Abstract

The utility model relates to a button structure which comprises a button body matched with a casing. The button body is connected with the casing through a concave-convex matched structure. The concave-convex matched connection structure reduces the length of the button body, can reduce the thickness of the button body, and can thoroughly block static electricity to remove mobile phone faults caused by the static electricity due to the fact that the periphery of the button of the casing is completely sealed.

Description

A kind of press-key structure

Technical field

The utility model relates to a kind of press-key structure.

Background technology

Existing button generally adopts PC+PTU material double-shot moulding, and in order to ensure pressing the bond energy effective location, usually can two hanging platforms be set at the two ends, the left and right sides of button, at the inboard connecting portion that cooperates with two hanging platform overlap joints that arranges of housing, then from the inboard assembling of housing.This press-key structure has obvious defective: at first since button need to increase about two hanging platforms, the space that length direction takies is larger; Secondly, button need to be from the inboard assembling of housing, and thickness direction takes up room larger, and the button part is owing to expecting that the problem of shrinking appears in thick reason easily; Again, housing need to be opened larger position, hole and make things convenient for button to pack into, has affected casing rigidity; In the actual design process, the shirt rim of button can be jagged again, and static might enter interior of mobile phone from the slit of button and housing, cause fault of mobile phone.

The utility model content

The technical problems to be solved in the utility model is, for the defects of prior art, provides a kind of press-key structure.

The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of press-key structure, comprise the keying body that cooperates with housing, described keying body is connected by concave-convex fit structure with described housing.

Press-key structure described in the utility model, wherein, described concave-convex fit structure comprises and is arranged on the lug boss on the described keying body and is arranged on the depressed part that cooperates with described lug boss on the described housing that described keying body is connected with described housing with the cooperation of described depressed part by described lug boss.

Press-key structure described in the utility model, wherein, described concave-convex fit structure comprises and a plurality ofly is convexly equipped with at the cylinder on the described keying body and is opened in the perforate that cooperates with a plurality of described cylinders on the described housing that described keying body is connected with described housing by the cylinder that is inserted in the described perforate.

Press-key structure described in the utility model, wherein, described cylinder comprises having flexible cylinder.

Press-key structure described in the utility model wherein, has at least a described cylinder to be provided with for spacing fimbriatum, and described fimbriatum has elasticity.

Implement press-key structure of the present utility model, have following beneficial effect: the concavo-convex structure that is connected has reduced the length of keying body, and can reduce the thickness of keying body, and has been hermetic around the button of housing, can thoroughly block static, eliminate the fault of mobile phone that causes because of static.

Embodiment

As Figure 1-3, in preferred embodiment of the present utility model, this press-key structure comprises the keying body 100 that cooperates with housing 200, and this keying body 100 and housing 200 are connected by concave-convex fit structure.

Preferably, concave-convex fit structure can comprise and be arranged on the lug boss on the keying body 100 and be arranged on the depressed part that cooperates with lug boss on the housing 200 that keying body 100 is connected with housing 200 with the cooperation of depressed part by lug boss.At first, in keying body 100 lug boss is set, and at housing 200 depressed part is set, can be so that the assembly crewman namely can finish the assembling to keying body 100 in the outside of housing 200, improve efficiency of assembling, also reduced button taking up room on thickness direction simultaneously; Secondly, keying body 100 has reduced taking up room of length direction; Again, owing to not be used on the keying body 100 breach is set, has eliminated static and from the slit of keying body and housing, entered interior of mobile phone, cause the hidden danger of fault of mobile phone.

Shown in Fig. 1,3,4 and 5, at the utility model further among the embodiment, concave-convex fit structure can also be a plurality ofly to be convexly equipped with the cylinder 101 on institute's keying body 100 and to be opened in the perforate 201 that cooperates with a plurality of cylinders 101 on the housing 200, and keying body 100 is connected with housing 200 by the cylinders 101 that are inserted in the perforate 201.In actual design process, cylinder 101 can be itself to have flexible cylinder 101, this just means that cylinder 101 has certain compression surplus, be inserted into perforate 201 interior after, because it has the characteristic of recovering deformation, therefore can seal the gap that may exist between cylinder 101 and the perforate 201, eliminate static and from the slit of keying body and housing, entered interior of mobile phone, cause the hidden danger of fault of mobile phone.

In addition, come off from housing 200 in order to prevent keying body 100, have at least a cylinder 101 to be provided with for spacing fimbriatum 102, this fimbriatum 102 also has elasticity.When assembling, the outside at housing 200, with the perforate 201 on the cylinder 101 aligning housings 200, and be inserted in the perforate 201, because fimbriatum 102 has elasticity, therefore also can in perforate 201, pass, after waiting to pass completely through, fimbriatum 102 restores to the original state, so that keying body 100 is locked on the housing 200.

Said structure has reduced the length of keying body 100, and can reduce the thickness of keying body 100, only need to open several apertures on the housing 200, the intensity of housing 200 scheme as compared with the past obviously strengthens, and be hermetic around the button of housing 200, can have thoroughly blocked static.

Above embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and accordingly enforcement, can not limit protection range of the present utility model.All equalizations of doing with the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
