よりフェライトコア１．１ａの取付けを行なうようにし
ていた。As mentioned above, the conventional ferrite cores 1 and 1a do not have attachment parts to the chassis of electronic equipment, so as shown in FIGS. 9 and 10, the ferrite cores 1 and 1a are Band-shaped installation aid 3 such as
．． Ferrite core 1.1a with flat cable A or round cable B inserted into insertion hole 2.2a using ferrite core 3a.
For installation, externally fit auxiliary tool 3.3a, and for this installation, auxiliary tool 3.
．． The ferrite core 1.1a was attached by fixing both ends of the ferrite core 3a to the chassis etc. with screws 4.
〈発明が解決しようとする課題〉
