Description
Technical field
The utility model relates to circuit boards, more specifically to a kind of button circuit board.
Background technique
TV is the necessary article in life, but when seeing TV, often may feel that there are many key on remote controler, this
For old man or child be it is very inconvenient, sometimes accidentally enter some operation interface without knowing how to return
It returns.
Utility model content
The technical problem to be solved by the present invention is in view of the drawbacks of the prior art, provide a kind of button circuit board.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of button circuit board is constructed, key point
It is not that VOL+, VOL-, CH+, CH-, MENU, SOURCE, power supply can be manipulated directly with keypad when not using remote controler
TV, realization adjusting volume+-, tune program channel+- the effects of.
In button circuit board described in the utility model, the button circuit board includes pcb board, the pcb board front
Equipped with PET key film, the back side is equipped with contact pin connector, 3M double-sided adhesive.
In button circuit board described in the utility model, the contact pin connector spacing is 8PIN/1.25mm.
In button circuit board described in the utility model, the PET key film specification is 113.5*10mm, is equipped with PET
Contiuum type touch key, a height of Aria12.2 color 877C silver color of key word, each key center spacing is 15.5mm, affiliated
Material is black PVC, the PET key film strips 3M gum.
In button circuit board described in the utility model, the pcb board is dual platen, model CX-DLED-4017-
KEY VER1.0 CQG40926, specification 113*9.4*0.6mm.
In button circuit board described in the utility model, the button circuit board uses FR-4 plate, has good
Mechanical strength.
In conclusion being designed using above-mentioned button circuit board, the utility model uses FR-4 plate, has good machinery
Intensity.The PET key film is equipped with PET Contiuum type touch key, has good leakproofness and antioxygenic property, can ensure that just
It is used for a long time under normal environment.The utility model uses simply, easily operated.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is a kind of button circuit board front schematic view of the utility model
Fig. 2 is a kind of button circuit board schematic rear view of the utility model
Fig. 3 is a kind of button circuit board circuit diagram of the utility model
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, 2, a kind of button circuit board 100 described in the utility model includes pcb board 1, and the pcb board 1 is just
Face is equipped with PET key film 2, and the back side is equipped with contact pin connector 3,3M double-sided adhesive 4.
Further, 3 spacing of contact pin connector is 8PIN/1.25mm.
Further, 2 specification of PET key film is 113.5*10mm, is equipped with PET Contiuum type touch key 21, described
The a height of Aria12.2 color 877C silver color of key word, each key center spacing are 15.5mm, and said material is black PVC, described
PET key film strips 3M gum.The PET key film is equipped with PET Contiuum type touch key, has good leakproofness and anti-oxidant
Performance can ensure that and be used for a long time under normal environment.
Further, the pcb board 1 is dual platen, model CX-DLED-4017-KEY VER1.0CQG40926, rule
Lattice are 113*9.4*0.6mm.
Further, the button circuit board 100 uses FR-4 plate, has good mechanical strength.
The requirement Xiang of the button circuit board 100 arrives+60 DEG C, uses temperature to Shi Du≤80%, storage temperature -10
0 to 40 DEG C, assembly and transportational process pay attention to antistatic process, when assembly, plank not made to deform or distortion, not under pressure, with
Exempting from board deformable squeeze causes element to fall off and damage by pressure, and complete machine internal wirings are reasonable, and wiring is secured.Wiring is tried not from dry
Big object is disturbed to pass through, such as Switching Power Supply, backlight constant-current source etc., in case push button signalling is disturbed.In order to which complete machine reaches better
EMC effect, it is proposed that connection uses twisted wire mode between mainboard, conditional to take shielding line and close to mainboard end
Magnet ring is put on line.
Finger is placed on position among 21 bulge of key and presses, its institute when pressing the button 21 and normally contacting with PCB Gold plated Layer
Corresponding line-to-ground resistance value belongs to normally within 10 Europe.The external wire rod of the button circuit board 100 is in 25cm length.
Although being disclosed by above embodiments to the utility model, the protection scope of the utility model not office
It is limited to this, under conditions of conceiving without departing from the utility model, deformation, the replacement etc. done to above each component will fall into this
In the scope of the claims of utility model.
