Abstract
The utility model relates to the technical field of an aluminum electrolytic capacitor, which particularly relates to a double guide pin, a cathode aluminum foil, an anode aluminum foil and an electrolysis paper of at least one layer. The guide pin is riveted with the anode aluminum foil and the cathode aluminum foil. The electrolysis paper is fixed between two aluminum foils. At least one padding paper is arranged on the back of the anode aluminum foil and the cathode aluminum foil. Burrs formed by the guide pin and the aluminum foil are covered by the padding paper. The utility model has the beneficial effect that the padding paper is capable of resisting the sentus when the sentus is twisted with the electrolysis paper by covering the sentus. Defects including explosion and short circuit or breakdown in the capacitor caused by burrs discharging or the burrs penetration into the electrolysis paper are well prevented.
Description
Technical field:
The utility model relates to the capacitor technology field, particularly structural improvement aluminium electrolytic capacitor.
Background technology:
Existing aluminium electrolytic capacitor generally comprises guide pin, positive pole and changes into paper tinsel, negative pole aluminium foil, the above electrolytic paper of one deck at least; In production technology, the tongue of its positive and negative guide pin is riveted on the positive and negative electrode aluminium foil, electrolytic paper is clipped between two aluminium foils, in reality processing, magic flower produces burr during owing to the thorn riveting, when reeling with electrolytic paper, burr may pierce through electrolytic paper or burr causes defectives such as capacitor short-circuit puncture, blast in the discharge of electric field lower prong.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art to have structure improved aluminium electrolytic capacitor.
For achieving the above object, the utility model adopts following technical scheme:
It comprises two guide pins, cathode aluminum foil, anode aluminium foil and the above electrolytic paper of one deck at least, guide pin respectively with cathode aluminum foil and anode aluminium foil and riveted joint, electrolytic paper places between the two-layer aluminium foil, be equipped with one deck interleaving paper at least at the back side of cathode aluminum foil and anode aluminium foil, interleaving paper covers the burr of guide pin and aluminium foil riveted joint formation.
Described interleaving paper is an electrolytic paper.
The beneficial effects of the utility model are: adopted interleaving paper to cover the burr of guide pin and aluminium foil riveted joint formation, when reeling with electrolytic paper, interleaving paper just can stop burr, causes defectives such as capacitor short-circuit puncture, blast thereby avoided burr to penetrate electrolytic paper or burr in the discharge of electric field lower prong.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial exploded view of the present utility model.
Embodiment:
The following stated only is a better embodiment of the present utility model, does not therefore limit protection range of the present utility model.
See accompanying drawing 1,2, the utility model comprises two guide pins 1, cathode aluminum foil 2, anode aluminium foil 3 and the above electrolytic paper 4 of one deck at least, guide pin 1 respectively with cathode aluminum foil 2 and anode aluminium foil 3 and riveted joint, electrolytic paper 4 places between the two-layer aluminium foil, be equipped with one deck interleaving paper 5 at least at the back side of cathode aluminum foil 2 and anode aluminium foil 3, interleaving paper 5 covers guide pin 1 and rivets the burr that forms with aluminium foil.
In actual production process, interleaving paper 5 adopts electrolytic paper preferable, and preferably long interleaving paper 5, in winding process, interleaving paper 5 can be wound into fuse 6 together, also interleaving paper 5 is fixed in the winding process.In addition, when stacking aluminium foil, can the burr that two aluminium foils and guide pin 1 forms is relative, so just need can cover the burr that forms on two aluminium foils adding one deck interleaving paper 5 between two aluminium foils.
Interleaving paper 5 can adopt aluminium foil, when reeling its no longer with cathode aluminum foil 2 and anode aluminium foil 3 riveted joints, avoiding forming new burr, but, adopt aluminium foil that the impedance of aluminium electrolytic capacitor is increased, and contact in the time of to cause electrolyte dipping core bag with cathode aluminum foil 2 and anode aluminium foil 3 and to be difficult for soaking into.
Interleaving paper 5 directly adopts the effect of electrolytic paper to adopt aluminium foil better, can not cause the problems referred to above.
