摘要:
A telecommunications cable section (12) for connection with telecommunications or signaling equipment or other outside plant equipment, wherein the cable section (12) comprises a plurality of conductors (30) surrounded by an intermediate layer of corrugated material (32). A flexible braided or mesh protective sheathing (34) substantially surrounds the intermediate layer (32). The braided sheathing (34) is preferably a braided or mesh sock or tubular sleeve or sleeve of copper or other metal or material. An exterior layer of substantially moisture-proof shrinkable tubing (36) substantially surrounds the braided sheathing (34).
摘要:
A telecommunications equipment enclosure (10) that more effectively dissipates heat from electronic cards without transferring the heat to adjacent cards and without transferring the heat to air within an enclosed chamber surrounding the cards. The enclosure (10) includes a floor (12) and a plurality of card-receiving sleeves (14) attached to the floor (12). Each of the sleeves (14) defines a separate enclosed cell or holder that is configured for receiving and enclosing a single electronic card. The sleeves (14) are spaced apart to define a plurality of open air channels therebetween for convecting heat away from the sleeves (14) and the cards received therein while preventing heat from transferring from sleeve to sleeve.
摘要:
A pressurization control device (10) for controlling positive pressurization of an electronic equipment enclosure, such as, for example, a telecommunications equipment enclosure (12 or 14), wherein the device (10) combines and integrates a number of valves or other control components and functions into a single, common valve body (28) or manifold providing a single, shared penetration point (54) into the enclosure (12 or 14), thereby advantageously minimizing the number of penetrations into and potential leakage points from the enclosure (12 or 14). The valves or other control components may be substantially conventional and may include, for example, a cable air tube connection fitting (30); a pressure cutoff valve (32); a pressure relief valve (34); and a static pressure valve or air stem (36); an express fitting (38); and an on/off valve (40).

摘要:
A cable interface (10) operable to interface a cable trunk line with an electronic equipment enclosure (12) via a pendant cable (14), thereby providing for quick and convenient connection and disconnection, when desired, of the equipment enclosure (12) from the pendant cable (14). The equipment enclosure (12) may house a variety of electronic equipment, such as, for example, telecommunications, signaling, and similar electronic equipment, including, for example, repeater and doubler cards. The preferred cable interface (10) broadly comprises a first connector half (16); a mounting plate (18); a second connector half (20); a free-spinning nut (22); a security cover (24); and a flexible cable extension (26). The security cover (24) cooperates with the second connector half (20) to restrict unauthorized access to the connection.
摘要:
A telecommunications equipment enclosure (10) that dissipates into the ambient environment heat internally generated by signal repeater cards and other electronic equipment stored therein, thereby prolonging equipment life and preventing premature failure due to damaging levels of retained heat. Equipment-receiving sleeves (20) are removably arranged concentrically about the interior of a cylindrical housing (12). The housing (12) is fitted with a lid (14) having a cylindrically protruding portion (48). Cooling fins (16) operable to conduct and dissipate heat are attached to the exterior of the housing (12). Each sleeve (20) is able to conduct heat away from the heat-generating equipment received therein, and to transfer the heat along two distinct thermally conductive pathways. Surge protection (60) is provided on a removable circuit board (62) located adjacent each sleeve (20) and replaceable without removing the sleeve (20) or otherwise disrupting functioning of the cards or other electronic equipment.
摘要:
A modular electronic equipment enclosure (10) for housing telecommunications, signaling, or other electronic equipment. The enclosure (10) separates into modules for easier module-by-module installation. The preferred enclosure (10) broadly comprises three separable modules, including a housing module (12); a mounting structure (14); and a cable interface module (16). The housing module (12) receives, retains, and protectively encloses the electronic equipment. The mounting structure (14) is operable to secure to a mounting surface and to provide the housing module (12) with an operating orientation which is either perpendicular or parallel to the mounting surface. The interface block (16) is coupled with the housing module (12) in any of two or more possible orientations. The interface block (16) including a first wire connector half (94) operable to couple with a corresponding second wire connector half (38) connected to the electronic equipment.
摘要:
An electronic equipment enclosure (10) for housing electronic equipment (11), and broadly comprising a pivot bracket (22); a plurality of sleeves (24), each being associated with a transmit terminal (26), a receive terminal (28), protective circuitry (30), and test circuitry (32); a spreader plate (38); and a heat sink (40). The pivot bracket (22) allows for tilting an outer housing (12) up to 30° relative to a mounting surface. The separate and distinct transmit and receive terminals (26,28) maintain minimum cross-talk and interference levels. The protective and the test circuitries (30,32) are located on daughter boards adjacent each sleeve (24) so as to be easily accessible. The spreader plate (38) is operable to force the sleeves (24) into direct contact with the interior surface of the outer housing (18). The heat sink (40) is operable to facilitate conductive heat transfer between the sleeves (24) and the lid (18).
摘要:
A telecommunications equipment mounting assembly is provided including a plate (12) presenting a plurality of separate, spaced apart mounting zones (24), together with generally U-shaped brackets (14) respectively secured to the plate (12) adjacent corresponding zones (24). A telecommunications equipment enclosure (16) is secured to each pair of bracket legs whereby the enclosures (16) are spaced from the plate (12). Preferably, the brackets are oriented at an oblique angle relative to the longitudinal axis of the plate (12) to facilitate cabling and interconnection of the electrical equipment within the enclosures (16). In alternate forms, a standoff leg assembly (56) is employed to secure the mounting plates (12) and associated hardware to an upright wall (62). This creates a cableway (80) between the plates (12) and the wall (62).
