Capacitive induction touch-control structure it is complicated, be not easy assembling and it is of high cost the problem of.
Concrete scheme is as follows：
A kind of capacitive induction touch-control structure, including circuit board and display outer cover, it is described display outer cover front on have
Multiple touch areas, it is described display outer cover the back side on there are multiple boss, each boss and a touch area are corresponding, and
And be spaced from each other between multiple boss, the circuit board is equipped with multiple induction electrodes, each induction electrode and a boss phase
Corresponding, the display outer cover is fixedly connected with circuit board, when showing that outer cover is fixedly connected with circuit board, each boss with respectively
Self-corresponding induction electrode is in contact, and the display outer cover and boss are made by plastic material.
Preferably, the plastic material is material of the dielectric constant between 2.0-8.0.
Preferably, the boss is in latticed, to facilitate injection and ensure to be molded quality.
Preferably, the face that the boss is in contact with induction electrode is plane.
Preferably, the area in the face that the boss is in contact with induction electrode is less than or equal to the area of induction electrode.
Preferably, the display outer cover and multiple boss are integrally formed.
Preferably, the periphery of the display outer cover also has the surrounding edge toward the extension of circuit board direction, the height of the surrounding edge
It is identical with the height of boss.
Capacitive induction touch-control structure provided by the utility model has the following advantages compared with prior art：This practicality
The boss on induction electrode and display outer cover that the capacitive induction touch-control structure of new offer passes through circuit board is in contact, its
Middle display outer cover is made of plastic material, therefore by the dielectric constant of display outer cover itself, forms capacitive induction button, no
It is only simple in structure, but also influence of the environment to touch-control is reduced, induced key is more stablized, can also reduce its cost.
Brief description of the drawings
Fig. 1 shows the stereogram of capacitive induction touch-control structure.
Fig. 2 shows the explosive view of capacitive induction touch-control structure.
Fig. 3 shows the schematic diagram at the display outer cover back side.
Embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings is in the utility model exposure
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 1-Figure 3, the utility model provides a kind of capacitive induction touch-control structure, including circuit board 1 and aobvious
Show outer cover 2, there are multiple touch areas 20 on the front of the display outer cover 2, have on the back side of the display outer cover 2 multiple
Boss 24, each boss 24 and a touch area 20 are corresponding, and the circuit board 1 is equipped with multiple induction electrodes 10, each
Induction electrode 10 is corresponding with a boss 24, and the display outer cover 2 is fixedly connected with circuit board 1, when display outer cover 2 and circuit board
1 when being fixedly connected, and each boss 24 is in contact with corresponding induction electrode 10, and the display outer cover 2 and boss 24 are equal
It is made of plastic material.The touch area 20 wherein shown in figure can use the modes such as spraying, silk-screen showing outer cover 2 just
Identified areas is formed on face, showing can be fixedly connected between outer cover 2 and circuit board 1 by screw, riveting column, can also be led to
The mode for crossing clamping realizes that it is fixedly connected, and induction electrode 10 can directly be etched and obtained by the copper foil on circuit board.This practicality
The capacitive induction press-key structure of new offer is in contact by the induction electrode on circuit board and the boss on display outer cover,
Wherein show that outer cover and boss are all made of plastic material, therefore formed by the dielectric constant of display outer cover and boss itself
