があり、品質の点でも劣るものとなつていた。 With this manufacturing method, it takes time and effort to position the plate terminals 7 and 8, resulting in poor productivity.
Moreover, before the adhesive hardens, the plate terminal 7,
There was a drawback that the protrusion amount changed when the 8 moved, and the quality was also inferior.
本発明は以上のような従来の欠点を除去しよう
とするものである。 The present invention seeks to eliminate the above-mentioned drawbacks of the prior art.
以下、本発明を一実施例の図面第４図〜第６図

れている。 That is, the present invention uses plate-shaped terminals 7 and 8 as shown in FIG. A V-shaped notch 14 is formed according to the amount of protrusion of the plate terminals 7 and 8 as shown in FIG.
3 is assembled onto the collar 2 of the drum-shaped core 1 arranged in a straight line. At this time, the adhesive is transferred onto the surfaces of the hoop material 13 where the plate-shaped terminals 7 and 8 are joined to the terminal attachment grooves 5 and 6 by a stamp method using a rubber stamp or the like.
