CIRCUITRY AND ELECTRICAL JUNCTION BOX

摘要

PROBLEM TO BE SOLVED: To achieve high-density packaging by relieving the stress applied to a soldered portion of a through hole.SOLUTION: A circuitry includes a conductive plate 20 disposed between a first circuit board 30A and a second circuit board 30B that are disposed facing each other, and a through hole a32 penetrating through the second circuit board 30B. The conductive plate 20 is made of a sheet metal, and includes a planar body 21 and a second bus bar 23 that is extended from the body unit 21 in a curved surface shape and includes an extended edge 23B soldered to the through hole a32. The extended edge 23B of the second bus bar 23 can be displaced relatively to the body unit 21.
