Abstract

A butt closure base includes a base housing defining a plurality of cavities. A first gel is disposed in each of the plurality of cavities. The butt closure base further includes a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities. Each of the plurality of wedge assemblies includes an outer cover, and a second gel. The butt closure base further includes a plurality of cable entry passages, each of the plurality of cable entry passages defined between one of the plurality of cavities and one of the plurality of wedge assemblies. The butt closure base further includes a plurality of bushings, each of the plurality of bushings disposed in one of the plurality of cable entry passages.

First claim

What is claimed is:

1 . A butt closure base, comprising:
a base housing extending along a longitudinal axis between a first outer surface and a second outer surface, the base housing defining a plurality of cavities between the first and second outer surfaces, the plurality of cavities aligned in an annular array, wherein a first gel is disposed in each of the plurality of cavities; a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities, each of the plurality of wedge assemblies comprising an outer cover and a second gel; a plurality of cable entry passages, each of the plurality of cable entry passages defined between one of the plurality of cavities and one of the plurality of wedge assemblies; and a plurality of bushings, each of the plurality of bushings disposed in one of the plurality of cable entry passages.

2 . The butt closure base of claim 1 , further comprising a plurality of barrier members, each of the plurality of barrier members disposed between one of the plurality of cavities and one of the plurality of wedge assemblies and in contact with the first gel disposed in the respective cavity and the second gel of the respective wedge assembly,
wherein each of the plurality of bushings contacts one of the plurality of barrier members.

3 . The butt closure base of claim 2 , wherein each of the plurality of barrier members comprises a band and a plurality of fingers extending from the band.

4 . The butt closure base of claim 3 , wherein each of the plurality of bushings comprises a retention lip which contacts tip ends of the fingers of the associated barrier member.

5 . The butt closure base of claim 2 , wherein each of the plurality of barrier members is conical.

6 . The butt closure base of claim 2 , wherein each of the plurality of barrier members is formed from a polypropylene.

7 . The butt closure base of claim 1 , wherein each of the plurality of bushings is formed from a thermoplastic elastomer, rubber, or polyethylene.

8 . The butt closure base of claim 1 , wherein each of the plurality of bushings comprises a conical body defining a central passage, wherein a slot is defined through the conical body and in communication with the central passage.

9 . The butt closure base of claim 8 , wherein the conical body further defines an exterior tie-wrap channel.

10 . The butt closure base of claim 8 , wherein the conical body further comprises a tip, the tip defining a retention lip.

11 . The butt closure base of claim 1 , wherein each of the plurality of cavities is defined between surfaces of opposing sidewalls, and wherein the surfaces extend substantially parallel to each other.

12 . The butt closure base of claim 1 , wherein each of the plurality of wedge assemblies further comprises a main pressure plate in contact with the second gel, the main pressure plate movable along the longitudinal axis to apply pressure to the second gel;

13 . The butt closure base of claim 1 , wherein each of the plurality of wedge assemblies further comprises an outer flange extending from the outer cover, and wherein each of the plurality of wedge assemblies further comprises a plurality of apertures defined at an intersection between the outer flange and the outer cover, and wherein the second gel extends through each of the plurality of apertures.

14 . The butt closure base of claim 1 , further comprising a plurality of cable collar assemblies, each of the plurality of cable collar assemblies insertable into one of the plurality of cavities, each of the plurality of cable collar assemblies comprising a cable clamp and a frame, the frame defining a passage and a slot.

15 . A butt closure base, comprising:
a base housing extending along a longitudinal axis between a first outer surface and a second outer surface, the base housing defining a plurality of cavities between the first and second outer surfaces, the plurality of cavities aligned in an annular array, wherein a first gel is disposed in each of the plurality of cavities; a plurality of wedge assemblies, each of the plurality of wedge assemblies removably insertable into one of the plurality of cavities, each of the plurality of wedge assemblies comprising an outer cover and a second gel; a plurality of cable entry passages, each of the plurality of cable entry passages defined between one of the plurality of cavities and one of the plurality of wedge assemblies; a plurality of barrier members, each of the plurality of barrier members disposed between one of the plurality of cavities and one of the plurality of wedge assemblies and in contact with the first gel disposed in the respective cavity and the second gel of the respective wedge assembly, wherein each of the plurality of barrier members comprises a band and a plurality of fingers extending from the band; and a plurality of bushings, each of the plurality of bushings disposed in one of the plurality of cable entry passages, wherein each of the plurality of bushings comprises a conical body defining a central passage, wherein the conical body further comprises a tip, the tip defining a retention lip, and wherein the retention lip contacts tip ends of the fingers of the associated barrier member.

16 . The butt closure base of claim 15 , wherein each of the plurality of barrier members is conical.

17 . The butt closure base of claim 15 , wherein a slot is defined through the conical body and in communication with the central passage.

18 . The butt closure base of claim 15 , wherein the conical body further defines an exterior tie-wrap channel.

19 . The butt closure base of claim 15 , wherein each of the plurality of cavities is defined between surfaces of opposing sidewalls, and wherein the surfaces extend substantially parallel to each other.

20 . The butt closure base of claim 15 , wherein each of the plurality of wedge assemblies further comprises a main pressure plate in contact with the second gel, the main pressure plate movable along the longitudinal axis to apply pressure to the second gel.

21 . The butt closure base of claim 15 , wherein each of the plurality of wedge assemblies further comprises an outer flange extending from the outer cover, and wherein each of the plurality of wedge assemblies further comprises a plurality of apertures defined at an intersection between the outer flange and the outer cover, and wherein the second gel extends through each of the plurality of apertures.

22 . The butt closure base of claim 15 , further comprising a plurality of cable collar assemblies, each of the plurality of cable collar assemblies insertable into one of the plurality of cavities, each of the plurality of cable collar assemblies comprising a cable clamp and a frame, the frame defining a passage and a slot.

23 . A butt closure base, comprising:
