Temperature sensor

Abstract

The invention relates to the field of sensors, and particularly relates to a temperature sensor which comprises a first connecting rod, wherein a connecting cylinder is arranged at one end of the first connecting rod, a second connecting rod is arranged at one end of the connecting cylinder, a connecting threaded ring is arranged on the outer surface of one side of the connecting cylinder, an internal thread is arranged at the position, which is close to the edge, of the outer surface of the inner side of the connecting cylinder, a wiring harness is arranged in the second connecting rod in a penetrating mode, an insulating shell is arranged at one end of the first connecting rod, a mounting plate is arranged on the outer surface of the front end of the insulating shell, a mounting hole isformed in the outer surface of the mounting plate, a flexible connecting piece is arranged between the mounting plate and the insulating shell, and an elastic protruding block is arranged on the outersurface of the lower end of the mounting plate. According to the temperature sensor, the length of the temperature sensor can be changed, the temperature sensor can be bent and is comprehensive, in the mounting process, the insulating shell and the mounting surface are stable, and a better application prospect is brought.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a temperature sensor. Background technique [0002] A temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of a temperature measuring instrument and has a wide variety. The thermistor is made of semiconductor material, and its resistance value decreases with the increase of temperature. The large resistance value changes, so it is the most sensitive temperature sensor; the existing temperature sensor has certain disadvantages in use. First, the length of the temperature sensor itself cannot be changed, and it cannot be bent, which is not comprehensive enough. During the process, the insulating shell and the mounting surface are usually fixed by glue, which is not stable enough; [0003] Although the length of the wiring harness can be adjusted artificially according to actual needs during insta...

[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of a temperature measuring instrument and has a wide variety. The thermistor is made of semiconductor material, and its resistance value decreases with the increase of temperature. The large resistance value changes, so it is the most sensitive temperature sensor; the existing temperature sensor has certain disadvantages in use. First, the length of the temperature sensor itself cannot be changed, and it cannot be bent, which is not comprehensive enough. During the process, the insulating shell and the mounting surface are usually fixed by glue, which is not stable enough;

[0003] Although the length of the wiring harness can be adjusted artificially according to actual needs during installation, the position of the temperature detection head is fixed during the process of unified use after installation, but in a space that is sometimes closed and sometimes circulated, such as a motor car The compartment needs to be kept in a temperature-controlled state all year round so that the passengers are at a comfortable temperature, but the temperature at a place closer to the air-conditioning outlet is significantly lower than that at a place far from the air-conditioning outlet, causing some people in the same compartment to feel Extremes of cold and hot occur; for this purpose, we propose a temperature sensor
