Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cable management device, and more particularly, to a cable management device adapted to slide rails.

2. Description of the Prior Art

Typically, an electronic apparatus configured in a rack system is mounted onto a rack by using a slide rail assembly, such that the electronic apparatus can, through the use of slide rails of the slide rail assembly, be pulled from inside the rack to outside the rack, or be pushed into the rack from outside the rack. Since the electronic apparatus is equipped with cables, the cables need to be supported by using a cable management arm assembly.

As taught in U.S. Pat. No. 7,554,819 B2, a cable management arm assembly is designed to be mounted on a rear end of the slide rail assembly, so that the cable management arm assembly can be expanded with the slide rail. As shown in FIG. 1 of said patent, a frame 1 includes a front arm 11, a rear arm 12, and a support rail 2.

DETAILED DESCRIPTION

As shown in FIG. 1 and FIG. 2, the cable management device 20 according to the first embodiment of the present invention includes a first cable management arm 22, a second cable management arm 24, a first member 26, and a first connecting member 28.

The first cable management arm 22 includes a first end portion 22a and a second end portion 22b away from the first end portion 22a.

The second cable management arm 24 is moveable relative to the first cable management arm 22, and the second cable management arm 24 includes a first end portion 24a and a second end portion 24b away from the first end portion 24a. In practical application, the second cable management arm 24 is pivoted with respect to the first cable management arm 22. For example, the second cable management arm 24 is pivoted and adjacent to the second end portion 22b of the first cable management arm 22. Furthermore, the second end portion 24b of the second cable management arm 24 and the second end portion 22b of the first cable management arm 22 are pivoted with respect to each other. A pivoting base 30 being pivoted to the second end portion 24b of the second cable management arm 24 and the second end portion 22b of the first cable management arm 22 through two shafts 32a and 32b is illustrative of an example hereinafter. Preferably, one of the first cable management arm 22, the second cable management arm 24, and the pivoting base 30 has a cable holding feature 34. The first cable management arm 22, the second cable management arm 24, and the pivoting base 30 all having the cable holding feature 34 is illustrative of an example hereinafter.

The first member 26 is pivoted directly or indirectly with respect to the first cable management arm 22. The cable management device 20 further including a first extension member 36, being pivoted between the first cable management arm 22 and the first member 26, is illustrative of an example hereinafter, and the first member 26 is pivoted and adjacent to the first end portion 22a of the first cable management arm 22 through the first extension member 36.

The first connecting member 28 is connected to the first member 26 in an extendable and retractable manner. As an example, the first member 26 has a first wall 38a, a second wall 38b, and a side wall 40 connected between the first wall 38a and the second wall 38b. The first wall 38a, the second wall 38b, and the side wall 40 define a first channel C1, and the first channel C is configured to accommodate the first connecting member 28. Preferably, the first connecting member 28 has a first feature 42, and the first member 26 includes a corresponding feature 44. The first feature 42 cooperates with the corresponding feature 44 to allow the first connecting member 28 to be displaced within a limited range with respect to the first member 26. As an example, the first feature 42 is a protrusion, and the corresponding feature 44 comprises two stoppers. The protrusion is disposed from one side through to the other side of the side wall 40 of the first member 26, and the protrusion is constrained between the two stoppers.

Preferably, the cable management device 20 further includes a second member 46, a second connecting member 48, and a second extension member 50. The second member 46 is pivoted directly or indirectly with respect to the second cable management arm 24. The second extension member 50 being pivoted between the second cable management arm 24 and the second member 46 is illustrative of an example hereinafter, and the second member 46 is pivoted and adjacent to the first end portion 24a of the second cable management arm 24 through the second extension member 50. Furthermore, the second connecting member 48 is connected to the second member 46 in an extendable and retractable manner. As an example, the second connecting member 48 is accommodated in a second channel C2 defined by the second member 46, and the second connecting member 48 can be displaced within a limited range with respect to the second member 46. For example, the second connecting member 48 has another first feature 49 (such as a protrusion), and the first feature 49 is able to constrain the movement of the second connecting member 48 by cooperating with another corresponding feature 51 (such as two stoppers) on the second member 46. Herein, the structural configuration of the second connecting member 48 and the second member 46 is substantially identical to that of the first connecting member 28 and the first member 26, and related descriptions are omitted herein for simplicity.

Preferably, the cable management device 20 further includes a supporting member 52, a mounting base 54, and a third connecting member 56. The supporting member 52 has a predetermined length, and the supporting member 52 is moveably arranged at a bottom of the first cable management arm 22 and the second cable management arm 24, and the supporting member 52 is configured to support one of the first cable management arm 22 and the second cable management arm 24. The supporting member 52 being connected to the bottom of the pivoting base 30 is illustrative of an example hereinafter. On the other hand, the mounting base 54 is arranged on the supporting member 52. For example, the mounting base 54 is moveably connected (e.g., can be pivoted to) and adjacent to the end portion of the supporting member 52. Since all of the mounting base 54, the first member 26, and the second member 46 are able to pivot, all of the three items can be oriented toward the same direction. The third connecting member 56 can be connected to the mounting base 54 in an extendable and retractable manner. That is, the third connecting member 56 is accommodated in a third channel C3 defined by the mounting base 54, and the third connecting member 56 can be displaced within a limited range with respect to the mounting base 54. Herein, the structural configuration of the third connecting member 56 and the mounting base 54 is substantially identical to that of the first connecting member 28 and the first member 26 (or substantially identical to that of the second connecting member 48 and the second member 46), and related descriptions are omitted herein for simplicity.

As shown in FIG. 2, the first connecting member 28 can be located at a first position P11 relative to the first member 26, the second connecting member 48 can be located at a first position P21 relative to the second member 46, and the third connecting member 56 can be located at a first position P31 relative to the mounting base 54.

As shown in FIG. 3, the first connecting member 28 is able to be displaced to a second position P12 from the aforementioned first position P11 relative to the first member 26, the second connecting member 48 is able to be displaced to a second position P22 from the aforementioned first position P21 relative to the second member 46, and the third connecting member 56 is able to be displaced to a second position P32 from the aforementioned first position P31 relative to the mounting base 54.

As shown in FIG. 4, a rack system includes the cable management device 20, a first slide rail assembly 58 (i.e., a slide rail assembly), and a second slide rail assembly 60 (i.e., another slide rail assembly). Herein, the cable management device 20 and the slide rail assembly 58 compose a coupling assembly.

The first slide rail assembly 58 includes a first rail 62 and a second rail 64. The second rail 64 is fixed to a first rack post 65a and a second rack post 65b of a rack 65, and the first rail 62 is displaceable relative to the second rail 64. Preferably, the first slide rail assembly 58 further includes a middle rail 66 moveably mounted between the first rail 62 and the second 64 and configured to increase movement of the first rail 62 relative to the second rail 64. Similarly, the second slide rail assembly 60 includes a third rail 68 and a fourth rail 70. The fourth rail 70 is fixed to another first rack post 65a and another second rack post 65b of the rack 65, and the third rail 68 is displaceable relative to the fourth rail 70.

The first cable management arm 22 of the cable management device 20 is connected to the first rail 62 (as an example, connected to a rear end of the first rail 62) of the first slide rail assembly 58 through the first connecting member 28. The second cable management arm 24 is connected to the second rail 64 of the first slide rail assembly 58. Herein, the second cable management arm 24 is connected to the second rail 64 (as an example, connected to a rear end of the second rail 64) of the first slide rail assembly 58 through the second connecting member 48. Furthermore, the third connecting member 56 on the supporting member 52 is configured to be connected to the fourth rail 70 (as an example, connected to a rear end of the fourth rail 70) of the second slide rail assembly 60.

Herein, an electronic device 72 is mounted between the first slide rail assembly 58 and the second slide rail assembly 60, and the electronic device 72 can be pulled from inside to outside the rack 65 toward a first direction D1 through the first rail 62 and the third rail 68. Corresponding to the first rail 62 of the first slide rail assembly 58 (or the electronic device 72), the first cable management arm 22 displaces outside the rack 65 toward the first direction D1, so as to expand relative to the second cable management arm 24. The cable holding feature 34 is configured to accommodate the cables behind the electronic device 72, and the cable management feature 34 mentioned herein is obvious to those of ordinary skill in the art, and related descriptions are omitted herein for simplicity. Furthermore, the supporting member 52 is configured to support the first cable management arm 22 or the second cable management arm 24.

As shown in FIG. 5, the electronic device 72 is able to be pushed from outside to inside the aforementioned rack 65 along a second direction D2. Herein, the first cable management arm 22 is retracted relative to the second cable management arm 24 in response to a displacement of the first rail 62 of the first slide rail assembly (or the electronic device 72) along the second direction D2. Furthermore, the supporting member 52 is configured to support the first cable management arm 22 or the second cable management arm 24.

In addition, the first cable management arm 22 is in a retracted state relative to the second cable management arm 24. When the first connecting member 28 is located at the first position P11 relative to the first member 26, the second connecting member 48 is located at the first position P21 relative to the second member 46, and/or the third connecting member 56 is located at the first position P31 relative to the mounting base 54, a first spacing S1 is defined between a rear side of the electronic device 72 and (the first cable management arm 22 of) the cable management device 20. It should be noticed that the first spacing S1 is occasionally too narrow for the cables behind the electronic device 72 to be stored in the first spacing S1, or the first spacing S1 is occasionally too narrow for operators to execute cable arrangement behind the electronic device 72.

As shown in FIG. 6, the first cable management arm 22 is in the retracted state relative to the second cable management arm 24. With the first connecting member 28 being located at the second position P12 relative to the first member 26, the second connecting member 48 being located at the second position P22 relative to the second member 46, and/or the third connecting member 56 being located at the second position P32 relative to the mounting base 54 is able to increase the connection length of the cable management device 20. In other words, the connection length between the cable management device 20 and the slide rail assemblies 58 and 60 can be increased. Accordingly, a second spacing S2 is defined between the rear side of the electronic device 72 and (the first cable management arm 22 of) the cable management device 20, with the second spacing S2 being greater than the aforementioned first spacing S1. Therefore, the second spacing S2 facilitates the operators to utilizes space behind the electronic device 72, e.g., it facilitates the operators to execute the cable arrangement.

As shown in FIG. 7 and FIG. 8, the cable management device 200 according to the second embodiment of the present invention can be implemented in the first slide rail assembly 58 and the second slide rail assembly 60. Different from the cable management device 20 of the first embodiment, using the first connecting member 28, the second connecting member 48 or the third connecting member 56 for displacement in the extension or retraction manner to adjust spacing, the cable management device 200 of the second embodiment improves spacing issue by using detachable mounting members.

In practical application, the cable management device 200 includes a first cable management arm 202, a second cable management arm 204, a first member 206, and a first mounting member 208.

The second cable management arm 204 is movable relative to the first cable management arm 202. Herein, the second cable management arm 204 is pivoted with respect to the first cable management arm 202, e.g., the ends of the second cable management arm 204 and the first cable management arm 202 are pivot with respect to each other, and the second cable management arm 204 is connected to the second rail 64 of the first slide rail assembly 58.

The first member 206 is directly or indirectly pivoted with respect to the first cable management arm 202. The first mounting member 208 is detachable relative to the first member 206. In the present embodiment, the cable management device 200 further includes a first connecting member 210 connected to the first member 206, and the first mounting member 208 is detachably connected to the first connecting member 210. In an alternative embodiment where the first connecting member 210 is omitted, the first mounting member 208 can also be directly and detachably connected to the first member 206, and the present invention is not limited thereto. Furthermore, the first mounting member 208 is detachably connected between the first member 206 and (the rear end of) the first rail 62. The first mounting member 208 has a first predetermined length, and the first mounting member 208 is used to increase a connection length defined between the first member 206 and the first rail 62. Herein, the configuration of the first mounting member 208 is oriented substantially along a longitudinal direction of the first rail 62 of the first slide rail assembly 58. Furthermore, a first connecting portion 209a and a second connecting portion 209b are disposed on two opposite ends of the first mounting member 208, wherein the first connecting portion 209a has a latching mechanism 211a, and the second connection portion 209b has at least one inserting feature 211b. According to such arrangement, corresponding features can be disposed on the slide rail and the cable management device to engage with the first mounting member 208. As an example, the latching mechanism 211a of the first connecting portion 209a can be detachably connected to the inserting feature 211b of the second connecting portion 209b. Accordingly, the aforementioned slide rail and the cable management device allow the first mounting member 208 to be detachably connected between the first member 206 and the first rail 62 in a latching or inserting manner, but the present invention is not limited thereto.

Preferably, the cable management device 200 further includes a second member 212, a second connecting member 214 and a second mounting member 216.

In the present embodiment, the second connecting member 214 is connected to the second member 212, and the second mounting member 216 is detachably connected to the second connecting member 214. In an alternative embodiment where the second connecting member 214 is omitted, the second mounting member 216 can also be directly and detachably connected to the second member 212, and the present invention is not limited thereto. Furthermore, the second mounting member 216 has a similar configuration as the aforementioned first mounting member 208 does, wherein the second mounting member 216 has a first connecting portion 217a, a second connecting portion 217b, a latching mechanism 219a, and an inserting feature 219b. Accordingly, the second mounting member 216 can be detachably connected between the second connecting member 214 and (the rear end of) the second rail 64. The second mounting member 216 has a second predetermined length, and the second mounting member 216 is used to increase a connection length defined between the second member 212 and the second rail 64. Herein, the configuration of the second mounting member 216 is substantially oriented along a longitudinal direction of the second rail 64 of the first slide rail assembly 58. Furthermore, the second mounting member 216 can be detachably connected between the second member 212 and the second rail 64 in a latching or inserting manner, but the present invention is not limited thereto.

Preferably, the cable management device 200 further includes a supporting member 218, and the supporting member 218 is used to support one of the first cable management arm 202 and the second cable management arm 204.

Accordingly, the third mounting member 222 can be detachably connected between the mounting base 220 and (the rear end of) the fourth rail 70 of the second slide rail assembly 60. The third mounting member 222 has a third predetermined length, and the third mounting member 222 is used to increase a connection length defined between the mounting member 220 and the fourth rail 70. Herein, the configuration of the third mounting member 222 is substantially oriented along a longitudinal direction of the fourth rail 70 of the second slide rail assembly 60. Furthermore, the third mounting member 222 can be detachably connected between the mounting base 220 and the fourth rail 70 in a latching or inserting manner, but the present invention is not limited thereto.

When spacing (such as the aforementioned first spacing S1) between the electronic device 72 and the cable management device 200 being adjusted to a larger third spacing S3 is desired, it is able to adjust the spacing between the cable management device 72 and the electronic device 72 by the first mounting member 208 with the first predetermined length being detachably connected between the first member 206 and the first rail 62, and/or the second mounting member 216 with the second predetermined length being detachably connected between the second member 212 and the second rail 64, and/or the third mounting member 222 with the third predetermined length being detachably connected between the mounting base 220 and the fourth rail 70.
