Abstract

Es wird eine Stabzündspule für eine Zündanlage, insbesondere zum Einsatz bei einer Brennkraftmaschine eines Kraftfahrzeuges, vorgeschlagen, welche einen Spulenkörper (10) und eine im Wesentlichen zylindrische Gehäusewandung (12) aufweist. Zur Aufnahme des Anschlussbolzens (14) einer Zündkerze (16) ist hochspannungsseitig ein Kontaktelement (18) angeordnet, welches ein elastisches Dämpfungselement (20) aufweist. Das elastische Dämpfungselement (20) ist in einer Ausnehmung (22) im Kontaktelement (18) in direktem Kontakt zum Anschlussbolzen (14) der Zündkerze (16) angeordnet, und das Kontaktelement (18) kontaktiert den Anschlussbolzen (14) der Zündkerze (16) zumindest teilweise umfangsseitig (Figur 1).

It is proposed a pencil ignition coil for an ignition system, in particular for use in an internal combustion engine of a motor vehicle, which has a bobbin (10) and a substantially cylindrical housing wall (12). For receiving the connecting bolt (14) of a spark plug (16), a contact element (18) is arranged on the high voltage side, which has an elastic damping element (20). The elastic damping element (20) is arranged in a recess (22) in the contact element (18) in direct contact with the connection bolt (14) of the spark plug (16), and the contact element (18) contacts the connection bolt (14) of the spark plug (16). at least partially circumferentially (Figure 1).
