Though it can satisfy the requirement of basic even back diffusion this kind structure, but in practical application, (thickness of rubber layer 5 is about 2mm because this rubber layer 5 has thicker thickness with respect to other assembly, and the thickness of light guide plate 40 is about 0.125mm), cause its whole combination thickness to be difficult for reducing, therefore be unfavorable for miniaturization, the sophistication design of Related product, its whole competitiveness also is difficult to promote.
Novel content
Main purpose of the present utility model is to provide a kind of keyboard back light composite set, and the integral thickness that it can effectively reduce after the assembling is easy to the design of product employing than sophistication.
Another purpose of the present utility model is to provide a kind of keyboard back light composite set, and it has less composition assembly and easy assembly program, can effectively reduce production costs.
The utility model is for achieving the above object and effect, the technical scheme that it adopted is, a kind of keyboard back light composite set, and it comprises: circuit board, table side at this circuit board is provided with several shell fragments, and between each shell fragment or the circuit board outside (figure does not show) be provided with the light source body; Several buttons, the tool light transmission is arranged at a side of this circuit board tool shell fragment and corresponds respectively to each shell fragment position; Sheet material (can be reflecting piece, diffusion sheet, silver-colored net), this sheet material tool reflective or diffusivity or ground connection property are arranged between this circuit board and each button, are provided with several storage tanks on this sheet material, can distinguish the light source body on corresponding ccontaining this circuit board; One light guide plate, tool is led optical activity, is located between this sheet material and each button, and its surface is provided with the processing district and needs transmission region corresponding to each button, and then is provided with several storage tanks between each processing district, can distinguish the light source body on corresponding ccontaining this circuit board.
From the above mentioned as can be known, keyboard back light composite set of the present utility model, omitted the rubber layer in the existing keyboard back light combining structure, thereby has the effect that reduces product mix thickness really, and, can effectively reduce production costs because of it has less composition assembly and easy assembly program.
