Description
Technical field
The utility model relates to button field, in particular a kind of key structure.
Background technology
Silica gel push-button is as the term suggests be exactly take silica gel as the made button product of raw material, silica gel push-button belongs to a product category of silica gel product, and silica gel push-button has excellent thermal endurance, cold resistance, environment resistant, the feature such as electric insulating quality, fatigue durability.
Silica gel push-button is often used in the middle of electronic calculator, remote control system, telephone set, radiophone, computor-keyboard, learning machine button, scrambler button, digital product button.
Silica gel push-button comprises single-point silica gel push-button, remote controller silica gel push-button, conducting silica gel key, mobile phone silica gel push-button, touches silica gel push-button, translucent silica gel button, keyboard, scrambler button, vehicle-mounted button, film key, radium carving button, reset key, home button, pc button, learning machine button, pos machine button, scrambler button, digital product button, p+r button etc.
The silica gel push-button used in prior art, silica gel push-button must be arranged on product and could use, and as shown in Figure 1, the press-key structure of prior art comprises the silica gel push-button frame mode of prior art; Silica gel push-button 1, mounting panel 2; Key circuit PCBA 3 and contact switch 4; Moving up and down of button is realized when pressing silica gel push-button in prior art, as shown in Figure 2 by the distortion bottom button.
PCBA is the abbreviation of English Printed Circuit Board+Assembly, that is PCB hollow plate part on SMT, then through the whole processing procedure of DIP plug-in unit, is called for short PCBA.
The silica gel push-button of prior art in use there will be button edge abrasion, button is mounted the problem that board is lived, gap between button and mounting panel can accumulate dust, as shown in Figure 3.Because the silica gel push-button structure of prior art be by silica gel push-button below deformation realize moving up and down, in the process pressed, the first half of button wants mass motion, so the structures shape of silica gel push-button will have certain gap between mounting panel and button, not so former button cannot resilience; Can produce friction with mounting panel in the process of pressing movement can cause the edge 12 of button to wear and tear; If firmly 11 parts above button just may be blocked by malposition that is excessive or that press when pressing, causing cannot resilience.And 13 easily accumulate dust around button of the prior art.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of key structure.The utility model will solve edge abrasion that silica gel push-button in use may occur, is stuck, can accumulate the problem of dust around button.
The technical solution of the utility model is as follows:
A kind of key structure, wherein, comprise: be arranged on the contact switch in PCBA board, what be arranged on contact switch upper end can contact the key contact body connected with described contact switch, and is connected the key main body moved up and down for supporting described key contact body with described key contact body;
Be provided with the chamber for installing described contact in described key main body, described contact is arranged on can the chamber upper wall of deformation, drives the key contact body of chamber nexine to move up and down when pressing by the deformation on key main body top.
Described key structure, wherein, it also comprises the mounting panel for installing described key main body.
Described key structure, wherein, described key main body arranged outside has the L tee section side for being closely connected with mounting panel.
Described key structure, wherein, described L tee section side is pasted with described mounting panel and is connected.
Key contact body and key main body are made of one setting.
Key structure provided by the utility model, the utility model adopts double-deck button design, drives the button of nexine to move up and down when pressing by the deformation on top.And the skin contacted with mounting panel does not move, so the skin of button can realize seamless contact with mounting panel, solve the edge abrasion of prior art structure button at this point, be stuck, can accumulate around button the problem of dust.And substantially prolongs the useful life of button.

Embodiment
The utility model provides a kind of key structure, for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes the utility model referring to accompanying drawing examples.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of key structure that the utility model embodiment provides, as shown in Figure 4, comprise: be arranged on the contact switch 24 in PCBA board 23, what be arranged on contact switch 24 upper end can contact with described contact switch 24 the key contact body 211 connected, and the key main body 21 moved up and down for supporting described key contact body 211 is connected with described key contact body 211, also comprise the mounting panel 22 for installing described key main body 21.Key contact body 211 and the key main body 21 of the present embodiment are made of one setting.
The chamber for installing described contact 211 is provided with in described key main body 21, described contact 211 is arranged on can the chamber upper wall of deformation, as shown in Figure 5, the key contact body 211 of chamber nexine is driven to move up and down by the deformation on key main body 21 top when pressing.
Described key structure, wherein, described key main body 21 arranged outside has the L tee section side for being closely connected with mounting panel 22.Described L tee section side is pasted with described mounting panel 22 and is connected, and can not accumulate dust around such key main body.
Key structure provided by the utility model, adopt double-deck button design, the button of nexine is driven to move up and down by the deformation on top when pressing, and the skin contacted with mounting panel 22 does not move, so the skin of button can realize seamless contact with mounting panel 22, solve the edge abrasion of prior art structure button at this point, be stuck, can accumulate around button the problem of dust, and substantially prolongs the useful life of button.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection range that all should belong to the utility model claims.
