Installation structure null of core and its core for electromagnetics shield

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic shielding core mounting structure capable of increasing permeability and preventing release of a core main body further laminated without developing crack or defects on the core body and facilitating mounting or de-mounting work to a core mounted body. ;SOLUTION: A core body 18 formed by laminating a soft magnetic film 18a and an insulation film 18b alternately and adhering them is disposed crossing a magnetic flux generation coil 14 of an electromagnetic inductive heating device, and this core body 18 is covered with a non-conductive element 19. The non-conductive element 19 is formed of resin or rubber, and a soft magnetic film 18a is formed of ion-based amorphous, cobalt-based amorphous, or silicon steel. Further, the electromagnetic shielding core 17 is screwed with the magnetic flux generation coil 14 sandwiched on a lower face of an outer jar 12 to which the magnetic flux generation coil 14 of the electromagnetic inductive heating device is attached.;COPYRIGHT: (C)1998,JPO
