なるという問題がある。In the above-mentioned prior art, there is a problem that once the fixing position of the ferrite core mounting portion is determined, the position cannot be easily changed. The reason is that a square hole is provided in the metal surface of the housing for fixing, the cable is tied there through a cable band, or the cable is fixed by a cable clamp. This is because it is necessary to perform a boring process and a cable clamp attaching operation. Also, in the conventional technology, the amount of providing a square hole in the metal surface and the area for attaching the cable clamp,
There is a problem of taking up mounting space. Further, there is a problem in that a cable band is passed through a square hole in the metal housing surface to tie a cable, and a cable clamp is attached to the housing surface and the cable is fixed there, so that the operation becomes complicated.

ことにある。An object of the present invention is to eliminate the above-mentioned disadvantages, to easily change a fixing position of a ferrite core mounting portion on a cable in a metal housing, and to reduce a mounting space of a ferrite core mounting fixed portion. It is another object of the present invention to provide a ferrite core fixing structure that facilitates fixing work.

にフェライトコア装着部分を固定している。In order to solve the above-mentioned problems, in the fixing structure of the present invention, a fixing jig (1 in FIG. 1) used for fixing a ferrite core mounting portion (3 in FIG. 1). Use a permanent magnet for the magnetic metal surface through it (4 in Fig. 1)
The ferrite core mounting part is fixed to

易に取り付けることができる。In such a structure, a ferrite core made of a magnetic material has a property of being attracted to a permanent magnet. In addition, magnetic metals such as iron also adsorb to the permanent magnet.
By utilizing this property, the ferrite core adsorbed and fixed to the permanent magnet can be easily attached to any location on the surface of the magnetic metal housing.

The cable is wound once around the ferrite core 3 which is an unnecessary electromagnetic wave suppressing component. The fixing jig 1 is a permanent magnet, and has a recess 2 so that the ferrite core 3 can be mounted.
Is provided. Since the ferrite core 3 attached to the cable 5 is a magnetic material, it is attracted to the fixing jig 1 which is a permanent magnet, and since the permanent magnet also has a property of adsorbing magnetic metal, the fixing jig 1 which is a permanent magnet Can be attracted to the magnetic metal surface 4 of the housing.

を小さくできるとともに固定作業が極めて簡単になる。As described above, according to the present invention, since the fixing jig can be attached to any magnetic metal surface due to the properties of the permanent magnet, the fixing position can be easily changed.
Also, in the present invention, the only components required for fixing are the fixing jigs that are in close contact with the ferrite core, there is no need to provide square holes on the metal surface, and there is no need to tie with a cable band or fix with a cable clamp. Therefore, the mounting space can be reduced, and the fixing work can be extremely simplified.
