It the utility model is related to electronic switching technology field, more particularly, to a kind of thin film switch structure-improved, include panel, upper circuit, separation layer, lower circuit, the lower circuit is provided with circuit, the exit of circuit is connected using terminal, upper circuit is provided with firing point, the circuit of the lower circuit of the corresponding conducting of firing point.The utility model designs circuit on lower circuit, and upper circuit only sets firing point, during assembling, simply individual layer riveting terminal, is to be contacted between face and face between terminal and circuit, conducting impedance is greatly reduced, stability strengthens, and the life-span can reach more than 35 years, and oxidative phenomena will not occur easily.
Description
Technical field
Electronic switching technology field is the utility model is related to, more particularly, to membrane switch technology field.
Background technology
Thin film switch by with a kind of multilayer planar type that certain elastic conductive material and insulation material layer form by
Key switch.Due to its good appearance, the characteristic such as in light weight, cost is low, it is widely used in all trades and professions, such as intelligent electronic instrument
In the various products such as device, Medical Instruments, Digit Control Machine Tool, communication apparatus, office appliance, household electrical appliances, computor-keyboard.The knot of thin film switch
Structure is mainly made up of panel, upper circuit, separation layer, the part of lower circuit four, is isolated between upper circuit and lower circuit by separation layer,
Upper circuit and lower circuit have circuit.When panel is not pressed, separation layer plays isolation to the circuit of upper circuit and lower circuit and made
With when panel is pressed, the circuit of upper circuit is pressed and overlapped with the circuit of lower circuit in the lump, makes line conduction, conducting
Afterwards circuit by output lead to external connection instrument with signal, realize its corresponding function.However, the film of said structure is opened
Close because there is circuit up and down, service outlet will be connected using terminal, circuit conducting surface inside the interlayer of upper and lower circuit,
Terminal rivets inwards outside, the contact area very little of terminal and the inside wire, is easily loosened again in operating process, so makes production
The conducting impedance increase of product is many and unstable, because being point contact between face, time more long easier oxidation, finally
Product loses function.
The content of the invention
The purpose of this utility model is to provide a kind of thin film switch structure-improved, and conducting impedance is greatly reduced, stability
Enhancing, oxidative phenomena will not occur easily.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of thin film switch structure-improved, includes panel, upper circuit, separation layer, lower circuit, and the lower circuit is provided with line
Road, the exit of circuit are connected using terminal, and upper circuit is provided with firing point, the circuit of the lower circuit of the corresponding conducting of firing point.
The utility model designs circuit on lower circuit, and upper circuit only sets firing point, and during assembling, simply individual layer rivets
Terminal, contacted between face and face between terminal and circuit, conducting impedance is greatly reduced, and stability enhancing, the life-span can reach
More than 3-5, oxidative phenomena will not occur easily.
Brief description of the drawings：
Accompanying drawing 1 is the utility model embodiment structural representation；
Accompanying drawing 2 is the lower electrical block diagram of Fig. 1 embodiments；
Accompanying drawing 3 is the upper electrical block diagram of Fig. 1 embodiments.
Embodiment：
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Refering to shown in Fig. 1,2,3, the utility model includes panel 1, upper circuit about a kind of thin film switch structure-improved
2nd, separation layer 3, lower circuit 4.The lower circuit 4 is provided with circuit 41, by printing electrically conductive ink on nonconducting film surface layer
（Electric conductivity silver paste or carbon slurry）Formed with non-conductive property dielectric ink, the exit of circuit 41 is connected using terminal, and upper circuit 2 is provided with
Firing point 21, the circuit 41 of the lower circuit 4 of the corresponding conducting of firing point 21.When panel 1 is pressed, the firing point 21 of upper circuit is in the lump
Be pressed and turn on the circuit 41 of lower circuit 4, after conducting circuit by output lead to external connection instrument with signal, realize it
Corresponding function.
The utility model is simple in construction, easily makes and assembles.By circuit design on lower circuit 4, and upper circuit 2 only sets and led
Logical point, during assembling, simply individual layer riveting terminal, is contacted between face and face between terminal and circuit, and conducting impedance is greatly reduced,
Stability strengthens, and the life-span can reach more than 3-5, oxidative phenomena will not occur easily.
The utility model is elaborated above in association with embodiment, is only to illustrate technical concept of the present utility model
And feature, can not be with this its object is to allow person skilled in the art to understand content of the present utility model and be carried out
Restriction the scope of protection of the utility model, therefore all equivalent change or modifications done according to the utility model Spirit Essence, all should
Cover in the scope of protection of the utility model.
