Abstract

A conduit assembly has a visual inspection device. The visual inspection device is positioned within a connector housing. The device enables inspection of the connector to determine if proper connection between the housing and conduit has been achieved. The inspection device includes an annular member which, when in a vaulted position, exposes flags to indicate one position of the annular member to a substantially flat position concealing the flags to indicate a second position of the annular member.

Claims

1. A visual inspection device for quick connectors comprising:

annular means adapted for positioning about a conduit within a connector housing such that in a first position said annular member being substantially vaulted and in a second position said annular member being substantially flat; and

means for indicating the position of said annular means, said indicating means being visible to an observer when said annular member is in its first vaulted position and moving to a second position when said annular member is in its second position wherein said indicating means visually indicates to the observer that the conduit is securely coupled within the connector housing.

2. The visual inspection device according to claim 1 wherein said annular means includes at least one deformable portion for enabling said annular means to move between said first and second position.

3. The visual inspection device according to claim 1 wherein said annular means is formed from a resilient material.

4. The visual inspection device according to claim 1 wherein said indicating means includes at least one elongated member extending from said annular means and a flag associated with each elongated member for enabling visual inspection by an observer of the flag for determining the position of the annular means.

5. A quick connector assembly comprising:

a housing having a central bore therethrough;

a conduit adapted to be coupled with said housing;

means for retaining said conduit with said housing;

means for enabling visual inspection of the coupling of said conduit with said housing, said visual inspection means comprised of annular means adapted for positioning about said conduit, said annular means positioned within said housing such that in a first position, wherein said conduit is not retained in said housing, said annular means being substantially vaulted and in a second position, wherein said conduit is retained in said housing, said annular means being substantially flat; and

means for indicating the position of said annular means, said indicating means being visible to an observer when said annular member is in its first vaulted position and moving to a second position when said annular member is in its second position wherein said indicating means visually indicates to the observer that said conduit is retained in said connector housing.

6. The visual inspection device according to claim 5 wherein said annular means includes at least one deformable portion for enabling said annular means to move between said first and second position.

7. The visual inspection device according to claim 5 wherein said annular means is formed from a resilient material.

8. The visual inspection device according to claim 5 wherein said indicating means includes at least one elongated member extending from said annular means and a flag associated with each elongated member for enabling visual inspection by an observer of the flag for determining the position of the annular means.

9. A visual inspection device for quick connectors comprising:

an annular element having at least one deflectable portion and one rigid portion, said at least one deflectable portion continuous with and extending from said at least one rigid portion forming said annular element such that said annular element is vaulted in a relaxed position and said annular element is adapted to become substantially flat in an activated position; and

means for indicating the position of said annular element, said indicating means being visible to an observer when said annular member is in its first vaulted position and moving to a second position when said annular member is in its second position wherein said indicating means visually indicates to the observer that the conduit is securely coupled with the connector housing.

10. The visual inspection device for quick connectors according to claim 9 wherein said annular element includes a pair of resilient arcuate legs enabling movement between said first and second position.

11. The visual inspection device for quick connectors according to claim 9 wherein said annular element includes a pair of flat rigid members having said pair of arcuate legs extending therefrom.

12. The visual inspection device for quick connectors according to claim 11 wherein said indicating means includes a pair of elongated members extending from said flat members substantially perpendicular thereto and a flag on each of said elongated members for providing visual inspection of the position of said annular element.
