

Below in conjunction with accompanying drawing 1-4 and embodiment, the utility model is described in further detail, but they are not to restriction of the present utility model:

Embodiment 1

As shown in Figures 1 to 4, the holding wire waterproof dongle configuration of electric motor car, comprise plug-in unit male end 1, plug-in unit female end 5, described plug-in unit male end 1 comprises male end encapsulate spare 2, male end keeper 3, described plug-in unit female end 5 comprises female end encapsulate spare 6, female end keeper 7, on described male end keeper 3, be provided with male end first step 31, on described female end keeper 7, be provided with the female end first step 71 corresponding with male end first step 31, the length of described female end encapsulate spare 6 is greater than the length of female end keeper 7, on described male end encapsulate spare 2, be provided with male end second step 32, described female end encapsulate spare 6 inboards are provided with the female end second step 72 corresponding with male end second step 32, described male end keeper 3 inboards are provided with fool proof projection 4, on described female end keeper 7, be provided with the fool proof groove 8 corresponding with fool proof projection 4.

As preferably, described male end encapsulate spare 2 and female end encapsulate spare 6 adopt soft plastics to make, and described male end keeper 3 and female end keeper 7 adopt hard plastics to make.

In a word, the foregoing is only preferred embodiment of the present utility model, the equalization that all scopes of applying for a patent according to the utility model are done changes and modifies, and all should belong to covering scope of the present utility model.
