Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each embodiment of the present utility model is explained in detail。But, it will be understood by those skilled in the art that in each embodiment of this utility model, propose many ins and outs in order to make reader be more fully understood that the application。But, even without these ins and outs with based on the many variations of following embodiment and amendment, it is also possible to realize the application each claim technical scheme required for protection。

First embodiment of the present utility model relates to a kind of button, shown in Figure 2, including the cavity formed by shell 201, the switch 202 being located in cavity and inner surface and the just trigger mechanism 203 to the trigger unit 205 of switch 202 of being located at shell 201。Wherein, the position that connects of switch 202 forms shell fragment 206, at least part of shell 201 that stretches out of shell fragment 206 to form support portion 2061, support portion 2061 and external agency 204 be electrically connected and support portion 2061 for support with external agency 204。Shell 201 can relatively switch 202 and move to the direction of external agency 204, and when shell 201 is by pressed by external force, trigger mechanism 203 moves to trigger unit 205 and contacts trigger unit 205 so that switch 202 Guan Bi。

Wherein, switch 202 can be mechanical switch 202 or metal dome, it is also possible to is two unconnected wires。When switching 202 and being mechanical switch 202 or metal dome, trigger unit 205 physical contact of trigger mechanism 203 and switch 202。When switching 202 and being wire, it is possible to form the conductive plate of larger area in the end of two wires, trigger mechanism 203 then can include the contact of two electrical connections just conductive plate arranged。When trigger mechanism 203 contacts trigger unit 205, wire will be switched on, switch 202 Guan Bi。Obviously, switch 202 can also be other structures, and this has no effect on the realization of goal of the invention of the present utility model。

In the present embodiment, trigger mechanism 203 is protruding to the direction of trigger unit 205。Utilize projection can reduce shell 201 material, save cost, and prevent invalid contact。Meanwhile, trigger unit 205 is also protruding to the direction of trigger mechanism 203。This projection makes trigger unit 205 just to shell 201 boss, further increases contacting efficiency。

It addition, in the present embodiment, the bending part that support portion 2061 is bending structure and bending structure props up external agency 204。Utilize bending structure can strengthen the elasticity of support portion 2061。Meanwhile, the position that shell fragment 206 contacts with shell 201 extends and is formed guide portion 2062 along the direction of motion of shell 201, and guide portion 2062 is connected with support portion 2061。Utilize guide portion 2062 can guide the relative motion of shell 201, extend push button longevity。It is of course also possible to the support that is used for being made by the Kong Kai great of shell fragment 206 shell fragment 206 on shell 201 is more smooth and easy, its concrete implementation mode is not according to the restriction of paired technical solutions of the utility model。

In terms of existing technologies, embodiment of the present utility model is contacted with the trigger unit 205 on switch 202 by the trigger mechanism 203 on shell 201, forms the folding to switch 202 and controls。In the present embodiment, utilizing the support portion 2061 that shell fragment 206 is formed that key switch 202 is formed support is possible to prevent switch 202 to follow shell 201 and move together。Owing to switch 202 is arranged in cavity, therefore whole button becomes an entirety。When assembling, it is only necessary to shell fragment 206 is electrically connected with external agency 204, button assembly can be completed。Its assembling procedure is simple, it is possible to production cost is greatly lowered。

Second embodiment of the present utility model relates to a kind of button。Second embodiment is the improvement of the first embodiment, mainly thes improvement is that: in the second embodiment of the present utility model, and it is elastic surface that shell 201 forms the face at the place, position of trigger mechanism 203。When pressing shell 201, there is elasticity in elastic surface, it is possible to makes trigger mechanism 203 and trigger unit 205 come in contact better, and weakens the stress burden of shell fragment 206, extends button service life。

3rd embodiment of the present utility model relates to a kind of mobile terminal。Which is provided with the button that the respective embodiments described above are addressed。

In the present embodiment, external agency 204 is the circuit board of mobile terminal。The side leakage copper of circuit board forms pad, and support portion 2061 props up pad。Utilizing pad shell fragment 206 to be formed to support and be electrically connected, it is with low cost, and technique is simple simultaneously。

Specifically, this mobile terminal can be: notebook computer, mobile phone or panel computer etc.。

It will be understood by those skilled in the art that the respective embodiments described above are to realize specific embodiment of the utility model, and in actual applications, it is possible in the form and details it is done various change, without departing from spirit and scope of the present utility model。
