Abstract

L'invention concerne un système de test de faisceau de câbles conçu pour faciliter et pour harmoniser l'intégration de modules électriques de test dans la table de test, ce qui le rend plus polyvalent en termes de diversité de familles de faisceaux de câbles pouvant être testées sur le même équipement. Afin d'atteindre ces objectifs, il existe un besoin de changer le concept classique sous-jacent à un système classique de test, de décentraliser le traitement associé au test lui-même, à l'exception de l'utilisation de bâtis ou de cartes d'interface et d'extension. Le système de test développé est destiné à une utilisation dans l'industrie du câblage et vise à faciliter et à harmoniser l'intégration de modules électriques de test dans la table de test, en rendant ladite table plus souple et apte à s'adapter au test de différents types de faisceaux de câbles.
