Problems solved by technology

However, there is no special tool for this kind of test. Generally, the test is carried out by manual stretching. As long as it does not fall off after stretching, it is judged that the connection is reliable.
However, such stretching is a cumbersome job for the operator, and the hand will hurt after repeated stretching, which will affect the normal work. Therefore, it is very necessary to design a tool that can test the firmness of the connection between the thermocouple head and the wire. of

The invention has reasonable design, convenient use and high testing accuracy.

Description

technical field [0001] The invention relates to a thermocouple tensile testing device. Background technique [0002] Thermocouple (thermocouple) is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). Such as figure 1 Shown is a common thermocouple, including a thermocouple head 11 and a wire 12 . [0003] Before using the thermocouple, a pull test is performed on the connection between the thermocouple head and the wire to determine whether the two are firmly connected. However, there is no special tool for this kind of test, and the test is generally carried out by manual stretching. As long as it does not fall off after stretching, it is judged that the connection is reliable. However, such stretching is a cu...
