Position column 31, positioning hole number is identical as positioning column quantity, so set, making key frame 1 and key component 2 before being installed on
It is more convenient, accurate to align when shell 3.In more detail, two positioning columns 31 and phase in a pair of of linea angulata in four positioning columns 31
The clearance D 1 of the hole wall of the location hole 13 of cooperation is 0.05mm.It is appreciated that multiple positioning columns 31 positioned at 3 four corners of front housing
Setting can be improved pairing precision, and two positioning columns 31 in a pair of of linea angulata and the hole wall of the location hole 13 matched
Clearance D 1 is 0.05mm, then makes key frame 1 and front housing 3 precisely, and two positioning columns 31 are in a pair of of linea angulata, avoid by
It rotates between key frame 1 and front housing 3, guarantees the stability of installation effect.
Further, Fig. 2, Fig. 4, Fig. 5 and Fig. 6 are please referred to, is determined in four positioning columns 31 in another cornerwise two
Position column 31 is 0.3mm with the clearance D 2 of the hole wall of the location hole 13 matched.It can be appreciated that if four positioning columns 31 with match
The gap of hole wall of location hole 13 be all provided with and be set to 0.05mm, then make key frame 1 and front housing 3 that cooperation tension is installed, it is inconvenient
In the installation and the disassembly in later period of early period, therefore it is in the hole of another cornerwise two positioning columns 31 and the location hole 13 matched
The clearance D 2 of wall is 0.3mm, realizes the effect that key frame 1 and 3 pine of front housing are matched.
Next the material of key frame 1 Yu key component 2 will be introduced, key frame 1 uses ebonite material, key component
2 use soft rubber material.In the present embodiment, key frame 1 uses ABS plastic, it is of course also possible to be moulded using PS plastic, AS
Other ebonite materials such as material and hard PVC；And key component 2 is also possible to adopt using flexible glue TPU in other embodiments
With other soft rubber materials such as flexible glue PVC, silica gel.So set, transport key frame 1 will not during key 21 presses
Dynamic, extruding is key set 22 and key 21, the case where key 21 scrapes front housing 3 is avoided, to avoid 21 card key of key
Problem.In addition, key component 2 uses soft rubber material, so that key 21 exerts a force to it pressing convenient for operator, meanwhile, key
Component 2 also improves feel using soft rubber material.
Produce in enormous quantities in order to realize, key frame 1 and the key component 2 use dijection injection molding process.
It is appreciated that being separately formed ebonite and flexible glue part in two mold cavities, key frame 1 and key after processing not can guarantee
The cooperation precision of component 2, causes the scrappage of product relatively high, and dijection injection molding process forms firmly in a mold cavity
Glue and flexible glue, ensure that machining accuracy, may be implemented to produce in enormous quantities, while also simplifying production mould, reduce and be produced into
This.
Further, referring to FIG. 2, key device further includes microphone circuit plate 5, microphone circuit plate 5 is set to institute
It states between front housing 3 and the key frame 1, corresponding 2 position of key component of microphone circuit plate 5 is offered for the key
The relief hole 51 that component 2 passes through.So set, enhancing the function of key device, allow to answer voice.
In order to avoid front housing 3 is damaged to 5 surface of microphone circuit plate, silicon is provided between microphone circuit plate 5 and front housing 3
Rubber gasket 6.It is appreciated that during the installation process, silicone gasket 6 has buffer function, avoids front housing 3 and directly compress microphone
5 surface of circuit board has protective effect to 5 surface of microphone circuit plate.It should be noted that the application is without being limited thereto, Yu Qi
In his embodiment, it is also possible to using rubber washer or other flexible materials.
The present invention also proposes a kind of electronic product, which includes key device and pcb board 4, the key device
Specific structure is referring to above-described embodiment, since electronic product uses whole technical solutions of above-mentioned all embodiments, until
