Abstract
The utility model is an improvement to film key-press structure, whose structure comprises a metal spring leaf, an insulating layer, and a conductive layer formed on the insulating layer. Wherein, the insulating layer continuously covers on the metal spring leaf. The insulating layer is connected with the metal spring leaf through an adhesive layer. The conductive layer is made of aluminum, which is an aluminum evaporated layer that is continuously formed on the insulating layer through evaporation.
Description
Technical field
The utility model relates to a kind of key switch, and especially the sort of use has the film key switch of the film of aluminium-vapour deposition layer as conductive surface layer.
Background technology
Common film key structure in the located by prior art, a kind of " tool travelling contact film and the thin film switch " that discloses in No. 090116890 patent of TaiWan, China for example, its structure mainly is by dome-type travelling contact, covers the travelling contact upper surface and scribble the insulation film of solid on the travelling contact lower surface, and the partition of pasting on the insulation film lower surface constitutes.This structure can reach insulation and reach the fixedly effect of travelling contact position.If the film key structure has generation of static electricity in use, can on the insulation film surface, print one deck money base matter coating, thus, the static that is produced during operation push-button can be by the metal level on surface by dead ground, and can not have influence on the function of travelling contact, and do not need to install in addition earthing device.But, the film key of Gou Chenging in the above described manner, the step pogoniasis of its metal level printing just can be carried out later at the applying insulation film, and this causes the complexity of processing procedure.Moreover, metal level with the formation of money base matter coating, its tack, density are all not good, after face contact repeatedly impression appears or phenomenon such as come off easily, make the ground connection effect reduce, if come the reinforced metal layer in the mode that increases thickness, the puzzlement that can cause film key structural entity thickness to increase again.
Summary of the invention
The purpose of this utility model is to be to provide a kind of thin film press button structure improvement, by improvement of the present utility model, with tack, the packing of improving the aluminium-vapour deposition layer, avoids coming off.
The purpose of this utility model is to be to provide a kind of thin film press button structure improvement, by improvement of the present utility model, to simplify processing procedure, to reduce production costs.
The purpose of this utility model is to be to provide a kind of thin film press button structure improvement, by improvement of the present utility model, improves the intensity of aluminium-vapour deposition layer, prevents improper destruction.
The purpose of this utility model is to be to provide a kind of thin film press button structure improvement, by improvement of the present utility model, increases the reflectivity of elastic piece structure, is beneficial to the reflection extraneous light.
The purpose of this utility model is to be to provide a kind of thin film press button structure improvement, by improvement of the present utility model, reduces elastic piece structure thickness.
For achieving the above object, the utility model provides a kind of thin film press button structure improvement, its structure is made of metal clips, insulating barrier and the aluminium-vapour deposition layer that is formed at insulating barrier top, wherein, the aluminium-vapour deposition layer is the upper surface that is formed on insulating barrier in the evaporation mode continuously, to constitute an insulating barrier with aluminium-vapour deposition layer, the insulating barrier that again this is had the aluminium-vapour deposition layer covers the metal clips top continuously, is connected by adhesion layer between insulating barrier and the metal clips.
Description of drawings
Fig. 1 is a unit of the present utility model sectional drawing.
Fig. 2 is the use-case top view that makes of the present utility model.
The figure number explanation
100 film keys
10 metal clipss
11 base portions
20 adhesion layers
30 insulating barriers
40 aluminium-vapour deposition layers
Embodiment
For making the utility model content obtain to understand more specifically, now illustrate several preferred embodiments and cooperate icon to be described in detail as follows.In addition, except that this was described in detail, the utility model also can be performed among other embodiment widely.
Fig. 1 is the unit cross-section structure of thin film press button structure improvement of the present utility model.Film key 100 comprises: be the metal clips 10 of dome shape, it is made by stainless steel or other conductivity good metal material, is positioned on the base portion 11; It above metal clips 10 continuous insulating barrier 30, this insulating barrier 30 can cover a plurality of metal clipss of having arranged 10 simultaneously, form the conductive junction point array, the material of insulating barrier 30 can be polyethylene terephthalate (Polyethylene Terephthalate in this embodiment; PET) or other insulating plastics material, then form the adhesion layer 20 of about 0.015mm of thickness or not enough 0.015mm between metal clips 10 and the insulating barrier 30 by thin glue coating, fixing to form; Aluminium-vapour deposition layer 40 is the tops that are formed on insulating barrier 30 in the evaporation mode, in the utility model embodiment, with the material of aluminium as aluminium-vapour deposition layer 40.
The utility model adopts the mode of aluminium-vapour deposition layer 40 with evaporation is formed on the insulating barrier 30, constitute a ultrathin aluminium insulation film structure, and make its whole THICKNESS CONTROL between 0.020mm-0.025mm, the insulation film structure of comparing located by prior art is thinner, the aluminium-vapour deposition layer tack, the density that are deposited on the surface are better, simultaneously can reach grounding function, and cost is also lower.Because the characteristic of aluminium-vapour deposition layer material makes the aluminium-vapour deposition laminar surface have the height light reflective, with the reflection extraneous light.For example, under the environment of Light-Emitting Diode (LED) lamp, use film key 100, can promote whole reflecting effect.
Fig. 2 makes the top view of use-case for the utility model thin film press button structure improvement one, is made of the unit repeated arrangement of above-mentioned Fig. 1.By finding out among the figure, it is the continuous top that covers all metal clipss that surperficial evaporation has the insulating barrier of aluminium-vapour deposition layer.
Except that said structure, the aluminium-vapour deposition layer 40 that the utility model forms on insulating barrier 30 can also be the lines or the network structure of geometry formation, and this structure can reach the effect that prevents static, ground connection equally, and has reduced cost.，
Thin film press button structure improvement of the present utility model, utilize the evaporation processing procedure that aluminium is plated on the thin isolation layer to form electric action, replaced original single insulating layer or the mode that silver coating is starched on insulating barrier, this mode effectively reduces the integrally-built thickness of film key, has simplified processing procedure, has reduced production cost, improve the intensity on film key surface, prolonged useful life.Have more new effect compared to located by prior art.Range of application of the present utility model, not only limit in the embodiment previously described, other all conductive materials can be plated in the mode of evaporation on the thin isolation layer to form conduction, as long as it is identical or similar with the purpose of this utility model and the effect that can reach, or belong to distortion of the present utility model or improvement, all should belong to the scope that the utility model is contained.The utility model really meets the regulation of Patent Law, and filing an application in the whence in accordance with the law, expects early to grant a patent.
