Description
Technical field
The utility model relates to a kind of backlight keyboard.
Background technology
when insufficient light, manipulation can connect the electronic product of keyboard, we need the keyboard adopting automatic light source system, and the keyboard of common automatic light source generally has two kinds, a kind of is directly light is radiated on the button on keyboard by being arranged on the light source arranged under each button of keyboard, the shortcoming of this keyboard is the power source connection system that need arrange this light source in keyboard in addition, make keyboard complicated integral structure and become heavy abundant, using inconvenience; Another kind of then be that light guide plate is set by the inside at keyboard, again light source is set in described light guide plate, thus by light guide plate the light of this light source reflexed on the button on keyboard, the light source be required to be equally in light guide plate of this keyboard arranges power source connection system in addition, makes keyboard complicated integral structure, heaviness and abundant.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides the backlight keyboard of simple, the overall frivolous and good illumination effect of a kind of structure.
The technical scheme that the utility model adopts is: the utility model comprises silica gel push-button, flexible PCB, light guide plate and metal base plate, described silica gel push-button, flexible PCB, light guide plate and metal base plate are combined by double-sided adhesive sheet successively, described flexible PCB is provided with leading-out terminal, the bottom of described flexible PCB is also provided with several bonded LED lamps, and described bonded LED lamp is connected with described leading-out terminal.
Described flexible circuit board comprises leading-out terminal, and described leading-out terminal comprises leading-out terminal I and leading-out terminal II, and one end of described leading-out terminal I and described leading-out terminal II is connected with described flexible PCB respectively, and the other end then extends to the outside of described flexible PCB.
Described light guide plate comprises light-passing board and reflectance coating, and described reflectance coating is arranged on the lower surface of described light-passing board by described double-sided adhesive sheet.
Described reflectance coating is provided with waterproof ventilated membrane.
Described flexible circuit board also comprises button golden finger, and described button golden finger is arranged on the position corresponding with described silica gel push-button, and described button golden finger is corresponding one by one with the button on described silica gel push-button.
The beneficial effects of the utility model are: due in the utility model, in the bottom surface of flexible PCB, bonded LED lamp is set, and on described flexible PCB, there is leading-out terminal, described bonded LED lamp is connected with described leading-out terminal by described flexible PCB, described flexible circuit board also comprises button golden finger, and described button golden finger is corresponding one by one with the button on described silica gel push-button.So the power source connection system of light source of the present utility model relative to the light source of backlight keyboard in the past connected system structurally more simply, more frivolous on the whole, and simple internal structure makes the propagation of the light of light source in inside of the present utility model not by unnecessary stop and loss, makes illumination effect of the present utility model better.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises silica gel push-button 1, flexible PCB 2, light guide plate, metal base plate 3 and button golden finger.
Described flexible PCB 2 includes leading-out terminal 5, described leading-out terminal 5 comprises leading-out terminal I 51 and leading-out terminal II 52, one end of described leading-out terminal I 51 and leading-out terminal II 52 is connected with described flexible PCB 2 respectively, and the other end then extends to the outside of described flexible PCB 2.
The bottom of described flexible PCB 2 is also provided with several bonded LED lamps, and the quantity of described bonded LED lamp is determined according to actual conditions, and described bonded LED lamp is connected with described leading-out terminal 5 by described flexible PCB 2.
Described light guide plate comprises light-passing board 6 and reflectance coating 7, and described reflectance coating 7 is arranged on the lower surface of described light-passing board 6 by described double-sided adhesive sheet, and described reflectance coating 7 is also provided with waterproof ventilated membrane 8, breathing freely for inside of the present utility model.
Described silica gel push-button 1, flexible PCB 2, light guide plate and metal base plate 3 double-sided adhesive sheet 4 successively by transparent is combined.
The upper surface being attached thereto that described button golden finger is then arranged on described flexible PCB 2 connects, described silica gel push-button 1 is arranged on the top of described button golden finger, key on described button golden finger is corresponding one by one with the button on described silica gel push-button 1, by pressing described silica gel push-button 1, and then push away the key mapping making correspondence on flexible PCB 2 described in the conducting of described button gold hand.
During use, described leading-out terminal 5 is connected with the socket matched of peripheral control unit, and by the control of described controller, described bonded LED lamp electrified light emitting, after light-passing board 6 described in light therethrough, reflect through described reflectance coating 7 again, then be incident upon on described silica gel push-button 1 through described light-passing board 6.
The utility model is applicable to backlight keyboard and manufactures field.
