本発明は、台形に巻いたコイルを数個組み合せて駆動コ
イルとするモータの該駆動コイル、或いは変成器等に使
用されるコイル等の偏平空芯のコイルに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drive coil of a motor in which several trapezoidally wound coils are combined as a drive coil, or a flat air-core coil such as a coil used in a transformer, etc. be.
従来のこの種の偏平空芯のコイルは、断面が円形の絶縁
被膜電線を所要の形状のコアに、所要のターン数捲回し
たものを用いるのが最も一般的であった0
しかしながらこのものは第1図に示すように、最も空隙
の少い捲回ができたとしても、導電体1が断面積の中で
占める占有率を高く取れないため所要ターン数に比して
、断面積が大きくなる欠点があった。Conventional flat air-core coils of this type most commonly use an insulated wire with a circular cross section wound around a core of the desired shape and the required number of turns. As shown in Figure 1, even if a winding with the fewest voids is possible, the cross-sectional area is large compared to the required number of turns because the conductor 1 cannot occupy a high proportion of the cross-sectional area. There was a drawback.
即ち、第1図において、絶縁N2を含む線材の半径をR
I、線材中の導電体の半径をR2とすると、断面積中線
材の占める断面積の率は3πR2”/6xバR12×1
00
−90.69%
となるが、これは理想的な値であって、実際には線材間
に空間を生じるため、これよりも低い値となってしまう
。That is, in FIG. 1, the radius of the wire including the insulation N2 is R.
I, if the radius of the conductor in the wire is R2, the ratio of the cross-sectional area occupied by the wire in the cross-sectional area is 3πR2"/6x Bar R12 x 1
00 -90.69%, which is an ideal value; in reality, spaces are created between the wires, so the value is lower than this.
そして、線材中の導電体2あ占積率は、使われる線材に
よって若干具なるが、例えば導電体2として0.17m
の直径の銅線を使用した時のポリウレ多ン被膜銅線の最
大仕上径が0.214mmであるため、占積率は69%
である。The space factor of the conductor 2 in the wire varies slightly depending on the wire used, but for example, the conductor 2 is 0.17 m
When using copper wire with a diameter of
It is.
従って、コイルの断面中で導電体2が占める面積率は、
理想的な場合でも
90.69%×69%#62%
となり、実際には50%程度となるのが普通で、最良で
も60%止まりであり、カセットレコードプレーヤ等に
使われるコイルの占積率も60%程度である。Therefore, the area ratio occupied by the conductor 2 in the cross section of the coil is:
Even in the ideal case, it is 90.69% x 69% #62%, but in reality it is usually around 50%, and at best it is only 60%, which is the space factor of the coil used in cassette record players etc. is also about 60%.
そのため、第2図に示すように、断面円形の絶縁被膜銅
線をロール機等で偏平に押しつぶし、これをコアに捲回
する方法も提案されている。Therefore, as shown in FIG. 2, a method has also been proposed in which an insulating coated copper wire with a circular cross section is flattened using a roll machine or the like and then wound around a core.
この場合も、線材の材料が絶縁被膜銅線であるので、線
材そのもの、占積率は変らず、従ってコイルとしての導
電体の占積率は70%以上にはなり得ない。In this case as well, since the material of the wire is an insulating coated copper wire, the space factor of the wire itself does not change, and therefore the space factor of the conductor as a coil cannot exceed 70%.
又、絶縁層を含めてロール等で圧延するので、断面の縦
横比率を大きくすると、絶縁層が破損して眉間短絡の原
因となるので、あまり偏平につぶすことはできず、しか
も偏平率を大きくしても、0.17n径の線材では絶縁
厚が0.022in程度あるので、絶縁層を含めた厚さ
に対し、導電体の厚みが小さくなって占積率が減少する
結果ともなるので好ましくない。In addition, since the insulating layer is rolled with rolls, etc., if the aspect ratio of the cross section is increased, the insulating layer will be damaged and cause a short circuit between the eyebrows. However, since the insulation thickness is about 0.022 inch for a wire with a diameter of 0.17 nm, the thickness of the conductor becomes smaller than the thickness including the insulation layer, which results in a decrease in the space factor, which is preferable. do not have.
更に、導電体の径がバラつくと、つぶされた線材中はそ
のバラつきが拡大されてバラつくので、捲回されたコイ
ル全体としてl〕が所定の中白に入らなくなってしまっ
たり、磁気回路の一部として使用されるコイルの場合に
は、部分的にコイルとマグネット間のギャップが増大す
ることとなって結果的には、磁気効率を低下させること
となってしまう。Furthermore, if the diameter of the conductor varies, this variation will be magnified and varied in the crushed wire, so that the entire wound coil may not fit within the specified center area, or the magnetic circuit may In the case of a coil used as a part of the magnet, the gap between the coil and the magnet increases in some areas, resulting in a decrease in magnetic efficiency.
又近時、薄い絶縁シート上に金属薄膜を張り付け、この
薄膜に所定のパターンを印刷し、又はホトレジスト処理
を行なった後エツチングして所定のコイル形状の金属薄
膜を残したプリントコイルを、このような絶縁シートを
所要枚数重ねて使用するものが提案されている。Recently, printed coils have been developed in which a metal thin film is pasted on a thin insulating sheet, a predetermined pattern is printed on this thin film, or a metal thin film is left in a predetermined coil shape by photoresist treatment and etching. A method has been proposed in which a required number of insulating sheets are stacked on top of each other.
しかしながらこのコイルは、前記のようにして形成され
るため、コイルとなる金属薄膜の中3が薄膜の厚さに対
して第4図に示すように大きな寸法を必要とするので、
絶縁シートの重積によっても、多くのターン数を必要と
するコイルには使用できなかった。However, since this coil is formed as described above, the middle part of the metal thin film that becomes the coil requires a large dimension compared to the thickness of the thin film, as shown in FIG.
Due to the stacking of insulating sheets, it could not be used for coils that required a large number of turns.
又、生産性を考慮した場合には絶縁シート4の厚さを0
.01n以下にすることは困難なので、占積率の向上は
望めない欠点が残っている。In addition, when considering productivity, the thickness of the insulating sheet 4 is set to 0.
.. Since it is difficult to reduce the thickness to 01n or less, there remains a drawback that an improvement in the space factor cannot be expected.
本発明は、従来のこのような欠点を除去し、占積率の向
上を計ると共に、コイルの外形を一定の寸法、形状とす
ることが可能で、プリントコイルよりも高電流を流すこ
とができ、また巻数を増すことができる高能率、高品質
の偏平空芯コイルを提供することである。The present invention eliminates these conventional drawbacks, improves the space factor, and makes it possible to make the outer shape of the coil constant in size and shape, allowing a higher current to flow than a printed coil. Another object of the present invention is to provide a high-efficiency, high-quality flat air-core coil that can increase the number of turns.
更に、本発明は、これを製造するための切断工程で発生
したパリ等による眉間短絡を除去する工程において、コ
イル層となる導電性の薄帯が腐蝕されるのを防止するこ
とをも目的とするものである。A further object of the present invention is to prevent corrosion of the conductive thin strip that becomes the coil layer in the process of removing glabellar short circuits caused by pars etc. that occur during the cutting process for manufacturing this. It is something to do.
即ち、本発明のコイルは、導電性の薄い中広の帯に、そ
の片面に絶縁層を、他面に接着剤層を設けてaFil薄
帯とし、これを所要形状のコアに巻き付けた後、これに
外圧を加えて密着され、これを所要厚さに切断し、絶縁
処理を行ったものである。That is, the coil of the present invention is made by forming an aFil ribbon by providing an insulating layer on one side and an adhesive layer on the other side of a conductive thin medium-wide band, and winding this around a core of a desired shape. This is then sealed by applying external pressure, cut to the required thickness, and then insulated.

Stress is applied between the wire 16 and the thin ribbon d, and the wire 16 is cut while moving back and forth.
切断効率を上げるため、3N薄帯dをガラス板等に接着
剤で固定し、同時に多数のワイヤを用いて切断する場合
もある。In order to increase cutting efficiency, the 3N thin ribbon d may be fixed to a glass plate or the like with an adhesive and simultaneously cut using a large number of wires.
第8.9.10工程は、前記切断後に、3層薄帯dに付
着した砥粒を洗浄する工程で、洗浄は3層薄帯dに悪影
響を及ぼさないトリクレン、グイフロン等を用いて超音
波洗浄機17で行い、乾燥はヒーター1Bで第5工程よ
り低温で加熱しながら熱風乾燥炉19を使用する。Step 8.9.10 is a step of cleaning the abrasive grains attached to the three-layer ribbon d after the cutting, and the cleaning is carried out using ultrasonic waves using Triclean, Guiflon, etc., which do not have a negative effect on the three-layer ribbon d. The washing machine 17 is used for drying, and the hot air drying oven 19 is used while heating at a lower temperature than the fifth step using the heater 1B.
第11工程は硝酸(HNO3)、塩化第2鉄(FeC1

う。The 12th and 13th steps are steps for removing the etching agent used in the previous step, and the cleaning is done by neutralizing the etching agent and then washing with water, or directly washing with water, and then drying with the heater 18.
This is carried out in a hot air drying oven 19 heated at the same temperature as in the 10th step.
次の第14.15工程は、切断端面の絶縁処理工程で、
エポキシ系又はポリアミド系を稀釈した槽20内に浸漬

。The next 14th and 15th steps are insulation treatment steps for the cut end surface.
It is immersed in a bath 20 in which epoxy or polyamide is diluted and dried in a hot air drying oven 19 heated by a heater 18.
最後に、第16エ程で、3層薄帯dの巻き初め、巻き終
りを引き出して端子とする工程である。Finally, in step 16, the beginning and end of the three-layer ribbon d are pulled out to form a terminal.
このようにして製造された本発明のコイルは、銅箔aが
絶縁剤層すで絶縁されると共に、接着剤層Cで密着状態
に接着されているので、銅箔aの占積率が大きく取れる
と共に、銅箔aの厚さは数μ程度に薄くできるので捲回
数も大きくできるものである。In the coil of the present invention manufactured in this way, the copper foil a is insulated by the insulating layer and is tightly bonded by the adhesive layer C, so the space factor of the copper foil a is large. In addition to being easy to remove, the thickness of the copper foil a can be reduced to about several micrometers, so the number of turns can be increased.
従って高アンペアターンが得られるばかりでなく、厚さ
形状を一定とした高能率、高品質が得られる。Therefore, not only a high ampere turn can be obtained, but also high efficiency and high quality with constant thickness and shape can be obtained.
しかも本発明のコイルは、その3N薄帯dが、銅箔aの
一面に絶縁剤層b、他面に接着剤層Cを形成されている
ため、第3工程、第4工程によって捲着間の密着と第5
工程による接着が行なうことができると共に、コア11
に巻き初める時に、接着剤Ncと絶縁剤層すの何れを内
側とするかによって、巻き初めは内側とした層が露出し
、巻き終りはその反対層が露出し、第10図に示すよう
に巻き初め、巻き終りとも銅箔aが露出することはない
。Moreover, in the coil of the present invention, since the 3N thin ribbon d has an insulating layer b formed on one side of the copper foil a and an adhesive layer C formed on the other side, the coil is wound between the winding layers in the third and fourth steps. close contact and the fifth
Adhesion can be performed through the process, and the core 11
Depending on whether the adhesive Nc or the insulating layer is on the inside, the inner layer will be exposed at the beginning of the winding, and the opposite layer will be exposed at the end of the winding, as shown in Figure 10. The copper foil a is never exposed at the beginning or end of winding.
そのため第11工程でエツチングを行う際には、このよ
うに銅箔aは巻き初め、巻き終りで露出していないので
、エツチングによる腐蝕作用は受けない。Therefore, when etching is performed in the eleventh step, since the copper foil a is not exposed at the beginning and end of winding, it is not affected by the corrosive effect of etching.
更に、第3.4工程で捲眉間に一部空隙が生じてこの空
隙にエツチング液が浸入しても、この部分の銅箔aは空
隙の片面が接着剤層Cで、他面が絶縁剤層すで被覆され
ているから、断線する危険は生じない。Furthermore, even if some gaps are created between the eyebrows in step 3.4 and the etching solution infiltrates these gaps, the copper foil a in this area will have an adhesive layer C on one side of the gap and an insulating layer on the other side. Since the wire is covered with layers, there is no risk of wire breakage.
尚、絶縁剤層すとして接着性のある絶縁剤を、又接着剤
層Cとして接着性のある絶縁剤を使用す0
ることにより、両者を同一の材料で行うことも可能であ
る。Incidentally, by using an adhesive insulating agent as the insulating layer and an adhesive insulating agent as the adhesive layer C, it is also possible to use the same material for both.
叙上のように、本発明の偏平空芯コイルは、占積率が高
く、高能率で高品質なものであるが銅箔等の導電性の薄
帯の一面を接着剤層、他面を絶縁剤層で被覆したので、
巻き初め、巻き終りの何れにおいても、導電性の薄帯は
保護され、エツチング工程で巻き初め、巻き終りが腐蝕
することはない。As mentioned above, the flat air-core coil of the present invention has a high space factor, high efficiency, and high quality. Since it is covered with an insulating layer,
The conductive ribbon is protected both at the beginning and end of the winding, and the etching process will not corrode the conductive ribbon at the beginning or end of the winding.
更に、捲回工程や成型、接着工程で、捲眉間に空隙を生
じ、エツチング工程でエツチング液が浸入しても、これ
に腐蝕されて断線する危険性に対しても保護され、製品
の歩留りを向上できる。Furthermore, even if a gap is created between the winding eyebrows during the winding process, molding, or bonding process, and the etching liquid infiltrates during the etching process, it is protected against the risk of corrosion and disconnection, which reduces product yield. You can improve.
そして、巻き初め、巻き終り部分を端子とする際にも、
この部分が腐蝕等の悪影響を受けていないので、その引
出し作業が容易に行えると共に絶縁剤層、接着剤層を除
去する作業も行い易く、特にこれ等の層がハンダ付けの
熱で熔解するような材質のものを使用すれば、その除去
作業も不要となる。Also, when using the beginning and end of winding as terminals,
Since this part is not affected by corrosion or other negative effects, it is easy to pull it out, and it is also easy to remove the insulating and adhesive layers, especially since these layers are likely to melt due to the heat of soldering. If a suitable material is used, there is no need to remove it.
