Abstract

A tubing connector adapted to receive portions of a plurality of elongate substantially rigid tubes and to hold them in a defined angular relationship relative to each other. The connector has a body with a plurality of tube-receiving and holding apertures formed therein. Stop elements in the apertures spaced inwardly from the mouths of the apertures limit the extent to which end portions of tubes may be inserted longitudinally into the body.

Claims

1. A tubing connector adapted to receive end portions of at least three elongate substantially rigid tubes and to hold them in defined angular relationship relative to each other, the connector comprising:

a body having a central portion and protrusions that extend outwardly from said central portion, said central portion and protrusions defining a plurality of tube-receiving and holding apertures formed therein with each aperture having a tube-receiving mouth offset from other apertures in the body through which a tube may be inserted into an aperture in said body, said body comprising a pair of laterally spaced side members which define side walls for apertures in said protrusions, and an aperture in the central portion extends between said spaced side members with said tube-receiving and holding apertures occupying a common plane, and

stop elements in said apertures in the protrusions spaced inwardly of the body from the mouth of its associated aperture to limit the extent to which an end portion of a tube may be inserted longitudinally into said body.

2. The connector of claim 1, wherein a stop member comprises an element secured at a selected location spaced inwardly on the body from the aperture mouth and extending between said side members.

3. The connector of claim 1, wherein each of said plural apertures has a central axis which is angularly disposed relative to the central axes of the other apertures.

4. The connector of claim 1, wherein one of said stop elements in a protrusion is positioned in an aperture in said protrusion to prevent a portion of a tube inserted in said aperture from projecting into the aperture in the central portion.

5. The connector of claim 4, wherein said one stop element comprises a wall extending between said side members and positioned between adjacent apertures to engage and limit insertion of a tube.

6. The connector of claim 1, wherein said body is monolithic and an aperture comprises a tunnel-like openings extending inwardly of the body from its tube-receiving mouth.

7. The connector of claim 1, wherein an aperture has a polygonal cross section.

8. The connector of claim 1, wherein the aperture in the central portion is disposed between the apertures in said protrusions.

9. The connector of claim 1, wherein the aperture in the central portion has a mouth formed in one of said side members and said aperture in said central portion is disposed between the apertures in said protrusions.

15. The connector of claim 8, which further comprises a gusset extending between at least two of said protrusions.

16. The connector of claim 15, wherein a protrusion has a pair of sidewalls disposed in spaced-apart planes and said gusset is disposed intermediate said planes.

17. The connector of claim 16, wherein said gusset is disposed closer to one of said planes than the other.

10. A tubing connector adapted to receive end portions of at least three elongate substantially rigid tubes and to hold them in defined angular relationship relative to each other, the connector comprising:

a body having a central portion and protrusions that extend outwardly from said central portion, said central portion and protrusions defining a plurality of tube-receiving and holding apertures formed therein with each aperture having a tube-receiving mouth offset from other apertures in the body through which a tube may be inserted into an aperture in said body, said body comprising a pair of laterally spaced side members which define side walls for apertures in said protrusions, and an aperture in the central portion extends between said spaced side members with said tube-receiving and holding apertures occupying a common plane, wherein each of said plural apertures has a central axis which is angularly disposed relative to the central axes of the other apertures, and

stop elements in said apertures spaced inwardly of the body from the mouth of its associated aperture to limit the extent to which an end portion of a tube may be inserted longitudinally into said body.

11. The connector of claim 10, wherein a stop member comprises an element secured at a selected location spaced inwardly on the body from the aperture mouth and extending between said side members.

12. The connector of claim 10, wherein one of said stop elements in a protrusion is positioned in an aperture in said protrusion to prevent a portion of a tube inserted in said aperture from projecting into the aperture in the central portion.

13. The connector of claim 12, wherein said one stop element comprises a wall extending between said side members and positioned between adjacent apertures to engage and limit insertion of a tube.

14. The connector of claim 10, wherein said body is monolithic and an aperture comprises a tunnel-like opening extending inwardly of the body from its tube-receiving mouth.

18. The connector of claim 10, wherein an aperture has a polygonal cross section.

19. The connector of claim 10, wherein the aperture in the central portion is disposed between the apertures in said protrusions.

20. The connector of claim 10, wherein the aperture in the central portion has a mouth formed in one of said side members and said aperture in said central portion is disposed between the apertures in said protrusions.
