[0082] More specifically, the second positioning mechanism 5 is provided with a displacement sensor 11, which can detect the position information of the switch 200 to be tested and the test connector 100 during the plugging and unplugging process. The displacement sensor 11 is communicatively connected to the control module 10, and the control module 10 can adjust the relative distance and relative angle between the first positioning mechanism 4 and the first positioning mechanism 4 according to the position information.

[0083] More specifically, the detection module 6 specifically integrates a tension and pressure sensor, a voltage sensor, a current sensor and a resistance sensor.

[0084] The tension and pressure sensor is used to measure the tension and pressure applied to the switch 200 under test during the plugging and unplugging process. The magnitude and direction of these forces are crucial to evaluating the durability of the switch 200 under test, and can reveal whether the switch 200 under test can maintain stable performance under long-term use. At the same time, these data also reflect the smoothness of the plugging and unplugging operation, as well as the mechanical stress that may be generated during the plugging and unplugging process, providing a key basis for optimizing the design.

[0085] The voltage sensor can monitor the voltage change between the test connector 100 and the switch to be tested 200 in real time. The voltage sensor can detect voltage fluctuations or abnormal conditions in a timely manner, providing an important early warning mechanism for preventing equipment damage and accidents. By continuously monitoring voltage changes, the safety of the test process and the reliability of the data can be ensured.

[0086] The current sensor is responsible for measuring the magnitude and direction of the current passing through the test connector 100. The magnitude and change of the current directly reflect the operating status and load conditions of the electrical equipment. The data provided by the current sensor is of great significance for evaluating the performance of the switch 200 under different load conditions, and also provides strong support for subsequent equipment optimization and fault diagnosis.

[0087] The resistance sensor focuses on measuring the resistance value of the test connector 100 and its connecting parts. The change in resistance value is an important indicator for evaluating the contact quality and electrical connection status of the switch 200 to be tested. By monitoring the change in resistance value, it is possible to timely find out whether the contact of the switch 200 to be tested is good, whether there is oxidation or corrosion, and other problems, and then comprehensively evaluate the electrical connection quality of the switch 200 to be tested.

[0088] That is to say, the detection module 6 can provide real-time and accurate monitoring capabilities, which helps to ensure that the switch 200 to be tested maintains stable performance in a complex and changing electrical environment. The tension and pressure sensors, voltage sensors, current sensors and resistance sensors work simultaneously to ensure the comprehensiveness and accuracy of the test.

[0089] Figure 6 The schematic diagram of the structure of the test connector provided by the embodiment of the present invention is shown. Figure 6 The test connector 100 includes a power line 110 and a data line 120. The distance between the end of the power line 110 and the socket of the test connector 100 is smaller than the distance between the end of the data line 120 and the socket of the test connector 100. When the test connector 100 is plugged into the switch 200 to be tested, the connection between the power line 110 and the switch 200 to be tested precedes the connection between the data line 120 and the switch 200 to be tested.

[0090] Through the above arrangement, during the plugging and unplugging process of the test connector 100 and the switch to be tested 200, the power line 110 can first establish a connection with the switch to be tested 200 before the data line 120. Such a design ensures that the system can quickly reach a stable state when powered on, and is ready for the upcoming data transmission. After the power line 110 is stably connected to the switch to be tested 200, the data line 120 will contact the switch to be tested 200 and start the data measurement activity. Such a sequence ensures that the device is in a stable powered-on state before transmitting data, thereby improving the accuracy and reliability of the test. When the test is completed and the switch to be tested 200 needs to be unplugged, the operation sequence is reversed. The data line 120 will first be disconnected from the switch to be tested 200 to stop data transmission, and then the power line 110 will be separated from the switch to be tested 200, ensuring that the hardware device has stopped data transmission before the power is disconnected. Such an operation sequence avoids hardware damage that may be caused by data transmission at the moment of power failure.

Figure 8 A front view showing a partial structure of a hot-swap test tool provided by an embodiment of the present invention Figure 3 . Reference Figure 7 and Figure 8 The hot-swap test tool further includes a protective cover 12. The protective cover 12 is disposed on the machine platform 1, and the guide mechanism 2, the lifting platform 3, the first positioning mechanism 4 and the second positioning mechanism 5 are all disposed in the protective cover 12. The protective cover 12 can effectively isolate the test area from the external environment.

[0092] Preferably, in this embodiment, the protective cover 12 is made of a transparent material, allowing the operator to monitor the test situation in real time.

[0093] Specifically, a door body 13 is movably provided at the opening of the protective cover 12, and the door body 13 can open or cover the opening of the protective cover 12. In this embodiment, the door body 13 can be closed and opened by pushing and pulling.

[0094] Specifically, the protective cover 12 is provided with a heat dissipation fan 14, which is connected to the internal space and the external space of the protective cover 12. The switch 200 to be tested and the test connector 100 may generate a certain amount of heat due to the passage of current. The provision of the heat dissipation fan 14 can effectively accelerate the flow of air inside the protective cover 12, take away the heat in time, reduce the internal temperature, and ensure that the device operates in a suitable working environment.

[0095] More specifically, a temperature sensor 15 is provided in the protective cover 12, and the temperature sensor 15 can detect the temperature of the internal space of the protective cover 12. A humidity sensor 16 is provided in the protective cover 12, and the humidity sensor 16 can detect the humidity of the internal space of the protective cover 12. The temperature sensor 15 and the humidity sensor 16 are both connected to the control module 10 for communication, and can transmit the temperature signal and the humidity signal in the test area to the control module 10, so as to realize the real-time monitoring and precise control of the test environment, and provide a strong guarantee for the accuracy of the test results and the long-term stable operation of the equipment.
