BACKGROUND

Telecommunications systems typically employ a network of telecommunications cables capable of transmitting large volumes of data and voice signals over relatively long distances. The telecommunications cables can include fiber optic cables, electrical cables, or combinations of electrical and fiber optic cables. A typical telecommunications network also includes a plurality of telecommunications enclosures integrated throughout the network of telecommunications cables. The telecommunications enclosures are adapted to house and protect telecommunications components such as splices, termination panels, power splitters, and wavelength division multiplexers. It is often preferred for the telecommunications enclosures to be re-enterable. The term “re-enterable” means that the telecommunications enclosures can be re-opened to allow access to the telecommunications components housed therein without requiring the removal and destruction of the telecommunications enclosures. For example, certain telecommunications enclosures can include separate access panels that can be opened to access the interiors of the enclosures and then closed to re-seal the enclosures. Other telecommunications enclosures take the form of elongated sleeves formed by wrap-around covers or half-shells having longitudinal edges that are joined by clamps or other retainers. Still other telecommunications enclosures include two half-pieces that are joined together through clamps, wedges, or other structures. Telecommunications enclosures are typically sealed to inhibit the intrusion of moisture or other contaminants. Improvements in seal design are desired.

SUMMARY

The present disclosure relates generally to an enclosure sealing unit. In one possible configuration, and by non-limiting example, the sealing unit includes a first and second body, where the second body is disposed on the first body and is softer than the first body.

In one aspect of the present disclosure, a seal for a telecommunications enclosure is disclosed. The seal includes a first body made of a first material. The first body defines a port and the port defines a port axis. The first body further includes a first axial face, an opposite second axial face, and a peripheral surface. The peripheral surface surrounds the first body between the first axial face and second axial face and the peripheral surface further surrounds the port. The seal also includes a second body made of a second material. The second body is disposed on at least the peripheral surface of the first body. The second material is softer than the first material of the first body.

In another aspect of the present disclosure, a seal for a telecommunications enclosure is disclosed. The seal includes a main body having flat top surface, generally flat side surfaces, and an arcuate shaped bottom surface. The main body is comprised of a first material. The seal includes at least one port passing through the main body. The port has tapered walls. The port also includes a first seam in the main body that connects the port to a single side surface of the main body. The first seam is movable between an open position and a closed position. When in the open position, the first seam allows lateral access to the port. The seal includes a second body comprised of a second material where the second material is softer than the first material. The second body is disposed on the top, bottom, and side surface of the main body. The second body is also deposited on the tapered walls of the port.

A variety of additional aspects will be set forth in the description that follows. The aspects can relate to individual features and to combinations of features. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.
