The third strip section The segment 1361 is used for electrical connection with the second interface part 143 .

It can be understood that the shape defined by the third connecting segment and the fourth bar segment 1362 is determined by the shape of the second connecting segment 1363 , for example, the second connecting segment 1363 is a bar extending along the length direction of the subframe 110 section, the second connecting section 1363 and the fourth strip section 1362 are perpendicular. Alternatively, the second connecting section 1363 is a strip structure and the second connecting section 1363 is inclined to the fourth strip section 1362 .
