Abstract
The utility model provides an aluminum-electrolytic capacitor characterized by large ripple resistance and long service life. The aluminum-electrolytic capacitor comprises a positive foil riveted with a positive guide pin, a negative foil riveted with a negative guide pin, and electrolytic papers laid on the positive foil and the negative foil. Lining aluminum foils are also riveted at the negative guide pin riveted on the positive foil and/or the positive guide pin riveted on the negative foil of the aluminum-electrolytic capacitor before being wound, and are riveted under the positive foil and the negative foil. The lining aluminum foils are arranged on the front side of the positive foil and/or the back side of the negative foil, and are jointly riveted on the positive foil and the negative foil, together with the positive guide pin and the negative guide pin. The lining aluminum foils riveted at the positive guide pin and the negative guide pin are in contact with the positive aluminum foil and the negative aluminum foil, thereby increasing a novel current path, improving the ripple current resistant capacity of the product, weakening the point discharge of aluminum burrs in an electric field, improving the reliability of the product, and prolonging the service life of the product.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor.
Background technology
In the existing aluminium electrolytic capacitor production technology, its positive and negative guide pin thorn riveting just, on the attached utmost point aluminium foil, current path does not have shunting, aluminium tongue burr point discharge easily causing capacitor short-circuit punctures under electric field.
Summary of the invention
The purpose of this utility model provides the anti-big ripple of a kind of product, long-life aluminium electrolytic capacitor.
For addressing the above problem, solution of the present utility model is:
A kind of aluminium electrolytic capacitor, comprise that the thorn riveting has the cathode foil of anodal guide pin, the anode foil that the thorn riveting has the negative pole guide pin, and be laid on electrolytic paper on the positive and negative electrode paper tinsel, the anodal guide pin of the thorn riveting place riveting one segment liner aluminium foil that ripostes on thorn riveting negative pole guide pin place and/or the cathode foil on the anode foil of the aluminium electrolytic capacitor before the described coiling.
The riveting of liner aluminium foil thorn is below the positive and negative electrode guide pin.
The liner aluminium foil is located at the front or the back side of positive and negative electrode paper tinsel, and stings riveting on the positive and negative electrode paper tinsel together with the positive and negative electrode guide pin.
Owing to adopt technique scheme, realized the disclosed purpose of this new technique preferably, the liner aluminium foil of thorn riveting at positive and negative guide pin place contacts with the positive and negative electrode aluminium foil, increased new current path, improved the anti-ripple current ability of product, weaken aluminium tongue burr point discharge under electric field, improved reliability of products, prolonged the useful life of product.Through test, it is nearly 50% that the ability of bearing ripple current improves, and prolongs nearly 30% useful life.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As illustrated in fig. 1 and 2, aluminium electrolytic capacitor of the present utility model comprises that the thorn riveting has the cathode foil 2 of anodal guide pin 4, the anode foil 1 that the thorn riveting has negative pole guide pin 5, be laid on the electrolytic paper on the positive and negative electrode paper tinsel, anode foil 1 thorn riveting negative pole guide pin 5 places of the aluminium electrolytic capacitor before reeling and the anodal guide pins of the cathode foil 2 thorn rivetings 4 places riveting one segment liner aluminium foil 3 that ripostes.As shown in Figure 2, this liner aluminium foil 3 is located at the front of positive and negative electrode paper tinsel (2,1), and the 3 thorn rivetings of liner aluminium foil are below positive and negative electrode guide pin (4,5).
As shown in Figure 3, the utility model can also adopt another kind of frame mode promptly: positive and negative electrode paper tinsel 1 back side is located in the 3 thorn rivetings of liner aluminium foil, and is integral together with positive and negative electrode paper tinsel 1 and the 5 thorn rivetings of positive and negative electrode guide pin.
In like manner, liner aluminium foil 3 of the present utility model can also only be arranged on anodal guide pin 4 places of cathode foil 2 sides.Also can only be arranged on negative pole guide pin 5 places of anode foil 1 side.The positive and negative that is arranged on the positive and negative electrode paper tinsel equally all can.
The utility model has increased new current path, has improved the anti-ripple current ability of product, has weakened aluminium tongue burr point discharge under electric field, has improved reliability of products, has prolonged the useful life of product.
Aluminium electrolytic capacitor of the present utility model, during making, earlier liner aluminium foil 3 is pressed in and stings riveting together on cathode foil 2 below the anodal guide pin 4, the negative pole method for making is identical, electrolytic paper is layered on the positive and negative electrode paper tinsel again, begin to reel from anode foil then, seal in a band bottom tube shape aluminum hull with rubber stopper after spooling impregnation.
It is the same that 3 of liner aluminium foils are located at the volume method at the front of cathode foil 2 or anode foil 1 or the back side.
Claims (3)
1, a kind of aluminium electrolytic capacitor, comprise that the thorn riveting has the cathode foil of anodal guide pin, the anode foil that the thorn riveting has the negative pole guide pin, and be laid on electrolytic paper on the positive and negative electrode paper tinsel, it is characterized in that on the anode foil of the aluminium electrolytic capacitor before the described coiling on thorn riveting negative pole guide pin place and/or the cathode foil the anodal guide pin of the thorn riveting place riveting one segment liner aluminium foil that ripostes.
2, aluminium electrolytic capacitor according to claim 1 is characterized in that the riveting of described liner aluminium foil thorn is below the positive and negative electrode guide pin.
