Abstract

A cartridge for a fluid connector including a connector body having a bore and a flange, and a tube end form, the cartridge including a first end, a second end, a through-bore, a first radially outward facing surface including at least one aperture extending radially inward to the through-bore, and a retaining clip including at least one protrusion operatively arranged to extend into the through-bore.

First claim

What is claimed is:

1. A cartridge for a fluid connector including a connector body having a bore and a flange, and a tube end form, the cartridge comprising:
a first end;
a second end;
a first radially outward facing surface arranged between the first end and the second end;
a through-bore;
a plurality of projections extending in a first axial direction from and circumferentially spaced about the second end, the plurality of projections forming a second radially outward facing surface including at least one aperture extending radially inward to the through-bore; and
a retaining clip including at least one protrusion operatively arranged to extend into the through-bore;
further comprising a radially inward facing surface operatively arranged to engage a shoulder of the tube endform, wherein the radially inward facing surface is frusto-conical.

2. The cartridge as recited in claim 1 , wherein the retaining clip is arranged on the second radially outward facing surface and the at least one protrusion extends through the at least one aperture.

3. The cartridge as recited in claim 1 , further comprising a third radially outward facing surface extending from the first radially outward facing surface to the first end, the third radially outward facing surface being frusto-conical and decreasing in diameter in a second axial direction, opposite the first axial direction.

4. The cartridge as recited in claim 1 , further comprising a washer removably engaged with the plurality of projections, wherein the retaining clip is arranged axially between the second end and the washer.

5. The cartridge as recited in claim 4 , wherein:
the first radially outward facing surface includes a first diameter;
the second radially outward facing surface includes a second diameter; and
the first diameter is greater than the second diameter.

6. The cartridge as recited in claim 1 , wherein the cartridge is operatively arranged to be secured in the bore by crimping the flange radially inward.

7. A fluid connector, comprising:
a connector body, including:
a first end;
a second end;
a first through-bore;
a first groove arranged circumferentially within the first through-bore;
a seal arranged within the first groove; and
a flange; and

a cartridge arranged completely within the connector body, including:
a third end;
a fourth end;
a second through-bore;
a first radially outward facing surface including at least one aperture extending radially inward to the second through-bore; and
a retaining clip operatively arranged on the first radially outward facing surface, the retaining clip including at least one protrusion extending through the at least one aperture and into the second through-bore.

8. The fluid connector as recited in claim 7 , wherein the flange comprises a first section and a second section, the second section is crimped radially inward and engages the fourth end to secure the cartridge in the first through-bore and form a connected state.

9. The fluid connector as recited in claim 8 , wherein:
in an unconnected state, the second section is substantially aligned with the first section; and
in the connected state, the second section is substantially perpendicular to the first section and is engaged with the fourth end.

10. The fluid connector as recited in claim 7 , wherein the first radially outward facing surface comprises a second groove and the at least one aperture is arranged in the second groove.

11. The fluid connector as recited in claim 7 , wherein the cartridge further comprises a radially inward facing surface operatively arranged to engage a shoulder of a tube end form.

12. The fluid connector as recited in claim 11 , wherein the radially inward facing surface is frusto-conical.

13. The fluid connector as recited in claim 11 , wherein the retaining clip is operatively arranged to secure the tube end form to the connector body.

14. The fluid connector as recited in claim 8 , wherein in the connected state, the third end encloses the seal within the first groove.

15. A fluid connector, comprising:
a connector body, including:
a first through-bore;
a first groove arranged circumferentially within the first through-bore;
a seal arranged within the first groove; and
a malleable flange; and

a cartridge operatively arranged to be secured in the first through-bore, including:
a first end;
a second end;
a second through-bore;
a first radially outward facing surface including at least one aperture extending radially inward to the second through-bore; and
a retaining clip operatively arranged to extend through the at least one aperture and into the second through-bore;

wherein the malleable flange is crimped radially inward over the second end to secure the cartridge within the connector body.

16. The fluid connector as recited in claim 15 , wherein the malleable flange comprises a first section and a second section, the second section is operatively arranged to be crimped radially inward to secure the cartridge in the first through-bore and form a connected state.

17. The fluid connector as recited in claim 16 , wherein:
in an unconnected state, the second section is not engaged with the second end; and
in the connected state, the second section is engaged with the second end.

18. The fluid connector as recited in claim 7 , wherein the cartridge is arranged axially between and spaced apart from the first end and the second end.
