Document Type and Number:
WIPO Patent Application WO/2011/013607
Kind Code:
A1
Abstract:
Provided are a reactor and reactor-use components that restrict the occurrence of cracks in the resin portion situated between a coil and an inner-side core part. The reactor has a coil (10) made of winding wire wound around in a spiral shape, an inner-side core part (22) consisting of part of a closed magnetic circuit and installed inside the coil, and a connected core part (24) consisting of the remaining part of the closed magnetic circuit and which is joined to the inner-side core part (22). This reactor 1 is equipped with a resin portion (internal resin portion 30), situated in the area between the coil (10) and the inner-side core part (22), and a buffer part (70) which is located between the resin part and inner-side core part (22) and which does not cover the connected core part (24). It is preferable if the material that the buffer part (70) consists of has a smaller Young's modulus than the resin that makes up the resin part.
