[0024] Please refer to the attached Figure 7 The embodiment of the present invention provides a method for testing the life of a charging gun plug and socket, the method comprising the following steps: Fix the charging gun plug and socket to the charging gun plug fixture and charging gun socket fixture 506 of the fixture module respectively; Set the test parameters on the touch screen, including the number of plug-in and plug-out cycles, plug-in and plug-out speed, contact time, and environmental simulation conditions; Start the mechanical motion module to perform plugging and unplugging actions, and use the data acquisition module to record the insertion force and extraction force data in real time; According to the test requirements, the samples were immersed in acid rain solution, mixed salt solution or pure acid solution for 5 minutes; After the soaking is completed, continue to perform the plugging and unplugging actions and record the changes in the insertion force and extraction force.

[0025] The test parameters were insertion and extraction speed of 0.8 m / s, contact time of 2 to 4 seconds, and number of insertion and extraction cycles of 10,000 times.

[0026] The concentration of the mixed salt solution is 5%, and the concentration of the pure acid solution is 10%.

[0027] In each plugging and unplugging cycle, the peak values ​​of the insertion force and the extraction force are measured in real time by the force sensor, and a curve report of the insertion force and extraction force changes is generated after the test is completed.

[0028] During the plugging and unplugging process, the force value, displacement and cycle number data recorded by the data acquisition module are displayed in real time through the touch screen and stored as a test record file.

[0029] After completing the plug-in and unplug action and environmental simulation test, the sample is surface treated by an air-drying device. The air-drying mode is normal temperature or heating mode, and the air-drying time is set to 1 to 5 minutes according to the type of solution.

[0030] Specifically, first, fix the charging gun plug and socket on the charging gun plug fixture and charging gun socket fixture 506 of the fixture module respectively to ensure that the plug and socket are stable and do not shift during the test, and then set the test parameters on the touch screen. The test parameters include the number of plugging and unplugging cycles, plugging and unplugging speed, contact time and environmental simulation conditions, where the number of plugging and unplugging cycles is set to 10,000 times, the plugging and unplugging speed is set to 0.8 m / s, and the contact time is set to 2 to 4 seconds. All parameters can be adjusted according to specific test requirements. After the setting is completed, start the mechanical motion module, which drives the charging gun plug fixture to perform plugging and unplugging actions, and at the same time, the data of insertion force and extraction force are recorded in real time through the data acquisition module.

[0031] According to the test requirements, after the plugging and unplugging action is completed, the sample is immersed in an acid rain solution, a mixed salt solution or a pure acid solution for environmental simulation testing. The composition of the acid rain solution conforms to the standard ratio. The volume ratio of sulfuric acid to nitric acid is 3:1, and the total concentration is controlled between 0.01 mol / L and 0.05 mol / L. The pH value of the solution ranges from 3.5 to 5.0. The concentration of the mixed salt solution is 5%, and the concentration of the pure acid solution is 10%. The immersion time is set to 5 minutes to ensure that the surface of the sample can fully contact the solution to simulate the corrosive conditions in the actual use environment. After the immersion is completed, the plugging and unplugging action is continued. During this process, the changes in the insertion force and the extraction force are recorded in real time. The peak force value in each plugging and unplugging cycle is accurately measured through the data acquisition module, and a change curve report of the insertion force and the extraction force is generated. The report can be directly viewed or exported on the touch screen for subsequent data analysis.

[0032] During the entire plugging and unplugging process, the data acquisition module will also synchronously record data such as insertion force, extraction force, displacement, and number of cycles. These data are displayed in real time on the touch screen, and the operator can monitor the progress of the test in real time. At the same time, these data are automatically stored as test record files for subsequent viewing and analysis. The storage file format supports multiple data output forms, which is convenient for comprehensive evaluation. Finally, after completing all plugging and unplugging actions and environmental simulation tests, the sample is surface treated and quickly air-dried by an air-drying device. The air-drying device supports two modes: normal temperature and heating. The specific air-drying time is set to 1 to 5 minutes according to the type of solution to ensure that there is no residual solution on the surface of the sample and does not affect the subsequent analysis and test results. This method is easy to operate, with adjustable parameters, and can accurately evaluate the life performance of the charging gun plug and socket in the actual use environment.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
