Abstract

A sealing system for a telecommunication closure includes an endcap having a plurality of slotted areas defined therein; and a plurality of sealing segment assemblies mounted to the endcap that when combined form a substantially continuous sealing perimeter around the endcap. Each sealing segment assembly is disposed in one of the plurality of slotted areas and includes an inner segment and an outer segment that when mated together are configured to seal at least one cable routed through a cable port opening.

Claims (36)

1. A sealing system for a telecommunication closure, comprising:

an endcap having a plurality of slotted areas defined therein, the plurality of slotted areas each defining a plurality of elongated notches; and

a plurality of sealing segment assemblies mounted to the endcap that when combined form a substantially continuous sealing perimeter around the endcap, wherein each sealing segment assembly is disposed in one of the plurality of slotted areas and comprises:

an inner segment and an outer segment that when mated together are configured to seal at least one cable routed through a cable port opening; and

mating elements disposed within the plurality elongated notches, wherein the plurality of elongate notches extend in a direction parallel to an axial direction of the cable port opening.

2. The sealing system of claim 1 , wherein the endcap comprises an endcap body having an outer endcap rim with an upwardly extending edge and an inner endcap step positioned above the outer endcap rim.

3. The sealing system of claim 1 , wherein each slotted area has a curved profile that includes a semi-circular section.

4. The sealing system of claim 1 , wherein plurality of elongated notches are positioned at intervals along the inner surface of each slotted area.

5. The sealing system of claim 4 , wherein the mating elements extend from an outer surface of the inner segment and the outer segment.

6. The sealing system of claim 1 , wherein the endcap comprises end faces and wherein a tang extends from at least one of the end faces.

7. The sealing system of claim 6 , wherein the tang is configured to align and connect the sealing segment assembly with the slotted area of the endcap.

8. A sealing segment assembly for a telecommunication closure, comprising:

an inner segment;

an outer segment configured to mate with the inner segment, wherein the inner segment comprises an upper segment portion, a lower segment portion, and an inner segment seal disposed between the upper segment portion and the lower segment portion; and wherein the outer segment comprises an upper segment element, and outer perimeter element, and an outer segment seal disposed between the upper segment element and the outer perimeter element, an inner surface of the outer segment and the inner segment defining a cable port opening when mated to one another; and

mating elements extending from an outer surface the inner segment and/or the outer segment.

9. The sealing segment assembly of claim 8 , wherein the upper segment portion comprises a plurality of protruding mating elements configured for insertion into the upper segment element, wherein the plurality of protruding mating elements extend in a direction parallel to an axial direction of the cable port opening.

10. The sealing segment assembly of claim 8 , wherein lower segment portion comprises a plurality of protruding mating elements configured for insertion into the outer perimeter element.

11. The sealing segment assembly of claim 8 , wherein the upper segment element has an arc shape.

12. The sealing segment assembly of claim 8 , wherein the outer perimeter element has an arc shape.

13. The sealing segment assembly of claim 8 , wherein the outer segment seal has an arc shape.

14. A telecommunication closure, comprising:

a cover assembly; and

a sealing system, comprising:

an endcap having a plurality of slotted areas defined therein, the plurality of slotted areas each defining a plurality of elongated notches; and

a plurality of sealing segment assemblies mounted to the endcap that when combined form a substantially continuous sealing perimeter around the endcap, wherein each sealing segment assembly is disposed in one of the plurality of slotted areas and comprises:

an inner segment and an outer segment that when mated together are configured to seal at least one cable routed through a cable port opening; and

mating elements disposed within the plurality elongated notches, wherein the plurality of elongate notches extend in a direction parallel to an axial direction of the cable port opening.

15. The telecommunication closure of claim 14 , wherein the cover assembly comprises a cover and a clamping ring coupled to the cover.

16. The telecommunication closure of claim 15 , wherein the cover is a dome-type cover.

17. The telecommunication closure of claim 15 , wherein the clamping ring is positionable over a portion of the cover and further comprises a clamping arm.

18. The telecommunication closure of claim 17 , wherein the clamping arm has an aperture defined therein.

19. The telecommunication closure of claim 18 , wherein the aperture is configured to receive a cover fastener.

20. A method of sealing a cable disposed in a telecommunication closure comprising:

positioning an inner segment into a slotted area of an endcap, the slotted area defining a plurality of elongated notches;

positioning an outer segment into the slotted area wherein the outer segment defines mating elements which are disposed within the plurality of elongated notches; and

coupling the outer segment and the inner segment together to form a cable port seal around one or more cables, wherein the plurality of elongate notches extend in a direction parallel to an axial direction of the cable port opening.
