Technical Field

The utility model relates to the technical field of temperature monitoring, in particular to a temperature sensing assembly with an adjustable angle and a charging device.

Background

A temperature sensor refers to a sensor that senses temperature and converts it into a usable output signal. The contact type temperature measuring device is simple and reliable, and has high measuring precision. However, the temperature measurement device must be contacted with the transition terminal to measure the temperature, and the installed transition terminal needs to maintain a certain pressure with the temperature measurement device to more accurately measure the temperature of the transition terminal. However, the existing temperature measuring structure can only enable the transition terminal and the temperature sensor to be in contact, when the installation environment vibrates or moves, the transition terminal can displace, so that the transition terminal and the temperature sensor deviate and cannot be in close contact, and the temperature measured by the temperature sensor is inaccurate. In the field of new energy automobiles, if a control system of a charging device executes incorrect temperature control measures according to inaccurate temperature information, the charging efficiency is affected if the temperature is light, and the charging device is burnt out due to overhigh temperature. There is currently a lack of a way to provide sustained pressure to more tightly conform the transition terminal to the temperature sensor. Therefore, there is a need in the art for a temperature measurement structure that can accurately measure the temperature of the transition terminal by closely contacting the temperature sensor with the transition terminal.
