US 5,688,390 A · Oxygen concentration sensor

Abstract

A laminated type oxygen concentration sensor includes a laminated type oxygen concentration sensor element having a plate shape with a flange on a side surface thereof, and a housing in a tubular shape having an inclination seat inclined in a central axial direction thereof. The housing supports the laminated type oxygen concentration sensor element by contacting the inclination seat with the flange of the laminated type oxygen concentration sensor element at an outer circumference of the inclination seat. Since the sensor element is supported by contacting the flange with the inclination seat of the housing at the outer circumference of the inclination seat, the pressure per unit area imposed on the sensor element is minimized and cracking of the sensor element is prevented.
