Abstract
A quick connector assembly connects to and establishes fluid communication with a male end port. The quick connector assembly includes a female component and an internal clip carried by the female component. The quick connector assembly receives the male end port in a single predetermined rotational orientation for retaining the male end port and the quick connector assembly non-rotatable receives the male end port.
Claims12
A fluid transfer arrangement comprising:
- a male end port including a tubular portion, the male end port comprising:
- a rib extending circumferentially on a radially outer surface of the male end port, the rib extending only partially about a radially outer circumference of the male end port, leaving a gap between a first and a second circumferential ends of the rib, the rib comprising:
- a first portion of the rib that extends continuously from the first circumferential end of the rib to the second circumferential end of the rib, leaving the gap open therebetween;
- a second portion of the rib arranged against and connected to the first portion, the second portion having:
- a first blocking member of the second portion extending from the first circumferential end of the rib and continuing circumferentially on the first portion to terminate at a first blocking surface;
- a second blocking member of the second portion extending from the second circumferential end of the rib and continuing circumferentially on the first portion to terminate at a second blocking surface;
- wherein an engagement area is formed by circumferential open space in the second portion of the rib between and circumferentially delimited by the first blocking surface and the second blocking surface;
- wherein the first portion of the rib has a first width in an axial direction;
- and
- wherein the second portion of the rib has a second width that is greater than the first width;
- and
- a quick connector assembly for connecting to and establishing fluid communication with the male end port, the quick connector assembly including:
- a female component;
- and
- an internal clip carried by the female component,
- wherein the quick connector assembly receives the male end port in a single predetermined rotational orientation for retaining the male end port and the quick connector assembly non-rotatably receives the male end port.

- and
- a quick connector assembly for connecting to and establishing fluid communication with the male end port, the quick connector assembly including:
- a female component;
- and
- an internal clip carried by the female component,
- the internal clip including
- a generally cylindrical portion and
- a cantilevered retention portion,
- the cantilevered retention portion axially spaced from the cylindrical portion by a gap having an axial gap width,
- wherein the rib of the male end port has a first axial rib width less than the axial gap width and a second axial rib width greater than the axial gap width such that the male end port is positioned in a single predetermined rotational orientation for engagement with the quick connector assembly.
