Abstract

A sealant-filled enclosure assembly for environmentally protecting a connection between cables includes a housing and a mass of sealant. The housing is selectively configurable between an open position to receive the connection and a closed position wherein the housing defines an enclosure cavity to contain the connection. The housing includes at least one sealant cavity and a port control system. The port control system includes a gate member that is selectively deflectable from a closed position, wherein the gate member blocks a cable port, to an open position, wherein the cable port is open to permit a cable to extend into the enclosure cavity through the cable port. The gate member is rigid or semi-rigid. The mass of sealant is disposed in the at least one sealant cavity.

First claim

That which is claimed is:

1. A method for environmentally protecting a connection between cables, the method comprising:
providing a sealant-filled enclosure assembly including:
a housing selectively configurable between an open position to receive the connection and a closed position wherein the housing defines an enclosure cavity to contain the connection, wherein the housing has a housing end through which a cable can be received and includes:
at least one sealant cavity; and
a port control system including:
a first gate member that is selectively deflectable from a closed position, wherein the first gate member blocks a first cable port, to an open position, wherein the first cable port is open; and
a second gate member that is selectively deflectable from a closed position, wherein the second gate member blocks a second cable port, to an open position, wherein the second cable port is open to permit a second cable to extend into the enclosure cavity through the second cable port;

wherein the first and second gate members are located laterally side-by-side on the housing end; and
wherein each of the first and second gate members is rigid or semi-rigid and is free of tear and shear lines; and

a mass of sealant disposed in the at least one sealant cavity;

selectively deflecting the first gate member to its open position to open the first cable port;
selectively deflecting the second gate member to its open position to open the second cable port;
installing the connection in the enclosure cavity including installing the first cable in the first cable port and installing the second cable in the second cable port such that the first cable extends into the enclosure cavity through the first cable port and the second cable extends into the enclosure through the second cable port; and
closing the housing about the connection;
wherein the step of deflecting the first gate member into its open position to open the first cable port and the step of deflecting the second gate member into its open position to open the second cable port each precede the step of installing the first cable in the first cable port and installing the second cable in the second cable port.

2. The method of claim 1 wherein the first gate member is a unitary gate panel.

3. The method of claim 1 wherein the first gate member has a gate width greater than the diameter of the largest cable intended to be protected using the sealant-filled enclosure assembly.

4. The method of claim 3 wherein the gate width is between about 5 and 200 percent greater than the diameter of the largest cable intended to be protected using the sealant-filled enclosure assembly.

5. The method of claim 1 wherein the housing includes a cover member and the first gate member is integrally and unitarily molded with the cover member.

6. The method of claim 1 wherein the first and second gate members and the first and second cable ports are located on the same side of the enclosure cavity.

7. The method of claim 1 wherein:
the housing includes first and second cover members that, when closed, collectively define the enclosure cavity and the cable port;
the first and second gate members are located on the first cover member; and
the port control system further includes third and fourth gate members located on the second cover member;
when the first and second cover members are closed, the first and third gate members are disposed opposite one another to collectively define the first cable port when each of the first and third gate members is deflected into its open position; and
when the first and second cover members are closed, the second and fourth gate members are disposed opposite one another to collectively define the second cable port when each of the second and fourth gate members is deflected into its open position.

8. The method of claim 1 wherein the sealant-filled enclosure assembly is configured such that, when the housing is closed about the connection, the connection displaces an overflow portion of the sealant mass from the enclosure cavity through the first and second ports.

9. The method of claim 1 wherein the sealant is an elastically elongatable gel.
