[0002] Capacitor leads are an important component of capacitors, typically made of metal. Their primary function is to provide electrical connection between the capacitor and external circuits, linking the capacitor's internal electrodes to other components in the circuit, allowing current to flow smoothly. Simultaneously, the leads must possess sufficient mechanical strength and stability to prevent easy deformation or damage during capacitor installation and use, ensuring the capacitor functions properly and fulfills its functions of storing and releasing electrical energy in electronic devices. The purpose of capacitor lead pressure testing devices is to simulate actual operating conditions and test the leads' ability to withstand pressure, ensuring they meet quality standards and usage requirements.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-14The device shown is a pressure testing device for capacitor leads, comprising a pressure testing instrument 1, a fixed frame 2 fixedly connected to the top of the pressure testing instrument 1, a hydraulic cylinder 3 fixedly connected to the top of the fixed frame 2, a pressure sensor 4 fixedly connected to the output end of the hydraulic cylinder 3, a direction adjustment mechanism 5 provided at the bottom of the pressure sensor 4 for direction adjustment, an angle adjustment mechanism 6 rotatably connected to the bottom of the direction adjustment mechanism 5 for angle adjustment, a clamping mechanism 7 provided at the bottom of the angle adjustment mechanism 6 for clamping the capacitor lead, a disassembly and assembly mechanism 8 provided at the top of the pressure testing instrument 1, a chassis 9 fixedly connected to the top of the disassembly and assembly mechanism 8 for... For installing and removing the chassis 9, after the chassis 9 and the capacitor guide pin are installed, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 extends and drives the pressure sensor 4, the direction adjustment mechanism 5, the angle adjustment mechanism 6, and the clamping mechanism 7 to move downward. This causes the capacitor guide pin to move downward and press against the chassis 9, thereby continuously applying pressure to the capacitor. The pressure sensor 4 detects the pressure, thus completing the pressure resistance test of the capacitor guide pin. The angle adjustment mechanism 6 can be used to change the angle of the capacitor guide pin to test the pressure resistance of the capacitor guide pin at different angles. At the same time, the direction adjustment mechanism 5 can be used to change the direction of the capacitor guide pin to test the pressure resistance of the capacitor guide pin in different directions.

[0022] The direction adjustment mechanism 5 includes a rotating column 501, which provides the installation position and conditions. The top of the rotating column 501 is rotatably connected to the bottom of the pressure sensor 4. A mounting frame 502 is fixedly connected to the bottom of the rotating column 501, providing the installation position. A bottom sleeve 503 is fixedly connected to the top of the mounting frame 502, providing the installation position. A push spring 504 is provided inside the bottom sleeve 503, and a limit ring 505 is slidably connected inside the bottom sleeve 503. The limiting ring 505 has a limiting function. A movable sleeve 508 is fixedly connected to the top of the limiting ring 505, serving a connecting function. Multiple insertion rods 509 are fixedly connected to the top of the movable sleeve 508. A fixing ring 510 is fixedly connected to the bottom of the pressure sensor 4. Multiple insertion holes 511 are opened inside the fixing ring 510. After the insertion rods 509 are inserted into the insertion holes 511, the mounting frame 502 is prevented from rotating further. The insertion rods 509 and insertion holes 511 engage. The limiting ring 505... Multiple limiting grooves 506 are provided on the outer side, and multiple limiting rods 507 are fixedly connected to the inner wall of the bottom sleeve 503. The cooperation between the limiting rods 507 and the limiting grooves 506 can prevent the movable sleeve 508 from rotating. The limiting rods 507 are slidably connected inside the limiting grooves 506. One end of the push spring 504 is fixedly connected to the bottom of the limiting ring 505, and the other end of the push spring 504 is fixedly connected to the bottom of the inner side of the bottom sleeve 503. When detecting a change in the direction of the capacitor lead needle, the movable sleeve 508 is first moved... Pulling it downwards moves the plug 509 out of the socket 511. At this point, the mounting frame 502 can be rotated, changing the direction of the capacitor pin. After the direction is changed, the movable sleeve 508 is released. Under the reaction force of the push spring 504, the limiting ring 505 moves upward, which in turn moves the movable sleeve 508 and the plug 509 upward, allowing the plug 509 to be reinserted into the socket 511, thus completing the change of the capacitor pin direction.

[0023] The angle adjustment mechanism 6 includes a rotating sleeve 601, which provides the mounting position. The middle part of the rotating sleeve 601 is rotatably connected to the inside of the mounting frame 502. A rotating retaining ring 602 is fixedly connected to one end of the rotating sleeve 601, and a retaining spring 603 is fixedly connected to the inside of the other end of the rotating sleeve 601. A fixed retaining ring 604 is fixedly connected to the inner side of one end of the mounting frame 502. The retaining spring 603 uses its own reaction force to cause the rotating sleeve 601 and the rotating retaining ring 602 to move towards the fixed retaining ring 604. The rotating sleeve 601 moves and engages with the fixed sleeve 604. This engagement locks the rotating sleeve 601, preventing it from rotating. A connecting rod 605 is fixedly connected to the bottom of the rotating sleeve 601, serving as a connector. The end of the spring 603 furthest from the rotating sleeve 601 is rotatably connected to the mounting frame 502 furthest from the fixed sleeve 604. On one side, the retaining spring 603 is inserted inside the mounting frame 502. When changing the angle of the capacitor lead, the rotating sleeve 601 is moved away from the fixed retaining ring 604, which in turn drives the rotating retaining ring 602 away from the fixed retaining ring 604. This releases the engagement between the rotating retaining ring 602 and the fixed retaining ring 604, and the rotating sleeve 601 compresses the retaining spring 603. At this point, the rotating sleeve 601 can be rotated, and after the rotating sleeve 601 rotates, it can drive the connecting... The connecting rod 605 rotates, which drives the clamping mechanism 7 to rotate, and then drives the capacitor guide needle to rotate. After the capacitor guide needle has rotated to the correct angle, the rotating sleeve 601 can be released. After the rotating sleeve 601 is released, the clamping spring 603 can push the rotating sleeve 601 and the rotating retaining ring 602 to move towards the fixed retaining ring 604, so that the rotating retaining ring 602 and the fixed retaining ring 604 can re-engage, thereby changing and locking the angle of the capacitor guide needle.

[0024] The clamping mechanism 7 includes a mounting cylinder 701, which provides a mounting position. The top of the mounting cylinder 701 is fixedly connected to the bottom of the connecting rod 605. Multiple mounting slots 702 are provided inside the mounting cylinder 701. A rotating arm 703 is rotatably connected inside the mounting slots 702. A clamping block 704 is fixedly connected to the inner side of the rotating arm 703. The clamping block 704 can press against or release the capacitor lead when the rotating arm 703 rotates. A rotating ring 706 is rotatably connected to the outside of the mounting cylinder 701, providing a mounting position. An abutment block 707 is fixedly connected inside the rotating ring 706. The abutment block 707 can abut against the outer side of the rotating arm 703, thereby driving the rotating arm 703. 03. The mounting cylinder 701 is externally threaded with a threaded ring 709. Tightening the threaded ring 709 allows it to move up or down on the mounting cylinder 701. Moving it upwards removes the threaded ring 709 from the top of the rotating ring 706, while moving it downwards abuts against the top of the rotating ring 706, preventing it from rotating again and locking it. A spring piece 705 is fixedly connected between the inner side of the rotating arm 703 and the inner wall of the mounting cylinder 701. The spring piece 705 can reset the rotating arm 703. Multiple rotating handles 708 are fixedly connected to both the threaded ring 709 and the outer side of the rotating ring 706, facilitating the rotation of the threaded ring by the operator. When clamping the capacitor lead using the threaded ring 709 and rotating ring 706, first, screw the threaded ring 709 upwards. This moves the threaded ring 709 away from the top of the rotating ring 706. Then, rotate the rotating ring 706. The rotation of the rotating ring 706 causes the abutment block 707 to rotate away from the spring piece 705. Under the action of the spring piece 705, the rotating arm 703 and clamping block 704 rotate into the mounting groove 702. The capacitor lead is then placed between the clamping blocks 704. Next, rotate the rotating ring 706, which moves the abutment block 707 closer to the spring piece 705. At this point, the rotating arm 703... 3. Under the abutment of the abutment block 707, the clamping block 704 can be brought together in the middle, and then the capacitor lead pin can be clamped by the clamping block 704. At this time, the threaded ring 709 is twisted in the opposite direction to move the threaded ring 709 downward, and then the threaded ring 709 can be used to press against the rotating ring 706 to prevent the rotating ring 706 from rotating, thereby completing the installation of the capacitor lead pin. When disassembling, the threaded ring 709 is rotated directly so that the bottom of the threaded ring 709 leaves the top of the rotating ring 706, and the rotating ring 706 is rotated so that the rotating arm 703 can rotate in the direction of the mounting groove 702 under the action of the spring piece 705, thereby releasing the clamping of the capacitor lead pin, and then the capacitor lead pin can be disassembled.

[0025] The disassembly / assembly mechanism 8 includes a sliding connecting block 801, which provides an installation position. Two mounting slots 802 are formed inside the sliding connecting block 801, providing installation space. A return spring 803 is installed inside each mounting slot 802. A limiting block 804 is slidably connected inside the mounting slot 802, serving a limiting function. A locking head 805 is fixedly connected to the end of the limiting block 804 away from the return spring 803. A pull handle 806 is fixedly connected to the outside of the limiting block 804, allowing it to... The limiting block 804 moves. Two through slots 807 are formed inside one side of the sliding connecting block 801, providing sliding space for the pull handle 806. The pull handle 806 is slidably connected to the inside of the through slots 807. Two engaging holes are formed inside the top of the pressure testing instrument 1, and the engaging head 805 engages with these holes. A sliding groove 808 is formed inside the pressure testing instrument 1, and the sliding connecting block 801 is slidably connected inside the sliding groove 808. One end of the return spring 803 is fixedly connected to the inside of the receiving groove 802. The other end of 03 is fixedly connected to the inner side of the limiting block 804. The interior of the through groove 807 is connected to the interior of the housing groove 802. The bottom of the chassis 9 is fixedly connected to the top of the sliding connecting block 801. When installing the chassis 9, first pull the pull handle 806 towards the center, which will drive the limiting block 804 to move towards the center. Then, the locking head 805 will retract into the housing groove 802. At this time, the sliding connecting block 801 can be slid into the sliding groove 808. Release the pull handle 806, and under the action of the return spring 803, it can move the chassis 9. The movable limit block 804 and the engaging head 805 move outward, thereby engaging the engaging head 805 with the engaging hole, completing the installation of the sliding connecting block 801, and then completing the installation of the chassis 9. When disassembling the chassis 9, the pull handle 806 is pulled towards the center, thereby moving the limit block 804 and the engaging head 805 towards the center, thereby disassembling the engaging head 805 from the engaging hole inside the pressure tester 1. At this time, the sliding connecting block 801 can be pulled out from inside the sliding groove 808, thus completing the disassembly of the chassis 9.

[0026] Working principle: When changing the direction of the capacitor lead, first pull the movable sleeve 508 downward, so that the insertion rod 509 can be moved out of the socket 511. At this time, the mounting frame 502 can be rotated, thereby changing the direction of the capacitor lead. After the direction is changed, the movable sleeve 508 is released. At this time, under the reaction force of the push spring 504, the limiting ring 505 is moved upward, which can drive the movable sleeve 508 and the insertion rod 509 to move upward, and then the insertion rod 509 can be re-inserted into the socket 511, completing the change of the direction of the capacitor lead.

[0027] When changing the angle of the capacitor guide pin, the rotating sleeve 601 is moved away from the fixed retaining ring 604, which in turn moves the rotating retaining ring 602 away from the fixed retaining ring 604. This releases the engagement between the rotating retaining ring 602 and the fixed retaining ring 604, and the rotating sleeve 601 compresses the clamping spring 603. The rotating sleeve 601 can then be rotated, which in turn drives the connecting rod 605 to rotate, thereby driving the clamping mechanism 7 to rotate. This, in turn, drives the capacitor guide pin to rotate. Once the capacitor guide pin has rotated to the correct angle, the rotating sleeve 601 can be released. After the rotating sleeve 601 is released, the clamping spring 603 pushes the rotating sleeve 601 and the rotating retaining ring 602 towards the fixed retaining ring 604, allowing the rotating retaining ring 602 to re-engage with the fixed retaining ring 604, thus changing and locking the angle of the capacitor guide pin. When clamping the capacitor lead, first tighten the threaded ring 709 to move it upwards. This prevents the threaded ring 709 from pressing against the top of the rotating ring 706. Then, rotate the rotating ring 706. The rotation of the rotating ring 706 causes the abutment block 707 to rotate away from the spring piece 705. Under the action of the spring piece 705, the rotating arm 703 and the clamping block 704 rotate towards the mounting groove 702. The capacitor lead is then placed between the clamping blocks 704. Next, rotate the rotating ring 706 again, causing the abutment block 707 to move closer to the spring piece 705. At this point, the rotating arm 703 is positioned between the abutment block 704 and the spring piece 705. The abutment of 07 causes the clamping block 704 to converge towards the center, thereby clamping the capacitor lead pin. At this time, the threaded ring 709 is twisted in the opposite direction to move it downwards, thereby pressing the rotating ring 706 against it to prevent it from rotating, thus completing the installation of the capacitor lead pin. When disassembling, the threaded ring 709 is rotated directly so that the bottom of the threaded ring 709 leaves the top of the rotating ring 706, and the rotating ring 706 is rotated so that the rotating arm 703 can rotate towards the mounting groove 702 under the action of the spring piece 705, thereby releasing the clamping of the capacitor lead pin and allowing the capacitor lead pin to be disassembled. When installing chassis 9, first pull the handle 806 towards the center, which moves the limiting block 804 towards the center, causing the engaging head 805 to retract into the mounting groove 802. Then, the sliding connecting block 801 can be slid into the sliding groove 808. Release the handle 806; under the action of the return spring 803, the limiting block 804 and the engaging head 805 will move outwards, causing the engaging head 805 to engage with the engaging hole, completing the installation of the sliding connecting block 801 and thus completing the installation of chassis 9. When removing chassis 9, similarly, pull the handle 806 towards the center, which moves the limiting block 804 and the engaging head 805 towards the center, causing the engaging head 805 to disengage from the pressure testing instrument 1. In the engaging hole, the sliding connecting block 801 can be pulled out from the inside of the sliding groove 808, thus completing the disassembly of the chassis 9. After the chassis 9 and the capacitor guide pin are installed, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 extends and drives the pressure sensor 4, the direction adjustment mechanism 5, the angle adjustment mechanism 6, and the clamping mechanism 7 to move downward, thereby driving the capacitor guide pin to move downward and press against the chassis 9, thus continuously applying pressure to the capacitor. The pressure sensor 4 detects the pressure, thereby completing the pressure resistance test of the capacitor guide pin. The angle adjustment mechanism 6 can be used to change the angle of the capacitor guide pin to detect the pressure resistance of the capacitor guide pin at different angles. At the same time, the direction adjustment mechanism 5 can be used to change the direction of the capacitor guide pin, thereby detecting the pressure resistance of the capacitor guide pin in different directions.
