Abstract
The utility model relates to an aluminum electrolytic capacitor, comprising an anode foil, a cathode foil and an electrolytic paper lapped with the anode foil and the cathode foil; wherein, the cathode foil is riveted together with a guide chaff, and a liner cathode foil is arranged at the riveting position of the cathode foil and the guide chaff additionally. Compared with the prior art, the aluminum electrolytic capacitor of the utility model enables the internal breakdown of a capacitor to be reduced effectively by placing the liner cathode foil at the riveting position of the cathode foil and the guide chaff, improving the service life of the capacitor and a ripple resistant capability, and better satisfying the use requirements of the devices, such as a welding machine, a UPS power supply and a frequency converter.
Description
[technical field]
The utility model relates to a kind of electric elements, relates in particular to a kind of improved aluminium electrolytic capacitor.
[background technology]
Its inner anode foil of present general capacitor with lead chaff riveted joint place linerless anode foil; Paper tinsel edge in the process of cutting has and small burr and the surperficial paper tinsel ash that can adhere to only a few because its negative pole is led; When using this capacitor, these burrs and paper tinsel ash cause this capacitor breakdown to cause its inefficacy easily and can not bear too high ripple current.
, social demand amount increasingly mature along with device fabrication technology such as DC welder, frequency converter, ups powers also increases sharply; Its quality is had higher requirement; The quality requirement of the aluminium electrolytic capacitor that in these equipment, uses is also higher; Therefore, existing aluminium electrolytic capacitor is difficult to satisfy industrialized demand.
In view of above drawback, be necessary to provide a kind of improved aluminium electrolytic capacitor to overcome above-mentioned defective in fact.
[utility model content]
The purpose of the utility model is exactly in order to address the deficiencies of the prior art, and the spy provides a kind of simple in structure, long service life, aluminium electrolytic capacitor that anti-ripple property is strong.
To achieve these goals; The utility model adopts following technical scheme: a kind of aluminium electrolytic capacitor; It comprises cathode foil, anode foil and the electrolytic paper that holds the positive and negative electrode paper tinsel; Anode foil with lead chaff and be riveted together, wherein, said anode foil with lead chaff riveted joint place and add the liner anode foil.
Preferably, the bottom surface of said liner anode foil is covered in anode foil and leads chaff riveted joint place.
Preferably, said cathode foil, anode foil, electrolytic paper and liner anode foil are also twined in the form of sheets and are formed fuse.
Compared with prior art; The utility model aluminium electrolytic capacitor; Through anode foil with lead chaff riveted joint place and add the liner anode foil; Make that the internal breakdown of capacitor is effectively reduced, improved capacitor useful life and anti-ripple ability, better meet the instructions for use of welding machine, ups power and these equipment of frequency converter.
[description of drawings]
Fig. 1 is the inner structural representation of the utility model aluminium electrolytic capacitor;
Fig. 2 is the anode foil of Fig. 1 capacitor and leads the structural representation that chaff riveted joint place adds the liner anode foil.
[embodiment]
Please refer to Fig. 1, shown in Figure 2; The utility model aluminium electrolytic capacitor, it comprises: aluminum hull, cover plate, cathode foil, anode foil and the electrolytic paper that holds the positive and negative electrode paper tinsel, anode foil with lead chaff and be riveted together; Wherein, said anode foil with lead chaff riveted joint place and add the liner anode foil.
In the utility model, the bottom surface of said liner anode foil is covered in anode foil and leads chaff riveted joint place.Said cathode foil, anode foil, electrolytic paper and liner anode foil are also twined in the form of sheets and are formed fuse.Again fuse is packed in the aluminum hull, and it is sealed with cover plate.
In sum; The utility model aluminium electrolytic capacitor; Through anode foil with lead chaff riveted joint place and add the liner anode foil; Make that the internal breakdown of capacitor is effectively reduced, improved capacitor useful life and anti-ripple ability, better meet the instructions for use of welding machine, ups power and these equipment of frequency converter.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
