Description

A kind of cover plate convex closure structure

Technical field

The utility model relates to shielding box structure design field, relates in particular to a kind of cover plate convex closure structure.

Background technology

In communication equipment, there are many electrical connectors, be used for bonding conductor (line) and suitable complementary elements, realize circuit and switch on and off.

In connector screening box assembling parts, the fixing main hangnail structure that adopts of cover plate and support, not loosening to guarantee its left and right directions.

As depicted in figs. 1 and 2, between the fin geometrical clamp at the cover plate of existing connector screening box and top, when assembling, conventionally adopt the structure of hangnail 100.Although it is loosening that hangnail structure can guarantee cover plate and fin geometrical clamp, very high to the accuracy of manufacture requirement of the two, often have and cannot assemble or assemble difficult situation generation.Therefore, can only amplify fit-up gap, but when cover plate and geometrical clamp excesssive gap, the problem that conference causes fixing or producing dislocation, deviation is crossed in its fore-and-aft direction space.So there is the phenomenon that production efficiency is low in prior art.

Therefore, prior art has yet to be improved and developed.

Utility model content

In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cover plate convex closure structure, is intended to solve existing cover plate and fin geometrical clamp fixed form and easily produces dislocation, deviation, problem that production efficiency is low.

The technical solution of the utility model is as follows:

A kind of cover plate convex closure structure, for fin geometrical clamp is fixing on the cover board, wherein, described cover plate convex closure structure comprises some convex closures on the cover board of setting, is arranged on the some through holes on fin geometrical clamp, the adaptive setting in position of described convex closure and through hole, for being arranged at convex closure projection on through hole.

Described cover plate convex closure structure, wherein, described convex closure is set to circular protrusions shape.

Described cover plate convex closure structure, wherein, described through hole is manhole.

Described cover plate convex closure structure, wherein, described convex closure is provided with a plurality of, and is evenly arranged on the side edge of cover plate.

Beneficial effect: the utility model is by the cover board arranging convex closure structure, on fin geometrical clamp, adaptive position arranges through hole simultaneously, thereby guaranteed in plane directive moderate controlled fit-up gap, avoided processing in the situation that has deviation assembling difficult problem, guaranteed again good fixed effect, made stable the fixing of fin geometrical clamp and cover plate.

Embodiment

The utility model provides a kind of cover plate convex closure structure, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

In conjunction with shown in Fig. 3 to Fig. 5, the preferred embodiment of a kind of cover plate convex closure structure of the utility model, it comprises cover plate 300, fin geometrical clamp 400.Improvements of the present utility model are, on described cover plate 300, be provided with some convex closures 210, on described fin geometrical clamp 400, be provided with some through holes 220, the setting position of these convex closures 210 and through hole 220 just in time can make convex closure 210 projections on corresponding through hole 220, utilize such structure, fix cover plate 300 and fin geometrical clamp 400.

Technique effect of the present utility model is: with respect to traditional hangnail structure, convex closure structure of the present utility model processing is very simple, and all can management and control in all directions of cover plate plane, and dismounting is done over again also more convenient.Convex closure of the present utility model has zero offset capability, in the position, hole of through hole, processes in situation devious, and convex closure structure can automatic guiding, there will not be the situation that assembling is difficult.

Further, convex closure 210 of the present utility model is set to circular protrusions shape, correspondingly, described through hole 220 is set to manhole, as shown in Figure 6, like this, fin geometrical clamp 400 can be stablized and be positioned flexibly with cover plate 300, can guarantee that in plane, all directions can have moderate controlled fit-up gap, can avoid again processing the assembling difficult problem causing not in place simultaneously.

Preferably, described convex closure 210 is provided with a plurality of, and is evenly arranged on the side edge of cover plate, example upper end-face edge as shown in Figure 6.

In sum, the utility model is by the cover board arranging convex closure structure, on fin geometrical clamp, adaptive position arranges through hole simultaneously, thereby guaranteed in plane directive moderate controlled fit-up gap, avoided processing in the situation that has deviation assembling difficult problem, guaranteed again good fixed effect, made stable the fixing of fin geometrical clamp and cover plate.

Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection range of the utility model claims.
