Description

A kind of water-proof type button operation face equipment

Technical field

The utility model relates to electric device housings, relates in particular to a kind of water-proof type button operation face equipment.

Background technology

The structure of the button operation face equipment of general electronic equipment comprises face-piece 1, drain pan 2 and button piece 3 as depicted in figs. 1 and 2, and face-piece 1 links to each other with drain pan 2 and constitutes a box body, and a pcb board 4 is installed in the box body, a plurality of touch-switchs 41 of installing on the pcb board 4.

As shown in Figure 2, face-piece 1 is offered a plurality of keyholes 10, is convexly equipped with a plurality of buttons 30 on the button piece 3, and button piece 3 is installed between face-piece 1 and the pcb board 4, and button 30 snaps in the corresponding keyhole 10.

As shown in Figure 2, button 30 comprises the relative sealing marginal ridge 302 around briquetting 301 with of a briquetting 301, briquetting 301 directly supports the top to corresponding touch-switch 41, closure flange 101 is set up in keyhole 10 inboards, the outward flange to button 30 marginal ridges 302 is supported in flange 101 ends, in the prior art, conflict by the plane between closure flange 101 and the marginal ridge 302, aqueous vapor is isolated from outside the marginal ridge 302, but in use, during pressing keys 30, have relative motion between marginal ridge 302 and edge thereof and the face-piece 1 (flange 101), flange 101 produces with marginal ridge 302 edges and separates, aqueous vapor can be penetrated in (box body) inner chamber in the slit when separating, cause the internal electron line short, therefore, the prior art water resistance is not good enough.

Summary of the invention

The purpose of this utility model is to provide a kind of water-proof type button operation face equipment, to overcome the not good enough shortcoming of water resistance in the prior art.

The water-proof type button operation face equipment that the utility model adopted comprises face-piece, drain pan and button piece, and face-piece links to each other with drain pan and constitutes a box body, and a pcb board is installed in the described box body, installs a plurality of touch-switchs on the described pcb board at least;

Described face-piece is offered a plurality of keyholes, is convexly equipped with a plurality of buttons on the described button piece, and button piece is installed between face-piece and the pcb board, and described button snaps in the corresponding keyhole,

Wherein, described button comprises the relative sealing marginal ridge around briquetting with of a briquetting, and the briquetting of each button directly supports the top to corresponding touch-switch;

Closure flange is set up in described keyhole inboard, and described flange end is supported the outward flange to the button marginal ridge, and it is characterized in that: corresponding sealing triangle muscle is set up on the flange top of described keyhole, and described triangle muscle embeds the outward flange of marginal ridge.

Described triangle muscle and the integrated parts of flange.

The beneficial effects of the utility model are: in the utility model, closure flange is set up in the keyhole inboard, corresponding sealing triangle muscle is set up on the flange top of keyhole, triangle muscle on the flange is directly replaced the outward flange of button marginal ridge, the triangle muscle embeds the outward flange of marginal ridge, the utility model utilizes face-piece, interference close fit between button piece and the pcb board, make between face-piece and the button piece and produce assembling pressure, thereby make the distortion of (silicon rubber) marginal ridge outward flange relevant position, to adapt to the triangle of triangle muscle, be equivalent between the outward flange of triangle muscle and marginal ridge, apply a pre-pressing force, when pressing keys, the dispose procedure of pre-pressing force can be guaranteed to keep the conflict state between the outward flange of triangle muscle and marginal ridge, avoids separating the generation in slit, makes the utility model obtain favorable waterproof property.

In the utility model, the integrated parts of triangle muscle and flange have further improved reliability of the present utility model and practicality.

Embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

According to Fig. 3, Fig. 4 and Fig. 5, the utility model comprises face-piece 1, drain pan 2 and button piece 3, and as shown in Figure 3, face-piece 1 links to each other with drain pan 2 and constitutes a box body, and a pcb board 4 is installed in the box body, a plurality of touch-switchs 41 of installing and corresponding LED lamp 42 on the pcb board 4.

As Fig. 3, Fig. 4 and shown in Figure 5, face-piece 1 is offered a plurality of keyholes 10, is convexly equipped with a plurality of buttons 30 on the button piece 3, and button piece 3 is installed between face-piece 1 and the pcb board 4, and button 30 snaps in the corresponding keyhole 10.

As shown in Figure 3 and Figure 4, button 30 comprises the relative sealing marginal ridge 302 around briquetting 301 with of a briquetting 301, and the briquetting 301 of each button 30 directly supports the top to corresponding touch-switch 41.

As Fig. 3, Fig. 4 and shown in Figure 5, closure flange 101 is set up in keyhole 10 inboards, corresponding sealing triangle muscle 102 is set up on flange 101 tops, triangle muscle 102 and flange 101 integrated parts, sealing triangle muscle 102 is directly replaced the outward flange of button 30 marginal ridges 302, and triangle muscle 102 embeds the outward flange of marginal ridge 302.

Present embodiment is the interference close fit between face-piece 1, button piece 3 and pcb board 4, make between face-piece 1 and the button piece 3 and produce assembling pressure, thereby make the distortion of (silicon rubber) marginal ridge 302 outward flange relevant positions, to adapt to the triangle of triangle muscle 102, be equivalent between the outward flange of triangle muscle 102 and marginal ridge 302, apply a pre-pressing force, when pressing keys 30, the dispose procedure of pre-pressing force can guarantee to keep between the outward flange of triangle muscle 102 and marginal ridge 302 the conflict state.

In sum, although basic structure of the present utility model is specifically set forth by the foregoing description, under the prerequisite that does not break away from the utility model main idea, according to above-described inspiration, those of ordinary skills can not need to pay creative work can implement multiple conversion/alternative form or combination, repeats no more herein.
