Brian J. McClellan - Richfield MN
Dale C. Madsen - Jordan MN
Joseph S. Czyscon - Plymouth MN
Steven W. Skradde - Lino Lakes MN
Derek G. Sayres - Lonsdale MN

Assignee:

ADC Telecommunications, Inc. - Eden Prairie MN

International Classification:

G02B 636

US Classification:

385 88, 385 53

Abstract:

Telecommunications chassis and associated modules for use with the telecommunications chassis are disclosed. Embodiments of the telecommunications chassis include structures such as horizontal channels and/or horizontal surfaces with ridges and/or slots in one surface and slots in ridges of another for receiving edges of modules that mount within the chassis. Other structures of embodiments include divider slots in the horizontal surfaces that receive edges of divider walls to fix the divider walls in place, heat baffle surfaces included within the chassis, and/or cable guides with radius limiters. Module embodiments include structures such as faceplates with angled portions with fiber optic cable connections directed toward the fiber cables direction of travel. Other module structures include shells that enclose the circuit board and/or provide angled portions with fiber optic cable connections. Module embodiments may also include circuitry for converting electrical signals to optical and optical signals to electrical, and the circuitry may selectively operate at multiple data rates.

International Classification:

H05K007/14
H05K007/18

US Classification:

361796, 361816, 361818, 3122231, 174 35 MS

Abstract:

A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation and flame containment features while accommodating a high density of the circuitry cards. Embodiments include an inner housing with a double-layer middle floor dividing the chassis into top and bottom chambers. Each layer has partially aligned slots, and an air gap is provided between the two layers. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers. Projections and grooves are provided on the inner surfaces of the inner housing to receive circuit cards having a guide on one edge and a fin on another. The circuit card includes conductor structures such as multiple board layers with paired and segregated conductors. The circuit card also includes some components positioned to cooperate with the ventilation features of the chassis and includes some components chosen for low-power consumption or reduced flammability.

International Classification:

H05K 5/02

US Classification:

37941304, 361796, 361752

Abstract:

A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation structures and may accommodate a high density of the circuitry cards. Embodiments may include one surface with one or more ridges for rigidity and ventilation and fin slots for receiving circuit card guide fins. Embodiments may include a surface with knockouts for receiving circuit card guides. Embodiments may also include multiple bracket hole patterns for mounting brackets for different racks or for a single multi-rack bracket having more than one mounting hole pattern. The circuit card includes conductor structures such as multiple board layers with paired and segregated conductors. The circuit card also includes some components positioned to cooperate with the ventilation structures of the chassis and includes some components chosen for low-power consumption or reduced flammability.

International Classification:

G02B 6/00
F16L 3/22

US Classification:

385134, 248 681

Abstract:

A fitting for a cable trough system, the fitting including a bottom wall and side walls extending from at least a first terminal end to a second terminal end and forming a trough therebetween, the side walls being curved in a longitudinal direction, and an end portion formed at each of the first and second terminal ends, the end portion including first and second guiding surfaces defining a space therebetween, and a spring member positioned in the space. The space is sized to receive a terminal end of a trough member of the cable trough system, and wherein the spring member is positioned to engage the terminal end of the trough member to couple the trough member to the fitting. Other cable routing devices can also be used.
