Title:
REACTOR
Document Type and Number:
Japanese Patent JP2020072120
Kind Code:
A
Abstract:
To provide a compact reactor that hardly causes magnetic saturation.SOLUTION: A reactor includes: a coil including two wound sections and a coupling section coupling both wound sections; magnetic cores including inner core sections disposed inside the respective magnetic cores and outer core sections disposed outside; and a resin mold section covering at least part of the outer peripheral surface of the magnetic cores. At least one of both outer core sections includes a composite core in which a molded body of a composite material and a powder compressed molded body are laminated in a height direction, where the height direction is assumed to be a direction orthogonal to the axial direction of the wound sections and an aligned direction of both wound sections. The coupling section protrudes outward in the axial direction from an end of the inner core section on one end side of the axial direction of both wound sections. The composite core is disposed on one end side in the axial direction of both wound sections, has a place that protrudes upward in the height direction from the outer peripheral surface of the inner core section, and includes a first composite core in which the molded body of the composite material is laminated on the upper side in the height direction and the powder compressed molded body is laminated on the lower side. The resin mold section includes a first outer resin section covering the first composite core.SELECTED DRAWING: Figure 1
