Abstract

La présente invention concerne un composant de connexion et un faisceau de câbles qui permettent de supprimer une réduction de la performance de blindage et dont l'extensibilité permet une compatibilité aisée avec un changement de caractéristiques.　Un composant de connexion (10) comprend une partie qui, lorsque les parties de blindage respectives (62) d'une pluralité de câbles blindés (60) sont connectées électriquement par des parties de drain respectives (70), est positionnée entre deux câbles blindés correspondants (60). Le composant de connexion (10) comporte une partie de réception (13, 14, 42, 43, 49, 54) qui reçoit une partie à laquelle une partie de drain (70) et une partie de blindage (62) sont connectées et une partie de jonction (23, 28, 45, 46) qui est destinée à être connectée à un autre composant de connexion (10).
