REACTOR AND REACTOR-USE COMPONENT
First Claim
1. A reactor including a coil and a core, the coil being formed by helically winding a wire, the core including an internal core portion and a couple core portion, the internal core portion being disposed inside the coil and forming a part of a closed magnetic path, the couple core portion being joined to the internal core portion and forming a remaining part of the closed magnetic path, the reactor being characterized by comprising:
- a resin portion including a region that is interposed between the coil and the internal core portion; and
a cushioning member that is interposed between the resin portion in the region and the internal core portion and that reduces a stress that acts on the resin portion in the region.

Abstract
Provided is a reactor and a reactor component that can prevent cracking of a resin portion that is interposed between a coil and an internal core portion. The reactor includes a coil 10 and a core that includes an internal core portion 22 and a couple core portion 24. The coil 10 is formed by helically winding a wire. The internal core portion 22 is disposed inside the coil and forms a part of a closed magnetic path. The couple core portion 24 is joined to the internal core portion 22 and forms the remaining part of the closed magnetic path. The reactor includes a resin portion (internal resin portion 30) including a region that is interposed between the coil 10 and the internal core portion 22, and a cushioning member 70 that is interposed between the resin portion and the internal core portion 22 and that does not cover the couple core portion 24. It is preferable that the material of the cushioning member 70 has a Young'"'"'s modulus that is smaller than a resin material of the resin portion.

18. A reactor component used for a reactor including a coil and a core, the coil being formed by helically winding a wire, the core including a couple core portion that is disposed not inside the coil and that forms a part of a closed magnetic path, the reactor component being characterized by comprising:
-
an internal core portion that is disposed inside the coil and that forms a remaining part of the closed magnetic path; a cushioning member that covers at least a part of an outer periphery of the internal core portion; and an internal resin portion that integrates the coil with the internal core portion covered by the cushioning member and that retains the shape of the coil. - View Dependent Claims (19)
