Abstract
Provided is a reactor in which a resin is sufficiently filled into winding portions. The reactor includes a coil having a first winding portion and a second winding portion and a magnetic core having an inner core portion and an outer core portion. The outer core portion includes a first groove portion and a second groove portion that are open to a coil facing surface opposite to the coil. When viewed from the axial direction of the first winding portion, the opening of the first groove portion is located at a first region between the outer circumferential contour of the first winding portion and the outer circumferential contour of the inner core portion that is disposed inside of the first winding portion. The inner resin portion and the outer resin portion are connected via the first groove portion and the second groove portion.
Claims9
A reactor comprising:
- a coil that has a first winding portion and a second winding portion;
- a magnetic core that has inner core portions, which are respectively disposed inside of the first winding portion and the second winding portion, and outer core portions that form an annular magnetic path with the inner core portions;
- an inner resin portion that covers at least a part of the inner core portion;
- and
- an outer resin portion that covers at least a part of the outer core portion,
- wherein, the outer core portion includes a first groove portion and a second groove portion that are open to a coil facing surface opposite to the coil,
- when viewed from the axial direction of the first winding portion, an opening of the first groove portion is located between the outer circumferential contour of the first winding portion and the outer circumferential contour of the inner core portion that is disposed inside of the first winding portion,
- when viewed from the axial direction of the second winding portion, an opening of the second groove portion is located between the outer circumferential contour of the second winding portion and the outer circumferential contour of the inner core portion that is disposed inside of the second winding portion, and
- the inner resin portion and the outer resin portion are connected via the first groove portion and the second groove portion.
