Terminal connection and sealing method for electrolytic capacitor - includes top can sealing disc with central and outer connection conductors

摘要

An electrolytic capacitor is constructed so that both with connecting wires taken from the top of the unit. Prime consideration is that no internal short circuit should occur during mfr. The capacitor (1) is inserted in an outer can (2) so that one capacitor end terminal (9) makes electrical contact with the inside of the can (2). The opposite end terminal (8) makes contdact with a rivet (12) through the centre of the sealing disc (3). The sealing disc (3) comprises an insulating material (3) with an elasticised under coating (11) to seal the can by pressing against preformed shoulders (5) and a conducting outer ring coating (10) onto which the sides (4) of the can (2) are burred over forming a mechanical and electrical seal. The capacitor connecting wires (6, 7) are connected to the centre rivet (12) and the conducting outer ring (10) of the sealing disc (3).
