The invention discloses an anti-explosion temperature sensor for an air compressor. A wiring box is connected with a radiating adapter through a thread plug. The radiating adapter is connected with a casing pipe through a screw nut. A platinum resistor element is arranged in the casing pipe. The end, adjacent to the radiating adapter, of the platinum resistor element is connected with the radiating adapter through a spring sleeve. A wiring board is fixed in a wiring box body. The side, away from the thread plug, of the wiring board is connected with a wiring pillar. An electric interface is formed in one side of the wiring box. The front end, adjacent to the radiating adapter, of the casing pipe is provided with threads. The casing pipe is in threaded connection with the screw nut as the threads of the front end of the casing pipe are matched with the threads of the inner wall of the screw nut. The end, adjacent to the radiating adapter, of the screw nut is provided with a stair-shaped step. The front end of the casing pipe is tightly abutted against the end, adjacent to the casing pipe, of the radiating adapter. The front end of the casing pipe, the inner side wall of the screw nut and the end, adjacent to the casing pipe, of the radiating adapter define a sealed space. A stop block is arranged in the sealed space and fixedly connected with the front end of the casing pipe.
Description
technical field [0001] The invention relates to the technical field of temperature sensors, in particular to an explosion-proof temperature sensor for an air compressor. Background technique [0002] Temperature is a basic physical quantity. All processes in nature are closely related to temperature. As a sensor for measuring temperature, temperature sensors can convert temperature information into usable output signals. Temperature sensors have a wide range of applications and a huge market share. [0003] Due to the particularity of the use environment, the temperature sensor for air compressor needs to have good explosion-proof performance. In the prior art, in order to make the explosion-proof performance of the air compressor temperature sensor comply with the relevant requirements of national standards, the design is too complicated and difficult to assemble. Contents of the invention [0004] In order to solve the technical problems existing in the background techn...
