Abstract

A sealed terminal has a housing, a splice tray, and a faceplate. The housing has an interior compartment and a first perimeter flange defining an opening into the interior compartment. The splice tray is positioned in the interior compartment and is configured to support a module or a cartridge. The faceplate has a plurality of ports and a second perimeter flange extending at a perimeter edge of the faceplate. The sealed terminal also has at least one connection bracket and a gasket for connecting the housing and the faceplate to each other. The connection bracket has a slot receiving the first perimeter flange and the second flange in an abutting position. The gasket is positioned between the first perimeter flange and the second perimeter flange and configured to seal any gap therebetween.

First claim

The invention claimed is:

1. A sealed terminal, comprising:
a housing comprising an interior compartment and a first perimeter flange defining an opening into the interior compartment;
a splice tray positioned in the interior compartment and configured to support a module or a cartridge;
a faceplate comprising a plurality of ports and a second perimeter flange extending at a perimeter edge of the faceplate;
at least two L-shaped connection brackets including a slot configured for receiving the first perimeter flange and the second flange in an abutting position, wherein the at least two L-shaped connection brackets comprise angled bolt connections configured for adjustably joining ends of the at least two L-shaped connection brackets together; and
a gasket positioned between the first perimeter flange and the second perimeter flange and configured to seal any gap therebetween.

2. The sealed terminal of claim 1 , wherein the gasket is attached to a rear surface of the faceplate.

3. The sealed terminal of claim 2 , wherein the gasket comprises a plurality of protrusions that are interference fit into a plurality of corresponding apertures in the rear surface of the faceplate.

4. The sealed terminal of claim 1 , wherein the at least two connection brackets comprises a plurality of connection brackets connected to each other.

5. The sealed terminal of claim 4 , wherein the plurality of connection brackets each comprises a slot for receiving the first perimeter flange and the second perimeter flange in the abutting position.

6. The sealed terminal of claim 1 , wherein the first perimeter flange and the second perimeter flange each comprise an angled surface and the slot comprises mating angled sidewalls defining sides of the slot.

7. The sealed terminal of claim 1 , wherein the gasket comprises a flat surface and an opposing beveled surface.

8. The sealed terminal of claim 7 , wherein the gasket comprises a narrow end at the outer perimeter and a wide end at the inner perimeter.

9. The sealed terminal of claim 1 , wherein the gasket comprises a stepped flange at the inner perimeter thereof.

10. The sealed terminal of claim 9 , wherein the faceplate comprises a ridge that follows a path of the gasket, the ridge configured to mate with the stepped flange of the gasket.

11. The sealed terminal of claim 1 , wherein the gasket comprises an S-shape configured to mate with the rear surface of the faceplate and a ridge on the rear surface of the faceplate.
