Abstract

Pour fabriquer un ensemble (1) constitué d'une partie tube en plastique (2) présentant au moins un insert tube-fils (4 à 7) et un connecteur de borne (3), un premier groupe de composants conducteurs électriques est préfabriqué. Des composants conducteurs (9 à 12) du groupe de composants conducteurs assurent, à l'état monté, une connexion électrique avec l'au moins un insert tube-fils (4 à 7). Une configuration de composant conducteur (8) est séparée du groupe de composants conducteurs préfabriqués. La configuration de composant conducteur (8) est mise en contact électrique avec l'au moins un insert tube-fils (4 à 7). Le connecteur de borne (3) est relié à la partie tube en plastique (2). Il en résulte un procédé de fabrication d'un ensemble qui est approprié pour la production en masse. Le groupe de composants conducteurs est un constituant d'une grille de connexion multiple qui comprend une pluralité de configurations de composant conducteur (8) sélectionnables différentes qui peuvent être spécifiées en fonction des exigences de contact électrique par sélection de composants conducteurs appropriés.
