Abstract

A splice closure and fiber organizer device (10) comprises a substantially elongate body 5 member (12), closure member (16) and a foldable organizer tray (14) for accommodating at least one fiber splice and/or length(s) of excess fiber. The organizer tray which includes a plurality of fold lines (21) provided by respective living hinges is capable of being wrapped around part of the bodymember, into a generally cylindrical or part cylindrical shape, to close or partially close the closure. The fold lines enable the organizer tray to be folded into an extra 10 dimension, from a flat planar structure into a generally cylindrical or part cylindrical shape. This enables the closure to be more compact without compromising the bend control radius characteristics of the organizer tray. By restricting the minimum bend radius of the organizer to that of the fiber to be used bend control of installed fiber can be readily achieved. The device is particularly suitable for use in FTTX applications.

Claims

1. A splice closure and fibre organiser device comprising a substantially elongate body and a foldable organiser tray having holding members for accommodating at least one fibre splice and/or length(s) of excess fibre, the tray having a plurality of fold lines defining individual strips connected end to end and being capable of being wrapped around at least part of the body, into a generally cylindrical or part cylindrical shape, to close or partially close the closure, with the holding members on the inside of the closure.

2. A device as claimed in claim 1, wherein the organiser tray comprises a plurality of adjacent parallel strips hinged together along their respective adjoining edges.

3. A device as claimed in claim 2, wherein the adjoining edges of adjacent strips are joined together by respective living hinges.

4. A device as claimed in claim 2, wherein the adjoining edges of adjacent strips are joined together by respective mechanical hinges.

5. A device as claimed in claim 3, wherein the living hinges are co-moulded with the strips.

6. A device as claimed in claim 5, wherein the living hinge has a thickness of between 0.2 and 0.5 mm.

7. A device as claimed in claim 6, wherein the living hinge has a thickness of between 0.3 and 0.4 mm.

8. A device as claimed in claim 1, wherein the organiser tray is pivotally connected to the body.

9. A device as claimed in claim 1, wherein the organiser tray is closed against the body when the tray is wrapped around the body.

10. A device as claimed in claim 1, wherein the body comprises at least one cable termination retention means for securing incoming/outgoing cables with respect to the body.

11. A device as claimed in claim 10, wherein the organiser tray is capable of being wrapped around part of the body on one side thereof and the retention means is/are located on the other side thereof.

12. A splice closure and organiser as claimed in claim 11, wherein the body is in the shape of a half cylinder and the organiser tray is pivotally connected along one of its sides to the half cylinder along an axial edge thereof.

13. A splice closure and organiser as claimed in claim 12, wherein the retention means is/are located on an outward facing surface of a substantially planar part of the half cylinder and the organiser is arranged to be wrapped around the non-planar part of the half cylinder to close that side of the body.

14. A splice closure and organiser as claimed in claim 13, further comprising a closure member and wherein the organiser is pivotally connected along the other of its sides to the closure member so that the closure member is capable of being brought into proximity with the body to close the other side of the body.

15. A splice closure and organiser as claimed in claim 14, wherein the closure member is in the shape of a half cylinder having a size substantially the same as the body such that when brought together the two half cylinders define co-operating halves of a cylindrical closure.

16. A splice and closure organiser as claimed in claim 15, wherein the interior of the half cylindrical closure member includes at least one guide for guiding incoming and/or outgoing cables within the closure.

17. A fiber closure, comprising:

a substantially elongate body; and

a foldable organizer tray for accommodating at least one fiber, the tray having a plurality of fold lines defining individual strips connected end to end and being capable of being wrapped around at least part of the body to at least partially close the closure, wherein the foldable organizer tray is foldable into a generally cylindrical or part cylindrical shape.

18. A device as claimed in claim 17, wherein the organiser tray comprises a plurality of adjacent parallel strips hinged together along their respective adjoining edges.

19. A device as claimed in claim 17, wherein the organiser tray is pivotally connected to the body.

20. A device as claimed in claim 17, wherein the body comprises at least one cable termination retention means for securing incoming/outgoing cables with respect to the body.

21. A splice closure and fibre organiser device comprising a substantially elongate body and a foldable organiser tray for accommodating at least one fibre splice and/or length(s) of excess fibre, the tray having a plurality of fold lines defining individual strips connected end to end, wherein the body comprises at least one cable termination retention means for securing incoming/outgoing cables with respect to the body and the organiser tray being capable of being wrapped around part of the body on one side thereof into a generally cylindrical or part cylindrical shape, to close or partially close the closure, and the retention means being located on the other side thereof.

22. A device as claimed in claim 21, wherein the organiser tray comprises a plurality of adjacent parallel strips hinged together along their respective adjoining edges.

23. A device as claimed in claim 22, wherein the adjoining edges of adjacent strips are joined together by respective living hinges.

24. A device as claimed in claim 23, wherein the living hinges are co-moulded with the strips.

25. A device as claimed in claim 21, wherein the organiser tray is pivotally connected to the body.

26. A device as claimed in claim 21, wherein the organiser tray is closed against the body when the tray is wrapped around the body.

27. A splice closure and organiser as claimed in claim 21, wherein the body is in the shape of a half cylinder and the organiser tray is pivotally connected along one of its sides to the half cylinder along an axial edge thereof.

28. A splice closure and organiser as claimed in claim 21, further comprising a closure member pivotally connected to the organiser tray so that the closure member is capable of being brought into proximity with the body to close the other side of the body.

29. A splice closure and organiser as claimed in claim 28 wherein the closure member and the body are in the shape of half cylinders such that when brought together the two half cylinders define co-operating halves of a cylindrical closure.

30. A splice and closure organiser as claimed in claim 29, wherein the interior of the half cylindrical closure member includes at least one guide for guiding incoming and/or outgoing cables within the closure.

31. A splice closure and fibre organiser device comprising:

a substantially elongate body;

a foldable organiser tray for accommodating at least one fibre splice and/or length(s) of excess fibre; and

a closure member;

wherein

the elongate body and the closure member are positioned at opposite ends of the foldable organizer tray, and the foldable organiser tray being capable of being wrapped around, and enclose, at least part of a first side of the elongate body, and the closure member being movable to overlie a second side of the elongate body forming a closed shape.

32. A device as claimed in claim 31, wherein the organiser tray comprises a plurality of adjacent parallel strips hinged together along their respective adjoining edges.

33. A device as claimed in claim 31, wherein the elongate body has at least one cable termination retention means for securing incoming/outgoing cables with respect to the body.
