Description

Zündkerze. Die Erfindung betrifft eine neue, leicht lösbare Befestigung der mittleren Elektrode in oder an dem Isolationskörper einer Zündkerze. Die stabförmige mittlere Elektrode ist in bekannter Weise in einer zentralen Bohrung des Isolationskörpers gelagert, in welcher Lage sie erfindungsgemäß dadurch festgehalten wird, daß ihr oberes Ende durch Pressung, Verschraubung o. dgl. mit einer aus einem weicheren Metall, wie z. B. Kupfer, bestehenden Kappe verbunden ist, die einen Gewindezapfen zum Anschließen des Zündkabels aufweist und die durch eine auf den Isolationskörper aufzuschraubende überwurfmutter dichtend auf den -Isolationskörper gepreßt wird.Spark plug. The invention relates to a new, easily detachable fastening the middle electrode in or on the insulation body of a spark plug. The rod-shaped middle electrode is in a known manner in a central bore of the insulation body stored, in which position it is held according to the invention that you upper end by pressing, screwing or the like. With one of a softer one Metal, such as B. copper, existing cap is connected, which has a threaded pin for connecting the ignition cable and which by one on the insulation body The union nut to be screwed on is pressed tightly onto the insulation body.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in einem Längsschnitt. Der in bekannter Weise in dem Zündkerzenkörper a, b befestigte Isolationskörper c ist an seinem oberen Ende mit Gewinde d versehen, auf das eine überwurfmutter e aufgeschraubt wird. Der in einer Bohrung des Isolationskörpers c geführte Elektrodenstift f ist durch Pressung, Verschraubung o. dgl. mit einer Kappe g verbunden, die durch die Mutter e auf den Isolationskörper c gepreßt wird, wobei die Kappe g zwecks Erzielung einer guten Dichtung unten bei g' etwas ausgehöhlt sein kann. Der Gewindezapfen g" der Kappe g dient in bekannter Weise zum Befestigen des Zündkabels, indem .er durch eine Bohrung der Mutter c nach oben durchtritt.The drawing shows an embodiment of the invention in a longitudinal section. The insulation body c, which is fastened in a known manner in the spark plug body a, b , is provided at its upper end with a thread d onto which a union nut e is screwed. The electrode pin f guided in a bore in the insulation body c is connected by pressing, screwing or the like to a cap g which is pressed onto the insulation body c by the nut e, the cap g at the bottom at g 'in order to achieve a good seal. something can be hollowed out. The threaded pin g ″ of the cap g is used in a known manner to fasten the ignition cable by passing upwards through a hole in the nut c.

Die Mutter e kann zweckmäßig mit Kühlrippen versehen sein, wie dies bei h gestrichelt angegeben ist.The nut e can expediently be provided with cooling fins, like this is indicated by dashed lines at h.
