Description

本発明は、各種交流機器における整流回路、雑音防止回路、共振回路等に装備される線輪部品に関し、特に、その部品構成に関するものである。   The present invention relates to a wire ring component equipped in a rectifier circuit, a noise prevention circuit, a resonance circuit, and the like in various AC devices, and more particularly to a component configuration thereof.

図１７に示すように、従来の線輪部品９０は、ループ状の磁芯に被覆導線４を巻装してなり、図１８に示すように、磁芯８３はギャップ部を有するループ状に配置した状態の磁芯片８１と、この磁芯片８１を収容する合成樹脂製の上半ケース２ａ及び下半ケース２ｂから構成されている。図１９に示すように、被覆導線４は磁芯８３の磁性体ループの中央へ導線４の先端部を挿通させ、磁芯８３の周囲に導線所定回数だけ巻き付けて形成される。この線輪部品９０においては、上半ケース２ａ及び下半ケース２ｂによって、磁芯片８１と被覆導線４の間の電気的絶縁が図られる。導線４は磁芯８３の周囲に巻き付けたときの相互の短絡を防止することを主目的として絶縁樹脂によって被覆されている。従来、閉ループの磁芯に巻線してなる被覆導線部品において、直流電流重畳時での線輪部品のインダクタンス値の低下を避ける方策として、磁芯の磁路上にギャップを設け磁気飽和を軽減する方法が取られてきた。このギャップは磁芯のギャップ部は、磁芯の円弧部を磁路の方向に対して垂直方向に貫通していた（特許文献１）。   As shown in FIG. 17, the conventional wire ring component 90 is formed by winding the coated conducting wire 4 around a loop-shaped magnetic core, and as shown in FIG. 18, the magnetic core 83 is arranged in a loop shape having a gap portion. The magnetic core piece 81 in this state and the synthetic resin upper half case 2a and lower half case 2b that accommodate the magnetic core piece 81 are constituted. As shown in FIG. 19, the coated conducting wire 4 is formed by inserting the tip of the conducting wire 4 into the center of the magnetic loop of the magnetic core 83 and winding the conducting wire around the magnetic core 83 a predetermined number of times. In the wire ring component 90, electrical insulation between the magnetic core piece 81 and the coated conductor 4 is achieved by the upper half case 2 a and the lower half case 2 b. The conducting wire 4 is covered with an insulating resin for the main purpose of preventing mutual short circuit when wound around the magnetic core 83. Conventionally, in a coated conductor part wound around a closed-loop magnetic core, as a measure for avoiding a decrease in inductance value of the ring element when DC current is superimposed, a gap is provided on the magnetic path of the magnetic core to reduce magnetic saturation. The method has been taken. The gap portion of the magnetic core penetrates the arc portion of the magnetic core in a direction perpendicular to the direction of the magnetic path (Patent Document 1).

特許第３３０９３７２号公報Japanese Patent No. 3309372

上記線輪部品の構成において、図１９に示すように、磁芯８３に被覆導線４を連続周回した巻線状態に巻き付けるためには、ループ状の磁芯８３の中央へ挿通すべき導線４の先端部を少なくとも導線総延長の半分の長さにして、巻線で未周回の導線部を直線に近い状態に維持しながら、かつ、ねじれを補正しながら巻線作業を行なう必要がある。しかしながらループ状の磁芯８３の中央へ挿通すべき被覆導線導の長さが大きくなればなるほど、作業者は巻線の長さに応じて移動し、連続的に張力の調整をしなければならず熟練作業が必要となり、工程の自動化を行うことが困難となる。ループ状の磁芯８３の中央へ挿通すべき被覆導線４を短く折り畳んでまとめれば、作業性は改善される。しかし被覆導線４を折り曲げることによって被覆導線４に癖がつき、その後の被覆導線４の巻き付けが困難となる。このように巻線作業は自動化が困難であり、生産能率が低いという問題があった。さらにこの磁芯のギャップ部は、磁芯の円弧部を磁路の方向に対して垂直方向に貫通していた。このため特に磁芯のギャップ終端上の同一磁路上が、最も磁気飽和し易い問題点があった。磁芯の円弧部を磁路の方向に対して垂直方向に貫通する場合は、磁気飽和の箇所が同じ磁路に垂直な曲面内周に集中する為、磁気飽和した体積分はエアーギャップの拡大として振る舞うからである。このため直流電流重畳特性の特性アップと生産能率との両立を実現することができなかった。   In the configuration of the above-described wire ring component, as shown in FIG. 19, in order to wind the coated conductor 4 around the magnetic core 83 in a winding state, the conductor 4 to be inserted into the center of the loop-shaped magnetic core 83. It is necessary to perform the winding work while making the tip portion at least half the length of the total length of the conductive wire, maintaining the uncirculated conductive wire portion in a state close to a straight line, and correcting the twist. However, the greater the length of the coated conductor that should be inserted into the center of the loop-shaped magnetic core 83, the more the operator must move according to the length of the winding and continuously adjust the tension. Therefore, skilled work is required, making it difficult to automate the process. If the covered conductor 4 to be inserted into the center of the loop-shaped magnetic core 83 is folded short and collected, workability is improved. However, when the coated conducting wire 4 is bent, the coated conducting wire 4 is wrinkled, and subsequent winding of the coated conducting wire 4 becomes difficult. Thus, the winding work is difficult to automate, and there is a problem that the production efficiency is low. Further, the gap portion of the magnetic core penetrates the arc portion of the magnetic core in the direction perpendicular to the direction of the magnetic path. For this reason, there is a problem that magnetic saturation is most likely to occur especially on the same magnetic path on the gap end of the magnetic core. When penetrating the arc of the magnetic core in a direction perpendicular to the direction of the magnetic path, the magnetic saturation is concentrated on the inner circumference of the curved surface perpendicular to the same magnetic path. Because it behaves as For this reason, it has been impossible to realize both the improvement of the direct current superimposition characteristic and the production efficiency.

本発明の目的は、磁芯に対する巻線作業が従来よりも容易であり、自動化が可能となる新規な構造の線輪部品、及び部分的自己飽和しにくいような直流電量重畳特性を向上させるための方法を提供することである。   An object of the present invention is to improve a wire ring component having a novel structure that makes winding work on a magnetic core easier than before and can be automated, and a DC charge superposition characteristic that is difficult to partially self-saturate.

In addition, the above-described wire ring component is obtained in which a solenoid previously produced from the coated conductor is inserted from the gap portion.

従来の線輪部品においては、図１７、図１８、図１９に示すように、磁芯片８１の全体がケースにより被われて磁芯８３は切れ目のないリング状に形成、あるいは磁芯８３の円弧部を磁路の方向に対して垂直方向に貫通していたギャップ部を有していたのに対し、本発明の線輪部品においては、図１、図２に示すように、少なくとも１つのギャップ部を備えるループ形状の磁芯１３と内周外周交互に被覆導線４を巻回してなる巻線部とからなる線輪部品２０であって、磁芯３は複数の軟磁性材料からなる磁芯片１ａ、１ｂを中心が同軸上に重ね合わせて配置し（図２（ａ）の磁芯３）、軸を中心にして各々の磁芯は、磁芯表面の絶縁層を境界に回動可能な各々の磁芯片１ａ、１ｂに対するギャップ部を備え（図２（ｂ）の磁芯１３）、より好ましくはギャップ部の相対位置を固定して構成されることを特徴とする線輪部品であることから、磁芯１３に被覆導線４を容易に巻き付けることが出来る。その上で複数の磁芯特性を活かしつつギャップ位置関係で磁気飽和の集中を避けることによって直流電流重畳特性を引き出した線輪部品を得ることができる。例えば高効率なＭｎＺｎフェライト磁芯と飽和磁束密度が高い珪素鋼０．２３ｍｍ積層磁芯とを組み合わせるような線輪部品の特性も構成することが可能である。   In the conventional wire ring component, as shown in FIGS. 17, 18, and 19, the entire magnetic core piece 81 is covered with a case, and the magnetic core 83 is formed in an unbroken ring shape, or the arc of the magnetic core 83 is formed. In contrast, the wire ring component of the present invention has at least one gap as shown in FIGS. 1 and 2 whereas the gap portion penetrated the portion in a direction perpendicular to the direction of the magnetic path. A wire ring component 20 comprising a loop-shaped magnetic core 13 having a portion and a winding portion formed by alternately winding the coated conductor 4 on the inner and outer circumferences, wherein the magnetic core 3 is a magnetic core piece made of a plurality of soft magnetic materials. 1a and 1b are arranged so that their centers are coaxially overlapped (magnetic core 3 in FIG. 2 (a)), and each magnetic core can be rotated around an axis with an insulating layer on the surface of the magnetic core as a boundary. A gap portion for each of the magnetic core pieces 1a and 1b is provided (the magnetic core 13 in FIG. 2B), which is more preferable. Properly it is because it is Senwa component characterized in that it is configured to fix the relative position of the gap portion can be wound insulated conductive wires 4 easily to the magnetic core 13. In addition, by utilizing a plurality of magnetic core characteristics and avoiding the concentration of magnetic saturation due to the gap position, it is possible to obtain a wire ring component that draws out DC current superimposition characteristics. For example, it is possible to configure the characteristics of a wire ring component in which a highly efficient MnZn ferrite magnetic core and a silicon steel 0.23 mm laminated magnetic core having a high saturation magnetic flux density are combined.

尚、上記本発明の線輪部品において、絶縁層は磁芯片を収容する樹脂製のケースで形成し、若しくは磁芯片の表面に塗布された絶縁塗料から形成する。あるいは圧力成形により形成することも可能である。磁芯のギャップ部には、磁性あるいは非磁性のギャップ充填材を装着することが可能である。ここでギャップ充填材を磁芯片とは異なる特性の磁性材料から形成した場合、１段の磁芯とそのギャップ充填材の磁気抵抗を直列合成し、さらに各々の重ね合わせた磁芯の磁気抵抗を並列接続した磁気回路が得られることになる。   In the above-described wire ring component of the present invention, the insulating layer is formed of a resin case that accommodates the magnetic core piece, or is formed of an insulating coating applied to the surface of the magnetic core piece. Alternatively, it can be formed by pressure molding. A magnetic or nonmagnetic gap filler can be attached to the gap portion of the magnetic core. Here, when the gap filler is formed of a magnetic material having a characteristic different from that of the magnetic core piece, the magnetic resistance of one stage of the magnetic core and the gap filler is combined in series, and the magnetic resistance of each superimposed magnetic core is A magnetic circuit connected in parallel is obtained.

本発明に係る線輪部品の具体的構成において、１段あたりの磁芯のギャップ部は、磁芯の円弧部を磁路の方向に対して貫通し、その複数段に対して線輪する被覆導線の断面形状は、シングル線かあるいは銅損に応じて被覆導線の分割束として構成する。   In the specific configuration of the wire ring component according to the present invention, the gap portion of the magnetic core per step penetrates the arc portion of the magnetic core with respect to the direction of the magnetic path, and is a wire ring for the plurality of steps. The cross-sectional shape of the conducting wire is configured as a single wire or as a split bundle of coated conducting wires according to copper loss.

上記本発明の線輪部品は、ギャップ部を挟んで互いに対向する１または複数の端面を有するループ状に配置した磁芯片の表面に、ギャップ部内に被覆導線が通過可能なギャップ部を残して磁芯を重ね合わせ絶縁層を形成する磁芯作製工程と、磁芯作製工程を経て得られた磁芯のギャップ部から磁芯の磁気閉ループ内の中央へ被覆導線を通過させることによって、磁芯の周囲に被覆導線を巻装する被覆導線巻装工程を有している。 Line limbus products of the present invention, the surface of the magnetic core pieces arranged in a loop having one or more end surfaces facing each other across the gap, leaving a gap which can pass coated conductive wire in the gap portion Magnetic cores are formed by overlapping the magnetic cores to form an insulating layer, and the coated conductor is passed from the gap portion of the magnetic cores obtained through the magnetic core manufacturing process to the center in the magnetic closed loop of the magnetic cores. A covered conductor winding step for winding the covered conductor around the core is provided.

上記構造によれば、被覆導線にて、磁芯のギャップ部から磁芯の磁気閉ループ内の中央へ被覆導線を通過させつつ、磁芯の周囲に被覆導線を巻回することが出来る、このため従来ように被覆導線の先端部を磁芯の磁気閉ループ内の中央へ挿通させる作業は不要となり巻線作業が従来よりも容易となる。又、被覆導線の先端部と磁芯との相対位置を固定して、回転動作させることによって、被覆導線を磁芯の周囲に巻き付けることが出来るため巻線作業の自動化が可能である。   According to the above structure, the coated conductor can be wound around the magnetic core while passing the coated conductor from the gap portion of the magnetic core to the center in the magnetic closed loop of the magnetic core. As in the prior art, the operation of inserting the tip of the coated conductor into the center of the magnetic closed loop of the magnetic core is not required, and the winding work is easier than before. In addition, since the coated conductor can be wound around the magnetic core by fixing and rotating the relative position between the tip of the coated conductor and the magnetic core, the winding operation can be automated.

本発明に係る線輪部品は、ギャップ部を有する磁芯と、該磁芯の周囲に巻装された磁芯とを具え、磁芯は前記ギャップ部を挟んで互いに対向する一対の端面を有するループ状に配置した状の磁芯と、前記ギャップ部内に被覆導線が通過可能なギャップ部を残して磁芯片の表面を覆う絶縁ボビンあるいは絶縁層とから構成されている。   A wire ring component according to the present invention includes a magnetic core having a gap portion and a magnetic core wound around the magnetic core, and the magnetic core has a pair of end faces facing each other across the gap portion. The magnetic core is arranged in a loop shape, and an insulating bobbin or an insulating layer that covers the surface of the magnetic core piece leaving a gap portion through which the coated conductor can pass in the gap portion.

上記本発明の線輪部品によれば、後述する供試結果から明らかなように、回動式の磁芯のギャップ部は、磁芯の円弧部を磁路の方向に対して垂直方向に貫通した、磁路の方向に対して垂直方向に貫通する場合に比べて、より磁気飽和しにくい特性を備え直流電流重畳特性に有利な磁芯を得ることができる。結果として高インダクタンス維持による効率を確保できる。   According to the above-described wire ring part of the present invention, as is clear from the test results described later, the gap portion of the rotating magnetic core penetrates the arc portion of the magnetic core in the direction perpendicular to the direction of the magnetic path. Thus, it is possible to obtain a magnetic core that is more resistant to magnetic saturation than the case of penetrating in the direction perpendicular to the direction of the magnetic path, and that is advantageous in direct current superposition characteristics. As a result, the efficiency by maintaining a high inductance can be secured.

具体的構成において、被覆導線の断面形状は、シングル線かあるいは銅損に応じて被覆導線の分割束として構成する。入力の電流信号の周波数が高くなればなるほど、その導体表面に電流が集中し抵抗が上昇する結果として銅損が大きくなり、効率が劣化する。この現象を表皮効果（ｓｋｉｎｅｆｆｅｃｔ）と呼び、その電流の流れる深さを表皮深さ（ｓｋｉｎｄｅｐｔｈ）ということは、広く一般に知られている。シングル線は表皮効果の影響が十分小さい場合に用い、影響あるような製品仕様においては銅損に応じて被覆導線の分割束として構成する。   In a specific configuration, the cross-sectional shape of the coated conducting wire is configured as a single wire or as a divided bundle of coated conducting wires according to copper loss. The higher the frequency of the input current signal, the greater the copper loss and the lower the efficiency as a result of the concentration of current on the conductor surface and the increased resistance. It is widely known that this phenomenon is called skin effect and the depth of current flow is called skin depth. A single wire is used when the effect of the skin effect is sufficiently small, and in a product specification that has an effect, it is configured as a split bundle of coated conductors according to copper loss.

本発明の線輪部品の構成は、ギャップ部を挟んで互いに対向する１つまたは複数の端面を有するループ状に配置した状態の磁芯片の表面に、ギャップ部内に被覆導線が通過可能なギャップ部を残して磁芯を重ね合わせ絶縁層を形成する磁芯作製工程と（図２（ａ）の磁芯３）、磁芯作製工程を経て得られた磁芯のギャップ部から磁芯の磁気閉ループ内の中央へ被覆導線を通過させること（図３、図４）によって、磁芯の周囲に被覆導線を巻装する被覆導線巻装工程を有しているので、前記通過可能なギャップ部を利用することによって、磁芯に被覆導線を容易に巻き付けることが出来る。仕上がりは図１となる。   The configuration of the wire ring component according to the present invention includes a gap portion through which a coated conductor can pass in the gap portion on the surface of a magnetic core piece in a loop shape having one or a plurality of end faces facing each other across the gap portion. Magnetic core manufacturing step of forming an insulating layer by superimposing the magnetic cores without leaving a magnetic core (magnetic core 3 in FIG. 2A), and a magnetic closed loop of the magnetic core from the gap portion of the magnetic core obtained through the magnetic core manufacturing step Since the coated conductor is wound around the magnetic core by passing the coated conductor to the center of the core (FIGS. 3 and 4), the passable gap portion is used. By doing so, the coated conductor can be easily wound around the magnetic core. The finish is shown in FIG.

上記本発明に係る線輪部品において、図５に示すように、絶縁層は、磁芯片を収容する樹脂製のケースから形成し、あるいは磁芯片の表面に塗布された絶縁塗料から形成し、もしくは圧力成形により形成することが可能である。また磁芯２３のギャップ部には、磁性あるいは非磁性のギャップ充填材５、あるいは高保持力のマグネットを装着することが可能である。ここでギャップ充填材５を磁芯片とは異なる特性の磁性材料から形成した場合、１段の磁芯とそのギャップ充填材５の磁気抵抗を直列合成し、さらに各々の重ね合わせた磁芯の磁気抵抗を並列接続した磁気回路を有する線輪部品３０が得られることになる。   In the wire ring component according to the present invention, as shown in FIG. 5, the insulating layer is formed from a resin case that accommodates the magnetic core piece, or is formed from an insulating paint applied to the surface of the magnetic core piece, or It can be formed by pressure molding. A magnetic or non-magnetic gap filler 5 or a magnet having a high holding force can be attached to the gap portion of the magnetic core 23. Here, when the gap filler 5 is formed of a magnetic material having a characteristic different from that of the magnetic core piece, the magnetic resistances of the one-stage magnetic core and the gap filler 5 are combined in series, and the magnets of the superposed magnetic cores are combined. The wire ring component 30 having a magnetic circuit in which resistors are connected in parallel is obtained.

上記本発明の線輪部品の製造方法は、ギャップ部を挟んで互いに対向する１または複数の端面を有するループ状に配置した磁芯片の表面に、ギャップ部内に被覆導線が通過可能なギャップ部を残して磁芯を重ね合わせ絶縁層を形成する磁芯作製工程と、磁芯作製工程を経て得られた磁芯のギャップ部から磁芯の磁気閉ループ内の中央へ被覆導線を通過させることによって、磁芯の周囲に被覆導線を巻装する被覆導線巻装工程を有している。 The above method of manufacturing line wheels component of the present invention, the surface of the magnetic core pieces arranged in a loop having one or more end surfaces facing each other across the gap, possible gap passage is coated conductive wire in the gap portion The core is made by overlapping the magnetic cores to form an insulating layer, and the coated conductor is passed from the gap portion of the magnetic core obtained through the magnetic core manufacturing process to the center in the magnetic closed loop of the magnetic core. And a coated conductor winding step of winding the coated conductor around the magnetic core.

上記製造方法においては、磁芯の周囲に導線を巻き付けるのではなく、予め図９の磁芯６３とは別体に、図１０に示すような空芯被覆導線６４（例えばバンク巻きソレノイド）を作製しておき、その後、図１１（ａ）に示すように、ギャップ部内に被覆導線６４が通過可能な磁芯６３を重ね合わせ、図１１（ｂ）に示すように、当該ギャップ部の中央へ空芯被覆導線６４を挿入し、磁芯６３の周囲に空芯被覆導線６４を装着する。この場合、更に巻線工程が自動化し易い構成となる。   In the manufacturing method described above, a conductor wire is not wound around the magnetic core, but an air core covered conductor 64 (for example, a bank winding solenoid) as shown in FIG. 10 is prepared separately from the magnetic core 63 of FIG. After that, as shown in FIG. 11 (a), a magnetic core 63 through which the covered conducting wire 64 can pass is overlapped in the gap portion, and as shown in FIG. 11 (b), the gap 63 is emptied to the center of the gap portion. The core-coated conductive wire 64 is inserted, and the air-core coated conductive wire 64 is attached around the magnetic core 63. In this case, the winding process is further easily automated.

尚、磁芯のギャップ部から磁芯をループ状に配置した磁芯の中央へ空芯被覆導線の一部を通過させる際、磁芯のギャップ部は、既に公知の事実としてより緩い傾斜でギャップ部からギャップ無し磁芯部に連結することができる方が空芯被覆導線をより低負荷で磁芯に挿入あるいは巻装することが可能である。   When passing a part of the air core covered conductor from the gap portion of the magnetic core to the center of the magnetic core in which the magnetic cores are arranged in a loop shape, the gap portion of the magnetic core is a gap with a gentler inclination as already known. It is possible to insert or wind the air-core-coated conductor in the magnetic core with a lower load if it can be connected to the magnetic core without gap from the portion.

適宜選択する公知の事実としては、切断するギャップ距離が大き場合に製造コストが高くなるが、より均等巻きし易く生産効率は向上する。   As a known fact to be selected as appropriate, the manufacturing cost increases when the gap distance to be cut is large, but it is easier to wind evenly and the production efficiency is improved.

磁芯のギャップ部は、磁芯の円弧部を磁路の方向に対して垂直方向に貫通する場合、従来１種類の１つの磁芯が磁気回路として用いられてきた、この場合磁気ギャップ部のギャップ幅が大きくなる程、インダクタンスは小さくなる。本発明の線輪部品によれば、少なくとも１つのギャップを備えるループ形状の磁芯と内周外周交互に被覆導線を巻回してなる巻き線部とからなる線輪部品であって、前記磁芯は複数の軟磁性磁芯を中心が同軸上に重ね合わせて配置し、前記軸を中心にして前記各々の磁芯は、磁芯表面の絶縁層を境界に回動可能な各々の磁芯に対するギャップを備え、より好ましくはギャップの相対位置を固定して構成されることを特徴とする線輪部品であることから、その回動する前記ギャップの相対位置、あるいは磁芯材質の組み合わせにより、特性の最適化が可能である。磁芯に対する空芯被覆導線の装着が容易であることと特性が最適化できることが両立できる特徴がある。   When the magnetic core gap portion penetrates the arc portion of the magnetic core in the direction perpendicular to the direction of the magnetic path, one type of conventional magnetic core has been used as a magnetic circuit. The inductance decreases as the gap width increases. According to the wire ring component of the present invention, a wire ring component comprising a loop-shaped magnetic core having at least one gap and a winding portion formed by alternately winding a coated conductive wire on the inner and outer circumferences, the magnetic core Is arranged with a plurality of soft magnetic cores coaxially overlapped with each other, and each of the magnetic cores is centered on the axis with respect to each of the magnetic cores that can rotate around the insulating layer on the surface of the magnetic core. Since it is a wire ring component provided with a gap, more preferably, the relative position of the gap is fixed, the characteristics can be determined by the relative position of the rotating gap or a combination of magnetic core materials. Can be optimized. There is a feature that it is possible to achieve both the ease of mounting the air-core-coated conductor to the magnetic core and the optimization of the characteristics.

上記の製造方法によれば、空芯被覆導線（各種ソレノイド）を別途作製するので、被覆導線として、断面形状がシングルの場合、円形のみならず、矩形もしくは台形の導線を採用することが考えられ、表皮効果の影響が影響あるような製品仕様においては銅損に応じて被覆導線の分割束として構成するしその束の断面を円形のみならず、矩形もしくは台形の導線を採用することが考えられる。   According to the above manufacturing method, air core-coated conductors (various solenoids) are separately manufactured. Therefore, when the cross-sectional shape is single, it is conceivable to adopt not only a circular but also a rectangular or trapezoidal conductor as the coated conductor. In the product specifications that are affected by the skin effect, it is possible to construct a divided bundle of coated conductors according to copper loss, and adopt a rectangular or trapezoidal conductor as well as a circular cross section. .

尚、上記本発明の線輪部品及びその製造方法において、絶縁材料で隣り合う導体間のピンホールが重なる確率が充分いような場合には、被覆された導線を用いて被覆導線を形成すれば、磁芯片と被覆導線の間の絶縁層は省略可能である。   In the above-described wire ring component and the method of manufacturing the same according to the present invention, when there is a sufficient probability that pinholes between adjacent conductors are overlapped with an insulating material, the coated conductor is formed using the coated conductor. The insulating layer between the magnetic core piece and the coated conductor can be omitted.

上記技術的課題を達成するための本発明の線輪部品は、閉磁路を形成する多角形の磁芯の一部にエアーギャップを設けた複数の磁芯を、エアーギャップ部を重ね合わせて配置、巻き線し巻き線後にエアーギャップをスライド移動し再配置することで、閉磁路の磁気回路の組み合わせを形成する手法あって、実質断面積の小さい箇所は分散配置を特徴とする。エアーギャップトロイダル磁芯の組み合わせとして閉磁路を確保し、さらに高い電気特性の要求がある場合について、本発明に係る線輪部品によれば、磁芯は複数の軟磁性磁芯を中心が同軸上に重ね合わせて配置し、前記軸を中心にして前記各々の磁芯は、磁芯表面の絶縁層を境界に回動可能な各々の磁芯に対するギャップを備えている。このためギャップ磁芯の多層化と前記ギャップの配置構成により高性能な磁芯を得られるとともに、磁芯に対する巻装が容易であり結果として自動化容易になる。更に後付でギャップ部を軟磁性、マグネットで埋めることでインダクタンスを強化することができる。ギャップ周辺の磁芯の磁気飽和を緩和し、均等巻きし易い構成とすること、すなわち省エネが可能な高効率な線輪部品を自動化により低価格で大量に供給することができる。 In order to achieve the above technical problem, the wire ring component of the present invention has a plurality of magnetic cores provided with an air gap in a part of a polygonal magnetic core forming a closed magnetic path, and the air gap portions are overlapped. by rearranging slides the air gap after winding and winding lines, there method of forming a combination of the magnetic circuit of a closed magnetic path, a small portion of substantially the cross-sectional area it characterized distributed. When a closed magnetic circuit is secured as a combination of air gap toroidal cores and there is a demand for higher electrical characteristics, according to the ring component according to the present invention, the magnetic core is coaxially centered on a plurality of soft magnetic cores. And each of the magnetic cores has a gap with respect to each of the magnetic cores that can be rotated around an insulating layer on the surface of the magnetic core. For this reason, a high-performance magnetic core can be obtained by multilayering the gap magnetic core and the arrangement configuration of the gap, and winding around the magnetic core is easy and as a result, automation is facilitated. Further, the inductance can be strengthened by filling the gap portion with a soft magnetism and a magnet later. It is possible to ease the magnetic saturation of the magnetic core around the gap and make it easy to wind evenly, that is, to supply a large amount of highly efficient wire ring parts capable of energy saving at low cost by automation.

本発明により、エネルギー蓄積量を改善した複合磁芯で省エネルギー性を高め、かつ、巻線を容易にして工業性と経済性を高めた線輪部品を提供することができた。   According to the present invention, it has been possible to provide a wire ring component that has improved energy saving performance with a composite magnetic core with an improved energy storage amount, and facilitated winding to improve industrial efficiency and economic efficiency.

(Embodiment 1)
FIG. 1 is a perspective view of a wire ring component according to Embodiment 1 of the present invention. FIG. 2 is a perspective view of a magnetic core used for the wire ring component according to Embodiment 1 of the present invention. FIG. 2 (a) is a perspective view of the magnetic core with overlapping gap portions, and FIG. FIG. 2B is a perspective view of a magnetic core in which the gap portions do not overlap. FIG. 3 is a perspective view for explaining the winding work of the coated copper wire on the wire ring component according to Embodiment 1 of the present invention. FIG. 3 (a) is a perspective view of the magnetic core, and FIG. FIG. 3C is a perspective view showing an initial winding state, and FIG. 3D is a perspective view showing a state in the middle of winding. FIG. 4 is a perspective view for explaining an automated winding method of a coated copper wire on the wire ring component according to Embodiment 1 of the present invention.

実施の形態１の線輪部品は、最もシンプルなタイプとして、２つの磁芯、各１つのギャップの構成について示す。図１に示すギャップ部を有するループ状に配置した状態の磁芯１３に被覆導線４を巻装するとともに、２つの磁芯片１ａ、１ｂの磁気ギャップの相対位置は巻装後に調整して固定しており、被覆導線４の両端部は一対のリード部を形成している。   The wire ring component according to the first embodiment will be described as the simplest type with two magnetic cores and one gap each. The coated conductor 4 is wound around the magnetic core 13 arranged in a loop shape having the gap portion shown in FIG. 1, and the relative positions of the magnetic gaps of the two magnetic core pieces 1a and 1b are adjusted and fixed after winding. Both ends of the coated conductor 4 form a pair of lead portions.

磁芯１３は、図２に示す磁気ギャップとなるギャップ部を有するループ状に配置した状態の磁芯片１ａ、１ｂと、この磁芯片１ａ、１ｂを収容する樹脂製の上半ケース２ａ及び下半ケース２ｂと上下磁芯片の仕切とから構成され、上半ケース２ａ及び下半ケース２ｂ、仕切にはそれぞれ、磁芯片１ａ、１ｂのギャップ部を露出させるための切欠きが、磁気ギャップと一致する幅に対してエッジを確実にカバーするような公差で開設されている。また上下の磁芯片１ａ、１ｂと上半ケース２ａ、仕切、下半ケース２ｂのクリアランス（隙間）を開設することで磁芯は複数の軟磁性磁芯を中心が同軸上に重ね合わせて配置し、軸を中心にして各々の磁芯は、磁芯表面の絶縁層を境界に相対して回動可能な各々の磁芯に対するギャップ部を備えることができる。   The magnetic core 13 includes magnetic core pieces 1a and 1b arranged in a loop shape having a gap portion to be a magnetic gap shown in FIG. 2, and an upper half case 2a and a lower half made of resin for housing the magnetic core pieces 1a and 1b. The upper half case 2a, the lower half case 2b, and the partition each have a notch for exposing the gap portions of the magnetic core pieces 1a and 1b to match the magnetic gap. Established with tolerances that cover the edges reliably against the width. In addition, by opening clearances (gap) between the upper and lower magnetic core pieces 1a, 1b and the upper half case 2a, the partition, and the lower half case 2b, the magnetic core is arranged by superimposing a plurality of soft magnetic cores on the same axis. Each of the magnetic cores about the axis can include a gap portion for each of the magnetic cores that can be rotated relative to the boundary of the insulating layer on the surface of the magnetic core.

上記線輪部品の製造工程においては、図２（ａ）に示すように、先ず、構成の順序として磁芯片１ａ、１ｂのギャップ部を重ね合わせて（組み合わせ後は磁芯片１の状態となる）、磁芯３をケースへ挿入し、磁芯３を巻装するとともに、 図４に示すように、磁芯３を回動し固定して構成されることを特徴とする線輪部品である。巻装段階において図３に示すように、磁芯３のギャップ部からループ状の磁芯の中央へ導線を通過させながら、磁芯３の周囲に導線４を巻き付ける。この過程で、従来のように導線４の先端部をループ状の磁芯３の中央に挿通させる作業は不要であり、導線４を磁芯３の外側からギャップ部を通過させてループ状の磁芯３の中央の内部へ移動させた後、磁芯３の周囲に巻き付ける作業を繰り返せばよい。   In the manufacturing process of the above-described wire ring component, as shown in FIG. 2A, first, the gap portions of the magnetic core pieces 1a and 1b are overlapped as the order of the configuration (after combination, the state of the magnetic core piece 1 is obtained). The wire ring component is configured by inserting the magnetic core 3 into the case, winding the magnetic core 3, and rotating and fixing the magnetic core 3 as shown in FIG. At the winding stage, as shown in FIG. 3, the conductor 4 is wound around the magnetic core 3 while passing the conductor from the gap portion of the magnetic core 3 to the center of the loop-shaped magnetic core. In this process, it is not necessary to insert the leading end portion of the conducting wire 4 into the center of the loop-shaped magnetic core 3 as in the prior art, and the conducting wire 4 is passed through the gap portion from the outside of the magnetic core 3 to make a loop-shaped magnetic core. What is necessary is just to repeat the operation | work wound around the magnetic core 3, after moving to the center inside of the core 3. FIG.

従って巻装は従来よりも容易になり、結果として自動化し易い。尚、小量多品種のように自動化するメリットが大きくない場合は、前記磁芯をケースへ挿入（磁芯ギャップ重ね合わせ）と磁芯を回動し固定とを同時に実施してしまい、従来のように導線の先端部を磁芯のループ状の磁芯の中央に挿通させる作業方法を採用する場合、図１９があり得る。この場合、磁芯片のギャップ部を露出させるための切欠きは省略可能である。   Therefore, winding becomes easier than before, and as a result, it is easy to automate. If the merit of automation is not large as in the case of a small variety of products, the magnetic core is inserted into the case (magnetic core gap overlap) and the magnetic core is rotated and fixed at the same time. In the case of adopting a working method in which the leading end portion of the conducting wire is inserted through the center of the loop-shaped magnetic core of the magnetic core as described above, FIG. In this case, the notch for exposing the gap portion of the magnetic core piece can be omitted.

上記の巻装の作業工程を自動化する場合、図４に示すように、１つまたは複数のリールに巻き付けられている導線４の先端部または先端部の束をループ状の磁芯３の中央にリード端子長として必要なだけ挿通させ、磁芯３の表面に沿ってフォーミング、固定し、当該被覆導線４をギャップ部を通過、移動回転（φ方向）させ、同時連動して当該磁芯３をボビンごと回動（θ方向）させることによって、導線４をリール９から繰り出しつつ、磁芯３の周囲に巻き付ける。このようにして巻線作業を自動化することにより、線輪部品の生産能率が向上するとともに、品質の向上が図られる。上記巻装により、図１に示すように、磁芯３を包囲して被覆導線４が巻装されることになる。   When automating the above-described winding work process, as shown in FIG. 4, the leading end portion of the conducting wire 4 wound around one or a plurality of reels or a bundle of the leading end portions is placed at the center of the loop-shaped magnetic core 3. Insert the lead wire as long as necessary, form and fix it along the surface of the magnetic core 3, pass the covered conductor 4 through the gap, move and rotate (φ direction), and simultaneously link the magnetic core 3 By rotating the bobbin together (θ direction), the conductor 4 is wound around the magnetic core 3 while being fed from the reel 9. By automating the winding work in this way, the production efficiency of the wire ring parts is improved and the quality is improved. As shown in FIG. 1, the coated conductor 4 is wound around the magnetic core 3 by the winding.

なお、磁芯のギャップ部の形状を、図１５に示すように、磁芯７１を用い、線輪部品８０とすることもできる。磁芯７１の最大外径を結ぶ線をＸとすると、Ｘに平行に切ってギャップを設けている。図１６は、本発明の実施の形態１の変形例における線輪部品の直流重畳特性を示す図である。寸法を内径１４ｍｍ、外径２７ｍｍ、高さ１５ｍｍ、材質をセンダストとし、５ｍｍのギャップを設けた線輪部品を準備した。図１６に示すように、図１の通常のギャップ形状の線輪部品２０（符号１０１）と直流重畳特性を比較すると、この形状（符号１０２）では、やや劣化が見られた。   In addition, the shape of the gap part of a magnetic core can also be set as the wire ring component 80 using the magnetic core 71, as shown in FIG. When a line connecting the maximum outer diameters of the magnetic core 71 is X, a gap is provided by cutting parallel to X. FIG. 16 is a diagram illustrating the DC superimposition characteristics of the wire ring component according to the modification of the first embodiment of the present invention. A wire ring component having an inner diameter of 14 mm, an outer diameter of 27 mm, a height of 15 mm, a material of sendust and a gap of 5 mm was prepared. As shown in FIG. 16, when the direct current superposition characteristics were compared with the normal gap-shaped wire ring part 20 (reference numeral 101) of FIG. 1, the shape (reference numeral 102) showed a slight deterioration.

（実施の形態２）
次に、本発明の実施の形態２を説明する。図５は、本発明の実施の形態２における線輪部品の斜視図である。図６は、本発明の実施の形態２における線輪部品に用いられる磁芯の斜視図である。さらに図５、６に示すように、磁芯２３のギャップ部に対し、ギャップに充填する充填材５として、インダクタンス指標の透磁率は１近傍の素材で固定するか、あるいはインダクタンス指標の透磁率μが１以上の素材を挿入したうえで固定するか、あるいは強磁性体マグネットを挿入することで特性を強化することができる。前記のいずれかを選択することを特徴とする線輪部品３０である。予め製作した材料を挿入し接着剤によってこれを固定する場合、あるいは接着剤、熱可塑剤などに磁性材を分散したペーストを挿入し固化させる場合、あるいはボビンの一部としてギャップ固定用のスナップフィットが備えられている場合がある。当然樹脂ボビン自体に磁性材料が分散されている場合があり得る。この結果として図１に示す線輪部品が完成し、特性的に図１２に示すような特徴が実施の形態として得られる。本発明で使用した供試は、被覆前の仕上がりの磁芯形状が内径１９ｍｍ、外径３８ｍｍ、高さ１４ｍｍ（１段あたり７ｍｍ）、ギャップ４ｍｍであり２段重ねの構成になっている。従来方法の比較対象の１段構成は内径１９ｍｍ、外径３８ｍｍ、高さ１４ｍｍ（１段）、ギャップ２ｍｍで構成した。 (Embodiment 2)
Next, a second embodiment of the present invention will be described. FIG. 5 is a perspective view of a wire ring component according to Embodiment 2 of the present invention. FIG. 6 is a perspective view of a magnetic core used for the wire ring component according to Embodiment 2 of the present invention. Further, as shown in FIGS. 5 and 6, as the filler 5 filling the gap portion of the magnetic core 23, the magnetic permeability of the inductance index is fixed with a material near 1 or the magnetic permeability μ of the inductance index. However, it is possible to enhance the characteristics by inserting one or more materials and fixing them, or inserting a ferromagnetic magnet. One of the above is selected. Snap-fit for gap fixing as part of bobbin when inserting pre-manufactured material and fixing it with adhesive, or when inserting and solidifying paste with dispersed magnetic material in adhesive, thermoplastic agent, etc. May be provided. Of course, the magnetic material may be dispersed in the resin bobbin itself. As a result, the wire ring part shown in FIG. 1 is completed, and a characteristic characteristic as shown in FIG. 12 is obtained as an embodiment. In the test used in the present invention, the finished magnetic core before coating had an inner diameter of 19 mm, an outer diameter of 38 mm, a height of 14 mm (7 mm per stage), a gap of 4 mm, and a two-tier structure. The one-stage configuration to be compared with the conventional method was configured with an inner diameter of 19 mm, an outer diameter of 38 mm, a height of 14 mm (one stage), and a gap of 2 mm.

図１２において、（ａ）は、 ＭｎＺｎフェライト１段、（ｂ）は、ＭｎＺｎフェライト１段（特許第３３０９３７２号の形状）、（ｃ）は、ＭｎＺｎフェライト２段スライド（ランタノイドマグネット固有保磁力１０ｋＯｅをギャップ部へ挿入）、（ｄ）は、ＭｎＺｎフェライト１段、珪素鋼０．２３ｍｍ積層巻き磁芯１段スライド、（ｅ）は、ＭｎＺｎフェライト２段スライド（鉄系軟磁性材料μ＝６をギャップ部へ挿入）、（ｆ）は、ＭｎＺｎフェライト２段スライド（鉄系軟磁性材料μ＝６０をギャップ部へ挿入）である。スライド量は、２段のギャップが揃った位置からの距離として４ｍｍ±１ｍｍの範囲内であった。特性比較としては極力インダクタンスを揃える内容で比較検討を行った。インダクタンスに関する透磁率について、ＭｎＺｎフェライト磁芯は２１００、珪素鋼０．２３ｍｍ積層巻き磁芯は１５０００のものを使用した。   In FIG. 12, (a) is one stage of MnZn ferrite, (b) is one stage of MnZn ferrite (the shape of Japanese Patent No. 3309372), (c) is a two stage slide of MnZn ferrite (lanthanoid magnet intrinsic coercive force 10 kOe). (Inserted into the gap part), (d) is MnZn ferrite one stage, silicon steel 0.23 mm laminated wound magnetic core one stage slide, (e) MnZn ferrite two stage slide (iron soft magnetic material μ = 6 gap) And (f) are MnZn ferrite two-stage slides (iron-based soft magnetic material μ = 60 is inserted into the gap). The slide amount was within the range of 4 mm ± 1 mm as the distance from the position where the two-step gaps were aligned. As a characteristic comparison, a comparative study was conducted with the content of arranging the inductance as much as possible. Regarding the magnetic permeability related to inductance, a MnZn ferrite magnetic core of 2100 and a silicon steel 0.23 mm laminated winding magnetic core of 15000 were used.

上記のようにギャップ充填材は、非磁性材料あるいは磁性材料から形成することが可能であって、軟磁性磁芯のギャップ部に対して、インダクタンス指標の透磁率は１近傍の素材で固定するか、あるいはインダクタンス指標の透磁率μが１以上の素材を挿入したうえで固定するか、あるいは強磁性体マグネットを挿入するかを選択することが可能であって、例えば図２（ａ）に示す磁芯３の回動前の磁芯形状や、図２（ｂ）に示す磁芯１３の回動後の磁芯形状を採用することが出来る。図１４に示すように、回動後の磁芯形状は、２段重ね合わせ磁芯の場合、シンプルに考えた場合１２通りの仕様組み合わせが考えられる。   As described above, the gap filler can be formed of a nonmagnetic material or a magnetic material, and the permeability of the inductance index is fixed to a material near 1 with respect to the gap portion of the soft magnetic core. Alternatively, it is possible to select whether to insert and insert a material having an inductance index permeability μ of 1 or more, or to insert a ferromagnetic magnet. For example, the magnetic field shown in FIG. The magnetic core shape before the rotation of the core 3 or the magnetic core shape after the rotation of the magnetic core 13 shown in FIG. 2B can be adopted. As shown in FIG. 14, the shape of the magnetic core after the rotation is considered to be 12 kinds of specification combinations when simply considered in the case of a two-stage stacked magnetic core.

巻装を自動化する場合、被覆導線は予めフォーミングされソレノイドを形成する。前記ソレノイドを構成する被覆導線の周回する形状は各方式が考えられ、例えば従来からＬＦ／ＭＦ海事及び航空送信機用の線輪として用いられてきたバンク巻き被覆導線は確立された技術である。本実施例とバンク巻き、別名ピラミッド巻き（Ｎｉｅｌｓ Ｊｏｒｇｅｎｓｅｎ、ＯＺ８ＮＪ による）線輪との組み合わせが特性、品質的に適合している。前記バンク巻きについて、巻き数の密なコイルは、５層コイルなども存在するが、巻き線を正しく保持する生産性の難しさからピラミッド巻２から３層を実施した。本実施例で空冷効率は近接損の増加を差し引いても改善している。および線間浮遊容量が低減（高いＱを得やすい）に加え、本実施の形態において磁芯から線輪が動いたり脱落したりする確率が抑制できることがわかった。   When the winding is automated, the coated conductor is pre-formed to form a solenoid. Various methods are conceivable for the shape of the sheathed conductor that constitutes the solenoid to circulate. For example, bank-wrapped conductors that have been conventionally used as wire rings for LF / MF maritime and aviation transmitters are established techniques. The combination of this embodiment and bank winding, also known as pyramid winding (by Niels Jorgensen, OZ8NJ) wire ring, is suitable in terms of characteristics and quality. As for the bank winding, although there are five-layer coils, etc., the coil having a dense number of turns, the two to three layers of the pyramid winding were carried out because of the difficulty in productivity to hold the winding correctly. In this embodiment, the air cooling efficiency is improved even if the increase in proximity loss is subtracted. In addition, the stray capacitance between the lines is reduced (it is easy to obtain a high Q), and it has been found that the probability that the wire ring moves or drops from the magnetic core can be suppressed in the present embodiment.

図１３は、磁芯材料データとしての磁芯損失を表わしている。図１３において、１１１は、ＭｎＺｎフェライト、１１２は、アモルファスｔ０．０２５ｍｍ、１１３は、方向性珪素鋼板ｔ０．２３ｍｍ、１１４は、方向性珪素鋼板ｔ０．３５ｍｍである。例えば高効率なＭｎＺｎフェライト磁芯と飽和磁束密度が高い珪素鋼０．２３ｍｍ積層磁芯とを組み合わせるような線輪部品の特性も構成することにより磁芯材料の損失的なメリットを引き出すことが可能である。   FIG. 13 shows magnetic core loss as magnetic core material data. In FIG. 13, 111 is MnZn ferrite, 112 is amorphous t0.025 mm, 113 is a directional silicon steel plate t0.23 mm, and 114 is a directional silicon steel plate t0.35 mm. For example, the lossy merit of the magnetic core material can be derived by configuring the characteristics of a wire ring component that combines a highly efficient MnZn ferrite magnetic core and a silicon steel 0.23 mm laminated magnetic core with a high saturation magnetic flux density. It is.

図１２の結果より、各電流値で比較した場合のインダクタンスの高い線輪部品の方が実駆動回路の効率が高く望ましい。従って本発明の図１２の（ｃ）、（ｄ）、（ｅ）、（ｆ）がより望ましく明らかな効果を示すことができる。   From the result of FIG. 12, the efficiency of the actual drive circuit is higher in the wire ring component having a higher inductance when compared with each current value. Therefore, (c), (d), (e), and (f) of FIG. 12 of the present invention can exhibit more desirable and obvious effects.

さらに図１３、図１４から明らかなように、従来の線輪部品よりも本発明の図１２の（ｃ）、（ｄ）、（ｅ）、（ｆ）の線輪部品の方が、磁芯損失や特性のラインナップが多く、そのラインナップを維持するため経済性が極めて良い。省エネ効果として交流機器のエネルギー効率を改善できる。さらに部材のリサイクルや分別に関しても優位な構成を獲得できる技術である。   Further, as is apparent from FIGS. 13 and 14, the wire ring components of FIGS. 12 (c), 12 (d), (e), and (f) of the present invention are more magnetic cores than the conventional wire ring components. There are many lineups of loss and characteristics, and the economics are extremely good because the lineup is maintained. The energy efficiency of AC devices can be improved as an energy saving effect. Furthermore, it is a technology that can acquire a superior structure in terms of recycling and sorting of parts.
