Abstract

L'invention concerne une structure de connexion entre un premier câblage (11) équipé d'une première âme (10), et un second câblage (13) équipé d'une seconde âme (12) électriquement connectée à la première âme (10). Cette structure de connexion est équipée : d'une partie connexion (15) dans laquelle la première et la seconde âme (10, 12) sont électriquement connectées; et d'un boîtier (16) dans lequel la partie connexion (15) est admise. Ainsi, la partie connexion (15) est protégée par le boîtier (16), y compris en cas d'application sur le premier et/ou le second câblage (11, 13) d'une force telle qu'un pliage, une traction, une torsion, ou similaire. Par conséquent, il est possible d'empêcher l'apparition de défauts tels qu'une déformation de la partie connexion (15), ou similaire. Il est donc également possible d'améliorer la fiabilité électrique du premier et du second câblage (11, 13) au niveau de la partie connexion (15).
