[0029] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0031] Server chassis contain a large number of cables used to connect various circuit boards and modules for signal transmission and power supply. With increasing signal speeds and system modularization, the number and diameter of cables are constantly increasing, placing higher demands on cabling management. Simultaneously, rising chip power consumption leads to increased heat generation, making the internal airflow design of the chassis increasingly critical, ensuring unobstructed airflow for effective heat dissipation. Therefore, cable routing must not only avoid compressing or pulling damage to circuit boards or components but also prevent cables from crossing main airflow channels, thus affecting heat dissipation performance.

[0032] Currently, there are two main methods for securing cables: First, adhesive-backed cable clips, which are easy to install, but the adhesive is susceptible to failure due to high temperatures, causing the clips to detach. Residual adhesive can remain after disassembly, affecting maintenance, reuse, and recycling after equipment retirement. Second, screw-mounted cable clips, which are structurally stable, rely on screws and studs for fixing, making installation and disassembly time-consuming and increasing assembly time. They also require openings in the circuit board, limiting layout design, posing a risk of damage during mounting, and increasing component and assembly costs.

[0033] To address the aforementioned issues, this application provides a cable management structure that reliably secures cables without relying on adhesive or screws. It offers advantages such as easy installation and disassembly, no damage to circuit boards, and no obstruction of internal airflow within the chassis. This effectively improves the reliability and maintainability of server internal cabling.

[0034] Example 1

[0035] This application provides a cable management structure, such as... Figures 1 to 4 As shown, and Figure 10 As shown, it includes: a stop 1 having a cable management space A for restricting cable movement; and a snap-fit ​​2 connected to the stop 1 for insertion between multiple functional layers. When the stop 1 is subjected to a load force from the cable in a first direction C, the snap-fit ​​2 remains in contact with the functional layers, thereby achieving a locked state. When the stop 1 is subjected to a load force in a second direction D, the snap-fit ​​2 disengages from the functional layers, thereby achieving an unlocked state.

[0036] The cable management structure provided in this application embodiment can be applied to server chassis, storage device chassis, industrial control cabinets, etc. The cable management structure includes a stop 1 and a snap-fit ​​component 2, which can be integrally formed with the stop 1 or fixedly connected.

[0037] The stop 1 has a cable management space A for accommodating and restricting the movement of data cables, power cables, and other cables. The cable management space A can be a U-shaped groove, L-shaped groove, Z-shaped groove, annular hole, or other structure suitable for cable bundling, effectively limiting and organizing single or multiple cables. The shape of the latch 2 can be adapted to the gap between adjacent functional layers within the chassis. These functional layers can be circuit boards, brackets, guide rails, trays, or other components with structural support functions.

[0038] When the stop 1 is subjected to a load force from the wire along the first direction C, such as the restoring force of the wire due to bending deformation, the pushing force applied by other components, or a manually applied force, the load force is transferred to the latch 2. Under its action, the latch 2 will press tightly against the upper and lower functional layers to generate sufficient friction or mechanical interference, thereby entering a locked state and preventing the wire management structure from falling off the functional layers. When disassembly is required, a load force along the second direction D can be applied to the stop 1. The second direction D can be opposite to the first direction C. This allows the latch 2 to elastically deform or detach from the contact with the functional layers, reducing or eliminating friction or mechanical interference, thus allowing the latch 2 to be smoothly pulled out from the gap between the functional layers, achieving the unlocked state.

[0039] The cable management structure provided in this application utilizes the gaps between existing functional layers within the electronic device for installation, eliminating the need for additional studs or holes in the circuit board. The locking mechanism between the snap-fit ​​component 2 and the functional layer not only replaces traditional adhesive bonding or screw fastening methods, solving problems such as adhesive aging and failure under high-temperature environments, residual adhesive contamination, and stud drilling damage to the circuit board, but also enables manual installation and disassembly without tools. This simplifies operation, significantly reduces assembly and maintenance time, and improves operational efficiency.

[0040] In some embodiments, the stop 1 includes a wall 101, which is able to form an angle with the functional layers when the snap-fit ​​2 is inserted between multiple functional layers. The wall 101 forms a cable management space A on the side of the functional layer that is away from the functional layer with the functional element 6. The wall 101 includes a first side and a second side that are arranged opposite to each other along its length. The cable can enter the cable management space A from the first side and be led out from the second side. The wall 101 is used to resist the movement tendency of the cable along the first direction C. The first direction C is the direction that extends toward the side of the functional layer with the functional element 6, and the second direction D is opposite to the first direction C.

[0041] Stop 1 includes wall 101, such as Figures 1 to 6 As shown, the wall 101 can be a frame structure or a panel structure. When the snap-fit ​​2 is inserted between adjacent functional layers, the wall 101 and the functional layer form a certain angle, that is, the wall 101 is inclined or vertically set on the surface of the functional layer.

[0042] In this embodiment, the functional layer consists of a motherboard and a tray. The motherboard is equipped with functional components 6, such as electronic components, interfaces, and connectors. The tray is located on the side of the motherboard facing away from the functional components 6 and serves to support and protect the motherboard. The wall 101, facing away from the motherboard where the functional components 6 are located, forms a cable management space A for accommodating and positioning cables. Specifically, the wall 101 can organize cables to the edge of the motherboard and restrict their movement towards the side of the motherboard with the functional components 6. The wall 101 has opposing first and second sides along its length. Cables can enter the cable management space A from the first side, be guided, and then exit from the second side, achieving orderly cable routing. Figure 9 and Figure 10 As shown, the first direction C is defined as the direction toward the side of the functional layer with functional component 6, and the second direction D is the opposite direction and away from functional component 6.

[0043] When the wire tends to move towards the side of the functional layer with functional component 6 due to tension or its own bending deformation (i.e., along the first direction C), the wall 101 can act as a physical stop structure, directly abutting the wire and restricting its further displacement towards the functional component 6, thereby preventing the wire from squeezing the functional component 6 on the circuit board and achieving wire alignment. Moreover, when the wire is aligned in the wire management space A, the wall 101 can withstand the weight of the wire or the restoring tension generated by the wire's own bending. Its load force can be effectively transferred to the snap-fit ​​component 2 through the wall 101, causing the snap-fit ​​component 2 to be more tightly embedded in the gap between the functional layers, enhancing friction and mechanical interference, and achieving a self-locking effect where the stronger the force, the more secure the locking.

[0044] When disassembly is required, apply external force (such as manual pressing or flicking) to the stop 1 along the second direction D to cause the snap-fit ​​2 to undergo elastic deformation or disengage from the interlayer gap, reducing the contact pressure or friction with the functional layer. This allows the snap-fit ​​2 to be pulled out of the gap, achieving a quick and non-destructive unlocking state without tools and with simple operation.

[0045] By setting the cable management space A on the side of the wall 101 away from the functional component 6 of the functional layer, not only can the cables be effectively organized, avoiding occupying the space on the side of the functional component 6 and preventing obstruction of heat dissipation of the components on the motherboard, but also the locking effect between the snap-fit ​​component 2 and the functional layer can be enhanced by a reasonable mechanical transmission mechanism, thereby improving reliable fixation.

[0046] In some embodiments, such as Figure 5 As shown, the wall 101 includes a first plate 102 and a second plate 103 formed by bending. The second plate 103 is arranged parallel to the functional layers when the snap-fit ​​2 is inserted between multiple functional layers. There is an angle between the first plate 102 and the second plate 103. The first plate 102 is used to resist the movement tendency of the wire along the first direction C, and the second plate 103 is used to support the wire.

[0047] The wall 101 can adopt a bent structure, including a connected first plate 102 and a second plate 103, which can be manufactured as a whole through processes such as stamping, bending or injection molding, and has good structural strength and elasticity.

[0048] When the connector 2 is inserted between adjacent functional layers (such as a motherboard tray or backplate), the second plate 103 is parallel to the functional layer (such as the motherboard surface) and is close to its orientation. The first plate 102 and the second plate 103 form a certain angle, such as 90° or an obtuse angle, so that the first plate 102 extends vertically or obliquely toward the side of the functional layer where the functional component 6 is provided.

[0049] The cable management space A is enclosed by the first plate 102, the second plate 103, and their connecting transition area. It can be an L-shaped or V-shaped groove structure, facilitating the entry of cables from one side of the first plate 102, their support by the second plate 103, and their exit from the other side, achieving an orderly and neat cable routing layout. The first plate 102 serves to prevent the cables from moving along the first direction C (i.e., towards the functional component 6), thus ensuring cable organization. The second plate 103, located below the first plate 102, supports the cable body or its curved sections, providing a flat and stable support surface to prevent sagging, swaying, or displacement due to gravity.

[0050] In practical use, such as Figure 11 As shown, due to its natural curvature and weight, the wire will exert a lateral force F on the wall 101. xAnd a vertically downward force F γ Vertical force F γ The second plate 103 is pressed firmly against the surface of the main plate, forming a fulcrum at the contact point. When the first plate 102 is simultaneously subjected to a lateral force F... x When in action, a rotational torque M will be generated around the fulcrum. x This causes the wall 101 to fit more tightly between the functional layers, increasing the friction and mechanical interference between the snap-fit ​​2 and the interlayer structure, thereby achieving a self-locking effect and improving the reliability of the fixation.

[0051] When disassembly is required, only a reverse operating force needs to be applied to the stop 1, generating a torque M in the opposite direction. x This allows the card connector 2 to detach from the interlayer gap, achieving quick and non-destructive unlocking without tools and with simple operation.

[0052] By setting up a bent wall 101 structure composed of a first plate 102 and a second plate 103, not only is reliable positioning and stable support for the wire achieved, but also a self-locking effect based on the fulcrum mechanism is formed by utilizing the force characteristics of the wire itself, which significantly enhances the fixation stability of the wire management structure.

[0053] In some embodiments, such as Figure 6 and Figure 7 As shown, the wall 101 is provided with a plurality of cable management grooves 104 at intervals along its height direction. Each cable management groove 104 is used to place at least one cable. The length direction of the cable management groove 104 is consistent with the length direction of the wall 101, and the depth direction of the cable management groove 104 is consistent with the first direction C.

[0054] The wall 101 is provided with multiple cable management channels 104 at intervals along its height direction, that is, in the direction perpendicular to the surface of the functional layer. Each cable management channel 104 can be used to accommodate one or more cables, realizing the layered and classified arrangement of multiple cables, which facilitates cable management.

[0055] The cross-section of the cable tray 104 can be U-shaped, V-shaped or semi-circular. Multiple cable trays 104 can be arranged in an array at intervals along the height of the wall 101, flexibly distributing different types of cables according to actual wiring needs, effectively avoiding crossover, tangling and mutual interference between cables.

[0056] The cable management channel 104 extends in the same direction as the length of the wall 101, from the first side to the second side. It can be in a straight line or an arc, facilitating the smooth passage of cables along a predetermined path and achieving neat cable routing. The opening of the cable management channel 104 faces away from the side of the functional layer containing the functional component 6, and its depth direction is consistent with the first direction C (i.e., the direction in which the cable tends to move towards the functional component 6). When the cable tends to move towards the functional layer due to tension or bending deformation, the sidewall of the cable management channel 104 can effectively block this displacement and prevent the cable from moving.

[0057] By installing multiple cable management channels 104 along the height of the wall 101, multiple cables can be independently accommodated and orderly separated without increasing lateral space occupation, thus improving the neatness and maintainability of the wiring. Whether the wall 101 is vertical or inclined on the functional layer, the cable management channels 104 provide stable support for the cables, preventing sagging, swaying, or displacement due to gravity. Simultaneously, they effectively transfer the entire weight of the cables to the wall 101 and further to the clips 2, enhancing the clamping force and friction between the clips and the upper and lower functional layers, thereby improving the overall locking reliability.

[0058] In some embodiments, the snap-fit ​​member 2 is a plate structure, with a first side of the plate structure connected to the wall 101, and a snap-fit ​​part 201 provided on the second side of the plate structure opposite to the first side; the snap-fit ​​part 201 can generate friction with at least one functional layer when the wall 101 is subjected to a load force along the first direction C, thereby achieving a locking state.

[0059] The snap-fit ​​component 2 is a plate structure that can be inserted into the gap between functional layers. It can be integrally formed from plastic or metal materials through processes such as injection molding and stamping. The first side of the plate structure is fixedly connected to the wall 101 or integrally formed to ensure that the load force can be effectively transferred from the stop component 1 to the snap-fit ​​component 2. The opposite second side is provided with a snap-fit ​​part 201.

[0060] The snap-fit ​​portion 201 can be a protrusion, a snap, a serrated structure, or an additional elastic flexible member, and is disposed at or near the free end of the second side of the plate structure. When the snap-fit ​​member 2 is inserted into the gap between adjacent functional layers, the snap-fit ​​portion 201 is tightly fitted with the surface of at least one functional layer (upper or lower layer) in the space, thereby achieving positioning and fixation.

[0061] When the stop 1 is not subjected to external force, or when subjected to a load force along the first direction C, the force is transmitted to the latching member 2 through the wall 101. This causes the plate structure to undergo slight elastic deformation or increases the contact pressure on the functional layer, making the latching part 201 tightly adhere to the surface of at least one functional layer (upper or lower layer). This generates sufficient friction or forms mechanical interference, achieving a stable locking state and effectively preventing the cable management structure from accidentally falling off. When disassembly is required, applying an external force to the stop 1 along the second direction D causes the latching member 2 to undergo or recover elastic deformation, reducing the contact pressure between the latching part 201 and the functional layer, eliminating frictional resistance, and thus allowing the latching member 2 to be easily pulled out of the gap, achieving a quick and non-destructive unlocking state.

[0062] By employing a plate-structured snap-fit ​​component 2, it can accommodate functional layer gaps of varying thicknesses. With a snap-fit ​​portion 201 at its free end, stable fixation can be achieved using friction or interference when subjected to a load in the first direction C, forming a self-reinforcing locking mechanism that tightens as it is pulled, thereby significantly improving fixation reliability.

[0063] In some embodiments, such as Figure 1 and Figure 3 As shown, the plate structure includes a third plate 202 and a fourth plate 203 formed by bending. The third plate 202 is connected to the second plate 103 and is disposed opposite to the first plate 102. The fourth plate 203 is disposed opposite to the second plate 103 and spaced apart to form a snap-fit ​​space B. At least one functional layer can extend into the snap-fit ​​space B. The fourth plate 203 has a snap-fit ​​part 201.

[0064] The plate structure of the snap-fit ​​component 2 is formed by bending to create a third plate 202 and a fourth plate 203, which together constitute a snap-fit ​​space B for accommodating the functional layer. The snap-fit ​​component 2 can be manufactured integrally through processes such as stamping, bending, or injection molding, and has good structural strength and elasticity. The third plate 202 is positioned opposite to the first plate 102 of the stop component 1, and the fourth plate 203 is positioned opposite to and spaced apart from the second plate 103 of the stop component 1. This allows the snap-fit ​​space B to be enclosed by the third plate 202, the fourth plate 203, and the second plate 103, forming a structure similar to a U-shaped groove, or an elastic snap-fit ​​structure such as a clamp or caliper.

[0065] During installation, the cable management structure can be inserted between adjacent functional layers. One of the functional layers, such as the motherboard, can extend into the snap-fit ​​space B and be clamped and fixed by the second plate 103 and the fourth plate 203. At the same time, the fourth plate 203 can be located between two functional layers. The fourth plate 203 has a snap-fit ​​part 201 at or near the free end of the snap-fit ​​member 2 to increase the friction between it and the functional layer or to form mechanical interference to prevent loosening and falling off.

[0066] The relative arrangement of the third plate 202 and the first plate 102 ensures that the cable management structure is subjected to balanced forces when snapped between functional layers, effectively preventing eccentric loading or tilting and improving the stability and reliability of the installation. The snap-fit ​​space B can accommodate and clamp the functional layers extending into it, achieving bidirectional fixation, thereby enhancing the strength and vibration resistance of the connection. Furthermore, due to the elastic characteristics of the plate structure, the snap-fit ​​space B can adapt to functional layers of different thicknesses, exhibiting good compatibility.

[0067] In some embodiments, such as Figures 3 to 5 As shown, the latching part 201 includes a plurality of latching hook structures that extend in the opposite direction to the latching space B; wherein, when the functional layer extends into the latching space B, the latching part 201 can latch with the functional layer located outside the latching space B.

[0068] The snap-fit ​​portion 201 includes multiple snap hook structures disposed on the fourth plate 203 and extending in the opposite direction to the snap-fit ​​space B, that is, protruding toward the side away from the interior of the snap-fit ​​space B. Each snap hook structure may be inverted, hook-shaped, or other shapes suitable for snap-fit.

[0069] During installation, due to the stacked arrangement of two functional layers, one functional layer is inserted into the locking space B from the outside. As the functional layer gradually enters, the surface of the other functional layer can contact the inclined surface at the front end of the hook structure, allowing it to slide smoothly. After one functional layer is inserted into the locking space B, the hook of the hook structure can engage with a pre-set opening, slot, or edge step on the other functional layer located outside the locking space B, thereby forming a mechanical limit and achieving reliable locking.

[0070] The hook structure, located on the outside of the locking space B, forms a strong mechanical engagement with the functional layer, effectively preventing the cable management structure from warping, loosening, or falling off due to vibration, impact, or cable tension during equipment operation. Multiple hook structures are spaced apart along the length of the fourth plate 203, creating multi-point constraints that evenly distribute force, further enhancing the stability of the cable management structure under high-frequency vibration environments.

[0071] In some embodiments, the latching portion 201 may be made of a flexible material with elasticity and a high coefficient of friction, such as elastic foam (e.g., EVA foam, silicone foam, etc.) or anti-slip strips (e.g., rubber strips, silicone strips, etc.). The elastic material can be glued to the end of the fourth plate 203 and the side facing away from the latching space B. When the fourth plate 203 is inserted into the gap between the functional layers, the latching portion 201 comes into contact with at least one surface of the functional layer. Due to the elastic compressibility and friction of the material itself, a pre-tightening force can be formed by compression deformation without the need for mechanical latches, and a stable frictional connection can be established between the material and the surface of the functional layer, thereby achieving reliable locking.

[0072] In some embodiments, such as Figures 3 to 5 As shown, the cable management structure also includes: multiple compensation parts 3, which are arranged along the depth direction of the snap-fit ​​space B. The multiple compensation parts 3 are arranged on the side of the second plate 103 facing the snap-fit ​​space B, and / or on the side of the fourth plate 203 facing the snap-fit ​​space B; the end of the compensation part 3 facing away from the third plate 202 is provided with an arc surface or a slope.

[0073] The cable management structure also includes multiple compensation parts 3, which are arranged along the depth direction of the locking space B and distributed on the side of the second plate 103 facing the locking space B, and / or on the side of the fourth plate 203 facing the locking space B. The compensation parts 3 can be protrusions, rib-like structures, or elastic support points, and are spaced apart along the length direction of the fourth plate 203 or the second plate 103. The free end of each compensation part 3, i.e., the end facing away from the third plate 202, has an arc surface or a slope, forming a smoothly transitioning guide contour.

[0074] During installation, when the functional layer is inserted into the snap-fit ​​space B, its surface first contacts the arc or beveled surface at the end of the compensation part 3. This structure effectively reduces insertion resistance, prevents jamming or scratching of the functional layer surface, and ensures smooth and undamaged insertion. After the functional layer is fully inserted, the compensation part 3 maintains contact with its surface and can undergo slight deformation according to the actual thickness of the functional layer to automatically fill dimensional deviations and eliminate loose gaps. Especially when dealing with functional layers of different batches, thicknesses, or assembly tolerances, the compensation part 3 can adjust the contact pressure to ensure a stable and uniform clamping force.

[0075] By incorporating multiple compensation units 3, the adaptability to functional layers of different sizes is enhanced, improving the compatibility and reliability of the snap-fit ​​connection. It also significantly improves the smoothness of installation, the stability of the connection, and the resistance to loosening under vibration.

[0076] In some embodiments, such as Figure 3 As shown, the stop 1 and the snap-fit ​​2 are an integrated structure, and the stop 1 is provided with the avoidance structure 4 of the avoidance function layer upper functional component 6.

[0077] The stop component 1 and the snap-fit ​​component 2 are an integrated structure, which can be manufactured as a whole through injection molding, stamping, or bending forming processes to form a complete wiring structure. The integrated structure not only improves the overall integrity and mechanical strength of the structure, but also simplifies the assembly process and reduces the number of parts and production costs.

[0078] The stop member 1 is equipped with a clearance structure 4, which is used to allow the cable management structure to avoid the functional components 6 on the functional layer during installation. The clearance structure 4 can be a groove, notch, through hole, or locally thinned area, and its shape and position are adapted to the layout of the functional components 6 on the functional layer. By setting the clearance structure 4, the functional components 6 on the functional layer can be effectively avoided, preventing damage to the functional components 6 and interface deformation caused by structural interference during installation.

[0079] In some embodiments, such as Figure 1 As shown, multiple reinforcing ribs 5 can be provided on one side of the cable management space A of the stop member 1. The reinforcing ribs 5 can be arranged longitudinally, laterally, or in a grid pattern, and their cross-sections can be triangular, trapezoidal, or semi-circular. They are integrally formed with the wall 101 of the stop member 1 to form a reinforced structure. The reinforcing ribs 5 are used to withstand the tensile force, bending moment, and other loads applied by the cable, thereby effectively improving the bending stiffness and local strength of the wall 101 and preventing the thin-walled structure from deflecting, deforming, or breaking. The number, height, and thickness of the reinforcing ribs 5 can be adjusted according to the actual stress conditions to meet the structural strength requirements of different application scenarios.

[0080] Example 2

[0081] This application also provides an electronic device, such as... Figures 8 to 11 As shown, it includes: a first functional layer 10, on which multiple wires are connected; a second functional layer 20, on which the first functional layer 10 is installed at intervals, and a slot 2001 is provided on the side of the second functional layer 20 facing the first functional layer 10; the cable management structure 30 includes: a stop member 1, which has a cable management space A for restricting the movement of the wires; a snap-fit ​​member 2, which is connected to the stop member 1 and is used to insert between the first functional layer 10 and the second functional layer 20; when the stop member 1 is subjected to a load force of the wires along the first direction C, the snap-fit ​​member 2 snaps into the slot 2001, thereby achieving a locked state; when the stop member 1 is subjected to a load force along the second direction D, the snap-fit ​​member 2 disengages from the slot 2001, thereby achieving an unlocked state.

[0082] The electronic device includes a first functional layer 10 and a second functional layer 20, as well as a cable management structure 30 disposed between the two. The first functional layer 10 may be a motherboard that carries circuits or implements cable connection functions, and multiple cables, such as power cables, data cables, and signal cables, are connected to it. The second functional layer 20 is installed below the first functional layer 10 at intervals, and may be, for example, a bracket, cover plate, tray, or other structural component. The second functional layer 20 has a slot 2001 on the side facing the first functional layer 10. The slot 2001 may be a groove, a through hole, or a partially open structure, used to cooperate with the snap-fit ​​member 2 in the cable management structure 30 to achieve positioning and locking.

[0083] The cable management structure 30 includes a stop 1 and a snap-fit ​​2. The stop 1 has a cable management space A for accommodating and restricting cable movement, which can orderly store and limit the movement of multiple cables. The snap-fit ​​2 is connected to the stop 1 and is used to insert into the gap between the first functional layer 10 and the second functional layer 20.

[0084] In the installed state, the snap-fit ​​component 2 of the cable management structure 30 is inserted into the interlayer gap and engages with the slot 2001 on the second functional layer 20. When the stop component 1 is subjected to a load force from the cable along the first direction C, the load force is transmitted through the stop component 1 to the snap-fit ​​component 2, making it more tightly embedded in the slot 2001, forming a mechanical engagement or increasing friction, thereby entering a locked state and effectively preventing the cable management structure 30 from loosening or falling off. When disassembly or maintenance is required, an external force along the second direction D (i.e., opposite to the first direction C) is applied to the stop component 1, causing the snap-fit ​​component 2 to undergo elastic deformation and disengage from the slot 2001 constraint, allowing the entire cable management structure 30 to be pulled out of the gap, achieving a quick and non-destructive unlocking state.

[0085] The electronic device provided in this embodiment can be a server chassis, storage device chassis, industrial control cabinet, etc. The cable management structure 30 utilizes the gaps between existing functional layers within the electronic device for installation, eliminating the need for additional studs or holes in the circuit board. This not only replaces traditional adhesive bonding or screw fastening methods, solving problems such as adhesive aging and failure under high-temperature environments, residual adhesive contamination, and damage to the circuit board from screw drilling, but also allows for manual installation and disassembly, simplifying operation and significantly reducing assembly and maintenance time. The cable management space A can classify, organize, and reliably limit multiple cables, significantly improving wiring neatness and preventing cable displacement, cross-entanglement, or compression of functional components 6, ensuring electrical safety and system reliability. Simultaneously, the cable management structure 30 can be installed on the side of the server chassis, making its structure compact and space-saving. The cable management structure 30 provides almost no obstruction to the main airflow duct inside the chassis, allowing for smooth airflow and minimal impact on the overall heat dissipation performance of the electronic device, thus improving its heat dissipation efficiency and operational stability.
