The keyboard film circuit board connecting terminal fixing device of the utility model combines the connecting terminals through the neck by providing the neck at the base board corresponding connecting end, which guarantees electric connection among each layer of film circuit boards, simplifies the keyboard structure and is convenient for installation, thereby the utility model improves installation efficiency.
Description
Technical field
The utility model is meant a kind of keyboard film circuit board link fixed structure especially about a kind of keyboard film circuit board.
Background technology
Along with the development of information technology, various electronic products are widely applied in daily life and the work, for example computer.And keyboard also uses widely because of a kind of typical input equipment as electronic product.General keyboard comprises: loam cake is provided with opening; Lower cover can be fixed by plurality of fixed device and loam cake; The keyboard group is contained in the opening of loam cake; And the film circuit board group, be located between keyboard group and the lower cover by positioner.
Usually, the base material of film circuit board is soft plastic (polyester, a polyimides etc.), the about 0.05mm～1mm of thickness, at its one or both sides coated with circuit layer to form the printed circuit system.The film circuit board group that existing keyboard uses comprises upper and lower layer film circuit board and is arranged on dividing plate between the upper and lower layer film circuit board.Each layer film circuit board is provided with a link, and these links are coupled together to realize the electric connection of each layer film circuit board.Existing link generally can link together conductively by conducting resinl, perhaps docks then bending by the link with the upper and lower circuit plate, be fixed in again that the keyboard upper and lower cover is equipped with on structure.Yet this fixed form need be provided with against structure on upper and lower cover, makes keyboard structure become complicated, has also increased the difficulty of assembling simultaneously, has reduced packaging efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of keyboard film circuit board link fixed structure, and it is by being provided with the link that draw-in groove fixes film circuit board on base plate, thereby has simplified the packaging efficiency of keyboard structure and raising.
For being implemented in above-mentioned purpose, the utility model provides a kind of keyboard film circuit board link fixed structure, comprise upper and lower layer film circuit board and base plate, levels film circuit board correspondence is provided with one group of link, and this base plate is provided with can be with the draw-in groove that fixes after the link bending.
Described keyboard film circuit board link fixed structure wherein, also comprises the dividing plate that is located between the upper and lower layer film circuit board.
Described keyboard film circuit board link fixed structure, wherein, base plate is a metallic plate, draw-in groove is a shape.
Described keyboard film circuit board link fixed structure, wherein, draw-in groove is made by punching press.The utility model keyboard film circuit-board connecting structure is by being provided with draw-in groove so that link can be fastened togather by draw-in groove with the corresponding link of base plate, guarantee the electric connection between each layer film circuit board, simplify keyboard structure, and be convenient to assembling, thereby improved packaging efficiency.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
Brief description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.
In the accompanying drawing,
Fig. 1 is the three-dimensional exploded view of the utility model keyboard film circuit board link fixed structure;
Fig. 2 is the unit assembly drawing of Fig. 1;
Fig. 3 is the constitutional diagram of Fig. 1.
Embodiment
For further setting forth the utility model is technological means and the effect that the predetermined purpose of realization is taked, see also following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and characteristics, should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.
Consult Fig. 1 and Fig. 2, it is the three-dimensional exploded view of a kind of embodiment of the utility model keyboard film circuit board link fixed structure.The utility model keyboard film circuit board link fixed structure comprises: topmost thin film circuit board 2, lower film circuit board 4, be located at the dividing plate 6 between the upper and lower layer film circuit board 2,4 and be located at the base plate 8 of lower film circuit board 4 belows.Thereby upper and lower layer film circuit board 2,4 is respectively equipped with leading-out terminal 20,40 for externally connecting the output keyboard signal, and on upper and lower layer film circuit board 2,4 also respectively correspondence be provided with two groups of links 21,41,22,42,6 pairs on dividing plate should be provided with perforate 61 by first group of link 21,41, so that the link 21 of topmost thin film circuit board 2 electrically conducts by the link 41 of perforate 61 with lower film circuit board 4.Second group of link 22,42 stretches out respectively outside the dividing plate 6 and can directly contact, and base plate 8 corresponding second group of link 22,42 are provided with draw-in groove 81, and in the present embodiment, base plate 8 is a metallic plate, and this draw-in groove 81 is stamped to form, and is a shape.First group of link 21,41 can link together conductively by conducting resinl, and second group of link 22,42 directly dock so that the corresponding connection of the circuit of link, bending then, make and produce pressure in the bending place, lower film circuit board 2, second group of link 22 of 4,42 directly contact, thereby in the realization, lower film circuit board 2, second group of link 22 of 4,42 direct connection, for making two groups of links 21,41,22,42 are in good bending state to guarantee its good electric connection, link 22 after will bending again, 42 stretch in the draw-in groove 81 of base plate 8, and it is sticked in the draw-in groove 81.
The utility model keyboard film circuit-board connecting structure is by being provided with draw-in groove 81 with base plate 8 corresponding second group of link 22,42, make second group of link 22,42 to be fastened togather by draw-in groove, guarantee the electric connection between each layer film circuit board, thereby guarantee the normal use of keyboard.Being provided with of this draw-in groove 81 is simple, has simplified keyboard structure, and is convenient to assembling, thereby has improved packaging efficiency.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model accompanying Claim.
