[0002] As the popularity of electric vehicles increases, people have higher and higher requirements for the quality of electric vehicles. Among them, batteries are one of the important components of electric vehicles. Each battery needs to be measured by OVC (open circuit voltage) testing equipment to ensure its quality.

[0003] For example, Chinese utility model patent CN215575570U discloses a battery OCV test fixture, a base, a positive probe and a negative probe for contacting the battery to be tested, and a plurality of positioning brackets are arranged between the positive probe and the negative probe. The positioning bracket is used to provide support force for the battery to be tested and align the positive and negative electrodes of the battery to be tested with the positive probe and the negative probe, respectively.

[0004] However, it still has the following disadvantages. In module testing, the sizes of module cells are different, so the corresponding OCV test equipment is also different and cannot be compatible.

[0005] Based on this, the utility model designs a quick-change fixture for OCV testing to solve the above problems. Utility Model Content

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. The utility model drives the quick-connect connector to adjust the installation distance by sliding the support plate of the quick-connect connector assembly along the second slide groove. When the position adjustment of the quick-connect connector is completed, the quick-connect connector is plugged and connected to the quick-connect connector. At this time, the locking block and the fixed block are locked by rotating clockwise. When the test is completed, the locking block and the fixed block are separated by rotating counterclockwise. At this time, the test is completed by pulling the quick-connect connector out of the quick-connect connector.
