[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-7 ;

[0027] A charging gun wiring harness testing device includes a base 1, a power supply module 2 mounted on the base, at least one test module 3 located on one side of the power supply module 2, a bracket 4 behind the test module 3, a keyboard holder 5 and a display 6 placed on the bracket 4, a keyboard 51 placed on the keyboard holder 5, and the display 6, keyboard 51 and test module 3 electrically connected. The power supply module 2 simultaneously provides power to the keyboard 51, display 6 and test module 3. When detailed data needs to be input or test conditions need to be set, the user can easily remove the keyboard 51 from the keyboard holder 5 for operation and control via the display. The device 6 can view the working status and test results of the test module 3 in real time, so as to intuitively monitor the changes of various indicators during the test and make corresponding adjustments in time. After the operation is completed, the keyboard 51 can be put back on the keyboard holder 5, which not only saves space, but also reduces the risk of equipment damage. The test module 3 includes a test socket 31, which is provided with a slot 32 for inserting the charging gun body 7. The slot 32 is provided with several contact pins 33, which are used to connect with the corresponding contacts on the plug of the charging gun body 7, so as to realize the transmission of electrical energy and signal transmission, so as to test the charging gun body 7.

[0028] Specifically, the standard test parameters are first set and saved to the data storage module. The data storage module then transmits the set data to the comparison module for subsequent comparison. Subsequently, the charging process is initiated by the microprocessor, and data transmission is achieved during this process. Throughout the test, the timing module triggers data acquisition at predetermined time intervals (e.g., every minute), collecting the current test data and sending it to the comparison module for immediate comparison and analysis with the pre-set standard values. Finally, a test report is output based on the comparison results to determine whether the charging gun body 7 meets safety and performance requirements. For example, if the maximum allowable charging current of the charging gun body 7 is 32A, during the test, the microprocessor controls the start of charging, and the timing module triggers data acquisition every minute to record the current charging current value. If, after 10 minutes of testing, the data storage module records a charging current value of 31.8A, the comparison module compares this actual measured value of 31.8A with the preset maximum allowable charging current of 32A. Since 31.8A is less than 32A, the comparison module determines that the measurement result is qualified and continues... The system monitors current changes during the remaining test period. If all measurements remain within the safe range throughout the entire test cycle, the test report will ultimately show that the current control function of the charging gun body 7 is normal and meets the usage requirements. The display 6 will show OK and NG prompts. It can also print barcodes and QR codes, scan barcodes and QR codes, and track test results. The test results are arranged in chronological order. If the measured value at a certain point in time exceeds the preset safe range during the test, for example, if the actual charging current recorded by the data storage module reaches 33A at the 15th minute, exceeding the maximum allowable 32A, the comparison module will identify this abnormal situation and immediately transmit the relevant information to the microprocessor. After receiving the signal, the microprocessor can react quickly and command the test module 3 to immediately stop charging to avoid safety hazards caused by current overload. At the same time, the data storage module will also record the exact time of the abnormality and the value exceeded, and generate a comprehensive test report containing all test data and a description of the abnormal situation for reference in subsequent product optimization or maintenance.

[0029] In this embodiment, there are two test modules 3. Since the testing of the charging gun body 7 requires a certain amount of time, the two charging gun bodies 7 can be tested simultaneously, thereby improving the testing efficiency.

[0030] In another embodiment, in order to facilitate the fixing of the charging gun body 7 during testing, the test base 31 is provided with a fixing bracket 34 for fixing the charging gun body 7 on the outer periphery of the slot 32. The fixing bracket 34 is provided with a positioning groove 35, and the charging gun body 7 is provided with a positioning block 71. When inserting the charging gun body 7, the positioning block 71 is aligned with the positioning groove 35 before insertion. Through the positioning of the positioning block 71 and the positioning groove 35, it is avoided that the socket of the charging gun body 7 is difficult to align with the contact pin 33 when it is inserted, thereby improving the testing efficiency.

[0031] In another embodiment, the positioning groove 35 is provided with a U-shaped groove 72, and the fixing frame 34 is provided with an automatic fastening assembly that can be inserted into the U-shaped groove 72. Specifically, the automatic fastening assembly includes a protrusion 341, the protrusion 341 is provided with an insertion hole 342 corresponding to the U-shaped groove 72, and vertical rods 343 are symmetrically provided on both sides of the slot 32. A U-shaped block 344 is slidably connected to the two vertical rods 343. The U-shaped block 344 can be inserted into the U-shaped groove 72. The vertical rod 343 is provided with a limiting part 345, and a spring 346 is sleeved on the vertical rod 343. The spring 346 is located between the limiting part 345 and the U-shaped groove 72, with one end connected to the limiting part 345 and the other end connected to the U-shaped block 344, so that when the charging gun body 7 is inserted, the positioning block 71 will move along the preset slot 32. As the charging gun body 7 is inserted deeper... As the charging gun body 7 is pushed forward, the positioning block 71 eventually reaches the position of the U-shaped block 344. During this process, the positioning block 71 pushes the U-shaped block 344 upward, thereby compressing the spring 346. As the charging gun body 7 is further pushed forward, the slot 32 and the socket 342 on the protrusion 341 gradually align. During this period, since the spring 346 is always in a compressed state, it will apply a continuous downward force to the U-shaped block 344. When the slot 32 and the socket 342 are fully aligned, the U-shaped block 344 will move downward rapidly under the action of the spring 346 until it is fully embedded in the U-shaped groove 72 of the positioning groove 35, thereby locking the charging gun body 7. After the test is completed, the charging gun body 7 can be directly pulled out. When pulled out, the U-shaped block 344 will automatically move upward along the U-shaped groove 72 without the need to manually pick up the U-shaped block 344.

[0032] In another embodiment, in order to ensure that the power supply module 2 can maintain good heat dissipation during long-term operation, a vertical plate 8 is provided at the rear of the power supply module 2, and a cooling fan 81 is installed on the vertical plate 8. The vertical plate 8 is provided with a fan through hole corresponding to the cooling fan 81, so that the cooling fan 81 can directly blow air onto the power supply module 2, effectively removing the heat generated by the module during operation.
