JPWO2011118508A1 被覆コイル成形体の製造方法及び被覆コイル成形体 审中-公开

被覆コイル成形体の製造方法及び被覆コイル成形体
Abstract:
【課題】コイルを電気絶縁性の樹脂にて包み込む状態に被覆して成る被覆コイル成形体を容易に製造でき、且つその際にコイルの位置ずれや変形を良好に防止し得る被覆コイル成形体の製造方法を提供する。【解決手段】コイル10を被覆する樹脂被覆層を熱可塑性樹脂にて射出成形するようにし、且つ射出成形の工程を、コイル10の内周面に1次成形型を接触させてコイル10を径方向に位置決めし拘束した状態で、外周被覆部46を含む1次成形体22-1を成形する1次成形工程と、しかる後1次成形体22-1をコイル10とともに2次成形型にセットして、内周被覆部を含む2次成形体を成形する2次成形工程とに分けて射出成形するようになす。【選択図】図5
Abstract(English):

A coil can be easily producing coated coil molded body formed by coating in a state of enveloping by an electric insulating resin, and coating the coil molded can favorably prevent displacement or deformation of the coil during its to provide a process for the production.
The A resin coating layer covering the coil 10 so as to injection-molding of a thermoplastic resin, and the injection molding process, the diameter of the coil 10 by contacting the primary mold to the inner peripheral surface of the coil 10 in a state of being restrained positioned in the direction, set a primary molding step for molding the primary molded body 22-1, the whereafter primary molded body 22-1 together with the coil 10 to the secondary molding mold comprising an outer cover portion 46 and, as to the injection molding is divided into a secondary molding step of molding the secondary molded body including the inner circumferential covering portion eggplant.
