INDUCTOR AND MANUFACTURING METHOD THEREFOR

摘要

An inductor that has the following: an inductor core comprising a plurality of core members arranged in a ring with gaps therebetween; primary insert-molded resin parts comprising a thermoplastic resin covering the outside surface of the inductor core, excluding the surfaces of the core members that face each other; coils disposed around the aforementioned gaps and the primary insert-molded resin parts on the inductor core; and secondary insert-molded resin parts comprising a thermoplastic resin insert-molded around the coils to affix said coils to the inductor core. This allows high-cycle manufacturing of inductors without a thermosetting-resin potting step in a vacuum furnace or a heat curing treatment in a heating furnace.
