イミド皮膜の銅線を適用した場合でも極めて短かい時間
でコイルのターン間絶縁が損われるという欠点があった
。Therefore, synthetic resin enamel coatings (21 types are usually selected) that are formed depending on the operating temperature of electrical equipment coils.Synthetic resin enamel coatings +1+ can withstand mechanical external forces during coil manufacturing. , not easily damaged;
It also has excellent insulation performance. On the other hand, in terms of heat resistance, it has limitations because it is an organic substance. For example, s o O'C
Even when polyesterimide-coated copper wire is used in coils used at temperatures exceeding
この発明は上記欠点を解消することを目的とし、以下に
述べる優れた銅又は銅合金からなる絶縁導体を提供する
ものである。The present invention aims to eliminate the above-mentioned drawbacks and provides an insulated conductor made of excellent copper or copper alloy as described below.

１１は。Hereinafter, in one embodiment of the present invention shown in FIG. 2, a copper oxide layer, a cupric oxide layer, or a composite of both is formed, and this copper oxide layer is an electrically insulating material. be. That is, in the embodiment of the present invention, an oxide layer (3) is forcibly formed on the outer surface of the conductor substrate il+, and by making this an insulating layer, the edge of the turn jMI P3 of the coil is Obtainable. Conductor base made of copper or copper alloy +
11 is.
空気中での強熱またはアルカリ性薬品などの処理を得て

の良導体であるのに比べて。A forged layer (3) having a thickness of microns or more can be generated by treatment with intense heat in air or alkaline chemicals. Compared to the base metal, this oxide layer +31 is a good conductor of electricity.
著しく電気抵抗が高く、電気絶縁性である。これは銅線

上の絶縁皮膜は、耐電圧特性よりもむしろ耐熱性（いわ
ゆる耐パー／アウト特性）が必要である。It has extremely high electrical resistance and is electrically insulating. This is because the copper wire is used for low voltage, extremely low inter-turn voltage, and coils that carry large currents, so the insulation film on the copper wire has heat resistance (rather than voltage resistance). So-called par/out resistance characteristics) are required.
この様な用途に対しては前記の如く銅の酸化−１３）を
有する導体の絶縁性能と耐熱性は最適である。For such uses, the insulation performance and heat resistance of a conductor having copper oxidation (13) as described above is optimal.

装置コイルなど。Applications to which the present invention can be applied include, for example, coils for automobile engine starting motors, generator coils for charging automobile storage batteries, coils for motorcycle engine starting motors, and lighting device coils for motorcycles.
その用途は広い。Its uses are wide.
以上の様にこの発明では銅又は銅合金からなる導体素地
の表向に、−気絶縁牲を有する銅の酸化層を形成するよ
うにしているので、絶縁性と耐熱性を兼ね備えた絶縁導
体を極めて安価に提供することができる。As described above, in this invention, a copper oxide layer having gas-insulating properties is formed on the surface of a conductor base made of copper or a copper alloy, so an insulated conductor having both insulation and heat resistance can be obtained. It can be provided at an extremely low cost.
