Description
Technical field:
The present invention relates to a kind of capacitor, specifically a kind of aluminium electrolytic capacitor and manufacture method thereof.
Background technology:
At present, in the production technology of existing aluminium electrolytic capacitor, the tongue thorn riveting of its positive and negative guide pin is on the positive and negative electrode aluminium foil, because the burr of positive and negative guide pin tongue directly contacts with electrolytic paper, burr may pierce through electrolytic paper or burr punctures at electric field lower prong discharge causing capacitor short-circuit.
Summary of the invention:
The aluminium electrolytic capacitor and the manufacture method thereof that the purpose of this invention is to provide a kind of product reliability height, long service life.
The present invention adopts following technical scheme to realize its goal of the invention, a kind of aluminium electrolytic capacitor, it comprises by the thorn riveting the positive paper tinsel of anodal guide pin, the negative paper tinsel that the thorn riveting has the negative pole guide pin, between be separated with that electrolytic paper is reeled, impregnation is placed in the band bottom tube shape aluminum hull, with rubber grain sealed aluminum shell opener, be coated with aluminium matter thin slice at the tongue of negative pole guide pin.
Aluminium matter thin slice of the present invention is bonding or press or sting riveting or pad and be added on the negative paper tinsel.
As a kind of improvement of the present invention, be coated with aluminium matter thin slice at the tongue of anodal guide pin; Described aluminium matter thin slice presses or stings riveting on positive paper tinsel.
A kind of manufacture method of aluminium electrolytic capacitor, it comprises cuts, and--------assembling--wearing out--steps such as test are before winding, at the tongue aluminium coating matter thin slice of negative pole guide pin in impregnation in winding in the thorn riveting.
The present invention is by bonding or press or sting riveting or the pad add mode covers on the negative paper tinsel with aluminium matter thin slice.
As a kind of improvement of the present invention, before the winding, also be coated with aluminium matter thin slice at the tongue of anodal guide pin.
The present invention covers aluminium matter thin slice on the positive paper tinsel by pressing or stinging the riveting mode.
Owing to adopt technique scheme, the present invention has realized goal of the invention preferably, this aluminium matter sheet covers positive and negative guide pin tongue, prevent that guide pin tongue burr from directly contacting with electrolytic paper, solved that burr pierces through electrolytic paper and burr punctures at the capacitor short-circuit that the discharge of electric field lower prong causes, aluminium matter thin slice contacts with the positive and negative electrode aluminium foil simultaneously, has increased new current path, improve the anti-ripple current ability and the reliability of product, prolonged the useful life of product.Through test, the short circuit puncture rate that is caused by positive and negative guide pin tongue edge burr is reduced to 5ppm by the 0.2%--5% of former technology, and the ability of bearing ripple current improves 20-50%, prolongs 20-50% useful life.
