For example, in the example of FIG. 19 and FIG. 20 , the welding section 422 extends from the extension section 421 in a direction parallel to the thickness direction of the extension section 421 toward the inside of the interface 100, that is, first extends in the left-right direction, and then bends along a direction perpendicular to the extension. The section 421 extends in the thickness direction, that is, extends along the front-to-back direction, thereby not only reducing the width of the interface 100 further, but also facilitating the welding of the welding section 422 and the circuit board 7 .

Specifically, as shown in FIG. 18 and FIG. 20 , the welding section 422 bends and extends in an arc. Thus, the sharp corners of the welding section 422 can be reduced, the stress concentration phenomenon of the welding section 422 can be reduced, and the structural strength of the welding section 422 can be improved, thereby improving the reliability of the connection between the fixed metal sheet 4 and the circuit board 7 .

In addition, as shown in FIGS. 18-20 , an arc-shaped transition section 423 is provided between the welding section 422 and the extension section 421 . Thus, the phenomenon of stress concentration between the extension section 421 and the welding section 422 due to stress can be avoided, the reliability of the connection between the extension section 421 and the welding section 422 can be enhanced, thereby enhancing the structural strength of the fixed metal sheet 4, Furthermore, the reliability of the connection between the fixed metal sheet 4 and the circuit board 7 is improved.

In some embodiments of the present invention, as shown in FIGS. 18-21 , there are two reinforcing welding legs 42 . Therefore, not only the reliability of the connection between the fixed metal sheet 4 and the circuit board 7 can be enhanced, but also the structure and processing technology of the fixed metal sheet 4 can be simplified, the production cycle can be saved, and the production cost can be reduced. Of course, the present invention is not limited thereto, and there may be multiple fixing pieces 11 , and multiple fixing metal pieces 4 may be distributed at intervals along the lower end surface of the fixing metal pieces 4 .

Specifically, as shown in FIGS. 18-20 , the welding sections 422 of the two reinforcing welding legs 42 extend toward each other and then bend and extend away from the extension section 421 . This not only facilitates the welding between the reinforced soldering legs 42 and the circuit board 7, but also reduces the distance between the two reinforced soldering legs 42 when the welding sections 422 of the two reinforced soldering legs 42 first extend toward each other. , so that the width of the interface 100 can be reduced, and the occupied space of the interface 1001 can be reduced.

In some embodiments of the present invention, the extension section 421 and the welding section 422 are integrally formed. In this way, the assembling process of the reinforcing welding leg 42 can be simplified, thereby simplifying the assembling process of the reinforcing welding leg 42 , saving the production cycle and reducing the production cost. When processing the reinforcing welding leg 42 , the extension section 421 and the welding section 422 can be processed into an integrated structure, which can save time spent on assembling between the extension section 421 and the welding section 422 during assembly.

Optionally, the reinforcing welding leg 42 and the fixing metal sheet 4 are integrally formed parts. Thus, not only the assembly process between the extension section 421 and the welding section 422 can be saved, but also the assembly process between the extension section 421 and the fixed metal sheet 4 can be simplified, thereby further simplifying the assembly process of the fixed metal sheet 4 and further saving production. cycle and reduce production costs.
