REACTOR AND METHOD FOR MANUFACTURING THE SAME

WIPO Patent Application WO/2010/067414

A1

A reactor and a method for manufacturing the reactor, in which a process for forming an insulating film around a coil can be eliminated, both vibration at the time of driving a reactor and noise caused by such vibration can be reduced effectively, and thereby a sealing resin body is not cracked easily. The reactor (10) comprises a reactor core (1) consisting of two U-shaped cores (11, 11) having a U-shaped plan view and a gap layer (12) interposed between the U-shaped cores (11, 11), a coil (2) formed in bobbinless posture on the outer circumference of the reactor core (1) while having a gap (G) to the circumferential surface of the reactor core (1), a film resin body (3) formed on the outer circumference of the reactor core (1) and that of the coil (2) and in the gap (G) between the reactor core (1) and the coil (2), and a sealing resin body (4) formed on the outer circumference of the film resin body (3). The film resin body (3) has a relatively low modulus of elasticity as compared with the sealing resin body (4).
