Abstract
The invention provides a waterproof plug for a side key of a mobile phone. A rigid sheet is arranged at the elastic bottom of the waterproof plug. The waterproof is similarly bowl-shaped. The rigid sheet is embedded outside the bowl bottom of the bowl-shaped waterproof plug. The thickness of the rigid sheet is 1/3 to 1/6 of that of the elastic bottom of the waterproof plug. A body of the waterproof plug is made of silica gel, and the rigid sheet is made of a steel sheet. The steel sheet is embedded at the elastic bottom of the waterproof plug in an in-mold injection molding way, and contacts a mainboard switch when the waterproof plug of the side key is pressed by a support pillar of a keycap. Annular grooves are formed in the bowl of the bowl-shaped waterproof plug to facilitate the elastic deformation of the elastic bottom. The in-mold injection-molded steel sheet is used for the silica gel product, so that the strength of a corresponding position is strengthened, and the service life of the waterproof plug is prolonged.
Description
Technical field
The present invention relates to the mobile phone technique field, relate in particular to the structure of the side switch waterproof plug that is used for mobile phone.
Background technology
The side switch water-proof silica-gel plug of existing mobile phone, the keycap support column by depressing, touch the switch (switch) on the mainboard, realize switch motion.Because the material of silica gel is soft, intensity and poor toughness, the keycap support column be easy to break by depressing repeatedly, thereby influence the air-tightness of side switch feel and mobile phone.
Summary of the invention
The technical problem that the present invention will solve is: the deficiency to above-mentioned existing mobile phone technique exists, a kind of structure that increases silica gel product intensity is provided, and prolong the useful life of waterproof plug.
The technical scheme that the present invention is directed to the problems referred to above and propose is: a kind of mobile phone is with side switch waterproof plug, and the elastic bottom of said waterproof plug is provided with stiff sheet.
Wherein, said stiff sheet is embedded in the elastic bottom of waterproof plug through in-mould injection.Said stiff sheet receives contacting by depressing with the mainboard switch of keycap support column at side switch waterproof plug.
The thickness of said stiff sheet be waterproof plug elastic bottom thickness 1/3rd to sixth.
The bulk material of said waterproof plug is a silica gel.The material of said stiff sheet is a steel disc.
Said waterproof plug is approximate bowl-shape, and said steel disc is embedded in the outside, the bowl end of bowl-shape waterproof plug.
Be provided with the ring-shaped groove of being convenient to the elastic bottom strain in the bowl of said bowl-shape waterproof plug, said ring-shaped groove at the bowl wall and at bowl the end.
The bowl wall of said bowl-shape waterproof plug is cylindrical, and the bowl edge of said bowl-shape waterproof plug is oval tabular.
Compared with prior art, adopt the advantage of technical scheme of the present invention to be: 1,, to increase the intensity of silica gel product relevant position, prolong the useful life of waterproof plug through using the in-mould injection steel disc.2, simple in structure, low cost of manufacture.

Fig. 3 is the rearview of mobile phone of the present invention with the embodiment of side switch waterproof plug.
Fig. 4 is the vertical view of mobile phone of the present invention with the embodiment of side switch waterproof plug.
Fig. 5 is the use sketch map of mobile phone of the present invention with the embodiment of side switch waterproof plug.
Comprise among the figure: elastic bottom 1, stiff sheet 2, ring-shaped groove 3, bowl wall 4, bowl edge 5, keycap support column 6, mainboard switch 7.
Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better,, the present invention is done further detailed description below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the front view of mobile phone of the present invention with the embodiment of side switch waterproof plug, and Fig. 2 is the AA cutaway view of Fig. 1, and Fig. 3 is the rearview of embodiment, and Fig. 4 is the vertical view of embodiment.Fig. 5 is the use sketch map of present embodiment.
Mobile phone is provided with stiff sheet 2 with the elastic bottom 1 of side switch waterproof plug, the thickness of stiff sheet 2 be the waterproof plug elastic bottom 1 thickness 1/3rd to sixth.The bulk material of waterproof plug is a silica gel, and the material of stiff sheet 2 is a steel disc.
Among the figure, side switch waterproof plug is approximate bowl-shape, and steel disc is embedded in the outside, the bowl end of bowl-shape waterproof plug.Be provided with ring-shaped groove 3 in the bowl of bowl-shape waterproof plug, ring-shaped groove 3 helps the strain of elastic bottom 1 at bowl wall 4 and at bowl the end 5.The bowl wall 4 of bowl-shape waterproof plug is cylindrical, and the bowl of bowl-shape waterproof plug is oval tabular along 5.
Present embodiment, the thickness of steel disc be about the waterproof plug elastic bottom 1 thickness 1/5th.Steel disc is embedded in the elastic bottom 1 of waterproof plug through in-mould injection.
Steel disc receives contacting by depressing with mainboard switch 7 of keycap support column 6 at side switch waterproof plug.Because existing silica gel material is soft, intensity and poor toughness.If there is not a steel disc, side switch waterproof plug is breaking by depressing easily repeatedly.
The present invention uses the in-mould injection steel disc through silica gel waterproof plug, increases the thick steel disc of 0.1mm in the bottom of water-proof silica-gel plug, has improved the intensity and the useful life of the relevant position of silica gel product greatly.
Foregoing is merely preferred embodiment of the present invention, is not the present invention is carried out the scope restriction.Those skilled in the art can carry out corresponding flexible or modification very easily according to main design of the present invention and spirit.So protection scope of the present invention should be as the criterion with the covering scope of claim.
