Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Embodiment mono-:
The present embodiment has proposed a kind of camera module, as shown in Fig. 2 to 5, this camera module comprises lens bracket 1, is installed on the flexible circuit board 2 of lens bracket 1 rear end, is installed on the voice coil motor 3 of lens bracket 1 front end and is installed on the camera lens 5 in lens bracket 1.Connector 4 for being connected with electronic equipment components and parts is installed on the side away from lens bracket 1 end in flexible circuit board 2, on another side, is provided with the first reinforcing chip 6, the first reinforcing chips 6 for ground connection and strengthens signal.When flexible PCB 2 vertically arranges, the lower limb of the first reinforcing chip 6 is concordant with the edge of flexible circuit board 2, and other end is higher than the top edge of connector 4.By the first reinforcing chip 6 is set, can effectively prevent that flexible circuit board 2 from fractureing herein, improve the structural strength of flexible circuit board 2, meanwhile, the first reinforcing chip 6 adopts steel disc, can also play the effect of ground connection and enhancing signal.
