[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4A horn-shaped aluminum electrolytic capacitor includes a shell 1. The top and bottom of the shell 1 are provided with internal threaded grooves. A connecting plate 2 is fixedly installed on the inner wall of the shell 1. An inner shell 3 is fixedly installed at the other end of the connecting plate 2. The height of the inner shell 3 is less than the height of the shell 1. An electrolytic paper core 4 is provided inside the inner shell 3. An electrode post 5 is fixedly installed on the top of the electrolytic paper core 4. A cavity is formed between the shell 1, the connecting plate 2 and the inner shell 3, which not only isolates the electrolytic paper core 4 but also protects it.

[0023] Please see Figures 1-4 The bottom of the outer shell 1 is threadedly connected to a base support 6. The diameter of the base support 6 is equal to the inner diameter of the outer shell 1. A sealing plate 7 is fixedly installed on the bottom of the base support 6. The diameter of the sealing plate 7 is equal to the outer diameter of the outer shell 1. By twisting the sealing plate 7, the base support 6 can be installed and removed from the bottom of the outer shell 1. The bottom of the base support 6 will press against the bottom of the inner shell 3 to seal the bottom of the inner shell 3.

[0024] Please see Figures 1-4 The inner shell 3 has a pressure plate 8 inside, and a sealing ring 9 is embedded inside the pressure plate 8. The top of the electrode post 5 passes through the sealing ring 9 and extends to the outside of the outer shell 1. A protruding ring 10 is fixedly installed at the bottom of the pressure plate 8, and a pressure pad 11 is provided at the top of the pressure plate 8. When the pressure pad 11 is subjected to force and moves downward, the protruding ring 10 at the bottom of the pressure plate 8 will press against the top of the inner shell 3, which can restrict the electrolytic paper core 4 installed in the inner shell 3 and seal the top of the inner shell 3.

[0025] Please see Figures 1-4 A sealing ring 12 is threadedly connected to the top of the outer casing 1. The inner diameter of the sealing ring 12 is larger than the distance between the two electrode posts 5. A protrusion 13 is fixedly installed on the surface of the sealing ring 12. The sealing ring 12 can be disassembled and installed on the top of the outer casing 1 by means of the protrusion 13.

[0026] Working principle: In use, the electrolytic paper core 4 is installed in the inner shell 3 beforehand, and then the sealing plate 7 and the bottom support 6 are threaded to the bottom of the outer shell 1. The bottom support 6 will seal the bottom of the inner shell 3. Then, the pressure plate 8 is placed on the top of the inner shell 3, where the electrode post 5 is inserted in the sealing ring 9. Then, the sealing ring 12 can be driven by the protrusion 13 to be threaded to the top of the outer shell 1. As the sealing ring 12 rotates and moves down, the pressure pad 11 and the pressure plate 8 seal the top of the inner shell 3.

[0027] The bottom support 6 can be twisted off from the bottom of the outer shell 1 by the sealing plate 7, and the sealing ring 12 can be removed from the top of the outer shell 1 by the protruding strip 13. Then the pressure pad 11 can be removed. The protruding ring 10 at the bottom of the pressure plate 8 no longer presses against the electrolytic paper core 4, so the electrolytic paper core 4 can be pulled out from the inner shell 3, thereby realizing the quick disassembly of the capacitor. Compared with the traditional method of directly cutting the capacitor in half, the disassembly of this application will not damage the electrolytic paper core, reduce electrolyte leakage, and reduce environmental pollution.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
