Abstract

The utility model discloses a keystroke structure of a three-protection mobile phone which includes the keystroke and a plastic shell body; the silica gel part of the keystroke and the plastic shell body are integrally shaped. The utility model provides a structure mode that the plastic shell and the silica gel part of the keystroke are integrally shaped based on fully researching the current keystroke technique so as to lead the silica gel part of the keystroke and the plastic shell to be closely combined for preventing water and dust to enter, thus leading the device to be capable of achieving the highest requirements of three-protection, namely being capable of dust protection of six grade and water protection of nine grade. The error and unreliability caused by assembly are avoided; the reliability of the keystroke and the plastic shell are increased; the requirements for seal design are completely achieved.

Description

The press-key structure of three anti-mobile phones

Technical field

The utility model relates to press-key structure, particularly a kind of button and the conjuncted frame mode of casing of three anti-mobile phones.

Background technology

Three anti-mobile phones have mobile phone slight dustproof, shockproof, water-proof function exactly, are always had deep love for the young user of outdoor exercises deeply and like.Because its unique NBC protective performance has satisfied customer demand, market demand is very big, and a lot of domestic consumers all wish to have one one three anti-mobile phone, so that can still can normally use under special environment.Three anti-mobile phones are in waterproof, a weak spot of dustproof aspect is the button position, be subjected to the restriction of the manufacturing process and the assembly technology of button, the present button waterproof type that generally adopts all can't be accomplished very reliable, can't satisfy the three anti-more and more harsh requirements in aspect.

As Fig. 1, traditional general mode that adopts of three anti-mobile phones is (as the pressure of pcb board by external force, mould the coupling mechanism force of shell etc.) silicon gel part 4 of button is compressed sealing (perhaps adopting glue 3 bondings) moulding on the shell body 1, no matter being from front assembling or assembling from the negative, all is to adopt this mode.

The utility model content

The technical problems to be solved in the utility model is in order to overcome the mobile phone three anti-insecure defectives of function in the prior art, the press-key structure of a kind of three anti-mobile phones to be provided.

The utility model solves above-mentioned technical problem by following technical proposals:

The press-key structure of a kind of three anti-mobile phones, it comprises button and moulds the shell body, and its characteristics are, and the silica gel portion of this button and this mould that the shell body is formed in one.

Wherein, this button also comprises plastic section, the contact-making surface adhesive bond of the plastic section of this button and silica gel portion.

Positive progressive effect of the present utility model is:

1, fully studying on the basis of present button technology, a kind of shell and integrated frame mode of button silicon gel part moulded proposed, so that button silicon gel part and mould shell and combine closely, entering of anti-sealing and dust, make this position can reach three anti-peak demands, can accomplish that promptly six grades are prevented dust nine grades of waterproof.

2, avoided the sum of errors that causes because of assembling unreliable, the reliability that has increased button and moulded shell, and reached the requirement of Seal Design fully.

Description of drawings

Fig. 1 is the fit figure of button in the prior art.

Fig. 2 is the button installation diagram of the utility model one embodiment.

Fig. 3 is the button installation diagram of another embodiment of the utility model.

Embodiment

Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

Embodiment 1

One, structure is formed

Present embodiment is the press-key structure mode (being the combination of plastics and silica gel) of P+R, and as shown in Figure 2, button is formed by parts of plastics 2 and silicon gel part 4 bondings, and the silicon gel part 4 of button with mould that shell body 1 is formed in one.

Two, manufacture craft

The concrete manufacture craft of said structure is as follows.

At first, by extra quality moulding process with mould shell body 1 and carry out one-body moldedly, both seal fully in formation with the silicon gel part 4 of button.

Then, the parts after the moulding are assembled to button produce in the anchor clamps, be assembled on the silicon gel part 4 according to the button technology (being the combination of plastics and silica gel) of P+R parts of plastics 2 with button.

Before assembling, the parts of plastics 2 of button needs through spraying, oil spout and follow-up PROCESS FOR TREATMENT such as laser engraving.And general mode of the prior art the time is adopted in assembling, is about to the parts of plastics 2 of button and silicon gel part 4 on special fixture, carries out with the mode of glue bonding.

At last, assembly work finishes, and has just formed a button and has moulded the press-key structure of shell one.

Embodiment 2

One, structure is formed

As shown in Figure 3, present embodiment is that with the different of embodiment 1 button has only adopted silicon gel part 4 (hereinafter referred to as button silica gel 4), does not adopt parts of plastics, so directly button is called silica gel push-button here.Button silica gel 4 with mould shell body 1 one-body molded after, directly as next step technology basis.

Two, manufacture craft

The concrete manufacture craft of said structure is as follows.

At first, button silica gel 4 by extra quality moulding mode and mould shell body 1 carry out one-body molded, in the hope of reaching and moulding the effect that shell body 1 seals fully.

Then, the parts after the moulding carry out the needed spraying of silica gel push-button, oil spout, processing such as laser engraving as next step technology basis of silica gel push-button.

At last, just form a silica gel push-button and moulded the press-key structure of shell one.

Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these execution modes.Therefore, protection range of the present utility model is limited by appended claims.

Claims

1, the press-key structure of a kind of three anti-mobile phones, it comprises button and moulds the shell body, it is characterized in that, the silica gel portion of this button and this mould that the shell body is formed in one.

2, the press-key structure of as claimed in claim 1 three anti-mobile phones is characterized in that this button also comprises plastic section, the contact-making surface adhesive bond of the plastic section of this button and silica gel portion.
