[0002] Connectors are widely used in electronics, electrical, mechanical and other fields. Their main function is to achieve connection and signal transmission between different devices, components or systems. Usually, before using the connector, the performance of the connector needs to be tested to ensure the reliability of the connector performance and quality.

[0003] The current connector testing equipment mainly uses a single conduction mode for operation testing. Often, a set of test systems is required for a connector of a certain model. After the test is completed, the equipment needs to be replaced and clamped repeatedly, and the detection method is relatively cumbersome. In addition, the existing test systems and connectors are mainly from foreign manufacturers. For some customized domestic connectors, the existing test systems often have differences in interface adaptability, operating conditions, etc., and cannot meet the performance test requirements of customized connectors. Summary of the invention

[0036] The connector performance detection system in this application is mainly aimed at domestic customized connectors. Since different manufacturers adopt different design methods when meeting design requirements, the delivered connectors have different model parameters, and the imported detection system is often aimed at a single product, which cannot meet the testing requirements of customized connectors. Based on this, the present application corresponds to the setting of a connector performance detection system, which sets multiple plug-in areas 202 in a single test system, and sets multiple different plug-in ports in the plug-in area 202, so that a test system can test multiple different connectors at the same time, greatly improving the testing efficiency of customized connectors. At the same time, as mentioned above, due to the differences in the operating parameters of different connectors, the present application also corresponds to the setting of a power conversion module to adjust the output voltage to adapt to the working conditions of connectors of different models, and finally completes the parameter reading of the connector 3 to be tested through the test component to confirm whether the connector meets the requirements. The connector performance detection system in this application can simultaneously realize the detection of multiple connectors 3 to be tested, avoiding the problem that the conventional test system needs to frequently plug and unplug different connectors, and at the same time, different plug-in ports can adapt to the rapid docking test of non-standard connectors to efficiently complete the performance test of the connector.
