Sealing interface for a telecommunications enclosure

摘要

A sealing interface (26) that utilizes an elastomeric sealing member (28) is disclosed herein. The sealing interface (26) is configured to provide effective sealing while requiring only relatively low amounts of force to deform the elastomeric sealing member (28) sufficiently to form an effective seal.

主权项

1. An enclosure for telecommunications equipment comprising:
first and second housing pieces that fit together to form at least a portion of the enclosure, the first and second housing pieces meeting at a sealing interface, the sealing interface including a sealing channel section of the first housing piece and a sealing rib of the second housing piece, the sealing channel section defining a sealing channel, the sealing rib projecting into the sealing channel when the first and second housing pieces are fitted together; the sealing interface including an 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; the sealing interface including a void region defined between the second side of the elastomeric sealing member and the closed end of the sealing channel; and the sealing rib having a base end and a free end, the free end of the sealing rib engaging the first side of the elastomeric sealing member to form a first axial seal location when the first and second housing pieces are fitted together, the sealing channel section engaging the second side of the elastomeric sealing member to form second and third axial seal locations when the first and second housing pieces are fitted together, the first axial seal location being positioned on an axial reference line that intersects the void region, the axial reference line being positioned between the second and third axial seal locations; wherein the elastomeric sealing member has an H-shaped transverse cross-sectional profile, 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 at the first side of the elastomeric sealing member to provide the first axial seal location, and 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, the second and third axial seal locations being respectively positioned on opposite sides of the void region when the first and second housing pieces are fitted together.
