As shown in Figure 1A, the back bracket 1 of the present invention is a beam structure, fixed at the position near the rear side wall of the cabinet, and each layer of servers corresponds to a double-layer cable management device, respectively For separate cable management of each server, the back support 1 of the multi-layer server can adopt an integrated design, and the cable management arm frame 2 of each layer is separately set.

As shown in FIG. 2A and FIG. 2B , they are respectively the expanded state structure diagram and the folded state structure diagram of the mutual assembly of the cable management arm frame 2 and the slide rail 3 of the present invention, and A in the figure represents the cable; the cable management arm frame 2 includes at least Two cable management arms 21, the outer end of the outermost cable management arm 21 is hinged to the inner rail 31 of the slide rail 3 or the server shell, and the outer side is the side where the server is pulled out. 21 is driven by the server. When the server moves, it drives the outermost cable management arm 21 to move, and then drives other cable management arms 21 to move. When the server is pulled out, the length of the entire cable management arm 2 increases, and the server is pushed back. During this time, the length of the whole cable management arm frame 2 is shortened.

Each cable management arm 21 is respectively provided with a wire binding buckle 22 for binding the cable, and the cable and the wire management arm 21 are relatively fixed by the wire binding buckle 22, so that the cable moves synchronously with the wire management arm 21. When the server When pushed back inward, the cable is folded synchronously with the cable management arm 21 .

As shown in FIG. 3 , it is a structural schematic diagram of the cooperation between the cable management arm 2 and the slide rail 3 , and the figure shows the positions of the cable management arm 2 in two states. Each root wire management arm 21 is mutually hinged, and two adjacent wire management arms 21 form a group. In the accompanying drawings of the application, four wire management arms are taken as an example, and they are divided into two groups. The two cable management arms 21 do not overlap in the height direction, and are divided into upper and lower layers. In the folded state, the two cable management arms 21 of the same group occupy the thickness of one cable management arm 21. There are four cable management arms in two groups 21 In the folded state, it only takes up the thickness of two cable management arms. Using the vertical space, compared with the traditional cable management structure, the thickness is reduced by half under the same extension length, which can effectively save the space inside the cabinet.

It should be noted that only two layers of cable management arms are provided in the drawings of this application. If necessary, three or more cable management arms can be used as a group. The understanding arms in the same group are staggered without overlapping.

On the basis of the above-mentioned scheme, the present invention fixes the lower layer stop block 11 on the back bracket 1, which is used to block the lower layer cable management arm 21 when folding. When folding and shrinking, the innermost lower layer cable management The arm 21 first contacts the lower stop block 11, and cannot continue to rotate backwards when it is blocked, so that the lower cable management arm is kept parallel to the back bracket 1, and the outer lower layer cable management arm 21 is in contact with the inner lower layer cable management arm 21. , limit all the lower layer management lines one by one.

One of the cable management arms 21 located on the upper layer is provided with an upper stop block 25, as shown in Figure 1A, the upper layer stop block 25 is arranged on the upper layer of the cable management arm 21 in the outer group, the drawings only show In a specific solution, it can also be arranged on the upper layer cable management arm 21 in the inner group.

The upper floor stop block 25 can contact with the wire management arm 21 of the lower floor, and is used to block the wire management arm 21 of the upper floor when folding, and the wire management arm 21 of the lower floor is first blocked by the lower floor stop block 11. The wire arm 21 is further blocked and limited by the wire management arm 21 of the lower layer.

Specifically, in the present invention, the two wire management arms 21 in the same group are connected through the same rotating shaft 23, because the two wire management arms 21 in the same group do not overlap in the pulling direction, so there is no interference between them, and it can Commonly connected to the same shaft. In the adjacent two groups of cable management arms, a hinge block 4 is arranged between the cable management arms 21 on the same floor, and two rotating shafts are arranged side by side on the hinge block 4, which are respectively hinged with two cable management arms 21 of different groups, as As shown in the drawings, the cable management arms 21 of the same layer in two adjacent groups are hinged to each other. In order to prevent interference, the hinge block 4 needs to be used as a connection.

A spacer 24 is arranged between the two wire management arms 21 of the same group, and the spacer 24 is set outside the rotating shaft 23, and is used to separate the two wire management arms 21 of the same group by a certain distance, further preventing each wire of the same group from The cable management arms 21 interfere with each other.

On the basis of any of the above-mentioned technical solutions and their mutual combinations, the outer end of the outermost cable management arm 21 of the present invention is connected to the quick-release terminal 26, as shown in FIG. Partial schematic diagram of mutual cooperation of the detachable terminals 26; FIG. 4B is a structural diagram of the quick-detachable terminal 26; the quick-detachable terminal 26 is bent at a right angle, one of the plates is hinged with the cable management arm 21, and the other plate is passed through the inner rail 31 The finger screw is screwed and fixed, and the quick release terminal 26 is relatively fixed to the inner rail 31 , so the cable management arm 21 is indirectly hingedly connected to the inner rail 31 through the quick release terminal 26 .

Furthermore, in the present invention, hinges 12 are respectively hinged at both ends of the back support 1, and the hinges 12 are arranged perpendicular to the back support 1 approximately, and are attached to the side walls of the cabinet.

The end of the outer rail 32 of the slide rail 3 is provided with a clamping head 33, and the two side edges of the clamping head 33 are inserted into the pressing block 121 to slide, and an opening is set in the middle of the clamping head 33. When the clamping head 33 is inserted in place, the elastic piece 122 can be locked Insert it into the opening in the middle of the chuck 33 to realize the locking connection; when it needs to be separated, press the spring 122, and then reversely pull out the outer rail 32 to realize the effect of quick plug-in connection.

Specifically, the present invention sets waist-shaped holes 27 in pairs on the wire management arm 21. The length direction of the waist-shaped holes 27 is consistent with the length direction of the wire management arm 21. The wire binding buckle 22 is a flat belt-shaped structure. The wire buckle 22 passes through the two waist-shaped holes 27 at the same time to form a ring structure, so that the wire-binding buckle 22 binds the cables. The wire-binding buckle 22 can be in the form of Velcro or the like.

The present invention also provides a server cabinet, which includes any one of the above-mentioned double-layer cable management devices, and the server cabinet can achieve the same technical effect.
