Specific embodiment
For the ease of the understanding of those skilled in the art, the utility model is made below in conjunction with the drawings and specific embodiments into
One step is described in detail.
A kind of golden finger of the local narrowed structure of band is provided, as shown in Figs. 1-2, the golden finger is T fonts, the gold hand
The both sides for referring to upper end are connect with circuit board, and the lower end of the golden finger is hanging.The golden finger corner is located on vertical direction
It inwardly narrows side.
Positive vertical direction is equipped with front-side circuit 10 on the golden finger, on the front-side circuit 10 from the top down according to
Secondary to be equipped with first through hole 4 and elongated slot 3, the elongated slot 3 is located at the narrowed place of the golden finger；The back side of the golden finger it is vertical
Direction is equipped with the first back-side circuit 20, and the horizontal direction at the back side of the golden finger is equipped with the second back-side circuit 21, described
21 mutually insulated of first back-side circuit 20 and the second back-side circuit；The front-side circuit 10 passes through 4 and second back side of first through hole
Circuit 21 connects, and the front-side circuit 10 is connect by elongated slot 3 with the first back-side circuit 20.
The front-side circuit 10 includes the front cathode circuit and front cathode traces of two mutually insulateds；First back of the body
Face circuit 20 includes the first cathode circuit and the first cathode traces of two mutually insulateds；Second back-side circuit 21 includes two
The second cathode circuit and the second cathode traces of mutually insulated；The front cathode circuit respectively with the first cathode circuit and
Two cathode circuits connect, and the front cathode traces are connect respectively with the first cathode traces and the second cathode traces.
One end that the front cathode circuit and front cathode traces are located at the golden finger free end is equipped with front the
