According to the position of the positioning part 111 on the column mold 110, the corresponding positioning connection hole 322 is arranged on the flexible board, so that when the flexible board is wrapped on the outer side wall of the column mold 110, the positioning connection hole 322 is sleeved at the positioning part 111.
Specifically, the circuit board 312 and the film 311 have positioning connection holes 322 at corresponding positions, respectively, and when the film 311 is glued on the surface of the circuit board 312, the positioning connection holes 322 of the two correspond in position.
