Description

Slide rail assembly and wire arranging device thereof

Technical Field

The present invention relates to a cable management device, and more particularly, to a cable management device applicable to a slide rail or a rack system.

Background

Generally, in rack-mounted systems, a load-bearing object is mounted to a rack, usually by means of a pair of slide assemblies. The carrier is, for example, a server or a power supply. Wherein the carrier has wires or cables (cables). Therefore, in order to properly place the wires of the carrier, a wire management assembly (or wire management arm) has been developed.

For example, U.S. patent publication No. US 7,554,819B2 discloses a wire management arm assembly that can be applied to a pair of slide rail assemblies. As can be seen from fig. 1 and 2 of the present application, each slide rail assembly includes an outer rail a, a middle rail B and an inner rail C. The wire management arm assembly comprises a front arm 11 and a rear arm 12 which are connected to a support rail 2 by means of a pivot 13 and are movable on the support rail 2. Wherein, a plurality of wire arranging retainers 15 are arranged on the front arm 11 and the rear arm 12. Further, as can be seen from fig. 15 of the same case, the rear arm 12 of the wire organizing arm assembly is connected to the outer rail a of one of the slide rail assemblies by means of a connector 5, and the front arm 11 of the wire organizing arm assembly is connected to the inner rail C of the slide rail assembly by means of an insert 7; on the other hand, one end of the support rail 2 can be connected to the middle rail B of one of the slide rail assemblies by a first sliding member 3.

For example, U.S. patent publication No. US 7,472,795B2 discloses a management assembly, as shown in fig. 1 of the drawings, in which a device 36 is mounted to a frame 31 by way of rail assemblies 24, 26. Wherein each slide assembly includes a fixed portion 32 and a movable portion 34. The device 36 is mounted to the movable portion 34. The management assembly includes a first arm 50, a second arm 60 and a cross member 42. The first arm 50 and the second arm 60 each have an

outer end

52,62 that is movably engaged with the cross member 42 via a slider 48, and the first arm 50 and the second arm 60 each have an

inner end

54,64 that is coupled to a first arm support 56 and a second arm support 66, respectively. The first arm 56 is connected to the movable portion 34 of one of the slide assemblies, and the second arm 66 is connected to the fixed portion 32 of one of the slide assemblies. On the other hand, the two ends of the cross member 42 are respectively movable on the fixing portion 32 of the

slide rail assemblies

24,26 by a first frame 38 and a second frame 40. As can be seen from fig. 3, 4 and 5 of the present disclosure, the first arm 50 and the second arm 60 can be relatively movably unfolded and can move on the cross member 42 via the sliding block 48 based on the movement of the movable portion 34 and the device 36 from a retracted position to an extended position.

For example, U.S. patent publication No. US 8,387,933B2 discloses a wire management device including an arm assembly 10, a first mounting member 20, a second mounting member 30 and a support member 50. The arm assembly 10 includes a rear arm 11 and a front arm 12 connected to the rear arm 11 by a connecting member 14. The forearm 12 includes a first arm segment 121 and a second arm segment 122 connected to the first arm segment 121. A connecting piece 22 of the first mounting member 20 is pivotally connected to one end of the rear arm 11, and the first mounting member 20 is mounted to a fixed rail 410; on the other hand, the second mounting member 30 is pivotally connected to an end of the second arm section 122, and the second mounting member 30 is mounted to an inner rail 430. The supporting member 50 is located at the rear end of the two middle rails 420 of the slide rail assembly 400.

Therefore, although the above-mentioned related patents all provide the wire arranging assembly for placing the wire, the wire arranging assembly of these related patents includes two wire arranging arms pivoted relatively, and the two wire arranging arms can be unfolded relatively with the movable rail of the slide rail assembly moving relative to the fixed rail. However, depending on the market demand, the extension length (or opening length) of the slide rail assembly may need to be increased, that is, the movable travel of the movable rail of the slide rail assembly relative to the fixed rail needs to be longer, so that the wire management assembly having the two-or three-section wire management arm may not be suitable in the case of limited deployment length.

Detailed Description

Fig. 1 shows a rack system including a carrier 20 mountable to a rack 24 by a first slide assembly 22 and a second slide assembly 23. The carrier 20 may be an electronic device, such as a server and/or a power supply. The frame 24 includes a pair of first posts 26a and a pair of second posts 26 b. Each slide assembly includes a first rail 28. Two portions of the first rail 28 may be configured with a first bracket 30 (e.g., a front bracket) and a second bracket 32 (e.g., a rear bracket) for mounting to the first post 26a and the second post 26b, respectively, of the frame 24.

As shown in fig. 2, each slide rail assembly further includes a second rail 34 and a third rail 36. The second rail 34 is used for mounting the bearing object 20; the third rail 36 is movably installed between the first rail 28 and the second rail 34 for extending the moving stroke of the second rail 34 relative to the first rail 28. Further, the first slide rail assembly 22 includes a wire management device 37 located at the rear of the carrier 20. Specifically, the wire management device 37 includes a first wire management arm and a second wire management arm. Wherein the first set of wire management arms comprises two arms, such as a first arm 38a and a second arm 38 b; the second set of wire management arms includes two arms, such as a third arm 38c and a fourth arm 38 d. Preferably, the wire management device 37 further comprises an arm, such as a fifth arm 38 e. Each arm (38a,38b,38c,38d,38e) has at least one wire organizing feature 35, the wire organizing features 35 can be a slot or a seat, and the wire organizing features 35 are used for organizing the wires of the carrier 20, which is not described herein for brevity since this part is a technical category that can be understood by those skilled in the art.

As shown in fig. 3, the first arm 38a and the second arm 38b of the first set of wire management arms are movable relative to each other; the third arm 38c and the fourth arm 38d of the second set of wire management arms are movable relative to each other; the fifth arm 38e is movable relative to the second wire management arm. Wherein the third arm 38c of the second set of wire management arms is connected to the second arm 38b of the first set of wire management arms.

In this embodiment, the arms (38a,38b,38c,38d,38E) each include two portions, such as a first end E1 and a second end E2, which are opposite to each other, and the arms (38a,38b,38c,38d,38E) are sequentially pivotally connected to each other by a first pivot 40, a second pivot 42, a third pivot 44 and a fourth pivot 46.

Specifically, the first ends E1 of the first and

second arms

38a and 38b of the first wire arranging arm can be pivotally connected to each other by the first pivot 40. For example, a first auxiliary seat 48 is disposed between the first arm 38a and the second arm 38b for pivotally connecting the two first pivoting members 40; the second end E2 of the second arm 38b of the first wire organizing arm and the second end E2 of the third arm 38c of the second wire organizing arm can be pivotally connected to each other by the second pivot 42. For example, a second auxiliary seat 50 is disposed between the second arm 38b and the third arm 38c for pivotally connecting the two second pivotal members 42; the first end E1 of the third arm 38c of the second wire organizing arm and the first end E1 of the fourth arm 38d of the second wire organizing arm may be pivotally connected to each other by the third pivot 44. For example, a third auxiliary seat 52 is disposed between the third arm 38c and the fourth arm 38d for pivotally connecting the two third pivotal members 44; the second end E2 of the fourth arm 38d of the second wire organizing arm and the second end E2 of the fifth arm 38E can be pivotally connected to each other by the fourth pivot 46. For example, a fourth auxiliary seat 54 is disposed between the fourth arm 38d and the fifth arm 38e for pivotally connecting the two fourth pivots 46. Accordingly, the arms (38a,38b,38c,38d,38e) are movable relative to each other. It should be noted that, in this embodiment, although the arms (38a,38b,38c,38d,38e) are pivoted relative to each other by the additional auxiliary seats (48,50,52,54), in practice, the arms (38a,38b,38c,38d,38e) may also be pivoted relative to each other directly by the pivoting member, which is not limited in implementation.

As shown in fig. 4, the second end E2 of the first arm 38a of the first wire organizing arm can be connected to the first rail 28 of the first slide rail assembly 22. For example, a first fitting 56 may be disposed adjacent the rear end of the first rail 28 of the first rail assembly 22, and the second end E2 of the first arm 38a may be connected to the first fitting 56 by a fifth pivot 58. On the other hand, the first end E1 of the fifth arm 38E can be connected to the carrier 20. For example, a second fitting member 60 can be disposed adjacent to the rear portion of the carrier 20, and the first end E1 of the fifth arm 38E can be connected to the second fitting member 60 by a sixth pivot member 62.

Preferably, the wire management device 37 further includes a support 64 for supporting between the arms (38a,38b,38c,38 d). The support member 64 is mounted to the third rail 36 of one of the pair of slide assemblies. For example, one end of the support member 64 may be mounted to the third rail 36. Preferably, the support member 64 has a mounting member 66 at each end (this portion may be matched to fig. 6), and the mounting member 66 can be detachably fastened to a support portion 69 adjacent the rear end of the third rail 36 by a mounting feature 68, such as a hook or a nail. It should be noted that although the supporting member 64 is installed on the third rail 36 in the embodiment, in practice, the supporting member 64 may be connected to the third rail 36 by a screw manner, and the implementation is not limited.

As shown in fig. 5 and 6, one of the two arms of the second wire management arm, for example, the third arm 38c, is pivotally connected between two ends of the supporting member 64. For example, the cable management device further includes a connecting member 70, the connecting member 70 can be mounted between two ends of the supporting member 64 by two fasteners 72, and a portion between the first end E1 and the second end E2 of the third arm 38c can be pivotally connected to the connecting member 70 by a shaft 74.

As shown in fig. 7 and 8, each of the slide assemblies, such as the first rail 28 of the first slide assembly 22, includes a detent release feature 76, which may be an additional part that is riveted, welded, or bolted to the first rail 28; alternatively, the detent release feature 76 may be formed directly on the first rail 28 by machining, such that the detent release feature 76 has a particular shape or configuration. Here, the tripping feature 76 has a guide section 78, such as a ramp or a curved surface. As shown in fig. 9, the first slide assembly 22 further includes a locking member 80 mounted on the third rail 36, and the locking member 80 has a locking portion 82; on the other hand, the second rail 34 has an aperture 84 and a stop 86 adjacent the aperture 84. The locking portion 82 of the locking member 80 can be used to lock the blocking portion 86.

As shown in fig. 10, each of the slide assemblies, such as the first slide assembly 22, is in a state, such as a retracted state. In the retracted state, the second rail 34 and the third rail 36 of the first slide assembly 22 are located at a first position P1 relative to the first rail 28. The locking member 80 further includes a contact portion 88, and a portion between the contact portion 88 and the locking portion 82 is pivotally connected to the third rail 36. Preferably, an elastic force is provided to the locking member 80 by an elastic member 90, and the elastic member 90 has an elastic portion 92 acting on the contact portion 88 to keep the contact portion 88 facing the first rail 28, and the locking portion 82 can extend into the hole 84 to keep locking the blocking portion 86 of the second rail 34.

As shown in fig. 11 and 12, when the second rail 34 and the third rail 36 are moved relative to the first rail 28 from the first position P1 to a first direction D1, such as an extending direction, the locking portion 82 of the locking member 80 locks the blocking portion 86 of the second rail 34, so that the second rail 34 and the third rail 36 can move synchronously in the first direction D1 until the second rail 34 and the third rail 36 move in the first direction D1 to approach a predetermined position L, the contact portion 88 of the locking member 80 contacts the guiding segment 78 of the releasing feature 76 of the first rail 28, so that the locking member 80 is deflected by an angle to release the locking portion 82 of the locking member 80 from locking the blocking portion 86 of the second rail 34. That is, when the third rail 36 moves to the predetermined position L in the first direction D1 relative to the first rail 28, the releasing feature 76 can release the locking of the locking member 80 to the blocking portion 86 of the second rail 34, so that the locking portion 82 of the locking member 80 is disengaged from the blocking portion 86. In this state, the third rail 36 is no longer synchronously movable with the second rail 34, i.e., the second rail 34 can further move in the first direction D1 relative to the third rail 36.

As shown in fig. 13, each of the

rail assemblies

22,23 is in the retracted state. The second end E2 of the first arm 38a of the wire management device 37 is pivotally connected to the first fitting 56 of the first rail 28 of the first rail assembly 22, and the first end E1 of the fifth arm 38E of the wire management device 37 is pivotally connected to the second fitting 60 of the carrier 20. In addition, the supporting member 64 is used for supporting the wire arranging device 37. Further, when each of the

slide assemblies

22,23 is in the retracted state, most of the supporting object 20 is located in the frame 24. On the other hand, the wire management device 37 is in a first state, for example, the arms (38a,38b,38c,38d,38e) of the wire management device 37 are in a state of being close to each other.

As shown in fig. 13 and 14, when the carrier 20 is pulled out from the frame 24, the second rail 34 and the third rail 36 move from the first position P1 to the first direction D1, for example, an extending direction, relative to the first rail 28, and the carrier 20 is also displaced to the outside of the frame 24 along with the first direction D1. The second track 34 and the third track 36 can move synchronously in the first direction D1, and the third track 36 does not move synchronously with the second track 34 until the predetermined position L is reached (for the principle of synchronization and release of the synchronization relationship between the second track 34 and the third track 36, please refer to fig. 10, fig. 11, and fig. 12 and their related descriptions, which is not described herein for brevity).

Specifically, during the movement of the second rail 34 and the third rail 36 in the first direction D1, the supporting member 64 is displaced in response to the movement of the third rail 36 relative to the first rail 28. On the other hand, the wire management device 37 can gradually take a second state from the first state, for example, the unfolded state, in response to the second rail 34 moving from the first position P1 to the first direction D1 relative to the first rail 28. Further, the fifth arm 38e can be moved in response to the second rail 34 (or the carrier 20) moving from the first position P1 to the first direction D1 relative to the first rail 28. Since the third rail 36 can move synchronously with the second rail 34, the first arm 38a and the second arm 38b of the first wire management arm are first unfolded until the synchronous movement relationship between the second rail 34 and the third rail 36 is released when the second rail 34 and the third rail 36 reach the predetermined position L.

As shown in fig. 15, when the synchronous moving relationship is released, the second rail 34 (or the carrying object 20) can move continuously in the first direction D1 with respect to the third rail 36 to further drive the fifth arm 38e of the wire management device 37, wherein one of the two arms of the second wire management arm, for example, the third arm 38c, is pivoted between the two ends of the supporting member 64, so that the third arm 38c and the fourth arm 38D of the second wire management arm are sequentially unfolded in response to the movement of the fifth arm 38e, and then drive the first arm 38a and the second arm 38b of the first wire management arm. The cable management device 37 is driven to the second state until the second rail 34 reaches a second position P2 relative to the first rail 28, such that the slide assembly is in a fully extended state.

It should be noted that when the second rail 34 moves from the second position P2 to the retracted position P1 in a second direction, such as a retracting direction (opposite to the first direction D1), relative to the first rail 28, the wire management device 37 also returns to the first state from the second state (please refer to fig. 13, which is not described herein for brevity).

FIG. 16 shows a second embodiment of the present invention. The second embodiment is substantially different from the first embodiment in that: the second end E2 of the first arm 200a of the first set of wire organizing arms is connected to the second post 202 of the rack. For example, the second end E2 of the first arm 200a is connected, e.g., pivotally connected, to a third fitting 204 of the second post 202.

FIG. 17 shows a third embodiment of the present invention. Unlike the first end E1 of the fifth arm 38E of the first embodiment connected to the carrier 20, the first end E1 of the fifth arm 300E of the wire management device of the third embodiment can be connected to the second rail 302 of the slide rail assembly 301. For example, the first end E1 of the fifth arm 300E can be connected, e.g., pivotally connected, to a fourth fitting 304 of the second rail 302, which can also allow the wire management device to be brought from a first state to a second state in response to the second rail 302 moving relative to the first rail 306.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are: compared with the prior art, since the wire management device 37 of the present embodiment includes more than two (e.g. more than four) wire management arms (38a,38b,38c,38d,38e), the wire management device 37 of the present embodiment can correspond to the total extension length (or opening length) of a longer slide rail assembly, and since the second rail 34 and the third rail 36 have a synchronous moving relationship within a predetermined stroke, and one of the two

arms

38c,38d of the second wire management arm is relatively pivoted between the two ends of the supporting member 64, the wire management device 37 can be gradually or sequentially unfolded or folded, so that the multi-section wire management device 37 has a stable unfolding or folding effect.

Although the present invention has been described with reference to the present specific embodiments, it will be recognized by those skilled in the art that the above embodiments are illustrative only, and various equivalent changes and modifications may be made without departing from the spirit of the present invention, and therefore, it is intended to cover in the appended claims all such changes and modifications as fall within the true spirit of the invention.
