Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a multi-layer switch for network management. Background Technology

[0002] With the rapid development of communication technology, multilayer switches, as core data switching equipment, have been widely used in various network communication systems. Currently, there are two main installation methods: standardized rack mounting and simple stacking in computer rooms or office environments. While standardized rack mounting ensures sufficient spacing between devices, provides good heat dissipation, and facilitates cable management, it requires dedicated racks and accessories, resulting in higher procurement and maintenance costs and greater space requirements for enterprises. To save on deployment expenses, many small and medium-sized projects prefer the simpler method of stacking equipment.

[0003] However, existing stacking installation methods still have several obvious defects in practical applications. For example, patent CN214481907U discloses a communication switch cabinet. This solution sets up a support frame structure at each switch in the cabinet to support the cables and wiring harnesses. Its design purpose is to ensure the stability and safety of the cables through a multi-layer support structure.

[0004] However, the communication switch cabinet disclosed in this patent document has significant defects in its support frame structure: it relies on the sliding fit between the right-angle buckle plate and the right-angle base plate and the locking of the nut to adjust the height to support the cable. This structure is prone to stripping or loosening when bearing the weight of the cable for a long time, resulting in the failure of the adjustment function; its wire harness frame uses a simple plug-in method of fin slots and plug plates to fix the wire harness. This mechanical connection method has limited binding force and is a point contact, which makes it difficult to evenly support the weight of the wire harness. Under long-term gravity, it is very easy to cause the plug plate to loosen, the fins to deform or break completely, and it still cannot fundamentally avoid the problems of cable sagging and connection stability.

[0005] In addition, existing stacking solutions generally lack professional cable fixing mechanisms. Network cables rely solely on the friction between the RJ45 connector and the port to maintain the connection. In actual operation, this can easily lead to displacement due to equipment movement, maintenance operations, or accidental external pulling, resulting in poor port contact and thus affecting the reliability and performance stability of network transmission.

[0006] Therefore, there is an urgent need for a switch installation solution that is structurally robust, easy to maintain, can effectively manage cables, and also meets heat dissipation requirements. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a multi-layer switch for network management, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A multilayer switch for network management includes a chassis body. A stacking docking assembly is symmetrically mounted on the top surface of the chassis body, and a load-bearing slide rail assembly is symmetrically mounted on the bottom surface of the chassis body. The load-bearing slide rail assembly is slidably connected to the stacking docking assembly. A cable clamp management assembly is mounted at one end of the bottom surface of the chassis body. A core switching assembly is installed inside the chassis body. The stacking docking assembly includes a track. The track is symmetrically mounted on the top surface of the chassis body. A T-shaped interlocking slide is provided at one end of the top surface of the track. Countersunk holes are evenly spaced at the bottom of the inner cavity of the T-shaped interlocking slide, and fastening bolts are installed in the countersunk holes. A reset damping rod is fixedly connected to one side of the track. A pull rod is fixedly connected to one end of the reset damping rod, and a limiting pin is fixedly connected to one side of the pull rod. One end of the limiting pin passes through the track and slides within the T-shaped interlocking slide.

[0010] This invention provides a multi-layer switch for network management. Compared with the prior art, it has the following advantages:

[0011] 1. To solve the problems of unstable stacking installation of existing switches, lack of effective positioning, and impact on heat dissipation, this utility model completes the installation by cooperating the load-bearing slide rail assembly located at the bottom of the chassis body and the stacking docking assembly located at the top. During installation, the I-shaped rod of the upper switch is precisely inserted into the T-shaped fitting slide of the lower switch, and the initial docking and load-bearing can be achieved by horizontal sliding.

[0012] To ensure absolutely reliable connection, a limit pin mechanism driven by a reset damping rod is designed. The operator pulls the lever outward to overcome the damping force of the reset damping rod, causing the limit pin to retract from the T-shaped interlocking slide. After the I-shaped rod slides into place, the lever is released, and the limit pin, pushed by the reset damping rod, precisely inserts into the locking hole on the side of the I-shaped rod, forming a mechanical interlock. This effectively prevents lateral displacement or detachment of the equipment during vibration or handling. This creates a regular elevated layer, forming a natural ventilation duct, completely avoiding heat accumulation caused by stacking solid objects and improving heat dissipation efficiency.

[0013] 2. Through the design of the cable clamp management component, the cable harness connected to the switch is clamped and fixed to prevent the cable harness from being pulled, so that the RJ45 connector and the switch port maintain stable contact. This effectively prevents cable displacement caused by human movement, equipment maintenance or accidental pulling, improves network transmission performance, solves the problem of unstable cable harness fixing in existing multi-layer switches, and ensures the reliability and stability of network connection.

[0014] 3. To address the issues of low internal heat dissipation efficiency, inconvenient module maintenance, and limited installation options in switches, this invention firstly incorporates large ventilation grilles on both sides of the main chassis. These grilles work in conjunction with the airflow created during stacking to form a highly efficient passive cooling system, ensuring natural air convection and effectively removing heat generated by the main control board and ports during operation. Secondly, the core switching components (including the U-shaped board, main control board, RJ45 ports, power interfaces, etc.) are designed as an independent, sliding module installed inside the main chassis. For maintenance, the entire module can be removed from the chassis, allowing for easy inspection of the front and rear ports and motherboard without touching the cables. Finally, L-shaped mounting brackets are added to both sides of the chassis, enabling rapid stacking of the equipment using the stacking docking components and load-bearing slide rails, or reliable mounting to the uprights of a standard cabinet using the L-shaped brackets, achieving full coverage of application scenarios.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] To address the technical problems in the background section, the following multilayer switch for network management is proposed:

[0033] Combination Figure 1 - Figure 7 As shown, the present invention provides a multi-layer switch for network management, including a chassis body 100, a stacking docking assembly 200 symmetrically installed on the top surface of the chassis body 100, a load-bearing slide rail assembly 300 symmetrically installed on the bottom surface of the chassis body 100, the load-bearing slide rail assembly 300 being slidably connected to the stacking docking assembly 200, a wire clamp management assembly 400 installed at one end of the bottom surface of the chassis body 100, and a core switching assembly 500 installed inside the chassis body 100.

[0034] In this embodiment, the stacking docking assembly 200 includes a track 201. The track 201 is symmetrically mounted on the top surface of the main body 100. A T-shaped fitting slide 202 is provided at one end of the top surface of the track 201. Countersunk holes 203 are evenly spaced at the bottom of the inner cavity of the T-shaped fitting slide 202, and fastening bolts 204 are installed in the countersunk holes 203. A reset damping rod 205 is fixedly connected to one side of the track 201. A pull rod 206 is fixedly connected to one end of the reset damping rod 205, and a limiting pin 207 is fixedly connected to one side of the pull rod 206. One end of the limiting pin 207 passes through the track 201 and slides within the T-shaped fitting slide 202. It can be understood that the reset damping rod provides stable support when the limiting pin 207 moves, preventing the limiting pin 207 from shifting during movement, thereby improving the accuracy and reliability of the docking.

[0035] In this embodiment, the load-bearing slide rail assembly 300 includes an I-shaped rod 301. The I-shaped rod 301 is symmetrically installed on the bottom surface of the main body 100 of the chassis. Fixing screw holes 302 are provided at equal intervals on one side of the I-shaped rod 301. Locking bolts 303 are placed in the fixing screw holes 302. Locking holes 304 are provided on one side of the I-shaped rod 301.

[0036] Based on the above technical concept, it can be understood that by cooperating with the load-bearing slide rail assembly 200 and the stacking docking assembly 300, multiple sets of switches can be stacked and connected together. When connecting, a gap is left between the two to avoid heat transfer between them, thereby affecting heat dissipation and the operation of the switches.

[0037] In this embodiment, the cable clamp management component 400 includes a support arm 401. The support arm 401 is fixedly connected to the bottom surface of the chassis body 100 by bolts. One end of the support arm 401 is fixedly connected to a cable holder 402. Main cable routing channels 403 are respectively provided on both sides of the cable holder 402. Cable clamping covers 404 are fixedly connected to both sides of the cable holder 402 by bolts. Auxiliary cable routing channels 405 are provided at equal intervals on one side of the cable clamping cover 404.

[0038] The cable management component 400 can clamp and fix the cable harness connected to the switch, preventing the cable harness from being pulled and causing the RJ45 connector to become loose or detach from the switch port.

[0039] In this embodiment, the core switching component 500 includes a U-shaped board 501, which is slidably connected inside the chassis body 100. RJ45 ports 502 are evenly spaced on one side of the U-shaped board 501, and indicator lights 503 are installed on one side of the U-shaped board 501, located next to the RJ45 ports 502. In addition, the core switching component 500 also includes a main control board 504, a power interface 505, and a power switch 506. The main control board 504 is fixedly connected to the middle of the U-shaped board 501, the power interface 505 is installed on the other side of the U-shaped board 501, and the power switch 506 is installed on the other side of the U-shaped board 501, located next to the power interface 505. It is understood that the design of the U-shaped board 501 allows the core switching component 500 to slide flexibly, facilitating maintenance and replacement.

[0040] In this embodiment, ventilation grilles 600 are provided on both sides of the chassis body 100, and L-shaped mounting ears 700 are fixedly connected to both sides of the chassis body 100 by bolts. The ventilation grilles 600 allow for ventilation and heat dissipation of the electrical components inside the switch; while the L-shaped mounting ears 700 on both sides of the switch facilitate subsequent installation of the switch inside the chassis. In practical applications, it is preferable that the bottom of the chassis body 100 is provided with a shock-absorbing pad made of rubber to reduce vibration of the heat dissipation mechanism, reduce noise, and minimize the risk of failure due to vibration.

[0041] Working principle and usage process of this utility model:

[0042] A multi-layer switch can be assembled from the main chassis and the core switching component 500. The multi-layer switch model is S5735S-L24FT4S-A switch.

[0043] When multiple switches need to be stacked vertically or installed on an external mounting rack, simply install the load-bearing slide rail assembly 300 on the switch and the stacking docking assembly 200 on the external mounting rack or the next switch to easily stack two switches vertically or install the switch on an external mounting rack.

[0044] When equipment stacking or rack mounting is required, first install the load-bearing slide rail assembly 300 at the bottom of the equipment. During installation, the I-beam 301 should be pressed against the side of the main body 100 of the chassis, aligning the fixing screw holes 302 with the screw holes on the chassis, and screwing in the locking bolts 303 to complete the fixation. Then install the stacking docking assembly 200. Attach the rail 201 to the top of the equipment to be installed or the surface of the mounting bracket, aligning the countersunk holes 203 with the screw holes below, and use the fastening bolts 204 to secure it firmly.

[0045] After the installation of both components is completed, the docking operation can be performed. Pull the pull rod 206 outward, and the reset damping rod 205 will drive the limit pin 207 to disengage from the T-shaped fitting slide 202. Align the I-shaped rod 301 of the upper device with and insert it into the T-shaped fitting slide 202 of the lower device. Once in place, release the pull rod 206, and the reset damping rod 205 will push the limit pin 207 into the locking hole 304 of the I-shaped rod 301, completing the mechanical locking and achieving stable stacking or installation.

[0046] When wiring is performed after the equipment connection is completed, insert all network cable connectors into the corresponding RJ45 ports 502. Place the cables orderly into the main cable tray 403 of the cable holder 402, cover with the cable clamping cover 404 and tighten with bolts. The main cable tray 403 and the auxiliary cable tray 405 together clamp and fix the cables, eliminating the influence of external stress on the port connection.

[0047] As an embodiment of this utility model, the chassis body 100 is preferably made of aluminum alloy and has dimensions of 500mm in length × 300mm in width × 100mm in height, so as to improve the strength and durability of the overall structure.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
