CA 2379808

A two-part connector structure (22, 32) includes a male connector part (32) and a female connector part (22) which are mutually engageable to open fluid communication between the connector parts (22, 32). For example, the connector parts (22, 32) may be used to establish fluid communication between a container (12) and a conduit (14). The connector parts (22, 32) are disengageable from one another to discontinue fluid communication between them, and also to close communication between ambient and each of the container and the conduit. The male connector part (32) includes a mounting structure (32a) for supporting on the female connector part (22), and also includes a guide structure (44) effective to guide a male probe portion (36) of the male connector part (32) into engagement with the female connector part (22). A handnut (34) of the male connector part (32), and is effective upon manual rotation to cause axial relative movement of the male probe portion (36) into or out of engagement with the female connector part (32). This invention provides a connector structure (22, 32) with considerably lowered manual engagement and disengagement forces, along with increased convenience and ease of use.

Cette invention se rapporte à une structure de raccords en deux pièces (22, 32), qui comprend un raccord mâle (32) et un raccord femelle? ¿(22), se vissant l'un dans l'autre pour permettre le passage du fluide entre les deux raccords (22, 32). Ces raccords (22, 32) peuvent par exemple servir à établir une communication fluidique entre un récipient (12) et un conduit (14). Les raccords (22, 32) sont dévissables l'un de l'autre, pour interrompre le passage du fluide entre eux et également pour fermer toute communication entre l'atmosphère et chacun des deux dispositifs que sont le récipient et le conduit. Le raccord mâle (32) comporte une structure de montage (32a) servant de support au raccord femelle (22) et il contient également une structure guide (44) servant à guider le vissage de la partie de sonde mâle (36) du raccord mâle (32) dans le raccord femelle (22). Un écrou à main (34) du raccord mâle (32) entraîne, par rotation manuelle, un mouvement relatif axial de la partie de sonde mâle (36) permettant son vissage et son dévissage par rapport au raccord femelle (32). Cette invention crée ainsi une structure de raccords (22, 32) se caractérisant par des forces de vissage et de dévissage manuels considérablement réduites, ainsi que par une utilisation plus pratique et plus aisée.
