[0028] Example 1

[0029] like Figure 1-8 As shown, a capacitor withstand voltage performance testing device includes a testing housing 1, a clamping component for positioning the capacitor is provided inside the testing housing 1, a communicating component fixed to the leads of the capacitor is provided inside the testing housing 1, the clamping component and the communicating component are fixedly connected, a tester 23 is provided at the lower end of the testing housing 1, and the communicating component is electrically connected to the tester 23 through a connecting line 24.

[0030] The working principle of the above technical solution is as follows: Multiple capacitors of the same or different specifications can be placed on the detection housing 1, and the capacitors are fixed by the clamping component. The capacitors are electrically connected to the detector 23 through the connecting component and the connecting line 24. The detector 23 tests the withstand voltage performance of the capacitors.

[0031] Example 2

[0032] like Figure 1-8 As shown, the clamping component includes a pull rod 2, which slides inside the detection housing 1. Both ends of the pull rod 2 are fixedly connected to two triangular pushers 3, and the triangular pushers 3 and 4 are slidably connected. Both the triangular pushers 3 and 4 slide inside the detection housing 1.

[0033] One end of the triangular pusher 4 is fixed to the push rod 5, and the other end of the triangular pusher 4 is fixed to the push rod 11. The front end of the push rod 5 is rotatably connected to the bent rod 6, one end of the bent rod 6 is rotatably connected to the double ball stick 7, and the other end of the bent rod 6 is rotatably connected to the double ball stick 10.

[0034] The two ends of the double ball rod 7 respectively abut against the two clamping rods 8, and the two ends of the double ball rod 10 respectively abut against the two clamping rods 8. The clamping rods 8 are slidably connected to the detection housing 1, and a spring 9 is provided between the clamping rods 8 and the detection housing 1.

[0035] The push rod 2 11 is rotatably connected to the bent rod 2 12. One end of the bent rod 2 12 is rotatably connected to the double ball stick 3 13. The other end of the bent rod 2 12 abuts against the bent rod 1 6. The two ends of the double ball stick 3 13 abut against the two clamping rods 8 respectively.

[0036] The working principle of the above technical solution is as follows: The capacitor is placed on the connecting block 14 on the outer casing 1, with the two leads of the capacitor located on both sides of the connecting block 14. Pushing the pull rod 2 causes the triangular pusher 3 to move forward. The triangular pusher 3 presses against the triangular pusher 4, causing push rods 5 and 11 to slide on the detection casing 1. This causes bent rods 6 and 12 to move forward, leading to the movement of double ball rods 7, 10, and 13, which in turn press against the six clamping rods 8, causing spring 9 to move forward. When compressed, the clamping rods 8 can hold the capacitor. Since the push rod 1 5 and the bent rod 1 6 can rotate, the push rod 2 11 and the bent rod 2 12 can rotate, the bent rod 1 6 and the double ball rod 1 7 can rotate, the bent rod 1 6 and the double ball rod 2 10 can rotate, and the bent rod 2 12 and the double ball rod 3 13 can rotate, the six clamping rods 8 can move forward by different lengths according to the different specifications of the capacitors, thus clamping capacitors of different specifications, which is highly adaptable.

[0037] Example 3

[0038] like Figure 1-8 As shown, the detection housing 1 has a long groove 15 inside, and six connecting blocks 14 are provided in the long groove 15. An insulating block 16 is fixed on the connecting block 14.

[0039] The working principle of the above technical solution is as follows: The capacitor is placed on the connecting block 14 on the outer shell 1, and the two leads of the capacitor are located on both sides of the connecting block 14. An insulating block 16 is fixed on the connecting block 14, and the insulating block 16 can prevent the two leads from accidentally contacting each other.

[0040] Example 4

[0041] like Figure 1-8 As shown, the connecting component includes a first sliding plate 17 and a second sliding plate 18. Both the first sliding plate 17 and the second sliding plate 18 slide within the detection housing 1. The first sliding plate 17 is fixedly connected to the pull rod 2.

[0042] The first slide plate 17 and the second slide plate 18 are both provided with support plates 19. The support plates 19 are fixedly connected to the metal plates 21 by springs 20. Both metal plates 21 are electrically connected to the detector 23 by connecting wires 24.

[0043] The bottom of the first slide plate 17 and the second slide plate 18 are both provided with racks, and both racks mesh with gears 22 for transmission. Gears 22 are rotatably connected to the detection housing 1.

[0044] The working principle of the above technical solution is as follows: After the capacitor is placed on the connecting block 14, the two leads of the capacitor are located on both sides of the insulating block 16. Pushing the pull rod 2 will cause the clamping component to clamp the capacitor. The pull rod 2 moves forward, causing the first slide plate 17 to slide forward in the detection housing 1, which in turn causes the support plate 19 on the first slide plate 17 to move towards the leads of the capacitor, which in turn causes the spring 20 and the metal plate 21 to move towards the leads of the capacitor. The first slide plate 17 slides forward in the detection housing 1, which causes the gear 22 to rotate, which in turn causes the second slide plate 18 to move in the detection housing 1, which in turn causes the support plate 19 on the second slide plate 18 to move towards the leads of the capacitor, which in turn causes the two metal plates 21 to move towards each other. The two metal plates 21 are electrically connected to the two leads of the capacitor, and the capacitor is then connected to the detector 23 through the metal plates 21 and the connecting wire 24.

[0045] Pushing the lever 2 allows for simultaneous clamping and energizing of the capacitor, resulting in strong linkage. Additionally, the metal plate 21 clamps and contacts the capacitor leads, preventing bending or damage to the capacitor leads during testing, as is done with traditional capacitor insertion methods.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
