DETAILED DESCRIPTION

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] It is understandable that, referring to Figures 1 to 5 The utility model provides a capacitor withstand voltage detection device, including a testing mechanism 200 and a slide 220. The testing mechanism 200 includes a pressing plate 210, multiple withstand voltage testers 230 and multiple power supplies 240. Multiple groups of first test electrodes 211 are provided at the bottom of the pressing plate 210. Each group of first test electrodes 211 is electrically connected to a withstand voltage tester 230, and each power supply 240 is electrically connected to at least one withstand voltage tester 230. The slide 220 is located below the pressing plate 210. The slide 220 is provided with a clamp 300. The clamp 300 is used to fix the capacitor. The clamp 300 is provided with multiple groups of electrode groups 340 for electrically connecting the core. Multiple groups of second test electrodes 223 are provided on the top of the slide 220. Each group of second test electrodes 223 is electrically connected to a group of electrode groups 340. The second test electrodes 223 correspond to the first test electrodes 211 one by one. The pressing plate 210 can move toward the slide 220 so that the first test electrodes 211 can abut against the second test electrodes 223.

[0029] When in use, the capacitor is fixed to the fixture 300, and different cores are electrically connected through multiple groups of electrode groups 340. Since each group of second test electrodes 223 is electrically connected to a group of electrode groups 340, each core is electrically connected to a group of second test electrodes 223. The pressure plate 210 is moved toward the direction close to the slide 220 so that the first test electrode 211 abuts the second test electrode 223. Since a group of first test electrodes 211 is electrically connected to a withstand voltage tester 230, each power supply 240 is electrically connected to at least one withstand voltage tester 230, so that each core can be electrically connected to a withstand voltage tester 230, and withstand voltage tests can be performed on multiple cores at the same time to improve detection efficiency. Different power supplies 240 can be used for charging tests as needed to meet different testing requirements.

[0030] It should be noted that during the voltage withstand test, it is necessary to apply voltage to the core through the power supply 240 for charging. Different types of cores require different voltages to be applied, or different types of currents need to be provided, so different power supplies 240 need to be connected to the circuit.

[0031] The power supply 240 can be an AC power supply 240 or a DC power supply 240. Since multiple power supplies 240 are provided, different types of power supplies 240 can be selected as needed to connect to the circuit for testing to meet different testing requirements.

[0032] The clamp 300 is detachably connected to the slide 220 , and different clamps 300 can be removed and replaced according to different types of capacitors to meet the positioning requirements of different types of capacitors.

[0033] A frame 100 can be set up, and the frame 100 is provided with a first driving member 400 and a second driving member 500, and the pressure plate 210 and the slide 220 are slidably connected to the frame 100. The first driving member 400 and the second driving member 500 can both be cylinders, oil cylinders or linear slide modules, etc. The first driving member 400 drives the slide 220 to move horizontally to the bottom of the pressure plate 210, and the second driving member 500 drives the pressure plate 210 to move vertically toward the direction close to the slide 220, which can improve the test efficiency and stability.

[0034] It is understandable that, referring to Figure 2 and Figure 4 The fixture 300 includes a first slider 310, which is mounted on the slide 220 and has a positioning slot 311 for securing the capacitor. Since the first slider 310 is mounted on the slide 220 and has the positioning slot 311, securing the capacitor through the positioning slot 311 improves the capacitor's positional stability, reduces contact problems caused by capacitor shaking, and thus improves test stability.

[0035] Specifically, refer to Figure 2 and Figure 4 The first slider 310 has four right-angled positioning blocks 312 at the four corners of its upper end. These four right-angled positioning blocks 312 enclose a positioning slot 311. The four right-angled positioning blocks 312 engage and limit the capacitor's position from its four corners, thereby improving its positional stability and reducing its contact area with the capacitor, thereby minimizing collision damage to the capacitor.

[0036] Specifically, refer to Figures 3 to 5 The fixture 300 also includes a second slider 320 and a first bracket 330. The first bracket 330 is fixedly connected to the slide 220. The electrode group 340 includes a first electrode rod 341 and a second electrode rod 343. The first electrode rod 341 is connected to the first bracket 330, and the second electrode rod 343 is connected to the second slider 320. The second slider 320 is slidably connected to the slide 220. The second slider 320 can move toward the direction close to the first bracket 330 so that the second electrode rod 343 can abut the electrode of the core. Since the second slider 320 is slidably connected to the slide 220, the second slider 320 is first moved in a direction away from the first bracket 330, driving the second electrode rod 343 away from the first electrode rod 341, so that an avoidance space is formed between the second electrode rod 343 and the first electrode rod 341, which can facilitate the installation of the capacitor in the positioning groove 311. Then, the second slider 320 is moved in a direction close to the first bracket 330 so that the second electrode rod 343 abuts the electrode of the core, which can control the abutting force between the second electrode rod 343 and the core electrode, thereby improving the contact stability.

[0037] It should be noted that, after the second slider 320 moves to a preset position in a direction close to the first bracket 330 , it can be positioned by fasteners such as a latch or a bolt 370 .

[0038] Specifically, refer to Figures 3 to 5The first electrode rod 341 is slidably connected to the first bracket 330. A first abutting portion 342 is provided at the end of the first electrode rod 341 facing the second electrode rod 343. A first spring 350 is mounted on the first electrode rod 341, with both ends of the first spring 350 connected to the first bracket 330 and the first abutting portion 342, respectively. Because the first electrode rod 341 is mounted with the first spring 350, and its two ends are connected to the first bracket 330 and the first abutting portion 342, respectively, when the capacitor is mounted in the positioning slot 311, the first abutting portion 342 abuts against the core electrode and pushes the first abutting portion 342 toward the first bracket 330, compressing and deforming the first spring 350. The compressed first spring 350 elastically drives the first abutting portion 342 to abut against the core electrode, forming an elastic abutment. This reduces the possibility of collision damage when the first abutting portion 342 abuts against the core electrode and improves contact stability.

[0039] Specifically, refer to Figures 3 to 5 The second slider 320 is connected to the second bracket 321, the second electrode rod 343 is slidably connected to the second bracket 321, and a second abutment portion 344 is provided at the end of the second electrode rod 343 facing the first electrode rod 341. The second electrode rod 343 is fitted with a second spring 360, and the two ends of the second spring 360 are respectively connected to the second bracket 321 and the second abutment portion 344. Since the second electrode rod 343 is equipped with a second spring 360, the two ends of the second spring 360 are respectively connected to the second bracket 321 and the second abutting portion 344. When the second slider 320 moves toward the first bracket 330, the second abutting portion 344 abuts against the electrode of the core. The reaction force of the electrode of the core on the second abutting portion 344 pushes the second abutting portion 344 toward the second bracket 321, causing the second spring 360 to be compressed and deformed. The compressed second spring 360 elastically drives the second abutting portion 344 to abut against the electrode of the core, forming an elastic abutment, which can reduce the possibility of collision damage when the second abutting portion 344 abuts against the core electrode and improve the contact stability.

[0040] Specifically, refer to Figure 4 and Figure 5 The first slider 310 is slidably connected to the slider 220, and the second slider 320 can abut the first slider 310 and drive the first slider 310 toward the first bracket 330. Since the first slider 310 is slidably connected to the slider 220, by moving the first slider 310 away from the first bracket 330, the capacitor can be easily mounted in the positioning groove 311, reducing the possibility of the capacitor colliding with the first bracket 330 during placement in the positioning groove 311. After the capacitor is placed, the second slider 320 abuts the first slider 310 and drives the first slider 310 toward the first bracket 330, causing the first electrode rod 341 to abut the core electrode, thereby improving contact stability.

[0041] It should be noted that the first slider 310 may be driven to move in a direction away from the first bracket 330 by a spring return mechanism, so that the first slider 310 can be quickly returned to its original position.

[0042] When the first slider 310 moves to a preset position, it can be positioned by fasteners such as pins or bolts.

[0043] Specifically, refer to Figure 4 and Figure 5 The slide 220 is provided with a limit block 224 that can abut against the first slider 310 to limit the movement of the first slider 310 toward the first bracket 330. The limit block 224 abuts against the first slider 310 to limit the movement of the first slider 310 toward the first bracket 330. This reduces the possibility of the first electrode rod 341 damaging the capacitor due to excessive movement of the first slider 310, thereby improving the stability of the capacitor positioning.

[0044] Specifically, refer to Figure 4 and Figure 5 The second slider 320 defines a positioning hole 322 through which a bolt 370 is passed. The second slider 320 is fixedly connected to the slide base 220 via the bolt 370. Because the second slider 320 defines the positioning hole 322 through which the bolt 370 is passed, when the second slider 320 abuts against the first slider 310 and drives the first slider 310 to move toward the first bracket 330 to a predetermined position, the bolt 370 is tightened to secure the second slider 320 to the slide base 220. This allows the second slider 320 to cooperate with the stop block 224 to clamp and secure the position of the first slider 310, thereby improving the positional stability of the first slider 310 and thereby improving the positioning stability of the capacitor.

[0045] Specifically, refer to Figures 1 to 5 The slide 220 is provided with a first guide rail 221. The first guide rail 221 is arranged in a horizontal direction close to the first bracket 330, and the second slider 320 is slidably connected to the first guide rail 221. Since the first guide rail 221 is arranged in a horizontal direction close to the first bracket 330, the second slider 320 is slidably connected to the first guide rail 221. The first guide rail 221 guides the second slider 320 in a horizontal direction close to the first bracket 330, which can improve the stability of the movement of the second slider 320.

[0046] It should be noted that the slide 220 can be provided with a second guide rail 222, which is arranged in a horizontal direction close to the first bracket 330. The first slider 310 is slidably connected to the second guide rail 222. The second guide rail 222 guides the first slider 310 to move in a horizontal direction close to the first bracket 330, thereby improving the stability of the movement of the first slider 310.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
