Abstract

Hochspannungssspule für einen Zündtransformator einer Zündanlage einer Brennkraftmaschine mit einem Spulenkörper, der etwa in Form eines Hohlzylinders mit geraden Seiten und abgerundeten Kanten ausgebildet ist. Der Spulenkörper weist Trennstege 3 auf, die Wicklungskammern 1 begrenzen und mit Kammerdurchbrüchen 4 versehen sind. Die Wicklung ist gruppenweise in die Wicklungskammern 1 gewickelt. Die Wicklungsgruppen 6 sind über Wickeldrahtübergänge miteinander verbunden, die durch die Kammerdurchbrüche 4 führen. Die Kammerdurchbrüche 4 sind von einer Stelle in Wicklungsrichtung am Anfang der Abrundung einer Spulenkörperkante ausgehend ausgebildet. High-voltage coil for an ignition transformer of an ignition system of an internal combustion engine with a bobbin, which is approximately in the form of a hollow cylinder with straight sides and rounded edges. The coil former has separating webs 3, which delimit winding chambers 1 and are provided with chamber openings 4. The winding is wound in groups in the winding chambers 1. The winding groups 6 are connected to one another via winding wire transitions which lead through the chamber openings 4. The chamber openings 4 are formed starting from a point in the winding direction at the beginning of the rounding off of a coil former edge.
