Claims (1)
てなる管体の内部に、酸素イオン伝導性固体電解
質の積層体からなる長尺板状検出素子を絶縁保護
層で保持して配設し、その先端を絶縁保護層から
露出して検出端とすると共に、金属製外筒の内部
には絶縁保護層の一部となるガラス等からなる封
止層を充填して溶融固化し、検出素子後端の導線
接続端を保護した構成を備える酸素センサにおい
て、 封止層と金属製外筒との間に、０．０５mm〜０
．２mmの厚さの、金属製倣い材料からなる熱緩衝
層を設けたことを特徴とする酸素センサ。[Scope of Claim for Utility Model Registration] A long plate-shaped detection element made of a laminate of an oxygen ion-conducting solid electrolyte is placed inside a tube formed by connecting a metal outer cylinder to the rear end of a tubular base metal fitting. It is held by an insulating protective layer and its tip is exposed from the insulating protective layer to serve as a detection end, and inside the metal outer cylinder is a sealing layer made of glass etc. which becomes a part of the insulating protective layer. In an oxygen sensor, the oxygen sensor has a structure in which the conductor connection end at the rear end of the detection element is protected by filling and melting and solidifying the oxygen.
．． An oxygen sensor characterized by providing a thermal buffer layer made of a metal copying material with a thickness of 2 mm.
