Title: Broad frequency band common mode choke coil
Inventor: SAITO TAKASHI
IPC: H01F37/00
Filed: 1989-09-25
Abstract: PURPOSE:To reduce an installation cost to a substrate by incorporating a 1st dividing closed magnetic circuit core for high frequency into a set of paired divided windings and further, incorporating a 2nd dividing closed magnetic circuit core for low frequency into remaining totally divided windings. CONSTITUTION:A UU type closed magnetic circuit core 5 for low frequency is incorporated into a composite spool 1 with a clamp in such a way as to allow each magnetic leg of the core 5 to pass through the central hole of each square tubiform winding core of principal spool divided stems 2 and 3 and also to abut on each other at the outside of each square tubiform winding core 12. Further, a broad frequency band common mode choke coil (common coil) is obtained by permitting each magnetic leg of a high frequency UU type closed magnetic circuit core 6 to be inserted in the square tubiform winding core 17 of a subsidiary spool 4 and to abut on each other and also by incorporating the core 6 into the subsidiary spool with the clamp. The principal spool divided stems 2 and 3 divide the inside of in-phase into two parts and reduce the distribution capacity of windings to obtain a low frequency common coil in which characteristics of a high frequency band is improved and in this way, high impedance characteristics are secured over a frequency band that is broader than those of both common coils. Further, the composite spool is able to wind windings in a whole winding section by a coil winding machine and magnetic cores for low and high frequencies are incorporated separately. Working steps for mounting to a substrate, in this way, decrease by one-half compared as a two stages mounting step.
