Abstract

La présente demande de brevet concerne un fusible, un circuit de véhicule pour un véhicule électrique et un véhicule électrique. Le fusible a une direction longitudinale et une direction transversale et comprend : un manchon, comportant une cavité sous forme de trou traversant s'étendant dans la direction longitudinale et destinée à recevoir du sable de quartz ; un corps de fusible, logé dans la cavité sous forme de trou traversant et comportant une pluralité d’ouvertures espacées les unes des autres dans la direction transversale ; et deux lames de contact, positionnées au niveau des deux extrémités de la cavité sous forme de trou traversant et chacune soudées au corps de fusible par une plaque conductrice. Une couche de substance d'extinction d'arc est prévue sur le corps de fusible. Un bord latéral de la couche de substance d’extinction d’arc est en contact avec les bords de deux ouvertures adjacentes quelconques parmi la pluralité d'ouvertures de sorte que la couche de substance d'extinction d'arc soit située à proximité d'un espace transversal minimal entre les bords des deux ouvertures. Figure pour l’abrégé : figure 1
