The surface of the mounting base plate 1 is provided with a positioning base 2, which is used to precisely fix the voltage detector assembly 16, ensuring its stable position during testing and facilitating subsequent wiring harness connection and testing. The side of the positioning base 2 is provided with a first fixing base 3, which works in conjunction with a rib clip 4 to provide additional support and fixation, ensuring that the rib clip 4 can firmly clamp the voltage detector assembly 16, preventing it from moving or shaking during testing. The surface of the first fixing base 3 is provided with a rib clip 4, which is used to firmly fix the voltage detector assembly 16 onto the positioning base 2, ensuring the accuracy and stability of the connection. The positioning base 2 has a voltage detector assembly 16 inside. The shape and position of the rib clip 4 are adapted to the voltage detector assembly 16. The surface of the mounting base 1 is provided with a guide rail cylinder 7. The guide rail cylinder 7 is a driving component. Through its linear movement, it pushes the second fixed base 5 and the wire harness plug on it to move towards the voltage detector assembly 16 to achieve automatic connection. The end of the guide rail cylinder 7 is provided with the second fixed base 5. The guide rail cylinder 7 and the second fixed base 5 are arranged in a linear array of three sets. The position of the second fixed base 5 corresponds to the positioning base 2. The second fixed base 5 is used to fix and support the wire harness plug to be connected, ensuring its stability and accuracy during movement. The top of the second fixed base 5 is provided with a top cover 6. The top cover 6 is used to fix the wire harness plug on the second fixed base 5 to prevent it from falling off or moving during the test, ensuring the stability of the connection.

[0026] A magnetic switch sensor 10 is provided on the surface of the guide rail cylinder 7. The magnetic switch sensor 10 is used to detect the position of the guide rail cylinder 7. When the second fixed base 5 reaches the predetermined position, the sensor is triggered, thereby controlling the indicator light 12 to illuminate and indicating the connection status to the user. A hydraulic damper 13 is provided on the surface of the guide rail cylinder 7. The positive and negative hydraulic dampers 13 can limit and buffer the forward and reverse strokes to protect the equipment from damage. A speed regulating valve 14 is provided on the surface of the guide rail cylinder 7. The speed regulating valve 14 can be used to regulate the speed and pressure of the guide rail cylinder 7, improving the flexibility and accuracy of the test. An outer cover 11 is provided on the surface of the mounting base plate 1. The outer cover 11 serves as the protective shell of the entire test wiring fixture, preventing dust, debris, etc. from entering the interior, while also providing an aesthetic appearance and a certain degree of safety protection. After the outer cover 11 is installed, the sealing plate is connected to the external air passage. A reversing valve is provided inside the outer cover 11. 8 and connector 9, the reversing valve 8 is used to control the movement direction of the guide rail cylinder 7, realize the automatic connection and disconnection of the wire harness plug and the voltage detector assembly 16. The end of the reversing valve 8 is connected through to the side of the outer cover 11. The surface of the connector 9 is provided with a connecting air pipe 17. The reversing valve 8 is connected to the guide rail cylinder 7 through the connector 9 and the connecting air pipe 17. The connector 9 is a four-way connector, which cooperates with the connecting air pipe 17 to realize the connection between the guide rail cylinder 7 and the reversing valve 8, so that the reversing valve 8 can control the movement of the guide rail cylinder 7. The surface of the outer cover 11 is provided with an indicator light 12. The magnetic switch sensor 10 is electrically connected to the indicator light 12. When the magnetic switch sensor 10 detects that the guide rail cylinder 7 has reached the predetermined position, the indicator light 12 lights up, indicating to the user that the wire harness plug has been successfully connected. The bottom of the mounting base plate 1 is provided with feet 15. The feet 15 are used to fix the entire test plug fixture on the ground or workbench to ensure its stability and safety.

[0027] After inserting the wire harness plug into the second fixed base 5, cover it with the top cover 6 to secure it. Place the voltage inspector assembly 16 into the positioning base 2 and use the clamp 4 to press and fix it. The reversing valve 8 controls the guide rail cylinder 7 through the connecting air pipe 17. At the same time, the hydraulic damper 13 limits and buffers the stroke to protect the equipment. The speed control valve 14 improves the flexibility and accuracy of the test. When plugging in the wire, turn the reversing valve 8 to move the guide rail cylinder 7 forward, pushing the second fixed base 5 to move so that the wire harness plug is accurately connected to the voltage inspector assembly 16, thereby quickly completing the connection between the voltage inspector assembly 16 and the test system. At the same time, the indicator light 12 on the outer cover 11 illuminates after the magnetic switch sensor 10 detects that the position is in place to indicate whether the wire harness is plugged in properly. After plugging in the wire, the test begins. After the test is completed, turn the reversing valve 8 to move the guide rail cylinder 7 backward, completing the disconnection step between the voltage inspector assembly 16 and the test system. Open the clamp 4 to take out the product and complete the test. Specific Implementation Example 2:

[0029] A voltage inspector test wiring fixture for a fuel cell, based on the basic structure in Specific Embodiment 1, further discloses the following: the positioning base 2 can be shared in the calibration voltage station and the voltage detection station, so the whole fixture can achieve the commonality of the two stations and has high versatility. In addition, the control handle of the rib clamp 4 can be set to electric control, which enhances the smoothness of operation and makes the whole testing process more efficient and convenient.

[0030] In summary:

[0031] 1. The system employs a guide rail cylinder 7, a reversing valve 8, a second fixed base 5, a positioning base 2, a magnetic switch sensor 10, and an indicator light 12. This allows the wire harness plug to be inserted into the second fixed base 5, secured by the top cover 6, and the voltage detector assembly 16 placed inside the positioning base 2. The ribs 4 are then used to clamp and secure it. The reversing valve 8 moves the guide rail cylinder 7 forward, pushing the second fixed base 5 to move, ensuring the wire harness plug is precisely connected to the voltage detector assembly 16. This quickly completes the connection between the voltage detector assembly 16 and the testing system. Simultaneously, the magnetic switch sensor 10 illuminates the indicator light 12 on the outer casing 11 after detecting the correct position, indicating whether the wire harness is properly inserted. This design is simple to operate, even for non-professionals, and makes the wiring process faster and easier, greatly improving testing efficiency. Furthermore, the second fixed base 5 and top cover 6 secure the wires, and the reasonable plug connection ensures connection stability, reducing testing errors caused by poor connections and guaranteeing the accuracy and reliability of the test.
