Description
Technical field
The present invention relates to the application structure designing technique of macromolecular elastomer button, specifically a kind of waterproof patch type
Flexible keypad.
Background technology
Conductive rubber key industry is an industry being born in the eighties of last century 80-90 ages.For the non-standard monomer silicon of tradition
The silica gel push-button of the problem of glue button is not suitable for surface mount process, surface-adhered type is suggested, i.e., in silica gel push-button pedestal
Pin holder is added, by being molded a set of formation patch type silica gel push-button；However, on the one hand, in face of in high density, high integration
Application scenario can not accomplish gapless high-density applications demand due to being exposed to button edge when pin welds；Another party
In waterproof applications occasion, existing patch type silica gel push-button not yet well solves Structure Designing Problem, can only be by separately in face
Addition tarpaulin can be only achieved waterproof effect.Therefore, for existing patch type silica gel push-button the problem of, it is necessary to be pasted from improving
The angle of chip silicone elastomer button application structure, designs a kind of high density and the good patch type silicone elastomer of water resistance is pressed
Key.
Invention content
The mesh of the present invention is in view of the deficiencies of the prior art and provides a kind of waterproof patch type flexible keypad, this to press
Key have preferable good waterproof performance, simple in structure, manufacturing cost is cheap.
Realizing the technical solution of the object of the invention is：
A kind of waterproof patch type flexible keypad, including pedestal and button software, the button software include that button is convex
Body, elastic soft and conductive contact, the conical round bar shape of elastic soft, osculum inner edge and the key convex body of elastic soft connect
It connects, the big opening end of elastic soft is connected with base upper surface, and is opened up among pedestal corresponding with the big opening end of elastic soft
The through-hole of size, conductive contact are arranged in the lower face of key convex body, and unlike the prior art, the chassis outer side is equipped with
Waterproof soft-sided, waterproof soft-sided is interior to be equipped at least one watertight cavity.
The base bottom is equipped with the built-in leg protruded down, and built-in leg does not expose to chassis outer side, built-in leg
Lower face and periphery be welding surface, built-in leg periphery be equipped with welding gap.
The pedestal is equipped with leg link, and leg link is connect with the upper surface of built-in leg.
The leg link is encapsulated in chassis interior.
The top half of the built-in leg is encapsulated in chassis interior.
The built-in leg is at least two.
The multiple that the built-in leg total quantity is 2.
The built-in leg is symmetrical in button bottom surface sections.
The lower half portion of the built-in leg only exposed lower surface and side, other parts are encapsulated in pedestal.
Built-in leg vertically protrudes down in base bottom.
It is electrical between the built-in leg of realization if leg link is designed as open circuit between multiple built-in legs
Open circuit.
After this button is installed on the smooth product in surface, when the pressure that key convex body is pressed down, button
Air among elastic soft will be forced out, at this point, the waterproof soft-sided of button pedestal will be in nature relaxed state, i.e. waterproof is empty
Chamber size is constant；After the pressing force of key convex body is released, button elastic soft is up sprung back, the air among elastic soft
Pressure can become smaller, and the air in watertight cavity will be inhaled among elastic soft；Under pressure, the waterproof soft-sided of button pedestal
It will shrink inward, i.e., watertight cavity becomes smaller, and soft-sided will be adjacent on smooth product surface, prevents water from flowing into button to play
Internal effect.
This patch type flexible keypad, integrally solves the problems, such as the function of flexible keypad surface mount and waterproof, no
But it is suitable for surface mount application, and has the advantages that manufacturing cost is cheap, practicability is good；The lead coplanarity of the button is good,
It can be with the requirement of simple realization different key pin size, shape and quantity；In addition, gapless arrangement may be implemented in the button
It uses, is suitable for high density, the products application occasion of small size.
This button have preferable good waterproof performance, simple in structure, manufacturing cost is cheap.

Specific implementation mode
With reference to the accompanying drawings and examples to the content of present invention make further to elaboration, but be not to the present invention limit
It is fixed.
Embodiment：
Referring to Fig. 1-4, a kind of waterproof patch type flexible keypad, including pedestal 3 and button software, the button software
Including key convex body 1, elastic soft 2 and conductive contact 6,2 conical round bar shape of elastic soft, in the osculum of elastic soft 2
Edge is connect with key convex body 1, and the big opening end of elastic soft 2 is connected with 3 upper surface of pedestal, and is opened up among pedestal 3 and elasticity
The through-hole of the corresponding size of big opening end of software 2, conductive contact 6 are arranged in the lower face of key convex body 1,3 outside of the pedestal
Equipped with waterproof soft-sided 7, at least one watertight cavity 4 is equipped in waterproof soft-sided 7.
3 bottom of the pedestal is equipped with the built-in leg 5 protruded down, and built-in leg 5 does not expose to 3 outside of pedestal, built-in
The lower face and periphery of leg 5 are welding surface, and 5 periphery of built-in leg is equipped with the gap of welding.
The pedestal 3 is equipped with leg link 8, and leg link 8 connect with the upper surface of built-in leg 5, thus at
Simply leg 5 can be embedded in inside pedestal 3 in type technique, realize the built-in effect of leg 5.
The leg link 8 is encapsulated in inside pedestal 3.
The top half of the built-in leg 5 is encapsulated in inside pedestal 3 so that leg 5 formed with pedestal 3 it is integrated
, while the face of weld for being easy to implement leg 5 is exposed, and can simply control the coplanarity of button leg 5；
The built-in leg 5 is at least two.
The multiple that 5 total quantity of the built-in leg is 2.
The built-in leg 5 is symmetrical in button bottom surface, is balanced when being easy to implement button use.
The lower half portion of built-in leg 5 the exposed lower surfaces and side, built-in leg 5 is in 3 bottom of pedestal toward sagging
Straight protrusion, other parts are encapsulated in pedestal 3, to realize that lower face and the surrounding of control leg 5 are welding surface.
Between multiple built-in legs 5, if leg link 8 is designed as open circuit, the electricity between built-in leg 5 is realized
Gas is opened a way.
After this button is installed on the smooth product in surface, when the pressure that key convex body 1 is pressed down, button
Air among elastic soft 2 will be forced out, at this point, the waterproof soft-sided 7 of button pedestal 3 will be in nature relaxed state, i.e., it is anti-
4 size of water cavity is constant；After the pressing force of key convex body 1 is released, button elastic soft 2 is up sprung back, in elastic soft 2
Between air pressure can become smaller, the air in watertight cavity 4 will be inhaled among elastic soft 2；Under pressure, button pedestal
3 waterproof soft-sided 7 will be shunk inward, i.e., watertight cavity 4 becomes smaller, and waterproof soft-sided will be adjacent on smooth product surface, to
Play the role of preventing water from flowing into key inside.
