Abstract

Ein Sauerstoffsensor 10 beinhaltet ein Sauerstofferfassungselement 20, das eine entlang der Achse verlaufende hohle Röhrenform annimmt. Das Sauerstofferfassungselement 20 weist ein geschlossenes vorderes Ende und ein geöffnetes hinteres Ende auf. Eine innere Elektrodenschicht 23 ist auf einer inneren Umfangsoberfläche 22 des Sauerstofferfassungselements 20 ausgebildet. Der Sensor 10 weist auch ein Anschlussglied 30 auf, das mit der inneren Elektrodenschicht 23 in Kontakt steht und in elektrischer Verbindung damit ist. Das Anschlussglied 30 weist Presskontaktbereiche 34c und 34d auf, die mit der inneren Umfangsoberfläche 22 des Sauerstofferfassungselements 20 in Presskontakt kommen, um das Anschlussglied 30 im Sauerstofferfassungselement 20 zu halten, sowie Leitungsbereiche 35b, die mit der inneren Elektrodenschicht 23 auf der inneren Umfangsoberfläche 22 des Sauerstofferfassungselements 20 in Presskontakt kommen und mit der inneren Elektrodenschicht 23 in elektrischer Verbindung stehen. Die Presskraft pro Einheitsfläche ist in den Leitungsbereichen 35b kleiner als in den Presskontaktbereichen 34c und 34d.
