Abstract

Certain aspects of the present disclosure relate to a telecommunication enclosure having a configuration that can be readily customized in the factory to satisfy customer specifications and can also be readily upgraded in the field. In certain examples, the telecommunication enclosure includes a main housing defining a plurality access ports. A plurality of different add-on components can selectively be coupled to the main housing at the access ports in sealed relation to the main housing. The add-on components can include visual indicators which are visible from outside the main housing when the add-on components are mounted to the main housing.

First claim

What is claimed is:

1 . A telecommunication enclosure comprising:
a main housing including:
a housing body having an open end;
an end piece that detachably mounts to the housing body at the open end of the housing body for closing the open end of the housing body, the end piece defining at least one access port;
a main housing gasket for sealing between the end piece and the housing body when the end piece is mounted at the open end of the housing body; a cable pass-through sleeve that detachably mounts to the end piece at a mounting location corresponding to the access port, the cable pass-through sleeve having a first end and an opposite second end, the first end of the cable pass-through sleeve being configured to detachably connect to the end piece at the mounting location, and the sleeve being positioned to surround the access port when connected to the end piece at the mounting location; an access port gasket that surrounds the access port for sealing between the first end of the cable pass-through sleeve and the end piece when the cable pass-through sleeve is mounted at the mounting location of the end piece; and a cable sealing gel block that mounts in the cable pass-through sleeve, the cable sealing gel block including first and second gel pressurization structures defining cable pass-through locations, a volume of gel positioned axially between the first and second gel pressurization structures, and an actuator for forcing the first and second gel pressurization structures axially toward one another to pressurize the volume of gel, wherein when the volume of gel of the cable sealing gel block is pressurized while the cable sealing gel block is installed in the cable pass-through sleeve, a circumferential exterior of the volume of gel provides circumferential sealing with respect to a circumferential interior of the cable pass-through sleeve and the volume of gel also conforms about and seals about cables routed through the cable sealing gel block.

2 . The telecommunication enclosure of claim 1 , wherein the actuator includes a trigger that is used to pressurize the volume of gel, wherein the trigger is accessible at the second end of the sleeve when the cable sealing gel block is installed in the cable pass-through sleeve.

3 . The telecommunication enclosure of claim 1 , wherein the cable sealing gel block loads into the cable pass-through sleeve through the first end of the cable pass-through sleeve, and wherein the second end of the cable pass-through sleeve includes a gel block retention lip for axially retaining the cable sealing gel block within the cable pass-through sleeve.

4 . The telecommunication enclosure of claim 1 , wherein the cable sealing gel block is too large to fit through the access port.

5 . The telecommunication enclosure of claim 3 , wherein the cable sealing gel block is required to be loaded into the cable pass-through sleeve before the cable pass-through sleeve is connected to the end piece, and wherein the cable pass-through sleeve is required to be detached from the end piece to remove the cable sealing gel block from the cable pass-through sleeve.

6 . The telecommunication enclosure of claim 1 , wherein the housing body is a dome having a closed end opposite the open end, and wherein the end piece is a base.

7 . The telecommunication enclosure of claim 1 , wherein the first end of the cable pass-through sleeve is connected to the end piece by fasteners.

8 . The telecommunication enclosure of claim 7 , wherein the access port defines a central port axis, wherein the fasteners include threaded studs that extend through the end piece and are individually sealed relative to the end piece, and wherein the threaded studs are circumferentially spaced about the central port axis.

9 . The telecommunication enclosure of claim 8 , wherein the cable pass-through sleeve includes outer radial projections at the first end of the cable pass-through sleeve, wherein the radial projections each define a stud receptacle for receiving one of the threaded studs, and wherein once the threaded studs have been received within the stud receptacles the first end of the cable pass-through sleeve can be clamped against an exterior side of the end piece by threading nuts on the threaded studs.

10 . The telecommunication enclosure of claim 9 , wherein the stud receptacles are open-sided receivers, and wherein the studs can be installed in the open-sided receivers by positioning the cable pass-through sleeve over the access port in co-axial alignment with the central port axis and then rotating the cable pass-through sleeve about the central port axis until the threaded studs are received within the open-sided receivers.

11 . The telecommunication enclosure of claim 10 , wherein the open-sided receivers are hooks.

12 . The telecommunication enclosure of claim 7 , wherein the fasteners are ground wire terminals, wherein the ground wire terminals each include a threaded stud having a first threaded end projecting inwardly from an interior side of the end piece, a second threaded end projecting outwardly from an exterior side of the end piece, and an intermediate flange that abuts the interior side of the end piece.

13 . The telecommunication enclosure of claim 12 , wherein each threaded stud is part of a connection assembly, each connection assembly including: a) one of the threaded studs; b) a first nut that threads on the first threaded end of the threaded stub for securing a terminal lug of an interior grounding wire to the threaded stud; c) a second nut that threads on the second threaded end of the threaded stud for securing a terminal lug of an exterior grounding wire to the threaded stud and for abutting the intermediate flange against the interior side of the end piece such that the threaded stud is secured to the end piece; and d) a third nut threaded on the second end of the threaded stud for securing the cable pass-through sleeve to the threaded stud.

14 . A telecommunication enclosure comprising:
a main housing including:
a housing body having an open end;
an end piece that detachably mounts to the housing body at the open end of the housing body for closing the open end of the housing body, the end piece defining a first access port, a second access port, and a third access port;
a main housing gasket for sealing between the end piece and the housing body when the end piece is mounted at the open end of the housing body; a cable pass-through sleeve that detachably mounts to the end piece at a mounting location corresponding to the access port, the cable pass-through sleeve having a first end and an opposite second end, the first end of the cable pass-through sleeve being configured to detachably connect to the end piece at the mounting location, and the sleeve being positioned to surround the access port when connected to the end piece at the mounting location; a first access port gasket that surrounds the first access port for sealing between the first end of the cable pass-through sleeve and the end piece when the cable pass-through sleeve is mounted at the mounting location of the end piece, the second access port surrounded by another access port gasket and the third access port surrounded by a further access port gasket; and a cable sealing gel block that mounts in the cable pass-through sleeve, the cable sealing gel block including first and second gel pressurization structures defining cable pass-through locations, a volume of gel positioned axially between the first and second gel pressurization structures, and an actuator for forcing the first and second gel pressurization structures
