Abstract

Es wird eine Zündspule (10) einer Zündanlage einer Brennkraftmaschine vorgeschlagen. Die Zündspule (10) umfasst ein aus isolierendem Kunststoff gefertigtes Spulengehäuse (12), einen magnetisch wirksamen 1-Kern (14), der von einer ersten, mit einer Versorgungsspannung verbundenen Spulenwicklung (18) und einer zweiten, mit einem Hochspannungsanschluss verbundenen Spulenwicklung (22) umschlossen ist, sowie einen mit dem 1-Kern (14) einen magnetischen Kreis bildenden, die Anordnung aus der ersten (18) und der zweiten (22) Spulenwicklung umschließenden Umfangskem (26). Erfindungsgemäß ist zwischen dem Spulengehäuse (12) und dem Umfangskern (26) zumindest bereichsweise mindestens ein elektrisch leitfähiger Kunststoffabschnitt (28) angeordnet, der mit dem Umfangskern (26) elektrisch verbunden ist und im Wesentlichen luftspaltfrei an das Spulengehäuse (12) grenzt (Figur 2).
