Gas sensor, particularly for determining physical characteristics of message, has joining units that are integrated in contacting device

摘要

The gas sensor has joining units that are integrated in a contacting device (23), which is supported while joining sensor element and contacting device by their relative movement along a joining path extending between a joint starting and joint end position at a protective cap (21). An increased contact pressure is generated in the joint end position between contact surface and contact element compared to the joint starting position. The joining path of the joining unit is deflected from the sliding path of a protective sleeve (20) to a housing (11).
