Abstract
The utility model discloses a cell -phone side key structure, including cell phone case, PCB circuit board, dome piece and button, at least one side of PCB circuit board at least some have with the thickness of dome piece looks adaptation, be equipped with the conductive foil on at least one side of PCB circuit board partly at least, the dome piece bonds with the conductive foil, the button is located the outside of dome piece to contact with the dome piece, should press the bond fixation on cell phone case. After adopting above -mentioned technical scheme, can make the narrower cell -phone side key structure of frame width of cell -phone product, and be convenient for assemble, the reliability is high.
Description
Technical field
The utility model relates to the side key structure of mobile phone.
Background technology
The existing back side be the side key structure of the ultra-thin smart handset (thickness is less than 9mm) of large radian as shown in Figure 1, it comprises phone housing 91, the PCB 92 be arranged in the inner chamber of phone housing, fpc(flexible PCB) assembly 93 and button 94.The inwall of phone housing 91 is provided with lateral support muscle 911.Fpc assembly 93 is bonded on brace rod 911, and is electrically connected with the copper-foil conducting electricity of PCB 92.Button 94 is arranged on the side of handset shell 91, and contacts with the dome sheet in fpc assembly.
Phone housing 91 lateral support muscle 911 play supporting role to actuation of keys.At present, market adopts the width L1 of the brace rod 911 of the mobile phone of the side key structure shown in Fig. 1 at least at about 0.5mm, and the width L2 of fpc assembly is greatly about about 0.67mm.
Along with the continuous renewal of mobile phone products, above-mentioned side key structure design has been difficult to meet the demand of consumer to cell phone appearance.When very meticulous to cell phone appearance required precision, often reduce some width, huge leading superiority will be in competition.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of side key structure of cell phone that the border width of mobile phone products can be made narrower, and is convenient to assembling, and reliability is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of side key structure of cell phone, comprises phone housing, PCB, Dome sheet and button; At least one side of PCB there is the thickness at least partially suitable with Dome sheet, at least one side of PCB be provided with conductive foil at least partially, Dome sheet is bonding with conductive foil; Button is positioned at the outside of Dome sheet, and contacts with Dome sheet; This button is fixed on phone housing.
The utility model at least has following technique effect:
1, side key structure of cell phone of the present utility model is compared with existing side key structure of cell phone, owing to not needing to arrange lateral support muscle on handset shell, and do not need the gum in existing fpc assembly and steel disc yet, therefore, it is possible to make the border width of mobile phone products do narrower, outward appearance is also more attractive in appearance, thus satisfies the demands of consumers;
2, Dome sheet of the present utility model is directly pasted onto on pcb board, improves efficiency of assembling;
3, in the technical solution of the utility model, the side of pcb board can provide strong support for the push action of button, therefore, it is possible to increase the pressing life-span of button, improves the reliability of product.
Accompanying drawing explanation
Fig. 1 shows the cross-sectional view of the side key structure of existing a kind of ultra-thin smart handset.
Fig. 2 shows the cross-sectional view of the side key structure according to the utility model one embodiment.
Fig. 3 shows the schematic diagram of PCB according to the utility model one embodiment and Dome sheet.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 2 shows the schematic diagram adopted according to the mobile phone of the side key structure of the utility model one embodiment.Phone housing 1, PCB 2, Dome sheet 3 and button 4 is comprised according to the side key structure of cell phone of the utility model one embodiment.
PCB 2 is arranged in the inner chamber of phone housing 1.At least one side of PCB 2 there is the thickness at least partially suitable with Dome sheet 3, at least one side of PCB 2 be provided with conductive foil at least partially, Dome sheet 3 is bonding with conductive foil.
Button 4 is positioned at the outside of Dome sheet 3, and contacts with Dome sheet 3; This button 4 is fixed on phone housing 1.
Refer to Fig. 3.In the embodiment shown in fig. 3, the part of a side 21 of PCB 2 211 with there is the thickness suitable with Dome sheet 3, and be provided with conductive foil in this part 211, Dome sheet 3 is bonding with conductive foil.Compared with prior art, the utility model adds the thickness at least partially of at least one side of PCB 2, and expose conductive foil on the portion, above Dome sheet 3 can being bonded in, to realize the electrical connection of the main circuit in button and PCB.Increase the mode of PCB thickness, can adopt integrated mode, also can be another block platelet of PCB surface patch at existing thickness.And specifically the thickness of which part of which side of PCB 2 is increased, determine according to the design and installation position of side switch.The said side switch of the application, is not limited to and refers to be arranged on the left of phone housing or the button on right side, also can be mounted in the upside of phone housing or the button of downside.
In a preferred embodiment, the thickness at least partially of at least one side of PCB 2 is 2.5mm ~ 3mm.Dome sheet 3 is bonding with conductive foil by double faced adhesive tape, and this conductive foil is Copper Foil.
The application is not owing to needing to arrange lateral support muscle on phone housing, and do not need the gum in existing fpc assembly and steel disc yet, make the border width of whole mobile phone approximately can reduce 0.9 millimeter, the border width of mobile phone products can not only be made to do narrower, and improve the reliability of efficiency of assembling and product.
