发明名称 Gas measurement probe, especially to determine gas content in exhaust gas of internal combustion engines; has spring-biased sensor that moves under pressure
摘要 The probe has a contact component carrier with two half-shells (9,10) held together by a spring element (1) that allows insertion of sensor, but then is biased to hold half-shells against contact points (21-24). The probe has a contact component carrier at the connector end (2) of an axially movable sensor (3) built into a tubular protective sleeve (8). The contact carrier comprises two opposing, externally symmetrical half-shells held together by a spring element. The spring element is arranged such that, in a first tensioning stage, if the contact carrier is to be premounted on the end of the sensor, the spring exerts only a small clamping force on the half-shells, and the sensor can still be easily inserted between the two shells. In a second tensioning stage, the spring presses through the inner wall of the protective sleeve (8) with a stronger force, from all sides, against the half-shells and presses these against the contact points.
