Abstract
A novel anti-knock aluminum electrolytic capacitor comprises an aluminum shell, a capacitor core and an insulation rubber cover; the periphery of the inner wall of the aluminum shell is provided with supporting columns; the supporting columns are formed in a manner that the supporting columns are in integrated arrangement with the aluminum shell; the capacitor core is arranged in the cavity of the aluminum shell; an anode pin and a cathode pin are led out from the capacitor core and pass through the insulation cover; the front end surface of the insulation rubber cover is provided with supporting pins which are distributed side by side with the anode pin and the cathode pin; and the bottom of the inner wall of the aluminum shell is provided with an explosion-proof groove. The novel anti-knock aluminum electrolytic capacitor of the utility model has the advantages of convenience, favorable anti-knock performance, high safety performance, excellent heat dissipation performance, low cost and the like. The periphery of the inner wall of the aluminum shell is provided with the supporting columns, and therefore, short-circuiting or fracture caused by collision of the anode lead foil bar and the cathode lead foil bar cased by violent upward and downward swing can be effectively avoided; a thermal conduction insulating medium is filled inside the supporting columns, such that the cooling time of the novel anti-knock aluminum electrolytic capacitor is shortened by 40% compared with a conventional capacitor, and therefore, the service life of the novel anti-knock aluminum electrolytic capacitor can be ensured, and capacitor failure caused by difficult heat dissipation can be avoided.
Description
Technical field
The utility model relates to capacitor technology field, especially relates to a kind of novel earthquake-proof aluminium electrolytic capacitor.
Background technology
Aluminium electrolytic capacitor is paper tinsel formula winding type structure, and anode is aluminum metallic foil, and negative electrode is Working electrolyte, by lead-in wire paper tinsel, by the method for cold riveting, draws anode pin and negative electrode pin.Aluminium electrolytic capacitor at present application is arranged on the vibrations equipment such as engine, while working due to equipment under continuous vibrating state, and aluminium electrolytic capacitor ability volume is large, own wt is heavier, therefore easily there is pin breakage and form open-circuit condition and lose proper function.
Summary of the invention
The utility model object is to provide a kind of novel earthquake-proof aluminium electrolytic capacitor.To solve the technical problems such as the existing use inconvenience of prior art, poor seismic behavior, poor radiation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel earthquake-proof aluminium electrolytic capacitor, comprises aluminum hull, capacitor core, insulating cement lid; Described aluminum hull inner peripheral wall is provided with support column, and this support column and aluminum hull are wholely set and form; Described capacitor core is arranged in aluminum hull cavity, and this capacitor core leads to anode pin and negative electrode pin and covers through insulating cement, and the front end face of described insulating cement lid is provided with the supporting pins with anode pin and the adjacent arrangement of negative electrode pin; Described aluminum hull inwall bottom is provided with explosion-proof groove.
As preferably, described support column is hollow, in this support column closed cavity, is filled with heat conductive insulating medium.
As preferably, described in be arranged on aluminum hull inner peripheral wall support column be 3～6.
As preferably, the explosion-proof groove that described aluminum hull inwall bottom arranges is extended with fan groove to surrounding, and wherein fan groove is provided with 3～6, and the position distributing is corresponding in the position of sidewall distribution with support column.
The utlity model has easy to use, anti-seismic performance good, security performance is high, good heat dissipation, low cost and other advantages.By support column being set in aluminum hull inwall surrounding, effectively preventing that strong rocking up and down from causing positive and negatively draws chaff collide short circuit or fracture, and support column strengthened aluminum hull main body simultaneously, makes it not yielding, the utility model falls from 2m, and internal capacitance fuse can not be shifted; Due to support column lumen loading heat conductive insulating medium, than the temperature fall time of conventional capacitor, shortened 40%, guaranteed useful life, effectively prevent that heat is difficult for shedding and causes capacitor to lose efficacy.
Accompanying drawing explanation
