Oxygen sensor

Abstract

The invention relates to an oxygen sensor, which comprises a sensor body; a shell is arranged outside the sensor body; a contact bushing is arranged at the front end of the sensor body; the contact bushing is connected to a cable through a contact spring; insulating ceramic is arranged at the joint of the cable and the contact spring; a protective pipe is connected to the tail end of the shell; a plurality of air inlet and outlet tanks are arranged on the protective pipe; an installation thread is arranged on the shell; a gasket is arranged at the front end of the installation thread; a wire jacket is connected to the front end of the shell; an air inlet is arranged on the wire jacket; the insulating ceramic is arranged in the wire jacket; and the cable is connected to a heater matched with the sensor body. The oxygen sensor disclosed by the invention has the advantages of being simple in structure, easy for maintenance, convenient to use, accurate for measurement and the like; the heater is arranged in the oxygen sensor, therefore, the oxygen sensor can be in the working condition rapidly; the quality is increased; simultaneously, energy can be saved through the reasonable adjusting manner.

Description

technical field [0001] The invention relates to an oxygen sensor. Background technique [0002] At present, with the continuous improvement of people's living standards, automobiles have become a popular means of transportation. Among them, the oxygen sensor is an important part of the motor vehicle engine management system, which is installed in the exhaust system of the motor vehicle to sense the oxygen concentration. , to achieve closed-loop control.
