[0023] Example 1: This embodiment of the invention provides a batch testing platform for power distribution terminals, such as... Figures 1-10 As shown, it includes: a test bench body 1, several placement seats 2 are provided on the upper surface of the test bench body 1, placement holes 3 are provided in the placement seats 2, a mounting plate 4 is provided on the rear side of the test bench body 1, the mounting plate 4 is vertically arranged, the lower end of the mounting plate 4 is fixedly connected to the upper surface of the test bench body 1, several module carrier plates 5 are provided on the front side of the mounting plate 4, the module carrier plates 5 are detachably connected to the mounting plate 4 through a connecting mechanism, several test modules 6 are provided on the front side wall of the module carrier plates 5, a horizontal plate 7 is provided on the upper end of the mounting plate 4, a first electric push rod 8 is provided on the horizontal plate 7, the lower end of the first electric push rod 8 passes through the horizontal plate 7 and is provided with a lower pressure plate 9, and several sets of probe assemblies are provided on the lower surface of the lower pressure plate 9; Several placement seats 2 are arranged in a rectangular array on the surface of the test stage body 1, and each of the placement seats 2 corresponds to a number of probe components.

[0024] The working principle and beneficial effects of the above technical solution are as follows: During testing, the operator places the power distribution terminal body 33 to be tested into the placement seat 2 on the upper surface of the test bench body 1. The power distribution terminal body 33 is limited by the placement hole 3. The placement seat 2 is arranged in a rectangular array, which can place multiple power distribution terminal bodies 33 at one time, thereby realizing batch testing. Then, according to the model of the power distribution terminal body 33 to be tested (such as different functional requirements), the corresponding module carrier board 5 is replaced by the connecting mechanism. The corresponding test module 6 is installed on the front side of the replaced module carrier board 5. The test module 6 includes a communication module, a switch module, and an analog module. During the replacement process, it is not necessary to disassemble the test bench body 1 or replace the entire set of tooling, thereby quickly matching the corresponding power distribution terminal body 33. Then, the first electric push rod 8 on the horizontal plate 7 is activated. The first electric push rod 8 is pushed down and drives the lower pressure plate 9 to move downward. The lower pressure plate 9 drives the probe assembly on its lower surface to move downward. The probe assembly aligns with the pins of the power distribution terminal body 33 within the placement base 2, enabling synchronous contact between multiple probe assemblies and the pins of multiple power distribution terminal bodies 33. This eliminates the need for manual insertion and removal of wires for each unit, avoiding damage to terminal pins due to manual wiring errors and reducing testing risks and losses. After the probe assembly contacts the pins of the power distribution terminal body 33, the test module 6 establishes an electrical connection between the probe assembly and the power distribution terminal body 33, and synchronously begins functional testing. The communication module can perform communication protocol verification, the switch quantity module can perform switch quantity response testing, and the analog quantity module can perform analog quantity acquisition accuracy testing. During the test, the first electric push rod 8 maintains a stable downward pressure to ensure reliable contact between the probe assembly and the pins, improving the accuracy of the test results. After the test is completed, the first electric push rod 8 drives the lower pressure plate 9 and the probe assembly to reset, separating the probe assembly from the pins, allowing the operator to remove the tested power distribution terminal body 33. In this invention, the module carrier board 5 and the mounting plate 4 are detachably connected. By replacing the module carrier board 5, the corresponding test module 6 can be quickly replaced, making the test bench compatible with a variety of mainstream power distribution terminal models, reducing equipment investment costs. Furthermore, replacing the module carrier board 5 only requires operating the connection structure, which facilitates the rapid replacement of the module carrier board 5 and improves the efficiency of mixed testing of multiple models.

[0025] Example 2: Based on Example 1 above, clamping blocks 10 are symmetrically arranged on the front and rear sides of the placement hole 3. The left and right sides of the clamping blocks 10 are slidably connected to the inner wall of the placement hole 3. A sliding hole is arranged on one side away from each other of the two clamping blocks 10. A sliding column 11 is slidably arranged in the sliding hole. One end of the sliding column 11 is connected to the inner wall of the placement hole 3, and the other end of the sliding column 11 is connected to the inner wall of the sliding hole through the first spring 12. Two clamping blocks 10 are positioned close to each other on one side near the upper end, with a guide slope provided. The second electric push rod 13 is symmetrically arranged on the left and right sides of the placement base 2. The output end of the second electric push rod 13 extends into the placement hole 3 and is provided with a push block. The push block is located between the two clamping blocks 10.

[0026] The working principle and beneficial effects of the above technical solution are as follows: When the operator places the power distribution terminal body 33 into the placement hole 3, the bottom of the power distribution terminal body 33 first contacts the guide slope at the upper end of the clamping block 10, and presses the power distribution terminal body 33 downward. The bottom of the power distribution terminal body 33 slides downward along the guide slope, pushing the two clamping blocks 10 to slide away from each other. The first spring 12 is compressed until the bottom of the power distribution terminal body 33 contacts the bottom of the placement hole 3. The two clamping blocks 10 clamp the power distribution terminal body 33 into the placement hole 3. Then, one of the second electric push rods 13 is pushed out. The push out of the second electric push rod 13 can push the power distribution terminal body 33 to slide in the placement hole 3 through the push block, so that the pin part of the power distribution terminal body 33 is aligned with the probe assembly. Then the other The second electric push rod 13 extends until the push block contacts the outer wall of the power distribution terminal body 33, thereby limiting the sliding of the power distribution terminal body 33, improving the reliability of the power distribution terminal body 33, and ensuring that the power distribution terminal body 33 will not be displaced during the test. After the test is completed, the second electric push rod 13 is controlled to return to its original position, and the two push blocks separate from the outer wall of the power distribution terminal body 33 respectively, making it easy for the operator to take out the tested power distribution terminal body 33 from the placement hole 3. By setting the clamping block 10 and the push block in the placement hole 3, the placement hole 3 can be adapted to different models of power distribution terminal bodies 33 without replacing the placement seat 2, further reducing the equipment investment cost for testing multiple models of power distribution terminal bodies 33, and improving the positioning accuracy, avoiding poor contact between the probe assembly and the pins, and improving the accuracy of the test.

[0027] Example 3: Based on Example 1 or 2, the probe assembly includes a probe sleeve 14, a sliding block 15 is slidably disposed inside the probe sleeve 14, the sliding block 15 is connected to the top of the probe sleeve 14 by a second spring 16, and a probe rod 17 is disposed at the lower end of the sliding block 15, with the lower end of the probe rod 17 extending to the outside of the probe sleeve 14. The lower end of the probe rod 17 is a spherical contact end 18.

[0028] The working principle and beneficial effects of the above technical solution are as follows: After the power distribution terminal body 33 is placed into the placement hole 3 and fixed by the push block, the first electric push rod 8 is pushed down and drives the lower pressure plate 9 to move down. The probe assembly on the lower surface of the lower pressure plate 9 synchronously approaches the pin of the power distribution terminal body 33. When the spherical contact end 18 at the lower end of the probe rod 17 contacts the pin surface, it is electrically connected to the pin. The probe rod 17 that does not correspond to the pin slides into the probe sleeve 14 after contacting the outer wall of the power distribution terminal body 33. The probe rod 17 drives the sliding block 15 to slide in the probe sleeve 14. When the probe rod 17 is bent and broken, the second spring 16 is compressed, thus preventing the probe rod 17 from bending and breaking. This not only adapts to different models of power distribution terminal bodies 33, but also protects the probe rod 17, extends the service life of the probe assembly, and reduces maintenance costs. The lower end of the probe rod 17 contacts the pin through the spherical contact end 18. The spherical contact end 18 can increase the contact area and is compatible with mainstream pin shapes such as round and flat pins, forming a stable contact with the pin. Power distribution terminal bodies 33 with multiple types of pins can be tested without replacing the probe assembly, further expanding the multi-model adaptability of the test bench.

[0029] Example 4: Based on Example 3, the connecting mechanism includes a mounting hole 19, which is horizontally disposed within the mounting plate 4. A limiting ring 20 is disposed within the mounting hole 19. A fixing block 21 is disposed on the side of the module carrier plate 5 near the mounting plate 4. One end of the fixing block 21 extends into the mounting hole 19 and is disposed with a connecting block 22. Connecting holes 23 are symmetrically disposed on the upper and lower sides of the connecting block 22. A locking block 24 is slidably disposed within the connecting hole 23. The locking block 24 is connected to the inner wall of the connecting hole 23 by a third spring 25. An inclined surface 26 is disposed on the side of the locking block 24 away from the connecting hole 23. A conductive connecting piece 27 is disposed on the outer wall of the locking block 24. The conductive connecting piece 27 is electrically connected to the test module 6. The conductive connecting piece 27 is located between the inclined surface 26 and the fixing block 21. A conductive ring 28 corresponding to the conductive connecting piece 27 is embedded in the inner wall of the mounting hole 19. The probe rod 17 is electrically connected to the conductive ring 28 by a wire. The conductive connecting piece 27 abuts against the conductive ring 28 when the locking block 24 pops out. A drive cylinder 29 is installed inside the mounting hole 19. The drive cylinder 29 is located at the end of the mounting hole 19 away from the module carrier plate 5. The outer wall of the drive cylinder 29 is slidably connected to the inner wall of the mounting hole 19. A drive plate 30 is installed at the end of the drive cylinder 29 away from the module carrier plate 5. A fourth spring 31 is sleeved on the outside of the drive cylinder 29. One end of the fourth spring 31 is connected to the rear side wall of the mounting plate 4. The other end of the fourth spring 31 is connected to the drive plate 30. A chamfer 32 is provided on the inner wall of the drive cylinder 29 near the module carrier plate 5, and the chamfer 32 corresponds to the inclined surface 26.

[0030] The working principle and beneficial effects of the above technical solution are as follows: When installing the module carrier plate 5, first bring the module carrier plate 5 close to the mounting plate 4 so that the connecting block 22 is aligned with the mounting hole 19 of the mounting plate 4. Then, push the connecting block 22 into the mounting hole 19. The inclined surfaces 26 of the locking blocks 24 on the upper and lower sides of the connecting block 22 first contact the limiting ring 20 in the mounting hole 19. As the connecting block 22 continues to be pushed in, the inclined surfaces 26 are squeezed by the limiting ring 20, thereby pushing the locking blocks 24 to compress the third spring 25 and retract into the connecting hole 23 until the locking blocks 24 completely pass through the limiting ring 20. When the module carrier plate 5 contacts the mounting plate 4, the end face of the locking block 24 near the module carrier plate 5 is on the same plane as the end face of the limiting ring 20 away from the module carrier plate 5. At this time, the third spring Under the elastic force of 25, the locking block 24 slides away from the connecting hole 23. The end of the locking block 24 near the module carrier plate 5 is locked onto the end face of the limiting ring 20 away from the module carrier plate 5. At the same time, the conductive connecting piece 27 contacts the conductive ring 28 embedded in the inner wall of the mounting hole 19. The test module 6 is electrically connected to the conductive connecting piece 27. The conductive ring 28 is connected to an external power supply, thereby transmitting the working power required by the test module 6. The external power supply is set on the test bench body 1, and the conductive ring 28 is electrically connected to the probe rod 17. Therefore, a complete conductive link is formed between the test module 6, the conductive connecting piece 27, the conductive ring 28, and the probe rod 17, without the need for additional manual wiring. When it is necessary to replace the module carrier plate 5 of a different model of test module 6, the operator presses the drive towards the mounting plate 4. The moving plate 30 drives the driving cylinder 29 to slide within the mounting hole 19. The chamfer 32 at the end of the driving cylinder 29 near the module carrier plate 5 moves with the driving cylinder 29 and gradually contacts the inclined surface 26 of the locking block 24. The angle of the chamfer 32 is consistent with the angle of the inclined surface 26. Continuing to press the driving plate 30, the chamfer 32 can generate a pushing force on the inclined surface 26 towards the connection hole 23, thereby pushing the locking block 24 to slide into the connection hole 23. When the locking block 24 separates from the limiting ring 20, the locking of the locking block 24 and the limiting ring 20 is released. At this time, the module carrier plate 5 can be easily pulled out. Then, the driving plate 30 is released. Under the elastic force of the fourth spring 31, the driving plate 30 drives the driving cylinder 29 to return to its original position. By setting the connection mechanism, it is possible to install different test... The quick assembly and disassembly of the module carrier board 5 of module 6 improves replacement efficiency. Since the existing quick-release structure is prone to signal interruption under high-frequency vibration during batch testing, the conductive connecting piece 27 and the annular conductive ring 28 in this application are in spring-pressed surface contact. The third spring 25 can continuously provide stable contact pressure, ensuring the stability of mechanical locking and constant pressure of electrical contact, improving the reliability of the connection between the conductive connecting piece 27 and the conductive ring 28, solving the technical problem of poor contact caused by frequent switching of multiple models, avoiding pin wear and unstable contact impedance caused by frequent replacement of traditional plug-in interfaces, and ensuring the integrity of test signals through radial expansion surface contact, improving the stability of signal transmission, and ensuring accurate and reliable test results.
