[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the attached Figure 1 to the attached Figure 5 figure: An aluminum electrolytic capacitor with an efficient packaging structure includes an outer shell 1. A cover body 2 is provided at the top of the outer shell 1. A pin hole is opened at the top of the cover body 2 so that the pins can leak out of the cover body 2.

[0023] An annularly arranged slot 3 is opened on the inner wall of the outer shell 1. The shape of the slot 3 is triangular. A connection and sealing component 4 is provided below the cover body 2. The connection and sealing component 4 includes a ring frame 401 fixedly connected to the bottom surface of the cover body 2. An annular gasket 402 is fixedly connected to the outer surface of the ring frame 401. Annularly arranged through slots 403 are opened on the outer surface of the ring frame 401. A slide bar 404 is arranged inside each through slot 403. An insert block 405 is fixedly connected to one end of each slide bar 404 close to the outer shell 1. The insert block 405 is adapted to the slot 3. When the insert block 405 enters the slot 3, a connection is formed between the cover body 2 and the outer shell 1, and at the same time, the annular gasket 402 seals the top of the outer shell 1.

[0024] A hanging plate 406 is slidably connected to the outer surface of each slide bar 404. The top end of each hanging plate 406 is connected to the bottom surface of the cover body 2. The hanging plate 406 can be used to suspend the slide bar 404, ensuring the stability of the slide bar 404 and enabling the insert block 405 to be aligned with the slot 3.

[0025] A retaining ring 407 is fixedly connected to the outer surface of each sliding rod 404. A spring 408 is sleeved on the outer surface of each sliding rod 404. One end of each group of springs 408 away from each other is respectively connected to one side surface of each group of retaining rings 407 close to each other. One end of each group of springs 408 close to each other is respectively connected to one side surface of each group of hanging plates 406 away from each other. A baffle 409 is fixedly connected to one end of each sliding rod 404 away from the housing 1. By using the elasticity of the spring 408, the retaining ring 407 can be pushed, and the sliding rod 404 will then push the insertion block 405, so that the connection between the insertion block 405 and the slot 3 will be more stable. At the same time, the baffle 409 will limit the moving distance of the sliding rod 404, and it can prevent the sliding rod 404 from separating from the hanging plate 406.

[0026] The connection sealing assembly 4 further includes two groups of stable grooves 410 opened on the bottom surface of the cover body 2. A stable rod 411 is slidably connected to the inner wall of each stable groove 410. The bottom ends of each group of stable rods 411 are respectively connected to one side surface of each group of baffles 409 close to each other. By using the connection between the stable rod 411, the stable groove 410 and the baffle 409, the baffle 409 and the sliding rod 404 can be stabilized, and it can prevent the sliding rod 404 from rotating, thus facilitating the connection between the insertion block 405 and the slot 3.

[0027] An annular support plate 5 is fixedly connected to the inner wall of the housing 1. The upper surface of the annular support plate 5 is in contact with the bottom surface of the annular frame 401. By using the annular support plate 5, not only can the annular frame 401 be supported, but also the bottom of the annular frame 401 can be further sealed, thereby improving the sealing effect.

[0028] An annular sealing block 6 is fixedly connected to the outer surface of the cover body 2. The inner wall of the annular sealing block 6 is in contact with the outer surface of the housing 1. By using the annular sealing block 6, the gap between the cover body 2 and the housing 1 can be sealed, thereby ensuring the sealing effect of the housing 1.

[0029] Working principle: When in use, align the insertion block 405 on the cover body 2 with the slot 3, and at the same time pass the lead on the capacitor through the through hole on the cover body 2. Then press the cover body 2 downward. The housing 1 will squeeze the insertion block 405, and the insertion block 405 will enter the through groove 403. The retaining ring 407 will compress the spring 408. When the insertion block 405 reaches the slot 3, the spring 408 will push the retaining ring 407, and the sliding rod 404 will push the insertion block 405 into the slot 3, thus quickly forming the connection between the cover body 2 and the housing 1. At the same time, the annular gasket 402 will be in close contact with the inside of the housing 1 to seal the housing 1. It is more convenient for the staff to install and ensures the packaging efficiency.
