【考案の詳細な説明】
本考案は内燃機関用点火装置に用いられる点火コイルの
構造に関し、特に点火コイル２次巻線の巻終り端と高圧
側コードとの接続部の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an ignition coil used in an ignition system for an internal combustion engine, and in particular to an improvement in the connection between the end of the secondary winding of the ignition coil and the high-voltage cord.
上記の点火コイルの２次巻線は、一般に０．０５〜０．

高圧側コードをハンダ付けしていた。The secondary winding of the above ignition coil is generally 0.05 to 0.0.
We use ultra-fine enamel coated wire of about 0.07 mm,
In order to draw out the end of the winding to the outside, conventionally a thick metal plate in the shape of a letter is fixed to the outer periphery of the coil with taping, and this metal plate is attached to the end of the winding of the secondary winding and the high voltage for external extraction. I had soldered the side cord.
しかしながら、このような従来の引出線接続構造では、
コイル組立に要する部品点数及び工数が増加するだけで

ハンダ付けされる巻線巻終り端とコイル外周との間に段
差が生ずる。However, in such a conventional leader line connection structure,
Not only does the number of parts and man-hours required for coil assembly increase, but due to the thickness of the metal plate, a step is created between the end of the winding soldered to the upper surface of the metal plate and the outer periphery of the coil.
このために金属板近くで巻終り端が断線しやすく、また
、段差部分には含浸剤が満足に充填されないため空隙が
できて、コロナ発生による絶縁破壊が生じやすいという
欠点があった。For this reason, the end of the winding is likely to break near the metal plate, and the stepped portions are not satisfactorily filled with impregnating agent, resulting in voids, which tend to cause dielectric breakdown due to corona generation.
本考案はこれらの欠点に鑑み、２次巻線の巻終り端と、
高圧側コードとの接続部の構造を改良した点火コイルを
提供したものである。In view of these shortcomings, the present invention has developed a winding end of the secondary winding,
