Abstract
The utility model relates to a waterproof device for a key, which comprises a group of keys, a soft pad, and a casing. The keys are sheathed in holes of the casing, and the keys are all connected; the soft pad is covered and tightly fixed at the back sides of the keys in a sticking way, and the soft pad is provided with a plurality of round holes rightly relative to the back sides of the key so as to penetrate and place convex points at the back sides of the keys; the soft pad can be plastic elastic materials, and can causes a no gap state to be formed between the keys and the casing so as to prevent water or water vapour to enter the casing and influence the normal work of a circuit on a circuit board in the casing.
Description
The utility model relates to a kind of water-tight device of button.
Please refer to shown in Fig. 1,2, it is general known keypad device of mobile phone, and it mainly is the hole (11) that button (2) is sheathed on phone housing (1), and by salient point (21) the contact circuit plate (4) at button (2) back, message is imported in induction again.
So, this kind mobile device is if often place the wetness height, or mobile phone is met water because of carelessness during rainy day, and water and aqueous vapor all can be infiltrated mobile phone inside via the button (2) and the trickle space of phone housing (1), and influence circuit board (4) operation system in the mobile phone.
The purpose of this utility model aims to provide a kind of water-tight device of button, can make the seamless state of formation between button and shell, enters shell to prevent water or aqueous vapor, and influences the normal operation of the circuit on the circuit board in the shell.
In order to achieve the above object, the utility model provides a kind of water-tight device of button, it is characterized in that: it comprises one group of button, a cushion and a shell:
This shell is provided with most and button corresponding perforations, and this button is placed through the hole place of shell, and this button front protrudes from this hole;
This cushion covers and closely pastes and is fixed in the button back side.
The water-tight device of described button is characterized in that: this cushion can be a plastic cement elastic water-proof pad, and is provided with most circular holes just with respect to the salient point at the button back side, places for the salient point at the button back side.
The water-tight device of button of the present utility model includes one group of button, a cushion and a shell; Button is sheathed on the hole of shell, and all is connected between button, to increase the stationarity of button; This cushion can be a plastic cement elastic water-proof pad, covering is pasted and is fixed in the button back side, and on cushion with respect to the salient point place, be provided with most circular holes, salient point for the button back side penetrates, the cushion of plastic cement elastic material can fit tightly more with shell and button back side salient point, makes between the external world and circuit board to become almost seamless state, prevents that into water and aqueous vapor influence Circuits System.
For structure of the present utility model and the effect that reached are had clear and definite more full and accurate understanding and understanding, be described in further detail below with reference to the accompanying drawing illustrated embodiment.
The simple declaration of accompanying drawing drawing:
Fig. 1 is the press-key structure exploded view of commonly using.
Fig. 2 is the press-key structure cutaway view of commonly using.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 5 is a structure cutaway view of the present utility model.
At first, please refer to Fig. 3,4, the water-tight device of button of the present utility model, it includes a shell (1 '), one group of button (2) and a cushion (3);
This shell (1 ') is to be provided with most holes (11 '), and the just relative button (2) in the position of this hole (11 ') places for button (2).
This button (2) is the hole (11 ') that is placed through shell (1 ') just, and all be connected between button (2) and button (2), to increase the stationarity of button (2), button (2) back side is equipped with salient point (21), for the user when button (2), salient point (2) contact circuit plate (4) via the back side carries out the running of Circuits System.
This cushion (3) is that to can be a plastic cement elastic water-proof material made, covers to paste and is fixed in button (2) back side, and be provided with most circular holes (31) in cushion (3), penetrates for the salient point (21) at button (2) back side, as shown in Figure 5.
By hole (the 11 ') Hou that places shell (1 ') at button (2), again the cushion (3) of plastic cement elastic material is closely pasted and be fixed on button (2) back side, shell (1 ') is fixed in button (2) applying, and be provided with most circular holes (31) in cushion, just can supply the salient point (21) at button (2) back side to place, because the material of cushion elastic water-proof, can make cushion can fit closely shell (1 ') and salient point (31), make the almost seamless state of formation between extraneous and circuit board (4), prevent that into water and aqueous vapor influence Circuits System.
Claims (2)
1. the water-tight device of a button, it is characterized in that: it comprises one group of button, a cushion and a shell:
This shell is provided with most and button corresponding perforations, and this button is placed through the hole place of shell, and this button front protrudes from this hole;
This cushion covers and closely pastes and is fixed in the button back side.
2. the water-tight device of button as claimed in claim 1, it is characterized in that: this cushion is a plastic cement elastic water-proof pad, and is provided with most circular holes just with respect to the salient point at the button back side, places for the salient point at the button back side.
