BACKGROUND
1. Technical Field
The present disclosure relates to cable management and, more particularly, to a cable management apparatus for a rack-mounted device.
2. Description of the Related Art
Commonly used component racks often include a pair of opposing sides to which telescoping slide assemblies are connected for slidable support of electronic devices, such as servers. Typically, multiple devices are often disposed at different vertically spaced levels in the equipment rack, usually closely adjacent to each other. Cables extend from the electronic devices for connection outside the equipment rack.
A cable management apparatus is provided for supporting cables of each of the electronic devices in the rack. The cable management apparatus often includes at least two arms pivotally connected end to end. Opposite free ends of the cable management apparatus are respectively attached to a stationary rail and a movable rail of one of the slide assemblies. Accordingly, the cable management apparatus spreads with extension of the slide assembly, and collapses with retraction. Since the cable management apparatus cantilevers from the slide assembly, sagging due to weight of the cables can occur, negatively affecting the operation of the connected electronic device.

A manipulating portion is formed on a second end of the bolt 4223. Two opposite notches 45 are correspondingly defined in opposite sides of the attachment member 40.
Referring to FIG. 6, the supporting member 50 includes a supporting rail 51 and a blocking piece 53. A coupling post 514 extends upwards from the supporting rail 51 adjacent to a first end of the supporting rail 51. The coupling post 514 includes a neck portion 5141 engaging the supporting rail 51, and a head portion 5143 of a diameter exceeding that of the neck portion 5141, extending therefrom. The supporting rail 51 forms an engaging tongue 512 at a second end of the supporting rail 51. The blocking piece 53 defines a sliding slot 532 running there though. A bulge 534 extends upwards from a bottom wall bounding the sliding slot 532. Two opposite blocking portions 536 extend upwards from a top of the blocking piece 53 adjacent to opposite openings of the sliding slot 532, correspondingly.
Referring to FIGS. 1-8, in assembly, the first mounting bracket 20 pivotally connects to the second end of the first arm segment 12, with a pin 61 pivotally passing through the pivoting portion 121 of the first arm segment 12, and opposite ends of the pin 61 fixed to the corresponding pivot holes 232 of the first mounting bracket 20. The attachment member 40 pivotally connects to the second end of the second arm segment 14, with a pin 62 pivotally passing through the pivoting portion 141 of the second arm segment 14, and the pivoting portion 41 of the attachment member 40. The first mounting bracket 20 and the attachment member 40 are correspondingly coupled to the first rail 710 and the second rail 730 of one of the opposite slide assemblies 700 as follows. The first mounting bracket 20 is received in the first rail 710 from the rear of the first rail 710, until the bolt 2123 of the engaging button 212 is received in the locking hole 711 of the first rail 710. At the same time, the insert 213 of the first mounting bracket 20 extends into the retaining gap 715 of the first rail 710, and the strip 713 of the first rail 710 is received in the cutouts 211. The opposite notches 45 of attachment member 40 correspondingly align with the guiding blocks 735 of the fixing plate 731 of the second rail 730, to enable the attachment member 40 to be received in the guiding slot 736 of the fixing plate 731 of the second rail 730. The attachment member 40 slides rearwards from the second rail 730, until the bolt 4223 is received in the locking hole 733 of the fixing plate 731. Accordingly, the attachment member 40 is secured to the fixing plate 731. The second mounting bracket 30 is received in the first rail 710 of the other slide assembly 700 from the rear of the first rail 710 until the bolt 3123 of the engaging button 312 is received in the locking hole 711 of the first rail 710. At the same time, the insert 313 of the second mounting bracket 30 extends into the retaining gap 715 of the first rail 710, and the strip 713 of the first rail 710 is received in the cutouts 311.
The blocking piece 53 is slidably mounted to the supporting rail 51, with the supporting rail 51 passing through the sliding slot 532 thereof. The bulge 534 abuts the supporting rail 51 to provide a friction force to prevent sliding of the blocking piece 53, unless a driving force is sufficient to overcome the friction force. The engaging tongue 512 is received in the slot 333 of the flange 33 at the bottom of the second mounting bracket 30. The coupling post 514 passes through the coupling hole 234 of the flange 23 at the bottom of the first mounting bracket 20, with the head portion 5143 of the coupling post 514 aligned with the access portion 2341 of the coupling hole 234. The supporting rail 51 is manipulated such that the neck portion 5141 is received in the retaining portion 2343 of the coupling hole 234. Thus, the first end and the second end of the supporting rail 51 are correspondingly connected to the opposite slide assemblies 700. The supporting rail 51 is angled relative to the extension direction of the sliding assemblies 700, with the first end of the supporting rail 51 arranged at the front of the second end of the supporting rail 51.
Referring to FIGS. 7-10, in use, the second end of the second arm segment 14 moves with the second rail 730 relative to the first rail 710, positioning the arm assembly 10 between spreading where the second end of the second arm segment 14 moves away from the second end of the first arm segment 12, and collapsing where the first and second arm segments 12 and 14 are juxtaposition. The supporting rail 51 is disposed under and supporting the arm assembly 10 when both spreading and collapsed. The arm assembly 10 is prevented from sagging. When the arm assembly 10 is folded as shown in FIG. 8, the blocking piece 53 is slid along the sliding rail 51 until one of the blocking portions 536 abuts the arm assembly 10. Therefore, the arm assembly 10 is prevented from swinging rearwards and interfering with rear structures of the equipment rack.
Referring to FIG. 11, when the electronic device is to be maintained from the rear, connecting member 16 is lifted to tilt the arm assembly 10 over the blocking portions 536 of the blocking piece 53. The arm assembly 10 is swung rearwards to provide a space for the maintenance of the electronic device.
Referring to FIGS. 11 and 12, since the two coupling holes 234 are symmetrically defined in the opposite flanges 23 of the first mounting bracket 20, and the two slots 333 are symmetrically defined in opposite flanges 33 of the second mounting bracket 30, by interchanging mounting positions of the first mounting bracket 20 and the second mounting bracket 30, the mounting orientation can be changed conveniently, to enable the arm assembly 10 to swing to open clockwise or counterclockwise, selectively.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments.
