  • An outer two channels 80 are straight and 13mm long.
  • An inner two channels 80 have a straight line length of 9.9mm, so the cable is obliged to curve down and back up to make the 13mm distance.

Abstract

La présente invention porte sur un système pour connecter un appareil à une alimentation électrique, qui emploie des dispositifs de raccord de fil (10) qui fournissent une connexion électrique à une unique extrémité dénudée d'un fil ou d'un câble par l'intermédiaire d'un canal de contact (42) qui peut être glissé sur une tige de connexion en saillie sur un dispositif d'assemblage de raccord de fil tel qu'une boîte de jonction électrique, une unité consommatrice d'électricité, une prise femelle électrique ou un commutateur électrique. Les canaux de contact (42) peuvent permettre à plus d'un dispositif de raccord de fil (10) d'être glissé sur ceux-ci au même moment. Des dispositifs de raccord de fil (10) peuvent être fixés ensemble et l'ensemble connecté glissé sur des réseaux espacés de tiges de connexion en saillie. Un outil de dénudage et d'insertion de fil (64) est utilisé pour réaliser une connexion électrique sécurisée et sûre d'un fil ou d'un câble individuel à un dispositif de raccord de fil (10). L'outil (64) accepte une insertion d'une extrémité coupée d'un fil ou d'un câble, dénude les deux gaines d'isolation intérieure et extérieure du câble ou du fil. L'outil insère ensuite l'extrémité de fil nu dénudé dans un dispositif de raccord de fil (10) qui a été inséré de manière amovible et maintenu dans l'outil, soit de manière unique soit fixé en groupes. L'outil provoque ensuite l'application électrique de l'extrémité de fil nu dans le canal de contact (42) du dispositif de raccord de fil (10), et libère ensuite le dispositif de raccord de fil maintenu (10) ou un groupe de dispositifs de raccord de fil mutuellement fixés (10), chacun avec une connexion de fil isolée de manière sécurisée qui peut être insérée sans risque personnel sur une tige de connexion en saillie. L'outil (64) stocke des gaines dénudées à l'intérieur de celui-ci, ou éjecte automatiquement des gaines dénudées.
