Abstract:

An exhaust gas oxygen sensor and electrical connector arrangement for use in connecting the sensor to an electronic device capable of utilizing an electrical signal produced by the sensor. The electrical connector arrangement eliminates both male and female electrical connectors required in prior sensor electrical connector arrangements. The new electrical connector arrangement provides a leak-proof connection between a cylindrically-shaped sensor member and a connector assembly including an elastomeric grommet, a plastic sleeve and a plastic spacer used to retain connector terminals within the sleeve for receipt of cooperating terminals on the exhaust gas sensor. The connector-assembly sleeve and the cylindrically-shaped member of the oxygen sensor cooperate to produce a positive latching action of the connector assembly to the exhaust gas sensor.
