[0002] A capacitor is a basic linear electronic component used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and DC isolation circuits.

[0003] For example, CN217182032U discloses a novel solid-state electrolytic capacitor for preventing leakage current, which includes an electrolytic capacitor body, a barrier pad fixedly connected to the lower surface of the electrolytic capacitor body, a fixing plate provided on the lower surface of the electrolytic capacitor body, the upper surface of the fixing plate overlapping the lower surface of the barrier pad, and two connecting blocks fixedly connected to the outer surface of the fixing plate, with fixing blocks fixedly connected to the upper surface of each of the two connecting blocks.

[0004] In the prior art, the sealed casing of a capacitor requires the capacitor's leads to protrude. However, the seal between the leads and the sealed casing is poor, allowing external moisture, dust, and impurities to easily enter the capacitor. This may create a conductive path at the connection between the leads and the internal electrodes, leading to leakage and affecting the capacitor's performance and lifespan. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor sealing between the pins and the sealed shell in the existing technology, which allows external moisture, dust and impurities to easily enter the capacitor and cause leakage. Therefore, this invention proposes a leakage-proof sealed capacitor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leakage-proof sealed capacitor, comprising a capacitor body, a first sealing mechanism installed at the pins of the capacitor body, the first sealing mechanism comprising a first sealing ring and a second sealing ring, one end of the first sealing ring being fixedly connected to one end of the second sealing ring, both the first and second sealing rings being sleeved on the outside of the pins of the capacitor body, the other end of the first sealing ring being fixedly connected to a movable sleeve, a threaded sleeve being rotatably connected to the outside of the movable sleeve, a positioning ring being threadedly connected to the outside of the threaded sleeve, a second sealing mechanism being installed on the outside of the capacitor body, the second sealing mechanism comprising a first sealing shell and a second sealing shell, the pins of the capacitor body passing through one end of the first sealing shell, one end of the positioning ring being fixedly connected to one end of the first sealing shell, and the other end of the second sealing ring being engaged inside the first sealing shell.

[0007] Preferably, both ends of the threaded sleeve are abutted by a sleeve ring, and the inner ring surface of the sleeve ring is fixedly connected to the outer surface of the movable sleeve.

[0008] Preferably, a second mounting collar is fixedly connected to one end of the first sealing shell, a first mounting collar is fixedly connected to one end of the second sealing shell, and a fixing bolt is installed between the first mounting collar and the second mounting collar.

[0009] Preferably, a sealing groove is provided at one end of the first sealing shell, and a third sealing ring is fixedly connected to one end of the second sealing shell, wherein the outer side of the third sealing ring engages with the inner side of the sealing groove.

[0010] Preferably, positioning posts are fixedly connected inside the first sealing shell and the second sealing shell, with one end of each positioning post abutting against both ends of the capacitor body.

[0011] Preferably, a protective sleeve is fitted around the outside of the capacitor body.

[0012] Preferably, the outer ring surface of the protective sleeve is fixedly connected to an abutment post, and one end of the abutment post is fixedly connected to a sealing sleeve. The outer ring surface of the sealing sleeve abuts against the inner ring surface of the second sealing shell and the inner ring surface of the first sealing shell, respectively.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the second sealing ring and the sleeve ring are placed outside the pins of the capacitor body. The threaded sleeve is rotated and moves outside the positioning ring. The moving sleeve drives the sleeve ring and the second sealing ring to move closer to the first sealing shell, thereby improving the sealing between the first sealing shell and the pins of the capacitor body, preventing external moisture, dust and impurities from entering the interior, and reducing the occurrence of leakage.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a leakage-proof sealed capacitor, including a capacitor body 1. A first sealing mechanism 2 is installed at the pins of the capacitor body 1. The first sealing mechanism 2 includes a first sealing ring 22 and a second sealing ring 26. One end of the first sealing ring 22 is fixedly connected to one end of the second sealing ring 26. Both the first sealing ring 22 and the second sealing ring 26 are sleeved on the outside of the pins of the capacitor body 1. A movable sleeve 24 is fixedly connected to the other end of the first sealing ring 22. A threaded sleeve 23 is rotatably connected to the outside of the movable sleeve 24. A positioning ring 21 is threadedly connected to the outside of the threaded sleeve 23. A second sealing mechanism 3 is installed on the outside of the capacitor body 1. The second sealing mechanism 3 includes a first sealing shell 31 and a second sealing shell 36. The pins of the capacitor body 1 pass through one end of the first sealing shell 31. One end of the positioning ring 21 is fixedly connected to one end of the first sealing shell 31. The other end of the second sealing ring 26 is engaged inside the first sealing shell 31. Both ends of the threaded sleeve 23 abut against a sleeve ring 25. The inner ring surface of the sleeve ring 25 is fixedly connected to the outer surface of the movable sleeve 24.

[0024] After the capacitor body 1 is installed inside the second sealing mechanism 3, the two leads of the capacitor body 1 protrude from one end of the first sealing shell 31. The second sealing ring 26 and the sleeve ring 25 are then fitted over the leads of the capacitor body 1. The position of the second sealing ring 26 is moved towards the first sealing shell 31, so that one end of the threaded sleeve 23 contacts the positioning ring 21. Then, the threaded sleeve 23 is rotated. The threaded sleeve 23 has threads on its outside. During the rotation of the threaded sleeve 23, the threaded sleeve 23 moves outside the positioning ring 21. 23 rotates outside the movable sleeve 24. Sleeve rings 25 are provided at both ends of the threaded sleeve 23 to position the rotation of the threaded sleeve 23. During rotation, the movable sleeve 24 drives the sleeve rings 25 and the second sealing ring 26 closer to the first sealing shell 31. The second sealing ring 26 engages with the interior of the first sealing shell 31, thereby improving the sealing between the first sealing shell 31 and the leads of the capacitor body 1, preventing external moisture, dust, and impurities from entering the interior, and reducing leakage.

[0025] Example 2: Figure 1 - Figure 4 As shown, a second mounting collar 38 is fixedly connected to one end of the first sealing shell 31, and a first mounting collar 35 is fixedly connected to one end of the second sealing shell 36. A fixing bolt 34 is installed between the first mounting collar 35 and the second mounting collar 38. A sealing groove 39 is opened at one end of the first sealing shell 31, and a third sealing ring 37 is fixedly connected to one end of the second sealing shell 36. The outside of the third sealing ring 37 engages with the inside of the sealing groove 39. Positioning pins 32 are fixedly connected to the inside of both the first sealing shell 31 and the second sealing shell 36. One end of the positioning pin 32 abuts against both ends of the capacitor body 1. A protective sleeve 310 is sleeved on the outside of the capacitor body 1. An abutting pin 311 is fixedly connected to the outer ring surface of the protective sleeve 310. A sealing sleeve 33 is fixedly connected to one end of the abutting pin 311. The outer ring surface of the sealing sleeve 33 abuts against the inner ring surface of the second sealing shell 36 and the inner ring surface of the first sealing shell 31.

[0026] The overall effect of this embodiment is that the protective sleeve 310 is placed over the outside of the capacitor body 1, the leads of the capacitor body 1 pass through the first sealing shell 31, and the second mounting ring 38 at one end of the first sealing shell 31 and the first mounting ring 35 at one end of the second sealing shell 36 are fixedly installed by the fixing bolt 34. The third sealing ring 37 is engaged inside the sealing groove 39, which can seal the connection between the second sealing shell 36 and the first sealing shell 31. At this time, the positioning pins 32 abut against both ends of the capacitor body 1, and the sealing sleeve 33 abuts against the inside of the first sealing shell 31 and the second sealing shell 36, thereby positioning the capacitor body 1 inside the first sealing shell 31 and the second sealing shell 36, preventing the capacitor body 1 from shaking, and being able to withstand a certain degree of physical impact, thus protecting the capacitor body 1 and ensuring the internal sealing.

[0027] The method of use and working principle of this device are as follows: The protective sleeve 310 is placed on the outside of the capacitor body 1. The second mounting ring 38 and the first mounting ring 35 are fixedly installed by the fixing bolt 34. The third sealing ring 37 is engaged inside the sealing groove 39 to seal the connection between the second sealing shell 36 and the first sealing shell 31. The positioning pins 32 are respectively abutted against the two ends of the capacitor body 1. The sealing sleeve 33 abuts against the inside of the first sealing shell 31 and the second sealing shell 36, positioning the capacitor body 1 inside the first sealing shell 31 and the second sealing shell 36. The two pins of the capacitor body 1 pass out from one end of the first sealing shell 31. The second sealing ring 26 and the sleeve ring 25 are placed on the outside of the pins of the capacitor body 1. The threaded sleeve 23 is rotated. The threaded sleeve 23 has threads on its outside. During the rotation of the threaded sleeve 23, the threaded sleeve 23 moves outside the positioning ring 21, so that the second sealing ring 26 is engaged inside the first sealing shell 31 during the rotation of the threaded sleeve 23.
