Abstract

This utility model relates to a kind of button, including: the button cap combined and key main body, button cap is above key main body；Waterproof case, described waterproof case annular is around described key main body；Elastic arm, described elastic arm connects described waterproof case and described key main body hermetically.This utility model is prevented under button intaking on time.

Description

A kind of button

Technical field

This utility model relates to a kind of button.More particularly, to a kind of button that can be waterproof.

Background technology

Now for being provided with the waterproof problem of button on panel, a solution of prior art is typically to use silica gel Button comes waterproof, and silica gel push-button and housing interference fit reach waterproof purpose, but when button is pressed, button and housing Produce gap, it is impossible to waterproof.

Another solution of prior art is that this part of increase is by silica gel push-button by increasing a part It is locked on part or housing to reach waterproof purpose, but this method increases part and assembly work, add manufacturing cost, And the part increased needs to take bigger space, the miniaturization for equipment is unfavorable.

Utility model content

For the problems of the prior art, the utility model proposes a kind of button, including: the button cap combined and Key main body, button cap is above key main body；Waterproof case, described waterproof case annular is around described key main body；Elastic arm, institute State elastic arm and connect described waterproof case and described key main body hermetically.

Alternatively, the upper end of described waterproof case is concordant with key main body.

Alternatively, described elastic arm connects described waterproof case and described key main body obliquely.

Alternatively, described waterproof case and described elastic arm are made up of silica gel.

Alternatively, described button also includes: stop part, and described stop part is from button cap outwardly.

Alternatively, state button cap and described key main body is that removably the plug of described button cap lower end is inserted into As in the described key main body of socket.

Alternatively, one end that described elastic arm connects described key main body is high, and the one end connecting described waterproof case is low.

Alternatively, button cap and waterproof case are bonded together by glue.

Advantage of the present utility model includes: prevent button from pressing strength is too big and cause cannot be waterproof, water drains on PCB. Button is waterproof to be reached by pcb board pressure water-proof silica-gel part, is increased without new part to press water-proof silica-gel part, not only subtracts Having lacked at least one part, also a saving space simultaneously, product be can be made smaller.

Detailed description of the invention

Describing embodiment of the present utility model with reference to the accompanying drawings, the most identical parts are with identical reference table Show.

As it is shown in figure 1, button of the present utility model includes button cap 1, key main body 5, waterproof case 3 and elastic arm 4.Button Cap 1 and key main body 5 are one-body molded.Waterproof case 3 annular is connected to button around key main body 5, waterproof case 3 by elastic arm 4 In main body 5.Elastic arm 4 can be connected to button cap 1 and the junction of key main body 5.Waterproof case 3 and elastic arm 4 can be by silicon Glue is made.

Alternatively, button cap 1 is such as bonded together by glue with waterproof case 3.

Alternatively, the height of the aspect ratio button cap 1 of waterproof case 3 is low.Preferably concordant with key main body 5.

Alternatively, elastic arm 4 connects key main body 5 and waterproof case 3 obliquely, is shown as elastic arm 4 and connects button in figure One end of cap 1 is high, and the one end connecting waterproof case 3 is low.When unclamping after the cap 1 that pushes button, 4 button caps 1 of elastic arm spring back to former Come position.

After button shown in Fig. 1 is according on panel, button cap 1 by press under external force move downward time, button cap 1 band is moved Property arm 4 move downward, even if there being water to enter, also being accepted by elastic arm 4, it is impossible to arrive at key main body 5, reaching waterproof purpose.

Fig. 2 shows another embodiment of button of the present utility model, and described button can also include stop part 2, Stop part 2 is from button cap 1 edge outwardly.Stop part 2 fit applications environment can limit the movement travel of button cap 1.

Fig. 3 shows the schematic diagram of another embodiment of button of the present utility model.Unlike Fig. 2, button Cap 1 and key main body 5 are to separate, and the plug 9 of the lower end of button cap 1 is inserted into as in the key main body 5 of socket, as This, can change the button cap 1 being easier to abrasion, and without changing waterproof case 3 and key main body 5.

Fig. 4 shows the application schematic diagram of button of the present utility model.Waterproof case 3 is pressed onto on housing 7 by pcb board 8.Housing It is that interference fit is with waterproof between 7 and waterproof case 3.Housing 7 can have in the protruding respective slot to insert waterproof case 3 with reality Existing interference fit.

It addition, the stroke that button cap 1 is pressed is limited by panel 6 and housing 7, i.e. stop part 2 is at panel 6 and housing 7 Move up and down in the space limited.It addition, stop part 2 and panel 6 and the cooperation of housing 7, additionally it is possible to prevent button pressed stroke Button two ends water inlet too greatly.

Embodiment described above, simply this utility model more preferably detailed description of the invention, those skilled in the art The usual variations and alternatives carried out in the range of technical solutions of the utility model all should be included in protection domain of the present utility model In.
