Title
(EN) CONNECTION METHOD, EQUIPOTENTIAL SHUNT CONNECTION AND EQUIPOTENTIAL BONDING CURRENT RETURN NETWORK IN A NON-CONDUCTIVE ARCHITECTURE
(FR) PROCÉDÉ DE RACCORDEMENT, RACCORD DE DÉRIVATION ÉQUIPOTENTIEL ET RÉSEAU DE RETOUR COURANT À LIAISON ÉQUIPOTENTIELLE DANS UNE ARCHITECTURE NON CONDUCTRICE
Abstract
(EN) The aim of the invention is to produce electrically efficient equipotential connections in terms of resistivity between portions of a current return network of a non-conductive architecture, such as an airplane fuselage. The approach adopted according to the invention is to impart an equipotential bonding function to an aluminum cable having a large cross-section, said bond being electrically connected, via direct contact, to as many pieces of equipment as is physically possible. According to one embodiment, an electrical connection assembly of an aircraft fuselage (100) having a composite skin comprises on-line shunt connections (2) for electrically interconnecting an aluminum alloy cable (1), having a large cross-section and serving as an equipotential bond, to brackets (113, 141) for primary current return networks and to brackets (111) for electrical devices via connections (202). Each on-line shunt connection (2) comprises a central sleeve (2m) for directly electrically contacting the cable (1), end portions for being assembled to the cable (1) by crimping, and an attachment means (2p) for attaching to the bracket (111) of the equipment. Each of the ends of the sleeve (2m) have seal accommodated therein. Each interconnection has two sealed areas, which surround a central contact area formed by means of window-stripping.
(FR) L'invention vise à réaliser des liaisons équipotentielles électriquement performantes en termes de résistivité entre des parties de réseau de retour courant d'une architecture non conductrice telle qu'un fuselage d'avion. L'approche suivie par l'invention est de conférer à un câble de grosse section en aluminium une fonction de type liaison équipotentielle, cette liaison étant raccordée électriquement par contact direct à autant d'équipements qu'il est physiquement possible d'en connecter. Selon un mode de réalisation, un ensemble de raccordement électrique d'un fuselage d'aéronef (100) à peau composite comporte des raccords de dérivation en ligne (2) d'interconnexion électrique entre un câble (1) de forte section à base d'alliage d'aluminium, servant de liaison équipotentielle via des raccords (202) à des supports (113, 141 ) de réseaux primaires de retour de courant, et des supports (111) d'équipements électriques. Chaque raccord de dérivation en ligne (2) comporte un manchon central (2m) de contact électrique direct avec le câble (1), des portions d'extrémité, d'assemblage au câble (1) par sertissage et un moyen de fixation (2p) pour venir se fixer au support (111) de l'équipement. Les extrémités du manchon (2m) logent chacune un joint d'étanchéité. Chaque interconnexion présente deux zones étanches qui entourent une zone de contact centrale par un dénudage en fenêtre.
