Abstract
The utility model relates to a touch key structure. The touch key structure comprises a PCB and a gasket disposed on the PCB, wherein the gasket is provided with a groove hole, and a conducting layer is disposed on the PCB in the groove hole; a metal film is disposed above the gasket; the groove hole is in a round, square, or rectangle shape; the conducting layer is a copper layer, the gasket is a soft rubber layer, and a plastic layer or a glass layer is disposed on the metal film. The touch key structure is simple, and the key can be controlled to open or close through using a finger to touch the metal film and therefore a small deformation is generated, so that the problem of mis-starting of the key caused by the approaching of water or other conductors to the metal film (or touching of the key) is avoided.
Description
Technical field
The utility model relates to a kind of touch control key strcture.
Background technology
Traditional touch key-press structure, surface is plastics or glass, transducer is a sheet metal or covers the copper layer on pcb board, (staff forms a utmost point of capacitor board while touch in the time that hand touches plastics or glass, to form an electric capacity, transducer forms another utmost point of capacitor board), CPU has judged whether touch by detecting this electric capacity.Due to traditional touch key-press structure, be easy to drip to or water pours plastics or glass surface forms electric capacity because of water droplet, cause and touch (action) by mistake.Therefore need a kind of improved touch control key strcture.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, make surface produce miniature deformation by the plastics on finger touch metal decking surface or metallic film or glass surface and change capacitance, can control cut-offfing of button, and there will not be because water droplet drips down or water pours metallic film (touch panel) surface, occur opening by mistake the touch control key strcture that opens button problem.
For achieving the above object, the technical solution of the utility model is: a kind of touch control key strcture, and comprise a pcb board and be arranged on the pad on this pcb board, described pad is provided with a slotted eye, is provided with a conductive layer on the pcb board in described slotted eye; Described pad top is provided with a metallic film.
In the utility model embodiment, described slotted eye is geometry in particular.
In the utility model embodiment, described geometry in particular is circular, square or triangle.
In the utility model embodiment, described conductive layer is a bronze medal layer.
In the utility model embodiment, described pad is a flexible glue layer.
In the utility model embodiment, described metallic film top is also provided with a plastic layer.
In the utility model embodiment, described metallic film top is also provided with a glassy layer.
Compared to prior art, the utlity model has following beneficial effect: the utility model is simple in structure, make surface produce miniature deformation by the plastics on finger touch metal decking surface or metallic film or glass surface, can control cut-offfing of button, and there will not be because water and other conductors come close to or in contact with metallic film (touch panel) surface, occur opening by mistake the problem that opens button; And metallic film of the present utility model can adopt metal decking to replace.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is specifically described.
As Figure 1-4, a kind of touch control key strcture of the present utility model, comprises a pcb board 1 and is arranged on the pad 4 on this pcb board, described pad 4 is provided with a slotted eye 7, is provided with a conductive layer 2 on the pcb board 1 in described slotted eye 7; Described pad 4 tops are provided with a metallic film 5.
Button can be made as various geometries as required, and described slotted eye 7 is geometry in particular; Described geometry in particular is circular, square or triangle.
In the present embodiment, described conductive layer 2 is a bronze medal layer.
In order to ensure that metallic film 5 and conductive layer 2 have certain interval, and can produce miniature deformation, described pad 4 is a flexible glue layer.
In the present embodiment, described metallic film 5 tops are also provided with a plastic layer or glassy layer 3,6.(this metallic film 5 and the flexible plastics layer above this metallic film 5 or glassy layer 3,6 can adopt thin metal layer to replace)
Touch control key strcture of the present utility model can be applicable on the control panel of electronic constant-temperature water faucet and electronic thermostatic shower, thoroughly solve touch-control product and meet the ineffective problem of water, on existing market, touch-control product contact panel has water or water to splash (drip or drench) all can have misoperation or be failure to actuate (be mainly can form an electric capacity while touching plastics or glass due to traditional touch control key strcture by staff or other conductor, and cause opening by mistake of button to be opened) to contact panel.And the utility model, not only there will not be because water droplet is to metallic film (contact panel) surface, occur opening by mistake the problem that opens button, and the utility model makes surface generation miniature deformation by finger touch metallic film (contact panel), can control cut-offfing of button.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function producing does not exceed the scope of technical solutions of the utility model, all belong to protection range of the present utility model.
