[0034] This utility model proposes a wiring box 1000.

[0035] Please see Figures 1 to 7 In one embodiment of the present invention, the wiring box includes a box body 1 and a plurality of cable management rings 2. A connecting frame 11 is provided inside the box body 1, and a connecting side plate 12 is provided on each of the opposite sides of the connecting frame 11. Each cable management ring 2 is provided on the connecting frame 11 and connected to each connecting side plate 12.

[0036] In this embodiment, the wiring box can be applied to scenarios such as cloud computing data centers, industrial IoT, and 5G base station deployments. Combined with... Figure 1It should be noted that the wiring box in this application is a 4U height chassis, which can be equipped with 16 wiring boxes or adapter panels. The front end of the chassis 1 is provided with a connecting frame 11, and each of the opposite sides of the connecting frame 11 is provided with a connecting side plate 12. Each connecting side plate 12 and the connecting frame 11 form a U-shaped structure. The connecting frame 11 is connected to the side wall of the chassis 1 by means of snap-fit, bolt connection, etc. It is understood that the number of cable management rings 2 is not limited, and can be two, three, four, etc. In one embodiment, each connecting side plate 12 is connected to one cable management ring 2 for better management of external cables; in another embodiment, each connecting side plate 12 is connected to four cable management rings 2. The connection relationship between the cable management rings 2 and the connecting side plates 12 includes, but is not limited to, detachable connection methods such as screw fixing and snap-fit ​​connection. In one embodiment, the cable management ring 2 is provided with a mounting hole 51, and a screw passes through the mounting hole 51 and is fixed to the connecting side plate 12 to ensure that the cable management ring 2 is securely installed. In another embodiment, the cable management ring 2 is connected to the connecting side plate 12 via a sliding groove or a limiting member. The cable management ring 2 can be adjusted in position along the sliding groove and fixed by the limiting member. No limitation is set here.

[0037] The technical solution of this utility model involves placing multiple cable management rings 2 on opposite sides of the enclosure 1. Compared to placing the cable management rings 2 on the enclosure cover, this allows maintenance personnel to directly access the cables during repairs, eliminating the need for frequent opening and closing of the enclosure cover, thus reducing maintenance complexity and time costs. Furthermore, since the cable management rings 2 are positioned on opposite sides of the enclosure 1, it facilitates cabling according to the specified bending radius, preventing cable damage caused by excessively small bending radii and better protecting the cable's bending radius. This arrangement improves maintenance convenience, thereby enhancing the overall cabling quality and reliability.

[0038] In one embodiment of this utility model, each connecting side plate 12 has a plurality of spaced limiting protrusions 121 at its end, and a limiting groove is formed between each pair of adjacent limiting protrusions 121. A limiting hole 122 is provided on the side wall of the limiting groove. Each cable management ring 2 includes a ring body 21 and a connecting buckle 22. The connecting buckle 22 protrudes from the ring body 21. A limiting groove 211 is provided on the periphery of the ring body 21. Each limiting protrusion 121 is limited in the limiting groove 211. The connecting buckle 22 is engaged with the limiting hole 122.

[0039] In this embodiment, combined with Figure 2 , Figure 3 and Figure 5The connecting side plate 12 and the cable management ring 2 are connected by a snap-fit ​​mechanism for quick installation and disassembly. It is understood that the number of limiting protrusions 121 is related to the number of cable management rings 2; every two adjacent limiting protrusions 121 connect to form a limiting groove, within which the cable management ring 2 is confined. A connecting buckle 22 is located at one end of the ring body 21 and protrudes from it, resembling a hook. It should be noted that the connecting buckle 22 can be a single hook or two hooks facing each other; here, two hooks facing each other are preferred for better engagement with the limiting holes 122. Specifically, to improve connection stability, two connecting buckles 22 protrude from one end of each ring body 21, and two limiting holes 122 are formed on the side wall of the corresponding limiting groove, with each connecting buckle 22 corresponding to one limiting hole 122. To ensure a tighter connection between the cable management ring and the connecting side plate 12, a limiting groove 211 is provided on the periphery of the cable management ring 2. A limiting protrusion 121 is correspondingly provided with the limiting groove 211, and the two are interlocked. It can be understood that, for aesthetic purposes, the depth of each limiting groove, i.e., each limiting protrusion 121, is aligned with the end of the cable management ring 2 after the interlocking mechanism. This design allows for quick installation and removal of the cable management ring 2, greatly improving operational efficiency.

[0040] In one embodiment of the present invention, the end of the cable management ring 2 away from the connecting side plate 12 is provided with a cable management opening 23, and the periphery of the cable management opening 23 is gradually narrowed.

[0041] In this embodiment, combined with Figure 2 It should be noted that the periphery of the thread outlet 23 is tapered, that is, the periphery of the thread outlet 23 is tapered along... Figure 2 The cable is tilted in the X direction, which can limit the range of cable movement and make it less likely for the cable to come loose; at the same time, the periphery of the cable management port 23 is tapered, which can better guide the cable into the cable management ring 2, making the cable easier to organize and fix.

[0042] In one embodiment of this utility model, the inner wall of the cable management ring 2 is provided with an arc-shaped curved surface.

[0043] In this embodiment, combined with Figure 2 To protect the cable, the inner wall of the cable management ring 2 is designed with an arc-shaped surface, which can better fit the shape of the cable and provide more uniform support, so that the cable can smoothly transition on the cable management ring 2 and prevent the cable from being damaged due to excessive local stress.

[0044] In one embodiment of this utility model, each connecting side plate 12 has five spaced-apart limiting protrusions 121 at its end, and a limiting groove is formed between each pair of adjacent limiting protrusions 121. Each limiting groove has two limiting holes 122 on its sidewall. Each cable management ring 2 includes two connecting buckles 22 and a ring body 21. A limiting groove 211 is formed on the periphery of the ring body 21. Both connecting buckles 22 protrude from the ring body 21 and are arranged on the same side. Each limiting protrusion 121 is limited within the limiting groove 211. The two connecting buckles 22 are respectively engaged with the two limiting holes 122.

[0045] In this embodiment, combined with Figure 3 and Figure 4 It should be noted that the connecting buckle 22 is preferably arranged in the form of two hooks facing each other, so as to better engage with the limiting hole 122. At the same time, in order to improve the connection stability between the cable management ring 2 and the connecting side plate 12, the two connecting buckles 22 of one cable management ring 2 are connected to the two limiting holes 122 of the connecting side plate 12. To make full use of the space in the wiring box, this embodiment is a refinement of the above embodiment, and will not be described in detail here. This achieves a compact arrangement of the wiring box, realizing a high-density solution.

[0046] In one embodiment of the present invention, the box body 1 further includes a drawer plate 3. One end of the drawer plate 3 near the side wall of the box body 1 is provided with a first guide rail 31. The inner side wall of the box body 1 is provided with a second guide rail 13. The second guide rail 13 is slidably connected to a third guide rail 14. The third guide rail 14 is slidably connected to the first guide rail 31 so that the drawer plate 3 can move relative to the box body 1.

[0047] In this embodiment, to facilitate the maintenance and management of equipment or cables within the wiring box, a pull-out panel 3 is slidably connected to the inner side wall of the box body 1. It is understood that, in conjunction with... Figure 1 The connecting frame 11 is connected to the drawer plate 3 by means of snap-fit, bolt connection, etc. Figure 6 As can be seen, to facilitate connection with the drawer 3, the drawer 3 has a side plate, and the first guide rail 31 is connected to the side plate of the drawer 3 by bolts, screws, or other means. The inner wall of the housing 1 is fixedly connected to the second guide rail 13 by bolts, threads, or other means. A third guide rail 14 is slidably mounted on the second guide rail 13, and the shape of the third guide rail 14 matches the shape of the first guide rail 31. Due to the presence of the third guide rail 14, it can be stretched into three sections, allowing the drawer 3 to be stretched a longer distance within a limited space. The above arrangement, through the sliding connection of the guide rails, allows the drawer 3 to be easily pulled out or pushed in from the housing 1, facilitating the maintenance and management of the equipment or cables inside the housing.

[0048] In one embodiment of the present invention, the fixed end of the second guide rail 13 is provided with a stop protrusion 15, and the third guide rail 14 abuts against the stop protrusion 15.

[0049] In this embodiment, combined with Figure 7 To prevent the second guide rail 13 from detaching from the third guide rail 14, a stop protrusion 15 is provided at the fixed end of the second guide rail 13. The stop protrusion 15 abuts against the corresponding structure of the third guide rail 14. The stop protrusion 15, through its shape and position, mechanically limits the movement range of the third guide rail 14, preventing it from detaching from the second guide rail 13. This arrangement increases the stability of the guide rail connection, prevents the guide rails from detaching due to external forces, and improves the overall structural reliability.

[0050] In one embodiment of the present invention, the wiring box further includes an unlocking spring 4. A through hole is provided on one side of the box body 1. One end of the unlocking spring 4 is connected to the draw plate 3, and the other end of the unlocking spring 4 is confined within the through hole.

[0051] In this embodiment, combined with Figure 1 and Figure 6 To facilitate quick unlocking of the drawer 3, one end of the drawer 3 is equipped with an unlocking spring 4. The unlocking spring 4 achieves locking and unlocking functions through its elastic deformation. When the spring is pressed, it elastically deforms, unlocking the connection between the drawer 3 and the housing 1; after releasing the spring, it returns to its original shape, relocking the drawer 3. It can be understood that the end of the unlocking spring 4 confined within the through hole forms a bent section, which, combined with... Figure 8 The end of the unlocking spring 4 that is connected to the drawer plate is a bent section 41. Part of the structure of the bent section 41 is connected to the drawer plate 3 by means of bolt connection, threaded connection, etc. The side of the bent section 41 facing away from the inside of the box forms a handle, which makes it easy for the user to operate the unlocking spring 4.

[0052] In one embodiment of the present invention, the housing 1 is provided with four module box modules 5 arranged in an array. Each module box module 5 includes four module boxes. The module boxes are arranged in an array along the extension direction of the housing 1. Each module box has a mounting hole 51 on one side. The connecting bracket 11 has a connecting hole 111 corresponding to each module box. The connecting hole 111 is set to correspond to the mounting hole 51.

[0053] In this embodiment, combined with Figure 1 and Figure 3To efficiently utilize the space within the wiring box, the module boxes are arrayed along the extension direction of the enclosure 1, improving space utilization. It should be noted that enclosure 1 is a 4U height chassis, capable of accommodating 16 wiring boxes or adapter panels. For ease of subsequent maintenance of module box 5, module box 5 is mounted on connecting bracket 11, which in turn is mounted on drawer plate 3. Drawer plate 3 is slidably connected to enclosure 1, allowing module box 5 to move as drawer plate 3 slides. The module box and connecting bracket 11 are connected by fasteners that pass sequentially through mounting holes 51 and connecting holes 111. These fasteners include, but are not limited to, bolts and rivets; plastic rivets are preferred, with their expanded tails securing the connecting bracket 11 and module box. This setup is simple to operate, requires no complex tools, and facilitates quick installation and disassembly.

[0054] In one embodiment of the present invention, the box body 1 further includes a box cover, which is located at the front end of the box body 1 and is snapped into the box body 1.

[0055] In this embodiment, combined with Figure 1 (Lid not shown) To effectively prevent external dust and moisture from entering the interior of enclosure 1, a lid is provided to improve the airtightness of enclosure 1. Simultaneously, the lid is snap-fitted to enclosure 1, ensuring its stable position. This design allows for quick installation and removal of the lid, facilitating maintenance and management of the interior of enclosure 1.

[0056] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
