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 gasket for a sealed terminal of a housing, the gasket comprising:
a rectangular shape forming a perimeter around an opening; and
a cross-sectional shape comprising:
a first surface comprising a plurality of protrusions configured to be inserted into corresponding apertures of a faceplate of the housing, wherein at least the first surface is configured to mate to the faceplate;
a beveled second surface comprising an outer edge and a sloped surface, wherein the sloped surface is directly connected to the outer edge and the outer edge is directly connected to the first surface at a first end of the beveled second surface and the sloped surface slopes upward therefrom; and
a stepped flange connecting a second end of the beveled second surface to the first surface.

2. The gasket of claim 1 , wherein the beveled second surface further comprises a flat upper shelf connected directly to the stepped flange.

3. The gasket of claim 2 , wherein the outer edge extends away from the first surface at an angle of greater than 90 degrees.

4. The gasket of claim 3 , wherein the stepped flange comprises an S-shape having two segments separated by a step.

5. The gasket of claim 4 , wherein the two segments extend parallel to the outer edge.

6. The gasket of claim 1 , wherein at least one protrusion of the plurality of protrusions includes one or more side slits to enable compression of the at least one protrusion.

7. The gasket of claim 1 , wherein at least one protrusion of the plurality of protrusions includes an angular section cutout to enable compression of the at least one protrusion.

8. The gasket of claim 7 , wherein the angular section cutout includes a cutout angle of approximately 70 degrees.

9. The gasket of claim 1 , wherein the first surface is characterized by a dimension of between 0.30 inches and 0.50 inches.

10. The gasket of claim 1 , wherein the beveled second surface comprises an outer edge that is characterized by a dimension of between 0.04 inches and 0.06 inches.

11. The gasket of claim 10 , wherein the outer edge extends at an angle of approximately 95 degrees with respect to the first surface.

12. The gasket of claim 10 , wherein the beveled second surface extends from the outer edge at an angle of between 25 degrees and 35 degrees with respect to the first surface.

13. The gasket of claim 1 , wherein the housing comprises an optical fiber terminal housing.

14. The gasket of claim 13 , wherein the optical fiber terminal housing comprises one or more perimeter flanges configured to compress the gasket to the faceplate.

15. The gasket of claim 1 , wherein the rectangular shape is characterized by a length having a dimension between 6.0 inches and 7.0 inches.

16. The gasket of claim 1 , wherein the rectangular shape is characterized by a width having a dimension between 4.5 inches and 5.5 inches.
