AI Technical Summary
When subjected to external impact, the electrolytic paper core of existing horn capacitors is prone to shaking or breakage, rendering the capacitor unusable.
An anti-vibration component, including wing plates, clips, and rubber strips, is installed between the outer and inner shells. The deformation of the rubber strips absorbs the impact force, reducing damage to the electrolytic paper core.
This improves the capacitor's vibration resistance, prevents the electrolytic paper core from breaking under external impact, and extends the capacitor's service life.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor technology, specifically to a vibration-resistant horn capacitor. Background Technology
[0002] A horn capacitor, also known as a horn electrolytic capacitor or a foil-type electrolytic capacitor, is a type of power capacitor with a specific shape (resembling a bull's horn) and characteristics.
[0003] The basic principle of a horn capacitor is to utilize its electric field effect to form a high-frequency path within the device, thereby effectively shielding high-frequency noise. The extremely small distance between its electrodes and the dielectric contributes to achieving a highly efficient electric field shielding effect.
[0004] Conventional electrolytic paper cores are directly embedded in aluminum shells. Therefore, when the aluminum shell is subjected to external impact, the electrolytic paper core inside will also shake, which will cause the electrolytic paper core to shift or break inside the aluminum shell. The electrolyte inside the broken electrolytic paper core will also penetrate and corrode the aluminum shell, making the entire capacitor unusable. Utility Model Content

[0025] 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.
[0026] Please see Figure 1-3 An anti-vibration horn capacitor includes a shell 1 and an inner shell 2. An anti-vibration component 3 is disposed between the shell 1 and the inner shell 2 to improve the overall anti-vibration performance of the capacitor. A lower cover 4 is threadedly connected to the bottom of the shell 1. An electrolytic paper core 5 is disposed inside the inner shell 2. The electrolytic paper core 5 can be disassembled or installed by removing the lower cover 4 from the bottom of the shell 1.
[0027] Please see Figure 1-3 The inner shell 2 has a top cover plate 6, and a sealing ring 7 is embedded inside the top cover plate 6. The top of the outer shell 1 is threadedly connected to an upper sealing ring 8. The electrode posts at the top of the electrolytic paper core 5 pass through the sealing ring 7 and extend to the outside of the upper sealing ring 8. The inner diameter of the upper sealing ring 8 is larger than the spacing of the electrode posts at the top of the electrolytic paper core 5. A protrusion 9 is fixedly installed on the top of the upper sealing ring 8. The protrusion 9 can drive the upper sealing ring 8 to move up or down in the outer shell 1; when moving up, the upper sealing ring 8 leaves the outer shell 1, allowing the electrolytic paper core 5 to be disassembled and installed; when moving down, the upper sealing ring 8 presses against the top cover plate 6, thereby preventing the electrolytic paper core 5 from sliding out.
[0028] Please see Figure 3-5 The seismic-resistant component 3 includes a wing plate 31, with a clamp 32 fixedly installed at the tail end of the wing plate 31. The end of the wing plate 31 away from the clamp 32 is fixedly connected to the outer wall of the inner shell 2. Side plates 33 are provided on both sides of the wing plate 31, and the end of the side plate 33 away from the clamp 32 is fixedly connected to the inner wall of the outer shell 1. A rubber strip 36 is fixedly installed on the side of the clamp 32, and the rubber strip 36 is placed between the two side plates 33. Deformation holes 37 are opened inside the rubber strip 36.
[0029] Please see Figure 3-5 Rubber strip 34 is fitted onto the surface of the clip 32, and rubber strip 35 is fitted onto the inner wall of the side plate 33. Rubber strip 34 and rubber strip 35 correspond to each other. When the wing plate 31 is in the side plate 33, rubber strips 34, 35 and 36 will deform, thereby mitigating the impact force.
[0030] Working principle: When in use, first thread the lower cover 4 to the bottom of the outer shell 1, then install the electrolytic paper core 5 in the inner shell 2, then cover the top of the inner shell 2 with the upper cover plate 6, and then thread the upper sealing ring 8 into the top of the outer shell 1. This process realizes the installation of the electrolytic paper core 5, and the reverse process can disassemble the electrolytic paper core 5.
[0031] The outer wall of the inner shell 2 is fixedly installed with a wing plate 31, and the inner wall of the outer shell 1 is fixedly installed with a side plate 33. The wing plate 31 moves between the two side plates 33 through a clamp 32. A rubber strip 34 is provided on one side of the clamp 32, and a rubber strip 36 is provided on the other side of the clamp 32. A rubber strip 35 is provided on the inner wall of the side plate 33. When the outer shell 1 is impacted, the wing plate 31 slides in the side plate 33, and the three rubber strips begin to deform to reduce the impact force. In this way, the electrolytic paper core 5 in the inner shell 2 will not be easily damaged, thereby improving the vibration resistance of the entire capacitor.
[0032] 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.
