Specific embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
To keep the contents of the present invention more obvious and easy to understand, done further below in conjunction with attached drawing 1- Fig. 6 and specific embodiment
Description.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
As shown in Figure 1, the touch key-press plate in the present embodiment, including the touch tablet 1 as main body and as key
Conductive metal film 5, touch tablet and conductive metal film constitute complete touch key-press plate after being assembled together.
As shown in Figure 1,1 main body of touch tablet preferentially uses pcb board as substrate, which can be circle, square,
The shapes such as rectangle, the pcb board are doubling plate, and front is disposed with multiple touch sensible points 2, and the size of each point onboard is half
The circle of diameter 1mm is arranged by the distance of 10mm in length and breadth between each point.The back side is the cabling and control electricity of corresponding touch sensible point
Road.
It is overleaf the cabling and control circuit of corresponding touch sensible point in the present embodiment, cabling described herein and control
Circuit processed is known technology in the art, identical as the cabling of general traditional touch key-press plate and control circuit.
As shown in Figures 2 and 3, it is exposed if touching induction point, after being touched or there is induction amount, may cause mistake
Touching, therefore need to stick cover plate 3 to prevent from accidentally touching on each induction point；The structure of cover plate is divided into three layers, and one layer is double-sided adhesive
3-1 (cover plate is sticked together by double-sided adhesive and touch sensible point), one layer be shielding action conductive material 3-2, conduction material
There is one layer of insulating materials 3-3 on material surface, and each touch sensible, which is selected, has a cover plate 3 to be covered on 2.
As shown in figure 4, conductive metal film 5, is made of, it is ensured that this layer layer of metal film 5-1 and one layer of conductive double sided adhesive tape 5-2
Metal film has longitudinal electric conductivity.This layer of metal conductive film can reduce out arbitrary dimension with scissors.User according to oneself
It needs, reduces out suitable metal conductive film, then take the cover plate of corresponding position off, the metal conductive film reduced is pasted
It goes, thus constitutes a complete touch key-press control panel.
The production method that the present invention also proposes a kind of touch key-press plate, includes the following steps:
Step 1) makes the touch tablet as main body, selects double-layer PCB board as substrate, and multiple touchings are arranged in substrate front side
Induction point is touched, control circuit is constituted to each touch sensible point arrangement cabling in substrate back；
Step 2) is selected in each touch sensible of substrate front side pastes cover plate；
Step 3) makes the conductive metal film as key；
Step 4) assembles touch tablet and conductive metal film according to setting button is required；It will be pasted on touch sensible point
Cover plate is torn, and conductive metal film is pasted on touch sensible point.
Embodiment 1
We are further illustrated with the design of the square touch keypad of a side length 70mm.
On this plate, we can arrange 6*6 touch sensible point, the transverse direction of each touch sensible point, fore-and-aft distance
For 10mm (center away from), distance of each touch sensible point apart from Edge Distance at least more than 5mm.If this level of sense
It should put and expose, after being touched or there is induction amount, may cause and accidentally touch.Therefore it needs to stick lid on each induction point
Piece (as shown in Figure 2) is to prevent from accidentally touching.Each touch sensible has been selected a cover plate and has been covered with.
Assuming that we need to design five keys, a draw runner on this touch tablet.Touch key-press and draw runner can be used
The tools such as scissors are hung on large stretch of conductive metal film (side view that Fig. 4 is conductive film) and cut out shape.The size of touch key-press
Generally less than 10mm*10mm, square, rectangle, circle, triangle etc. all may be used.The shape of draw runner designs as shown in figure 5, every
A draw runner is at least made of 3 same patterns.The cover plate for tearing corresponding position will be attached to by the conductive film of key block and draw runner block
Corresponding induction point, a touch control board just complete as shown in Figure 6.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
Various changes can be made in the form and details for it.
