Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, and particularly relates to an engine exhaust temperature sensor. Background Art

[0002] The exhaust temperature sensor detects the temperature of the intake air, providing a basis for the vehicle's ECU to calculate the air density. The exhaust temperature is the temperature that remains on the cross-section of the engine turbine outlet after the combustion gas is discharged from the combustion chamber and passes through the high-speed rotating turbine.

[0003] Chinese Patent with Publication No. CN218381348U discloses an engine exhaust temperature sensor, which includes a connecting member, a temperature sensing member and a separating member. The connecting member includes a connecting plate, and one end of the connecting plate is connected with a junction box.

[0004] Although in the above patent, during use, the studs on the periphery of the rod head are passed through the through holes and fixed on the connecting plate with nuts, and the rod head can be removed by removing the nuts, so that the circuit inside the rod head can be repaired. However, since the studs are arranged in four on the connecting block, when the circuit inside the rod head needs to be repaired, the repairman needs to remove the nuts one by one to separate the studs from the connecting plate, which not only makes the removal and installation of the rod head more cumbersome, but also the setting of more parts will increase the manufacturing cost. Therefore, a new type of engine exhaust temperature sensor is urgently needed to solve these problems. Content of the Utility Model
