Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案はチョークコイル、トランスなどの磁気部品から
漏洩する磁束によって生ずるノイズに対する磁気シール
ドケースに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a magnetic shield case against noise generated by magnetic flux leaking from magnetic components such as choke coils and transformers.
従来のケース作成方法は、例えばドーナツ形のコアに捲
回されたコイルの例で述べると、第５図の如く、正八角
形の底面（カバー上部に相当）12の各陵にコイルの厚み
分が十分入いる高さＨなる側辺11を設け、これを点線Ｃ
部から折曲げると一方が開口部となった正八角柱のカバ
ーが作成出来る。これは、四角形、六角形などでもよ
い。In the conventional case making method, for example, in the case of a coil wound around a donut-shaped core, as shown in FIG. 5, each coil of the regular octagonal bottom surface (corresponding to the upper portion of the cover) 12 has a thickness of the coil. Provide a side 11 with a height H that is sufficiently large, and attach this to the dotted line C
If you bend it from one part, you can create a regular octagonal prism cover with one side as an opening. It may be square, hexagonal, etc.
又図示していないが、円柱状に成形加工した例もある。Although not shown, there is also an example of forming into a cylindrical shape.
上記の従来例では、側辺11を折り曲げる為に特別の曲げ
型が必要となり、又、側面部が切れているため、磁気的
に抵抗分が大きい構造となっている。又、円柱状に成形
する方法では、絞り型が必要となる。又、これらの例で
はコイルのサイズ毎に成形、絞り型が必要となる。In the above-mentioned conventional example, a special bending die is required to bend the side edge 11, and since the side surface portion is cut off, the structure has a large magnetic resistance. Further, the method of forming into a column shape requires a drawing die. Further, in these examples, forming and drawing dies are required for each coil size.
本考案は上記したようなサイズ毎の型を不用とすること
を目的としており、又、磁気的な抵抗も極めて小さく、
シールド効果の大きいカバーを提供することを目的とす
る。The present invention aims to eliminate the above-mentioned size-specific molds, and also has extremely small magnetic resistance.
The purpose is to provide a cover with a large shield effect.
上記目的を達成するために、底面部の構成をサイズに関
わらず同じ形状の集合体とし、又、磁気的抵抗分を小さ
くする為側面を一体のものとした。In order to achieve the above-mentioned object, the structure of the bottom portion is an aggregate having the same shape regardless of the size, and the side surfaces are integrated so as to reduce the magnetic resistance.
同形状の底面部と側面部とが一体形状であるため磁気抵
抗が少なくでき、しかも成形に際しては専用形が不要と
なる。Since the bottom surface and the side surface of the same shape are integrally formed, the magnetic resistance can be reduced, and a dedicated shape is not required at the time of molding.
第１図は本考案の一例で底面が八角形の柱状のものの底
面図である。第２図はその斜視図である。第３図は、板
の加工形状である。図の如く側面に相当する部分１に底
面に相当する部分を８分割した形状を２一体にしたもの
である。第４図のように、点線A-Aで折曲げ、これをそ
れぞれのB,Bで折曲げると、第２図のようになる。13と1
4は重ね合わさることになる。このようにすることによ
り側面には切れ目がなくなるので磁気抵抗は少なく出来
る。底面は三角形の組合わせであり、コイルサイズが変
わってもこの形状は変わらない。従って、三角形の切欠
き型が一つあればよい。FIG. 1 is a bottom view of an example of the present invention in which the bottom surface is an octagonal column. FIG. 2 is a perspective view thereof. FIG. 3 shows the processed shape of the plate. As shown in the figure, a portion 1 corresponding to the side surface and a portion corresponding to the bottom surface are divided into eight, and the shape is integrated into two. As shown in FIG. 4, when it is bent along the dotted line AA and then it is bent along B and B, it becomes as shown in FIG. 13 and 1
4 will be overlaid. By doing so, there is no break on the side surface, and the magnetic resistance can be reduced. The bottom surface is a combination of triangles, and this shape does not change even if the coil size changes. Therefore, only one triangular notch type is required.
本考案は以上説明したように、平板に三角形の突起を連
接した形状に作成し、これを曲げて簡単に作成すること
が出来るので、三角形の切欠き型と、曲げ型のみあれば
良く、サイズが変わっても専用の型が不用となるので、
経済性に優れており、又、磁気部品の磁束に対する、磁
気抵抗も少なく出来るので磁束の洩れも少なくなり、磁
気シールド効果が大きくなる。As described above, since the present invention can be easily made by forming a triangular protrusion on a flat plate and bending it, it is sufficient if there is only a triangular notch type and a bending type. Even if is changed, the dedicated type is unnecessary, so
It is excellent in economic efficiency, and the magnetic resistance to the magnetic flux of the magnetic parts can be reduced, so that the leakage of the magnetic flux is reduced and the magnetic shield effect is increased.
