Herstellungsverfahren für einen Elektrolytkondensator

摘要

An electrolytic capacitor is manufactured by coiling an anode foil 2 with a lead terminal 1 fixed thereto, a cathode foil 3 with a lead terminal 1 fixed thereto, and a separator 5 into a capacitor assembly 7, placing a sealing cap 8 of an elastomeric material on the lead terminals which are inserted through respective holes defined in the sealing cap 8 after an adhesive 13 is applied in the holes, thereby attaching the sealing cap 8 to the capacitor assembly 7, and heating the adhesive until the adhesive 13 is fully set, thereby bonding the lead terminals 1 and the sealing cap 8 to each other. Thereafter, the capacitor assembly 7 is impregnated with an electrolytic solution, and the capacitor assembly 7 with the sealing cap 8 attached thereto is inserted into a case 9 and sealing the capacitor assembly 7 in the case 9. The electrolytic capacitor thus manufactured has a relatively simple structure to effectively present the electrolytic solution from leaking out, and also has a long service life and is highly reliable. $$
