Abstract

L'invention concerne une barre collectrice destinée à réaliser une connexion électrique, composée d'un matériau électroconducteur de conductivité élevée, s'étendant dans une direction longitudinale X et constituée de plusieurs segments adjacents (1, 3), la barre collectrice pouvant être fixée à une surface support au moyen d'au moins deux segments de fixation (1). La barre collectrice comporte au moins un segment de compensation (3) disposé entre deux segments de fixation (1) et conçu géométriquement de telle manière que d'une part, le segment de compensation présente un plus grand pouvoir de dissipation de la chaleur, par rapport aux segments adjacents de la barre collectrice, en raison d'une convection et/ou d'un rayonnement de chaleur supérieurs, et que d'autre part, en cas de dilatation thermique de la barre collectrice à l'état fixé, une déviation locale du matériau du segment de compensation (3) est rendue possible perpendiculairement à la direction X par déformation locale du segment de compensation (3). Le segment de compensation (3) comporte au moins une entretoise de liaison (4, 4') reliant les deux segments de la barre collectrice adjacents au segment de compensation (3). La barre collectrice est caractérisée en ce que le segment de compensation (3) comporte des entretoises de liaison courbées (4, 4') sans fentes de passages présentes entre les entretoises de liaison, des entretoises de liaison (4, 4') adjacentes étant respectivement courbées de façon alternative dans une direction Y ou dans une direction Y perpendiculaire à la direction X, et en ce que les entretoises de liaison (4, 4') sont fabriquées par découpe sans chutes et façonnage ultérieur.
