[0002] With the continuous development of new energy vehicles, the demand for charging new energy vehicles through charging piles is increasing. Therefore, the demand for power inverters in charging piles is also increasing. In charging piles, common power inverters can be divided into two categories: DC power converters and AC power converters. DC power converters mainly convert input constant AC power into output adjustable DC power; AC power converters mainly convert input constant voltage and frequency AC power into AC output with adjustable voltage and frequency.

[0003] The aging test of power converters is mainly a high-intensity test that simulates various harsh conditions of power converters in actual use, and at the same time, according to the requirements of use, reasonably predicts the service life of power converters. At present, batch aging tests of power converters are usually carried out on aging test racks in aging rooms. In order to improve the test efficiency, multiple power converters are tested together during the test. Each power converter needs to be powered by an independent power supply cable. When the number of tested power converters is large, in order to ensure that the connection relationship between the power supply cable and the power converter is clear enough to ensure the accuracy of the test results, the connectors of the power supply cables are usually numbered first, and then the power converters are connected one by one according to the corresponding numbers. In this process, the many power supply cables scattered on the aging test rack are prone to cross-entanglement. It is very cumbersome to comb the cables, and the temperature inside the aging room is high, which will cause physical discomfort to the staff. Utility Model Content
