Abstract

Eine Zündspule (11) für Zündanlagen, insbesondere als Stabzündspule in Brennkraftmaschinen ist so auszugestalten, daß sie auch unter hohen thermischen Belastungen besonders betriebssicher ist.An ignition coil (11) for ignition systems, especially as Rod ignition coil in internal combustion engines is to be designed that they are special even under high thermal loads is reliable.

Dazu ist die Zündspule (11) so ausgebildet, daß ein Wicklungssatz (17) als eine erste Wärmequelle der Zündspule (11) in einem Hauptteil eines Gehäuses (19) der Zündspule (11) und in einem davon durch ein Trennelement (27) abgesetzten Gehäuseteil (28) eine Endstufe (31) der Zündspule (11) als eine zweite Wärmequelle angeordnet ist. Dadurch ist die Wärmebelastung der Endstufe (31) zur Verbesserung der Betriebssicherheit der Zündspule (11) abgesenkt.For this purpose, the ignition coil (11) is designed so that a Winding set (17) as a first heat source of the ignition coil (11) in a main part of a housing (19) of the ignition coil (11) and in one of them by a separating element (27) remote housing part (28) an output stage (31) Ignition coil (11) is arranged as a second heat source. As a result, the thermal load on the output stage (31) is Improving the operational safety of the ignition coil (11) lowered.

Die Zündspule (11) wird vorzugsweise im Automobilbau eingesetzt.
