Preferably, described side switch portion comprises conductive base, and described conductive base is corresponding with the position of the key contacts on cell phone mainboard through perforate.
Preferably, described conductive base comprises two columniform press sections corresponding with the key contacts on cell phone mainboard respectively, and the connecting portion of square column type that two ends are connected with press section sidewall respectively.
Preferably, the base inside described button portion supporting surface corresponding housing is provided with reinforced glue.Make the fixing more firm of side switch and housing like this, simultaneously because reinforced glue is arranged on the position base of supporting surface and case inside, can avoid adding strong rubber like this and the perforation inner side colloid shape that easily appearance is elongated is set, affect the situation that mobile phone is attractive in appearance.
Preferably, base is provided with in described housing, described base is provided with through hole, the hook part that described fixed part comprises the cylinder that supporting surface extends, described cylinder far-end extends along column vertical direction, described hook part is hooked in base back surface through through hole, and the edge of the side that described cylinder is adjacent with hook part and described through hole leaves the space pressing movement for side switch; Extend a carriage from case inside along perforation edge, described carriage one end is fixedly connected with shell frame; The other end is connected with base, described button portion is partially submerged in support frame, described supporting surface drops on base, described side switch portion comprises conductive base, base is provided with the opening of dodging described conductive base, described conductive base is corresponding with the position of the key contacts on cell phone mainboard through perforate, described conductive base comprises two columniform press sections corresponding with the key contacts on cell phone mainboard respectively, and the connecting portion of square column type that two ends are connected with press section sidewall respectively, the base inside described button portion supporting surface corresponding housing is provided with reinforced glue.
Supporting surface size of the present utility model is less than perforation, overall can pass through to the perforation of shell frame, therefore the fixed part of mobile phone side key can be embedded into case inside from hull outside by perforation, and be fixedly connected with case inside, make side switch like this in assembling process, the installation of side switch can not be affected because of case inside narrow space, side switch can be made like this to assemble easier, reduce assembly difficulty greatly, effectively raise the production efficiency of mobile phone, reduce production cost.

Detailed description of the invention
A kind of mobile phone side key, described mobile phone side key is arranged on housing, described mobile phone side key comprises button portion, described button portion comprises a supporting surface, described supporting surface extends fixed part, the frame of described housing is provided with perforation, and described supporting surface embeds perforation from hull outside, and described fixed part is fixed on case inside.
The utility model is owing to adopting this structure, mobile phone side key is arranged a fixed part, fixed part is embedded into case inside from hull outside by perforation, and be fixedly connected with case inside, make side switch like this in assembling process, the installation of side switch can not be affected because of case inside narrow space, side switch can be made like this to assemble easier, reduce assembly difficulty greatly, effectively raise the production efficiency of mobile phone, reduce production cost.
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
According to Fig. 1, for the utility model is a kind of mobile phone side key, mobile phone side key comprises button portion 1, button portion 1 comprises a supporting surface 11, supporting surface 11 extends fixed part 2, the frame of housing 8 is provided with perforation 4, and supporting surface 11 embeds perforation 4 from hull outside, and fixed part 2 is fixed on inside housing 8.
Mobile phone side key is arranged a fixed part 1, fixed part 1 is embedded into inside housing 8 by perforation 4 outside housing 8, and be fixedly connected with inside housing 8, make side switch like this in assembling process, the installation of side switch can not be affected because of case inside narrow space, side switch can be made like this to assemble easier, reduce assembly difficulty greatly, effectively raise the production efficiency of mobile phone, reduce production cost.
According to Fig. 2, a carriage 6 is extended along perforation 4 edge inside housing 8, carriage 6 one end is connected one end with housing 8 frame and is connected with base 7, button portion 1 is partially submerged in carriage 6 body, supporting surface 11 drops on base 7, and the base 7 inside supporting surface 11 corresponding housing 8 is provided with reinforced glue.
Side switch is trapped among in the framework that formed by carriage 6 and base 7, add side switch and base joint face, the bonding strength that can strengthen side switch and housing like this, increase the intensity of housing 8, avoid because side switch is directly connected with the direct openwork part in housing 8 side, cause housing 8 edge weak, the situation of easy fracture, base inside supporting surface 11 corresponding housing 8 is provided with reinforced glue, make the fixing more firm of side switch and housing 8 like this, simultaneously because reinforced glue is arranged on base 7 position inside supporting surface 11 and housing 8, can avoid adding strong rubber like this and the colloid shape that inside perforation 4, easily appearance is elongated is set, affect the situation that mobile phone is attractive in appearance.
According to Fig. 3,4, base 7 is provided with in housing 8, fixed part 1 is fixedly connected with base 7, fixed part 1 is the hook part 22 that the cylinder 21 that extends of supporting surface 11 and described cylinder 21 far-end extend along cylinder 21 vertical direction, base 8 is provided with through hole 5, hook part 22 is hooked in the back side of base 7 through through hole 5, and the edge of the side that cylinder 21 is adjacent with hook part 22 and through hole 5 leaves the space pressing movement for side switch, and button portion 1 and fixed part 2 are that full hard plastic is one-body molded.
