Abstract

L'invention concerne un support de câble pour un module à cellules solaires. Le support de câble selon l'invention présente une grande longévité et permet de monter facilement le câble de câblage d'un module à cellules solaires sur un cadre et de le remplacer aisément. Un support de câble (10) pour un module à cellules solaires comprend : une paire de pièces de suspension (11) qui viennent en contact avec la surface supérieure d'une section d'extension (3c) dans un cadre (3) d'un module à cellules solaires (1) ; une paire de pièces qui s'étendent vers le bas (12), qui s'étendent depuis une extrémité de celui-ci, situées à proximité d'un trou traversant (3d) entre la paire de pièces de suspension (11), vers le bas à travers le trou traversant (3d) en direction du côté inférieur ; une pièce de soutien de câble (13) qui est rattachée aux extrémités inférieures de la paire de pièces qui s'étendent vers le bas (12) et qui est conçue pour soutenir un câble de câblage (4) ; et des pièces inclinées (14) qui s'étendent chacune diagonalement vers le haut depuis l'extrémité de celui-ci et qui sont disposées plus loin que le trou traversant (3d) entre la paire de pièces de suspension (11), vers l'autre extrémité de celui-ci. Le support de câble est intégralement formé en utilisant un fil métallique.
