Description
Technical field
The utility model relates to a kind of seven key thin film switches, belong to application of electronic technology field.
Background technique
Thin film switch is also known as soft-touch type keyboard, and the integral seal structure being composed using planar multilayer is to open key
Pass, panel, label, the light, mechanical, electrical integrated a kind of new electronic component of collection that symbol is shown and liner plate is sealed,
It is the change of electronic product surface structure, it may replace the key of conventional discrete element, more reliably execute appointing for operating system
Business.It is widely used in telecommunications, electronic instrument, the multiple fields such as household electrical appliance.
It is not general, common switch at present that outer dimension, number of keys, the structure and function of thin film switch, which define etc.,
It is exactly to have a single function that structure is complicated, and leakproofness is poor, physical life is short.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art, provide it is a kind of of a tightly knit structure, outside
The thin film switch for the features such as shape is beautiful, good airproof performance, and has moisture proof, long service life.
In order to solve the above technical problems, the utility model provides a kind of seven key thin film switches, successively include from top to bottom
Face mask layer, upper separation layer, upper circuit layer, lower separation layer, lower circuit layer and gum layer；Between each layer through thermostabilization, anti-shrinkage at
It is adhesively fixed after reason；The upper circuit layer be equipped with seven flexibility function contacts, the lower circuit layer be equipped with switching circuit and with
Upper circuit layer flexibility function contact position corresponding position is equipped with pole；When pressing face mask layer respective keys mark, the upper circuit
The flexibility function contact of layer deforms downwards, contacts conducting with the pole of lower circuit layer；After finger unclamps, the flexibility of upper circuit layer
Contact rebound is returned, and circuit disconnects.
The technical solution that the utility model further limits is: the face mask layer, upper and lower separation layer, upper and lower circuit layer are adopted
It is made of fexible film.
Further, the upper and lower circuit layer uses carrier of the polyester film as switching circuit figure.
Further, the lower circuit layer further includes the lead-out wire connecting with the switching circuit；The switching circuit
Figure, online and lead-out wire are all made of cured conductive coating paint printing under low resistance, cryogenic conditions and are made.
The beneficial effects of the utility model are: this thin film switch is a kind of to show key switch, panel, label, symbol
And the Novel electronic devices that liner plate is sealed, it may replace the key of conventional discrete element, more reliably execute operation system
The task of system.This thin film switch have good waterproof and dustproof characteristic, it is stable and reliable for performance, light-weight, small in size, flexible,
The advantages that service life is long, dress connection is convenient, beautiful and generous.It can be widely applied to the fields such as telecommunications, electronic instrument.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model embodiment 1.
Fig. 2 is the structural exploded view of the utility model embodiment 1.
Fig. 3 is the circuit and lead-out wire schematic diagram of the utility model embodiment 1.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
Embodiment 1
A kind of seven keys thin film switch provided in this embodiment is collection keypress function, a designated symbol, instrument panel one
One operating system of body.It is as shown in Figs. 1-3: from top to bottom successively include face mask layer 1, upper separation layer 2, upper circuit layer 3, under every
Absciss layer 4, lower circuit layer 5 and gum layer 6；It handles, is bonded through thermostabilization, anti-shrinkage processing and adhesion between each layer.It is described
Upper circuit layer is equipped with seven flexibility function contacts, and the lower circuit layer is equipped with switching circuit and touches with upper circuit layer flexibility function
Point position corresponding position is equipped with pole；When pressing face mask layer respective keys mark, the flexibility function contact of the upper circuit layer to
Lower deformation contacts conducting with the pole of lower circuit layer；After finger unclamps, the flexible contacts rebound of upper circuit layer is returned, circuit
It disconnects, a signal is triggered in circuit, realizes feature operation task.
Face mask layer, separation layer, the circuit layer of the thin film switch are all made of various fexible films of different nature.It is soft
The circuit layer of property thin film switch, is all made of carrier of the good polyester film PET of electric property as switching circuit figure, this layer
Also feel elastic slice, upper and lower circuit are dispensed.By the influence of the had property of polyester film, so that the thin film switch is with good
Insulating properties, heat resistance, fold resistance and higher resilience.The figure of switching circuit, the online and its lead-out wire including switch are equal
Using low resistance, cured conductive coating paint prints under cryogenic conditions.Therefore, the composition of entire thin film switch has one
Fixed flexibility is not only suitable for using on plane body, moreover it is possible to cooperate with curved body.Fexible film switchs lead-out wire and switch body
Be in itself it is integrated, make group's switch it is online when, come together in certain of film, and the position specified by design
Set and extend outwardly with the line-spacing of standard, as it is soft, can any curved, sealing extraction wire and complete machine back-end circuit
It is connected.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
