摘要： A reactor includes a coil formed by winding a wire, and a magnetic core in which a closed magnetic path is formed by both an inner core portion inserted in the coil and an outer core portion covering outer peripheral surfaces of the inner core portion and the coil. The outer core portion is formed of a mixture containing a magnetic material and resin. One of the coil and the inner core portion has an exposed portion where a part of the outer peripheral surface is not covered with the outer core portion, and at least a part of the exposed portion is in contact with a heat dissipation layer provided in a heat dissipation plate.

摘要： To provide a reactor whose number of components is small and that exhibits excellent assemblability. A reactor 1 includes a coil 2 having a pair of coil elements 2a and 2b, and a core unit 3 having a pair of intermediate core portions 30 around which the coil elements 2a and 2b are respectively disposed. The core unit 3 is formed to be annular by a combination of intermediate core pieces 31 that structure intermediate core portions 30, a pair of end core pieces 32 that clamps a pair of intermediate core portions 30 disposed in parallel to each other, and gap members 3g each disposed between each ones of the core pieces. The end core pieces 32 respectively include clamping faces 321 for clamping the intermediate core portions 30, each structured with a single plane. An installed face 320l of each of the end core pieces 32 projects further than the installed face 31l of the intermediate core pieces 31. One gap member 3g is interposed between the end core piece 32 and the intermediate core portion 30, and relative permeability of the gap member 3g is greater than 1. This structure simplifies the shape of the core pieces, and allows the number of components to be small despite the core unit 3 partially projects.

摘要： A reactor-use component which provides improved workability in assembling into a reactor, and a reactor using the component are provided. The reactor-use component is for structuring a reactor including a coil 10 formed with a pair of paralleled coil elements 10A and 10B made of a spirally wound wire and a core 20 fitted into the coil elements 10A and 10B to form an annular shape. The reactor-use component includes an internal resin portion 30 that retains a shape of the coil 10, and hollow bores 30h formed by a part of the internal resin portion 30 for fitting the core 20 to inner circumferences of the coil elements 10A and 10B. By inserting internal core portions 22 into the hollow bores 30h and joining opposite ends of the internal core portions 22 to exposed core portions 24, the reactor 1 can be obtained. Because the internal resin portion 30 retains the coil 10 in a state incapable of expanding or compressing, the workability in assembling into the reactor 1 can be improved.
