Abstract

L'invention concerne un connecteur fil à fil pour un câble, ledit connecteur comprenant : une coque comportant un premier trou traversant, le câble passant à travers ledit trou traversant et passant axialement à travers la coque le long de la coque ; un tuyau d'adaptation comportant une cavité de tuyau s'étendant depuis une extrémité jusqu'à l'autre extrémité en passant à travers le tuyau d'adaptation et comportant un rebord agencé sur le tuyau d'adaptation et faisant saillie depuis le tuyau d'adaptation ; un manchon d'isolation de borne comportant un second trou traversant qui passe à travers celui-ci. Une extrémité du tuyau d'adaptation est insérée dans le premier trou traversant. Le rebord est plus large que le premier trou traversant et presse axialement contre la partie d'extrémité de la coque, et est situé à l'extérieur du premier trou traversant. L'autre extrémité du tuyau d'adaptation est raccordée au manchon d'isolation de borne. Avec le connecteur décrit ci-dessus, une séparation et une connexion fil à fil peuvent être réalisées rapidement afin de raccorder ensemble et de manière commode au moins deux câbles.
