とができ、絶縁破壊が生ずることのない点火コイ
ル構造に関する。[Detailed description of the invention] This invention facilitates wiring during installation and molding during manufacturing, makes the mold coating uniform, and allows complete and economical varnish impregnation, and prevents dielectric breakdown. Regarding the ignition coil structure that does not occur.
この種の点火コイル構造として、近時はモール
ド製品が主流を占めている。 Molded products have recently become the mainstream of this type of ignition coil structure.
上記モールド製品にあつてはモールド被膜から
所要のリード線を引き出す必要があり、本考案は
その一本又は２本をターミナル端子として取付片
と一体にして取付け時の配線の便宜を図り、さら
にモールド被膜の均一化とワニス含浸の完全化を
図つたことを特徴とするものである。 In the case of the above molded products, it is necessary to draw out the required lead wires from the mold coating, and the present invention integrates one or two of them with the mounting piece as a terminal terminal to facilitate wiring during installation. It is characterized by a uniform coating and complete varnish impregnation.
上記モールド被膜の構造はコイル及びコアーを
モールド型枠内の中間位置に安定支持したのち、
その全周面にモールド成形材を注入するものであ
るが、従来、型枠内にコイル及びコアーを安定支
持する作業に手数を要し、安定支持が不完全で、
しかもコイルに凹凸があるとモールド被膜に肉薄
部が生じ、絶縁破壊が生ずる欠点があつた。 The structure of the mold coating described above is such that after stably supporting the coil and core at an intermediate position within the mold frame,
Molding material is injected into the entire circumference of the coil, but in the past, it took a lot of work to stably support the coil and core within the mold, and stable support was incomplete.
Moreover, when the coil has irregularities, thin parts are formed in the mold coating, resulting in dielectric breakdown.
本考案では上記欠点を除去するため、底部が閉
塞され、さらに適位置に取付片を有するコイルカ
ツプが使用される。 In order to eliminate the above-mentioned drawbacks, the present invention uses a coil cup with a closed bottom and an attachment piece at a suitable position.

てもワニスが内部に浸透せずそのほとんどが垂れ
落ち、それらは加熱乾燥時にも同様であり、数回
にわたりワニス含浸を行わなければならず、手数
を要するとともにワニスが無駄になる欠点があつ
た。 In addition, as with the conventional varnish impregnation, if the coil and core are bare, the varnish will not penetrate into the varnish even if it is immersed in the varnish, and most of it will drip out, and the same will happen during heating and drying. The varnish impregnation process has to be carried out several times, which is time-consuming and wastes the varnish.
本考案では上記コイルカツプによつて完全なワ
ニス含浸を行うことができ、しかもワニスの滞留
