Exhaust sensor with removable electrical connection.

摘要

Disclosed is an exhaust oxygen sensor (30) including a component (40,42) requiring electricity to operate such as a heater or oxygen electrode. A first electrical terminal (50) is provided in electrical contact with the component (40,42) and has at least one male prong (54). A second electrical terminal (60) in electrical contact with a wire (62) for delivering electrical power from an external source is also provided. The second electrical terminal (60) has at least one female connector receptacle (56,58). The male prong (54) and the female receptacle (56,58) are constructed and arranged so at least one of the first and second electrical terminals is removable with respect to the other terminal. In one embodiment of the invention, the sensor may include a threaded nut slidably received over a tubular housing, constructed and arranged to be threaded onto a threaded exhaust manifold boss without rotating the housing.
