## Background
BACKGROUND OF THE INVENTION
The subject matter herein relates generally to connectivity management systems, and more particularly to a panel assembly for a connectivity management system.
Known connector assemblies exist having multiple receptacle connectors in a common housing, which provide a compact arrangement of such receptacle connectors. Such a connector assembly is useful to provide multiple connection ports. Accordingly, such a connector assembly is referred to as a multiple port connector assembly. The connector assemblies are typically used in data communication networks and are mounted within a frame or rack. The connector assemblies are typically mounted within a patch panel.
Problems arise due to the large number of cables that are connected within such systems. Cable management systems and connectivity management systems have been developed to address such problems. For example, in order to better operate large electrical networks, connectivity management systems have been developed to monitor connections between components within the network. The patch panels include sensor bars that are fixed to the patch panels and that monitor a connectivity status of the connector assemblies mounted within the patch panel.
Known connectivity management systems are not without disadvantages. For instance, the connectivity management systems are typically designed for one particular type of connector assembly and one particular type of patch cord. However, different electrical networks utilize different types of connector assemblies and different types of patch cords. A different connectivity management system is designed for the different networks and connectors associated with such networks. For example, a different patch panel is provided for each different type of network. The patch panel includes sensors that monitor the connectivity status of the various network components used with the patch panel.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front perspective view of a portion of a cable interconnect system 10 illustrating a panel assembly 11 having a panel 12 and a plurality of cassettes 20 mounted to the panel 12. A plug 14 is illustrated being connected to one of the cassettes 20 at a front mating interface 18 of the cassette 20. The cassette 20 includes an array of receptacles 16 for accepting or receiving one or more plugs 14. The array of receptacles 16 defines the front mating interface 18. The receptacles 16 may be of any particular type configured to receive plugs 14 of a corresponding type. For example, in an exemplary embodiment, the receptacles 16 and plugs 14 have metal contacts that transmit data and/or power. In another exemplary embodiment, the receptacle and plug are of the fiber-optic type.
The cable interconnect system 10 is utilized to interconnect various equipment, components and/or devices to one another. FIG. 1 schematically illustrates a first device 60 that is configured to be connected to the cassette 20 via a cable 62. The modular plug 14 is attached to the end of the cable 62. FIG. 1 also illustrates a second device 64 connected to the cassette 20 via a cable 66. The cassette 20 interconnects the first and second devices 60, 64. In an exemplary embodiment, the first device 60 may be a computer located remote from the cassette 20 or a wall jack in another room for receiving an Ethernet cord attached to a computer or other device in that room. Alternatively, the in first device 60 may be another panel located on the same equipment rack or in the same equipment room. The second device 64 may be a network switch. Optionally, the second device 64 may be mounted to the support structure 68. Alternatively, the second device 64 may be a computer or wall jack located remote from the cassette 20. The first and/or second devices 62, 64 may be located in the vicinity of the cassette 20, such as in the same equipment room, or alternatively, may be located remote from the cassette 20.
The cable interconnect system 10 includes a support structure 68, a portion of which is illustrated in FIG. 1, for supporting the panel 12 and the cassettes 20. For example, the support structure 68 may be an equipment rack of a network system. In an exemplary embodiment, the panel 12 is a patch panel that is mounted to the equipment rack. In alternative embodiments, rather than a patch panel, the panel 12 may be another type of network component, used with a network system that supports cassettes 20 and/or other connector, assemblies, such as interface modules, stacked jacks, or other individual modular jacks. For example, the panel 12 may be a wall or other structural element of a component. It is noted that the cable interconnect system 10 illustrated in FIG. 1 is merely illustrative of an exemplary system or component for interconnecting communication cables.
The cable interconnect system 10 utilizes a connectivity management system 70 for monitoring and/or managing the connectivity of the cable interconnect system 10. For example, the connectivity management system 70 determines a connectivity status of each of the receptacles 16. The connectivity management system 70 includes an analyzer 72 for analyzing the connectivity of the components within the cable interconnect system 10. The analyzer 72 may be any type of electronic component that monitors connectivity status of the various components of the cable interconnect system 10.
In an exemplary embodiment, the plug 14 includes a network sensor probe 74 used to indicate connectivity, as described in further detail below. The sensor probe 74 represents an additional contact associated with the plug 14. In the cable interconnect system 10, the cables 62 may be routed between various ones of the panels 12 or other network components. The plugs 14 with the sensor probes 74 may come from other equipment in the cable interconnect system 10.
The cassettes 20 include connectivity sensors 76 at the mating interface thereof for interfacing with the sensor probes 74 when the plugs 14 are received in the receptacles 16. The connectivity sensors 76 are used to indicate connectivity, such as by sensing the connectivity status of the sensor probes 74 and sending signals relating to the connectivity status of the sensor probes 74 to the analyzer 72, such as via connectivity cables 78 that interconnect the cassettes 20 and the analyzer 72. The panel 12, cassettes 20 and connectivity sensors 76 together define the panel assembly 11 that may be packaged together or sold separately. For example, the panel 12 and connectivity sensors 76 may be sold separately as a kit from the cassettes 20. Different types of cassettes 20 may be used with the same panel 12 and connectivity sensors 76. For example, different cassettes 20 having different mating interfaces may be assembled with the panel 12. The connectivity sensors 76 may be removed to remove a particular cassette 20 and replace the cassette 20 with a different cassette 20. The connectivity sensor 76 may then be re-assembled with the cassette 20 and panel 12.
Connectivity cables 78 are cables that form part of the connectivity management system 70 and generally interconnect the cassettes 20 with the analyzer 72. Connectivity cables 78 extend from the rear of the cassettes 20 as opposed to the communication babies 62 which extend from the front of the cassettes 20. Communication cables may also extend from the rear of the cassettes 20. The cables 62 are part of the cable interconnect system 10 and are used to transmit data between components of the cable interconnect system 10, as opposed to the connectivity management system 70.
The analyzer 72 determines the connectivity status of the receptacles 16 within the cable interconnect system 10 by determining which plug 14 is connected to which receptacle 16 and/or where each patch cord or cable 62 is routed within the cable interconnect system 10. The analyzer 72 may also determine the connectivity status of the receptacles 16 by determining if data or power is being transmitted through the particular receptacle 16. Optionally, the analyzer 72 may be mounted to a rack or other support structure of the cable interconnect system 10. Alternatively, the analyzer 72 may be positioned remote from the rack and the network panels 12. Data relating to the connectivity or interconnection of the patch cords or cables 62 is transmitted to the analyzer 72 by the connectivity tables 78.
In an exemplary embodiment, the analyzer 72 is interconnected with a computing device 80 by an Ethernet connection or another connection, such as a direct connection by a cable connector. The connectivity data is gathered by connectivity sensors 76 that sense when the plugs 14 are mated with the receptacles 16. The connectivity data gathered by the analyzer 72 may be transmitted to the computing device 80 and then viewed, stored and/or manipulated by the computing device 80. Alternatively, the analyzer 72 may store and/or manipulate the connectivity data. Optionally, the analyzer 72 and the computing device 80 may be one device. Optionally, multiple analyzers 72 may be connected to the computing device 80. The analyzer 72 may be a general purpose computer. The analyzer 72 may include a processor, memory, software, hardware and the like. The analyzer 72 may be housed within the equipment room, or alternatively, may be housed elsewhere.
FIG. 2 is an exploded front perspective view of the panel assembly 11 illustrating a portion of the panel 12 and exemplary cassettes 120 for mounting to the panel 12. Only one side of the panel 12 and two of the cassettes 120 are illustrated. The connectivity sensor 76 is arranged for mating to the 120. In an exemplary embodiment, the cassettes 120 may be similar to the cassettes described in U.S. application Ser. No. 12/395,049 filed on Feb. 27, 2009 titled CASSETTE FOR USE WITHIN A CONNECTIVITY MANAGEMENT SYSTEM, the complete subject matter of which is hereby incorporated by reference in its entirety.
The cassettes 120 are configured to be mounted within openings 122 of the panel 12. The openings 122 are defined by a perimeter wall 124. In an exemplary embodiment, the panel 12 includes a plurality of openings 122 for receiving a plurality of cassettes 120. The panel 12 includes a planar front surface 125 and a planar rear surface 123 opposite the front surface 125. The cassettes 20 are loaded into the openings 122 from the front and are mounted against the front surface 125. The panel 12 includes mounting tabs 126 on the sides thereof for mounting to the support structure 68 (shown in FIG. 1). For example, the mounting tabs 126 may be provided at the sides of the panel 12 for mounting to a standard equipment rack or other cabinet system. Optionally, the panel 12 and mounting tabs 126 fit into 1 U height requirements. The panel 12 includes top and bottom rails 127 extending rearward from the rear surface 123. The rails 127 provide rigidity to the panel 12. In an exemplary embodiment, the panel 12 includes one or more brackets 129 extending rearward from the rear surface 123. The brackets 129 may be integrally formed with the panel 12. Alternatively, the brackets 129 may be secured, to the panel 12, such as by welding the brackets 129 to the panel 12.
The cassette 120 includes a shell 128 defining an outer perimeter of the cassette 120. In an exemplary embodiment, the shell 128 is a two piece design having a housing 130 and a cover 132 that may be coupled to the housing 130. The housing 130 and the cover 132 may have similar dimensions (e.g. height and width) to nest with one another to define a smooth outer surface. The housing 130 and the cover 132 may also have similar lengths, such that the housing 130 and the cover 132 mate approximately in the middle of the shell 128. Alternatively, the housing 130 may define substantially all of the shell 128 and the cover 132 may be substantially flat and be coupled to an end of the housing 130. Other alternative embodiments may not include the cover 132.
The shell 128 includes a front 134 and a rear 136 with the housing 130 at the front 134 and the cover 132 at the rear 136. The cassette 120 has a front mating interface 138 defined at the front 134. The cassette 120 has a rear mating interface 140 defined at the rear 136. The front mating interface 138 is defined by the structure of the housing 130, a plurality of plug cavities 142 formed in the housing 130 for receiving plugs, such as the modular plugs 14 (shown in FIG. 1), as well as communication modules 144 arranged within the shell 128 for mating with the plugs. The plug cavities 142 define receptacles that receive the plugs. The communication modules 144 are configured to be directly electrically connected to the plugs when the plugs are loaded into the plug cavities 142. The communication modules 144 transmit signals through the cassette 120. The plug cavities 142 and communication modules 144 cooperate to define a particular mating interface configured to receive a certain type of plug. In the illustrated embodiment, the plug cavities 142 and communication modules 144 are configured to receive an 8 position, 8 contact (8P8C) type of plug, such as an RJ-45 plug or another copper-based modular plug type of connector. Alternatively, the plug cavities 142 and communication modules 144 may be configured to receive different types of plugs, such as fiber-optic type of plugs. In an exemplary embodiment, the plug cavities 142 are arranged in a stacked configuration in a first row and a second row. A plurality of plug cavities 142 are arranged in each of the first and second rows.
The cassette 120 includes latch members 148 on one or more sides of the cassette 120 for securing the cassette 120 to the panel 12. The latch members 148 may be held close to the sides of the cassette 120 to maintain a smaller form factor. Alternative mounting means may be utilized in alternative embodiments. The latch members 148 may be separately provided from the housing 130 and/or the cover 132. Alternatively, the latch members 148 may be integrally formed with the housing 130 and/or the cover 132. The latch members 148 may additionally be used to couple the housing 130 and the cover 132 together.
During assembly, the cassettes 120 are loaded into the openings 122 of the panel 12 from the front of the panel 12 in a loading direction. The outer perimeter of the cassette 120 may be substantially similar to the size and shape of the perimeter walls 124 defining the openings 122 such that the cassette 120 fits snugly within the openings 122. The latch members 148 are used to secure the cassettes 120 to the panel 12. In an exemplary embodiment, the cassettes 120 include a front flange 150 at the front 134 of the shell 128. The flange 150 has a rear engagement surface 152 that engages the front surface 125 of the panel 12 when the cassette 120 is loaded into the opening 122. The latch members 148 engage the rear surface 123 of the panel 12 to capture the panel between latch members 148 and the rear engagement surface 152.
The connectivity sensor 76 is coupled to the cassettes 120. In an exemplary embodiment, the connectivity sensor 76 is coupled to the front 134 of the shell 128 generally between rows of the plug cavities 142. The connectivity sensor 76 is used to monitor a connectivity status of the various communication modules 144 of the cassette 120, such as by sensing the sensor probes 74 (shown in FIG. 1) of the plugs 14 when the plugs 14 are received the plug cavities 142. Optionally, the connectivity sensor 76 is coupled to a pair of cassettes 120 such that the connectivity sensor 76 determines the connectivity status of more than one cassette 120. Alternatively, the connectivity sensor 76 may be configured to be coupled to more or less than two cassettes 120. The connectivity sensor 76 is coupled to the cassettes 120 using fasteners 154. In an exemplary embodiment, spacers 156 may be attached to the cassettes 120. The spacers 156 define a mounting surface for the connectivity sensor 76. The spacers 156 position the mounting surface flush with the front 134 of the shell 128.
The connectivity sensor 76 includes a circuit board 158 having a plurality of sensor pads 160 arranged on a front side 162 of the connectivity sensor 76. The connectivity sensor 76 is mounted to the cassettes 120 such that a rear side 164 of the connectivity sensor 76 generally faces and/or engages the front 134 of the shell 128. The connectivity sensor 76 is mounted to the shell 128 such that the sensor pads 160 are aligned with corresponding plug cavities 142. For example, some of the sensor pads 160 may be arranged below one row the plug cavities 142, and some of the sensor pads 160 may be arranged above another row of the plug cavities 142. Optionally, an equal number of sensor pads 160 and plug cavities 142 are provided. In an exemplary embodiment, the connectivity sensor 76 includes a hub 166 and fingers 168 that extend in opposite directions from the hub 166. The sensor pads 160 are arranged on the fingers 168. The connectivity sensor 76 is coupled to the cassettes 120 such that the hub 166 is positioned in line with the space between the cassettes 120 when the cassettes 120 are mounted to the panel 12.
In an exemplary embodiment, the hub 166 is aligned with a window 170 in the panel 12. The connectivity sensor 76 includes a connectivity sensor connector 172 (shown in FIG. 3) extending from the rear side 164 of the circuit board 158. The connectivity sensor connector 172 is configured to be received within the window 170 when the cassettes 120 are mounted to the panel 12. A cable assembly 174 is connected to the connectivity sensor 76. For example, the cable assembly 174 is mated With the connectivity sensor connector 172. The cable assembly 174 may also be connected to a mating connector 182 (shown in FIG. 3) for mating to the sensor connector 172 and an I/O connector 184 (shown in FIG. 3) associated with the connectivity cable 78 (shown in FIG. 1) such that data from the connectivity sensor 76 may be transmitted to the connectivity cable 78 via the cable assembly 174. The cable assembly 174 may be coupled to the bracket 129 and thus held by the panel 12.
FIG. 3 is an exploded rear perspective view of the panel assembly 11 illustrating a portion of the panel 12 and the cassettes 120 showing the rear mating interface 140 of the cassette 120. The cassettes 120 include connector modules 180 defining portions of the rear mating interface 140. The connector modules 180 are electrically connected to the communication modules 144 (shown in FIG. 2). In the illustrated embodiment, the connector modules 180 are represented by RJ-21 type connectors, however, it is realized that other types of connectors may be used rather than RJ-21 type of connectors. For example, in alternative embodiments, the connector modules 180 may be another type of copper-based modular connectors, fiber optic connectors or other types of connectors, such as eSATA connectors, HDMI connectors, USB connectors, FireWire connectors, and the like.
As will be described in further detail below, the connector modules 180 are high density connectors, that is, each connector module 180 is electrically connected to more than one of the communication modules 144 (shown in FIG. 2) to allow communication between multiple plugs and the cable connector that mates with the connector module 180. The connector modules 180 are electrically connected to more than one communication module 144 to reduce the number of cable assemblies that interface with the rear of the cassette 120. It is realized that more or less than two connector modules 180 may be provided in alternative embodiments.
The connectivity sensor connector 172 extends from the rear side 164 of the connectivity sensor 76. The cable assembly 174 includes a mating connector 182 that mates with the connectivity sensor connector 172. The cable assembly 174 also includes an input/output (I/O) connector 184. A wire harness 186 extends between the mating connector 182 and the I/O connector 184. The I/O connector 184 is configured to be mounted to the bracket 129 using fasteners 188. The wire harness 186 and mating connector 182 extend forward from the I/O connector 184 to mate with the connectivity sensor connector 172, which extends through the window 170 in the panel 12. The window 170 is arranged between adjacent openings 122 in the panel 12. The I/O connector 184 is held by the bracket 129 for mating with a corresponding connector of the connectivity cable 78 (shown in FIG. 1). Data is communicated between the connectivity sensor 76 and the connectivity cable 78 by the cable assembly 174.
FIG. 4 is a front perspective, partial cutaway view of the cassette 120 illustrating a contact subassembly 200 of the cassette 120. The contact subassembly 200 includes the communication modules 144 and the connector modules 180.

In the illustrated embodiment, the contact subassembly 200 includes a circuit board 202 and an electrical connector 204 mounted to the circuit board 202. In an exemplary embodiment, the electrical connector 204 is a card edge connector. The communication modules 144 each include a contact support 206 and a plurality of contacts 208 arranged as a contact set extending from a front side of the circuit board 202. The contact supports 206 are positioned in close proximity to a corresponding set of the contacts 208. Each contact support 206 supports the contacts 208 of a different contact set.
The contacts 208 are electrically connected to the circuit board 202 and are electrically connected to the electrical connector 204 via the circuit board 202. Each contact set defines a different communication module 144. Optionally, the circuit board 202 may form part of the communication module 144, such that each of the communication modules 144 are linked together by a common circuit board 202. Alternatively, individual circuit boards 202 associated with each of the communication modules 144 may be provided and held within the shell 128 separate from the other circuit boards 202 and corresponding communication modules 144.
In the illustrated embodiment, each communication module 144 includes eight contacts 208 arranged as a contact array. The contacts 208 constitute a contact array that is configured to mate with plug contacts of an RJ-45 modular plug. The contacts 208 may have a different configuration for mating with a different type of plug in alternative embodiments.
During assembly, the contact subassembly 200 is loaded into the shell 128 such that the communication modules 144 are loaded into corresponding plug cavities 142. For example, the contact supports 206 and the contacts 208 are loaded into corresponding plug cavities 142. In an exemplary embodiment, a portion of the housing 130 extends between adjacent contact supports 206. For example, the housing 130 may include interior walls 210 that define the individual plug cavities 142. The interior walls 210 are positioned between adjacent communication modules 144 within each of the rows. The interior walls 210 are also positioned between the two rows such that the interior walls 210 are positioned between adjacent communication modules 144 within each column.
The cassette 120 includes an interface connector assembly 212 that includes the connector modules 180. The interface connector assembly 212 is configured to be mated with the electrical connector 204. In an exemplary embodiment, the interface connector assembly 212 includes a circuit board 214. The connector modules 180 are mounted to a side surface of the circuit board 214. An edge of the circuit board 214 is plugged into the electrical connector 204.
In an exemplary embodiment, the circuit board 202 is arranged generally perpendicular to the loading direction of the plugs into the plug cavities 142. The circuit board 202 is positioned generally behind the contacts 208, such as between the contacts 208 and the rear 136 of the shell 128. The circuit board 202 substantially covers the rear of each of the plug cavities 142 when the connector subassembly 200 is loaded into the shell 128.
FIG. 5 is a rear partial sectional view of an alternative cassette 220 for the cable interconnect system 10 (shown in FIG. 1). The cassette 220 is similar to the cassette 120 (shown in FIG. 2) in some respects, however the cassette 220 includes a different rear mating interface 222. The cassette 220 may be used in place of the cassette 120. For example, the cassette 220 has similar dimensions as the cassette 120 such that the cassette 220 may be loaded into the panel 12 (shown in FIG. 1). The connectivity sensor 76 (shown in FIG. 1) may be coupled to the cassette 220 and used to monitor a connectivity status of the cassette 220.
The cassette 220 includes a front mating interface 224 that is similar to the cassette 120. The cassette 220 includes a contact subassembly 226 having a circuit board 228 and a plurality of communication modules 230 extending from the circuit board 228 into plug cavities 232 at the front mating interface 224. The contact subassembly 226 includes an electrical connector 234 extending from circuit board 228.
The cassette 220 includes a plurality of connector modules 236 at the rear mating interface 222. The connector modules 236 are electrically connected to the communication modules 230. Data and/or power may be transmitted between the communication modules 230 and corresponding ones of the connector modules 236. In an exemplary embodiment, the cassette 220 includes an interface connector assembly 238 that includes a circuit board 240. The connector modules 236 are connected to the circuit board 240. The interface connector assembly 238 may be substantially similar to the contact subassembly 226. For example, an equal number of communication modules 230 and connector modules 236 may be provided. The communication modules 230 and the connector modules 236 may be connected to one another in a one-to-one relationship. The communication modules 230 and the connector modules 236 may be configured to receive plugs of the same type, for example, both may receive an RJ-45 plug or another copper-based modular plug type of connector. The interface connector assembly 238 includes an electrical connector 242. The electrical connector 242 may be connected to the electrical connector 234 of the contact subassembly 226.
In the illustrated embodiment, both electrical connectors 234, 242 represent card edge connectors. A circuit board 244 is plugged into both electrical connectors 234, 242, where data is transmitted across the circuit board 244 between the electrical connectors 234, 242. In alternative embodiment, the electrical connectors 234, 242 may be directly connected to one another.

The communication modules 426 include ferrules 442 for mating with the fiber-optic plugs.
With reference back to the Figures generally, the cable interconnect system 10 is modular in design to accommodate interconnecting components of different types of communication networks. For example, the panel 12 is configured to receive each of the various types of cassettes 20, 120, 220, 320, 420. For example, the outer perimeters of the cassettes may be substantially identical such that each of the cassettes wit into the openings 122 in the panel 12. As such, different mating interfaces may be presented at the panel for interconnecting different types of plugs and corresponding components of the networks. For example, the mating interfaces may be either copper based or fiber-optic based for receiving corresponding copper or fiber-optic plugs. The front mating interface may be the same as the rear mating interface, or alternatively, may be different than the rear mating interface. Additionally, different types of cassettes may be provided within the same panel 12. For example, a cassette having an RJ-45 type mating interface may be placed in the panel 12 next to a cassette having a quad type mating interface and/or a fiber-optic type mating interface. The cassettes may be removed and replaced with different types of cassettes, such as when the network system is being upgraded to utilize a different type of network cable or patch cable.
In the panel assembly 11, each of the cassettes 20, 120, 1220, 320, 420 are designed to mate with the connectivity sensor 76. The plug cavities of the cassettes are arranged in a similar or identical position irrespective of the type of cassette, such that the sensor pads 160 are properly positioned for mating with the plugs loaded into the plug cavities. As such, the same connectivity sensor 76 may be coupled to a cassette having an RJ-45 type mating interface, a cassette having a quad type mating interface or a cassette having, a fiber-optic type mating interface, or a cassette having another type of mating interface. The corresponding plugs (e.g. RJ-45 plug, quad plug or fiber-optic plug) include the sensor probe 74 that interfaces with the connectivity sensor 76. In this manner, the same connectivity sensor 76 is configured to sense a connectivity status of an RJ-45 plug, quad plug, fiber-optic plug, or other type of plug if another type of mating interface is provided. The plug 14 illustrated in FIG. 1 is representative of a plug used within a connectivity management system and may have any particular type of mating interface, be it an RJ-45 type mating interface, a quad type mating interface, a fiber optic type mating interface, or another type of mating interface. The analyzer 72 is capable of determining the type of signal being transmitted through the connectivity management system. The connectivity sensor 76 is easily removed from the respective cassette or cassettes and attached to different cassette that replaces the removed cassette.
