Abstract (en)
[origin: EP0565964A2] A high-voltage coil for an emission transformer of an ignition system of an internal-combustion engine, having a coil former which is constructed approximately in the form of a hollow cylinder with straight sides and rounded edges. The coil former has separating webs 3 which bound the winding chambers 1 and are provided with chamber perforations 4. The winding is wound in groups in the winding chambers 1. The winding groups 6 are connected to one another via winding wire junctions which lead through the chamber perforations 4. The chamber perforations 4 are constructed starting from a point in the winding direction at the start of the curvature of an edge of the coil former. <IMAGE>
