[0002] Aluminum electrolytic capacitors, as key passive components in electronic devices, play an indispensable role in various circuits due to their unique structure and performance. In some industrial fields, aluminum electrolytic capacitors, because of their large capacitance, can be used in critical processes such as energy storage and power factor correction, meeting the needs for energy storage and conversion.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: During the operation of aluminum electrolytic capacitors, the head is often exposed to the outside. When subjected to continuous external pressure, the capacitor body may deform. This deformation will cause damage to the internal structure, and the electrode pins connected at the lower end may become loose, which will lead to abnormal internal circuit connections. Therefore, a pressure-resistant aluminum electrolytic capacitor is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing aluminum electrolytic capacitors, where the capacitor head is often exposed during operation. When subjected to continuous external pressure, the capacitor body may deform, causing damage to the internal structure and loosening of the electrode pins connected to the lower end, leading to abnormal internal circuit connections. Therefore, this invention proposes a pressure-resistant aluminum electrolytic capacitor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure-resistant aluminum electrolytic capacitor, comprising a capacitor body, two electrode pins mounted on the lower end of the capacitor body, a protective shell slidably connected to the outer side of the capacitor body, a baffle threadedly connected to the inner wall of the protective shell, two circular holes at one end of the baffle, the size of the circular holes being adapted to the size of the pins, four circular chambers fixedly connected to the inner wall of the protective shell, springs fixedly connected to the inner wall of the circular chambers, a circular rod fixedly connected to the other end of the springs, the circular rods slidably connected to the inner wall of the circular chambers, and an arc-shaped plate fixedly connected to the end of the circular rod away from the springs, the arc-shaped plate being slidably connected to the outer side of the capacitor body.

[0006] The effect achieved by the above components is as follows: the capacitor body is fixed inside the protective shell by the threaded connection of the baffle to the inner wall of the protective shell, and an arc-shaped plate is provided on the inner wall of the protective shell and slidably connected to the outer side of the capacitor body. The arc-shaped plate is supported by a spring and a round rod structure. When subjected to external force, the spring can play a buffering role, which effectively enhances the capacitor's pressure resistance and improves its stability and service life under complex working conditions.

[0007] Preferably, an arc-shaped pad is fixedly connected to the surface of the arc-shaped plate, and the arc-shaped pad is made of rubber.

[0008] The effects achieved by the above components are as follows: rubber has good elasticity and cushioning properties, which can further enhance the cushioning effect when the capacitor is subjected to external impact, reducing collision damage to the capacitor body; at the same time, the anti-slip properties of rubber can make the capacitor body more stable in the protective shell, preventing its performance and service life from being affected by shaking.

[0009] Preferably, the surface of the baffle has two threaded grooves, and the inner walls of the two threaded grooves of the baffle are threaded with protective sleeves, the size of which is larger than the size of the electrode pins.

[0010] The effects achieved by the above components are as follows: the protective sleeve can protect the electrode pins and prevent them from being damaged by friction or contact; at the same time, the protective sleeve can prevent the electrode pins from being contaminated with impurities to a certain extent, thus ensuring the conductivity of the electrode pins.

[0011] Preferably, one end of the baffle is fixedly connected to a round shaft, and the round shaft has a plurality of anti-slip grooves on its arc surface.

[0012] The effect achieved by the above components is that users can more easily rotate the baffle by turning the round shaft. The anti-slip grooves on the surface of the round shaft can effectively increase the friction between the fingers and the round shaft, making the operation process more convenient and smooth, and improving the ease of operation.

[0013] Preferably, a plurality of heat dissipation fins are fixedly connected to the arc surface of the protective shell, and the plurality of heat dissipation fins are evenly distributed on the arc surface of the protective shell.

[0014] The effect achieved by the above components is that the heat dissipation fins evenly distributed on the arc surface of the protective shell can greatly increase the heat dissipation area of ​​the capacitor body, effectively reduce the temperature of the capacitor body, avoid performance degradation or damage due to overheating, and thus significantly improve the working stability and service life of the capacitor body.

[0015] Preferably, the arc surface of the protective shell is coated with a layer of polytetrafluoroethylene modified material.

[0016] The effects achieved by the above components are as follows: the polytetrafluoroethylene modified material coated on the arc surface of the protective shell has the functions of waterproofing, moisture-proofing and corrosion resistance, which can effectively resist the erosion of the protective shell by external factors. At the same time, the smooth surface of the polytetrafluoroethylene material can also reduce the adhesion of dust, debris and other impurities on the surface of the protective shell.

[0017] Preferably, the bottom surface of the protective shell is provided with a slot, the size of which is adapted to the size of the capacitor body.

[0018] The aforementioned components achieve the following effects: the slot provides precise positioning for the capacitor body, allowing it to be quickly and securely embedded during installation. Simultaneously, it enhances the stability of the capacitor body within the protective casing, preventing it from shaking and effectively reducing issues such as loose connections and performance degradation caused by shaking.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, the capacitor body is fixed inside the protective shell by a baffle threaded into the inner wall of the protective shell. An arc-shaped plate is provided on the inner wall of the protective shell and slidably connected to the outer side of the capacitor body. The arc-shaped plate is supported by a spring and a round rod structure. When subjected to external force, the spring can play a buffering role, which effectively enhances the capacitor's pressure resistance and improves its stability and service life under complex working conditions.

[0026] Reference Figures 1-4As shown, this utility model provides a technical solution: a pressure-resistant aluminum electrolytic capacitor, including a capacitor body 1, with two electrode pins 2 installed at the lower end of the capacitor body 1, a protective shell 3 slidably connected to the outer side of the capacitor body 1, a baffle 4 threadedly connected to the inner wall of the protective shell 3, two circular holes 9 opened at one end of the baffle 4, the size of the circular holes 9 being adapted to the size of the pins, four circular chambers 5 fixedly connected to the inner wall of the protective shell 3, springs 6 fixedly connected to the inner wall of the circular chambers 5, and a circular rod 7 fixedly connected to the other end of the springs 6, the circular rod 7 being slidably connected to the inner wall of the circular chambers 5, and an arc-shaped plate 8 fixedly connected to the end of the circular rod 7 away from the springs 6, the arc-shaped plate 8 being slidably connected to the outer side of the capacitor body 1, the capacitor body 1 being fixed inside the protective shell 3 by the baffle 4 threadedly connected to the inner wall of the protective shell 3, and the arc-shaped plate 8 being provided on the inner wall of the protective shell 3 and slidably connected to the outer side of the capacitor body 1, and the arc-shaped plate 8 being slidably connected to the outer side of the capacitor body 1. The curved plate 8 is supported by a spring 6 and a round rod 7. When subjected to external force, the spring 6 can act as a buffer, effectively enhancing the capacitor's resistance to pressure and improving its stability and service life under complex working conditions. The surface of the curved plate 8 is fixedly connected to a curved pad 10, which is made of rubber. Rubber has good elasticity and buffering performance, which can further enhance the buffering effect when the capacitor is subjected to external impact, reducing collision damage to the capacitor body 1. At the same time, the anti-slip properties of rubber can make the capacitor body 1 more stable in the protective shell 3, preventing the performance and service life from being affected by shaking. The surface of the baffle 4 has two threaded grooves, and the inner walls of the two baffle 4 threaded grooves are threaded with protective sleeves 11. The size of the protective sleeves 11 is larger than the size of the electrode pins 2. The protective sleeves 11 can protect the electrode pins 2 and prevent the electrode pins 2 from being damaged by friction and contact.Meanwhile, the protective sleeve 11 can prevent impurities from contaminating the electrode pins 2 to a certain extent, ensuring the conductivity of the electrode pins 2. One end of the baffle 4 is fixedly connected to a round shaft 12. The arc surface of the round shaft 12 is provided with several anti-slip grooves 13. Users can more conveniently rotate the baffle 4 by rotating the round shaft 12. The anti-slip grooves 13 on the surface of the round shaft 12 can effectively increase the friction between the fingers and the round shaft 12, making the operation process more convenient and smooth, and improving the ease of operation. Several heat dissipation fins 14 are fixedly connected to the arc surface of the protective shell 3. The heat dissipation fins 14 are evenly distributed on the arc surface of the protective shell 3. The heat dissipation fins 14 evenly distributed on the arc surface of the protective shell 3 can greatly increase the heat dissipation area of ​​the capacitor body 1, effectively reduce the temperature of the capacitor body 1, avoid performance degradation or damage due to overheating, and thus significantly improve performance. To enhance the working stability and service life of the capacitor body 1, the arc surface of the protective shell 3 is coated with a layer of modified polytetrafluoroethylene (PTFE) material. This PTFE material provides waterproofing, moisture resistance, and corrosion resistance, effectively protecting the protective shell 3 from external erosion. Furthermore, the smooth surface of the PTFE material reduces the adhesion of dust and debris to the protective shell 3. A slot 15 is provided on the bottom surface of the protective shell 3, its size matching the size of the capacitor body 1. The slot 15 provides precise positioning for the capacitor body 1, allowing it to be quickly and securely inserted into the slot during installation. This also enhances the stability of the capacitor body 1 within the protective shell 3, preventing it from shaking and effectively reducing the risk of loose connections and performance degradation due to shaking.

[0027] The working principle is as follows: First, the capacitor body 1 is quickly and securely embedded in the protective shell 3 through a slot 15 that matches the size of the capacitor body 1. This precise positioning enhances its stability within the protective shell 3, preventing loosening of internal connections due to shaking. During installation, the user rotates the round shaft 12 with anti-slip grooves 13 at one end of the baffle 4, using the increased friction to easily screw the baffle 4. The capacitor body 1 is then fixed inside the protective shell 3 via the threaded connection of the baffle 4 to the inner wall of the protective shell 3. When subjected to external force, the arc-shaped plate 8, which slides on the outside of the capacitor body 1, transmits the force to the structure supported by the spring 6 and the round rod 7. The spring 6 acts as a buffer, and the rubber arc-shaped pad 10 further enhances the buffering effect, reducing collision damage and stabilizing the capacitor body 1 with its anti-slip properties. The electrode leads 2 pass through the round holes 9 on the baffle 4 and are protected by a larger protective sleeve 11 to prevent damage from friction and contact with impurities, ensuring conductivity. During operation, the heat dissipation fins 14 evenly distributed on the arc surface of the protective shell 3 increase the heat dissipation area, reduce the temperature of the capacitor body 1, and avoid overheating that could affect performance. The coated polytetrafluoroethylene modified material provides waterproof, moisture-proof, and corrosion-resistant functions, resisting external erosion. Its smooth surface reduces the adhesion of dust and debris, ensuring the capacitor operates stably under complex working conditions and extending its service life.
