Abstract:
(EN) Provided is a reactor equipped with a coil having wound portions and a magnetic core comprising core segments which each have an inner core portion disposed on the inner side of a wound portion, wherein the core segments are molded bodies of a composite material comprising a magnetic powder and a resin, and are each provided with a first protrusion that is integrally formed protruding from the outer peripheral surface of the inner core portion and that positions the wound portion in the radial direction by contacting the inner peripheral surface of the wound portion, and a second protrusion that is integrally formed protruding from the core segment in a position facing the end face of the wound portion and that positions the wound portion in the axial direction by contacting the end face of the wound portion.
(FR) L'invention concerne un réacteur équipé d'une bobine ayant des parties enroulées et d'un noyau magnétique comprenant des segments de noyau qui ont chacun une partie de noyau interne disposée sur le côté interne d'une partie enroulée, les segments de noyau étant des corps moulés d'un matériau composite comprenant une poudre magnétique et une résine, et étant chacun dotés d'une première saillie qui fait saillie d'un seul tenant à partir de la surface périphérique externe de la partie de noyau interne et qui positionne la partie enroulée dans la direction radiale en mettant en contact la surface périphérique interne de la partie enroulée, et d'une seconde saillie qui fait saillie d'un seul tenant à partir du segment de noyau dans une position faisant face à la face d'extrémité de la partie enroulée et qui positionne la partie enroulée dans la direction axiale en mettant en contact la face d'extrémité de la partie enroulée.
(JA) 巻回部を有するコイルと、前記巻回部の内側に配置される内側コア部を有するコア片を含む磁性コアと、を備えるリアクトルであって、前記コア片が磁性粉末と樹脂とを含む複合材料の成形体であり、前記内側コア部の外周面から突出して一体成形され、前記巻回部の内周面に接して前記巻回部の径方向を位置決めする第1突起と、前記コア片から突出して前記巻回部の端面に対向する位置に一体成形され、前記巻回部の端面に接して前記巻回部の軸方向を位置決めする第2突起と、を備えるリアクトル。
