In this case, the second contact means is arranged on the first contact means, so that an electrical contact connection is formed. The electrical supply line is electrically conductively connected to the second contact means.
Elektrische Kontaktverbindungen werden oftmals mit einem Stecker und einem Gegenstecker ausgeführt, an welchen ein erstes und ein zweites Kontaktmittel angeordnet sind. Dabei erleichtern Stecker und Gegenstecker die passende Anordnung des ersten und zweiten Kontaktmittels zueinander und erleichtern die Montage und Demontage im Fall lösbarer elektrischer Verbindungen. Oftmals führen Stecker und Gegenstecker eine mechanische Verbindung aus, während die Kontaktmittel für eine optimale elektrische Verbindung ausgelegt sind. Elektrische Kontaktverbindungen, die erschwerten Umwelteinflüssen ausgesetzt sind, wie z.B. im Außenbereich, in Feuchträumen oder im Kfz werden oftmals mittels abgedichteter Stecker ausgeführt.

Diese Einzeladerabdichtung besteht aus einer Bewehrung 9 in Form einer Me- tallhülse, die im Innen- und Außenbereich mit einer Dichtung 7 in Form eines dichtendenFigure 4 shows schematically a seal with reinforcement of the electrical supply line for a development of the device according to the invention. The sectional longitudinal view shows the electrical supply line 6 and a seal in the form of a single wire seal. This single wire seal consists of a reinforcement 9 in the form of a metal sleeve, which in the interior and exterior with a seal 7 in the form of a sealing
Kunststoffs beschichtet ist. Durch die Innen- und Außengeometrie des Kunststoffes wird sichergestellt, daß keine Umwelteinflüsse in den Innenbereich des Sensors gelangen. Diese Einzeladerabdichtung weist direkten mechanischen Kontakt zum Kabelschuh und zur Verriegelung 8 auf. Die Einzeladerabdichtung realisiert dadurch die gewünschte Zugent- lastung in Richtung 11. die Verriegelung 8 ist vorzugsweise so auszuführen, daß es möglich ist, im vormontierten Zustand die elektrische Zuleitung 6 mit Einzeladerabdichtung in das Sensorgehäuse einzuführen und die vormontierte Verriegelung 8 anschließend in ihre endgültige Position zu bringen, insbesondere in eine formschlüssige Verbindung einzurasten. Plastic is coated. The internal and external geometry of the plastic ensures that no environmental influences enter the interior of the sensor. This single wire seal has direct mechanical contact with the cable lug and the lock 8. The single core seal realizes the desired strain relief in the direction 11. The locking 8 is preferably to be designed so that it is possible to introduce the electrical supply line 6 with single core seal in the sensor housing in the preassembled state and then the pre-assembled lock 8 in its final position bring, in particular lock in a positive connection.
