Abstract

The present invention is directed to an enclosure for protecting a cable connection. The enclosure includes a sealing member contained within an inner shell. The sealing member is secured around the cable connection by slideably engaging a rigid outer shell over the inner shell. The inner shell has an external topography defining an inner shell profile and wherein the outer shell has an internal topography defining an outer shell profile such that the outer shell profile is similar to the inner shell profile.

First claim

What is claimed is:

1. An enclosure for protecting a cable connection, the enclosure comprising:
a sheet sealing member coated with a gel sealant attached to an inner shell along two longitudinal edges of the inner shell such that the sheet sealing member is contained within the inner shell when the inner shell is secured around the cable connection and a rigid outer shell that longitudinally slides over and engages with the inner shell,
wherein the outer shell imparts a radial compressive load to the inner shell to press the sealing member into contact with the cable connection to create an environmental seal, and
wherein the inner shell has an external topography defining an inner shell profile and wherein the outer shell has an internal topography defining an outer shell profile wherein the outer shell profile is similar to the inner shell profile.

2. The enclosure of claim 1 , wherein the inner shell has a tapered inner shell profile having a first diameter at a first end of the inner shell and a second larger diameter at the second end of the inner shell.

3. The enclosure of claim 1 , wherein inner shell is composed of two shell portions.

4. The enclosure of claim 3 , wherein the shell portions are connected by a hinge along one longitudinal edge of each shell portion.

5. The enclosure of claim 1 , further comprising at least one latch arm to secure the outer shell in place over the inner shell.

6. The enclosure of claim 1 , further comprising one or more strengthening ribs disposed on the exterior surface of the outer shell.

7. The enclosure of claim 1 , wherein the sheet sealing member comprises the gel sealant material coated on one of an elastomeric sheet and a volume compliant sheet.

8. The enclosure of claim 7 , wherein the gel sealant material comprises an oil swollen, cross-linked polymer network.
