The present invention generally relates to a cable management system for interconnecting electronics or fiber optic cables and more specifically to a cable management system for connecting an equipment system to multiple patch panels.
Numerous cable management systems exist today and are used in various electronics equipment applications, such as telecommunications, data transmission, networking, video and the like. Typically, to install a cable management system, a frame is securely mounted to the floor within the room in which the system is to be maintained. Multiple patch panels or boxes are then secured to the frame in a stacked arrangement. Each patch panel includes multiple connector ports (e.g. RJ45 connector ports) along the front face thereof. Each connector port is adapted to receive a plug on a mating cable that conveys a single data stream, such as for an individual user and the like, or multiple data streams.
Additionally, each patch panel includes connector modules electrically coupled to the connector ports and configured to receive a mating cable from an equipment system (e.g. a switching network). Typically, the equipment system is connected to the patch panels by a trunk cable. At the switching network, the trunk cables are connected to switch blades located within a switching network housing. In known cable management systems, the trunk cables extend to either side of the switching network housing and are then brought up either side of the frame before being connected to the corresponding patch panels. In doing so, the trunk cables do not interfere with the front face of the patch panels where the mating cables interface with the connector ports of the patch panels, but the trunk cables do increase the overall footprint of the system. Additionally, as the number of cables increases, heretofore, wire managers have been widened laterally relative to the patch panels or constructed deeper (i.e. in the direction transverse to the front face of the patch panels) thereby increasing the overall footprint of the system.
One problem associated with these known systems is that cable management systems are reaching the size limits afforded by certain standards and/or by physical constraints of rooms and environments in which they are mounted. Specifically, as the capacity of the cable management system increases, the number of individual cables similarly increases, and the cable mass is becoming prohibitive.
In at least some other known cable management systems, the trunk cables extend over the top of the frame prior to being connected to the corresponding patch panel. A problem associated with these known systems is that the routing of the trunk cables around the sides, and over the top of the frame leads to a larger cable mass. A larger cable mass causes additional heat and limits the amount of open space for the movement of air, thus decreasing the efficiency of the cable management system. Yet another problem associated with these known systems is that the trunk cables tend to interfere with the fans provided to cool the switching network. As such, the switching network may be subject to overheating.
A need remains for an improved cable management system having a more space efficient geometry.
In an exemplary embodiment of the present invention, a cable management system is provided. The cable management system includes an equipment system, and at least one patch panel having a connectivity interface. The connectivity interface is configured to connect with at least one cable extending from the equipment system. The cable management system also includes a manifold configured to be located between the equipment system and the patch panel. The manifold includes an inlet and an outlet, and the manifold is configured to direct the at least one cable from the equipment system to the connectivity interface.
Certain embodiments of the present invention may also include a manifold having a front wall, side walls, a back wall, and a top wall, wherein the inlet is oriented within the front wall, and the outlet is oriented within at least one of the top wall and the back wall. Optionally, the cable management system may include a frame, wherein the patch panel, the equipment system, and the manifold are secured to the frame.
Certain embodiments of the present invention may also include a patch panel having a front face including a plurality of connector modules oriented on an opposing side of the patch panel as the connectivity interface. Additionally, the manifold includes a front wall including the inlet, and the equipment system includes a front wall that is substantially aligned with the front face of the patch panel. Optionally, the cable may extend from the front wall of the equipment system, through the inlet, and is connected to the connectivity interface of the patch panel.
Certain embodiments of the present invention may also include a thermal management system for cooling at least one of the equipment system, the cable, and the patch panel. Optionally, the thermal management system includes a louvered cover having at least one vent for channeling airflow therethrough, and at least one fan coupled to the louvered cover for generating the airflow through the vent. Optionally, the thermal management system includes a duct in flow communication with the fan. In one embodiment, the duct may be coupled to the manifold for generating airflow through said manifold. Alternatively, the duct may be positioned within a gap between the manifold and the equipment system such that the duct is configured to generate airflow along a surface of the equipment system and a surface of the manifold.
An equipment system 32 (such as a switching network) is also shown in
A cable guide manifold 44 is also shown in
In one embodiment, the manifold 44 is positioned between the system 32 and the distribution assembly 16. Optionally, the manifold 44 may be positioned adjacent the system 32 or the patch panels 14. Alternatively, the manifold 44 may be positioned a distance from the system 32 or the patch panels 14. In one embodiment, the manifold 44 is securely attached to the support brackets 28 and 30. Alternatively, the manifold 44 may be moveable along the support brackets 28 and 30 between the system 32 and the patch panels 14 to direct and/or position the cables 42. In another alternative embodiment, additional manifolds may be provided to direct additional wires, such as, for example, the wires collected by the wire managers 18.
The inlet 46 is positioned at the front of the manifold 44 and extends between the sidewalls 52 and 54. In an alternative embodiment, the inlet may be positioned in the sidewalls 52 and 54. In one embodiment, the inlet 46 has a rectangular shape corresponding to the shape of the manifold 44. As such, the inlet 46 is as wide and tall as the manifold 44, allowing an increased area through which the cables 42 may enter the manifold 44. Alternatively, a front wall (not shown) may be provided that defines the inlet 46. As such, the inlet 46 is an opening in the front wall having a predetermined shape, such as a circular shape, an oval shape, or a rectangular shape. Optionally, a protective liner (not shown) may extend along the inlet 46 to protect the cables 42 from wear.
In one embodiment, bracket mounts 58 and 60 extend from the side walls 52 and 54, respectively, at the front of manifold 44. The bracket mounts 58 and 60 permit the manifold 44 to be loaded onto the corresponding support brackets 28 or 30. In one embodiment, the bracket mounts 58 and 60 abut a front facing surface 61 of the support brackets 28 and 30, respectively. Alternatively, the bracket mounts 58 and 60 include a hook end (not shown) that extends around the corresponding support brackets 28 or 30 to resist horizontal movement of manifold 44 away from the support brackets 28 and 30. Once each bracket mount 58 and 60 is positioned along the corresponding support bracket 28 and 30, the manifold 44 is secured to the support bracket 28 and 30 through any of several conventional fastening means, such as bolts, screws, welding, adhesive, hooks and the like. In the exemplary embodiment of
An outlet 66 extends through the top wall 48 and the back wall 56 of the manifold 44 for allowing access for the cables 42 to the patch panels 14. Optionally, the outlet 66 may only extend through one of the top wall 48 or the back wall 56. In one embodiment, the outlet 66 has a curvilinear shape, such that the outlet 66 is wider in the middle of the manifold top wall 48 as compared to the width near the manifold side walls 52 and 54. Accordingly, the mass of cables 42 are directed away from the side walls 52 and 54 at the outlet 66. In one embodiment, the shape of the outlet may correspond to the shape of the patch panels 14 such as for example, the arcuate shape illustrated in
The outlet 66 directs the multiport cables 42 to the rear side of the patch panels 14. As such, the multiport cables 42 extend along a common plane that extends from the front to the rear of the cable management system 10. Additionally, by directing the multiport cables 42 from the front of the equipment system 32 to the rear of the patch panels 14, the multiport cables 42 are directed away from the sides of the cable management system 10. Accordingly, the multiport cables 42 do not interfere with the cabling that may be connected to the front of the patch panels 14 and directed along the sides of the cable management system 10 by the wire managers 18.
Optionally, the patch panels 14 and wire managers 16 may be constructed in other non-orthogonal geometries other than a C-shape. For example, the non-orthogonal geometry may resemble other cylindrical shapes, such as a complete circle, a complete or partial oval, a complete or partial polygon, and the like.
In one embodiment, the patch panel 14 includes a body 80 having a base 82, side walls 84 and 86 and a front face 88. The patch panel 14 generally includes front and rear connectivity interfaces 90 and 92, respectively. The front connectivity interface 90 includes multiple connector modules (not shown) configured to interface with connectors (not shown), such as, for example, RJ-45 connectors, optical connectors, power connectors and the like. However, many other types of connectors may be substituted and utilized.
The patch panel 14 may include one or more circuit boards 94 mounted on the base 82. The circuit board 94 is generally semi-circular in shape to follow the curvature of the base 82. The circuit board 94 includes conductive signal paths provided thereon, such as traces or in a lead frame. The traces interconnect individual contacts within each connector module with a corresponding multiport connector 98 which is mounted on the circuit board 94. The patch panel 14 includes multiple multiport connectors 98 mounted on the circuit board 94. The multiport connectors 98 each include a receptacle 100 which is configured to receive a multiport plug 102 extending from an end of a corresponding multiport cable 42. The multiport cables 42 convey multiple independent data streams. The individual data streams from the connector modules are not merged with one another, but instead are grouped at receptacle 100 for a single plug 102 and cable 42 configured to convey multiple independent data streams. Examples of the receptacle 100 are RJ-21, D-Subminiature, MPO, SCSI connectors and the like. The multiport connectors 98 define the rear connectivity interface 92. Alternately, a wire or optical fiber may be directly terminated to the rear face of the connector modules through means of crimping, soldering, adhesives, insulation displacement termination, splicing, connectorization and the like.
The patch panels 14 join with each of the wire manager modules 20 and 22 at respective abutting side walls 84 and 86 on the patch panels 14, and 104 and 106 on the wire managers 18. The side walls 84 and 86 of the patch panels 14 and the side walls 104 and 106 of the wire managers 18 are oriented to abut against one another along radial axes, generally denoted by arrows C and D, which extend outward from a central cavity 108 of the cable management system 10. Additionally, the side walls of the patch panels 14 direct the multiport cables 42 towards the central cavity 108 of the cable management system 10 where the cables 42 are grouped and directed as a single cable mass. Specifically, the cables 42 extend downward through the cable management system 10 to the manifold 44. The cables 42 are directed through the manifold outlet 66, through the manifold 44, and through the manifold inlet 46 (
In one embodiment, the cable management system 10 includes a louvered cover 110. The cover 110 includes a base 112 and a side wall 114. In one embodiment, the cover 110 is positioned adjacent the central cavity 108. Specifically, the cover 110 extends parallel to the patch panels 14 along the rear portion of the patch panels 14 such that the cover is configured to provide cooling airflow to each of the patch panels 14 in the cable management system 10. The cover 110 is coupled to the brackets 28 and 30 by bracket supports 116. In one embodiment the bracket supports 116 are fabricated from a rigid material, such as metal or plastic, and extend from either side of the cover 110 to the brackets 28 and 30. The supports 116 extend a predetermined length 117 from the brackets 28 and 30 such that the cover does not interfere with the central cavity 108, and with the cables 42 positioned within the central cavity 108. In one embodiment, the supports 116 have a length 117 such that the cover 110 abuts the wire managers 18.
A multitude of vents 118 extend through a portion of the side wall 114. In one embodiment, the vents 118 are oriented on the portion of the side wall 114 that abuts the central cavity 108. The vents 118 pass airflow through the central cavity 108 of the cable management system 10. In one embodiment, the vents 118 direct airflow from the cover 110 into the central cavity 108. In another embodiment, the vents 118 direct airflow from the central cavity 108 into the cover 110.
A plurality of fans 120 are coupled to the base 112 of the cover 110. Alternatively, the fans 120 may be coupled to a top portion of the louvered cover 110. In another alternative embodiment, the fans may be coupled along the side wall 114. The fans 120 direct cooling airflow into the central cavity 108 to cool the electrical components therein, such as, for example, the cables 42, the multiport connectors 98, and the circuit boards 94. As such, the fans 120 channel airflow into the louvered cover 110, through the vents 118, and into the central cavity 108. Alternatively, the fans 120 may be configured to extract the hot air from the central cavity 108 in order to lower the temperature of the components therein. As such, the fans 120 pull airflow out of the louvered cover 110, wherein airflow is also pulled out of the central cavity 108 via the vents 118. Accordingly, the louvered cover 110 provides a cooling circuit for the components of the cable management system 10. Additionally, by being positioned adjacent the central cavity 108, the components do not interfere with the flow path of the cooling airflow, rather, the airflow is directed around the components, thereby cooling the components. In alternative embodiments, other thermal management devices may be utilized to cool the electrical components within the cable management system, such as, for example, fluid filled radiators.
A duct 126 extends from the bottom end 124 of the louvered cover 110. In one embodiment, a plurality of ducts 126 extend from the bottom end 124, and are in flow communication with corresponding fans 120 (
In an alternative embodiment, the manifold 44 is positioned directly above the system 32 such that the gap 70 is not included. Optionally, the duct 126 may be coupled directly to the manifold 44. As such, the airflow passing through the manifold 44 into the duct 126 cools the multiport cables 42 extending through the manifold 44.
In operation, the airflow channeled through the louvered cover 110 may be directed into the central cavity 108, as indicated by arrow E, or may be extracted from the central cavity 108, as indicated by arrow F. The airflow is directed into, or out of, the central cavity 108 via the vents 118. Excess airflow is directed through the top end 122 of the cover 110.
The above-described cable management system 10 provides a cost effective and reliable means for assembling multiport cables 42. Specifically, the cable management system 10 includes a manifold 44 that can be coupled to a frame between an equipment system 32 and the corresponding patch panels 14. The cables 42 are directed into an inlet 46 of the manifold 44 and out through an outlet 66 of the manifold 44. Accordingly, the cables 42 are directed directly from the front of the equipment system 32 to the back of the patch panels 14. Accordingly, the amount of cable mass and the complexity of the cable routing is reduced. Additionally, due to the increased heat associated with such cable management systems 10, a thermal management system including a louvered cover 110 and a plurality of fans 120 are coupled in flow communication with the central cavity 108 of the cable management system 10. As such, the components of the system 10 are cooled.
Exemplary embodiments of cable management systems 10 are described above in detail. The systems 10 are not limited to the specific embodiments described herein, but rather, components of each system 10 may be utilized independently and separately from other components described herein. For example, each system 10 component can also be used in combination with other system 10 components.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
