［第一実施形態］
（リアクトルの構成）
　以下、本開示の第一実施形態に係るリアクトル１００、及びリアクトル用電磁鋼板９０について、図１と図２を参照して説明する。 [First embodiment]
(Reactor configuration)
Hereinafter, a reactor 100 and an electromagnetic steel sheet 90 for a reactor according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 and 2. FIG.
　リアクトル１００は、電気回路上でリアクタンスを発生させるために用いられる部品である。図１に示すように、リアクトル１００は、コア１と、２つのコイル（第一コイル５１、及び第二コイル５２）と、を備えている。 A reactor 100 is a component used to generate a reactance on an electric circuit. As shown in FIG. 1, the reactor 100 includes a core 1 and two coils (a first coil 51 and a second coil 52).
（コアの構成）
　コア１は、板状のリアクトル用電磁鋼板９０を厚さ方向に複数積層することで形成されている。リアクトル用電磁鋼板９０は、中央部品１ａと、一対の外側部品１ｂと、を有している。 (core configuration)
The core 1 is formed by laminating a plurality of plate-shaped reactor electromagnetic steel sheets 90 in the thickness direction. A reactor electromagnetic steel sheet 90 has a central component 1a and a pair of outer components 1b.
　中央部品１ａは、第一方向Ｄ１に延びる第一部分１１と、第一方向Ｄ１に直交する第二方向Ｄ２に延びる複数（６つ）の第二部分１２と、を有している。第二部分１２は、第一部分１１の第二方向における両側の端縁にそれぞれ３つずつ設けられている。第二部分１２は、第一部分１１と一体に形成されており、同一の面内に広がる板状をなしている。また、第一方向Ｄ１における第二部分１２同士の間の離間寸法は互いに同一である。なお、ここで言う「同一」とは実質的な同一を指すものであって、製造上の誤差や設計上の公差は許容される。以下の説明においても同様である。 The central component 1a has a first portion 11 extending in the first direction D1 and a plurality (six) of second portions 12 extending in a second direction D2 orthogonal to the first direction D1. Three second portions 12 are provided on each of the edges on both sides of the first portion 11 in the second direction. The second portion 12 is formed integrally with the first portion 11 and has a plate shape extending in the same plane. Also, the distances between the second portions 12 in the first direction D1 are the same. It should be noted that the term "same" as used herein means substantially the same, and manufacturing errors and design tolerances are allowed. The same applies to the following description.
　第一方向Ｄ１における両側に位置する４つの第二部分１２は、第一部分１１の第一方向Ｄ１における両端部にそれぞれ設けられている。つまり、第一部分１１は、第一方向Ｄ１の両側に突出していない。 The four second portions 12 positioned on both sides in the first direction D1 are provided at both ends of the first portion 11 in the first direction D1. That is, the first portion 11 does not protrude on both sides in the first direction D1.
　なお、６つの第二部分１２のうち、第一方向Ｄ１の中央に位置する一対の第二部分１２は、残余の第二部分１２に比べて第二方向Ｄ２における寸法が小さくてもよい。これは、後述する外側部品１ｂとの間にエアギャップを形成するためである。 Of the six second portions 12, the pair of second portions 12 located in the center in the first direction D1 may have smaller dimensions in the second direction D2 than the remaining second portions 12. This is for forming an air gap with the outer part 1b, which will be described later.
　外側部品１ｂは、中央部品１ａにおける３つの第二部分１２同士を第一方向Ｄ１に接続している。言い換えれば、外側部品１ｂは、３つの第二部分１２にまたがるようにして第一方向に延びている。 The outer component 1b connects the three second portions 12 of the central component 1a in the first direction D1. In other words, the outer component 1 b extends in the first direction across the three second portions 12 .
（コイルの構成）
　第一コイル５１、及び第二コイル５２は、第一方向Ｄ１における中央の第二部分１２にそれぞれ線材を複数回巻きまわすことで形成される。つまり、このリアクトル１００は２つの独立したコイルを有している。線材の巻き方としてはこれまで提唱されている種々の態様を採ることが可能である。 (Coil configuration)
The first coil 51 and the second coil 52 are each formed by winding a wire around the central second portion 12 in the first direction D1 multiple times. That is, this reactor 100 has two independent coils. Various modes that have been proposed so far can be adopted as the method of winding the wire.
　リアクトル１００を形成するに当たっては、上記のような形状に打ち抜き加工された中央部品１ａ、及び外側部品１ｂを厚さ方向に複数積層した後、線材を巻きまわして第一コイル５１、及び第二コイル５２を形成する。その後、中央部品１ａの積層体と、外側部品１ｂの積層体とを溶接することで、リアクトル１００が完成する。 In forming the reactor 100, after stacking a plurality of the central component 1a and the outer component 1b punched into the above shape in the thickness direction, a wire is wound around to form the first coil 51 and the second coil. form 52; After that, the reactor 100 is completed by welding the laminate of the central part 1a and the laminate of the outer part 1b.
（リアクトル用電磁鋼板の打ち抜き形状について）
　次いで、図２を参照して、リアクトル用電磁鋼板９０の打ち抜き形状について説明する。リアクトル用電磁鋼板９０を打ち抜く際のダイ（刃）は、図２に示す形状となっている。即ち、中央部品１ａの第二部分１２同士が互いに対向した状態で配列された状態で、第二部分１２同士の間の領域に外側部品１ｂが配置された状態となっている。したがって、外側部品１ｂの第一方向Ｄ１における寸法は、第一方向Ｄ２における第二部分１２の寸法の２倍である。つまり、互いに対向配置された一対の中央部品１ａにおいて、４つの第二部分１２によって囲まれた領域の面積を埋めるように外側部品１ｂが配置されている。また、これにより、第二方向Ｄ２における外側部品１ｂの寸法（幅寸法）は、第一方向Ｄ１における第二部分１２同士の間の離間距離と同一である。 (Regarding punching shape of electromagnetic steel sheet for reactor)
Next, with reference to FIG. 2, the punched shape of the reactor electromagnetic steel sheet 90 will be described. A die (blade) for punching the reactor electromagnetic steel sheet 90 has a shape shown in FIG. That is, the second parts 12 of the central part 1a are arranged facing each other, and the outer part 1b is arranged in the region between the second parts 12. As shown in FIG. Therefore, the dimension of the outer part 1b in the first direction D1 is twice the dimension of the second portion 12 in the first direction D2. That is, the outer part 1b is arranged so as to fill the area of the region surrounded by the four second parts 12 in the pair of central parts 1a arranged to face each other. Moreover, thereby, the dimension (width dimension) of the outer component 1b in the second direction D2 is the same as the separation distance between the second portions 12 in the first direction D1.
（作用効果） (Effect)
　従来、コア１を製造するに当たっては、所定の形状を有する部品を打ち抜き加工によって得ることが一般的であった。当該部品を複数積層した後、互いに溶接することで１つのコアが形成される。しかしながら、従来のコアの構成では、電磁鋼板の打ち抜きに際して無駄な部分が生じやすく、歩留まりの改善が望まれていた。 Conventionally, when manufacturing the core 1, it was common to obtain parts having a predetermined shape by punching. A core is formed by stacking a plurality of such parts and then welding them together. However, in the conventional core configuration, wasteful portions are likely to occur when punching the electromagnetic steel sheet, and improvement in yield has been desired.
　上記構成によれば、中央部品１ａと外側部品１ｂとを打ち抜き加工によって形成する際に材料となる板材の歩留まりを向上させることができる。つまり、無駄となる部分を低減することができる。具体的には、一対の中央部品１ａを、第二部分１２同士が対向するように組み合わせた状態で、互いに隣接する第二部分１２同士の間に外側部品１ｂを配置した状態で打ち抜き加工を行うことができる。これにより、歩留まりを向上させることができる。 According to the above configuration, it is possible to improve the yield of the plate material used when forming the central part 1a and the outer part 1b by punching. That is, it is possible to reduce the wasteful portion. Specifically, the pair of central parts 1a are combined so that the second parts 12 face each other, and the outer part 1b is arranged between the second parts 12 adjacent to each other, and the punching process is performed. be able to. Thereby, the yield can be improved.
　また、上記構成によれば、第二方向Ｄ２における外側部品１ｂの寸法が第二部分１２の突出長さの２倍とされていることにより、第二部分１２同士の間に形成される領域を外側部品１ｂとして無駄なく使用することができる。 Further, according to the above configuration, the dimension of the outer component 1b in the second direction D2 is set to be twice the projecting length of the second portion 12, so that the area formed between the second portions 12 is It can be used without waste as the outer part 1b.
　さらに、上記構成によれば、第一方向Ｄ１における外側部品１ｂの寸法が第二部分１２同士の間の離間寸法と同一とされていることにより、第二部分１２同士の間に形成される領域を外側部品１ｂとしてさらに無駄なく使用することができる。これにより、一枚の鋼板からリアクトル用電磁鋼板９０を得るに当たって、歩留まりを大きく向上させることが可能となる。 Furthermore, according to the above configuration, the dimension of the outer part 1b in the first direction D1 is the same as the dimension of the separation between the second portions 12, so that the area formed between the second portions 12 can be used as the outer part 1b without waste. This makes it possible to greatly improve the yield in obtaining the reactor electromagnetic steel sheet 90 from a single steel sheet.
　また、上記のような作用効果に加えて、リアクトル１００では、２つのコイルの軸方向が同一であることから、励磁による振動をこれら２つのコイル同士の間で打ち消すことが可能となる。特に、インターリーブ方式でリアクトル１００を動作させる場合、２つのコイル同士で電流の位相が異なる状態となる。電流に含まれる基本成分とキャリア成分のうち、基本成分同士が打ち消し合うことで上記のような振動低減効果を得ることができる。一般的に、電磁鋼板で形成されたリアクトルは長辺側（つまり、外側部品１ｂ側）を筐体にねじなどで固定するが、本実施形態に係るリアクトル１００では、長辺と平行に振動が発生するため、筐体に伝わる振動を低減する事が可能である。 In addition to the above effects, in the reactor 100, since the axial directions of the two coils are the same, it is possible to cancel vibrations caused by excitation between the two coils. In particular, when the reactor 100 is operated in an interleaved manner, the phases of the currents differ between the two coils. Of the basic component and the carrier component contained in the current, the basic components cancel each other, so that the vibration reduction effect described above can be obtained. In general, a reactor formed of an electromagnetic steel sheet has its long side (that is, the side of the outer component 1b) fixed to a housing with screws or the like. Since it occurs, it is possible to reduce the vibration transmitted to the housing.
　さらに、リアクトル１００では、コア１の内側にそれぞれのコイルが収容されている。言い換えると、同一の大きさのコイルをコア１の外側に露出するように配置した場合に比べて、コア１の大きさを拡大することが可能となる。その結果、磁路の長さが全体として拡張され、結合係数を小さく抑えることができる。これにより、リアクトル１００の性能をさらに向上させることができる。 Furthermore, in the reactor 100, each coil is housed inside the core 1. In other words, the size of the core 1 can be increased compared to the case where coils of the same size are arranged so as to be exposed to the outside of the core 1 . As a result, the length of the magnetic path is extended as a whole, and the coupling coefficient can be kept small. Thereby, the performance of reactor 100 can be further improved.
　以上、本開示の第一実施形態について説明した。なお、本開示の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記第一実施形態では、中央部品１ａに片側３つずつの第二部分１２が形成されていることによって計２つのコイルを形成した例について説明した。しかしながら、設計や仕様に応じてコイルの数は４つ以上に変更することが可能である。 The first embodiment of the present disclosure has been described above. Various changes and modifications can be made to the above configuration without departing from the gist of the present disclosure. For example, in the above-described first embodiment, an example was described in which a total of two coils were formed by forming the second portions 12 of three on each side of the central component 1a. However, the number of coils can be changed to four or more depending on the design and specifications.
［第二実施形態］
　次に、本開示の第二実施形態について、図３と図４を参照して説明する。なお、上記第一実施形態と同様の構成については同一の符号を付し、詳細な説明を省略する。図３に示すように、本実施形態に係るリアクトル２００は、コア２と、２つのコイル（第一コイル５１、及び第二コイル５２）と、を備えている。 [Second embodiment]
Next, a second embodiment of the present disclosure will be described with reference to FIGS. 3 and 4. FIG. In addition, the same code|symbol is attached|subjected about the structure similar to said 1st embodiment, and detailed description is abbreviate|omitted. As shown in FIG. 3, the reactor 200 according to this embodiment includes a core 2 and two coils (a first coil 51 and a second coil 52).
（コアの構成）
　コア２は、第一実施形態と同様に、板状のリアクトル用電磁鋼板９０ｂを厚さ方向に複数積層することで形成されている。リアクトル用電磁鋼板９０ｂは、中央部品２ａと、一対の外側部品２ｂと、を有している。 (core configuration)
As in the first embodiment, the core 2 is formed by laminating a plurality of plate-shaped reactor electromagnetic steel sheets 90b in the thickness direction. The reactor electromagnetic steel sheet 90b has a central component 2a and a pair of outer components 2b.
　中央部品２ａは、第一方向Ｄ１に延びる第一部分２１と、第一方向Ｄ１に直交する第二方向Ｄ２に延びる複数（６つ）の第二部分２２と、を有している。第二部分２２は、第一部分２１の第二方向Ｄ２における両側の端縁にそれぞれ３つずつ設けられている。また、第一方向Ｄ１における第二部分１２同士の間の離間寸法は互いに同一である。 The central component 2a has a first portion 21 extending in the first direction D1 and a plurality (six) of second portions 22 extending in a second direction D2 orthogonal to the first direction D1. Three second portions 22 are provided on each of the edges on both sides of the first portion 21 in the second direction D2. Also, the distances between the second portions 12 in the first direction D1 are the same.
　第一方向Ｄ１における両側に位置する４つの第二部分１２は、第一部分１１の第一方向Ｄ１における両端部にそれぞれ設けられている。つまり、第一部分１１は、第一方向Ｄ１の両側に突出していない。 The four second portions 12 positioned on both sides in the first direction D1 are provided at both ends of the first portion 11 in the first direction D1. That is, the first portion 11 does not protrude on both sides in the first direction D1.
　外側部品２ｂは、上記の３つの第二部分１２に対して、第二方向Ｄ２から対向するように延びる３つの第三部分２３と、これら３つの第三部分２３同士を第一方向Ｄ１に接続する第四部分２４と、を有している。これにより、外側部品２ｂは全体としてＥ字型をなしている。このような外側部品２ｂの積層体が、中央部品２ａの積層体の第二方向Ｄ２両側からそれぞれ１つずつ取り付けられている。 The outer component 2b includes three third portions 23 extending in the second direction D2 so as to face the three second portions 12, and connecting the three third portions 23 to each other in the first direction D1. and a fourth portion 24 for. As a result, the outer part 2b has an E shape as a whole. Such a stack of outer components 2b is attached one by one from both sides of the stack of central components 2a in the second direction D2.
　第一部分２１に対する第二部分２２の突出長さと、第四部分２４に対する第三部分２３の突出長さは互いに同一である。また、第二部分２２同士の間の離間寸法と、第三部分２３同士の間の離間寸法は互いに同一である。さらに、第二部分２２同士の離間寸法は、３つの第二部分２２同士の間で同一である。同様に、第三部分２３同士の間の離間寸法は、３つの第三部分２３同士の間で同一である。 The projection length of the second portion 22 with respect to the first portion 21 and the projection length of the third portion 23 with respect to the fourth portion 24 are the same. Also, the distance between the second portions 22 and the distance between the third portions 23 are the same. Furthermore, the spacing dimension between the second portions 22 is the same among the three second portions 22 . Similarly, the spacing dimension between the third portions 23 is the same among the three third portions 23 .
　なお、６つの第二部分２２のうち、第一方向Ｄ１の中央に位置する一対の第二部分２２は、残余の第二部分２２に比べて第二方向Ｄ２における寸法が小さくてもよい。同様に、６つの第三部分２３のうち、第一方向Ｄ１の中央に位置する一対の第三部分２３は、残余の第三部分２３に比べて第二方向Ｄ２における寸法が小さくてもよい。これは、中央部品２ａと外側部品２ｂとの間にエアギャップを形成するためである。 Of the six second portions 22, the pair of second portions 22 located in the center in the first direction D1 may have smaller dimensions in the second direction D2 than the remaining second portions 22. Similarly, of the six third portions 23, the pair of third portions 23 located in the center in the first direction D1 may be smaller in size in the second direction D2 than the remaining third portions 23. This is to form an air gap between the central part 2a and the outer part 2b.
（コイルの構成）
　第一コイル５１、及び第二コイル５２は、第一方向Ｄ１における中央の第二部分２２にそれぞれ線材を複数回巻きまわすことで形成される。つまり、このリアクトル１００は２つの独立したコイルを有している。線材の巻き方としてはこれまで提唱されている種々の態様を採ることが可能である。 (Coil configuration)
The first coil 51 and the second coil 52 are each formed by winding a wire a plurality of times around the central second portion 22 in the first direction D1. That is, this reactor 100 has two independent coils. Various modes that have been proposed so far can be adopted as the method of winding the wire.
（リアクトル用電磁鋼板の打ち抜き形状について）
　次いで、図４を参照して、リアクトル用電磁鋼板９０ｂの打ち抜き形状について説明する。リアクトル用電磁鋼板９０ｂを打ち抜く際のダイ（刃）は、図４に示す形状となっている。即ち、中央部品２ａの第二部分２２同士の間の間隙に、外側部品２ｂの３つの第三部分２３のうち、最も外側の第三部分２３がはめ込まれた状態となっている。このような配置を連続的に繰り返すことで、打ち抜き加工が施される。 (Regarding punching shape of electromagnetic steel sheet for reactor)
Next, with reference to FIG. 4, the punched shape of the reactor electromagnetic steel sheet 90b will be described. A die (blade) for punching the reactor electromagnetic steel sheet 90b has a shape shown in FIG. That is, the outermost third portion 23 of the three third portions 23 of the outer component 2b is fitted in the gap between the second portions 22 of the central component 2a. A punching process is performed by continuously repeating such an arrangement.
（作用効果）
　上記構成によれば、中央部品２ａにおける第二部分２２同士の間の間隙に、外側部品２ｂにおける最も外側の第三部分２３をはめ込んだ状態で配置することで、打ち抜き加工に際して無駄な部分が生じる可能性を低減することができる。 (Effect)
According to the above configuration, by arranging the outermost third portion 23 of the outer component 2b in a state of being fitted in the gap between the second portions 22 of the central component 2a, a wasteful portion is generated during punching. Possibility can be reduced.
　また、上記構成によれば、第一方向Ｄ１における第三部分２３の寸法が第二部分２２同士の間の離間寸法と同一であることにより、中央部品２ａの第二部分２２同士の間の領域を無駄なく使用することができる。 Further, according to the above configuration, since the dimension of the third portion 23 in the first direction D1 is the same as the distance between the second portions 22, the area between the second portions 22 of the central component 2a can be used without waste.
　さらに、上記のような作用効果に加えて、リアクトル２００では、２つのコイルの軸方向が同一であることから、励磁による振動をこれら２つのコイル同士の間で打ち消すことが可能となる。特に、インターリーブ方式でリアクトル２００を動作させる場合、２つのコイル同士で電流の位相が異なる状態となる。電流に含まれる基本成分とキャリア成分のうち、基本成分同士が打ち消し合うことで上記のような振動低減効果を得ることができる。一般的に、電磁鋼板で形成されたリアクトルは長辺側（つまり、外側部品２ｂ側）を筐体にねじなどで固定するが、本実施形態に係るリアクトル２００では、長辺と平行に振動が発生するため、筐体に伝わる振動を低減する事が可能である。 Furthermore, in addition to the effects described above, in the reactor 200, since the axial directions of the two coils are the same, it is possible to cancel the vibration due to excitation between these two coils. In particular, when the reactor 200 is operated in an interleaved manner, the phases of the currents differ between the two coils. Of the basic component and the carrier component contained in the current, the basic components cancel each other, so that the vibration reduction effect described above can be obtained. In general, a reactor formed of an electromagnetic steel sheet has its long side (that is, the side of the outer component 2b) fixed to a housing with screws or the like. Since it occurs, it is possible to reduce the vibration transmitted to the housing.
　以上、本開示の第二実施形態について説明した。なお、本開示の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記第二実施形態では、中央部品２ａに片側３つずつの第二部分２２が形成されていることによって計２つのコイルを形成した例について説明した。しかしながら、設計や仕様に応じてコイルの数は４つ以上に変更することが可能である。 The second embodiment of the present disclosure has been described above. Various changes and modifications can be made to the above configuration without departing from the gist of the present disclosure. For example, in the above-described second embodiment, an example has been described in which a total of two coils are formed by forming the second portions 22 of three on each side of the central component 2a. However, the number of coils can be changed to four or more depending on the design and specifications.
［第三実施形態］
　続いて、本開示の第三実施形態について、図５から図７を参照して説明する。なお、上記の各実施形態と同様の構成については同一の符号を付し、詳細な説明を省略する。図５に示すように、本実施形態に係るリアクトル３００は、コア３と、２つのコイル（第一コイル５１、及び第二コイル５２）と、を備えている。 [Third embodiment]

Of the three second portions 32, one second portion 32 (small second portion 32s) located on one side in the first direction D1 is positioned at a predetermined distance from the remaining two second portions 32. The dimension in the second direction D2 is reduced by the length (unit length in the case of FIG. 5). The unit length referred to here refers to the width of the first portion 31 in the second direction D2. Of the two remaining second portions 32, only the second portion 32 located in the center in the first direction D1 is formed slightly shorter than the remaining one second portion 32 in order to form an air gap. It is possible to That is, it is possible to make the dimensions in the second direction different among the three second portions 32 .
　このような形状の外側部品３ａが、第一方向Ｄ１を基準として点対称となるような姿勢で一対設けられている。 A pair of outer parts 3a having such a shape are provided in a position that is point symmetric with respect to the first direction D1.
　中央部品３ｂは、第一方向Ｄ１に延びるとともに、３つの第二部分３２の端部同士を接続する第三部分３３と、第一方向Ｄ１における第三部分３３の両端部から第二方向Ｄ２における互いに離間する方向にそれぞれ単位長さ（上述）の分だけ突出する一対の突出部分３４と、を有している。 The central part 3b extends in the first direction D1 and connects the ends of the three second parts 32 to each other. and a pair of projecting portions 34 each projecting a unit length (described above) in directions spaced apart from each other.
（コイルの構成）
　第一コイル５１、及び第二コイル５２は、第一方向Ｄ１における中央の第二部分３２にそれぞれ線材を複数回巻きまわすことで形成される。つまり、このリアクトル１００は２つの独立したコイルを有している。線材の巻き方としてはこれまで提唱されている種々の態様を採ることが可能である。 (Coil configuration)
The first coil 51 and the second coil 52 are each formed by winding a wire a plurality of times around the central second portion 32 in the first direction D1. That is, this reactor 100 has two independent coils. Various modes that have been proposed so far can be adopted as the method of winding the wire.

　次いで、図６と図７を参照して、リアクトル用電磁鋼板９０ｃの打ち抜き形状について説明する。リアクトル用電磁鋼板９０ｃを打ち抜く際のダイ（刃）は、図６と図７に示す形状となっている。即ち、図６に示すように、第二方向Ｄ２に一体に接続された２つの外側部品３ａからなる組が、最も外側の第二部分３２同士を係合させるようにして配置される。この時、一方の外側部品３ａの当該最も外側の第二部分３２の外辺の第二方向Ｄ２における長さと、他方の外側部品３ａの中央の第二部分３２の第二方向Ｄ２における突出長さが同一であるため、当該組の左右端が揃った状態となる。２つの外側部品３ａの組では、一方側の外側部品３ａにおける中央の第二部分３２が、他方側の外側部品３ａにおける最も外側の第二部分３２と連続するようにして結合されている。このような配置を連続的に繰り返すことで、外側部品３ａの打ち抜き加工が施される。なお、事後、又は打ち抜き加工と同時に、連結されている２つの外側部品３ａを、図６中の点線部分で切断する。 (Regarding punching shape of electromagnetic steel sheet for reactor)
Next, with reference to FIGS. 6 and 7, the punched shape of the reactor electromagnetic steel sheet 90c will be described. A die (blade) for punching the reactor electromagnetic steel sheet 90c has a shape shown in FIGS. That is, as shown in FIG. 6, a set of two outer parts 3a integrally connected in the second direction D2 are arranged so that the outermost second parts 32 are engaged with each other. At this time, the length in the second direction D2 of the outer edge of the outermost second portion 32 of one of the outer components 3a and the protruding length in the second direction D2 of the central second portion 32 of the other outer component 3a are the same, the left and right ends of the pair are aligned. In the set of two outer parts 3a, the central second part 32 of the outer part 3a on one side is connected so as to be continuous with the outermost second part 32 of the outer part 3a on the other side. By continuously repeating such an arrangement, the outer part 3a is punched. After or at the same time as the punching process, the two connected outer parts 3a are cut along the dotted lines in FIG.
　図７に示すように、中央部品３ｂは、突出部分３４同士を対向させるようにして組を形成し、平面内に複数の組を連続的に敷き詰めるようにして打ち抜き加工が施される。 As shown in FIG. 7, the central part 3b is punched so that the protruding portions 34 are opposed to each other to form groups, and a plurality of groups are continuously laid out in a plane.
　上記構成によれば、外側部品３ａの第二部分３２同士が係合した状態で配置することにより、打ち抜き加工に際して無駄な部分が生じる可能性をさらに低減することができる。また、中央部品３ｂを打ち抜く際も、平面内を隙間なく所定の形状で埋め尽くすことができるため、歩留まりを改善することができる。 According to the above configuration, by arranging the second portions 32 of the outer component 3a in an engaged state, it is possible to further reduce the possibility of producing unnecessary portions during punching. In addition, when punching out the central part 3b, it is possible to fill the plane with a predetermined shape without gaps, so that the yield can be improved.
　さらに、上記のような作用効果に加えて、リアクトル３００では、２つのコイルの軸方向が同一であることから、励磁による振動をこれら２つのコイル同士の間で打ち消すことが可能となる。特に、インターリーブ方式でリアクトル３００を動作させる場合、２つのコイル同士で電流の位相が異なる状態となる。電流に含まれる基本成分とキャリア成分のうち、基本成分同士が打ち消し合うことで上記のような振動低減効果を得ることができる。一般的に、電磁鋼板で形成されたリアクトルは長辺側（つまり、外側部品３ａ側）を筐体にねじなどで固定するが、本実施形態に係るリアクトル３００では、長辺と平行に振動が発生するため、筐体に伝わる振動を低減する事が可能である。 Furthermore, in addition to the effects described above, in the reactor 300, since the axial directions of the two coils are the same, it is possible to cancel vibrations caused by excitation between the two coils. In particular, when the reactor 300 is operated in an interleaved manner, the phases of currents differ between the two coils. Of the basic component and the carrier component contained in the current, the basic components cancel each other, so that the vibration reduction effect described above can be obtained. In general, a reactor formed of an electromagnetic steel sheet has its long side (that is, the side of the outer component 3a) fixed to a housing with screws or the like. Since it occurs, it is possible to reduce the vibration transmitted to the housing.
　以上、本開示の第三実施形態について説明した。なお、本開示の要旨を逸脱しない限りにおいて、上記の構成に種々の変更や改修を施すことが可能である。例えば、上記第三実施形態では、外側部品３ａに片側３つずつの第二部分３２が形成されていることによって計２つのコイルを形成した例について説明した。しかしながら、設計や仕様に応じてコイルの数は４つ以上に変更することが可能である。 The third embodiment of the present disclosure has been described above. Various changes and modifications can be made to the above configuration without departing from the gist of the present disclosure. For example, in the above-described third embodiment, an example has been described in which a total of two coils are formed by forming three second portions 32 on each side of the outer component 3a. However, the number of coils can be changed to four or more depending on the design and specifications.
　さらに、変形例として図８に示すように、第二部分３２のうちの１つを無くすことも可能である。つまり、この場合、一の第二部分３２の第二方向Ｄ２における寸法が０となっている。外側部品３ａをこのような形状とすることによって、打ち抜き加工に際して図８に示すようなダイ（刃）の配置（長さが０である第二部分３２同士が対向した状態で配置すること）を採ることが可能になり、歩留まりをさらに向上させることが可能となる。 Furthermore, as a modification, one of the second portions 32 can be eliminated, as shown in FIG. That is, in this case, the dimension of one second portion 32 in the second direction D2 is zero. By forming the outer part 3a into such a shape, it is possible to arrange the die (blade) as shown in FIG. It becomes possible to obtain the material, and it becomes possible to further improve the yield.
　また、図９に示すように、一の第二部分３２の第二方向Ｄ２における寸法を、上記第三実施形態よりもさらに短くすることも可能である。具体的には、上記第三実施形態では単位長さ当たりの分だけ一の第二部分３２が短く形成されている。一方で、図９の例では、所定長さとしてこの単位長さの２倍の分だけ一の第二部分３２が短く形成されている。この場合、図９に示すように、ダイ（刃）の配置がさらに効率的になり、歩留まりをさらに向上させることができる。 Also, as shown in FIG. 9, it is possible to make the dimension of one second portion 32 in the second direction D2 even shorter than in the third embodiment. Specifically, in the above-described third embodiment, one second portion 32 is formed shorter by the amount per unit length. On the other hand, in the example of FIG. 9, one second portion 32 is formed to be short by twice the unit length as the predetermined length. In this case, as shown in FIG. 9, the die (blade) arrangement becomes more efficient, and the yield can be further improved.
