Connecting mechanism of thermocouple wire and thermocouple plug

Abstract

The utility model discloses a connecting mechanism of a thermocouple wire and a thermocouple plug, which comprises a buffer adjusting mechanism and a thermocouple wire, the upper end of the thermocouple wire is fixedly connected with a bendable copper sheet, one end of the bendable copper sheet is fixedly connected with a conductive insertion sheet, and the buffer adjusting mechanism comprises a main body supporting top block. And the inner top wall of the main body supporting top block is fixedly connected with a limiting shaft rod. When thermocouple temperature measurement is carried out, a thermocouple wire is pulled, the thermocouple wire drives a slidable adjusting block to slide downwards on the surface of a limiting shaft rod while being pulled outwards, and a connecting supporting block drives a buffer spring to be lengthened, so that when a bendable copper sheet and a conductive insertion sheet are installed together, the bendable copper sheet and the conductive insertion sheet are fixed together, and the temperature of the thermocouple is measured. Therefore, when the thermocouple wire is pulled out of the thermocouple plug and is used for maintenance, the thermocouple wire is prevented from being pulled apart due to too large pulling force, and normal output of electric power is prevented from being influenced.
