Induction Device

摘要

A method of producing an induction device includes the steps of a forming a coil and core assembly, forming rectangular holes, and press-fitting a second core. An induction device includes a first core, a coil wound around the first core, and a second core cooperating with the first core to form a closed magnetic circuit. The first core and the coil are molded by a mold resin to form a molding, and the second core is assembled to the molding.

1. A method of producing an induction device, comprising the steps of:
forming a coil and core assembly by integrally molding said coil and a first core by a mold resin adapted to hold the first core in position radially inward of said coil; forming a rectangular hole in said coil and core assembly adapted for mounting a second core; and press-fitting said second core into the rectangular hole of the coil and core assembly so as to provide a gap between the first core and the second core.
