Description
Technical field
The invention belongs to membrane switch technology fields, are related to a kind of color gradual changing film switch.
Background technique
Thin film switch is an operating system for integrating keypress function, indicator elment, instrument panel.By panel, on
Circuit, separation layer, four part of lower circuit composition.Thin film switch is pressed, the contact of upper circuit deforms downwards, the pole plate with lower circuit
Contact conducting, after finger unclamps, upper circuit contact rebound is returned, and circuit disconnects, and a signal is triggered in circuit.Thin film switch structure
Rigorously, good appearance, good airproof performance.With moisture proof, the features such as long service life.It is widely used in telecommunications, electronic, horological
The instrument of amount, Industry Control, Medical Devices, auto industry, intelligent toy, the fields such as household electrical appliance.
Thin film switch can be improved the feel, technology sense and class sense of electronic and electrical equipment, and film in the prior art is opened
It closes, is all the plate that got an electric shock by press contacts under reed, so that conducting is realized, however, it has following defects that 1, thin film switch row
Journey is smaller, is typically all by prompt tone while to trigger what light source was prompted whether conducting, which increase in thin film switch
Portion's structure improves the cost of thin film switch, decline；2, thin film switch in use for some time, lead by reed deformation
The lower pressure for causing conducting to need increases, and then failure；3, when the reed of thin film switch pushes, lower pressure cannot be mentioned well
Show, to often will appear firmly excessive, feel is poor, or even the case where damage thin film switch by pressure.
Summary of the invention
In view of the above problems existing in the prior art, the purpose of the present invention is to provide a kind of color gradual changing film switches, originally
The technical problems to be solved by the invention are to prompt lower pressure by gradient color how in lower making leaf spring.
Object of the invention can be realized by the following technical scheme: a kind of color gradual changing film switch, which is characterized in that this
Thin film switch includes panel, mounting base and the reed between panel and mounting base, the reed include convex forced section,
The support portion of vertical panel and the conducting portion between forced section and support portion, the conducting portion are stretched out to reed inside, institute
The pilot hole that vertical panel is offered in mounting base is stated, the light-transmitting plate being equipped on the outside of reed in the mounting base is described
There are in light-transmitting plate several to be uniformly distributed and in the radial through-hole to scatter on the outside of reed, there is oil storage in the mounting base
Slot, the pilot hole are communicated by oil storage tank with all through-holes, and a guide post, the guide post are inserted in the pilot hole
Upper end be fixedly linked with the forced section；The mixture of silicone oil and ink is filled in the oil storage tank and pilot hole；It is described
The lower end of light-transmitting plate has the strip-shaped light source being located in mounting base.
In a kind of above-mentioned color gradual changing film switch, several pressurized holes, the pressurization are offered in the mounting base
The lower ending opening in hole is communicated with oil storage tank, is inserted with a guide rod in each pressurized hole, and the guide rod is movably connected in pair
In the pressurized hole answered, the contact chip that the upper end of all guide rods is located at below conducting portion with one is fixedly linked, the increasing
Press the lower end in hole in horn-like, the lower end of the pressurized hole is fixedly connected with the Thin Elastic for covering the lower ending opening of pressurized hole
Film.
In a kind of above-mentioned color gradual changing film switch, several indicating lights are provided between the panel and light-transmitting plate,
The indicating light is powered under thin film switch on state.
In a kind of above-mentioned color gradual changing film switch, inclined upward from the light-transmitting plate to the outside of reed, it is described
Inclination angle between tabula rasa and guide post is between 80~85 °.
Principle is as follows: by the forced section of making leaf spring, guide post being driven to move down in pilot hole, filled out in oil storage tank and pilot hole
For the mixture of the silicone oil of note and ink along oil storage tank to logical pore diffusion, it is bigger that guide post pushes displacement, and thing liquid is mixed in through-hole
The ulking thickness of body is bigger, under the illumination of strip-shaped light source, the color fringe of visual strip on panel, and with the pushing of reed
The variation of power and change colour, until thin film switch be connected, triggering indicating light connect, under the accessible illumination of indicating light,
Intensity covers strip-shaped light source, and entire panel is shown as more limpid state, indicates thin film switch conducting.
When reed presses to a certain position, the mixture pressure of the silicone oil and ink filled in oil storage tank and pilot hole increases
Greatly, elastic film is driven, is moved up to squeeze guide rod, the conducting portion of reed is enable to contact with contact chip, the structure setting
Thin film switch presses to pressure under the limit of triggering and pushes displacement, so that thin film switch be prevented to be damaged by weight, while also mentioning
High thin film switch pushes sensitivity and operating handle.
For light-transmitting plate to the inclined upward in the outside of reed, the inclination angle between light-transmitting plate and guide post is storage between 80~85 °
During the mixture of the silicone oil and ink filled in oil groove and pilot hole is increasing in through-hole, forms one and constantly fill out
The process of through-hole is filled, then, when pressing making leaf spring, forms the aperture to external diffusion on the outside of reed, it is changed same in color
When, further operator is prompted.
In a kind of above-mentioned color gradual changing film switch, the silicone oil filled in the oil storage tank and pilot hole and ink it is mixed
The ratio of conjunction object, silicone oil and ink is three to one.
Ink and silicone oil mixing, color is light, and condensation point is low, is not easy to evaporate, and mobility is strong, is not adhere to be made into peace
Fill the plastic material of seat.
Compared with prior art, the invention has the following advantages that
1, when reed presses to a certain position, the mixture pressure of the silicone oil and ink filled in oil storage tank and pilot hole
Increase, drives elastic film, moved up to squeeze guide rod, the conducting portion of reed is enable to contact with contact chip, the structure setting
Thin film switch presses to pressure under the limit of triggering and pushes displacement, thus prevent the thin film switch to be damaged by weight, while
It improves thin film switch and pushes sensitivity and operating handle；
2, to the inclined upward in the outside of reed, inclination angle between light-transmitting plate and guide post is between 80~85 ° light-transmitting plate,
During the mixture of the silicone oil and ink filled in oil storage tank and pilot hole is increasing in through-hole, one is formed constantly
The process of through-hole is filled, then, when pressing making leaf spring, forms the aperture to external diffusion on the outside of reed, it is changed in color
Meanwhile further operator is prompted.
