US 8,014,837 B2 · Telecommunications chassis and card

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.

A chassis for holding telecommunications cards, comprising:

a housing having first and second horizontal surfaces and first and second vertical sidewalls, the first vertical sidewall having a plurality of holes;
and
a first bracket mounted to the housing, the first bracket having a first side and a second side perpendicular to the first side, wherein the first side of the first bracket has a first horizontal dimension and a first and second set of holes and wherein the second side of the first bracket has a second horizontal dimension different than the first horizontal dimension and has a first and second set of holes, wherein when the first set of holes of the first side of the first bracket align with at least a portion of the plurality of holes of the first sidewall, the second set of holes of the first side of the first bracket are blocked by the first vertical sidewall and when the first set of holes of the second side of the first bracket align with at least a portion of the plurality of holes of the first vertical sidewall, the second set of holes of the second side of the first bracket are blocked by the first vertical sidewall.

A chassis for holding telecommunications cards, comprising:

first and second horizontal surfaces and first and second vertical sidewalls separating the first and second horizontal surfaces, wherein the first vertical sidewall has a plurality of at least three holes;
and
a first bracket having a first side and having a second side substantially perpendicular to the first side, the first side having a set of at least two holes and the second side having a set of at least two holes, wherein the set of at least two holes of the first side align with a first set of at least two but fewer than all of the plurality of holes of the first vertical sidewall when the first side abuts the first vertical sidewall and wherein the set of at least two holes of the second side align with a second set of at least two but fewer than all of the plurality of holes of the first vertical sidewall when the second side abuts the first vertical sidewall, the first set comprising at least one hole not included in the second set.

A method of installing brackets on a chassis, comprising:

providing a housing having first and second horizontal surfaces and first and second vertical sidewalls, the first vertical sidewall having a plurality of holes;
providing a first bracket having a first side and a second side perpendicular to the first side, wherein the first side of the first bracket has a first horizontal dimension and a first and second set of holes and wherein the second side of the first bracket has a second horizontal dimension different than the first horizontal dimension and has a first and second set of holes;
when installing the first bracket such that the first side abuts the first vertical sidewall, aligning the first set of holes of the first side of the first bracket with at least a portion of the plurality of holes of the first sidewall and blocking the second set of holes of the first side of the first bracket by the first vertical sidewall;
and
when installing the first bracket such that the second side abuts the first vertical sidewall, aligning the first set of holes of the second side of the first bracket with at least a portion of the plurality of holes of the first vertical sidewall and blocking the second set of holes of the second side of the first bracket by the first vertical sidewall.
