Sealing interface for a telecommunications enclosure

1. An enclosure for telecommunications equipment comprising:

first and second housing pieces that fit together to form at least a portion of the enclosure;

a sealing channel section defined by the first housing piece, the sealing channel section defining a sealing channel;

a sealing rib defined by the second housing piece;

an elastomeric sealing member positioned within the sealing channel defined by the sealing channel section, the elastomeric sealing member having a first side that faces away from a closed end of the sealing channel and a second side that faces toward the closed end of the sealing channel;

when the first and second housing pieces are fitted together, the sealing rib engages the first side of the elastomeric sealing member to form a first axial seal location and the second side of the elastomeric sealing member form second and third axial seal locations, the first axial seal location being positioned on an axial reference line; and

a void region defined between the second side of the elastomeric sealing member and the closed end of the sealing channel, the void region being positioned between the second and third axial seal locations positioned at the closed end of the sealing channel when the first and second housing pieces are fitted together, and the axial reference line intersecting the void region;

wherein the second side of the elastomeric sealing member engages the closed end of the sealing channel to provide the second and third axial seal locations.

2. The enclosure of claim 1 , wherein the elastomeric sealing member has an H-shaped transverse cross-sectional profile.

3. The enclosure of claim 2 , wherein the H-shaped transverse cross-sectional profile includes two spaced-apart legs interconnected by a cross-member, wherein the sealing rib engages the cross-member to provide the first axial seal location.

4. The enclosure of claim 3 , wherein ends of the two spaced-apart legs at the second side of the elastomeric sealing member engage the closed end of the channel to provide the second and third axial seal locations.

5. The enclosure of claim 1 , wherein the first housing piece includes a base and the second housing piece includes a dome, and wherein the first and second housing pieces meet at a sealing interface that forms a perimeter seal between the base and the dome.

6. The enclosure of claim 5 , wherein the base is secured to the dome by first and second latches positioned opposite sides of the base, the first and second latches each having an open position, an intermediate position, and a final position.

7. The enclosure of claim 1 , wherein the elastomeric sealing member is a rubber material.

8. The enclosure of claim 1 , wherein the elastomeric sealing member is silicone rubber.

9. The enclosure of claim 1 , wherein the elastomeric sealing member has a sheet-like construction.

10. The enclosure of claim 1 , wherein the elastomeric sealing member is an elastic sheet.

11. The enclosure of claim 10 , wherein the elastic sheet bridges an open end of the sealing channel when the first and second housing pieces are fitted together.

12. The enclosure of claim 11 , wherein the sealing rib presses the elastic sheet into the sealing channel when the first and second housing pieces are fitted together.

13. The enclosure of claim 12 , wherein the elastic sheet includes a fixed end and a moveable end, and wherein the movable end moves when the sealing rib presses the elastic sheet into the sealing channel.

14. The enclosure of claim 12 , wherein the sealing channel section includes first and second spaced-apart channel ribs that project outwardly from the closed end of the sealing channel, wherein the sealing rib engages the first side of the elastomeric sealing member to provide the first axial seal location, and wherein the first and second spaced-apart channel ribs engage the second side of the elastomeric sealing member to provide the second and third axial seal locations.
