Description

Technical Field

[0001] This utility model relates to the field of capacitor disassembly and assembly technology, specifically to a quick-change buckle device for aluminum electrolytic capacitors. Background Technology

[0002] Aluminum electrolytic capacitors are made by inserting a bent aluminum strip as the positive electrode into an aluminum cylinder containing a liquid electrolyte, with the cylinder serving as the negative electrode. They also require DC voltage treatment to form an oxide film on the positive electrode as the dielectric. Their characteristics include large capacitance, but also high leakage current, poor stability, and polarity. They are suitable for power supply filtering or low-frequency circuits. Current capacitor installation methods typically involve manually holding the capacitor and connecting the positive and negative terminals to the circuit board, then fixing it with solder. This method is inefficient, and replacement requires manual removal, which is cumbersome. To improve capacitor replacement, a quick-replacement clip device for aluminum electrolytic capacitors is proposed.

[0003] As disclosed in CN209912721U, a quick-installation bracket for capacitors includes a base plate with a first threaded hole. A side plate is fixedly connected to the base plate. A buckle is provided on the side of the side plate away from the first threaded hole. A first buckle portion of the buckle is fixedly connected to the side plate, and a second buckle portion is fixedly connected to the first buckle portion. The first and second buckle portions form an "L"-shaped structure. The second buckle portion, the first buckle portion, and the side plate form an opening facing the base plate. A connecting portion is provided on the side of the side plate away from the base plate. The capacitor to be installed fits into the first threaded hole and abuts against the side plate and the base plate. The buckle is fastened to an external device, and the connecting portion is fixedly connected to the external device.

[0004] Although it achieves the goal of firmly fixing the bracket to the external device and then installing the capacitor on the external device, it is evident that the bracket can be easily installed on the external device and can also be easily removed from the external device. The installation and removal efficiency is high, and the capacitor is fixed relatively securely.

[0005] However, the existing snap-fit ​​device does not solve the problem that it is not conducive to the quick installation and removal of capacitors when using the linkage center to clamp the capacitor, nor is it conducive to the use of capacitors on circuit boards of different sizes, thus affecting the convenience and flexibility of capacitor installation and removal. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-change buckle device for aluminum electrolytic capacitors, so as to solve the problem mentioned in the background art that the buckle device is not convenient for clamping the capacitor in the linkage center to quickly disassemble and replace the capacitor, and is not conducive to the adaptation of capacitors on circuit boards of different sizes, thus affecting the convenience and flexibility of capacitor disassembly and replacement.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A quick-change buckle device for aluminum electrolytic capacitors includes a top plate and a sleeve. The sleeve is movably mounted on the top of the top plate, and a hand handle is mounted on the top of the top plate outside the sleeve. A threaded sleeve is provided on the top of the sleeve, and a lead screw is provided inside the threaded sleeve and threadedly connected to the threaded sleeve. A toothed ring is provided on the outer wall of the threaded sleeve, and a rack is provided inside the hand handle on one side of the toothed ring. Limiting strips are provided at both the upper and lower ends of the rack, and the rack is slidably connected to the hand handle through the limiting strips. A pressing block is provided at one end of the rack, and sliding rods are symmetrically provided on the side wall of the pressing block.

[0009] Optionally, the slide bar extends into the interior of the hand grip and is slidably connected to the hand grip, and the surface of the slide bar is provided with a spring.

[0010] Optionally, the two ends of the spring are connected to a hand grip and a pressing block, respectively, and a movable block is movably installed at the bottom end of the lead screw.

[0011] Optionally, the bottom of the top plate is equipped with three sets of equally spaced connecting blocks, and each connecting block is provided with a clamping arm on its side wall.

[0012] Optionally, each clamping arm is provided with a hinge shaft at one end near the connecting block, and the clamping arm is movably connected to the connecting block through the hinge shaft.

[0013] Optionally, the side wall of the movable block is provided with three sets of linkage arms at equal intervals. Each linkage arm is provided with a movable shaft at the end near the movable block, and the linkage arm is movably connected to the movable block through the movable shaft.

[0014] Optionally, each of the linkage arms is provided with a connecting shaft at one end near the clamping arm, and the linkage arm is movably connected to the clamping arm through the connecting shaft, and each of the clamping arms is provided with a clamping block on its side wall.

[0015] Optionally, the outside of the hand grip is provided with a placement platform, and the surface of the placement platform is provided with multiple sets of equally spaced limiting holes.

[0016] Optionally, a circuit board is provided at the top of the placement platform, and a capacitor body is mounted at the top of the circuit board.

[0017] Optionally, a locking bolt is provided inside the limiting hole, and the locking bolt is threadedly connected to the limiting hole, and a limiting buckle is provided on the surface of the locking bolt.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the buckle device not only realizes the quick disassembly and replacement of capacitors by clamping the capacitor at the linkage center, which facilitates the adaptation and use of capacitors on circuit boards of different sizes, but also improves the convenience and flexibility of capacitor disassembly and replacement.

[0019] Place the circuit board on the surface of the placement platform. Fit the limit buckle onto the surface of the locking bolt, insert the locking bolt into the limit hole, and tighten the bolt. The locking bolt will move the limit buckle, fixing the circuit board to the surface of the placement platform. Take the hand grip and place the clamping block around the capacitor body. Press the pressing block, which will move the sliding rod. With the limit provided by the hand grip, the pressing block will compress the limit strip. Simultaneously, the pressing block will move the rack, which will be supported by the limit strip. The rack will rotate the threaded sleeve via the toothed ring, which will move the lead screw upwards. The lead screw will move the moving block upwards, which will rotate the linkage arm via the movable shaft. The linkage arm will then move the clamping arm via the connecting shaft at the hinge. The clamping arm is supported by a connecting block for rotation. The clamping arm drives the clamping blocks to rotate synchronously and contact the surface of the capacitor body. The clamping blocks hold and fix the capacitor body in place. Pulling up the handle transmits the upward force to the surface of the clamping blocks through the linkage structure. The clamping blocks then move the capacitor body upward and disengage it from the circuit board. Releasing the pressing block causes it to reset under the elastic action of the spring. This causes the linkage structure to work in the opposite direction, moving the three sets of clamping blocks away from the capacitor body. Afterward, a new capacitor body can be clamped and reinstalled onto the circuit board, thus completing the rapid replacement of the capacitor body. This system enables rapid disassembly and replacement of capacitors by clamping the capacitor at the linkage center, improving the convenience of capacitor disassembly and replacement.

[0020] If the circuit boards are of different sizes, after placing the circuit boards on the placement table, the locking bolts need to be inserted into the limiting holes near the edge of the circuit board according to the position of the circuit board. After inserting and tightening multiple sets of locking bolts one by one, the limiting buckles can fix the circuit boards of different sizes on the surface of the placement table. Then, repeat the above operation to complete the disassembly and replacement of the capacitor body on the circuit boards of different sizes, which facilitates the adaptation and use of capacitors on circuit boards of different sizes and improves the flexibility of adaptation.

[0036] Place the circuit board 2 on the surface of the placement platform 1. Fit the limiting buckle 4 onto the surface of the locking bolt 3.

Take the hand grip 6 and place the clamping block 13 around the capacitor body 5. Press the pressing block 25, which will move the sliding rod 23. Under the limiting action of the hand grip 6, the pressing block... 25 presses against the limiting strip 21, while the pressing block 25 drives the rack 18 to move. The limiting strip 21 provides sliding support for the rack 18. Under the mutual meshing of the rack 18 and the toothed ring 20, and with the movable support of the sleeve 24, the rack 18 drives the threaded sleeve 19 to rotate through the toothed ring 20. With the threaded connection between the threaded sleeve 19 and the lead screw 7, the threaded sleeve 19 drives the lead screw 7 to move upward. The lead screw 7 drives the moving block 16 to move upward. The moving block 16 moves upward through the movable shaft 1. 5 drives the linkage arm 14 to rotate, and the linkage arm 14 drives the clamping arm 12 to rotate around the hinge shaft 10 via the connecting shaft 11. The connecting block 9 provides support for the clamping arm 12. The clamping arm 12 drives the clamping block 13 to rotate synchronously and contact the surface of the capacitor body 5. The clamping block 13 clamps and fixes the capacitor body 5. Pulling up the handle 6, the upward force is transmitted to the surface of the clamping block 13 through the linkage structure, and the clamping block 13 drives the capacitor body 5 to move upward and disengage from the circuit board 2. Releasing the pressing block 25, under the elastic cooperation of the spring 22, the spring 22 drives the pressing block 25 to reset, thereby driving the above linkage structure to work in the opposite direction, so that the three sets of clamping blocks 13 move away from the capacitor body 5. Then, the new capacitor body 5 can be clamped and reinstalled on the circuit board 2 to complete the quick replacement of the capacitor body 5.

After inserting and tightening multiple sets of locking bolts 3 one by one, the limiting buckle 4 can fix the circuit board 2 of different sizes on the surface of the placement platform 1. Then repeat the above operation to complete the disassembly and replacement of the capacitor body 5 on the circuit board 2 of different sizes, which facilitates the adaptation and use of capacitors on circuit boards of different sizes and improves the flexibility of adaptation.

[0042] The working principle of the technical solution provided by this utility model is as follows: The circuit board 2 is placed on the surface of the placement platform 1. The limiting buckle 4 is fitted onto the surface of the locking bolt 3. The locking bolt 3 is inserted into the limiting hole 17 and tightened. The locking bolt 3 drives the limiting buckle 4 to move and fix the circuit board 2 on the surface of the placement platform 1.

Block 25 drives the rack 18 to move, and the limiting strip 21 provides sliding support for the rack 18. Under the mutual meshing of the rack 18 and the toothed ring 20, and under the movable support of the sleeve 24, the rack 18 drives the threaded sleeve 19 to rotate through the toothed ring 20. With the threaded connection between the threaded sleeve 19 and the lead screw 7, the threaded sleeve 19 drives the lead screw 7 to move upward. The lead screw 7 drives the moving block 16 to move upward. The moving block 16 drives the linkage arm 14 to rotate through the movable shaft 15. The linkage arm 14 drives the clamping arm 12 to rotate around the hinge shaft 10 through the connecting shaft 11. The connecting block 9 provides support for the clamping arm 12. Provided with support, the clamping arm 12 drives the clamping block 13 to rotate synchronously and contact the surface of the capacitor body 5. The clamping block 13 clamps and fixes the capacitor body 5. Pulling up the handle 6, the upward force is transmitted to the surface of the clamping block 13 through the linkage structure, and the clamping block 13 drives the capacitor body 5 to move upward and disengage from the circuit board 2. Releasing the pressing block 25, under the elastic cooperation of the spring 22, the spring 22 drives the pressing block 25 to reset, thereby driving the above linkage structure to work in the opposite direction, so that the three sets of clamping blocks 13 move away from the capacitor body 5. Then, a new capacitor body 5 is clamped and reinstalled. Simply place the capacitor body 5 onto the circuit board 2 to complete the quick replacement of the capacitor body 5. If the size of the circuit board 2 is different, after placing the circuit board 2 on the placement platform 1, the locking bolt 3 needs to be inserted into the limiting hole 17 near the edge of the circuit board 2 according to the position of the circuit board 2. After inserting and tightening multiple sets of locking bolts 3 one by one, the limiting buckle 4 can fix the circuit board 2 of different sizes on the surface of the placement platform 1. Then repeat the above operation to complete the disassembly and replacement of the capacitor body 5 on the circuit board 2 of different sizes.
