Abstract

La présente invention concerne un condensateur électrolytique humide (10) comprenant une anode, un fil d'anode (220), un électrolyte, un boîtier (12) ayant une paroi qui définit un orifice de fil d'anode (34), et un ensemble d'étanchéité (300). L'ensemble d'étanchéité (300) est raccordé au boîtier (12) au niveau de l'orifice de fil d'anode (34), et une partie du fil d'anode (220) s'étend à travers celui-ci. L'ensemble d'étanchéité (300) comprend un tube isolant (306), une plaque métallique (301), et une bague élastomère (311). Le tube reçoit le fil d'anode (220) et a une première partie s'étendant à travers l'orifice de fil d'anode (34) et une seconde partie située dans un intérieur du boîtier (12). La plaque est adjacente à une surface extérieure (27) de la paroi, couvre l'orifice de fil d'anode (34), et contient un orifice. La bague est positionnée adjacente à une surface intérieure de la paroi et contient un orifice.
