Terminal member for 02 sensor

摘要

A terminal member (120) for an electrolyte sensor (24) having a first diameter section (122) separated from a second diameter section (124) by a shoulder (126). A stepped axial bore (138) extends from a second end (134) forward a first end (132). First and second passages (128 and 130) extend from the first end (132) to the second end (134). An axial slot (136) extends through the second diameter (124) to the stepped axial bore (138). First and second grooves (156 and 158) located on the periphery of the first diameter (122) extend to a first radial slot (160). A second radial slot (162) is offset from the first radial slot (160). The first and second radial slots (160 and 162) position terminals (164 and 164') connected to a heater member (92) located in bore (138) while first and second contact rings (142 and 144) are located on shoulder (126) and (140) to provide isolation for electrical paths between an external surface (80) and internal surface (82) of an electrolyte sensor (24).
