【発明の詳細な説明】
〈産業上の利用分野〉
本発明は巻線構造体に関し、詳しくは、製造が容易で安
価であるばかりでなく、渦電流による損失が少ないなど
、すぐれた特性を有する巻線構造体に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a wire-wound structure, and specifically, it is not only easy to manufacture and inexpensive, but also has excellent characteristics such as low loss due to eddy current. It relates to a winding structure.
〈従来の技術〉
周知のように、各穐電力用もしくは通信用変圧器は、鉄
心に一次および二次巻線を巻いて形成される。<Prior Art> As is well known, each power or communication transformer is formed by winding primary and secondary windings around an iron core.
すなわち、第２図（ａ）および（ｂ）にそれぞれ示した
ように、従来の変圧器は、鉄心１に巻線２を巻いた内鉄
型と、巻線２のまわシを鉄心１で囲んだ外鉄をに分類さ
れるが、いずれの場合も、鉄心１としては、薄い鉄板を
多数重ねたものが広く用いられていた。１個の巻線のみ
を用いた塞流コイル（チョーキングコイル）も同様であ
シ、薄い鉄板を多数重ねて形成された鉄心に巻線を多数
回巻いて形成されていた。In other words, as shown in FIGS. 2(a) and 2(b), conventional transformers are of the inner iron type, in which the winding 2 is wound around the iron core 1, and in the inner iron type, in which the winding 2 is surrounded by the iron core 1. However, in both cases, the core 1 was a stack of many thin iron plates. A choking coil using only one winding was similar, and was formed by winding the winding many times around an iron core formed by stacking many thin iron plates.
〈発明が解決しようとする問題点〉
上記のように従来の変圧器や寒流コイルは、多数の薄い
鉄板を重ねて形成された鉄心に、巻線を多数巻いて形成
された。<Problems to be Solved by the Invention> As described above, conventional transformers and cold current coils are formed by winding a large number of windings around an iron core formed by stacking a large number of thin iron plates.
しかし、第２図に示した形状の鉄板を多数重ね、これに
巻線を多数巻くのが極めて煩雑なのはいうまでもないこ
とであり、そのため、従来の変圧器や寒流コイルで（才
、製造コストが価格の大きな部なお、変圧器や寒流コイ
ルは、いずれも多数回巻いた巻線と鉄心を有しているの
で、本願明細書では、このような巻線と鉄心を有するも
のを総称として巻線構造体と記す。However, it goes without saying that it is extremely complicated to stack a large number of iron plates with the shape shown in Figure 2 and wind a large number of windings around them. However, since transformers and cold current coils both have windings and iron cores with many turns, in this specification, those with such windings and iron cores are collectively referred to as windings. It is written as a line structure.
本発明の目的は、従来の巻線構造体の有する上記問題を
解決し、製造が極めて容易で製造コストの低い巻線構造
体を提供することである。An object of the present invention is to solve the above-mentioned problems of conventional winding structures, and to provide a winding structure that is extremely easy to manufacture and has low manufacturing costs.
〈問題点を解決するための手段〉
上記目的を達成するため、本発明は、鉄など軟磁性体の
粉末を実質的に均一に含む有機樹脂の成形体中に巻線を
埋設するものである。<Means for Solving the Problems> In order to achieve the above object, the present invention embeds a winding wire in a molded body of organic resin that substantially uniformly contains powder of a soft magnetic material such as iron. .
〈作用〉
変圧器や寒流コイルなどの鉄心が、従来のように、薄い
鉄板を多数重ねて形成されたものではなく、軟磁性体の
粉末を含む樹脂の成形体であるため、多数の鉄板を重ね
る工程が不要になる。しかも１巻線が樹脂の成形体中に
埋設されて−るため。<Function> The iron core of transformers, cold current coils, etc. is not formed by stacking many thin iron plates as in the past, but is made of a resin molded body containing soft magnetic powder. No need for layering process. Moreover, one winding is embedded in the resin molding.
第２図に示した形状の鉄心に、巻線を多数回巻く工程も
不要になり、あらかじめ形成した巻線を、上記軟磁性体
粉末を含む有機樹脂内に入れて成形すればよいのである
から、製造は極めて容易であり、価格も低くなる。The process of winding the winding wire many times around the iron core having the shape shown in Fig. 2 is no longer necessary, and the pre-formed winding wire can be molded by placing it in the organic resin containing the soft magnetic powder. , manufacturing is extremely easy and the price is low.
さらに、軟磁性体粉末を含む有機樹脂によって巻線が完
全に包囲されているため、巻線の相当大きな部分が空間
に露出されていた、上記従来の巻線構造体にくらべて、
漏洩磁界が少ない、および磁気抵抗が小さい力ど、すぐ
れた特性を有している。Furthermore, since the winding is completely surrounded by an organic resin containing soft magnetic powder, compared to the conventional winding structure described above, in which a considerable portion of the winding is exposed to space,
It has excellent properties such as low leakage magnetic field and low magnetic resistance.
また、巻線と軟磁性体が樹脂中に埋設されているため、
湿気やガスなど雰囲気の影響を受ける恐れもほとんどな
く１機械的な衝撃や振動に対する耐性も極めて大きい。In addition, since the winding wire and soft magnetic material are embedded in the resin,
There is almost no risk of being affected by the atmosphere such as moisture or gas, and it has extremely high resistance to mechanical shock and vibration.
〈実施例〉
第１図１ａ） 、 （ｂ）は本発明全変圧器に適用した
実施例を示す図であ）、それぞれ、従来の上記外鉄型お
よび内鉄型変圧器に相当する。<Embodiment> FIGS. 1a) and 1(b) are diagrams showing an embodiment in which the present invention is applied to a total transformer), which correspond to the above-mentioned conventional outer iron type and inner iron type transformers, respectively.
第１図から明らかなように１本発明によれば、巻線３，
４は、軟磁性体粉末が実質的に均一に添加されである有
機高分子樹脂５内に埋設され、変圧機が構成される。As is clear from FIG. 1, according to the present invention, the windings 3,
The transformer 4 is embedded in an organic polymer resin 5 to which soft magnetic powder is substantially uniformly added.
すなわち、たとえば銅などのような導電性材料からなる
線を巻いてあらかじめ巻＃ｊ（コイル）を成

リコン合金、フェライトもしくはパーマロイ等の軟磁性
体の粉末を添加し、よく混合した有機高分子〜１脂（た
とえばナイロン系樹脂）を上記金型に射出し、周知の方
法によって成形することにより、第１図に示した変圧器
が形成される。That is, for example, a wire made of a conductive material such as copper is wound to form a winding #j (coil) in advance, and this is loaded into a molding die. For example, a powder of soft magnetic material such as iron-silicon alloy, ferrite, or permalloy is added and a well-mixed organic polymer to resin (for example, nylon resin) is injected into the above-mentioned mold and molded by a well-known method. As a result, the transformer shown in FIG. 1 is formed.
軟磁性体粉末の種類およびバインダーである有機高分子
樹脂との混合比を適宜選択することによって、所望の電
気特性を容易に得ることができ、たとえば、フェライト
の粉末を用することによって高周波特性のすぐれた変圧
器が得られる。By appropriately selecting the type of soft magnetic powder and the mixing ratio with the organic polymer resin that is the binder, desired electrical characteristics can be easily obtained. For example, by using ferrite powder, high frequency characteristics can be obtained. An excellent transformer can be obtained.
軟磁性体粉末の含有量が少なすぎると、非磁性部分が多
くなって特性が低下してしまうので、軟磁性粉末の含有
量があまり少ないのは好ましくない。しかし、軟磁性体
粉末の含有量があ１＃）多すぎると、有機高分子樹脂の
バインダーとしての効果が低下し、機械的強度や耐湿性
などが低下する恐れがあるので、軟磁性体粉末の含有量
を過度に多くするのは避けた方が好ましい。If the content of the soft magnetic powder is too small, the non-magnetic portion will increase and the properties will deteriorate, so it is not preferable that the content of the soft magnetic powder is too small. However, if the content of the soft magnetic powder is too high (1#), the effect of the organic polymer resin as a binder will decrease, and there is a risk that the mechanical strength and moisture resistance will decrease. It is preferable to avoid increasing the content excessively.
好ましい含有量の範囲は、軟磁性体粉末の種類や粒径、
使用された有機高分子樹脂の種類、および変圧器の種類
などによって異なシ、適宜選択されるが、約２０重量パ
ーセント前後にすれば、いずれの場合においても、好ま
しい結果を得られることが確認された。The preferred content range depends on the type and particle size of the soft magnetic powder,
Although it is selected as appropriate depending on the type of organic polymer resin used and the type of transformer, it has been confirmed that favorable results can be obtained in any case if the amount is around 20% by weight. Ta.
有機高分子樹脂は、所望の形状に成形されて所定の強度
を有Ｉ２、バインダーとして用い得る樹脂ならば、多く
の場合、樹脂の種類を特に限定する必要はなく、たとえ

脂を使用できる。In most cases, it is not necessary to particularly limit the type of organic polymer resin, as long as it can be molded into a desired shape, has a certain strength, and can be used as a binder. For example, nylon or polyimide resins are used. Many species A1 resins can be used, such as.
軟磁性体としては、純鉄やケイ素鉄のみではなく、パー

ように所望の高周波特性を得ることも容易である。As the soft magnetic material, use not only pure iron or silicon iron but also well-known soft magnetic materials such as permalloy, mu-metal, iron-silicon-aluminum alloy, and supermalloy, depending on the purpose. For example, it is easy to obtain desired high frequency characteristics as described above.
本実施例は、２個の巻線を有する変圧器て関するもので
あるが、巻線が１個のみである寒流コイルの場合と全く
同様であることはいうまでもない。Although this embodiment relates to a transformer having two windings, it goes without saying that it is exactly the same as a cold current coil having only one winding.
この場合も、変圧器の場合と同様に、あらかじめ形成さ

であることはいうまでもない。It goes without saying that the usable organic polymer position [type of fat, soft magnetic material, content of soft magnetic powder, etc.] is the same as in the case of the above transformer.
〈発明の効果〉

めて特異な構造を有している。<Effects of the Invention> It has a very unique structure in which the winding wire is embedded in an organic polymer resin.
そのため、多数の薄い鉄板を重ねて形成された鉄心に、
巻線を多数回巻いて形成された従来の巻線構造体よりも
、製造がはるかに容易であシ、製造コストも低い。Therefore, in the iron core formed by stacking many thin iron plates,
