The multi-layer structure of the sealing component 5 further enhances the sealing performance of the capacitor and protects the internal components from the external environment.

[0046] Furthermore, a rotating support 10 is provided at the center of the sealing base 9, and a thread is provided at the center of the rotating support 10. Four threaded holes three 13 are provided on the sealing base 9 centered on the rotating support 10.

This capacitor can be compatible with various sealing structures, adapt to different application scenarios, increase market competitiveness. By using the above-optimized sealing structure, the capacitor has better heat dissipation, sealing and shock resistance capabilities, improving the overall performance and stability.

[0052] Working principle: When in use, by placing the sealing base 9 into the capacitor housing 1 and abutting it against the bolt seat 4, several groups of bolt seats 4 play a supporting role for the sealing base 9. At this time, as shown in, the sealing base 9, the connecting plate 11 and the locking bracket 12 are in a "Z" - shaped structure. Then, by pushing the locking bracket 12 downward and through the settings of the first rotating shaft 16 and the second rotating shaft 18, the connecting plate 11 moves in a direction parallel to the sealing base 9 until the four groups of pads 21 abut against the top of the sealing base 9. Subsequently, a gap for accommodating the connecting plate 11 is left between the sealing base 9 and the locking bracket 12 to prevent the connecting plate 11 from being damaged. At this time, a set of screws can be first screwed into the first threaded hole 20, pass through the first avoiding groove 17 and the second through - hole 15, and then be screwed into the rotating support 10 for preliminary positioning. Subsequently, four groups of screws are respectively screwed into the third threaded hole 13 through the first threaded hole 20 on the pads 21, thereby completing the fixation of the sealing assembly 5. Among them, the setting of several groups of second avoiding grooves 22 can not only reduce the mass of the locking bracket 12, but also provide an extension space for the pin 6. And through the rotational setting of the connecting member 14 and the rotating support 10, the angle of the locking bracket 12 can be adjusted to facilitate the alignment of the second avoiding groove 22 with the pin 6. Figure 5 As shown in, the sealing base 9, the connecting plate 11 and the locking bracket 12 are in a "Z" - shaped structure. Then, by pushing the locking bracket 12 downward and through the settings of the first rotating shaft 16 and the second rotating shaft 18, the connecting plate 11 moves in a direction parallel to the sealing base 9 until the four groups of pads 21 abut against the top of the sealing base 9. Subsequently, a gap for accommodating the connecting plate 11 is left between the sealing base 9 and the locking bracket 12 to prevent the connecting plate 11 from being damaged. At this time, a set of screws can be first screwed into the first threaded hole 20, pass through the first avoiding groove 17 and the second through - hole 15, and then be screwed into the rotating support 10 for preliminary positioning. Subsequently, four groups of screws are respectively screwed into the third threaded hole 13 through the first threaded hole 20 on the pads 21, thereby completing the fixation of the sealing assembly 5. Among them, the setting of several groups of second avoiding grooves 22 can not only reduce the mass of the locking bracket 12, but also provide an extension space for the pin 6. And through the rotational setting of the connecting member 14 and the rotating support 10, the angle of the locking bracket 12 can be adjusted to facilitate the alignment of the second avoiding groove 22 with the pin 6.

[0053] When it is necessary to repair or disassemble the capacitor core 3, just unscrew all the bolts. After pulling the locking bracket 12 up, continue to apply force, and then the sealing base 9 can be pulled out of the capacitor housing 1 through the connecting plate 11.
