Description

  

  Zündkerze für     Brennkraftmasehinen.       Die Neuerung bezieht sich auf Zündker  zen für     Brennkraftmaschinen    mit einem vor  zugsweise keramischen Isolator, der in dem  Gehäuse der Kerze     mittels    eines in .dem Ge  häuse     befestigten    Ringes     gehalten    wird. Bis  her war es üblich, den Ring entweder in  das Gehäuse einzuschrauben oder durch     Um-          bördelung    des Gehäuserandes zu halten. Die  Neuerung besteht darin,     dass    der den Isolator       festhaltende    Ring mit dem Kerzengehäuse  verschweisst oder hart verlötet ist.  



  In der Zeichnung ist als     Ausführungsbei-          spiel    des Gegenstandes :der Neuerung eine  vollabgeschirmte Zündkerze im Schnitt dar  gestellt.     a    ist das     Gehäuse,der    Kerze, indem  ein keramischer     Isolator    b sitzt. Das Gehäuse  steht     über,das        anschlussseitige    Ende des Iso  lators vor und     isst    am Ende innen mit einem    Gewinde versehen, in :das eine Hülse c einge  schraubt ist, an welcher die     Abschirmteile     des zur Kerze geführten Zündkabels ange  schlossen werden können.

   Der Isolator b, der       in,dem    Gehäuse auf einem Absatz d aufsitzt,  wird darin von einem Ring e gehalten, der  mit dem Gehäuse durch Schweissen oder Hart  löten     verbunden    ist.



  Spark plug for internal combustion engines. The innovation relates to Zündker zen for internal combustion engines with a preferably ceramic insulator before, which is held in the housing of the candle by means of a ring attached in .dem Ge housing. Until now, it was common to either screw the ring into the housing or to hold it by flanging the edge of the housing. The innovation is that the ring holding the insulator is welded or hard-soldered to the plug housing.



  In the drawing, the following is an exemplary embodiment of the subject: the innovation is a fully shielded spark plug in section. a is the housing, the candle, in which a ceramic insulator b sits. The housing protrudes, the connection-side end of the isolator and eats at the end provided with a thread inside: a sleeve c is screwed to which the shielding parts of the ignition cable leading to the plug can be connected.

   The insulator b, which sits on a shoulder d in the housing, is held therein by a ring e which is connected to the housing by welding or hard soldering.
