Claims

[Scope of utility model registration request]

(1) A rod-shaped thick film element with a sensitive part provided at one end is inserted into and fixed to a ceramic support body having a flange part, and this ceramic support body is surrounded by a metal housing and crimped and fixed at the flange part. An oxygen sensor characterized in that a membrane element is fixed to a ceramic support by glass sealing in a region where thermal conditions are moderate.

(2) Utility Model Registration Scope of Claims In the oxygen sensor according to claim 1, the thick film element is provided with a thick film sensitive part at one end of the rod-shaped base made of a heat-resistant material, and has a thick film extending from the sensitive part in the longitudinal direction. An oxygen sensor having extended leads and an external lead attachment hole formed at the other end of the base.

(3) Utility Model Registration The oxygen sensor according to claim 1 or 2 is composed of a pair of ceramic supports having a flange at one end and a pair of metal housings 7'; The metal housing is integrally crimped and fixed at the flange part, and the end of the metal housing surrounding the sensitive part of the thick film element is opened and a ventilation hole is bored in the side surface. Oxygen sensor.

(4) Scope of Utility Model Registration Claims Paragraphs 1 to 3
In any one of the oxygen sensors, the sealing glass has approximately the same coefficient of thermal expansion as the ceramic support.

(5) Scope of Utility Model Registration In the oxygen sensor according to any one of claims 1 to 4, the metal housing includes:
An oxygen sensor with a mounting screw provided on the outer periphery of a thick film element close to the part surrounding the sensing part.

(6) In the oxygen sensor according to any one of claims 1 to 5, the ceramic support for glass-sealing the thick film element is a part of the through hole through which the thick film element is inserted. An oxygen sensor that has a cutout step for filling the sealing glass.
