しかしながら、上記のように中足2a′の先端部分に磁気ギャップ2b′を形 成したものでは、磁気ギャップ2b′は切欠状で窓部1a′まで開放しており、 かつ外部に露出しているような状態となっているため、図13において矢印で示 すように、外部へのリーケージフラックスAが大きく、周辺の電子機器および/ もしくは機器に悪影響を及ぼすおそれがあった。 また、E型鉄心2′とI型鉄心3′とを組合せる場合、図12に示すように、 E型鉄心2′の両足2c′と、これと対向配置されるI型鉄心3′とを、側部に おいて溶接Bして一体化せざる得ず、組立ライン中に溶接設備が必要になるとい う設備的な制約を受けるとともに、溶接工程をも必要となり、設備面が煩雑であ る、という課題があった。 However, in the case where the magnetic gap 2b 'is formed at the tip portion of the midfoot 2a' as described above, the magnetic gap 2b 'is notched and is open to the window portion 1a' and is exposed to the outside.

【課題を解決するための手段】[Means for Solving the Problems]

この考案は、E型鉄心2とI型鉄心3とからなる鉄心1とを備え、かつE型鉄 心2の中足2aの周囲にコイル4が巻装されてなるリアクターにおいて、前記E 型鉄心2の中足2aの中央に略長孔状をなし、その長さ方向に沿った中央線aに 対し対称形状をなす磁気ギャップ2bを形成することにより、上記目的を達成し ている。 This invention is a reactor comprising an iron core 1 composed of an E-shaped iron core 2 and an I-shaped iron core 3, and a coil 4 wound around a middle leg 2a of the E-shaped iron core 2, wherein the E-shaped iron core is The above-mentioned object is achieved by forming a substantially elongated hole at the center of the second leg 2a of the second leg 2 and forming a magnetic gap 2b having a symmetrical shape with respect to the center line a along the length direction.

【0006】[0006]

【作用】[Action]

本考案では、磁気ギャップ2bを、外周にコイル4が巻装されるE型鉄心2の 中足2aの中央にし、略長孔状とし、外部へのリーケージフラックを減少させる ようにしている。また、磁気ギヤップ形状をその中央線aに対し対称形状とし、 一枚組で鉄心1を組立可能とし、この場合、溶接設備を不要とした。 In the present invention, the magnetic gap 2b is located at the center of the middle leg 2a of the E-shaped iron core 2 around which the coil 4 is wound, and has a substantially oblong shape so as to reduce leakage flux to the outside. Further, the magnetic gear-up shape is symmetrical with respect to the center line a, and the iron core 1 can be assembled by a set of one piece. In this case, welding equipment is unnecessary.

【0007】[0007]

【実施例】【Example】

図1は本考案に用いられる鉄心1を示す。この鉄心1は、E型鉄心2の中足2 aの中央に中足長さ方向に対し直交して延びる磁気飽和特性調整用の磁気ギャッ プ2bを形成している。すなわち、中足2aの全長をXとすると、その1/2の X/2の寸法が丁度磁気ギャップ2bの長さ方向に沿った中央線aとなっている 。そして、磁気ギャップ2bは略長孔状となっており、この略長孔形状はこの中 央線aに対し対称形をなしている。また、中足2aの両側の窓部1aの中心に位 置している。 FIG. 1 shows an iron core 1 used in the present invention. In the iron core 1, a magnetic gap 2b for adjusting magnetic saturation characteristics is formed at the center of the middle leg 2a of the E-shaped iron core 2 and extends perpendicularly to the length direction of the middle leg. That is, assuming that the total length of the middle foot 2a is X, a dimension of X / 2, which is 1/2 thereof, is just the center line a along the longitudinal direction of the magnetic gap 2b. The magnetic gap 2b has a substantially long hole shape, and this substantially long hole shape is symmetrical with respect to the center line a. Moreover, it is located at the center of the windows 1a on both sides of the middle foot 2a.

【0008】 このため、鉄心1の組立てにあたり、図2の上側に示すように、積層されるE 型鉄心2とI型鉄心3との向きを積層方向において交互に異ならせて組込み、図 2の下側に示すように一枚組でもって組立ても中足2aの中央に所定の略長孔形 状の磁気ギャップ2bを得ることができる。すなわち、磁気ギャップ2bが中足 2aの中央位置であって中央線aに対し対称形状でないと一枚組による場合、所 定位置に磁気ギャップ2bを得ることができない。しかして、一枚組とした本考 案では溶接設備、溶接工程等を省くことができる。 なお、従前のように、溶接を用いても良いことは勿論であり、一枚組のみなら ず、必要に応じ選択的に溶接によっても組立可能であり、この場合、既存の設備 を利用し得る。Therefore, in assembling the iron core 1, as shown in the upper side of FIG. 2, the E-shaped iron core 2 and the I-shaped iron core 3 to be laminated are assembled by alternately changing the directions in the laminating direction. As shown in the lower side, a predetermined substantially elongated hole-shaped magnetic gap 2b can be obtained in the center of the middle leg 2a even if it is assembled by one set. That is, unless the magnetic gap 2b is in the center position of the metatarsal 2a and has a symmetrical shape with respect to the center line a, the magnetic gap 2b cannot be obtained at the predetermined position in the case of a set of one disc. Therefore, in the case of this single-piece set, welding equipment, welding process, etc. can be omitted. Of course, as in the past, it is possible to use welding, and it is possible to assemble not only a set of one piece but also welding as needed. In this case, existing equipment can be used. .

【0009】 しかして、図3に示すように、一枚組からなる鉄心1の中足2aにコイル4を 組込むなどすればリアクターを完成させることができる。この場合、磁気ギャッ プ2bは中足2aの先端でなく、中足2aの中央であって略長孔形状をなし、か つその外側にコイル4が巻装され、コイル4内であるため、外部へのリーケージ フラックスを減少させることができる。 なお、従来の溶接による鉄心1であっても、同様にリーケージフラックスを減 少させることができる。Then, as shown in FIG. 3, the reactor can be completed by assembling the coil 4 into the middle leg 2a of the iron core 1 consisting of one piece. In this case, the magnetic gap 2b is not the tip of the middle foot 2a but the center of the middle foot 2a and has a substantially oblong shape, and the coil 4 is wound on the outside thereof and is inside the coil 4. The leakage flux to the outside can be reduced. Even with the iron core 1 formed by conventional welding, the leakage flux can be similarly reduced.

【0010】 図4ないし図11は中足2aの中央に設けられる略長孔状の磁気ギャップ2b の形状の他の実施例であり、このように、略長孔状の磁気ギャップ2bの側部に 更に適宜の形状の切欠きを付設したり、磁気ギャップ2bの中心に孔部を設けた り、また他磁気ギャップ2bの形状としては複数の円形の孔を組合せるなどした り、その他図示の如く各種の態様のものが考えられる。FIGS. 4 to 11 show another embodiment of the shape of the substantially elongated hole-shaped magnetic gap 2b provided in the center of the middle foot 2a. Thus, the side portions of the substantially elongated hole-shaped magnetic gap 2b are as described above. In addition, a notch of an appropriate shape may be additionally provided, a hole may be provided at the center of the magnetic gap 2b, and a plurality of circular holes may be combined as the shape of the other magnetic gap 2b. As described above, various modes are possible.

【0011】[0011]

【考案の効果】[Effect of device]

以上のように本考案によれば、磁気ギャップ2bを中足2aの中央に設け、略 長孔状としたため、外部へのリーケージフラックスを減少させることができる。 また、磁気ギャップ2bの形状をその中央線aに対し対称形状とすることによ り、鉄心1を一枚組とすることもでき、設備的制約を受けることはない。 As described above, according to the present invention, since the magnetic gap 2b is provided in the center of the middle leg 2a and has a substantially long hole shape, leakage flux to the outside can be reduced. Further, by making the shape of the magnetic gap 2b symmetrical with respect to the center line a, the iron cores 1 can be made into one set, and there is no facility restriction.
