Detailed Description

As shown in fig. 1, 2 and 3, the embodiment of the present invention includes a slide rail assembly 22, a wire arranging device 24, and a first connecting device 26, and preferably, a second connecting device 28.

The slide assembly 22 includes a first rail 30, a second rail 32 and the first rail 30 capable of moving relatively, and preferably, further includes a third rail 34 movably installed between the first rail 30 and the second rail 32, the third rail 34 being used to extend the distance of the second rail 32 and the first rail 30 moving relatively to each other. The first rail 30 has a front portion 30a and a rear portion 30b, and the second rail 32 has a front portion 32a and a rear portion 32 b.

The wire management device 24 includes a first wire management arm 36 and a second wire management arm 38. The second wire management arm 38 is movably connected, e.g., pivotally connected, to the first wire management arm 36. Specifically, the first wire management arm 36 and the second wire management arm 38 both have a first end E1 and a second end E2 located opposite to the first end E1. The first ends E1 of the first wire-arranging arm 36 and the second wire-arranging arm 38 are pivotally connected to each other. Herein, the first ends E1 of the first wire arranging arm 36 and the second wire arranging arm 38 are pivotally connected to each other via a base 40. For example, the first end E1 of the first wire arranging arm 36 and the first end E1 of the second wire arranging arm 38 are pivotally connected to two sides of the base 40 by a first shaft 42a and a second shaft 42b, respectively. The first wire management arm 36, the second wire management arm 38 and the base 40 are all configured with wire management features 44, and the wire management features 44 are used for supporting a cable of an electronic device, which is not described herein for brevity since this part is within the technical scope that can be understood by those skilled in the art.

The first connecting means 26 is used to detachably connect the first wire management arm 36 to the first rail 30. The second connecting means 28 is used to detachably connect the second wire management arm 38 to the second rail 32. In this embodiment, the second connecting means 28 has a substantially identical structural configuration to the first connecting means 26. For example, the first connecting device 26 and the second connecting device 28 each include two fittings and a resilient member. Wherein a first fitting 47 of the second connecting device 28 is pivotally connected to the second end E2 adjacent to the second wire arranging arm 38, a second fitting 49 of the second connecting device 28 is connected to the rear portion 32b adjacent to the second rail 32, and an elastic member 51 of the second connecting device 28 can prevent the first fitting 47 and the second fitting 49 of the second connecting device 28 from being detached from each other. Since the principle of the first wire-arranging arm 36 being detachably connected to the first rail 30 is substantially the same as the principle of the second wire-arranging arm 38 being detachably connected to the second rail 32, for the sake of simplicity, in the following embodiments, only how the first wire-arranging arm 36 is detachably connected to the first rail 30 through the first connecting device 26 will be described.

Specifically, the first connecting device 26 includes a first fitting 46, a second fitting 48 and an elastic member 50. The first fitting 46 and the second fitting 48 are respectively arranged on the first wire arranging arm 36 and the first rail 30, and the first fitting 46 and the second fitting 48 can be in a mutually mounted state (as shown in fig. 1 or fig. 4) by matching a receiving structure 52 and a protrusion 54. Preferably, the receiving structure 52 is a hole or slot. The receiving structure 52 includes a first portion 52a (or lower portion) and a second portion 52b (or upper portion) in communication with the first portion 52a, the second portion 52b being smaller in size than the first portion 52 a. After the first portion 52a of the receiving structure 52 is sleeved on the protrusion 54 and relatively displaced, the receiving structure 52 can be mounted on the protrusion 54 for positioning. Preferably, the projection 54 includes a head 54a and a body 54b connected to the head 54a, the body 54b being smaller in size than the head 54 a. When the receiving structure 52 is mounted on the protrusion 54 and positioned, the head 54a of the protrusion 54 is blocked on one side of the second portion 52b of the receiving structure 52 (as shown in fig. 1 or fig. 4).

Here, the first fitting 46 has the receiving structure 52, and the second fitting 48 is provided with the protrusion 54, for example, although the number of the receiving structures 52 and the protrusions 54 is two in the embodiment, the implementation is not limited. Further, the first fitting 46 is pivotally connected to the second end E2 adjacent to the first wire arranging arm 36 through a pivot 56a, and the second fitting 48 is connected to the rear portion 30b adjacent to the first rail 30. The second fitting 48 can be detachably connected to the first rail 30 by screwing or clipping, or the second fitting 48 can be fixedly connected to the first rail 30 by riveting or welding, in other words, the second fitting 48 can be regarded as a part of the first rail 30 after being connected to the first rail 30.

The elastic element 50 of the first connecting device 26 is attached to one of the first fitting 46 and the second fitting 48, and the elastic element 50 is, for example, an elastic sheet, but any element with elastic force or flexible force can be used. The elastic member 50 includes an elastic portion 50a and a stopper 50b disposed on the elastic portion 50a of the elastic member 50. Preferably, the stopping portion 50b extends from the elastic portion 50a, and preferably, the stopping portion 50b of the elastic member 50 protrudes relative to the elastic portion 50 a.

When the first fitting 46 is displaced from a first position P1 (fig. 6) to a second position P2 (fig. 4) along a first direction D1 relative to the second fitting 48, the first fitting 46 is prevented from being disengaged from the second fitting 48 by the stop 50b being located at one of the first fitting 46 and the second fitting 48 (fig. 1 or 4).

As shown in fig. 4, the first fitting 46 and the second fitting 48 include a first side wall (or upper side wall), a second side wall (or lower side wall), and a middle wall connected between the first side wall and the second side wall in corresponding positions.

Specifically, the first fitting 46 includes a first side wall 46a (or upper side wall), a second side wall 46b (or lower side wall), and a middle wall 46c connected between the first side wall 46a and the second side wall 46 b. On the other hand, the second fitting 48 includes a first side wall 48a (or upper side wall), a second side wall 48b (or lower side wall), and a middle wall 48c connected between the first side wall 48a and the second side wall 48 b.

In this embodiment, the receiving structure 52 is located on the middle wall 46c of the first fitting 46; the projection 54 is disposed on the middle wall 48c of the second fitting 48; and the elastic member 50 is attached to the second fitting 48, for example, one end of the elastic portion 50a of the elastic member 50 is connected to the back side (for example, the side away from the first fitting 46) of the middle wall 48c of the second fitting 48.

When the first fitting 46 and the second fitting 48 are in the assembled state, the stop portion 50b is located above the first sidewall 46a of the first fitting 46, and the stop portion 50b is in a locking position K1 for preventing the first fitting 46 from being separated from the second fitting 48 along a second direction D2 opposite to the first direction D1.

As shown in fig. 5, 6 and 7, when the first fitting 46 is to be detached from the second fitting 48, the user applies a force F to the elastic member 50 to make the blocking portion 50b swing relative to the elastic portion 50a to generate an elastic force to be separated from the upper side of the first side wall 46a of the first fitting 46 (as shown in fig. 5), and then the blocking portion 50b is switched from the locking position K1 to an unlocking position K2, in which the first wire management arm 36 moves relative to the first rail 30 in the second direction D2, so that the head 54a of the protrusion 54 can be moved back from the second portion 52b of the accommodating structure 52 to the first portion 52a (as shown in fig. 6), so that the first wire management arm 36 and the first rail 30 can be separated from each other (as shown in fig. 7). In detail, the blocking portion 50b can be located between a locking position K1 and an unlocking position K2 in response to the elastic force of the elastic member 50. When the first portion 52a of the receiving structure 52 of the first fitting 46 is fitted over the protrusion 54 of the second fitting 48, the elastic element 50 can be shifted to generate an elastic force manually or in response to the first fitting 46 being fitted over the second fitting 48, so that the blocking portion 50b is in the unlocking position K2, and the first fitting 46 can be disengaged from the second fitting 48. When the first fitting 46 is displaced from a first position P1 to a second position P2 along a first direction D1 relative to the second fitting 48, the second portion 52b of the receiving structure 52 of the first fitting 46 is located opposite to the protrusion 54 of the second fitting 48, and the blocking portion 50b is restored from the unlocking position K2 to the locking position K1 by releasing the elastic force of the elastic member 50, wherein the blocking portion 50b is used to prevent the first fitting 46 from being disengaged from the second fitting 48 along a second direction D2 opposite to the first direction D1.

It should be noted that, referring to fig. 7, fig. 6 and fig. 4 in sequence, when the first wire arranging arm 36 and the first rail 30 are to be installed with each other again, for example, the first wire arranging arm 36 and the first rail 30 can be close to each other, at this time, the elastic member 50 can be slightly pushed or operated by the external force F to accumulate an elastic force (as shown in fig. 6); further, when the first fitting 46 is mounted to the second fitting 48 in response to the wire management device 24 (or the first wire management arm 36) in the first direction D1 (e.g., downward direction), the body 54b of the protrusion 54 enters from the first portion 52a of the receiving structure 52 and is mounted to the second portion 52b (as shown in fig. 4), wherein the elastic force is released by the elastic member 50 such that the stop portion 50b can provide a blocking effect for the first sidewall 46a of the first fitting 46 to prevent the first fitting 46 from being detached from the second fitting 48 in the second direction D2 (e.g., upward direction) opposite to the first direction D1 (as shown in fig. 4). It should be noted that the first direction D1 and the second direction D2 are only schematic directions, and the first direction D1 and the second direction D2 may be opposite directions in implementation, and are not limited in implementation. It should be noted that the second portion 52b of the receiving structure 52 is sized larger than the body portion 54b of the projection 54, but smaller than the head portion 54a of the projection 54. Therefore, when the first fitting 46 and the second fitting 48 are in the installation position shown in fig. 4, they cannot be arbitrarily displaced from each other in the horizontal direction (H1) and the vertical direction (V1), and thus have a stable positioning effect. In addition, a part of the elastic portion 50a of the elastic member 50 has an opening 50c (see fig. 2), which helps the elastic member 50 to be easily pushed or operated by an external force F to accumulate the elastic force (as shown in fig. 5 and 6), i.e. a user can operate the elastic member 50 more easily and easily with less effort, so that the blocking portion 50b is deflected at an angle relative to the elastic portion 50a to help the installation of the first fitting 46 and the second fitting 48.

As shown in fig. 8, in a rack system, an electronic device 58 can be located in a rack 60 by folding the second rail 32 of the pair of slide assemblies 22 relative to the first rail 30, wherein the first wire management arm 36 and the second wire management arm 38 are close to each other. Specifically, the electronic device 58 may be mounted to the rack 60 by a pair of slide assemblies 22, and the first rail 30 of each slide assembly 22 is mounted to a first post 60a and a second post 60b of the rack 60 by a first bracket 62 and a second bracket 64. The second rail 32 can carry the electronic device 58, the electronic device 58 generally has a cable 66, and the first wire arranging arm 36, the second wire arranging arm 38 or the wire arranging feature 44 of the base 40 of the wire arranging device 24 can support the cable 66. Since this part is within the technical scope that can be understood by a person skilled in the art, it is not described herein for the sake of brevity. The wire arranging device 24 is detachably connected to one of the pair of slide rail assemblies 22 (as shown in fig. 8, the wire arranging device 24 is detachably connected to the slide rail assembly 22 on the right side of the rack 60). Specifically, the first connecting device 26 can detachably connect the first wire management arm 36 to the first rail 30, and the second connecting device 28 can detachably connect the second wire management arm 38 to the second rail 32.

As shown in fig. 9, the electronic device 58 can be pulled out of the rack 60 from the inside of the rack 60 by the displacement of the second rail 32 of the pair of slide assemblies 22 relative to the first rail 30. Wherein the first wire management arm 36 and the second wire management arm 38 pivot relative to each other for deployment.

As shown in fig. 10, the first connecting device 26 and the second connecting device 28 can provide a mechanism for detachably connecting the slide rail and the wire management arm to each other, and in another embodiment, the wire management device 24 is detachably connected to the slide rail assembly 22 on the left side of the frame 60. For example, the first connecting device 26 can detachably connect the first wire handling arm 36 to the first rail 30 of the left slide assembly 22, and the second connecting device 28 can detachably connect the second wire handling arm 38 to the second rail 32 of the left slide assembly 22.

From the above description, it can be seen that the enhanced efficacy and advantages of the present invention are:

(1) the elastic member 50 of the first connecting device 26 is attached to one of the first fitting 46 and the second fitting 48, and when the first fitting 46 is assembled to the second fitting 48, the stop portion 50b is located at the other of the first fitting 46 and the second fitting 48 to prevent the first fitting 46 from being separated from the second fitting 48.

(2) The elastic portion 50a of the elastic member 50 has an opening 50c at a portion thereof, which facilitates the elastic member 50 to be easily pushed or operated by the external force F to accumulate the elastic force, i.e. the user can operate the elastic member 50 more easily and easily with less effort, so that the stopping portion 50b is deflected at an angle relative to the elastic portion 50a to facilitate the installation of the first fitting 46 and the second fitting 48.

(3) The first or second connection means 26, 28 may provide a mechanism for the slide rail and the wire management arm to be detachable from each other (e.g., the first and second

wire management arms

36, 30, 38, 32).

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.
