Abstract

The present disclosure relates to a sealed closure having modular components, enhanced cable sealing, modular connection interfaces, enhanced cable anchoring and enhanced fiber management.

First claim

What is claimed is:

1. A telecommunications device comprising:
a re-enterable enclosure including a cable access end;
an insert unit that can be loaded into the re-enterable enclosure as a unit, the insert unit having a first side and a second side, the insert unit including:
a first sealant containment arrangement that is positioned adjacent the cable access end of the enclosure when the insert unit is positioned within the enclosure, the first sealant containment region including a first cable routing region for routing cables through the cable access end of the enclosure to the first side of the insert unit, and a second sealant containment region including a second cable routing region for routing cables through the cable access end of the enclosure to the second side of the insert unit;
a first cable anchoring location at the first side of the insert unit;
a second cable anchoring location at the second side of the insert unit;
a fiber patching region at the first side of the insert unit, the fiber patching region including either optical splicing locations or demateable optical connection locations;
a fiber loop-storage region at the second side of the insert unit; and
a fiber splicing region layered between the first and second sides of the insert unit.

2. The telecommunications device of claim 1 , wherein the fiber loop-storage region is provided on a pivotal tray.

3. The telecommunications device of claim 1 , wherein the fiber patching region includes the demateable optical connection locations.

4. The telecommunications device of claim 1 , wherein the insert unit includes a sealant containment and cable anchoring frame which includes the first sealant containment arrangement, the first cable anchoring location, and the second cable anchoring location.

5. The telecommunications device of claim 4 , further comprising an intermediate tray attached to one end of the sealant containment and cable anchoring frame, the intermediate tray including a first side that faces toward the first side of the insert unit and a second side that faces toward the second side of the insert unit.

6. The telecommunications device of claim 5 , further comprising a fiber optic adapter mounting panel that attaches to the first side of the intermediate tray.

7. The telecommunications device of claim 6 , wherein the fiber optic adapter mounting panel attaches to the first side of the intermediate tray by a snap-fit connection.

8. The telecommunications device of claim 7 , further comprising a cover that covers the first side of the intermediate tray.

9. The telecommunications device of claim 8 , wherein the cover is removable.

10. The telecommunications device of claim 8 , wherein the adapter mounting panel has a first side that faces toward the first cable anchoring location and a second side that faces away from the first cable anchoring location, wherein the cover includes a first portion that covers a first portion of the intermediate tray positioned at the first side of the adapter mounting panel and a second portion that covers a second portion of the intermediate tray positioned at the second side of the adapter mounting panel, the first portion of the cover aligning with a bottom of the adapter mounting panel and the second portion of the cover extending to a top of the adapter mounting panel.

11. The telecommunications device of claim 10 , wherein the second portion of the cover is a dome portion.

12. The telecommunications device of claim 5 , further comprising a splice tray mounted at the second side of the intermediate tray.

13. The telecommunications device of claim 12 , further comprising a pivotal tray at which the fiber loop-storage storage region of the insert unit is provided, the pivotal tray being movable relative to the sealant containment and cable anchoring frame between a first position wherein the pivotal tray covers a side of the splice tray and a second position wherein the side of the splice tray is accessible from the second side of the insert unit.

14. The telecommunications device of claim 13 , wherein the pivotal tray is pivotally movable via a pivot interlock including a detent pivot arrangement and a guide pivot arrangement.

15. The telecommunications device of claim 1 , further comprising a component attached to the insert unit by a mechanical interface having a stop that is positioned in a stop receptacle of a flexible cantilever latch prior to sliding the mechanical interface into a latched position.

16. The telecommunications device of claim 1 , wherein the first sealant containment arrangement includes a volume compensation plate including tapered projections.

17. The telecommunication device of claim 1 , further comprising a cable anchor secured to the first or second cable anchoring location by a snap-fit connection.

18. The telecommunications device of claim 1 , further comprising a cable anchor attachable to the first or second cable anchoring location, the cable anchor comprising:
an anchor component having a cable strength member clamp at a first end, a retention tab at an opposite second end, and a cable clamp mounting bracket between the first and second ends, the cable clamp mounting bracket including first and second fingers separated by a gap; and
a strap-style cable clamp mounted at the cable clamp mounting bracket.

19. The telecommunications device of claim 1 , further comprising a cable anchoring system usable at the first or second cable anchoring location, the cable anchoring system comprising:
a section of hook tape including a tape layer and a plurality of mini-hooks integrated with a hook side of the tape layer; and
a strap-style cable clamp for compressing strength members of a fiber optic cable against the hook side of the tape layer.

20. The telecommunications device of claim 1 , further comprising cable sealing gel contained by the first sealant containment arrangement, wherein the first sealant containment arrangement further comprises a volume compensation plate positioned at an outer boundary of the cable sealing gel, the volume compensation plate defining a plurality of gel receiving openings into which the cable sealing gel flows when the cable sealing gel is pressurized while cabling is present at the first or second cable routing region, wherein at least some of the cable sealing gel extrudes through the gel receiving openings into a region defined between the enclosure and the volume compensation plate.

21. The telecommunications device of claim 1 , further comprising cable sealing gel contained by the first sealant containment arrangement, wherein the first sealant containment arrangement further comprises a spring plate positioned at an outer boundary of the cable sealing gel that flexes into an open region defined between the enclosure and the spring plate when the cable sealing gel is pressurized while cabling is present at the first or second cable routing region.

22. A telecommunications enclosure comprising:
a housing that is elongate along a major axis of the housing, the major axis extending along a length of the housing between first and second opposite ends, the housing including a base and a cover that cooperate to define an interior of the housing, the cover being pivotally connected to the base and being pivotally movable relative to the base between an open position and a closed position, the cover defining a front of the housing and the base defining a rear of the housing;
a sealing arrangement for sealing
