Self-unlocking fluid-tight connector

摘要

A connector is used to connect a conduit to a threaded orifice of a fluidic component, such as a component of an apparatus for chromatography. The connector includes a flexible fitting, a deformable fitting, and a compression fitting. The flexible fitting fixes the position of the conduit with respect to the threaded orifice. The deformable fitting provides a fluid-tight seal between the fluidic conduit and the threaded orifice. The compression fitting includes an external-thread portion for attachment to the orifice, to urge the flexible fitting toward an outer surface of the fluidic conduit, and to urge the deformable fitting toward both the outer surface and the orifice, a cam portion in mechanical communication with the flexible fitting via a through-hole in the external thread portion, and a graspable portion in rotatable communication with the cam portion.

主权项

1. A device for connecting a fluidic conduit to a threaded orifice of a fluidic component, comprising:
a flexible fitting for substantially fixing a position of the fluidic conduit with respect to the threaded orifice; a deformable fitting for providing a substantially fluid-tight seal between the fluidic conduit and the threaded orifice; and a compression fitting comprising
an external-thread portion having a thread and a non-round slot, wherein the thread mates with the threaded orifice and the flexible fitting is wedged between the external-thread portion and the fluidic conduit,a screw-driven cam portion having a non-round extension disposed in the non-round slot of the external-thread portion and an externally threaded rear extension,a graspable portion having a threaded internal surface, wherein the externally threaded rear extension of the screw-driven cam mates with the graspable portion to secure or loosen the flexible fitting, anda retainer portion attached to the graspable portion to retain the screw-driven cam portion in the graspable portion.
