Description
Technical field
This utility model belongs to thin film switch, is specifically related to a kind of antistatic film switch.
Background technology
Along with the continuous expansion of thin film switch market application, its technology in every profession and trade requires also to improve constantly.Be widely used in the industries such as industrial equipment due to thin film switch, therefore in some forceful electric power applied environments, client is also improving constantly for the requirement of thin film switch antistatic, and particularly to the antistatic at Product Windows, technology requires the highest.And at present the Conventional membrane switches in industry is all unable to reach this requirement, and also without Related product and technical identification.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of antistatic film switch, effectively to solve the antistatic problem at the window of thin film switch.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that:
A kind of antistatic film switch, including the primer layer pasted the most successively, lower line layer, line key layer, electrostatic layer, face key layer, panel layer, lower line layer is provided with switch key sheet, panel layer is provided with transparent window, face key layer below transparent window, electrostatic layer, line key layer, lower line layer, corresponding hole is had on primer layer, the position of the corresponding described switch key sheet in described panel layer surface has lobe, the position of described key layer described switch key sheet corresponding with described line key layer has through hole, it is characterized in that: in the hole of described key layer, be provided with transparent conductive sheets, thin film switch ground connection are drawn in electrostatic layer one end, transparent conductive sheets conducts electricity stickup respectively mutually with transparent window and electrostatic layer.
Described transparent conductive sheets upper surface is provided with OCA optical cement, and mutually bonding with transparent window by OCA optical cement.
The hole periphery of described electrostatic layer is provided with conducting resinl, and mutually bonding with transparent conductive sheets by conducting resinl.
Described transparent conductive sheets is ITO electro-conductive glass sheet.
The exit of described electrostatic layer is provided with ground hole, is connected with the earth lead on pcb board or metal chassis by ground hole.
Or described electrostatic layer is aluminium foil or aluminium wire netting copper mesh.
Use antistatic film of the present utility model to switch, have the advantage that
1, by arranging a transparent conductive sheets in the hole of face key layer, and conducting resinl is crossed by electrostatic Netcom it is connected with transparent conductive sheets, thus play the anti-static effect at window, and also ensure that the transparency of window；
2, significantly improve the antistatic grade of product transparent window, enable product effectively to apply in the higher occasion of electrostatic.
3, simple in construction, easy to make, it is possible to significant economic benefit can be brought for enterprise.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of antistatic film of the present utility model switch.
Detailed description of the invention
Antistatic film of the present utility model switch as it is shown in figure 1, same as the prior art, primer layer 1 that it is pasted the most successively, lower line layer 2, line key layer 3, electrostatic layer 9, face key layer 4, panel layer 5.Primer layer 1, line key layer 3, face key layer 4 are tacky on two sides, and primer layer 1 bottom surface Pasting is on the pcb board of product, and lower line layer 2 is provided with switch key sheet 6.The position of the corresponding switch key sheet 6 of panel layer 5 has lobe 51, and on line key layer 3, face key layer 4, the position of corresponding switch key sheet 6 has through hole.Panel layer 5 is provided with transparent window 7, and face key layer 4 below transparent window 7, electrostatic layer 9, line key layer 3, lower line layer 2, primer layer 1 have corresponding hole.Unlike the prior art, a transparent conductive sheets 8 it is provided with in the hole of face key layer 4, thin film switch ground connection are drawn in electrostatic layer 9 one end, and the transparent window 7 phase stickup of transparent conductive sheets 8 and top, and the edge, hole of the edge of transparent conductive sheets 8 and electrostatic layer 9 conducts electricity stickup mutually.
Transparent conductive sheets 8 upper surface is provided with OCA optical cement 10, and mutually bonding with transparent window 7 by OCA optical cement 10.
The edge, hole of electrostatic layer 9 is provided with conducting resinl 11, and mutually bonding with transparent conductive sheets 8 by conducting resinl 11.
In the present embodiment, transparent conductive sheets 8 uses the ITO electro-conductive glass sheet with high transmission rate, definition and conductive characteristic, certainly may be used without the material of other similar performance.
The concrete earthing mode of electrostatic layer 9 can use and arrange a ground hole 12 on exit, is connected with the earth lead on pcb board or metal chassis by ground hole 12.
Electrostatic layer 9 uses aluminium foil, it would however also be possible to employ other similar conductive material, or such as aluminium wire netting copper mesh.
In sum, antistatic film of the present utility model switchs, by pasting the electrostatic net of one layer of ground connection above lower circuit, one transparent conductive sheets 8 is set in the hole of face key layer 4, and conducting resinl 11 is crossed by electrostatic Netcom fit with transparent conductive sheets 8, thus play the anti-static effect at window, also ensure that the transparency of window simultaneously.Tests prove that, antistatic film of the present utility model is used to switch, the antistatic grade of product transparent window 7 can be significantly improved, product is enable effectively to apply in the higher occasion of various electrostatic, and it is simple in construction, easy to make, can can bring significant economic benefit for enterprise, prospect is the most wide.
But, those of ordinary skill in the art will be appreciated that, above embodiment is intended merely to this utility model is described, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, change, the modification of embodiment described above all will be fallen in Claims scope of the present utility model.
