Abstract

A mobile phone button structure comprises a button body and a metal spring leaf arranged in a shell. The button body is a functional button arranged on the side wall of the shell, and the metal spring leaf comprises a bottom plate and wing-like main elastic arms up-warped symmetrically and arranged at the two ends of the bottom plate; one ends of the main elastic arms support the underside of the button body, the button body is convex, and the two ends of the underside of the button body are equipped with buckle ears symmetrically; a limiting column used for limiting the stroke of the button body is arranged in the shell, a positioning bone is protrudedly arranged in the shell and matches a positioning hole arranged on the metal spring leaf, and the positioning hole of the metal spring leaf is sleeved and fixed on the positioning bone. According to the utility model, by utilizing the metal spring leaf as an elastic member, the elasticity needed by the button function is realized, and at the same time, the button assembly pre-positioning purpose is achieved, thereby not only saving the space, but also being convenient for assembly; by arranging the grounding elastic arms on the metal spring leaf, the button grounding protection also can be realized; the mobile phone button structure is simple and reliable in structure, and is economic and practical.

Description

A kind of mobile phone press-key construction

Technical field

The utility model relates to a kind of press-key structure, particularly relates to a kind of press-key structure of mobile phone.

Background technology

Present mobile phone key, especially mobile phone side key on the market just used plastic cement material mostly, and elastic component also is to adopt Elastic plastic-rubber mostly, the side switch of this structure, and no matter in durability, all there is certain defective in crash resistance, and volume is bigger, and very inconvenience is installed also.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, installing space is little, mobile phone press-key construction easy to assembly.

In order to achieve the above object, the technical scheme of the utility model employing is:

A kind of mobile phone press-key construction; Comprise keying body, be arranged at the metal clips in the housing; This keying body is the function key that is arranged at housing sidewall; Said metal clips comprises base plate and upwarps and be arranged at the spademan shape master elastic arm at base plate two ends symmetrically that said main elastic arm one end is supported in the bottom surface with keying body; Said keying body is convex shape, and its two ends, bottom surface are symmetrically arranged with buckle ear, is provided with the limited post in order to restriction keying body stroke in the said housing.

Further, said housing internal projection is provided with the location bone, and this location bone is complementary with the location hole that is arranged on the metal clips, and the location borehole jack of metal clips is fixed on the bone of location.

Further, also be respectively arranged with grounding elastic part on the said main elastic arm.

Further, said keying body and the inconsistent position of main elastic arm are symmetrically arranged with 2 track shape and press counterbore.

Further, said pressing also convexes with the contact that is used to trigger touch-switch between two parties between the counterbore.

The utility model utilizes metal clips as elastic component; Realize the required flexible pre-determined bit purpose that also reaches the button assembling simultaneously of keypress function, not only save the space, can also ease of assembly; The ground connection elastic arm that is provided with on the metal clips; Also can realize the ground protection of metal key-press, simple and reliable for structure, economical and practical.

Description of drawings

Fig. 1 is the mounting structure sketch map of the utility model;

Fig. 2 is the assembly structure sketch map of keying body and metal clips;

Fig. 3 is the structural representation of metal clips.

Shown in the figure be: the 1-contact; The 2-keying body; The 3-buckle ear; The 4-housing; The 5-limited post; 6-locatees bone; The 7-touch-switch; The 8-mainboard; 9-presses counterbore; The 10-metal clips; The 11-location hole; 12-master's elastic arm; The 13-grounding elastic part; The 14-base plate.

Embodiment

For the ease of those skilled in the art's understanding, the utility model is done further to describe below in conjunction with accompanying drawing.

A kind of mobile phone press-key construction shown in Fig. 1 to 3; Comprise keying body 2, be arranged at the metal clips 10 in the housing 4; This keying body 2 is for being arranged at the function key of housing 4 sidewalls; Said metal clips 10 comprises base plate 14 and upwarps and be arranged at the spademan shape master elastic arm 12 at base plate 14 two ends symmetrically that said main elastic arm 12 1 ends are supported in the bottom surface with keying body 2;

Said keying body 2 is convex shape, and its two ends, bottom surface are symmetrically arranged with buckle ear 3, is provided with the limited post 5 in order to restriction keying body 2 strokes in the said housing 4, particularly, and this limited post 5 and buckle ear 3 interferences, the stroke of restriction keying body 2.

Said housing 4 internal projection are provided with location bone 6, and this location bone 6 is complementary with the location hole 11 that is arranged on the metal clips 10, and location hole 11 covers of metal clips 10 are fixed on the bone 6 of location.

Also be respectively arranged with grounding elastic part 13 on the said main elastic arm 12, be used for keying body is imposed ground protection.

Said keying body 2 is symmetrically arranged with 2 track shape with main elastic arm 12 inconsistent positions and presses counterbore 9, saves the space, plays the hanging platform effect simultaneously, ease of assembly.

Said pressing also convexes with the contact 1 that is used to trigger touch-switch 7 between two parties between the counterbore 9.

The operation principle of the utility model is following: keying body 2 is when armed state; 2 main elastic arms 12 of metal clips 10 are closely conflicted with it; Keying body 2 that makes and contact 1 thereof are away from the touch-switch 7 that is installed on the mainboard 8; Simultaneously, under the limited post 5 obstruction effects of the buckle ear 3 on the keying body 2 in housing 4, make keying body 2 keep static in the precalculated position; When using keying body 2; Keying body 2 moves to touch-switch 7 directions under external force, and the contact 1 on the keying body 2 triggers touch-switch 7, simultaneously; Grounding elastic part 13 on the main elastic arm 12 is conflicted with the earth terminal elasticity that is arranged on the mainboard 8, realizes the ground protection to keying body 2.After external force disappeared, keying body 2 away from touch-switch 7, and kept under the aforesaid armed state under the elastic reaction of metal clips 10.

The above is a preferred embodiment of the utility model, is not breaking away under the utility model design situation, carries out any conspicuous distortion and replacement, all belongs to the utility model protection range.
