Abstract

A re-enterable enclosure for a cable splice includes a first cover member and a second cover member configured for engagement with each other, and movable between an open position and a closed position. The first and second cover members form a cavity for enclosing the cable splice when the cover members are in the closed position. Internal walls in at least one of the first and second cover members are configured to define a sealant containment space that at least partially surrounds the cavity. At least one latch is configured to maintain the first and second cover members in the closed position, the at least one latch configured to exert a compression force along a line extending through the sealant containment space.

Claims (16)

1. A re-enterable enclosure for a cable splice, the enclosure comprising:

a first cover member;

a second cover member configured for engagement with the first cover member, the first and second cover members movable between an open position and a closed position, wherein the first and second cover members form a cavity for enclosing the cable splice when the cover members are in the closed position;

internal walls in at least one of the first and second cover members, the internal walls configured to define a sealant containment space that at least partially surrounds the cavity;

a sealant disposed in the sealant containment space, wherein the sealant comprises pre-formed shapes retained in the sealant containment space defining generally circular cable entry paths when the first and second cover members are in the closed position;

at least one latch configured to maintain the first and second cover members in the closed position, the at least one latch configured to exert a compression force along a line extending through the sealant containment space.

2. The enclosure of claim 1 , wherein the first and second cover members are rotatably joined adjacent a first longitudinal edge of the cavity, and wherein the sealant containment space extends adjacent at least a second longitudinal edge of the cavity opposite the first longitudinal edge, the at least one latch configured to exert the compression force along a line extending through the sealant containment space that extends adjacent the second longitudinal edge of the cavity.

3. The enclosure of claim 2 , wherein the at least one latch is configured to exert the compression force at a plurality of points along the second longitudinal edge of the cavity.

4. The enclosure of claim 2 , wherein the at least one latch is configured to exert the compression force along substantially the entire second longitudinal edge.

5. The enclosure of claim 1 , wherein the internal walls in at least one of the first and second cover members comprise at least one internal wall in one of the first and second cover members configured to telescope into a sealant containment space in the other of the first and second cover members and thereby compress sealant material contained therein when the first and second cover members are in the closed position.

6. The enclosure of claim 1 , wherein internal walls in at least one of the first and second cover members comprise internal walls in both of the first and second cover members, the internal walls defining a plurality of sealant containment spaces that at least partially surround the cavity.

7. The enclosure of claim 6 , wherein the first and second cover members define cable entry paths into the cavity, and wherein the sealant containment spaces surround the cable entry paths when the first and second cover members are in the closed position.

8. The enclosure of claim 7 , wherein the cable entry paths define generally circular apertures into the cavity, wherein the sealant surrounding the cable entry paths is coaxially aligned with the cable entry paths.

9. The enclosure of claim 1 , wherein surfaces of the pre-formed shapes define the cable entry paths, and wherein said surfaces have a longitudinal cross-section that is one of flat, convex and concave.

10. The enclosure of claim 1 , wherein when the latch maintains the first and second cover members in the closed position, the latch in maintained in position by a primary latch retention means and a secondary latch retention means.

11. The enclosure of claim 1 , wherein when the latch comprises a single unit.
