【Detailed ways】

The specific implementation of the electrical connector of the present invention will be described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 to FIG. 3 , the electrical connector 1 of the present invention electrically connects the camera module 7 to an external circuit board (not shown) through a flexible circuit board 9 , and includes a metal shell 10 and an elastic terminal 30 .

The metal shell 10 is integrally formed by stamping and bending a plate-shaped metal plate, including a bottom wall 101 and a side wall (not marked), wherein the side wall is composed of a front wall 103, a rear wall 105, a left wall 109 and a right wall 107 . The bottom wall 101, the front wall 103, the rear wall 105, the left wall 109 and the right wall 107 jointly form a storage space 100 to accommodate the camera module 7, and the right wall 107 and the left wall 109 are identical in structure, and the middle position of the left wall 109 is provided with a A window 1090 is used for the penetration of the flexible circuit board 9 , and the middle position of the top of the right wall 107 is recessed downwards to form a notch 1070 for the convenience of taking and placing the camera module 7 . Wherein, the position of the above-mentioned notch 1070 is opposite to the position of the window 1090. The difference is that the notch 1070 is slightly recessed from the top edge of the right wall 107 downwards, while the window 1090 runs through the top of the left wall 109 to the bottom. .
