Patent

CA 2278343

A liquid-tight fitting (10), which is mountable on a housing (26) of an electrical or mechanical device and which includes a grasping portion (16) adjacent an end thereof projecting outwardly from the housing (26), is disclosed. More particularly, the fitting (10) may include a sealing nut (14) with a base (30) having a passageway (36) extending therethrough along a longitudinal axis of the base and being sized and shaped to removably receive the grasping portion (16) of the fitting (10). The sealing nut (14) also includes a cover (32) pivotally connected to the base (30) such that the cover (32) is movable between an open position, in which the cover exposes the passageway (36) of the base (30) to an extent sufficient to allow a cable (33) to be fed through the sealing nut (14) in a substantially straight line running generally parallel to the longitudinal axis of the base (30), and a closed position, in which the cover (32) overlies the passageway (36) in the base (30) such that the cover (32) loosely guides the cable to form a bend therein. A retaining mechanism (52, 54, 56, 58) is provided for retaining the cover (32) in its closed position. A plurality of fingers (18) embracing a gland (20) are provided on the grasping portion (16) of the fitting (10) so as to grasp an adjacent portion of the cable (33) in a liquid-tight and strain- relieving manner.

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.
