Abstract
(EN) The present invention addresses the problem of increasing the cross sectional surface area of a bent portion. A coil (1) is provided with a wound conducting wire (2). The conducting wire (2) includes: bent portions (C0) that have been subjected to a bending process; and a plurality of side portions (S0) which are positioned on both sides of the bent portions (C0) in the direction in which the conducting wire (2) extends, and which have a smaller curvature than the bent portions (C0). A width (Wi1) from the inner periphery to the outer periphery of the conducting wire (2) in the bent portions (C0) is at least equal to a width (Wi2) from the inner periphery to the outer periphery of the conducting wire (2) in the plurality of side portions (S0).
(FR) La présente invention aborde le problème de l'augmentation de la surface de section transversale d'une partie cintrée. Une bobine (1) est pourvue d'un fil conducteur enroulé (2). Le fil conducteur (2) comprend : des parties cintrées (C0) qui ont été soumises à un processus de cintrage ; et une pluralité de parties latérales (S0) qui sont positionnées sur les deux côtés des parties cintrées (C0) dans la direction dans laquelle s'étend le fil conducteur (2), et qui ont une courbure inférieure à celle des parties cintrées (C0). Une largeur (Wi1) de la périphérie interne à la périphérie externe du fil conducteur (2) dans les parties cintrées (C0) est supérieure ou égale à une largeur (Wi2) de la périphérie interne à la périphérie externe du fil conducteur (2) dans la pluralité de parties latérales (S0).
(JA) 本開示の課題は、屈曲部における横断面の面積を大きくすることである。コイル(1)は、巻回された導線(2)を備える。導線(2)は、曲げ加工された屈曲部(C0)と、導線(2)の延伸方向において屈曲部(C0)の両側に位置し、屈曲部(C0)と比べて曲率が小さい複数の辺部(S0)とを有する。屈曲部(C0)における導線(2)の内周から外周までの幅(Wi1)は、複数の辺部(S0)における導線(2)の内周から外周までの幅(Wi2)以上である。
