Description
Technical field
This utility model relates to a kind of touch control key strcture, is specifically related to a kind of touch control key strcture with conductive layer.
Background technology
Ordinary appliances has the most all used touch control button at present, and it progressively instead of relevant mechanical key in the past.As shown in figs. 1 to 6, and present touch controlled key modular construction includes PCB 1 and keycap 2, PCB 1 is provided with the Copper Foil tactile disk 11 identical with keycap 2 quantity, is provided with LED 12 in the middle part of Copper Foil tactile disk 11, keycap 2 covers on Copper Foil tactile disk 11, and keycap 2 top is provided with light-transparent pattern 21.Described keycap 2 is plastics keycap, it it is the contact panel 3 of electrical equipment outside it, contact panel 3 is shell or some single perspex panel of electrical equipment, user is by touching contact panel 3, the human body electric field effect of user, forming capacitive induction, PCB 1 investigates trickle curent change by Copper Foil tactile disk 11 and touch chip circuit, thus triggers corresponding button operation and control.Owing to the contact panel 3 outside described keycap 2 is mostly the shell of electric equipment products, also has plenty of independent printing opacity plastic parts, the fault of construction of existing touch control key strcture causes keycap and the contact panel can not be the thickest, not so there will be sensing less than, touch unresponsive phenomenon.But, the electrical equipment the most special or complicated for some shapes and equipment, its sensitivity of existing touch control key strcture is the lowest, it is difficult to meet application requirement.
Utility model content
The purpose of this utility model is for the problems referred to above weak point, it is provided that a kind of Novel touch control button, and it by keycap is increased conductive layer, increases induction area, improves induction sensitivity and increase induction region, expanding the range of touch controlled key.
In order to achieve the above object, this utility model is by the following technical solutions:
Novel touch control button, including PCB and keycap, keycap top is provided with light-transparent pattern, and the outer surface of described keycap is provided with a conductive layer, and described keycap top is positioned at outside conductive layer, and to be additionally provided with one pigment coated.
Preferably, the position of described conductive layer correspondence light-transparent pattern is provided with and dodges hole.
Specifically, described conductive layer is metal powder conductive layer.
The most concrete, described conductive layer is copper powder conductive layer；Or, described conductive layer is argentum powder conductive layer；Or, described conductive layer is aluminium powder conductive layer；Or, described conductive layer is iron powder conductive layer.
This utility model Novel touch control button, it by keycap is increased conductive layer, increases induction area, improves induction sensitivity and increase induction region, expanding the range of touch controlled key.

Below by way of the drawings and specific embodiments, this utility model is described further:
Detailed description of the invention
As shown in FIG. 7 and 8, Novel touch control button described in the utility model, including PCB 1, keycap 2 and contact panel 3, this utility model increases conductive layer 22 and pigment coated 23 to keycap innovatively, improves the attractive in appearance of button while increasing touch-control sensing sensitivity further.Concrete structure is as follows:
Described keycap 2 top is provided with light-transparent pattern 21, and light-transparent pattern 21 is the functional pattern of button, such as shutdown pattern, wifi indicia patterns, the pattern that volume plus-minus pattern etc. is arranged according to actual needs.
The outer surface of described keycap 2 is provided with a conductive layer 22 (outer surface of keycap includes keycap end face, side and the back side), and specifically, described conductive layer 22 is metal powder conductive layer.The most concrete, described conductive layer 22 is copper powder conductive layer；Or, described conductive layer 22 is argentum powder conductive layer；Or, described conductive layer 22 is aluminium powder conductive layer；Or, described conductive layer 22 is iron powder conductive layer.Above-mentioned metal powder conductive layer is combined with keycap 2 body by the way of spraying plating.
Further, in order to make button more aesthetically pleasing, meeting the outward appearance collocation of product, described keycap 2 top is positioned at outside conductive layer 22 and is additionally provided with one pigment coated 23, and described pigment coated 23 are attached to outside conductive layer 22 by the way of secondary sprays.
In order to make the light-transparent pattern 32 of keycap 2 to clearly indicate, the position of the corresponding light-transparent pattern 21 of described conductive layer 22 is provided with dodges hole 221.Described dodge hole 221 can by spraying plating conductive layer 22 when by block reserved by the way of realize, or the overall spraying plating of conductive layer 22 can also be waited to realize by the way of laser carving after completing.
Below by way of detailed description of the invention, this utility model is further described:
When user removes to touch the contact panel 3 above keycap 2 with finger, owing to this utility model covers one layer of conductive layer 22 at keycap 2 outer surface, can sense human body electric field to larger area, i.e. improve and sense sensitivity and induction region, electric capacity is constituted with the Copper Foil tactile disk 11 in following PCB 1, form capacitive touch-control circuit, thereby produce the movement of electric charge, then detected by the touch chip circuit in PCB 1.Owing to keycap 2 increases conductive layer 22, thus improve induction area and sensitivity, such keycap, can be made the thickest, considerably beyond the spacing of the most common touch controlled key, it is suitably applied the body structure of various complexity, increases the suitability of touch controlled key application scenario.
This utility model Novel touch control button, it by keycap is increased conductive layer, increases induction area, improves induction sensitivity and increase induction region, expanding the range of touch controlled key.
