Telecommunications enclosure including containment structures for O-rings

A telecommunications enclosure comprising:

• a first housing piece having a lower end centered about a central axis;
• a second housing piece that mounts at the lower end, the second housing piece including a sealing surface that encircles the central axis when the second housing piece is mounted at the lower end of the first housing piece;
• the lower end of the first housing piece and an upper end of the second housing piece including outer flanges that extend about the central axis and that are adjacent to one another when the first housing piece and the second housing piece are mounted together;
• a seal that is compressed between the first housing piece and the second housing piece to provide sealing therein between;
• a clamp that mounts about the outer flanges of the first housing piece and the second housing piece, the clamp defining a clamp channel that receives the outer flanges;
• and
• the first housing piece includes a sealing surface that opposes the sealing surface of the second housing piece when the second housing piece is mounted to the first housing piece, wherein the seal is compressed between the sealing surface of the first housing piece and the sealing surface of the second housing piece, and wherein the sealing surface of the second housing piece angles upwardly as the sealing surface of the second housing piece extends away from the central axis or the sealing surface of the first housing piece angles downwardly as the sealing surface of the first housing piece extends away from the central axis.

A telecommunications enclosure comprising:

• a first housing piece having an open end and a closed end;
• a second housing piece that mounts at the open end of the first housing piece with the second housing piece and the first housing piece aligned along a common central axis, the second housing piece including a seal channel that extends around the central axis, the seal channel having an open side opposite from a channel bed, the channel bed extending outwardly from the central axis to an outer lip that projects from the channel bed in a direction toward the first housing piece, the channel bed angling toward the first housing piece as the channel bed extends away from the central axis to the outer lip and the outer lip extending about the central axis;
• the first housing piece and the second housing piece including outer flanges that extend about the central axis and that are adjacent to one another when the first housing piece and the second housing piece are mounted together;
• a seal that mounts in the seal channel and is compressed between the first housing piece and the channel bed of the second housing piece to provide sealing therein between;
• and
• a clamp that mounts about the outer flanges of the first housing piece and the second housing piece, the clamp defining a clamp channel that receives the outer flanges.
