Abstract

The invention discloses an aluminium electrolytic capacitor with low inductive reactance. The aluminium electrolytic capacitor with low inductive reactance is composed of a core packing layer, a rubber plug, an aluminium shell, wherein the core packing layer is formed by winding a positive electrode foil in riveted connection with a positive electrode conductive needle, a negative electrode foil in riveted connection with a negative electrode conductive needle, and electrolytic paper between the positive electrode foil and the negative electrode foil through automatic equipment and wrapping the periphery with adhesive tapes; the positive electrode conductive needle and the negative electrode conductive needle are both eccentric conductive needles which are riveted at 1/3 position of the aluminium foils, the equivalent series inductance of the electrode plates is reduced, and the effect of low inductive reactance is achieved. The aluminium electrolytic capacitor has the advantages of low natural inductance, high working resonant frequency and strong high-frequency filter capacity.

Description

A kind of aluminium electrolytic capacitor of low induction reactance
Technical field
The present invention relates to lead wire type aluminum electrolytic capacitor technical field, particularly a kind of aluminium electrolytic capacitor of low induction reactance.
Background technology
At present, the design of electronic circuit particularly LED drives, the lighting fields such as electricity-saving lamp are due to the pressure of production cost, in electric source filter circuit, original L-C filtering is generally all adjusted into simple capacitor filtering, the above high frequency ripple current component of 100KHZ that electrolytic capacitor absorbs increases, because electrolytic capacitor operating frequency is relatively low, generally in 40KHZ left and right, exceed the resonance frequency of electrolytic capacitor, now capacitor becomes induction reactance from capacitive reactance, high order harmonic component cannot absorb, affect the level and smooth of waveform, capacitor internal temperature rise increase simultaneously causes capacitor life-span to shorten, cannot meet the long-life requirement of illuminating product.
Summary of the invention
The object of the invention is, in order to overcome above deficiency, provides the aluminium electrolytic capacitor of the low induction reactance that a kind of inductance is low, resonant frequency of operation is high, High frequency filter ability is strong.
Object of the present invention is achieved through the following technical solutions: a kind of aluminium electrolytic capacitor of low induction reactance, comprise housing, in housing, be provided with core bag and seal rubber plug, core handbag is drawn together anodal guide pin, negative electrode guide needle, anode foil, on anodal guide pin, riveted joint has cathode foil, on negative electrode guide needle, riveted joint has anode foil, between cathode foil and anode foil, be provided with barrier paper, be provided with parcel adhesive tape in barrier paper outer ring, between core bag and housing, between seal rubber plug and housing, sealing is connected, the anodal guide pin of core bag, negative electrode guide needle is core shift guide pin, anodal guide pin is riveted on 1/3 length place of cathode foil, negative electrode guide needle is riveted on 1/4 to 1/3 length place of anode foil, the aluminium tongue of anodal guide pin and negative electrode guide needle is positioned at aluminium and obstructs a side.
Further improvement of the present invention is: positive and negative electrode guide pin aluminium tongue is positioned at aluminium and obstructs a side, only has a reinforcement.
Further improvement of the present invention is: anodal guide pin is riveted on cathode foil 1/3 length place.
The present invention compared with prior art has advantages of:
Aluminium electrolytic capacitor of the present invention anodal guide pin used, negative electrode guide needle are core shift guide pin, core shift guide pin obstructs a side because aluminium tongue is positioned at aluminium, reduce pole plate equivalent series inductance, thereby reach the object of low induction reactance, the present invention has advantages of that self inherent inductance is low, resonant frequency of operation is high, High frequency filter ability is strong.
brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of core shift guide pin;
Fig. 3 is the front view of core shift guide pin;
Number in the figure: 1-housing, 2-core bag, the anodal guide pin of 3-, 4-cathode foil, 5-negative electrode guide needle, 6-anode foil, 7-barrier paper, 8-adhesive tape, 9-plug, the aluminium tongue of 10-guide pin, the aluminium stalk of 11-guide pin
embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
A kind of embodiment of aluminium electrolytic capacitor of low induction reactance as Figure 1-3: comprise housing 1, in housing 1, be provided with core bag 2 and seal rubber plug 9, core bag 2 comprises anodal guide pin 3, negative electrode guide needle 5, anode foil 6, on anodal guide pin 3, riveted joint has cathode foil 4, on negative electrode guide needle 5, riveted joint has anode foil 6, between cathode foil 4 and anode foil 6, be provided with barrier paper 7, be provided with parcel adhesive tape 8 in barrier paper 7 outer rings, between core bag 2 and housing 1, between seal rubber plug 9 and housing 1, seal and be connected, the anodal guide pin 3 of core bag 2, negative electrode guide needle 5 is core shift guide pin, anodal guide pin 3 is riveted on 1/3 length place of cathode foil 4, negative electrode guide needle 5 is riveted on 1/4 to 1/3 length place of anode foil 6, the aluminium tongue 10 of anodal guide pin 3 and negative electrode guide needle 5 is positioned at aluminium stalk 11 1 sides.
Core shift guide pin obstructs a side because aluminium tongue is positioned at aluminium, riveted joint position on aluminium foil can be adjusted to 1/3 place of aluminium foil length, reduce pole plate equivalent series inductance, improve the resonant frequency of operation of aluminium electrolytic capacitor, resonance frequency is increased to 100KHZ by 40KHZ, high frequency E SR declines 10%, thereby reaches the object of low induction reactance.Have advantages of that self inherent inductance is low, resonant frequency of operation is high, High frequency filter ability is strong.
