Description

Technical Field

[0001] This invention relates to the field of electronic component technology, and more particularly to aluminum capacitor cases that facilitate plug-in installation. Background Technology

[0002] A capacitor works by storing electrical energy through the storage of charge on its electrodes. It is typically used in conjunction with an inductor to form an LC resonant circuit. The principle behind capacitor operation is that charges move under the influence of an electric field. When a dielectric material is placed between conductors, it impedes the movement of charges, causing them to accumulate on the conductors, thus storing the charge. Capacitors are among the most widely used electronic components in electronic devices, and are therefore extensively applied in DC blocking, coupling, bypassing, filtering, tuning circuits, energy conversion, and control circuits.

[0003] When using existing capacitor aluminum shells, the aluminum shell and sealing cap are generally connected by chemical adhesive, which makes the connection difficult to disassemble. Forcible disassembly can damage the aluminum shell, making later maintenance and repair inconvenient. Moreover, the capacitor needs to be compatible with various circuit connections, and the terminal connection structure is usually complicated, making it difficult to replace the terminals according to the specific connection structure, which reduces its practicality. In addition, during the insertion process, the positive and negative leads are prone to bending and breakage under external force, affecting the stability of its use. Summary of the Invention

[0004] This disclosure relates to a capacitor aluminum shell that is easy to plug in and install. By manually pressing two elastic push tabs simultaneously and rotating the rotating plate in the opposite direction to disengage the positioning block from the limiting sleeve, the removal of the sealing cap and the aluminum shell is completed. Because the installation and removal of the sealing cap is flexible and quick, the integrity of the aluminum shell is effectively guaranteed, which facilitates later maintenance and repair.

The elastic push pieces are slidably connected to the guide grooves through the guide blocks.

[0009] In at least some embodiments, the sealant cap has a first through hole at its center, and two spline holes are provided on the sealant cap, which are symmetrically distributed, and the terminals correspond to the positions of the spline holes.

[0010] In at least some embodiments, an adjusting column is provided at the middle position of the rotating plate, and the rotating plate is rotatably connected to the first through hole through the adjusting column. Connecting grooves are provided at both ends of the rotating plate, and limit blocks are fixedly installed in the connecting grooves. Adjusting frames are provided at both ends of the rotating plate, and the adjusting frames are set in the connecting grooves. The adjusting frames have a rectangular frame structure, and the adjusting frames are slidably connected to the connecting grooves through the limit blocks.

[0011] In at least some embodiments, one end of the adjustment frame is provided with a positioning block, one side edge of the positioning block is chamfered, the positioning block is provided with two limiting slide rods, and the two limiting slide rods are distributed symmetrically. A first compression spring is fitted on the limiting slide rod, the limiting slide rod is slidably inserted into the end of the rotating plate, and the first compression spring is supported between the rotating plate and the positioning block.

[0012] In at least some embodiments, the terminal has a spline post at the bottom, and the terminal is slidably connected to the spline hole of the sealing cap through the spline post. The bottom end of the spline post has a mating sleeve, and the bottom end of the spline post has two elastic buckles, which are located on both sides of the mating sleeve and are distributed symmetrically.

[0013] In at least some embodiments, the support plate is provided with two connecting bolts, which are symmetrically distributed and fixedly connected to the sealing cap. The support plate has a second through hole at its center, and the rotating plate is rotatably connected to the second through hole through an adjusting column.

[0015] This invention provides a capacitor aluminum shell that is easy to plug in and install, and has the following beneficial effects: In this invention, when the sealing cap is connected to the aluminum shell, the limiting sleeve slides along the limiting groove, aligning the limiting sleeve with the positioning through groove. Simultaneously, by manually rotating the adjusting column, the rotating plate drives the two adjusting frames to rotate, allowing the positioning block to slide along the inner wall of the connecting sleeve, inserting the positioning block into the limiting sleeve. The elasticity of the first compression spring ensures a stable connection between the sealing cap and the aluminum shell. During disassembly, by manually pressing the two elastic push plates simultaneously and rotating the rotating plate in the opposite direction, the positioning block disengages from the limiting sleeve, thus completing the removal of the sealing cap and the aluminum shell. Because the sealing cap installation and removal process is flexible and quick, it effectively ensures the integrity of the aluminum shell and facilitates subsequent maintenance and repair.

[0016] Furthermore, by setting up the terminal and support plate, the two elastic clips of the terminal can be manually pinched in opposite directions to disengage the elastic clips from the rectangular slot of the connecting slot. Then, the terminal is pulled upwards, causing the spline column to slide upwards along the spline hole, so that the terminal can be quickly removed from the sealing cap. Since the entire disassembly process can be easily removed without tools, the efficiency of the terminal's installation and removal is improved. In addition, the terminal can be replaced according to different plug-in structures, which greatly improves its practicality.

[0017] In addition, during the terminal insertion process, the elastic support plate can be supported by the rebound effect of the elastic support plate. The limit plug and the limit through slot are slidably inserted, and the elasticity of the second compression spring can be used to buffer the terminal insertion process, thereby avoiding bending and breakage of the positive and negative leads and effectively ensuring the stability of the capacitor.

The rotating plate 3 has adjusting frames 304 at both ends, and the adjusting frames 304 are set in the connecting grooves 302. The adjusting frames 304 have a rectangular frame structure, and the adjusting frames 304 are slidably connected to the connecting grooves 302 through the limit blocks 303.

In this invention, when the sealing cap 2 is connected to the aluminum shell 1, the limiting sleeve 201 slides along the limiting slide groove 103, connecting the limiting sleeve 201 with the positioning... Corresponding to slot 104, by manually rotating the adjusting column 301, the rotating plate 3 drives the two adjusting brackets 304 to rotate, and the positioning block 3041 can slide along the inner wall of the connecting sleeve 102, so that the positioning block 3041 is inserted into the limiting sleeve 201. The elasticity of the first compression spring 3044 ensures the stable connection between the sealing cap 2 and the aluminum shell 1. During the disassembly process, by manually pressing the two elastic push plates 202 at the same time and rotating the rotating plate 3 in the opposite direction, the positioning block 3041 is disengaged from the limiting sleeve 201, thereby completing the removal of the sealing cap 2 and the aluminum shell 1.

[0025] In this embodiment of the disclosure, such as Figure 7 As shown, the sealant cap 2 has a first through hole 205 at its center, and two spline holes 206 are provided on the sealant cap 2. The two spline holes 206 are distributed symmetrically, and the terminal 4 corresponds to the position of the spline hole 206. The bottom of the terminal 4 is provided with a spline post 401, and the terminal 4 is slidably connected to the spline hole 206 of the sealing cap 2 through the spline post 401. The bottom end of the spline post 401 is provided with a mating sleeve 402, and the bottom end of the spline post 401 is provided with two elastic buckles 403, and the two elastic buckles 403 are located on both sides of the mating sleeve 402, and the two elastic buckles 403 are distributed symmetrically.

The support plate 5 has two connecting slots 503, and the terminal 4 is positioned corresponding to the connecting slot 503. The elastic buckle 403 is engaged with the connecting slot 503. By manually squeezing the two elastic buckles 403 of the terminal 4 in opposite directions, the elastic buckle 403 is disengaged from the rectangular slot of the connecting slot 503. Then, the terminal 4 is pulled upward, causing the spline column 401 to slide upward along the spline hole 206, so that the terminal 4 can be quickly removed from the sealing cap 2.

[0026] Example 2, based on Example 1, such as Figure 8As shown, a positive electrode guide pin 1061 and a negative electrode guide pin 1062 are fixedly inserted through the sealing rubber plate 106, and the positive electrode guide pin 1061 and the negative electrode guide pin 1062 are distributed in a vertical parallel manner.

The limiting rod 504 slides into the limiting through groove 602, and the elasticity of the second compression spring 603 can buffer the insertion process of the terminal 4, thereby preventing the positive electrode needle 1061 and the negative electrode needle 1062 from bending and breaking.

[0027] The working principle of this embodiment is as follows: During installation and use, the limiting sleeve 201 slides along the limiting slide groove 103, aligning the limiting sleeve 201 with the positioning through groove 104. Simultaneously, by manually rotating the adjusting column 301, the rotating plate 3 drives the two adjusting frames 304 to rotate, allowing the positioning block 3041 to slide along the inner wall of the connecting sleeve 102, so that the positioning block 3041 is inserted into the limiting sleeve 201.

Then, the terminal 4 is pulled upward, so that the spline post 401 slides upward along the spline hole 206, thereby allowing the terminal 4 to be quickly removed from the sealing cap 2. During the insertion of terminal 4, the elastic support plate 601 can be used to support the support plate 5. The limiting rod 504 slides into the limiting through slot 602. At the same time, the elasticity of the second compression spring 603 can buffer the insertion process of terminal 4, thereby preventing the positive electrode pin 1061 and the negative electrode pin 1062 from bending and breaking.
