Abstract

A sealed terminal has a housing, a cover, a splice tray, an adapter plate, and a splice chip. The cover is connected to the housing to close an interior compartment and has input ports for receiving one or more cables and an output adapter module having a plurality of distribution ports. The splice tray is positioned in the interior compartment and has one or more cable retainers configured to route the one or more cables within the interior compartment. The adapter plate is connected to the splice tray and has a plurality of adapters for connecting the one or more cables to the distribution ports. The splice chip is connected to the splice tray and has a plurality of slots for receiving and routing the one or more cables. The housing includes a radiused wall for routing the cables within the interior compartment without bending the cables.

First claim

1 . A sealed terminal, comprising:
a housing comprising an interior compartment; a cover connected to the housing to close the interior compartment and comprising:
a plurality of input ports for receiving one or more cables; and
an output adapter module comprising a plurality of distribution ports each for receiving a connector for active connection to the one or more cables, and
a splice tray positioned in the interior compartment and comprising one or more cable retainers configured to route the one or more cables within the interior compartment; an adapter plate connected to the splice tray and comprising a plurality of adapters for connecting the one or more cables to the plurality of distribution ports; and a splice chip connected to the splice tray and comprising a plurality of slots for receiving and routing at least one of the one or more cables.

2 . The sealed terminal of claim 1 , wherein the housing includes a distal end having a radiused wall for routing the one or more cables within the interior compartment without bending of the one or more cables.

3 . The sealed terminal of claim 2 , wherein the splice tray comprises a radiused wall parallel to the radiused wall of the housing.

4 . The sealed terminal of claim 1 , wherein the one or more cables is a flat drop cable.

5 . The sealed terminal of claim 1 , wherein the one or more cables is a round drop cable.

6 . The sealed terminal of claim 1 , wherein the plurality of distribution ports comprise flexible ports.

7 . The sealed terminal of claim 6 , wherein the flexible port comprises a seal, a press-in element, and a clip.

8 . The sealed terminal of claim 6 , wherein the connector is a round plug-in connector configured to contact the seal.

9 . The sealed terminal of claim 1 , wherein the splice tray comprises a first cavity and a second cavity separated by an interior support wall.

10 . The sealed terminal of claim 9 , wherein the first cavity and the second cavity are formed by a perimeter wall surrounding and perpendicular to the interior support wall.

11 . The sealed terminal of claim 10 , wherein the perimeter wall is radiused for routing the one or more cables within the interior compartment without bending of the one or more cables.

12 . The sealed terminal of claim 9 , wherein splice chip is connected to the interior support wall.

13 . The sealed terminal of claim 12 , wherein the splice chip comprises chip ends at edges of a base of the splice chip and the interior support wall comprises a plurality of undercuts configured to receive the plurality of chip ends so as to couple the splice chip to the splice tray.

14 . The sealed terminal of claim 1 , wherein the plurality of adapters correspond to the plurality of distribution ports.

15 . The sealed terminal of claim 14 , wherein the adapter plate comprises four adapters and the output adapter comprises four distribution ports.

16 . The sealed terminal of claim 14 , wherein the adapter plate comprises twelve adapters and the output adapter comprises twelve distribution ports.

17 . The sealed terminal of claim 1 , wherein one or more cable retainers comprise a plurality of prongs for contacting at least one of the one or more cables.

18 . The sealed terminal of claim 1 , wherein the one or more cables comprise at least one input cable and a plurality of spliced cables connected to the at least one input cable and being greater in number than the at least one input cable.

19 . A sealed terminal, comprising:
a housing comprising an interior compartment; a cover connected to the housing to close the interior compartment and comprising:
a plurality of input ports for receiving one or more cables; and
an output adapter module comprising a plurality of distribution ports each for receiving a connector for active connection to the one or more cables, and
a splice tray positioned in the interior compartment and comprising one or more cable retainers configured to route the one or more cables within the interior compartment; an adapter plate connected to the splice tray and comprising a plurality of adapters for connecting the one or more cables to the plurality of distribution ports; and a splice chip connected to the splice tray and comprising a plurality of slots for receiving and routing at least one of the one or more cables, wherein the housing includes a distal end having a radiused wall for routing the one or more cables within the interior compartment without bending of the one or more cables, wherein the splice tray comprises a first cavity and a second cavity separated by an interior support wall, wherein the first cavity and the second cavity are formed by a perimeter wall surrounding and perpendicular to the interior support wall, and wherein the perimeter wall is radiused and parallel to the radiused wall of the housing for routing the one or more cables within the interior compartment without bending of the one or more cables.

20 . The sealed terminal of claim 19 , wherein the one or more cables comprise at least one input cables and a plurality of spliced cables connected to the at least one input cable and being greater in number than the at least one input cable.
