Description

CABLE MANAGEMENT SYSTEM

[0001] The subject matter herein relates generally to cable management systems and, more particularly, to a cable management system for use in equipment racks.

[0002] Standard equipment cabinets or racks, such as data communications racks, are typically used to house a number of electrical components, switches, control panels and patch panels. Due to demands for increased capabilities, the panels are designed for an increasing quantity of connections. Once the panels are installed into the rack, the associated wires and cables are connected to the panels. The higher density panels have more connectors and consequently, more or larger associated cabling. In order to properly set-up the equipment rack and properly maintain the connectors, the cables must be installed in an organized manner.

[0003] Numerous problems exist with current cable management structures. For example, current horizontal support cable mangers are not robust enough to handle the size and weight of multi-conductor cables. Additionally, current systems do not provide the necessary strain relief for the cable and connector, and the cables may not be properly located when secured. Current systems do not support vertical strain relief or the transition from the horizontal to the vertical cable manager, and the size of the system limits the flexibility for use in different size racks. Additionally, current systems may be rack specific which further limits applications.

[0004] The solution is provided by a cable management system for cable management in an equipment rack. The cable management system includes a support bracket having a body extending between a mounting end and a distal end. The mounting end is configured to attach to the equipment rack, and the body has a tie down slot configured to receive a cable tie down. A cable bar is coupled to the distal end of the support bracket, wherein the cable bar has a tie down slot configured to receive a cable tie down. [0005] The invention will now be described by way of example with reference to the accompanying drawings in which:

[0016] Figure 11 is a partial side perspective view of the cable management system and distribution assembly in accordance with another embodiment.

[0017] Figure 1 is a rear perspective view of a cable management system 100 having a plurality of cable support assemblies 102 mounted to a distribution assembly 104. In the illustrated embodiment, the distribution assembly 104 represents a switching network, however, the distribution assembly 104 is merely illustrative and the cable management system 100 may be used with other types of systems/components that distribute or interconnect cables. The cable management system 100 provides strain relief, cable organization, and mechanical stability. The cable management system 100 is a multi piece solution with variable mounting configurations that support both horizontal and vertical cable management combined into one system.

[0018] The distribution assembly 104 generally includes an equipment rack 106 and a plurality of patch panels 108 arranged in a stacked configuration. The patch panels 108 include electronic modules 110 having multiple connector ports 112. Cables 114 (shown in Figure 4) are connected to the connector ports 112 at a rear interface 116 of the patch panels 108. The cables 114 may be grouped together as cable bundles and are routed generally behind the patch panels 108. The cables 114 are managed by the cable management system 100. Each patch panel 108 also receives other cables (not shown) at a front interface 118 of the patch panel 108. The equipment rack 106 includes a pair of posts 120 that are joined by a top plate 122. The patch panels 108 extend between and are coupled to the posts 120.

[0019] The cable management system 100 includes at least one cable support assembly 102. The cable support assemblies 102 are attached to the posts 120 of the equipment rack 106. For example, the posts 120 include mounting holes 124 on the rear flange 126 and/or the front flange 128 thereof. The mounting holes 124 have a predetermined spacing therebetween such that the cable support assemblies 102 may be mounted to any vertical location. In an exemplary embodiment, the cable support assemblies 102 fit into 1 U height requirements.

[0020] The cable support assemblies 102 generally include a first support bracket 130, a second support bracket 132 and a cable bar 134 extending therebetween. More or fewer support brackets 130, 132 and/or cable bars 134 may be provided in alternative embodiments. The support brackets 130, 132 are adjustably mounted to the equipment rack 106 and generally extend horizontally and rearwardly from the rear of the equipment rack 106. For example, the support brackets 130, 132 are adjustably attached to the posts 120 of the equipment rack 106 at adjustable locations to accommodate the specific cable support layout required. In an exemplary embodiment, as will be described in further detail below, the support brackets 130, 132 provide for cable support within the distribution assembly 104. The horizontal cable bar 134 provides a horizontal span between the first and second support brackets 130, 132 to provide for cable support within the distribution assembly 104.

[0021] Figure 2 is an exploded front perspective view of one of the cable support assemblies 102 being mounted to the equipment rack 106. One patch panel 108 is shown mounted to the front flanges 128 of the posts 120. The cable support assembly 102 is mounted to the rear flanges 126 of the posts 120, and is substantially vertically aligned with the patch panel 108, however, the cable support assembly 102 may be mounted at any vertical position along the posts 120. Fasteners 140 are used to secure the support brackets 130, 132 to the posts 120 separate from the patch panel 108.

[0022] The first support bracket 130 includes a body 142 having a center section 144 extending between a mounting end 146 and a distal end 148. When coupled to the equipment rack 106, the distal end 148 is cantilevered from the equipment rack 106. The body 142 has a length 150 that is selected such that the distal end 148 is at a depth from the rear interface 116. Optionally, different support brackets 130 having different lengths 150 may be provided and used with the cable management system 100.

[0023] The center section 144 of the body 142 is defined by a straight side 152 and a sloped side 154 that both extend between the mounting end 146 and the distal end 148. In an exemplary embodiment, the center section 144 has an L-shaped cross section, wherein a flange or lip 156 is provided at the straight side 152 and extends generally inwardly. The lip 156 provides rigidity to the center section 144 and may reduce bending or rotation of the center section 144 when the support bracket 130 is placed under load. Optionally, the center section 144 may have a C-shaped cross-section with both the straight side 152 and the sloped side 154 having a flange or lip. The sloped side 154 is non-parallel with the straight side 152 and is generally converging toward the straight side 152 from the mounting end 146. As such, the center section 144 is wider at the mounting end 146 than at the distal end 148. In an exemplary embodiment, the support bracket 130 is mounted to the equipment rack 106 such that the straight side 152 defines a top side of the support bracket 130. In an alternative embodiment, the support bracket 130 is mounted to the equipment rack 106 such that the straight side 152 defines a bottom side of the support bracket 130. Such mounting options provide more flexibility in the location of the mounting of the support bracket 130. Additionally, particularly when closely spacing support brackets 130, the sloped nature of the sloped side 154 provides access or clearance between adjacent support brackets 130, particularly proximate the distal ends 148 for cables and/or a persons hand or tool to install or remove the cable bar 134.

[0024] In an exemplary embodiment, the center section 144 of the support bracket 130 includes a plurality of tie down slots 158. The tie down slots 158 are generally vertically oriented and are sized and shaped to receive cable tie downs 200 (shown in Figure 4) to position and/or secure the cables 114 to the support bracket 130. The tie down slots 158 are spaced apart from one another to define different tie down depths from the rear interface 116 of the patch panel 108. In an alternative embodiment, the tie down slots 158 may be oriented non- vertically, such as horizontally or at an angle between vertical and horizontal. The tie down slots 158 allow the cables 114 to be supported and organized along the vertical sides of the equipment rack 106 on the sides of the support bracket 130.

[0025] The first support bracket 130 includes a rack mounting tab 160 at the mounting end 146 and a rear attachment flange 162 at the distal end 148. The rack mounting tab 160 extends generally perpendicular from the body 142. The rack mounting tab 160 is generally outwardly flared. Tab holes 164 are provided in the rack mounting tab 160 and are aligned with the mounting holes 124 in the post 120. Optionally, the tab holes 164 may be vertically elongated such that the vertical position of the support bracket 130 may be adjusted, such as to align the tab holes 164 with the mounting holes 124. The fasteners 140 extend through the tab holes 164 and the mounting holes 124 to secure the support bracket 130 to the post 120.

[0026] The rear attachment flange 162 extends along the straight side 152 of the center section 144 proximate to the distal end 148. The rear attachment flange 162 extends generally perpendicular from the center section 144 and is generally inwardly flared. The cable bar 134 is attached to the rear attachment flange 162. In an exemplary embodiment, the rear attachment flange 162 includes a bracket opening 166 extending therethrough.

[0027] The second support bracket 132 is substantially similar to the first support bracket 130, and like components will hereinafter be designated with like reference numerals. In an exemplary embodiment, the second support bracket 132 is a mirror image of the first support bracket 130.

[0028] The cable bar 134 is mounted to the rear attachment flanges 162 of the support brackets 130, 132, such as by using fasteners 168. Figure 2 illustrates the cable bar 134 mounted in a first orientation or configuration. While the fasteners 168 are illustrated in Figure 2 as thumb screws, other types of fasteners may be used in alternative embodiments to securely couple the cable bar 134 to the support brackets 130, 132. For example, the fastener may be a rivet, a pin, a bolt, a clamp, a tie-down, and the like. The cable bar 134 is removably coupled to the support brackets 130, 132, such as by releasing or removing the fasteners 168. Alternatively, the cable bar 134 may be permanently coupled to the support brackets 130, 132, such as by welding. In one alternative embodiment, the cable bar 134, is integrally formed with at least one of the support brackets 130, 132.

[0029] The cable bar 134 has a generally L-shaped cross-section and includes a first leg 170 and a second leg 172 that extends generally perpendicularly from the first leg 170. The cable bar 134 extends between a first end 174 and a second end 176. In one orientation, the first end 174 is attached to the first support bracket 130 and the second end 176 is attached to the second support bracket 132. The cable bar 134 includes a first mounting flange 178 at the first end 174 and a second mounting flange 180 at the second end 176. The mounting flanges 178, 180 extend along both legs 170, 172. The first mounting flange 178 includes a first leg opening 182 through the first leg 170 and a second leg opening 184 through the second leg 172. Similarly, the second mounting flange 180 includes a first leg opening 186 through the first leg 170 and a second leg opening 188 (shown in Figure 3) through the second leg 172.

[0030] When assembled in the first orientation, as illustrated in Figure 2, the first leg opening 182 at the first end 174 is aligned with the bracket opening 166 in the first support bracket 130. The fastener 168 extends through the first leg opening 182 and the bracket opening 166 to securely couple the first end 174 of the cable bar 134 to the first support bracket 130. Similarly, in the first orientation, the first leg opening 186 at the second end 176 is aligned with the bracket opening 166 in the second support bracket 132. The fastener 168 extends through the first leg opening 186 and the bracket opening 166 to securely couple the second end 174 of the cable bar 134 to the second support bracket 132.

[0031 ] A plurality of tie down slots 196 extend through the first leg 170. The tie down slots 196 are elongated in the direction from the second leg 172 to an edge 198 of the first leg 170. The tie down slots 196 are sized and shaped to receive cable tie downs (shown in Figure 4) to position and/or secure the cables 1 14 to the cable bar 134. The tie down slots 196 are spaced apart from one another to define different tie down locations that are aligned with different areas of the rear interface 116 of the patch panel 108. The tie down slots 196 provide for using a tie down 200 (shown in Figure 4) to attach one or more cables 114 to provide strain relief, support and organization for the cables 114 and the cable bundles. In the illustrated embodiment, when the cable bar 134 is mounted to the support brackets 130, 132 in the first orientation, the tie down slots 196 are oriented generally horizontally along a horizontal plane defined by the first leg 170.

[0032] Figure 3 is an exploded front perspective view of the same cable support assembly 102 illustrated in Figure 2, but being assembled differently than in the embodiment shown in Figure 2. The cable support assembly 102 is attached to front flanges 128 of the posts 120. The same fasteners 140 are used to secure the patch panel 108 and the support brackets 130, 132. When assembled, the rear attachment flanges 162 of the support brackets 130, 132 are located at a different, shallower, depth from the rear interface 116 of the patch panel 108, as compared to the embodiment shown in Figure 2, as at least a portion of the patch panel 108 extends along the body 142.

[0033] The cable bar 134 is attached to the support brackets 130, 132 in a second orientation or configuration. The second orientation is generally flipped with respect to the first orientation such that the tie down slots 196 are oriented substantially vertically as opposed to horizontally as in the first orientation. In the second orientation, the first leg 170 is oriented generally vertically and the second leg 172 is oriented generally horizontally. In the second orientation, the first end 174 is attached to the second support bracket 132 and the second end 176 is attached to the first support bracket 130.

[0034] The cable bar 134 includes a longitudinal axis 190 extending along the first and second legs 170, 172. The first and second legs 170, 172 are parallel to the longitudinal axis 190. A first transverse axis 192 extends through the first leg 170 and is perpendicular to the longitudinal axis 190. The second leg 172 is parallel to the first transverse axis 192. A second transverse axis 194 extends through the second leg 172 and is perpendicular to the longitudinal axis 190 and the first transverse axis 192. The first leg 170 is parallel to the second transverse axis 194. To transition from the first orientation to the second orientation, the cable bar 134 may be rotated about the longitudinal axis 190 approximately 180 degrees and the cable bar 134 may be rotated about one of the transverse axes 192, 194 approximately 90 degrees to transition the cable bar 134 from the first orientation to the second orientation, and vice versa.

[0035] When assembled in the second orientation, as illustrated in Figure 3, the second leg opening 184 at the first end 174 is aligned with the bracket opening 166 in the second support bracket 132. The fastener 168 extends through the first leg opening 184 and the bracket opening 166 to securely couple the first end 174 of the cable bar 134 to the second support bracket 132. Similarly, in the second orientation, the second leg opening 188 at the second end 176 is aligned with the bracket opening 166 in the first support bracket 130. The fastener 168 extends through the second leg opening 188 and the bracket opening 166 to securely couple the second end 176 of the cable bar 134 to the first support bracket 130.

[0036] The leg openings 182, 184, 186 and 188 allow the cable bar 134 to be mounted to the support brackets 130, 132 in either the first orientation (shown in Figure 2) or in the second orientation (shown in Figure 3). For example, in the first orientation the first leg 170 is the horizontal leg and the second leg 172 is the vertical leg. In the second orientation, the first leg 170 is the vertical leg and the second leg 172 as the horizontal leg. Thus, the tie down slots 196 in the first leg 170 may be located on the top surface of the mounted horizontal cable bar 134 or the rear surface of the horizontal cable bar 134. The flexible mounting scheme of the cable bar 134 provides both horizontal and vertical strain relief and management and, provides both top and back attachment of the cables providing easy access to the electrical equipment or panels for installation and removal of the cables during replacement or trouble shooting. [0037] Each of the components of the cable support assemblies 102 may include features, such as plates, tags, or other means for labeling cables and cable bundles to provide further organization within the equipment rack.

[0038] Figure 4 is a top view of the cable management system 100 and equipment rack 106 with a plurality of cables 114 secured to the cable support assemblies 102. The cable bar 134 is coupled to the support brackets 130, 132 such that the first leg 170 and the tie down slots 196 are oriented horizontally. Some of the cables 114 are secured to the top of the cable bar 134, while some of the cables 114 are secured to the bottom of the cable bar 134. For example, tie downs 200 extend through the tie down slots 196 and wrap around the cables 114 to secure the cables against the cable bar 134. The tie downs 200 may be plastic strips that are self- securing, such as zip ties, tie wraps, straps, clips, and the like. Alternatively, the tie downs 200 may be a strap, such as of a cloth material, having a fastener at at least one of the ends, such as a hook and loop fastener. In the illustrated embodiment, some of the cables 114 are secured to the second support bracket 132 rather than the cable bar 134. Tie downs 200 are again used to extend through the tie down slots 158 (shown in Figure 2) to secure the cables 114 to the support bracket 132. Optionally, the cables 114 may be run along either the inside or the outside of the support bracket 132.

[0039] Figure 5 is a rear perspective view of one of the cable support assemblies 102 in a partially opened state. In an exemplary embodiment, the cable bar 134 may be moved to provide access to the rear interface 116 (shown in Figure 1) of the equipment rack 106 (shown in Figure 1). In one embodiment, the cable bar 134 may be rotated about either the first end 174 or the second end 176, such as by removing one of the fastener 168, such as the fastener securing the second end 176 to the second support bracket 132. Once the fastener 168 is released or removed, the cable bar 134 may be pivoted or rotated about the fastener 168 securing the first end 174 to the first support bracket 130. Once moved, the rear interface 1 16 may be accessed. In an alternative embodiment, rather than pivoting, the entire cable bar 134 may be removed from the support brackets 130, 132. For example, both fasteners 168 may be released or removed and then the cable bar 134 may be removed. Once removed, the rear interface 116 may be accessed.

[0040] In an exemplary embodiment, the leg openings 182 and 188 are elongated in the direction from the second leg 172 to the edge 198 of the first leg 170. Once one of the fasteners 168 is removed, to facilitate movement of the cable bar 134, the cable bar 134 is first moved or translated in a rearward direction, wherein the cable bar 134 is slid along the fastener 168. The position of the fastener 168 within the elongated opening 182 (shown in Figure 2) is changed. Such movement provides clearance between the first end 174 of the cable bar 134 and the distal end 148 of the support bracket 130. The clearance allows the cable bar 134 to be rotated about the fastener 168.

[0041] Figure 6 is a side view of two of the cable support assemblies 102 in different mounted orientations. The upper cable support assembly 102 is normally mounted to the equipment rack 106, while the lower cable support assembly 102 is reverse, or upside-down, mounted to the equipment rack 106. When normally mounted, the straight side 152 is the top of the support bracket 130 and the sloped side 154 is the bottom of the support bracket 130. When upside-down mounted, the sloped side 154 is the top of the support bracket 130 and the straight side 152 is the bottom of the support bracket 130.

[0042] The cable bars 134 are attached to the straight sides 152 of support brackets 130. By mounting the support brackets 130 in different mounted orientations, the vertical positions of the cable bars 134 can be controlled. For example, in the normally mounted position, the cable bar 134 is generally aligned with the top of the mounting end 146, whereas in the reverse mounted position, the cable bar 134 is generally aligned with the bottom of the mounting end 146. As such, the cable bars 134 may be further spaced from one another as compared to a situation in which both cable support assemblies 102 are mounted in the same orientation. Such mounting options provides more flexibility in the location of the supporting elements for the cables 114 (shown in Figure 4). [0043] Figure 7 illustrates an exemplary group of cable support assemblies 102. Figure 7 illustrates that different sized support brackets 130 may be provided. For example, the center sections 144 of the support brackets 130 may have different lengths 150. Figure 7 illustrates three different sized support brackets 130 having center section lengths 150 of, for example, six inches, nine inches, and twelve inches. However, support brackets 130 of any length may be used, including support brackets 130 having lengths longer than twelve inches or shorter than six inches. The variable length of the support brackets 130 provides for variable depths of the cable support assemblies 102 when used together and mounted to the equipment rack 106 (shown in Figure 1). For example, one cable support assembly 102 may have a support bracket 130 with a length 150 of six inches, cable support assembly 102 may have a support bracket 130 with a length 150 of nine inches and a further cable support assembly 102 may have a support bracket 130 with a length 150 of twelve inches. When used together, the cable management system 100 (shown in Figure 1) may have a tiered arrangement, some examples of which are shown in Figures 9-11.

[0044] Figure 8 is a side perspective view of a post support bar 210 for use with a four post equipment rack (not shown). The post support bar 210 mounts substantially horizontally between two posts within the four post equipment rack and may be mounted in any vertical location in standard equipment racks. In an exemplary embodiment, the post support bar 210 mounts between a front post and a back post of a four post equipment rack to provide post support and/or cable support on the sides of the equipment rack.

[0045] The post support bar 210 includes mounting flanges 212 at each end thereof and a spanning section 214 between the mounting flanges 212. The spanning section 214 has a C-shaped cross-section. The spanning section 214 includes a plurality of tie down slots 216 for placement of tie downs 200 (shown in Figure 4) to support cables 1 14 (shown in Figure 4). Optionally, the tie down slots 216 may be substantially vertically oriented. The post support bar 210 provides support and organization of vertical cable runs without impeding installation of the cable support assemblies 102 (shown in Figure 1) and additional cables 114. [0046] Figure 9 is a partial rear view of the cable management system 100 and equipment rack 106 with a plurality of cables 114 secured to the cable support assemblies 102. Figure 10 is a partial rear perspective view of the cable management system 100 and equipment rack 106 shown in Figure 9. In the illustrated embodiment of Figures 9 and 10, five cable bundles are shown, wherein each cable bundle includes more than one cable 114. The cable bundles are identified as cable bundles 220, 222, 224, 226 and 228.

[0047] In the illustrated embodiment of Figures 9 and 10, three cable support assemblies are shown. The cable support assemblies are identified as cable support assemblies 230, 232 and 234. Each cable support assembly 230, 232 and 234 is sized differently. For example, the first, or upper, cable support assembly 230 has support brackets with a length of six inches. The second, or middle, cable support assembly 232 has support brackets with a length of nine inches. The third, or lower, cable support assembly 234 has support brackets with a length of twelve inches. The cable support assemblies thus provide a tiered approach for cable management. The cable bars of the upper and middle cable support assemblies 230, 232 are in a first orientation such that the tie down slots 196 are horizontally oriented. The cable bar of the lower cable support assembly 234 is in a second orientation such that the tie down slots 196 are vertically oriented.

[0048] The first cable bundle 220 is secured to the cable bar of the lower cable support assembly 234 using a tie down 200. All of the cables 114 in the first cable bundle 220 extend along the outside of the cable bar. The first cable bundle 220 is also secured to the cable bar of the upper cable support assembly 230 using another tie down 200. Some of the cables 114 in the first cable bundle 220 extend along the top of the cable bar and some of the cables 114 in the first cable bundle 220 extend along the bottom of the cable bar.

[0049] The second cable bundle 222 is secured to the cable bar of the middle cable support assembly 232 using a tie down 200. All of the cables 114 in the second cable bundle 222 extend along the bottom of the cable bar. [0050] The third cable bundle 224 is secured to the cable bar of the lower cable support assembly 234 using a tie down 200. All of the cables 114 in the third cable bundle 224 extend along the outside of the cable bar. The third cable bundle 224 is also secured to the cable bar of the upper cable support assembly 230 using another tie down 200. Some of the cables 114 in the third cable bundle 224 extend along the top of the cable bar and some of the cables 114 in the third cable bundle 224 extend along the bottom of the cable bar. The fourth cable bundle 226 is secured in a similar manner as the third cable bundle 224.

[0051] The fifth cable bundle 228 is secured to the bracket support 130 of the lower cable support assembly 234 using a tie down 200. All of the cables 114 in the fifth cable bundle 228 extend along the outside of the bracket support 130. The fifth cable bundle 228 is also secured to the cable bar of the upper cable support assembly 230 using another tie down 200. All of the cables 114 in the fifth cable bundle 228 extend along the top of the cable bar.

[0052] The cable management system 100 thus provides strain relief, cable organization, and mechanical stability. The various mounting configurations of the cable tie downs 200 support both horizontal and vertical cable management combined into one system. The support brackets may be adjustably attached to the equipment rack 106 at adjustable locations to accommodate the specific cable support layout required.

[0053] Figure 11 is a partial side perspective view of the cable management system 100 and equipment rack 106 having a different arrangement of cable support assemblies 102 and cables 114 than the embodiment illustrated in Figures 9 and 10. In the illustrated embodiment of Figure 11, four cable bundles are shown, wherein each cable bundle includes more than one cable 114. The cable bundles are identified as cable bundles 240, 242, 244 and 246.

[0054] In the illustrated embodiment of Figures 11, four cable support assemblies are shown. The cable support assemblies are identified as cable support assemblies 250, 252, 254 and 256. The cable support assemblies 254 and 256 are sized the same as one another, but are sized differently than the cable support assemblies 250 and 252. For example, the first, or upper, cable support assembly 250 has support brackets with a length of six inches. The second, or upper-middle, cable support assembly 252 has support brackets with a length of nine inches. The third, or lower-middle, cable support assembly 254 and the fourth, or lower, cable support assembly 256 both have support brackets with a length of twelve inches. The cable support assemblies thus provide a tiered approach for cable management.

[0055] Each of the cable bundles 240, 242, 244 and 246 are secured to the support bracket 130 of the lower cable support assembly 256 using tie downs 200. The first and second cable bundles 240, 242 are both secured to the support bracket 130 of the lower-middle cable support assembly 254 using a common tie down 200.

[0056] The cable management system 100 thus provides strain relief, cable organization, and mechanical stability. The various mounting configurations of the cable ties 200 support both horizontal and vertical cable management combined into one system. The support brackets may be adjustably attached to the equipment rack 106 at adjustable locations to accommodate the specific cable support layout required.
