The patent US12066674B2 describes a telecommunications enclosure designed to house telecommunications modules securely. The enclosure features a casing with an inner cavity and a base that can be removably coupled to the casing. A key component of this design is the plurality of sealing assemblies, each comprising an elastically deformable sealing module positioned between a first and a second member. These sealing assemblies are equipped with movable portions that can transition between open and closed positions, allowing for the insertion and securement of cables through defined cable ports. The elastically deformable sealing module is designed to encircle the cable, ensuring a tight fit when the movable portions are in the closed position.

Additionally, the patent outlines the functionality of the sealing assemblies, which can be individually coupled and decoupled from the base. The design includes features such as pressure elements to compress the sealing module and a retaining body with recesses for each sealing assembly. The sealing modules can be made from gel-like or elastomeric materials, enhancing their ability to maintain a seal while allowing for cable access. The claims also specify that the movements of the sealing assembly's members do not affect the elastically deformable sealing module's access, ensuring that the cable can be inserted or removed without compromising the enclosure's integrity. This innovative design aims to improve the efficiency and reliability of telecommunications installations.
