この発明は回路しゃ断器などに使用されるコイルの製造
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a coil used in a circuit breaker or the like.
第１図に示されているような回路しゃ断器においては、
電磁引き外し機構（１）のコイル（２）に大電流が流れ
ると、その作用によって、可動接点（３）が、固定接点
（４）から離れて電流が遮断されるようになっている。In a circuit breaker like the one shown in Figure 1,
When a large current flows through the coil (2) of the electromagnetic tripping mechanism (1), the movable contact (3) moves away from the fixed contact (4) and the current is interrupted.
このような回路しゃ断器のコイル（２）は。The coil (2) of such a circuit breaker is.
従来、第２図のように、断面矩形の線導体を螺旋状に巻
回することによって構成されていたため、寸法が不正確

固定鉄心に組み込むときに該固定鉄心と上記巻始端面お
よび巻終端面との間にそれぞれ隙間が生じ、その隙間分
だけ高さ寸法Ｈが大きくなる欠点があった。Conventionally, as shown in Fig. 2, wire conductors with a rectangular cross section were wound spirally to form a structure, so the dimensions tended to be inaccurate, and the winding start and end surfaces were not aligned with the axis. When this coil (2) is assembled into a U-shaped fixed core, a gap is created between the fixed core and the winding start end surface and the winding end surface, and the height is increased by the amount of the gap. There was a drawback that the length H became large.
この発明は従来の欠点を改善するため罠なされたもので
、上記欠点のないコイルの製造方法を提供することを目
的としている。The present invention has been made to overcome the drawbacks of the prior art, and its object is to provide a method for manufacturing a coil that does not have the above-mentioned drawbacks.

から直角方向に延びる延設部とを有する階段状の線導体
において、その２つの延設部を、互に反対方向へ円弧状
に湾曲させながら折シ曲げる点にある。That is, the feature of the method of the present invention is that in a stepped wire conductor having a vertical portion, an extending portion extending perpendicularly from the upper end of the vertical portion, and an extending portion extending perpendicularly from the lower end of the vertical portion, The point is that the two extending portions are bent while curving in an arc shape in opposite directions.
以下、この発明の実施例を図面にしたがって説明する。Embodiments of the present invention will be described below with reference to the drawings.
まず、第３図のような階段状の線導体を平板から打ち抜

ながら折り曲げ、つづいて、他の延設部にを反Ａ方向に
円弧状に湾曲させながら折ル曲げる。これによシ、第５
図のようなコイル（２）が製作される。この方法によれ
ば、巻き径の小さなコイル（２）を製作する場合でも、
作業性がきわめてよい。First, a stepped wire conductor as shown in Figure 3 is punched out from a flat plate. In this case, there is a constant distance in the vertical direction between the extending part (support) extending perpendicularly from the upper end of the vertical part (213) and the extending part (23) extending perpendicularly from the lower end of the vertical part (21). Next, as shown in Fig. 4, for example, the extension part is bent in an arc shape in the direction of arrow A, and then the other extension part is bent in the opposite direction of arrow A. Bend it while curving it into an arc.
A coil (2) as shown in the figure is manufactured. According to this method, even when manufacturing a coil (2) with a small winding diameter,
Workability is extremely good.

used for. In this case, two arc-shaped extensions (2)
■) all extend in the direction perpendicular to the vertical part (21+), so the winding start end surface and winding end surface are parallel. Therefore, the U-shaped fixed core (5) and the coil (2) There is no gap between the winding start end surface and the winding end surface. In FIG. 4, (6) is a lead wire.
以上の説明から明らかなように、この発明によれば、寸
法の正確でかつ組み付は時の占有面積の小さなコイルを
容易に製造できる。とくに、巻き径の小さいコイルの場
合でも、巻きピッチを正確にとれる利点がある。As is clear from the above description, according to the present invention, it is possible to easily manufacture a coil that has accurate dimensions and occupies a small area when assembled. In particular, even in the case of a coil with a small winding diameter, there is an advantage that the winding pitch can be set accurately.
