Document Type and Number:
Japanese Patent JP7296047
Kind Code:
B2
Abstract:
A reactor comprising a cylindrically formed coil conductor 1 and a magnetic core 2 containing a magnetic material, wherein the coil conductor 1 and the magnetic core 2 are housed in a case. The coil conductor 1 includes a coil portion 7 having a conductive wire 6 wound thereon, and a first non-magnetic portion 8 formed of a first non-magnetic resin material coating the surface of the coil portion 7. Protruding portions 10a, 10b made of a second non-magnetic resin material are formed on a surface of the first non-magnetic portion 8 at edges of the coil portion 7. The protruding portion 10a is formed in a central direction, indicated by an arrow P, with respect to a winding axis 9 of the coil portion 7. The protruding portion 10b is formed in a centrifugal direction, indicated by an arrow Q, with respect to the winding axis 9 of the coil portion 7. Thus, it is possible to provide a small, high-performance reactor having large inductance which is capable of suppressing generation of eddy current and has a large magnetic flux density with a small magnetic loss.
