Utility model content

The purpose of this utility model is to provide a kind of electronic product improving button diastema, in order to reduce manufacturing cost and to improve button use feel.

For solving above-mentioned technical problem, embodiment of the present utility model provides a kind of electronic equipment, including a housing, the button that is arranged on housing, and with button with the use of flexible PCB, position corresponding with the conductive base of described button on described flexible PCB is provided with metal dome, being provided with elastic component between described button and described flexible PCB, described elastic component is distributed in around described metal dome.

In terms of existing technologies, embodiment of the present utility model is by the flexible PCB of button, and the side of metal dome increases elastic component, plays the purpose in compression diastema space, this Standard is simple, with low cost, has higher practical value in actual use.

Further, described elastic component is fixed on described flexible PCB, in order to stably to fix elastic component.

Further, described elastic component is provided with certain gap with the lower limb of described button, and after preventing assembling, elastic component top is to button.

Further, the distance in described gap is 0.1～0.2mm, uses rational line space design, makes button press down on and makes easily to touch elastic component and be not likely to produce diastema.

Further, described elastic component is annular, and described metal dome is positioned at the center of described elastic component, easy for installation.

Further, described elastic component comprises at least two part, and each several part is located on around described metal dome.

Further, described elastic component comprises two parts, and said two part is oppositely arranged on described metal dome both sides, connects simple, cost-effective.

Further, described elastic component comprises three parts, and described three parts are spacedly distributed around described metal dome.

Further, each several part of described elastic component is curved, corresponding with metal dome, arranges with arc and makes elastic component be unlikely to deform.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, 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 the present utility model, in order to make reader be more fully understood that, the application proposes many ins and outs.But, even if there is no these ins and outs and many variations based on 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 electronic equipment, shown in Fig. 1, this electronic equipment includes a housing 1, the button 2 being arranged on housing 1, and with button 2 with the use of flexible PCB 4, position corresponding with the conductive base of button 2 on flexible PCB 4 is provided with metal dome (i.e. DOME sheet 3), is provided with elastic component 5 between button 2 and flexible PCB 4, and elastic component 5 is distributed in around DOME sheet 3.

In actual applications, before button is installed, elastic component 5 is arranged at around DOME sheet 3, and be fixed on flexible PCB 4, on the housing 1 of the mobile phone that then button 2 is installed on the position of corresponding DOME sheet 3, install rear pressing keys 2 and just can play the purpose in compression diastema space, improve the feel of button 2, its simple in construction, low cost, there is higher practical value.

It is noted that elastic component 5 can be fixed on flexible PCB 4, such as, elastic component can be pasted onto on flexible PCB, in order to be stably fixed elastic component 5, in order to avoid coming off by double faced adhesive tape etc..Simultaneously, the lower limb of elastic component 5 and button 2 can reserve certain gap, and the distance in gap can be 0.1～0.2mm, uses rational line space design, making button 2 press down on makes button 2 lower limb easily touch elastic component 5 and be not likely to produce diastema, and after preventing assembling top to button 2.

Additionally, what deserves to be explained is, elastic component 5 can be annular, as in figure 2 it is shown, the elastic component 5 of this annular is located at DOME sheet 3 around, it is preferable that DOME sheet 3 can be located at the center of elastic component.

Additionally, the elastic component 5 that elastic component 5 is medium decrement on the low side, this elastic component 5 can be foam, so makes foam be unlikely to deform, and foam has certain elasticity to be resetted by button 2, makes button 2 the most more feel.In addition to using foam, it is also possible to use the elastic component 5 of the elastic material such as silica gel, rubber, determine according to actual needs, repeat the most one by one at this.

In use, owing to being arranged around elastic component 5 at DOME sheet 3, and elastic component 5 is fixed on flexible PCB 4, make to leave certain interval between the lower limb of elastic component 5 and button 2, push button 2 time, elastic component 5 is pressed down by button 2, have compressed the diastema space within button 2, improving the feel of mobile phone sidepiece button 2, not only device is simple, with low cost, uses field to have higher practical value at mobile phone.

Second embodiment of the present utility model relates to a kind of electronic equipment.Second embodiment and the first embodiment are roughly the same, are: in the first embodiment in place of the main distinction, and elastic component 5 is annular, and in this utility model the second embodiment, if elastic component 5 is divided into stem portion.

Specifically, if elastic component 5 is segmented into stem portion, each several part is distributed in around DOME sheet 3.Such as, elastic component 5 is set to discontinuous annular, such as block, DOME sheet 3 is located at the center of annular, block quantity can be two, three or more, as shown in Figure 3 and Figure 4, preferably, if elastic component 5 is divided into two parts, two parts can be symmetrically disposed in the opposite sides of DOME sheet 3；If elastic component is divided into three parts, DOME sheet 3 can be spaced apart and arranged in around, in order to reach more preferable effect, can be by bulk to be distributed equally spacedly, it is easy for installation and has saved cost, it is simple to compression diastema space is reached more preferable effect.

What deserves to be explained is, elastic component 5 is segmented into more polylith, can be according to installing complexity, or reality is improved the effect of diastema and determined, the most convenient explanation of above-mentioned number and enumerate, present embodiment is not limited to above-mentioned number.

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, can to it, various changes can be made in the form and details, without departing from spirit and scope of the present utility model.
