Abstract

A threaded retainer including a body having a through-bore therein, a first screw thread operatively arranged on an outer surface of the body, wherein, the first screw thread is arranged to secure the threaded retainer to a fluid connector having a second screw thread, the first screw thread corresponding with the second screw thread, a first shoulder arranged on the body, wherein the first shoulder is arranged to abut against a second shoulder of the fluid connector, and an axial gap between the fluid connector and the threaded retainer, wherein the axial gap is formed when the fluid connector is secured to the threaded retainer.

First claim

What is claimed is:

1. A threaded retainer, comprising:
a body, said body including a distal end and a first through-bore;
a first screw thread operatively arranged on an outer surface of said body, wherein, said first screw thread is arranged to secure said threaded retainer to a fluid connector including a second screw thread, said first screw thread corresponding with said second screw thread;
a tapered surface extending radially outward from said distal end to said first screw thread;
a first shoulder arranged on said body, wherein said first shoulder is arranged to abut against a second shoulder of said fluid connector; and,
an axial gap between said distal end and a third shoulder of said fluid connector, wherein said axial gap is formed when said fluid connector is secured to said threaded retainer.

2. The threaded retainer as recited in claim 1 , wherein said fluid connector comprises a second through-bore extending linearly completely therethrough and forming an inner surface, said third shoulder being arranged in the second through-bore.

3. The threaded retainer as recited in claim 2 , wherein said second screw thread is operatively arranged on said inner surface of said fluid connector.

4. The threaded retainer as recited in claim 2 , wherein said first shoulder and said second shoulder abut within said second through-bore.

5. The threaded retainer as recited in claim 2 , wherein said first shoulder and said second shoulder abut outside of said second through-bore.

6. The threaded retainer as recited in claim 2 , wherein said first screw thread and said second screw thread form the axial gap within said second through-bore when secured together.

7. The threaded retainer as recited in claim 6 , further comprising a tubular connector including a tube barb extending radially outward.

8. The threaded retainer as recited in claim 7 , wherein said tube barb is operatively arranged within said axial gap.

9. The threaded retainer as recited in claim 8 , wherein said tubular connector can rotate relative to said threaded retainer and said fluid connector.

10. A fluid connector assembly, comprising:
a threaded retainer comprising:
a first body, said body including a first distal end and a first through-bore, the first distal end including a distal end surface;
a first screw thread operatively arranged on an outer surface of said first body; and,
a first shoulder including a first shoulder surface arranged on said outer surface;
a first tapered surface extending radially outward from said first distal end to said first screw thread; and,

a fluid connector comprising:
a second body, said second body including a second through-bore extending linearly and completely therethrough, forming an inner surface;
a second screw thread formed on said inner surface;
a second shoulder including a second shoulder surface arranged at a second distal end on said second through-bore;
a second tapered surface extending radially inward from said second distal end to said second screw thread; and,
a third shoulder including a third shoulder surface arranged in said second through-bore, the third shoulder surface being parallel to the distal end surface, wherein an axial gap is formed between said first distal end and said third shoulder when said threaded retainer and said fluid connector are secured together.

11. The fluid connector assembly as recited in claim 10 , wherein said first screw thread is arranged to secure said threaded retainer to said fluid connector via said second screw thread, said first screw thread corresponding with said second screw thread.

12. The fluid connector assembly as recited in claim 10 , wherein said first shoulder surface and said second shoulder surface are parallel surfaces.

13. The fluid connector assembly as recited in claim 10 , further comprising a tubular connector including a tube barb extending radially outward.

14. The fluid connector assembly as recited in claim 13 , wherein said tube barb is operatively arranged within said axial gap.

15. The fluid connector assembly as recited in claim 14 , wherein said tubular connector can rotate relative to said fluid connector and said threaded retainer.

16. The fluid connector assembly as recited in claim 10 , wherein said first shoulder abuts against said second shoulder when said threaded retainer is secured to said fluid connector.

17. A fluid connector assembly, comprising:
a threaded retainer comprising:
a first body, said body including a first distal end, a first through-bore, and a first counter-bore connected to and extending axially from said first distal end;
a first screw thread operatively arranged on an outer surface of said first body; and,
a first shoulder arranged on said outer surface;

a fluid connector comprising:
a second body, said second body including:
a second distal end, a second through-bore, and a second counter-bore connected to and extending axially from said second distal end, the second counter-bore forming an inner surface;

a second screw thread formed on said inner surface of said second counter-bore;
a second shoulder arranged to abut against said first shoulder of said threaded retainer; and,
a third shoulder extending between said second through-bore and said second counter-bore, wherein, an axial gap is formed between said first distal end and said third shoulder when said threaded retainer and said fluid connector are secured together; and,

a tubular connector including a tube barb extending radially outward, said tube barb arranged within said axial gap, wherein said first counter-bore is arranged radially outward of said tube barb.

18. The threaded retainer as recited in claim 17 , wherein said second shoulder of said fluid connector is arranged on said inner surface of said second counter-bore.

19. The threaded retainer as recited in claim 17 , wherein said second shoulder of said fluid connector is an axially facing shoulder surface of said fluid connector, said surface arranged on the second distal end of said fluid connector.

20. The threaded retainer as recited in claim 17 , wherein the second through-bore extends linearly and completely through the second body.
