[0003] The existing testing process is cumbersome. Each test requires operators to precisely fix the capacitor in the test position, complete the measurement, and then carefully remove it before installing a new capacitor for the next round of testing. This process not only consumes a lot of time and manpower, but the frequent installation and removal operations can also easily cause physical damage to the capacitor, affecting its electrical performance and thus greatly reducing the accuracy of the test results. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a device for testing the electrical performance of capacitors used in new energy vehicles. The specific technical solution is as follows:

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Example

[0022] Please refer to Figures 1-3 The electrical performance testing device for capacitors used in new energy vehicles of this utility model mainly consists of a test board 1, an electrical testing component 3, a clamping component, an adjustment component 4, and a moving component.

[0023] The test board 1 extends vertically, and one side surface has multiple placement slots 2 adapted to capacitors of different or the same specifications. These placement slots 2 are evenly distributed in a grid pattern. This layout design allows the test board 1 to accommodate multiple capacitors for testing simultaneously, greatly improving testing efficiency. The inner side of the placement slots 2 has lead through-holes 21 that pass through the test board 1, which facilitate the extension of capacitor leads for connection to subsequent electrical testing components 3.

[0024] The electrical testing assembly 3 includes a capacitance tester 33 and two opposing mounting plates 30. On the opposing sides of the two mounting plates 30, multiple first capacitance test pins 31 and multiple second capacitance test pins 32 are arranged laterally. The input terminals of the first capacitance test pins 31 and the second capacitance test pins 32 are connected to the capacitance tester 33 via conductive wires, and their contact terminals can be connected to conductive elastic metal components, such as conductive rubber pads or spring contacts. The placement of the conductive elastic metal components allows for better contact with the capacitor leads, ensuring stable transmission of the test signal and improving test accuracy.

[0025] The adjustment assembly 4 is used to drive the two sets of mounting plates 30 to move towards or away from each other, so as to adjust the contact position of the first capacitance test pin 31 and the second capacitance test pin 32 with the capacitor pins. The adjustment assembly 4 includes a housing 41, a drive motor 42 and a threaded rod 44.

[0026] The drive motor 42 is fixedly installed inside the housing 41 by bolts or welding, providing power for the entire adjustment process. One end of the threaded rod 44 is connected to the output shaft of the drive motor 42 via a coupling, and the other end is rotatably connected to the inside of the housing 41 via a bearing. Two sets of nut sleeves 43 are symmetrically threaded onto the threaded rod 44. One end of the mounting plate 30 extends movably into the housing 41 and is fixed to the nut sleeves 43 by welding or bolts. The capacitance tester 33 is mounted on the housing 41 by bolts or brackets, making the entire test assembly structure more compact.

[0027] The nut sleeve 43 has sliders on both sides, which are slidably connected to the grooves on the inner wall of the housing 41. This design effectively prevents the nut sleeve 43 from rotating during the rotation of the threaded rod 44, ensuring its stable axial movement along the threaded rod 44. The threaded rod 44 has two sets of threads with opposite directions, and the threads are adapted to the inner wall of the nut sleeve 43. In this way, when the threaded rod 44 rotates, the two sets of nut sleeves 43 can move in opposite directions, precisely controlling the spacing of the mounting plate 30.

[0028] The bottom of the test board 1 is fixed with a base 7 by welding or bolting. The base 7 provides stable support for the test board 1, ensuring the stability of the test board 1 throughout the test process and avoiding the impact of shaking on the test results.

[0029] The moving component includes a second electrically operated telescopic rod 8 mounted on the base 7. The fixed end of the second electrically operated telescopic rod 8 is connected to the base 7 by bolts or welding, and its output rod is connected to the housing 41 by bolts or connectors. By extending and retracting the second electrically operated telescopic rod 8, the electrical testing component 3 can be moved vertically to test the capacitors placed in the slot 2 at different heights.

[0030] A guide rod is fixed to the top of the base 7 by welding or bolting, and the top end of the guide rod moves through a guide hole on the housing 41. The guide rod serves as a guide, making the electrical test assembly 3 more stable during vertical movement, thereby improving the accuracy and reliability of the test.

[0031] The clamping assembly includes a movable component and multiple clamping plates 51 arranged vertically. The movable component includes a movable plate 5 and a first electric telescopic rod 6. The first electric telescopic rod 6 is mounted on the test plate 1 via a fixed bracket, which is connected to the test plate 1 by welding or bolts. The fixed end of the first electric telescopic rod 6 is connected to the fixed bracket by bolts or welding. The movable plate 5 is fixedly connected to the output rod of the first electric telescopic rod 6 by bolts or welding.

[0032] Multiple clamping plates 51 are fixedly connected to the movable plate 5 at the same end by welding or bolting. Each pair of clamping plates 51 forms a group, with one clamping plate 51 coaxially positioned on the top side of the placement groove 2 and the other coaxially positioned on the bottom side of the placement groove 2. When the first electric telescopic rod 6 is activated, it drives the movable plate 5 to move, thereby moving the clamping plates 51 closer to or further away from the placement groove 2, achieving stable clamping of the capacitor, preventing displacement of the capacitor during testing, and ensuring the accuracy of the test results.

[0033] An insulating buffer pad is fixed to the side of the clamping plate 51 near the placement slot 2 by adhesive or snap-fit. The insulating buffer pad can be made of rubber or silicone, etc. The insulating buffer pad not only prevents the clamping plate 51 from directly contacting the capacitor and causing scratch damage, but also provides insulation to prevent safety hazards such as leakage during testing. At the same time, it can also increase the stability of clamping and further improve the reliability of testing.

[0034] Before testing, the operator places multiple capacitors to be tested into their respective placement slots 2, with the capacitor leads extending through the lead ports 21. Next, the controller activates the first electric telescopic rod 6. The output rod of the first electric telescopic rod 6 moves the movable plate 5, causing multiple clamping plates 51 to approach the placement slots 2, clamping and securing the capacitors to ensure they do not shift during testing.

[0035] At the start of the test, the second electric telescopic rod 8 is activated by the controller. The output rod of the second electric telescopic rod 8 pushes the housing 41 to move upward, causing the electrical test assembly 3 to rise as a whole, so that the multiple first capacitance test pins 31 and second capacitance test pins 32 inside the electrical test assembly 3 are coaxially aligned with the pins of the capacitors located on the top layer of the test board 1.

[0036] Then, the drive motor 42 in the adjustment assembly 4 is activated. The drive motor 42 drives the threaded rod 44 to rotate, causing the two sets of nut sleeves 43 to move towards each other on the threaded rod 44. This, in turn, causes the two sets of mounting plates 30 to move towards each other, so that the first capacitance test pin 31 and the second capacitance test pin 32 come into contact with the leads on both sides of the capacitor. At this time, the capacitance tester 33 starts working and tests the electrical performance of the capacitor. After the test is completed, the drive motor 42 reverses, causing the two sets of mounting plates 30 to move away from each other, so that the first capacitance test pin 31 and the second capacitance test pin 32 separate from the capacitor leads. Next, the second electric telescopic rod 8 is activated again, causing the electrical testing assembly 3 to move downwards, so that the first capacitance test pin 31 and the second capacitance test pin 32 are aligned with the capacitor leads of the next row of the test plate 1. The above test steps are repeated until all capacitors are tested.

[0037] After the test is completed, the first electric telescopic rod 6 is controlled by the controller to move the clamping plate 51 away from the placement slot 2, thus releasing the clamp on the capacitor. Then, the operator removes the tested capacitor, cleans the placement slot, and prepares for the next batch of tests.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
