Technical Field

The utility model relates to the technical field of capacitors, concretely relates to solid-state polymer aluminum electrolytic capacitor.

Background

In the manufacturing process of the solid aluminum electrolytic capacitor, plastic packaging is needed, but the sealing performance of the current solid aluminum electrolytic capacitor is poor, and in the case that the solid aluminum electrolytic capacitor is used in an environment with high humidity, moisture easily enters the core of the laminated solid aluminum electrolytic capacitor through a plastic packaging material, so that the product fails.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a solid polymer aluminum electrolytic capacitor aiming at the defects and shortcomings of the prior art.

In order to achieve the above object, the utility model adopts the following technical scheme: the solid polymer aluminum electrolytic capacitor has the innovation points that: including metal casing, set up sealed lid on the metal casing, set up multilayer core in the metal casing, and electrically connected has anodal guide pin and negative pole guide pin on the core at top, sealed lid is worn out to anodal guide pin and negative pole guide pin, the top of core sets up the apron, fill silica gel between apron, metal casing and the core, the top of apron sets up the baffle of wave structure, it fills up to cover the one deck on the baffle is sealed, sealed the pad is arranged along the baffle shape, fill silica gel between sealed pad and the sealed lid.

Further, the below of sealed lid sets up a plurality of sand grips, in the recess of sand grip embedding baffle, extrude silica gel.

Furthermore, two through holes for the penetration of the anode guide pin and the cathode guide pin are formed in the sealing cover, and a rubber pad with a hole in the middle is arranged in each through hole.

Further, insulating pads are arranged between the positive end of the core and the cover plate and between the negative end of the core and the cover plate.

After the structure is adopted, the utility model discloses beneficial effect does:

the utility model discloses a set up inside silica gel, apron, baffle and the sealed pad can effectually prevent that steam from getting into the core package, improve the moisture resistance of condenser, ensure condenser service quality.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Description of reference numerals:

the device comprises a metal shell 1, a sealing cover 2, a core 3, a positive electrode guide pin 4, a negative electrode guide pin 5, a cover plate 6, silica gel 7, a partition plate 8, a sealing gasket 9, a convex strip 10, a rubber gasket 11 and an insulating gasket 12.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Referring to fig. 1, a solid polymer aluminum electrolytic capacitor comprises a metal shell 1, a sealing cover 2 is arranged on the metal shell 1, a plurality of layers of cores 3 are arranged in the metal shell 1, a core at the top is electrically connected with an anode guide pin 4 and a cathode guide pin 5, the anode guide pin 4 and the cathode guide pin 5 penetrate out of the sealing cover 2, a cover plate 6 is arranged at the top of the core 3, the cover plate 6 is filled with silica gel 7 between the metal shell 1 and the core 3, a partition plate 8 with a wave-shaped structure is arranged above the cover plate 6, a layer of sealing gasket 9 is covered on the partition plate 8, the sealing gasket 9 is arranged along the shape of the partition plate 8, and the silica gel 7 is filled between the sealing gasket 9 and the sealing cover 2. Specifically, adopt metal casing 1 and sealed lid 2, can improve the leakproofness, the rethread is filled the silica gel and is set up apron 6, baffle 8 and sealed pad 9 and can improve the leakproofness, can effectually prevent that steam from getting into inside the core package, improves the moisture resistance of condenser, ensures condenser service quality.

In this embodiment, the below of sealed lid 2 sets up a plurality of sand grips 10, and in the recess of sand grip 10 embedding baffle, extrude silica gel, can increase the area of contact of silica gel and sand grip 10 to do benefit to fixedly and sealed.

In this embodiment, the sealing cover 2 is provided with two through holes for the penetration of the anode guide pin and the cathode guide pin, and the through holes are provided with rubber pads 11 with holes in the middle. Rubber pad 11 can prevent that anodal guide pin 3 and negative pole guide pin 4 from switching on with sealed lid 2, damage the condenser, and the gap between guide pin and sealed 2 through-holes of lid can be filled to rubber pad 11 simultaneously, stops steam from the through-hole entering condenser.

In this embodiment, insulating pads 12 are disposed between the positive terminal of the wick 3 and the cover plate and between the negative terminal of the wick 3 and the cover plate.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
