Patent

CA 2664140

A male coupling that is connectable to and separable from a female threaded coupling (e.g., a female threaded port) is provided. The female threaded coupling includes a sealing surface and a receiving portion sized to receive at least a portion of the male coupling, where the receiving portion has internal threads provided therein. The male coupling includes a body having a passageway extending therethrough and a locking member (e.g., ratcheting or non- ratcheting) disposed about the body and configured to move between locking and releasing positions. The locking member has a retaining formation configured to engage the internal threads of the female threaded coupling when the locking member is in its locking position. The male coupling also includes an axially movable sleeve disposed about the body and an annular seal disposed about the sleeve. After insertion of the male coupling into the female threaded coupling, the retaining formation of the locking member engages one or more of the internal threads in the female threaded coupling when the locking member is in its locking position. Upon movement of the sleeve towards the female threaded coupling, the annular seal is compressed against the sealing surface of the female threaded coupling.

La présente invention concerne un raccord mâle qui peut être relié à un raccord fileté femelle (par exemple, un port fileté femelle) et être séparé de ce dernier. Le raccord fileté femelle comprend une surface d'étanchéité et une partie de réception dimensionnée de manière à recevoir au moins une partie du raccord mâle, la partie de réception contenant des filetages internes. Le raccord mâle comprend un corps, à travers lequel s'étend un passage, et un élément de verrouillage (par exemple d'encliquetage ou de non-encliquetage) disposé autour du corps et conçu pour se déplacer entre des positions de verrouillage et de libération. L'élément de verrouillage possède une structure de retenue conçue pour venir en prise avec les filetages internes du raccord fileté femelle lorsque l'élément de verrouillage se trouve en position de verrouillage. Le raccord mâle possède également un manchon axialement mobile disposé autour du corps et un joint annulaire disposé autour du manchon. Une fois que le raccord mâle a été introduit dans le raccord fileté femelle, la structure de retenue de l'élément de verrouillage vient en prise avec un ou plusieurs des filetages internes du raccord fileté femelle lorsque l'élément de verrouillage se trouve en position de verrouillage. Le déplacement du manchon vers le raccord fileté femelle a pour effet de comprimer le joint annulaire contre la surface d'étanchéité du raccord fileté femelle.
