Abstract

La présente demande de brevet concerne un fusible, un circuit de véhicule pour un véhicule électrique et un véhicule électrique. Le fusible présente une direction longitudinale et une direction transversale et inclut : une bague présentant une cavité de trou traversant s'étendant dans la direction longitudinale et destinée à recevoir du sable de quartz et deux surfaces d'extrémité dans la direction longitudinale ; un corps de fusible, logé dans la cavité de trou traversant ; et deux lames de contact, positionnées à deux extrémités de la cavité de trou traversant et jointes de manière conductrice au corps de fusible. Au moins l'une des lames de contact comprend une première section entrant en contact étanche direct avec l'une des surfaces d'extrémité de la bague, en recouvrant la cavité de trou traversant et une section de bras en surplomb s'étendant à partir de la première section. La section de bras en surplomb inclut une deuxième section s'étendant, dans une direction perpendiculaire à la direction longitudinale, hors de la bague. Figure pour l’abrégé : Fig. 5
