Abstract

The utility model discloses a metallic elastic-strip key, which is used for the keyboard of an electronic product and is arranged between the silicon rubber base key and the printed circuit board of the keyboard. The metallic elastic-strip key comprises a circular-arch-shaped elastic strip body and an upwards convex contact which extends upwards and convexly from the center of the elastic strip body. A plurality of downwards concave contacts which take a conducting effect are formed around the upwards convex contact in a concaving way. Since the metallic elastic-strip key is provided with the upwards convex contact and the downwards concave contacts, when a user does not accurately press the center of the silicon rubber base key or the position of the silicon rubber base key is deviated, the finger of the user can be in full contact with the upwards convex contact, the central part of the metallic elastic-strip key is deformed normally, downwards, concavely and elastically, the downwards concave contacts are ensured to be in good contact with a conducting terminal on the printed circuit board, the clicking accuracy is improved and the clicking hand feeling is always kept to be good.

Description

The metal clips button
Technical field
The utility model relates to the electronic product accessory, relates in particular to a kind of metal clips button that is used for the button module of electronic product.
Background technology
In the modernized information-intensive society of information communication system high development, electronic installation is widely used in the every field, for example electronic products such as mobile phone, MP3 and PDA are widely used in the daily life, people can carry out information exchange whenever and wherever possible by mobile phone, experience is shared and communication, MP3 then can be people and brings amusement, loosens mood.Under the popularizing day by day of electronic equipment, technology reaches its maturity, external form is changeable day by day and volume dwindles day by day situation, the operation keyboard that how to improve electronic product can be operated the user more easily, also becomes one of important topic of current design.
With the mobile phone is example, general cell phone keyboard as depicted in figs. 1 and 2, it comprises: go up enclosure 1, enclosure 2 and place button module in the upper and lower enclosure down.Described button module comprises: the printed circuit board (PCB) 3 that is formed with conducting terminal 3a; Be arranged on the above-mentioned printed circuit board (PCB) 3 and be used for being connected or a plurality of metal clips buttons 4 of conducting with described conducting terminal 3a selectivity; Be positioned on the above-mentioned printed circuit board (PCB) 3, be used to be provided with the substrate 5 of metal clips button 4; On substrate 5, be used for fixing the adhesive tape 6 of metal clips button 4; Be positioned at the top of metal clips button 4, can make the light guide plate 7 of the divergence of beam that indicator light sends; And be arranged on enclosure 1, and metal clips button 4 is exerted pressure, make it produce the silica gel base button 9 of deformation.Like this, when the user pressed the operation that silica gel base button 9 decontrols again, shown in Fig. 3 a, the central portion of metal clips button 4 produced recessed elastic deformation, thereby contact also conducting with conducting terminal 3a.
Yet, for above-mentioned existing cell phone keyboard, as shown in Figure 2, when the user when direction of arrow a presses the centre portion of silica gel base button 9 exactly, it can be exerted pressure to the centre portion of metal clips button 4 along direction of arrow a1, thereby shown in Fig. 3 a, makes the dome-shaped central portion produce elastic deformation downwards, well contacting, and guarantee good click feel with conducting terminal 3a; If but owing to the user does not note, press the peripheral position of arriving the centre portion that breaks away from silica gel base button 9 along direction of arrow a or c, adverse consequences shown in Fig. 3 b then can appear, because the central portion of metal clips button 4 is dome-shaped, to produce than large elastic deformation by the position of b1 directional pressure effect, do not have a reverse side of pressure effect then to produce less elastic deformation.Therefore, will be when the central portion of metal clips button 4 produces elastic deformation to lopsidedness, the misoperation that can not contact with conducting terminal 3a might appear, and must press silica gel base button 9 this moment once more, bothers very much.Even contact with conducting terminal 3a smoothly, also reduced the click feel significantly.
Therefore, be badly in need of a kind of click feel better and the metal clips button that can avoid misoperation to address the aforementioned drawbacks.
The utility model content
The purpose of this utility model is to provide a kind of and clicks feel better and can avoid the metal clips button of misoperation.
The utility model provides a kind of metal clips button for achieving the above object, the keyboard that is used for electronic product, described metal clips button is arranged between the silica gel base button and printed circuit board (PCB) of described keyboard, described metal clips button comprises the spring plate that is dome-shaped and the epirelief contact that upwards protrudes out from the center of described spring plate, the peripheral recesses of described epirelief contact and form the recessed contact that several play electric action.
The utility model is compared with prior art, because the utility model metal clips button is provided with epirelief contact and recessed contact, fail accurately by it also can fully contact and make the recessed elastic deformation of the normal generation of central part of metal clips button with the epirelief contact when off normal appears in silica gel base button centre or silica gel base button self the user, thereby guarantee that recessed contact well contacts with conducting terminal on the printed circuit board (PCB), improve the click accuracy, and remained good click feel.
Preferably, described epirelief contact is greater than each described recessed contact.
Preferably, some described recessed contacts be distributed in equably described epirelief contact around.
Preferably, rounded, ellipse in described epirelief contact or polygon.
Preferably, rounded, ellipse in described epirelief contact or polygon.
Preferably, the thickness of described spring plate is 0.055mm.
