本発明は、コアレスモーフ、トランス等のコイル、或い
はカートリッジの発電コイル等のコイルの製造方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a coil such as a coil for a coreless morph, a transformer, or a generator coil for a cartridge.
従来のこの種のコイルは、エナメル銅線等の絶縁処理が
施されている断面円形の電線を巻枠にテンションを与え
ながら所要のターン数巻き取って製作したものである。Conventional coils of this type are manufactured by winding an insulated wire such as enamelled copper wire with a circular cross section while applying tension to a winding frame for the required number of turns.
このように、電線には一定のテンションが加わって巻取
られるために、線材自体に多少の伸びが発生し、為にコ
イルに流れる電流によって断線する等の事故の原因とな
っていた。In this way, since the wire is wound under a certain tension, the wire itself stretches to some extent, which causes accidents such as wire breakage due to the current flowing through the coil.
又、電線が断面円形であるため、巻かれた電線間に空間
を生じるため、一定限度以上に密度を上げることはでき
なかった。Further, since the electric wire has a circular cross section, spaces are created between the wound electric wires, so it is impossible to increase the density beyond a certain limit.
更には、絶縁材のコーティング不良、例えばピンホール
の発生等、及び線材の傷等の発生によって、断線したり
、層間短絡の原因となる等の欠点を持っていた。Furthermore, there have been other drawbacks, such as poor coating of the insulating material, such as pinholes, and scratches on the wire, which can cause wire breakage or interlayer short circuits.
本発明は、導電性の金属箔と、絶縁性の熱可塑性フィル

ある。By forming a coil with conductive metal foil and an insulating thermoplastic film, the present invention increases the coil density and has high insulation properties, while eliminating the drawbacks of the conventional coil. Moreover, the present invention provides a method of manufacturing a coil that can extremely easily manufacture coils with uniform characteristics.
以下、本発明の実施例を、図面について説明する。Embodiments of the present invention will be described below with reference to the drawings.

に熱可塑性フィルム１と金属箔２の重合体を、必要なテ
ンションを与えながら巻取り、断面形状が所要コイルの
形状で巻数が所要のターン数の筒状捲回体４を形成する
。A thermoplastic film 1 having an insulating property such as polyethylene and a metal foil 2 having a conductive property such as aluminum foil are polymerized, and the starting end thereof is fixed to a winding frame 3 whose cross section has the same shape as the air core of the coil. Then, the polymer of thermoplastic film 1 and metal foil 2 is wound on the winding frame 3 to the required number of turns as a coil while applying the necessary tension, so that the cross-sectional shape is the required coil shape and the number of turns is the required number of turns. Several cylindrical wound bodies 4 are formed.
この筒状捲回体４を、コイルの使用場所の空間、或いは
電流等を考慮して、所要の厚さｔに輪切り状に切断して
コイル素材５とする。This cylindrical wound body 4 is cut into rings with a required thickness t, taking into consideration the space where the coil is used, the current, etc., to obtain the coil material 5.
この時点では、コイル素材５の切断端面ば、金属７ｉＪ
２に切断によるパリ等が発生しており、これ等が接触し
合って眉間短絡があるために、必要なターン数は得られ
ていない。At this point, the cut end surface of the coil material 5 is metal 7iJ.
In No. 2, there are cracks caused by cutting, and because these parts come into contact with each other and cause a short circuit between the eyebrows, the required number of turns cannot be obtained.
次に、このコイル素材５を、金属箔２に対してのみエツ
チング作用をし、熱可塑性フィルム１に対しては何の作
用もしないエツチング液内に必要な時間浸漬する。Next, the coil material 5 is immersed in an etching solution that etches only the metal foil 2 but does not have any effect on the thermoplastic film 1 for a necessary period of time.
この浸漬によって金属箔２は切断ハリ等が除かれて眉間
短絡が解除されるだけでなく、第３図に示すように、金
属箔２の切断端面もエツチングされて熱可塑性フィルム
Ｊの切断端面よりも凹んだ状態となる。This immersion not only removes the cutting stiffness of the metal foil 2 and eliminates the short circuit between the eyebrows, but also etches the cut end surface of the metal foil 2 so that it is closer to the cut end surface of the thermoplastic film J, as shown in FIG. is also in a depressed state.
このような状態となった時にコイル累月５を工・ノチン
ダ液より取出し、水洗、中和液の浸漬等の工程によって
エツチング作用を停止し、熱風乾燥等の乾燥処理によっ
てこれを乾燥し、各層の金属Ｍ２は熱可塑性フィルム１
で絶縁された状態となる。When this condition is reached, the coil 5 is taken out from the solution, washed with water, immersed in a neutralizing solution, etc. to stop the etching action, and then dried by hot air drying or other drying process to remove each layer. metal M2 is thermoplastic film 1
becomes insulated.
更に、乾燥を終ったコイル素材５は、赤外線炉等で熱可
塑性フィルム１の軟化温度以上に加熱を行うものである
。Further, the dried coil material 5 is heated to a temperature higher than the softening temperature of the thermoplastic film 1 using an infrared oven or the like.
この加熱は、熱可塑性フィルムＩの切断端面に赤外線等
の加熱力が最初に作用するため、この部分が先づ軟化温
度に達して熱可塑性フィルム１の収縮作用が始まり、第
４図に示すようにこの収縮作用によって金属Ｔ３２の端
面ば熱可塑性フィルム１で絶縁被覆されることとなり、
この状態となった処で加熱炉から取り出され、コイルが
完成する。In this heating, heating power such as infrared rays is first applied to the cut end face of the thermoplastic film I, so this part first reaches the softening temperature and the thermoplastic film 1 begins to shrink, as shown in Figure 4. Due to this shrinkage effect, the end face of the metal T32 is insulated and coated with the thermoplastic film 1,
Once this state has been reached, the coil is removed from the heating furnace and the coil is completed.
このコイルは、端面も熱可塑性フィルム１の収縮で絶縁
されるので、この端面に導電性物質が接触しても短絡す
る危険性のない、完全に絶縁されたコイルとなるもので
ある。Since the end faces of this coil are also insulated by shrinkage of the thermoplastic film 1, there is no risk of short circuiting even if a conductive substance comes into contact with the end faces, resulting in a completely insulated coil.
そして、このコイルは断面偏平な金属箔２を使用するた
めに無駄な空間がなく、コイル断面の有９ＪＪ利用率が
高められ、金属箔２、熱可塑性フィルム１の厚さを薄く
することによってコイル密度を」二げることができる。Since this coil uses metal foil 2 with a flat cross section, there is no wasted space, and the utilization rate of the coil cross section is increased.By reducing the thickness of metal foil 2 and thermoplastic film 1, the coil Density can be increased.
しかも、金属部分の重量を少くすることができるからコ
イルの軽量化も可能で、絶縁塗料で絶縁した電線のよう
に絶縁不良による眉間短絡や、断線の危険性のないコイ
ルが得られる。Furthermore, since the weight of the metal parts can be reduced, the weight of the coil can be reduced, and a coil can be obtained that does not have the risk of glabellar short circuits or disconnections due to poor insulation, unlike electric wires insulated with insulating paint.
本発明のコイルは、コアレスモーフ、トランスのコイル
、カートリッジの発電コイル等電流の少ないコイルとし
て好適のものである。The coil of the present invention is suitable as a coil with a small current such as a coreless morph, a transformer coil, a cartridge generator coil, etc.
本発明は、叙上のように、金属箔と熱可塑性フィルムを
重合、捲回して筒状１＠回体を形成し、これを所要中に
輪切り状に裁断してコイル素材を形成するので、同時に
多数のコイル素材が簡単に製造できる。As described above, in the present invention, a metal foil and a thermoplastic film are polymerized and wound to form a cylindrical 1@wound body, and this is cut into round slices as required to form a coil material. A large number of coil materials can be easily manufactured at the same time.

が短時間に、月つ容易に製造できるものである。This is then subjected to the steps of etching, neutralization, and heating to remove short circuits between the eyebrows due to cutting edges, etc., and to insulate the end surfaces. It is not necessary to perform the process for each coil material, and many processes can be performed at the same time, so a large number of coils can be easily manufactured in a short period of time.
