The condenser has a fixedly connected shell and a cover plate, among which, an insulator jackets the shell, a cylindrical core bag is winded in the shell with electrolytic paper isolating the anode foil and the cathode foil, five welding pins are riveted on the plate, two groups of lead-out strips are riveted under the cover plate, the other ends of them are riveted with the anode foil and the cathode foil separately. The manufacturing method includes: a, cutting Al foils and electrolytic paper, b, riveting, c, immersing with the crossed positive and negative voltages, d, covering, e, ageing, f, selecting, separating and packaging.
Description
Technical field
The present invention relates to technical field of electrolytic, especially a kind of five needle type cover plate aluminum electrolytic capacitor and manufacture method thereof.
Background technology
Existing aluminium electrolytic capacitor has two-needle type and four needle type cover plate aluminum electrolytic capacitors, be that riveted joint has two or four root bead pins on the cover plate of aluminium electrolytic capacitor, by capillary that aluminium electrolytic capacitor is fixing in the circuit board, this structure can only be applicable to the aluminium electrolytic capacitor that volume is less, when volume is big, the vibration of fuselage, can cause the aluminium electrolytic capacitor rosin joint, aluminium electrolytic capacitor waves and causes that connection is loosening, even might cause the broken needle phenomenon, therefore present aluminium electrolytic capacitor for large volume generally adopts hoop sleeve on the shell of aluminium electrolytic capacitor, again that clip is fixing in the circuit board, this structure connects firm, but because suit clip again on the shell of aluminium electrolytic capacitor, this has just increased aluminium electrolytic capacitor installation site in the circuit board.As everyone knows, what we pursued always is miniaturization, the low cost of electric equipment, and adopts the fixing mode of clip obviously not meet this theory.The bigger aluminium electrolytic capacitor of while volume, its core bag is also bigger, is not easy during impregnation to soak into, and generally needs impregnation more than 20 hours, so the corresponding increase of production cost.
Summary of the invention
In order to overcome the deficiency of existing large volume aluminium electrolytic capacitor, the invention provides a kind of five needle type cover plate aluminum electrolytic capacitor and manufacture method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of five needle type cover plate aluminum electrolytic capacitor, have aluminum hull and cover plate, cover plate is fixedlyed connected with aluminum hull, aluminum hull is with insulator outward, be provided with anode foils, Cathode Foil and electrolytic paper in the aluminum hull, electrolytic paper is every be wound into cylindric core bag between anode foils and Cathode Foil, riveted joint has five root bead pins on the cover plate, the cover plate below is provided with two groups of leads, two groups of lead one ends are riveted with cover plate respectively, and the other end is riveted with anode foils, Cathode Foil respectively.
The product contact resistance is little, impedance is little in order to make, anti-ripple current is big, capacity is big, and described every group of lead is at least one.
A kind of manufacture method of five needle type cover plate aluminum electrolytic capacitor has following processing step:
A. cut aluminium foil and electrolytic paper;
B. wrap riveting, with an end of two groups of leads respectively with anode foils, Cathode Foil riveted joint, with electrolytic paper every between anode foils, Cathode Foil, being wound into cylindric core bag; Again the other end of the lead of core bag there is the cover plate riveted joint of five root bead pins respectively with riveted joint;
C. the core bag is intersected positive negative pressure impregnation, vacuumize, the core bag is immersed electrolyte, add the 0.01MPa negative pressure earlier, impregnation half an hour, insert the 0.4MPa malleation again, impregnation half an hour, insert the 0.01MPa negative pressure again, impregnation half an hour, so positive negative pressure was intersected impregnation more than 8 hours, soaked into to the core bag;
D. the group cover is assembled into naked product capacitor with flooding good core bag and cover plate and aluminum hull, and naked product capacitor is put insulating sleeve;
E. seasoned;
F. sorting and visual examination;
G. pack.
The invention has the beneficial effects as follows, five needle type cover plate aluminum electrolytic capacitor of the present invention, contact resistance is little, impedance is little, anti-ripple current is big, capacity is big, with being connected firmly of wiring board, saves installing space; Five needle type cover plate aluminum electrolytic capacitor manufacture method of the present invention, the impregnation time foreshortens to 8 hours by original more than 20 hours, shortened the impregnation time greatly, thereby reduced production cost.
