Document Type and Number:
WIPO Patent Application WO/2016/129487
Kind Code:
A1
Abstract:
Provided is a reactor core piece having excellent bondability with a resin mold portion. The reactor core piece comprises a compacted powder formed body obtained by pressing and forming raw material powder containing soft magnetic powder, the reactor core piece forming a part of a magnetic core disposed inside and outside a reactor coil, wherein the reactor core piece is provided with a plurality of shallow-bottomed grooves extending parallel to one another on at least one surface of the compacted powder formed body. The reactor core piece is configured such that, when a resin mold portion is formed on a surface thereof, the resin mold portion can be made to penetrate into the shallow-bottomed grooves. As a result, the contact area between the reactor core piece and the resin mold portion is increased compared with conventional art, providing the reactor core piece with excellent bondability with the resin mold portion.
