Abstract

A fluid connection assembly including a connector body, and a retainer, including a first end removably connectable to the connector body, a second end, a first radially outward facing surface extending from the first end to the second end, a first radially inward facing surface extending from the first end to the second end, a first flange extending radially inward from the first end, and a second flange extending radially inward from the second end, wherein at least one of the first flange and the second flange includes a plurality of circumferentially separated sections.

Claims (75)

1 . A fluid connection assembly, comprising:

a connector body; and

a retainer, including:

a first end removably connectable to the connector body;

a second end;

a first radially outward facing surface extending from the first end to the second end;

a first radially inward facing surface extending from the first end to the second end;

a first section including a first projection extending radially outward from the first radially outward facing surface and a first hole extending radially outward from the first radially inward facing surface;

a second section displaceable with respect to the first section, the second section including a second projection extending radially outward from the first radially outward facing surface and a second hole extending radially outward from the first radially inward facing surface;

a first flange extending radially inward from the first end; and

a second flange extending radially inward from the second end;

wherein:

at least one of the first flange and the second flange comprises a plurality of circumferentially separated sections; and

the first projection and the second projection are operatively arranged to engage the second hole and the first hole, respectively, to lock the second section to the first section.

2 . The fluid connection assembly as recited in claim 1 , wherein the second section is removably connectable to the first section.

3 . The fluid connection assembly as recited in claim 1 , wherein the first section further comprises a third hole arranged immediately adjacent to the first projection.

4 . The fluid connection assembly as recited in claim 1 , wherein:

the first radially outward facing surface comprises a third section, the third section arranged on the first section;

the second section comprises a third flange extending radially from the first radially outward facing surface; and

in a locked state of the retainer the third flange overlaps the third section.

5 . The fluid connection assembly as recited in claim 4 , wherein in the locked state the third section is arranged parallel to the third flange.

6 . The fluid connection assembly as recited in claim 1 , wherein the retainer comprises a plurality of planar sections connected at obtuse angles.

7 . The fluid connection assembly as recited in claim 1 , wherein the connector body comprises:

a third end;

a fourth end;

a second radially inward facing surface forming a through-bore; and

a second radially outward facing surface including a groove, wherein the first flange is arranged to engage the groove to removably connect the retainer to the connector body.

8 . The fluid connection assembly as recited in claim 7 , further comprising a tube including a shoulder, wherein the tube is arranged to be fluidly connected to the connector body via the retainer.

9 . The fluid connection assembly as recited in claim 8 , wherein in a connected state, the shoulder is axially arranged between the second flange and the fourth end.

10 . The retainer as recited in claim 1 , wherein:

the first hole is a first through-hole extending from the radially inward facing surface to the radially outward facing surface; and

the second hole is a second through-hole extending from the radially inward facing surface to the radially outward facing surface.

11 . The retainer as recited in claim 10 , wherein:

the first projection is a hook; and

the hook is operatively arranged to engage the second through-hole to pivotably connect the first section with the second section.

12 . A fluid connection assembly, comprising:

a connector body, including:

a first end;

a second end;

a through-bore extending from the first end to the second end;

a first radially inward facing surface; and

a first radially outward facing surface including a groove; and a retainer, including:

a third end;

a fourth end;

a second radially outward facing surface extending from the third end to the fourth end;

a second radially inward facing surface extending from the third end to the fourth end;

a first section, including:

a first flange extending radially inward from the third end and operatively arranged to engage the groove to removably connect the retainer to the connector body;

a second flange extending radially inward from the fourth end;

a first circumferential end including a first protrusion proximate thereto and extending radially outward from the second radially outward facing surface; and

a second circumferential end arranged substantially diametrically opposed to the first circumferential end, the second circumferential end including a first radially extending hole proximate thereto;

wherein at least one of the first flange and the second flange comprises a plurality of sections separated by circumferential spaces, the circumferential spaces extending completely to the radially inward facing surface; and

a second section radially displaceable with respect to the first section.

13 . The fluid connection assembly as recited in claim 12 , wherein:

the second section comprises a second protrusion extending radially outward from the second radially outward facing surface and a second radially extending hole; and

the first protrusion and the second protrusion are operatively arranged to engage the second radially extending hole and the first radially extending hole, respectively, to lock the first section to the second section.

14 . The fluid connection assembly as recited in claim 13 , wherein:

the first section further comprises a first through-hole arranged immediately adjacent to the first protrusion; and

the second section further comprises a second through-hole arranged immediately adjacent the second protrusion.

15 . The fluid connection assembly as recited in claim 12 , wherein the retainer comprises a plurality of planar sections connected at obtuse angles.

16 . A retainer for a fluid connection assembly, the retainer comprising:

a first end;

a second end;

a radially outward facing surface extending from the first end to the second end;

a radially inward facing surface extending from the first end to the second end;

a first section including a first projection extending radially outward from the radially outward facing surface and a first hole extending radially outward from the radially inward facing surface;

a second section displaceable with respect to the first section, the second section including a second projection extending radially outward from the radially outward facing surface and a second hole extending radially outward from the radially inward facing surface;

a first flange extending radially inward from the first end, the first flange including a first plurality of circumferentially separated sections; and

a second flange extending radially inward from the second end, the second flange including a second plurality of circumferentially separated sections;

wherein the first projection and the second projection are operatively arranged to extend radially outward through the second hole and the first hole, respectively, to lock the second section to the first section.

17 . The retainer as recited in claim 16 , wherein:

the first hole is a first through-hole extending from the radially inward facing surface to the radially outward facing surface; and

the second hole is a second through-hole extending from the radially inward facing surface to the radially outward facing surface.

18 . The retainer as recited in claim 16 , wherein the retainer further comprises a plurality of planar sections forming the radially outward facing surface and the radially inward facing surface.

19 . The retainer as recited in claim 18 , wherein the plurality of sections are connected at obtuse angles.
