Abstract

Apparatus for enclosing a plurality of fiber optic cables in a sealed environment includes a housing, a lid, a hollow body projecting from the housing, at least one grommet disposed in the hollow body for securing one or more fiber optic cables in an orifice accessed by a slit provided therein and a cap disposed in front of the hollow body to compress the grommet and seal components passing through the grommet into the housing. The grommet is a single body with a plurality of orifices for receiving a plurality of fiber optic cables or a plurality of individually formed grommets each having one orifice.

Claims

1. An apparatus comprising:

a housing;

a lid;

a hollow body projecting from the housing;

at least one grommet disposed in the hollow body for securing one or more fiber optic cables in an orifice accessed by a slit provided therein; and

a cap disposed in front of the hollow body to compress the grommet and seal components passing through the grommet into the housing.

2. The apparatus of claim 1, wherein the housing is substantially rectangular in shape.

3. The apparatus of claim 2, wherein the housing further comprises a front face having an opening where the hollow body projects from.

4. The apparatus of claim 3, wherein the hollow body projects perpendicularly from the front face of the housing.

5. The apparatus of claim 1 wherein the grommet is a single body with a plurality of orifices for receiving a plurality of fiber optic cables.

6. The apparatus of claim 5 wherein the grommet further comprises a plurality of slits corresponding to the plurality of orifices for gaining access to the plurality of orifices.

7. The apparatus of claim 1 wherein the grommet further comprises a plurality of individually formed grommets;

each grommet comprising one orifice.

8. The apparatus of claim 7 wherein each of the plurality of individual grommets further comprises a slit on a side of the grommet for accessing the orifice.

9. The apparatus of claim 8 wherein the plurality of individual grommets are grouped in a matrix;

the matrix sized to fit in the hollow body.

10. The apparatus of claim 1 wherein the cap further comprises a tray-like shape further comprising a plurality of flanges that correspond to a plurality of flanges provided on the hollow body.

11. The apparatus of claim 1 wherein the cap is a flat plate construction.

12. The apparatus of claim 1 wherein the cap further comprises a plurality of openings, each cap opening corresponding to a grommet orifice.

13. The apparatus of claim 1 wherein the lid is secured to the housing using a plurality of stud and nut combinations.

14. The apparatus of claim 1 wherein the lid is secured to the housing via a hinge assembly and one or more screws passing through the lid into the housing.

15. The apparatus of claim 1 wherein the grommet slit is a wavy line design.

16. The apparatus of claim 1 wherein the grommet slit is a straight line construction.

17. The apparatus of claim 1 wherein the at least one grommet is fabricated from a material selected from the group consisting of silicone rubber, neoprene rubber and neoprene foam rubber.

19. The apparatus of claim 17 wherein the multi-part housing further comprises two halves.

18. An optical fiber interconnection sealing apparatus comprising:

a multi-part housing defining an enclosure;

one or more hollow bodies projecting from the housing;

at least one grommet disposed in each of the one or more hollow bodies for securing one or more fiber optic cables in an orifice accessed by a slit provided therein; and

a cap disposed in front of each of the one or more hollow bodies to compress the grommet and seal components passing through the grommet into the housing.
