Thermistor

Abstract

The invention belongs to the technical field of electrical apparatus elements, and particularly relates to a thermistor, which comprises a mounting base, a rotating ring and a thermistor body. The rotating ring is rotatably connected to the central position of a housing in the housing; a strip-shaped groove is formed in the upper surface of the rotating ring; the thermistor body is arranged in thestrip-shaped groove; mounting grooves are formed in the positions, corresponding to the second through holes, of the rotating ring; conductive blocks are fixedly connected in the mounting grooves; annular grooves are formed in the positions, corresponding to the height of the conductive blocks, of the inner arc surface of the mounting base; conductive rods are fixedly connected to the surfaces ofthe conductive blocks; the ends, away from the conductive blocks, of the conductive rods penetrate through the rotating rings and extend into the annular grooves; and conductive connectors are arranged at the positions of the annular grooves in the four side faces of the mounting base. According to the invention, rapid connection of a plurality of thermistors is effectively realized, connection and disconnection can be manually controlled without welding, and the installation compactness of the thermistors is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electrical components, in particular to a thermistor. Background technique [0002] Thermistors are a type of sensitive components. According to different temperature coefficients, they are divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors. The typical characteristic of thermistors is that they are sensitive to temperature and behave at different temperatures The resistance value of the positive temperature coefficient thermistor is higher when the temperature is higher, and the resistance value of the negative temperature coefficient thermistor is lower when the temperature is higher. They both belong to semiconductor devices. [0003] In the prior art, it is often encountered that several thermistors are used very close to each other. Since the thermistors are all of a single structure, the wiring when using multiple thermistors is relatively cumb...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the situation in which several thermistors are used very close to each other in the prior art, since the thermistors are all of a single structure, the wiring when using multiple thermistors is relatively cumbersome , and when the voltage is too high, the resistance of a single thermistor is too small, it is difficult to meet the problems of circuit protection, etc., a thermistor proposed by the present invention
