Abstract
The utility model discloses an aluminum electrolytic capacitor, which comprises a cathode foil, an anode foil, electrolytic paper wrapping the cathode foil and the anode foil, and a first leading-out strip and a second leading-out strip respectively arranged on the cathode foil and the anode foil, wherein the anode foil adopts a voltage-applying negative foil. Compared with the prior art, the aluminum electrolytic capacitor has the advantages that by using the negative foil to apply voltage (more than 3V), the backward voltage resisting capability of the capacitor is improved, and the ripple resisting capability is greatly improved finally, so that the capacitor can well meet the use requirements of welders and transducers.
Description
[technical field]
The utility model relates to a kind of electric elements, refers to a kind of aluminium electrolytic capacitor especially.
[background technology]
, social demand amount increasingly mature along with device fabrication technology such as DC welder, frequency converter, ups powers also increases sharply, and its quality is had higher requirement.The aluminium electrolytic capacitor that in these equipment, uses, its quality requirement is higher.
Existing aluminium electrolytic capacitor, it comprises that fuse, aluminum hull, two lead chaff and cover plate, fuse is packed in the aluminum hull, and by cover plate for sealing.Said fuse is twined and is formed by cathode foil, anode foil, electrolytic paper.The negative paper tinsel voltage of existing this kind aluminium electrolytic capacitor is zero.Because negative paper tinsel voltage is zero, the anti-reverse withstand voltage deficiency of this kind capacitor, thus cause anti-ripple indifferent, in use, break down easily even damage.
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 to have the defective of drawing art now in order to solve, and the spy provides a kind of anti-reverse voltage the strong and strong aluminium electrolytic capacitor of anti-ripple ability.
To achieve these goals; The utility model adopts following technical scheme: a kind of aluminium electrolytic capacitor; It comprises cathode foil, anode foil, hold the electrolytic paper of cathode foil and anode foil and be separately positioned on cathode foil and anode foil on first lead and second lead; Wherein, said anode foil adopts the negative paper tinsel of pressurization.
Preferably, the voltage of the negative paper tinsel of said pressurization is more than the 3V.
Preferably, said first lead and second lead are riveted on respectively on cathode foil and the anode foil.
Preferably, said cathode foil, anode foil, hold the electrolytic paper of cathode foil and anode foil and be separately positioned on cathode foil and anode foil on first lead and second lead twine the formation fuse together.
Compared with prior art, the utility model aluminium electrolytic capacitor makes the anti-reverse voltage ability of capacitor improve through using negative paper tinsel pressurization (more than the 3v), and final anti-ripple ability promotes greatly, better meets the instructions for use of welding machine and these equipment of frequency converter.

Fig. 1 is the structural representation of the utility model aluminium electrolytic capacitor slugs;
Fig. 2 is the cathode foil structural representation of the utility model aluminium electrolytic capacitor;
Fig. 3 is the anode foil structural representation of the utility model aluminium electrolytic capacitor.
[embodiment]
Please refer to Fig. 1 to shown in Figure 3; The utility model aluminium electrolytic capacitor; It comprises: aluminum hull (not shown), cover plate (not shown), cathode foil 11, anode foil 12, hold the electrolytic paper 13 of cathode foil 11 and anode foil 12 and be separately positioned on cathode foil and anode foil on lead 14 and lead 15, said lead 14,15 is riveted on said cathode foil and the anode foil.
Said cathode foil, anode foil, hold the electrolytic paper of cathode foil and anode foil and be separately positioned on cathode foil and anode foil on first lead and second lead twine the formation fuse together.
The utility model aluminium electrolytic capacitor; Through using negative paper tinsel pressurization, generally be pressurised into more than the 3v, make the anti-reverse voltage ability of capacitor improve; Final anti-ripple ability promotes greatly, better meets 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.
