Breakaway thread-lock quick connect/disconnect coupling

摘要

A female coupler for a breakaway thread-lock quick disconnect coupling having a retainer wire positioned interiorly of an outer housing and a coupler support portion that prevents contamination of the retainer wire and a capture space formed by grooves in the outer housing and an inner housing, which may prevent degradation of performance and/or decrease the chances that the retainer wire is dislodged.

主权项

1. A female coupler for a quick connect/disconnect coupling, the female coupler including:
a retainer wire; an inner housing having a radially outwardly opening groove and a nipple portion for sealing to an inner diameter surface of a corresponding male coupler; an outer housing having a radially inwardly opening groove aligned with the radially outwardly opening groove, wherein the grooves form a capture space for receiving the retainer wire, the retainer wire having a dimension greater than a depth of each groove so that when the retainer wire is inserted into the capture space, the wire axially interferes with sidewalls of the grooves to restrict relative axial movement of the inner and outer housings; and a female coupler support having a proximal end rotatably supported on a radially outer surface of the inner or outer housing and a distal end being internally threaded for threaded receipt of an externally threaded portion of the corresponding male coupler.
