Description

Technical Field

[0001] The utility model relates to the technical field of automobile oxygen sensors with stable installation, in particular to an automobile oxygen sensor with stable installation. Background Art

[0002] The automotive oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system. It is a key component for controlling automobile exhaust emissions, reducing automobile pollution to the environment, and improving the fuel combustion quality of automobile engines. Oxygen sensors are all installed on the engine exhaust pipe.

[0003] For example, the authorization announcement number is "CN220040315U", which is a stable installation automotive oxygen sensor. The sensor body is first fixed on the exhaust pipe of the vehicle by rotating it, and then an elastic part is put on. The elastic pull plate is frictionally sleeved on the sensor body, and then the elastic hook is bent to insert it into the buckle groove. Then the hexagonal nut is rotated to cooperate with the gasket to fix the sensor body on the exhaust pipe to complete the fixation. The elastic pull plate and the elastic hook are used to limit the rotation of the hexagonal nut, and then the elastic part is used to absorb the vibration from the hexagonal nut, so that the sensor body is fixed on the exhaust pipe more stably, solving the problem that the existing sensor body is easy to loosen or fall on a vehicle with violent movement. However, when the automotive oxygen sensor is used, after being installed on the electronic fuel injection engine, the top connecting wire will bend downward, which will cause the connection between the connecting wire and the electronic fuel injection engine to be directly bent. After long-term use, the skin of the bending part of the connecting wire will break, causing the wire core to leak out, increasing the danger of using the electronic fuel injection engine and shortening the service life of the electronic fuel injection engine.
