Abstract
The utility model discloses a modularized mobile telephone side-key switch, which comprises a contact elastic sheet which is punched with a plurality of elastic pins connected with a circuit board of a mobile telephone, wherein the elastic pins are classified in three types: positive electrode end, negative electrode end and grounding end, and the contact elastic sheet further comprises at least two triggering ends; a shell which is adaptive to the contact elastic sheet and is provided with key through holes on positions corresponding to the triggering ends; and metal domes which covers the key through holes and are used for conducting the corresponding triggering ends during deformation. By the modularized mobile telephone side-key switch, modularization of the side-key switch is realized, and the modularized mobile telephone side-key switch is universal for various mobile telephones; and mobile telephone side keys are free from manual welding, so that the production cost is reduced and the producing efficiency is improved; furthermore, the safety of the mobile telephone under light falling is guaranteed.
Description
Technical field
The utility model relates to handset switch, particularly a kind of modular mobile phone side key switch.
Background technology
At present, side switch commonly used generally has dual mode, and a kind of is to adopt single switch SMT technique to be attached on the mainboard, and the cost compare of this mode switch is expensive, and knocks easily doing drop test, produces bad.Another kind of mode adopts the young sheet of pot to paste on the flexible soft board, it is expensive that but this mode can avoid falling the problem cost that knocks, and want hand weldering, and flexible soft board do little when falling test easily fracture cause badly, every money mobile phone all will customize in the use of reality.
The utility model content
The technical problems to be solved in the utility model is to cause easily the flexible PCB fracture to cause bad defective in order to overcome when mobile phone is little in the prior art falls test, and a kind of modular mobile phone side key switch is provided.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of modular mobile phone side key switch, its characteristics are that it comprises:
One contact flat spring, some shell foots that are connected for the circuit board with a mobile phone that are stamped out on this contact flat spring, described shell foot is divided into positive terminal, negative pole end and earth terminal, and this contact flat spring also comprises at least two trigger ends;
One shell adaptive with this contact flat spring, position corresponding with described trigger end on the described shell is provided with the button through hole; And
Be covered on the described button through hole, be used for the young sheet of pot of described trigger end corresponding to conducting during deformation.
Wherein, this shell is fixed on this contact flat spring by injection mo(u)lding.
Wherein, this shell be coated on this contact flat spring around.
Wherein, this shell is that plastic material is made.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge namely gets each preferred embodiment of the utility model.
Positive progressive effect of the present utility model is: modular mobile phone side key switch of the present utility model has been realized the modularization of side key switch, can realize general at various mobile phones, and this mobile phone side key need not artificial welding, reduced production cost, improved production efficiency, the fail safe in having guaranteed more that mobile phone is little and falling.
Description of drawings
Fig. 1 is the use state diagram of the side key switch in the utility model one preferred embodiment.
Fig. 2 is the explosive view of side key switch among Fig. 1.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As illustrated in fig. 1 and 2, the side key switch 2 in the present embodiment comprises a contact flat spring 22, and it comprises two trigger ends 224.Mode by punching press on contact flat spring 22 stamps out three shell foots, and it is respectively positive terminal 221, negative pole end 222 and earth terminal 223.Around this contact flat spring 22, fix the shell 21 of plastics by the mode of injection moulding.Position corresponding with trigger end 224 on shell 21 is formed with two button through holes 211.This side key switch 2 also comprises the young sheet 23 of pot that is covered on the described button through hole 211, and the young sheet 23 of described pot is made for metal material, and is one and has flexible domes.The direction that arches upward of the young sheet 23 of described pot is pointed to circuit board 1(and is seen Fig. 1) the outside.When the young sheet 23 of pot is pressed then to contact flat spring 22 place side generation deformation, just trigger end 224 corresponding to conducting.After the young sheet 23 of pot was released recovery, trigger end 224 disconnected.In the present embodiment, this shell 21 is fixed by the mode of injection mo(u)lding equally with the young sheet 23 of pot.
During assembling, three shell foots of contact flat spring 22 are connected with the circuit board 1 of mobile phone and get final product.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these execution modes under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection range of the present utility model.
