Abstract
Cet ensemble cathode (C) comprend : - un corps de cathode (1) en matériau carboné, ledit corps de cathode étant pourvu d'au moins une fente (17, 17'), ladite fente étant pourvue de parois latérales (171, 172, 171', 172') parallèles à une direction longitudinale (A17, A17') de ladite fente ; - au moins une barre collectrice de cathode (3, 3') en un matériau métallique, ladite barre de cathode étant pourvue de parois latérales (33, 34), qui sont en contact avec lesdites parois latérales de ladite fente. Selon l'invention, ladite barre de cathode comprend deux éléments de barre (7, 9), chaque élément de barre étant pourvu d'une paroi latérale principale (73, 93) qui est en contact avec une paroi latérale respective (171, 172) de ladite fente, ainsi qu'une paroi conique (77, 97), les deux parois coniques desdits éléments de barre formant une ligne de contact (37) entre ces deux éléments de barre.
