Cable management apparatus

[0001] 1. Field of the Invention

[0002] The present invention relates to an accessory of a server cabinet, and more particularly to a cable management apparatus attached to a server cabinet to manage the cables connected to a server.

[0003] 2. Description of Related Art

[0004] Generally, a server is installed in a cabinet via a pair of rail assemblies. A cable management apparatus is attached to the cabinet behind the server to manage the cables of the server to ensure that the cables are well ordered. The cable management apparatus generally includes a first supporting arm pivotably connected with a second supporting arm. The first and second supporting arms are attached to a rail assembly, and can rotate relative to each other when the server moves with the rail assemblies. But, when the server stays stationary, the first and second supporting arms can not rotate any more and block the access to the rear part of the sever.

[0005] Because of the existence of the above cable management apparatus, maintenance of the components behind the server such as power supply modules becomes inconvenient. The cable management apparatus must be detached from the cabinet to provide access for the maintenance.

[0006] What is desired, therefore, is a cable management apparatus that facilitates the maintenance of servers.

[0013] Referring to FIGS. 1, 2 and 4, a cable management apparatus in accordance with a first embodiment of the present invention is attached between a first rail assembly 80 and a second rail assembly 90, for managing cables 110 extending from a rear end of a server 100. The cable management apparatus includes a first supporting arm 10, a second supporting arm 20, a connecting member 30, a plurality of cable retainers 40, a first locking member 50, a second locking member 60, and a supporting member 70.

[0014] A rear end of the first rail assembly 80 defines a fixing hole 81 (see FIG. 5).

[0015] The first supporting arm 10 is approximately L-shaped, and includes a pole-shaped supporting portion 11, and a pivot portion 12 vertically extending from a first end of the supporting portion 11.

[0016] The second supporting arm 20 is approximately L-shaped, and includes a pole-shaped supporting portion 21, a pivot portion 22 vertically extending from a first end of the supporting portion 21, and a threaded portion 23 defined at a second end of the supporting portion 21.

[0017] The connecting member 30 includes a first connecting part 31 and a second connecting part 32. The first connecting part 31 includes a tube 313, a discoid-shaped hook portion 311 extending from an end of the tube 313, and a plurality of circularly distributed hooks 312 vertically extending from a circumference of a bottom of the hook portion 311. The tube 313 defines an axial hole 3132 therein. The second connecting part 32 includes a fixing pole 323, a discoid-shaped receiving portion 321 extending from an end of the fixing pole 323, and a blocking portion 324 radially extending outward from the receiving portion 321. The receiving portion 321 defines a stepped hole in a middle thereof. The other end of the fixing pole 323 axially defines a threaded hole 3232, corresponding to the threaded portion 23 of the second supporting arm 20.

[0018] Each cable retainer 40 may be formed by a wire bent into a U-shape. Distal ends 41 thereof are coiled and in axial alignment to receive a corresponding pole-shape supporting portion 11, 21 therethrough. The middle portion is bent toward the coiled ends 41 to form a hook like structure.

[0019] The first locking member 50 is approximately L-shaped, and includes an attaching portion and an extending portion vertically bent from one end of the attaching portion. A pivot part 51 is formed at a distal end of the extending portion.

[0020] The second locking member 60 includes an attaching portion, an extending portion vertically bent from one end of the attaching portion, and an elastic part 62 vertically bent from a distal end of the extending portion. A pivot part 61 is formed at an outer surface of the extending portion. Two cutouts 621 are respectively defined at opposite sides of the free end of the elastic part 62.

[0021] The supporting member 70 includes a supporting portion 71, a protrusion 72 extending outward from one end of the supporting portion 71, and a fixing portion 73 vertically bent from the other end of the supporting portion 71. The supporting portion 71 defines a fixing hole 74 adjacent the fixing portion 73. The fixing hole 74 includes a greater section and a smaller section communicating with the greater section.

[0022] Referring also to FIGS. 3 to 5, in assembly, the hooks 312 of the first connecting part 31 of the connecting member 30 is extended into the stepped hole 322 of the second connecting part 32 from the smaller hole of the stepped hole 322, and engaged with the step of the stepped hole 322. The first connecting part 31 is rotationally mounted to the second connecting part 32. The cable retainers 40 are positioned on the tube 313 of the first connecting part 31, the supporting portion 11 of the first supporting arm 10, or the supporting portion 21 of the second supporting arm 20, via their coiled ends 41. The cable 110 can be retained by the cable retainers 40. The supporting portion 11 of the first supporting arm 10 is slidably received in the axial hole 3132 of the tube 313 of the first connecting part 31, and the threaded portion 23 of the second supporting arm 20 is screwed into the threaded hole 3232 of the fixing pole 323 of the second connecting part 32 of the connecting member 30. The pivot portion 12 of the first supporting arm 10 and the pivot portion 22 of the second supporting arm 20 are respectively rotationally received in the pivot part 51 of the first locking member 50 and the pivot part 61 of the second locking member 60. The attaching portions of the first locking member 50 and the second locking member 60 are respectively fixed to rear ends of an inner rail and an outer rail of the second rail assembly 90. The protrusion 72 of the supporting member 70 is engaged in the fixing hole 81 of the first rail assembly 80. The fixing portion 73 of the supporting member 70 is inserted into an inner side of the outer rail of the second rail assembly 90. The elastic part 62 of the second locking member 60 is elastically deformed and passes through the greater section of the fixing hole 74 of the supporting member 70. The elastic part 62 of the second locking member 60 restores and moves into the smaller section of the fixing hole 74, and the cutouts 621 of the elastic part 62 are engaged with opposite edges of the smaller section of the fixing hole 74.

[0023] When the server 100 is completely accommodated in the cabinet, a top of the supporting portion 71 of the supporting member 70 supports the blocking portion 324 of the second connecting part 32 of the connecting member 30, to prevent the cable management apparatus from damage because of supporting heavy cables 110 for a long time.

[0024] When the server is moved forwards on the rail assemblies 80, 90, the cables 110 are supported by the cable retainers 40 and the first supporting arm 10 rotates relative to the second supporting arm 20. The cables 110 also supplies a force to prevent the supporting portion 11 of the first supporting arm 10 from sliding in the tube 313 of the first connecting part 31 of the connecting member 30. The blocking portion 324 is moved off of the supporting member 70. The cables 110 are maintained in a well ordered manner such that when the server is pushed back, the cables 110 do not get in the way of the server progress.

[0025] When components of the server 100 need to be maintenanced, the elastic part 62 of the second locking member 60 is moved into the greater section of the fixing hole 74 of the supporting member 70 against its elasticity. The fixing portion 73 of the supporting member 70 is drawn out of the outer rail of the second rail assembly 90, and the protrusion 72 of the supporting member 70 is disengaged from the fixing hole 81 of the first rail assembly 80 to detach the supporting member 70. The pivot portion 12 of the first supporting arm 10 and the pivot portion 22 of the second supporting arm 20 are respectively pivoted in the pivot part 51 of the first locking member 50 and the pivot part 61 of the second locking member 60. The first supporting arm 10 and the second supporting arm 20 can move toward the second rail assembly 90. The supporting portion 11 of the first supporting arm 10 slides in the tube 313 of the first connecting part 31 of the connecting member 30, until the first supporting arm 10 and the second supporting arm 20 are juxtaposed, and located beside the second rail assembly 90 to leave a space for the technicians to maintain the components of the server 100. Thus, the relative lengths of two sides the respective triangle can be altered allowing easy service of the servers.

[0026] Referring also to FIGS. 6 and 7, a cable management apparatus in accordance with a second embodiment of the present invention is similar to that of the first embodiment. The cable management apparatus of this embodiment includes a first supporting arm 10a, a second supporting arm 20a, and a connecting member 30a. The connecting member 30a is a helical spring, and both ends of the helical spring are fixed to the corresponding ends of the first supporting arm 10a and the second supporting arm 20a. When components of the server 100 need to be maintenanced. In virtue of the flexibility of the connecting member 30a, the pivot portions of the first supporting arm 10a and the second supporting arm 20a are respectively pivoted in the pivot part 51 of the first locking member 50 and the pivot part 61 of the second locking member 60, until the first and the second supporting arms 10a, 20a are juxtaposed, and located beside the second rail assembly 90, to leave a space for the technicians to maintain the components of the server 100. Thus, the relative lengths of two sides the respective triangle can be altered allowing easy service of the servers.
