Description
【０００１】[0001]
本考案は電源に挿入するラインフィルターのような一対のコイルを備えた巻線 が得られる自動巻線構造コイルに関する。 The present invention relates to an automatic winding structure coil capable of obtaining a winding having a pair of coils such as a line filter to be inserted into a power supply.
【０００２】[0002]
電源ラインを介して誘導される電気機器へのノイズの除去に一対のコイルを有 するラインフィルターが用いられ、例えば特開昭６０−１４３６１２号公報には ＥＩ形、ＥＥ形、または日字形のコアの中央磁心に一対の巻線を施し、これら巻 線に通ずる電流の磁界が互いに打消し合うように通電してノイズの除去を行って いる。 A line filter having a pair of coils is used for removing noise to an electric device induced through a power supply line. For example, Japanese Patent Laid-Open No. 60-143612 discloses an EI type, EE type, or J-shaped core. A pair of windings is applied to the central magnetic core of the and the current is removed so that the magnetic fields of the currents passing through these windings cancel each other out.
【０００３】 また、トロイダル磁心を用いたラインフィルターにおいても、互いに逆方向の 磁界を生ずる２巻線に電流を通じ、商用電源に重畳する高周波雑音成分を除去し ている。Further, also in a line filter using a toroidal magnetic core, a high frequency noise component superimposed on a commercial power source is removed by passing a current through two windings which generate magnetic fields in mutually opposite directions.
【０００４】[0004]
上述の前者のＥＩ形やＥＥ形のコアの中央磁心に２巻線を巻回したものでは、 外形が大きい割に巻線スペースが少なく、従って、インダクタンスを大にするに は巻線が重なり浮遊容量が増大して高周波帯域での特性が劣化する欠点がある。 In the former EI type or EE type core with two windings wound around the central magnetic core, the winding space is small in spite of its large outer shape. Therefore, in order to increase the inductance, the windings overlap and float. There is a drawback that the capacity increases and the characteristics in the high frequency band deteriorate.
【０００５】 また後者のトロイダル磁心では巻線工程に手数を要してコストが嵩み、また量 産性が劣るという問題が生じている。In the latter toroidal magnetic core, there are problems that a winding process requires labor and costs are increased, and productivity is poor.
【０００６】 本考案はこのような問題に鑑みてなされたものであり、その目的は内鉄形鉄心 への２巻線の巻回に際し、該２巻線を同時に巻回して手数を省き、さらに巻線の 密度を下げて高周波特性を向上させようとする自動巻線構造コイルを提供するこ とにある。The present invention has been made in view of the above problems, and an object thereof is to wind two windings around an inner iron core so as to wind the two windings at the same time and save the labor. It is an object of the present invention to provide an automatic winding structure coil that attempts to improve the high frequency characteristics by reducing the winding density.
【０００７】[0007]
上述の目的を達成するために本考案によれば、ロ字状の内鉄形磁心の相対する ２辺に設けたそれぞれのボビン上に巻回する巻線を、互いに逆方向に巻付ける自 動巻線構造コイルにおいて、前記のそれぞれのボビンを磁心の外周に回転自在に 形成するとともに、これらボビンに設けた鍔部外周に歯切りを行い該歯切りによ る噛合にて両ボビンが連動する自動巻線構造コイルが提供される。 According to the present invention to achieve the above-mentioned object, the windings wound on the respective bobbins provided on the two opposite sides of the square-shaped inner iron core are automatically wound in opposite directions. In the winding structure coil, each of the above bobbins is rotatably formed on the outer circumference of the magnetic core, and the outer circumference of the collar portion provided on these bobbins is tooth-cut, and both bobbins are interlocked by meshing by the tooth cutting. An automatic winding structure coil is provided.
【０００８】[0008]
内鉄形磁心の２辺に設けたそれぞれのボビンは歯車機構により互いに逆回転と なって連動するので、巻線の巻回に際し逆方向で同巻数のコイルが容易に得られ る。 Since each bobbin provided on the two sides of the inner iron core rotates in reverse by the gear mechanism and works together, a coil having the same number of turns in the opposite direction can be easily obtained when winding the winding.

つぎに本考案の実施例について図面を用いて詳細に説明する。 Next, an embodiment of the present invention will be described in detail with reference to the drawings.
【００１０】 図１は本考案の一実施例を示す側面図および上面図である。FIG. 1 is a side view and a top view showing an embodiment of the present invention.
【００１１】 同図において、１は内鉄形の鉄心で、例えばＩ字形のコア１１とＵ字形のコア １２とが密着されてロ字状の鉄心１を形成するものであり、Ｕ字形のコア１２の 円柱状または角の欠かれた両脚部にはそれぞれ円筒形のボビン２が装着されてい る。In the figure, reference numeral 1 denotes an inner iron core, for example, an I-shaped core 11 and a U-shaped core 12 are closely attached to each other to form a square-shaped iron core 1. A cylindrical bobbin 2 is attached to each of the twelve cylindrical legs or the two corners lacking the corners.
【００１２】 そして、ボビン２は例えば合成樹脂材からなるもので、その両端部の鍔部とな るフランジ部２１，２２の外周には歯車２１１，２２１が形成されて、コア１２ に装着時には左右のボビン２の歯車２１１および２２１がそれぞれ噛合い、片方 のボビン２を回転させると、他方のボビンも回転するように構成されており、そ れぞれのボビン２の中央部分には例えば円形フランジ２３が設けられて、巻回さ れる巻線の間を隔てて浮遊容量の減少が図られている。The bobbin 2 is made of, for example, a synthetic resin material, and gears 211 and 221 are formed on the outer circumferences of the flange portions 21 and 22 which are flanges at both ends thereof, and are left and right when mounted on the core 12. The gears 211 and 221 of the bobbin 2 are meshed with each other, and when one of the bobbins 2 is rotated, the other bobbin 2 is also rotated. 23 is provided to reduce the stray capacitance between the wound windings.
【００１３】 つぎにこのように構成された本実施例の作動を説明すると、図におけるボビン ２，２の例えばＡおよびＣの端部から巻線を開始して、ＢおよびＤの方向に巻回 していく。この場合、それぞれのボビン２，２は歯車にて噛合うため、回転方向 が逆向きとなって一組の逆方向の同巻数に巻回されたコイルが得られることにな る。したがって、ＡおよびＣ側を電源方向に結線し、ＢおよびＤ側に負荷を接続 すれば、両コイルに通ずる電流による磁界は鉄心１にて打消し合う事になり、鉄 心の飽和を防ぎ、インダクタンスが保持される。重畳される高周波のノイズ成分 は、両コイルとコンデンサを組合わせローパスフィルタで除去されノイズフィル タとして作動することになる。Next, the operation of the present embodiment configured as described above will be described. Starting from the ends of, for example, A and C of the bobbins 2 and 2 in the drawing, winding is started in the directions of B and D. I will do it. In this case, since the bobbins 2 and 2 mesh with each other by gears, the directions of rotation are opposite, and a set of coils wound in the same number of turns in the opposite direction is obtained. Therefore, if the A and C sides are connected in the power supply direction and the loads are connected to the B and D sides, the magnetic fields due to the currents flowing through both coils will cancel each other at the iron core 1, preventing saturation of the iron core, The inductance is retained. The superimposed high frequency noise component is removed by a low pass filter by combining both coils and a capacitor, and operates as a noise filter.
【００１４】 図２は本考案の他の実施例の構成を示す斜視図であり、両ボビン２０，２０を 逆方向に回転させる歯車付フランジ２５を一端のみとして他端は円形フランジ２ ６として形成したものである。FIG. 2 is a perspective view showing the configuration of another embodiment of the present invention, in which the geared flange 25 for rotating both bobbins 20, 20 in opposite directions is formed as one end and the other end is formed as a circular flange 26. It was done.
【００１５】 また、図３は図２におけるボビン２０をその回転軸に沿って縦割りした割ボビ ン２７を使用し、鉄心１０が分割できないロ字形の場合に対応できるようにした もので、２個の割ボビン２７を互いに合せて接着することにより、ボビンや歯車 が完成して、図２と同様に逆方向の一対の巻線が得られるものである。Further, FIG. 3 uses a split bobbin 27 obtained by vertically splitting the bobbin 20 in FIG. 2 along its rotation axis so that it can be applied to the case where the iron core 10 has a square shape which cannot be divided. A bobbin and a gear are completed by aligning and bonding the individual split bobbins 27 to each other, and a pair of windings in opposite directions can be obtained as in the case of FIG.
【００１６】 以上、本考案を上述の実施例によって説明したが、本考案の主旨の範囲内で、 例えば歯車付のフランジや巻線を分割するフランジをボビンに一個のみでなく多 数設けるように種々の変形が可能であり、これらの変形を本考案の範囲から排除 するものではない。The present invention has been described above with reference to the above-mentioned embodiments. However, within the scope of the present invention, for example, a bobbin may be provided with not only one flange but also a large number of flanges for splitting the winding. Various modifications are possible, and these modifications are not excluded from the scope of the present invention.
【００１７】[0017]
上述の実施例のように本考案によれば、内鉄形磁心の対向する２辺に回転自在 なボビンをそれぞれ設け、これらのボビンは歯車機構により連動するように構成 したので、巻線の巻回に際しては逆方向の同巻数のコイルが容易に得られて巻線 の手数が減じ、さらに巻線スペースが広いため重ね巻の層数が少なく浮遊容量の 小さいコイルが得られるという効果がある。 According to the present invention, as in the above-described embodiment, rotatable bobbins are provided on two opposite sides of the inner iron core, and these bobbins are configured to be interlocked by a gear mechanism. When the coil is wound, it is easy to obtain a coil with the same number of turns in the opposite direction, which reduces the number of windings, and since the winding space is large, there is the effect that the number of layers of overlapping windings is small and the stray capacitance is small.
