Abstract

La présente invention concerne un raccord étanche au liquide (10) pouvant se monter sur un carter (26) de dispositif électrique ou mécanique et comportant une zone de prise (16) adjacente d'une de ses extrémités et dépassant extérieurement du carter (26). Plus particulièrement, le raccord (10) peut comporter un écrou de plombage (14) comportant une base (30) traversée d'un passage (36) selon l'axe longitudinal de la base et dont les cotes et la forme sont conçues pour recevoir de façon démontable la zone de prise (16) du raccord (10). L'écrou de plombage (14) comporte également un couvercle (32) s'articulant sur la base (30) de façon que le couvercle (32) soit mobile entre une position ouverte et une position fermée. En position ouverte, le couvercle dégage le passage (36) de la base (30) de façon suffisante pour permettre le passage d'un câble (33) traversant l'écrou de plombage (14) suivant une ligne sensiblement droite passant généralement parallèlement à l'axe longitudinal de la base (30). En position fermée, le couvercle (32) recouvre le passage (36) traversant la base (30) de façon que la couvercle (32) guide de manière lâche le câble pour qu'il s'y plie. Un mécanisme de retenue (52, 54, 56, 58) permet de maintenir le couvercle (32) en position fermée. Une pluralité de doigts (18) enserrant un fouloir (20) équipent la zone de prise (16) du raccord de manière à immobiliser une partie voisine du câble (33) de façon étanche et en éliminant les contraintes.
