Cylinder temperature sensor with protection structure

Abstract

The invention discloses a cylinder temperature sensor with a protection structure. The sensor comprises a shell, a connecting rod, a hollow pipe and a protective block, a preformed groove is formed inthe shell. An organic silicon high-temperature-resistant layer is arranged on the side wall of the bottom end in the preformed groove; a thermistor is mounted at the bottom end of the interior of thepreformed groove; a first wiring pin is mounted on one side of the top end of the thermistor; a second wiring pin is mounted on the other side of the top end of the thermistor; a first inserting partis arranged on one side of the upper portion of the thermistor, the bottom end of the first inserting part is connected with the top end of a first wiring pin, a second inserting part is arranged onthe other side of the upper portion of the thermistor, the bottom end of the second inserting part is connected with the top end of a second wiring pin, and a hollow pipe is installed in the middle ofthe bottom end of the shell. By uniformly arranging the organic silicon high-temperature-resistant layer on the side wall of the bottom end in the preformed groove, the high-temperature-resistant capacity is improved. Meanwhile, temperature leakage is prevented, and the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a cylinder temperature sensor with a protective structure. Background technique [0002] The cylinder temperature sensor is an electronic component used to detect the temperature of the engine block. Detecting the temperature of the engine is of great significance to the calculation of air volume, idle speed and temperature protection. In order to meet the needs of the market, various new cylinder temperature sensors have emerged , but there are many problems or defects in the existing cylinder temperature sensor. [0003] First, the traditional cylinder temperature sensor has no protective structure, and the structural strength of the sensor body is not high. [0004] Second, the traditional cylinder temperature sensor does not have an anti-seize structure. During installation, if the thread is stuck at a right angle to the interface of the engine cylinder, it will be difficult...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a cylinder temperature sensor with a protective structure, to solve the problem that there is no protective structure in the above-mentioned background technology, the structural strength of the sensor body is not high, and there is no anti-seize structure. The right angle of the body interface is stuck, it is difficult to disassemble and the accuracy of the test results is not high
