REACTOR AND MANUFACTURING METHOD THEREOF
A reactor may include: a ring core having a ring shape; a resin cover covering the ring core with a space left on an inner side relative to the ring core; and a columnar core around which a winding is wound. The columnar core may be fixed to the resin cover in a state where each of ends of the columnar core is opposed to an inner surface of the ring core.
1 . A reactor comprising:
a ring core having a ring shape;
a resin cover covering the ring core with a space left on an inner side of the ring core; and
a columnar core around which a winding is wound,
wherein
the columnar core is fixed to the resin cover in a state where each of ends of the columnar core is opposed to an inner surface of the ring core.
2 . The reactor of claim 1 , wherein the resin cover comprises a positioning guide that contacts with one of the ends of the columnar core.
3 . The reactor of claim 2 , wherein the positioning guide is a protrusion protruding from an inner surface of the resin cover.
4 . The reactor of claim 1 , wherein the resin cover comprises a fixing portion which fixes a cooler.
5 . The reactor of claim 1 , wherein a gap between the resin cover and the winding is filled with a potting material.
6 . A manufacturing method of the reactor according to claim 5 , the method comprising:
fixing the columnar core around which the winding is wound to the resin cover covering the ring core; and
filling the gap between the resin cover and the winding with the potting material.
