Abstract
Official abstract text for this publication.
A collective conductor includes a plurality of conductive wires that is arranged collectively; and a copper foil that is wound around the collectively-arranged conductive wires and fusion-bonded to the conductive wires, and the copper foil has a tin plating on the side in contact with the conductive wires.
First claim
Opening claim text (preview).
What is claimed is: 1. A collective conductor comprising: a plurality of conductive wires, having a rectangular cross-section, arranged collectively; and a copper foil wound around the collectively-arranged conductive wires and integrated with the conductive wires, wherein: the copper foil has a tin plating on the side in contact with the conductive wires, the copper foil adheres to the conductive wires by fusing the tin plating, the conductive wires have a rectangular cross-section in a direction perpendicular to the longitudinal direction of the conductive wires, and the collective conductor has a bend section that is formed when the collective conductor is bent into a shape of a stator coil, and an overlapping portion where one end of the copper foil overlaps the other end of the copper foil, the overlapping portion being located on the inner periphery side of the bend section. 2. A collective conductor comprising: a plurality of conductive wires, having a rectangular cross-section, arranged collectively; and a copper foil wound around the collectively-arranged conductive wires and integrated with the conductive wires, wherein: the copper foil has a tin plating on the side in contact with the conductive wires, the copper foil adheres to the conductive wires by fusing the tin plating, the conductive wires have a rectangular cross-section in a direction perpendicular to the longitudinal direction of the conductive wires, and the collective conductor has a bend section, and the copper foil on the inner periphery side of the bend section is thicker than the copper foil on the outer periphery side of the bend section.
