Sensor for a motor vehicle
Various embodiments may include a sensor for a motor vehicle including an anode conductor, an anode sleeve connected to the anode conductor, an adapter sleeve, a housing, a connection between the housing and the adapter sleeve, and a cathode sleeve connected to the housing. The anode conductor is rigidly connected to the adapter sleeve by an electrical insulator. The anode sleeve and the cathode sleeve are arranged coaxially with respect to one another within the scope of the production tolerances.
1. A sensor for a motor vehicle, the sensor comprising:
a housing:
an adapter sleeve arranged in the housing;
an anode conductor arranged in the adapter sleeve;
wherein the anode conductor is rigidly connected to the adapter sleeve by an electrical insulator;
an electrically conductive anode sleeve connected to the anode conductor and extending beyond the housing in a longitudinal direction;
an electrically conductive cathode sleeve connected to the housing;
wherein the anode sleeve is arranged at least partially within the cathode sleeve; and
wherein the anode sleeve and the cathode sleeve are arranged coaxially with respect to one another within the scope of the production tolerances.
2. The sensor as claimed in claim 1 , wherein the adapter sleeve is welded to the housing.
3. The sensor as claimed in claim 1 , wherein the adapter sleeve, the anode conductor, and the insulator form an assembly physically distinct from the housing.
4. The sensor as claimed in claim 1 , wherein the adapter sleeve, the anode conductor, and the insulator are connected to one another by solder.
5. The sensor as claimed in claim 1 , wherein the adapter sleeve comprises a metal with a coefficient of thermal expansion corresponding to a coefficient of thermal expansion of the insulator within a predefined tolerance range.
6. The sensor as claimed in claim 1 , wherein the cathode sleeve includes, at a first end facing away from the housing, an internal diameter greater than or equal to an external diameter of the anode sleeve in an end region facing away from the housing.
