Abstract

The utility model provides a novel illuminant keyboard structure, which from up to down comprises a light-transmitting key cap, a scissor-shaped leg, an elastic rubber cap, an upper layer line film, a middle layer line film, a lower layer line film and an aluminum plate. The novel illuminant keyboard structure is characterized in that a LED chip is fixed on the lower layer line film in a position corresponding to the light-transmitting key cap, and the LED chip is equipped with conductive bumps which are pressed into lower layer lines; and that through holes are respectively arranged in the lower layer line film and the upper layer line film in positions corresponding to the LED chip, so that lights emitted by the LED chip can pass through the through holes and reach the light-transmitting key cap. The cost of the keyboard structure is low, the illumination of the keyboard structure is even, and the thickness of the whole keyboard is reduced.

Description

The novel light-emitting keyboard structure

Technical field

The utility model is specifically related to a kind of illuminated keyboard structure.

Background technology

Therefore the LGP illuminated keyboard receives a lot of users' welcome owing to can under the situation of no light, use.But the cost cost of traditional LGP illuminated keyboard own is high; And only around film circuit board, arrange led light source; Causing whole keyboard luminous is not very evenly to coil, and therefore producing a kind of low cost and luminous uniform illuminated keyboard is the direction that each production firm makes great efforts.

Summary of the invention

The utility model provides a kind of illuminated keyboard structure, and purpose is to solve the prior art problem, provides a kind of cost cost low and luminous uniform illuminated keyboard structure.

The utility model technical scheme that adopts of dealing with problems is:

The novel light-emitting keyboard structure comprises transparent keycap, scissors pin, elastic caoutchouc cap, upper layer circuit film, middle level insulation film, lower floor's line film, aluminium sheet successively under last.The fixed-site of corresponding each transparent keycap has a led chip on lower floor's line film, and the conductive salient point that led chip is provided with is pressed in lower floor's circuit; The position of corresponding led chip offers through hole respectively on middle level insulation film and upper layer circuit film, and the light that led chip sends passes above-mentioned two through holes to transparent keycap.

The outer insulation transparent glue-line that coats of said led chip.

The beneficial effect of the utility model: the utility model has reduced the use of LGP, reduces the cost of keyboard, and a led chip all is installed below each keycap, makes whole keyboard luminous evenly.And in this patent led chip directly is fixed on lower floor's line film, do not have the thickness of the whole keyboard of extra increase, so the keyboard integral thickness of this structure reduces.

Fig. 1 is the cutaway view of the utility model;

Fig. 2 is the assembling sketch map of the single button of the utility model;

Fig. 3 is the syndeton sketch map of led chip and lower floor's line film.

Among the figure: 1. transparent keycap, 2. scissors pin, 3. elastic caoutchouc cap, 4. upper layer circuit film, 40. through holes, 5. middle level insulation film, 50. through holes, 6. lower floor's line film, 7. aluminium sheet, 8.LED chip, 9. conductive salient point, 10. lower floor's circuit, 11. insulation transparent glue-lines, 12. upper strata button point circuits, 13.LED chip circuit, 14. lower floor's button point circuits

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.

Novel light-emitting keyboard structure shown in Fig. 1, Fig. 2, Fig. 3 comprises transparent keycap 1, scissors pin 2, elastic caoutchouc cap 3, upper layer circuit film 4, middle level insulation film 5, lower floor's line film 6, aluminium sheet 7 successively under last.The fixed-site of corresponding transparent keycap 1 has led chip 8 on lower floor's line film 6, and the conductive salient point 9 that led chip 8 is provided with is pressed in lower floor's circuit 10.For the light that led chip 8 is sent arrives transparent keycap 1; The position of corresponding led chip offers through hole 50,40 respectively on middle level insulation film 5 and upper layer circuit film 4; The light rays that led chip 8 sends is passed through hole 50,40 to transparent keycap 1, and sees through transparent keycap 1.

In order to make the led chip 8 can firm being fixed on lower floor's circuit 10, and protection led chip 8 suffer damage coating one insulation transparent glue-line 11 led chip 8 outside.In order to satisfy the demand of client to colored light, can in substratum transparent 11, add fluorescent material with color etc., also can transparent keycap 1 be made colored.

Wherein every LEDs chip 8 routes to out the PIN position with each button point process on lower floor's line film 6; Upper strata button point circuit 12 as shown in Figure 2, led chip circuit 13, lower floor's button point circuit 14; The led chip power supply is provided; Illuminate each keycap character effect to reach, but make at light in the more weak or dark surrounds all flexible operating keyboards.

Compare with traditional LGP illuminated keyboard; Because of traditional LGP illuminated keyboard cost cost is high, and only around film circuit board, arrange LED, it is not very even causing whole keyboard luminous; And this new structure is under each button, all to place a LEDs luminescence chip; Solved the problem of whole keyboard non-uniform light, the LED luminescence chip is cheap in addition, and the consumer is accepted.
