REACTOR

摘要

Provided is a reactor exhibiting stable magnetic characteristics. The reactor includes a coil, a magnetic core having an inner core portion and an outer core, and an end surface connecting member disposed between an end surface of the winding portion and the outer core portion. The reactor includes a resin-molded portion integrates integrating the outer core portion and the end surface connecting member, and a plurality of protruding portions provided disposed on an outer surface of the end surface connecting member on which the outer core portion is disposed and that supports the outer core portion at a distance from the outer surface, the resin-molded portion enters a gap formed between the outer surface and the outer core portion by the protruding portions, thereby forming a resin gap between the inner core portion and the outer core portion are being separated from each other by the end surface connecting member.

主权项

1. A reactor comprising:
a coil having a winding portion; a magnetic core having an inner core portion disposed inside the winding portion and an outer core portion disposed outside the winding portion; an end surface connecting member that is disposed between an end surface of the winding portion and the outer core portion; a resin-molded portion that integrates the outer core portion and the end surface connecting member; and a plurality of protruding portions that are provided on an outer surface of the end surface connecting member on which the outer core portion is disposed and that support the outer core portion at a distance from the outer surface, wherein the resin-molded portion enters a gap that is formed between the outer surface and the outer core portion by the protruding portions, thereby forming a resin gap between the inner core portion and the outer core portion that are separated from each other by the end surface connecting member.
