Description
Technical field
This utility model relates to the application structure designing technique of macromolecular elastomer button, a kind of waterproof SMD flexible keypad.
Background technology
Conductive rubber key industry is the industry being born in the eighties of last century 80-90 age.The problem not being suitable for surface mount process for traditional non-standard monomer silica gel push-button, the silica gel push-button of surface-adhered type is suggested, and i.e. adds pin support at silica gel push-button base, by molding the SMD silica gel push-button of a set of formation；But, on the one hand, in the face of in high density, the application scenario of high integration, owing to being exposed to button edge when pin welds, it is impossible to accomplish gapless high-density applications demand；On the other hand in waterproof applications occasion, existing SMD silica gel push-button solves Structure Designing Problem the most well, can only can be only achieved waterproof effect by adding tarpaulin separately.Therefore, for the problem of existing SMD silica gel push-button, necessary from improving the angle of SMD silicone elastomer button application structure, design a kind of high density and the good SMD silicone elastomer button of water resistance.
Utility model content
Mesh of the present utility model is to provide a kind of waterproof SMD flexible keypad for the deficiencies in the prior art, and this button has preferable good waterproof performance, simple in construction, cheap for manufacturing cost.
The technical scheme realizing this utility model purpose is:
A kind of waterproof SMD flexible keypad, including base and button software, described button software includes key convex body, elastic soft and conductive contact, the conical round bar shape of elastic soft, the osculum inner edge of elastic soft is connected with key convex body, the big opening end of elastic soft is connected with base upper surface, and in the middle of base, offer the through hole of size corresponding with the big opening end of elastic soft, conductive contact is arranged on the lower surface of key convex body, unlike the prior art, described chassis outer side is provided with waterproof soft-sided, is provided with at least one watertight cavity in waterproof soft-sided.
Described base bottom is provided with the built-in leg down protruded, and built-in leg does not expose to chassis outer side, and the lower surface of built-in leg and periphery are solder side, and built-in leg periphery is provided with the space of welding.
Described base is provided with leg link, and leg link is connected with the upper surface of built-in leg.
Described leg link is encapsulated in chassis interior.
The top half of described built-in leg is encapsulated in chassis interior.
Described built-in leg is at least 2.
Described built-in leg total quantity is the multiple of 2.
Described built-in leg is symmetrical in button bottom surface sections.
Described built-in leg only exposes the latter half of lower surface and side, and other parts are encapsulated in base.
Built-in leg the most vertically protrudes at base bottom.
Between multiple built-in legs, if leg link is designed as open circuit, then realize the electrical open between built-in leg.
After this button is installed on ganoid product, when the pressure that key convex body is down pressed, the air in the middle of button elastic soft will be forced out, and now, the waterproof soft-sided of button base will be in nature relaxed state, i.e. watertight cavity size is constant；When, after being released by pressure of key convex body, the up resilience of button elastic soft, the air pressure in the middle of elastic soft can diminish, and the air in watertight cavity will be inhaled in the middle of elastic soft；Under pressure, the waterproof soft-sided of button base will be shunk inward, i.e. watertight cavity diminishes, and soft-sided will be adjacent on smooth product surface, thus play the effect preventing water from flowing into key inside.
This SMD flexible keypad, integrally solves flexible keypad surface mount and waterproof function problem, is not only applicable to surface mount application, has again advantage cheap for manufacturing cost, that practicality is good；The lead coplanarity of this button is good, can be with simple realization different key pin size, shape and the requirement of quantity；Use additionally, this button can realize gapless arrangement, it is adaptable to high density, the products application occasion of small size.
This button has preferable good waterproof performance, simple in construction, cheap for manufacturing cost.

Detailed description of the invention
With embodiment this utility model content made below in conjunction with the accompanying drawings further to elaboration, but be not to restriction of the present utility model.
Embodiment:
See Fig. 1-4, a kind of waterproof SMD flexible keypad, including base 3 and button software, described button software includes key convex body 1, elastic soft 2 and conductive contact 6, the conical round bar shape of elastic soft 2, the osculum inner edge of elastic soft 2 is connected with key convex body 1, the big opening end of elastic soft 2 is connected with base 3 upper surface, and in the middle of base 3, offer the through hole of size corresponding with the big opening end of elastic soft 2, conductive contact 6 is arranged on the lower surface of key convex body 1, waterproof soft-sided 7 it is provided with outside described base 3, at least one watertight cavity 4 it is provided with in waterproof soft-sided 7.
Being provided with the built-in leg 5 down protruded bottom described base 3, built-in leg 5 does not expose to outside base 3, and the lower surface of built-in leg 5 and periphery are solder side, and built-in leg 5 periphery is provided with the space of welding.
Described base 3 is provided with leg link 8, and leg link 8 is connected with the upper surface of built-in leg 5, thus can be embedded in inside base 3 by leg 5 simply in moulding process, it is achieved the built-in effect of leg 5.
It is internal that described leg link 8 is encapsulated in base 3.
It is internal that the top half of described built-in leg 5 is encapsulated in base 3, so that leg 5 is formed integrated with base 3, simultaneously facilitates and realizes the face of weld of leg 5 and expose, it is possible to controls the coplanarity of button leg 5 simply well；
Described built-in leg 5 is at least 2.
Described built-in leg 5 total quantity is the multiple of 2.
Described built-in leg 5 is symmetrical in button bottom surface, it is simple to realize balance when button uses.
