Abstract
A method of manufacturing a rectangular conducting wire wherein insulating coating of rectangular conducting wire is removed by applying laser light the insulating coating, four planar portions on exterior of rectangular conducting wire are sequentially defined as a first, second, third, and fourth face portion, second corner portion is defined between second and third face portions, and fourth corner portion is defined between fourth and first face portions.
Claims17
A method of manufacturing a rectangular conducting wire in which an insulating coating of the rectangular conducting wire is removed by applying laser light to the insulating coating, wherein
- four planar portions on an exterior of the rectangular conducting wire are defined in adjacent order of arrangement as a first face portion, a second face portion, a third face portion, and a fourth face portion,
- a corner portion between the first face portion and the second face portion is defined as a first corner portion,
- a corner portion between the second face portion and the third face portion is defined as a second corner portion,
- a corner portion between the third face portion and the fourth face portion is defined as a third corner portion, and
- a corner portion between the fourth face portion and the first face portion is defined as a fourth corner portion, the method comprising:
- a first step of applying the laser light to a first area including the first face portion, the first corner portion, and the second face portion, with the rectangular conducting wire placed in a first position where the first face portion and the second face portion face an application unit for applying the laser light, where an angle formed at an intersection point of a straight line parallel to an optical axis of the laser light with the first face portion toward the fourth corner portion is an obtuse angle, and where an angle formed at an intersection point of a straight line parallel to the optical axis with the second face portion toward the second corner portion is an obtuse angle.
