Technical Field

[0001] The present application relates to the technical field of communication network equipment, and in particular to an optical cable fixing layer plate and a junction box. Background Art

[0002] In the cabinets of communication network equipment, there are many electronic devices used for communication, such as switches, routers, servers, power supply equipment, etc. They work together to ensure the efficient transmission of optical signals in the network. Optical cables are communication cables used to transmit optical signals. When used, they need to be introduced from the outside into the cabinet and connected to the servers in the cabinet. Since there are usually multiple servers inside the cabinet, in order to avoid messy optical cable routing, the optical cables need to be fixed and managed before being distributed to connect to each server.

[0003] Cabinets generally contain optical cable holders for fixing incoming optical cables. Traditional optical cable holders are generally set at the top or bottom of the cabinet and are flat optical cable mounting plates. Since the optical cable mounting plates need to be fixed inside the cabinet, the optical cable fixing area that traditional optical cable mounting plates can provide is very limited. However, with the rapid development of the optical fiber cabling industry, the optical fiber capacity in the cabinet is getting larger and larger, and the density is getting higher and higher. The existing optical cable fixing methods can hardly meet the capacity requirements of modern cabinets. Utility Model Content

[0004] In order to improve the situation that the existing optical cable fixing method is difficult to meet the optical fiber capacity requirements of modern cabinets, the present application provides an optical cable fixing layer plate and a junction box.

[0005] On the one hand, the present application provides an optical cable fixing layer plate, which adopts the following technical solution:

[0006] An optical cable fixing layer plate, comprising

[0007] A substrate, the substrate is placed vertically, connecting ribs are arranged at the edges of both sides of the substrate, the connecting ribs are perpendicular to the substrate, the two connecting ribs have the same width, and the substrate and the two connecting ribs together surround a receiving cavity with an opening for placing an optical cable;

[0008] A first connecting portion is provided at the top of the substrate away from the connecting rib, and a second connecting portion is provided at the top of the connecting rib. When a plurality of the optical cable fixing layers are combined, the first connecting portion of one of the optical cable fixing layers is overlapped and hung on the second connecting portion of another optical cable fixing layer, so that two adjacent optical cable fixing layers are combined into a whole. The plurality of the optical cable fixing layers are used to be stacked in layers along the depth direction of the cabinet, and the optical cable fixing layer located at the innermost layer is used to be detachably connected to the cabinet.

[0009] By adopting the above technical scheme, through the coordinated use of the first connecting part and the second connecting part, multiple optical cable fixing layers can be conveniently and quickly combined together to form a stable overall structure, which not only improves the installation efficiency of the optical cable fixing layer, but also enhances the stability of the overall structure; at the same time, since the optical cable fixing layer is detachable, it can be flexibly adjusted according to actual needs, which is convenient for capacity expansion and maintenance. Multiple optical cable fixing layers can be stacked in layers along the depth direction of the cabinet, so as to make full use of the internal space of the cabinet. When the number of optical cables in the cabinet is large, the number of layers of optical cable fixing layers can be increased according to the actual optical cable capacity requirements, and each optical cable is placed in different layers of optical cable fixing layers, so that even if the number of optical cables is large, they can still be layered and arranged by multiple layers of optical cable fixing layers, which is convenient for the routing of optical cables in the cabinet.

[0010] Optionally, the first connecting portion is a hook, which is bent downward in a direction away from the connecting rib, and a positioning groove is provided on the top of the second connecting portion. When a plurality of the optical cable fixing layers are combined, the first connecting portion of one of the optical cable fixing layers is overlapped and hung in the positioning groove of an adjacent optical cable fixing layer.

[0011] By adopting the above technical solution, the coordinated use of the hook and the positioning groove can conveniently and quickly combine multiple optical cable fixing layers to form a stable overall structure.

[0017] By adopting the above technical solution, the clamping ring structure can realize the rapid clamping and fixing of the optical cable, which not only improves the installation efficiency of the optical cable, but also enhances the stability of the optical cable in the accommodating cavity, and effectively prevents the loosening and falling off of the optical cable.

[0018] Optionally, the base plate and the connecting ribs are made of plastic material or alloy material.

[0019] By adopting the above technical solution, the base plate and the connecting ribs are made of plastic material or alloy material, which not only ensures the structural rigidity of the optical cable fixing layer plate itself, but also effectively reduces the weight of the optical cable fixing layer plate itself.

[0020] On the other hand, the present application provides a junction box, which utilizes an optical cable fixing layer as described in any one of the above items to organize optical cables, including a backplane, wherein the backplane is used to be vertically installed in the optical cable routing area of ​​the cabinet, and the optical cable fixing layer is detachably connected to the backplane. In the vertical or horizontal direction, the optical cable fixing layers are installed continuously or at intervals, and the backplane is penetrated by a plurality of groups of mounting holes, and each group of mounting holes is evenly spaced along the vertical direction. The mounting holes are used for detachable installation of the optical cable fixing layer, and multiple optical cable fixing layers are used to be stacked in layers along the depth direction of the cabinet.

[0021] By adopting the above technical solution, the design of the junction box fully utilizes the flexibility and stability of the optical cable fixing layer. Through the coordinated use of the back panel and the mounting holes, efficient cable management and management are achieved, which not only improves the neatness and management efficiency of the optical cable wiring in the cabinet, but also provides great convenience for subsequent expansion and maintenance work.

[0036] The following is combined with Figure 1-5This application is described in further detail.

[0037] Embodiment 1:

[0038] Embodiment 1 of the present application discloses an optical cable fixing layer plate, referring to Figure 1 and Figure 2 The optical cable fixing layer includes a base plate 11, which is placed vertically. Connecting ribs 12 are integrally formed at the edges of both sides of the base plate 11. The connecting ribs 12 are perpendicular to the base plate 11, and the two connecting ribs 12 have the same width. The base plate 11 and the two connecting ribs 12 together surround a receiving cavity 13 with an opening, and multiple optical cables can be placed side by side in the receiving cavity 13.

[0039] A first connection portion 111 is integrally formed at the top of the base plate 11 away from the connecting rib 12. The first connection portion 111 may be a hook, and the hook is bent downward in a direction away from the connecting rib 12. A second connection portion 121 is integrally formed at the top of the connecting rib 12, and a positioning groove 122 is provided at the top of the second connection portion 121.

[0040] When multiple optical cable fixing layers 1 are stacked in layers, the hook of one optical cable fixing layer 1 can be overlapped and hooked in the positioning groove 122 of the adjacent optical cable fixing layer 1, so that the two adjacent optical cable fixing layers 1 can be stably combined into a whole, and the positioning groove 122 facilitates the hook to quickly locate, thereby improving the installation efficiency. This design allows multiple optical cable fixing layers 1 to be stacked in layers along the depth direction of the cabinet, thereby making full use of the internal space of the cabinet and meeting the high-density requirements of modern communication equipment for optical cable fixing.

[0041] The bottom of the connecting rib 12 is integrally formed with a third connecting portion 123, and the third connecting portion 123 is penetrated with a first fixing hole 124, and the substrate 11 is also penetrated with a second fixing hole 112 at a position corresponding to the first fixing hole 124. When multiple optical cable fixing layers 1 are combined, the third connecting portion 123 of one optical cable fixing layer 1 will be tightly abutted against the substrate 11 of the adjacent optical cable fixing layer 1. At this time, the first fixing hole 124 and the second fixing hole 112 of the two adjacent optical cable fixing layers 1 will completely correspond. By penetrating and clamping the fixing member 2 in the corresponding first fixing hole 124 and the second fixing hole 112, the connection stability between the two adjacent optical cable fixing layers 1 can be further enhanced, which not only retains the flexibility and convenience of the original structure, but also greatly improves the durability and external force resistance of the structure. In embodiment 1 of the present application, the fixing member 2 is a plastic buckle, which can be clamped and fixed in the corresponding fixing hole. In other embodiments of the present application, the fixing member 2 can also be a fastening bolt.

[0042] Reference Figure 1 and Figure 3In order to better fix and organize the optical cable in the accommodating cavity 13, the side wall of the substrate 11 located in the accommodating cavity 13 is integrally formed with a positioning protrusion 113, and the positioning protrusion 113 is horizontally penetrated with a through groove 114, and the through groove 114 can be used to pass a cable tie, so that the optical cable 3 is bound to the positioning protrusion 113 by the cable tie to prevent the optical cable from loosening or shifting during transportation or use. In Example 1 of the present application, an optical cable fixing layer 1 can fix three optical cables 3 at the same time, and each optical cable 3 corresponds to four positioning protrusions 113, and two positioning protrusions 113 form a group. The same optical cable 3 corresponds to two groups of positioning protrusions 113 distributed at intervals. The optical cable is tightened with a cable tie, which effectively prevents the loosening and shifting of the optical cable, and improves the installation stability and use safety of the optical cable.

[0043] The implementation principle of an optical cable fixing layer plate in embodiment 1 of the present application is as follows: an optical cable 3 can be placed in the accommodating cavity 13 of the optical cable fixing layer plate 1, and a cable tie can be inserted into the through groove 114 to fix the optical cable 3. When one layer of optical cable fixing plate is not sufficient to meet the cable management needs, multiple optical cable fixing layers 1 of another layer of optical cable fixing plate can be overlapped and connected into a whole through the first connecting portion 111 and the second connecting portion 121 of the original layer of optical cable fixing layer plates 1, so that the optical cable fixing layers 1 can be stacked in multiple layers in the depth direction of the cabinet, thereby increasing the accommodating area for the optical cable 3 and making full use of the internal space of the cabinet to meet more optical fiber cable management needs.

[0044] Embodiment 2:

[0045] The difference between Example 2 and Example 1 is that: Figure 4 , a clamping ring 4 is integrally formed on the positioning protrusion 113, and the clamping ring 4 is provided with an opening 41, and the opening 41 faces the direction away from the substrate 11. At the same time, in Example 2 of the present application, each optical cable 3 corresponds to two positioning protrusions 113, and the two positioning protrusions 113 are spaced apart along the length direction of the optical cable 3. When the optical cable 3 needs to be installed on the optical cable fixing layer 1, the optical cable 3 only needs to be aligned with the opening 41 and pressed, and the optical cable 3 can be directly pressed into the clamping ring 4, so as to realize the rapid clamping and firm fixation of the optical cable, further improve the installation efficiency and stability of the optical cable, and effectively prevent the optical cable from falling off and being damaged.

[0046] Embodiment 3:

[0047] Embodiment 3 of the present application discloses a junction box, which utilizes the optical cable fixing layer plate in Embodiment 1 and Embodiment 2 to organize the optical cables. Figure 5 The junction box 5 includes a back plate 51 , which can be vertically installed in the optical cable routing area of ​​the cabinet, and the optical cable fixing layer plate 1 can be detachably connected to the back plate 51 .

[0048] There are multiple groups of mounting holes on the back plate 51, and the mounting holes of each group are evenly spaced in the vertical direction. These mounting holes are used for detachable installation of the optical cable fixing layer 1. Specifically, each group of mounting holes includes a row of square holes 511 and a row of round holes 512, wherein the square holes 511 are spaced apart in the horizontal direction for the first connecting portion 111 of the optical cable fixing layer 1, i.e., the hook to pass through and overlap. The round holes 512 are spaced apart below the square holes 511, and are also spaced apart in the horizontal direction. These round holes 512 can be used for positioning the substrate 11, and can be passed through and clamped by fixing parts 2, such as plastic buckles.

[0049] With this design, the optical cable fixing layer plate 1 can be conveniently installed at any position in the optical cable routing area of ​​the cabinet through the installation holes on the back plate 51 according to actual needs. When there is a need for expansion, just take an optical cable fixing layer plate 1, hang its hook on the square hole 511 on the back plate 51, and then align the second fixing hole 112 of the base plate 11 with the round hole 512 therein, and press the pull buckle therefrom to complete the installation. Multiple optical cable fixing layers 1 can be stacked in layers along the depth direction of the cabinet, thereby making full use of the space in the depth direction of the cabinet and meeting the use requirements of a high-density cabinet.

[0050] At the same time, due to the detachable connection design between the optical cable fixing layer plate 1 and the back plate 51, it is also very convenient during maintenance. Just pull out the draw buckle of the optical cable fixing layer plate 1 that needs maintenance, and then disengage the hook upwards to carry out maintenance and replacement operations of the optical cable.

[0051] The implementation principle of a junction box in Example 3 of the present application is as follows: by opening an installation hole on the back panel 51 of the junction box 5 to install the optical cable fixing layer 1, the optical cable fixing layer 1 can be used to perform layered cable management and layered management, thereby achieving efficient organization and protection of the optical cables in the cabinet, which not only improves the cleanliness and aesthetics of the cabinet, but also provides great convenience for subsequent expansion and maintenance work, and reduces maintenance costs and time costs.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
