Title:
REACTOR AND METHOD OF MANUFACTURE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2011/118507
Kind Code:
A1
Abstract:
Disclosed is a method of manufacture for a reactor wherein a core is injection moulded from a compound material comprising a soft magnetic powder and a thermoplastic resin, and a coil is embedded thereinto and integrated therewith. The method provides an excellent injection moulding technique for forming a core wherein the coil is effectively prevented from moving or deforming when the core is formed. A reactor (15) is manufactured by: a step A wherein a coil enclosure (24) is formed by enclosing a coil (10), made by winding a wire rod while an insulating layer is interposed therebetween, in an electrically insulating resin; and a stage wherein the core (16) is formed by injection moulding the compound material comprising a soft magnetic powder and a thermoplastic resin so as to encapsulate the coil enclosure (24). Further, injection moulding of the core (16) is divided into: a stage wherein a first body (16-1) which makes up the vessel shape is formed separately; and a stage wherein a second body (16-2) is formed while the coil enclosure (24) is positioned inside the first body (16-1).
