Abstract
The utility model discloses a membrane switch of sense of touch design, from table to lining include panel layer, face glue film in proper order, go up the circuit layer, isolation layer, circuit layer and primer layer down, upward be equipped with an at least metal shrapnel on the circuit layer, button position on the corresponding panel layer of each metal shrapnel, the panel layer is equipped with the fluting in each button position department, and each fluting cooperates a silica gel key respectively, silica gel key and fluting sealing connection, and silica gel key and metal shrapnel are corresponding. The utility model discloses membrane switch adopts silica gel key's design, has combined membrane switch and silica gel key's advantage, and the modern design makes this membrane switch's button have the antiskid, has the damping, has the premium properties of sense of touch, and feeling of touch button is better.
Description
Technical field
The utility model relates to a kind of thin film switch, refers to the thin film switch of a kind of sense of touch design that a kind of and thin film switch and silica gel push-button advantage are integrated especially.
Background technology
Thin film switch is the operating system integrating keypress function, indicator elment, instrument panel, there is long, the resistance to bending of good looking appearance, life-span, sealing be strong, waterproof, oil-stain-preventing, shockproof, resistance toly to fall, advantage that the little ordinary tap such as ultra-thin, lightweight of volume is incomparable.Be widely used in the instrument of telecommunications, electronic measurements, Industry Control, Medical Devices, auto industry, intelligent toy, household electrical appliance, instrument etc. field.Along with the purposes of thin film switch is more and more extensive, the upgrading of industry and the requirement of consumer increase, and improve higher requirement and new technological challenge to thin film switch product.The thin film switch produced in the market is various informative: although plane is without sense of touch type long service life, do not have sense of touch; Although film convex surface sense of touch type has good sense of touch, useful life is short; Although chimb frame is specious without sense of touch type, third dimension is strong, without sense of touch type etc.
Common thin film switch as shown in Figure 1, panel layer 1, face glue-line 2, upper circuit layer 3, separator 4, lower circuit layer 5 and primer layer 6 is drawn together to inner being provided with successively from table, upper circuit layer 3 is provided with metal clips, and namely this metal clips is the position of the switch on corresponding surface flaggy 1.In use, when pressing with the position of the switch that finger aligning surface flaggy 1 is provided with, metal clips is pressed, the pad the same circuit board in shell fragment center being located immediately at shell fragment central lower contacts, thus electrical connection is set up between the pad of upper circuit layer 3 and lower circuit layer 4 liang of printed circuit board (PCB)s, reasonably combined by both, realizes the effective conducting after assembling.
The position of the switch of thin film switch needs finger aligning surface flaggy 1 when operating of said structure is pressed, due to the level and smooth undamped of panel layer 1, during pressing, finger easily slides, cause pressing feel bad, in addition, accurately cannot aim at the shortcoming of the position of the switch time film face-plate of this structure exists finger presses, thus the shortcoming such as easily cause misoperation, button ineffective simultaneously, need larger power to operate also easily to cause that switch internal circuit damages, afunction for a long time.
Utility model content
The purpose of this utility model is that improving existing thin film switch touch key-press easily slides, the problem that sense of touch is poor, and the thin film switch of the sense of touch design providing a kind of sense of touch good.
Another object of the present utility model is to provide a kind of thin film switch increasing the sense of touch design of key contacts sensitivity.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of thin film switch of sense of touch design, panel layer, face glue-line, upper circuit layer, separator, lower circuit layer and primer layer is comprised successively to inner from table, upper circuit layer is provided with at least one metal clips, key position on each metal clips corresponding surface flaggy, described panel layer is provided with fluting in each key position place, each fluting coordinates a silica gel push-button respectively, and silica gel push-button and fluting are tightly connected, and silica gel push-button is corresponding with metal clips.
The center position of the corresponding metal clips in the back side of described silica gel push-button is provided with a boss.
Described silica gel push-button is shaped in the fluting of panel layer.
After adopting said structure, the thin film switch of the utility model sense of touch design increases the design of silica gel push-button, combine the advantage of thin film switch and silica gel push-button, novel in design, make the button of this thin film switch have premium properties that is anti-skidding, that have damping, have sense of touch, make the feel of this thin film switch touch key-press better.Silica gel push-button and panel layer adopt Seal Design, waterproof, dust-proof, grease proofing, anti-soda acid, can use in any rugged environment, and can carry out disinfection and clean in water; In addition, the boss that silica gel push-button back is arranged, can increase the sensitivity of key contacts.

Fig. 2 is structural representation of the present utility model;
Fig. 3 is the cutaway view of the utility model silica gel push-button.
Embodiment
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
As shown in Figures 2 and 3, the utility model is the thin film switch of a kind of sense of touch design, this thin film switch is by showing to comprise panel layer 1, face glue-line 2, upper circuit layer 3, separator 4, lower circuit layer 5 and primer layer 6 successively to inner, panel layer 1 is provided with the key position of function or switch, each function or switch key position are respectively to slot 11, each fluting 11 coordinates a silica gel push-button 7 respectively, silica gel push-button 7 is tightly connected with fluting 11, in the present embodiment, the two ends of this silica gel push-button 7 form a flange 71 and are directly shaped in fluting 11 back side of panel layer 1.On upper circuit layer 3, the position of corresponding each silica gel push-button 7 is respectively equipped with a metal clips 31 coordinated with silica gel push-button 7 activity, and one end that silica gel push-button 7 coordinates with metal clips 31 is provided with a boss 72, this boss 72 can ensure that this silica gel push-button 7 is more effective with the contact of metal clips 31, thus improves the sensitivity of silica gel push-button 7.
When using the thin film switch of this sense of touch design, the button design due to panel layer 1 is silica gel push-button 7, and silica gel push-button 7 has characteristic that is anti-skidding, that have damping, have sense of touch, therefore can improve the shortcoming that switch key sense of touch now can be had poor.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
