REACTOR AND MANUFACTURING METHOD THEREOF

摘要

A reactor comprises a reactor core in which two U-shaped core members are connected in a ring shape with a gap section therebetween, a primary insert-molded resin part provided covering at least an outer peripheral surface of a leg part of the core member other than an adhesion surface of the core member, a coil placed around the gap section and the leg part of the core member, and a secondary insert-molded resin part made of a thermoplastic resin and which is insert-molded around the coil to fix the coil on the reactor core and fix the leg parts of the core members in a connected state. A positioning section which determines a relative position of opposing leg parts and a window section which allows a melted thermoplastic resin for forming the secondary insert-molded resin part to flow into the gap section are formed on an end of the primary insert-molded resin part connected in a state where core members are placed connected in a ring shape.

1. A reactor comprising:
a reactor core in which two U-shaped core members are connected in a ring shape with a gap section therebetween; a primary insert-molded resin part which is provided covering at least an outer peripheral surface of a leg part of the core member other than an adhesion surface of the core member; a coil which is placed around the gap section and the leg part of the core member; and a secondary insert-molded resin part which is made of a thermoplastic resin and which is insert-molded around the coil to fix the coil on the reactor core and fix the leg parts of the two core members in a connected state, wherein a positioning section which determines a relative position of opposed leg parts and a window section which allows a melted thermoplastic resin for forming the secondary insert-molded resin part to flow into the gap section are formed on ends of the primary insert-molded resin part connected to each other in a state in which the core members are placed connected in a ring shape.
