This paper investigates the structure design problem for the thermocouple junction in spacecraft thermal vacuum tests. Due to the different configurations during the tests, the length and the number of thermocouples are always different, which would lead to certain cost. As a result, a novel thermocouple integrated junction structure is developed and the thermocouple wire can be re-used. The experiment demonstrates that the proposed design method can save the spacecraft thermal vacuum test cost and considerably improve the test efficiency.
