Embodiment

It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer Each embodiment of type is explained in detail.It is however, it will be understood by those skilled in the art that each in the utility model In embodiment, in order that reader more fully understands the application and proposes many ins and outs.But even if without these skills Art details and many variations based on following embodiment and modification, the application technical side claimed can also be realized Case.

First embodiment of the present utility model is related to a kind of mobile communication terminal.As Figure 1-3, mobile communication terminal 10 include：Housing 11, mainboard 12, an at least side switch 13, flexible PCB 14 and battery cover 15, mainboard 12 are arranged on housing 11 In, side switch 13 is connected by flexible PCB 14 with mainboard 12, and battery cover 15 is covered on housing 11, and side switch 13 is arranged on electricity On pond lid 15, mobile communication terminal 10 also includes support chip 16, and support chip 16 is fixed on battery cover 15, flexible PCB 14 It is fixed on battery cover 15 by support chip 16, and is equipped with side switch 13.

In the utility model embodiment, side switch 13 and flexible PCB 14 are all disposed within battery cover 15, relative position Fixed, the fit tolerance between by housing 11 and battery cover 15 is not influenceed, simple in construction, easy for installation, maintenance facility, can Reduce maintenance cost.

In the utility model embodiment, referring to Fig. 3, battery cover 15 includes battery cover body 151 and side 152, side Key 13 is arranged on side 152, and support chip 16 is fixed on battery cover body 151.Battery cover body 151 hangs down to inside housing 11 Straight extension forms a barricade 153, and support chip 16 is fixed on barricade 153.

Fixing groove 17 is provided with housing 11, when battery cover 15 covers with housing 11, support chip 16 and barricade 153 are fixed In fixing groove 17.

Flexible PCB 14 includes fixing end 141 and contact jaw 142, fixing end 141 be fixed on support chip 16 away from gear In the one side of wall 153, and along the bottom of fixing groove 17 and extend sideways, contact jaw 142 is fixed on battery cover body 151.Branch One end of the close battery cover body 151 of blade 16 extends vertically to form a step 161 to battery cover side 152, fix 141 with Step 161, which contradicts, to be fixed.

As Figure 2-3, mainboard 12 with the contact position of flexible PCB 14 be provided with shell fragment or play pin 121, flexible circuit The contact jaw 142 of plate 14 is contacted by shell fragment or bullet pin 121 with mainboard 12.The contact jaw 142 of flexible PCB 14 uses golden hand The form of finger contacts with mainboard 12.Specifically, multiple conductive contact blades 143, multiple conductive contact blades are provided with contact jaw 142 143 contact with shell fragment or bullet pin 121, and then the contact jaw 142 of flexible PCB 14 is contacted with mainboard 12.It is so that flexible The feed point flexibility in position of circuit board 14 is big, and mainboard 12 can Anywhere be realized in theory.
