【考案の詳細な説明】
本考案はコイルボビンに改良を加えて巻線幅を変えても
吸収でき、しかも組立ても容易で放熱性にも優れ、さら
にコイル間の絶縁性も保てるように構成したノイズフィ
ルターに関するものである。[Detailed description of the invention] This invention has been developed to improve the coil bobbin so that it can absorb noise even if the winding width is changed, is easy to assemble, has excellent heat dissipation, and maintains insulation between the coils. It's about filters.
従来におけるノイズフィルターに用いられるコイルボビ
ンとしては、第1図に示すように両端に鍔1を備えたコ
イルボビン2を用いていた。As a coil bobbin used in a conventional noise filter, a coil bobbin 2 having flanges 1 at both ends as shown in FIG. 1 has been used.
このようなコイルボビン2では巻線幅を変える場合には
異なる寸法のコイルボビン2を用いる必要があり、この
点で品種が多くなれば品種骨のコイルボビンが必要とな
りきわめて不経済となり、さらにコイルボビン2に巻回
したコイルの絶縁についてもコイル外周にテープを巻付
けたりしなければならず、生産性、材料コスト面で不利
になるものであった。In such a coil bobbin 2, when changing the winding width, it is necessary to use a coil bobbin 2 of a different size.In this point, as the number of varieties increases, coil bobbins of different types are required, which becomes extremely uneconomical. In order to insulate the turned coil, it was necessary to wrap tape around the outer circumference of the coil, which was disadvantageous in terms of productivity and material costs.
このようなことから、最近では第2図に示すように内筒
3と外筒4を一体に形成した2つのボビン構成体5,6
を作成し、一方のボビン構成体5の内筒3に他方のボビ
ン構成体6の内筒3がはまりこみ、ボビン構成体5の外

うにし、ボビン構成体5に合致するようなボビンレスコ
イルを作成し、このコイルをボビン構成体5に装着した
後、ボビン構成体6を組込んでコイルを密閉するような
ものも開発されている。For this reason, recently two bobbin structures 5 and 6 have been developed in which the inner cylinder 3 and the outer cylinder 4 are integrally formed, as shown in FIG.
The inner cylinder 3 of the other bobbin structure 6 is fitted into the inner cylinder 3 of one bobbin structure 5, and the outer cylinder 4 of the other bobbin structure 6 is butted against the outer cylinder 4 of the bobbin structure 5. A system has also been developed in which a bobbinless coil is created that matches the bobbin structure 5, and after this coil is attached to the bobbin structure 5, a bobbin structure 6 is incorporated and the coil is sealed. ing.
ところが上記構成においては、ボビン構成体5゜6とコ
イルの寸法が所定値に製作されないと、コイルの装着が
簡単かつ確実に行なうことができず、きわめて作業性が
悪く、実用性に乏しいものであった。However, in the above configuration, unless the dimensions of the bobbin component 5.6 and the coil are manufactured to predetermined values, the coil cannot be installed easily and reliably, resulting in extremely poor workability and lack of practicality. there were.
またコイルが完全密閉されているため絶縁性は優れてい
るが、コイルに発生するジュール熱が蓄積されて高温に
なり、コイルの寿命に悪影響を及ぼすなどの欠点をもち
、品質面でも十分満足できないものであった。Also, since the coil is completely sealed, the insulation is excellent, but the Joule heat generated in the coil accumulates and becomes high temperature, which has a negative effect on the lifespan of the coil, making it unsatisfactory in terms of quality. It was something.
本考案は以上のような従来の欠点を除去するものである
。The present invention eliminates the above-mentioned drawbacks of the prior art.
以下、本考案の実施例を図面第3図〜第5図により説明

されている。This bobbin structure 10.11 has a flange 13 at one end as shown in FIG. A cover 15 is provided to cover one outer peripheral surface of the coils 8 and 9.
しかも一方のボビン構成体10の巻芯部14aは、他の
ボビン構成体11の巻芯部14bより大きく構成されこ
の巻芯部14bが巻芯部14a内にはまりこむように構
成され、またボビン構成体11のカバー15 bはボビ
ン構成体10のカバー153の外側に重なり合うように
構成されている。Moreover, the winding core part 14a of one bobbin structure 10 is configured to be larger than the winding core part 14b of the other bobbin structure 11, and this winding core part 14b is configured to fit into the winding core part 14a, and the bobbin structure The cover 15b of the body 11 is configured to overlap the outside of the cover 153 of the bobbin structure 10.
このような構成で第4図に示すようにボビンレスとして

外周および゛ボビン構成体10のカバー15a上に重ね
る。With such a configuration, as shown in FIG.
4a, press one side of the outer periphery of the coils 8, 9 with the cover 15a, and then insert the winding core 14b of the bobbin structure 1 into the center hole of the coils 8, 9 and the winding core 14 of the bobbin structure.
a and overlap the cover 15b on the outer periphery of the coils 8 and 9 and the cover 15a of the bobbin structure 10.
このように組立てたものを第3図に示すよう磁心7に組
込む。The thus assembled product is assembled into the magnetic core 7 as shown in FIG.
このときコイル8,9の対向面にカバー15を位置させ
、互いにコイル8,9間の絶縁性を保つように構成する
。At this time, a cover 15 is placed on opposing surfaces of the coils 8 and 9, so as to maintain insulation between the coils 8 and 9.
以上のように本考案のノイズフィルターは構成されるた
め、ボビン構成体へのコイルの組込みはきわめて簡単か
つ確実に行なえ、組立てにおける生産性は著しく向上し
、しかもコイル間の絶縁はカバーで十分に行なえる。Since the noise filter of the present invention is constructed as described above, the coils can be assembled into the bobbin component extremely easily and reliably, and the productivity during assembly is significantly improved.Moreover, the insulation between the coils is sufficient with the cover. I can do it.
また、ボビン構成体はコイルの巻幅方向に対して自由に
調整できるため、品種の異なるノイズフルターにも利用
でき、ボビンの標準化が計れることになり、この点でも
きわめて合理化が計れることになる。In addition, since the bobbin structure can be freely adjusted in the direction of the winding width of the coil, it can be used for noise filters of different types, allowing for standardization of bobbins, and in this respect, it can be extremely streamlined.
さらにカバーはコイルの一側面のみを被うため一般的な

イルの外周を押えて組立時のコイルのばらけといったこ
とも阻止できるなどの利点をもち、実用的価値の大なる
ものである。Furthermore, since the cover covers only one side of the coil, there are fewer windings than in general noise filters, and because thin wire is used as the coil, Joule heat is generated by applying current and the temperature rises rapidly. It has great practical value as it has excellent heat dissipation properties, can extend the life of the coil, and can also hold down the outer circumference of the coil to prevent the coil from coming apart during assembly. .
