Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to an optoelectronic integrated wiring box. Background Technology

[0002] With the rapid development of fiber optic communication technology, optoelectronic integrated distribution boxes, as key wiring devices in communication networks, are widely used in base stations, equipment rooms, and outdoor access points to achieve the connection, distribution, and scheduling between optical cables and between optical cables and optical communication equipment. Distribution boxes typically contain multiple cable mounting racks for the orderly fixing and management of large numbers of cables, ensuring the stability and reliability of communication lines.

[0003] Traditional optoelectronic integrated wiring boxes have the following shortcomings in practical use:

[0004] First, there's the issue of cable bending damage. Existing distribution boxes often use fixed cable trays or hook structures to limit and secure cables. After the cable is introduced through the cable entry point, it needs to be bent at a certain angle to be inserted into the cable tray. Stress concentration easily occurs at the bend, which can damage the internal optical fibers of the cable over time, affecting signal transmission quality. Especially at the cable exit point, the cable usually needs to be bent at a large angle, easily exceeding its allowable bending radius, causing a decrease in transmission performance or even line interruption.

[0005] Secondly, there is the issue of U-shaped bracket deformation under stress. Most existing cable mounting racks use a U-shaped structure. After the cables are fixed, the weight and tension continuously exert a downward vertical pulling force on the U-shaped bracket, causing it to deform or even break after prolonged stress, affecting the stability and reliability of the cable installation. Simultaneously, when the cables are subjected to external tension, this force is directly transmitted to the U-shaped bracket, easily causing loosening of the connection between the U-shaped bracket and the distribution box.

[0006] Third, there is the problem of insufficient heat dissipation. The cables inside the wiring box are densely packed and run close to the bottom wall of the U-shaped frame, which causes heat to accumulate and is difficult to dissipate. Long-term operation of the cables in a high-temperature environment will accelerate aging, shorten their service life, and also pose certain safety hazards. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an integrated optoelectronic wiring box.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] An integrated optoelectronic wiring box, comprising:

[0010] A wiring box, which has a cable rack installed inside for cable management;

[0011] The cable mounting bracket includes: a U-shaped bracket, detachably fixed to the inner wall of the wiring box, with a cable pass-through opening in the middle of its bottom end along its length; multiple cable trays, spaced apart on both sides of the U-shaped bracket, for cable separation and clamping; a dust cover, detachably connected to the open end of the U-shaped bracket; an elastic ball, clamped in the cable tray, with the clamping point extending outside the cable tray; and a slot, formed on the elastic ball and located at the clamping position between the elastic ball and the cable tray.

[0012] The elastic ball is located on both sides of the slot and abuts against the inner and outer walls of the U-shaped frame. The part of the elastic ball inside the slot forms a buffer support structure for the cable, the part of the elastic ball outside the slot forms an arc-shaped guiding structure for the cable, and the part of the elastic ball inside the slot supports the cable from the cable insertion port to the slot and forms a heat dissipation gap between the cable and the bottom wall of the U-shaped frame.

[0013] Preferably, the surface of the elastic ball has an arc-shaped channel along its circumference, the arc-shaped channel intersects with the groove, and the arc-shaped channel is located in at least half of the circumference of the elastic ball.

[0014] Preferably, the ends of the arc-shaped channel on both the outer and inner sides of the U-shaped frame are configured as fan-shaped flared portions.

[0015] Preferably, the bottom end of the groove is arc-shaped, and the groove of the elastic ball at the bottom end of the groove is arc-shaped to match it.

[0016] Preferably, both free ends of the top of the U-shaped frame are provided with V-shaped slides, and both ends of the dust cover are provided with V-shaped sliders that are slidably connected to the V-shaped slides.

[0017] Preferably, the edge of the threading opening is provided with a rounded transition portion, and the inner wall of the threading opening is attached with a wear-resistant rubber sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The protruding part located inside the inner wall of the U-shaped frame after the elastic ball is inserted into the cable groove provides continuous and elastic support for the suspended cable section from the cable insertion port to the cable groove. This ensures that the cable section will not directly stick to the bottom wall of the U-shaped frame under its own weight. Instead, a continuous air insulation layer, i.e. a heat dissipation gap, is formed between the cable and the bottom wall, thus ensuring sufficient air convection space and facilitating heat dissipation during cable operation.

[0020] 2. The spherical parts on both sides of the slot protrude from the inner and outer surfaces of the U-shaped frame sidewall. On the one hand, the elastic deformation of the elastic ball absorbs external vibration and impact kinetic energy, playing a buffering and protective role. On the other hand, when the cable is subjected to tensile force, the arc-shaped mating surface between the elastic ball and the slot can convert the vertical tension into a horizontal component force and distribute it to the upper and lower ends of the sidewall, reducing the risk of vertical tensile deformation of the U-shaped frame and improving the impact resistance and stress stability of the overall structure.

[0021] 3. By using the protruding part of the elastic ball outside the outer wall of the U-shaped frame and the guiding effect of the arc-shaped channel on the cable, when the cable passes through this position to connect to the equipment, its surface is in close contact with the arc-shaped outer wall of the elastic ball, and the lead-out path is forcibly guided into an arc-shaped trajectory, thereby reducing the damage to the internal optical fiber of the cable caused by sharp bends and ensuring communication quality.

[0033] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0034] Example

[0035] like Figure 1-9As shown, an integrated optoelectronic wiring box includes a wiring box 1 and a cable mounting rack 2 installed inside the wiring box 1. The wiring box 1 is preferably made of stainless steel or aluminum alloy plate through bending and welding, and has an overall rectangular box structure, with an internal cavity for accommodating cables and various communication modules. One side of the wiring box 1 has an openable door (not shown in the figure) for easy daily construction and maintenance. The cable mounting rack 2, as the core cable management unit, is detachably installed on the rear or side wall of the wiring box 1 using bolt assemblies or snap-fit ​​structures. The cable mounting rack 2 includes a U-shaped frame 21, a cable tray 22, a dust cover 23, an elastic ball 24, and a slot 25. The U-shaped frame 21 is made of cold-rolled steel plate with a thickness of 1.5mm to 2.5mm, formed by continuous stamping. Its cross-section is U-shaped, with two parallel and vertically extending side walls and a horizontal bottom wall connecting the bottom ends of the two side walls. The U-shaped frame 21 extends horizontally along the width direction of the wiring box 1, and its overall length can be set from 300mm to 800mm depending on the internal space of the wiring box 1. The distance between the two side walls of the U-shaped frame 21 (i.e., the groove width) is set from 50mm to 150mm to provide sufficient space for cable management. A cable entry port 29 is provided along the length of the bottom wall of the U-shaped frame 21, allowing cables to pass through from the outside into the interior of the U-shaped frame 21. This cable entry port 29 is a long rectangular opening, and its width must be greater than the outer diameter of a single cable, preferably set to 30mm to 60mm. Multiple cable grooves 22 located on the two side walls of the U-shaped frame 21 are spaced apart using laser cutting or stamping processes. Specifically, the wire grooves 22 on the two side walls correspond one-to-one in the horizontal position, forming a set of cable clamping stations. The center distance between adjacent wire grooves 22 is set to 20mm to 50mm according to the cable diameter. Each wire groove 22 is an open groove structure that extends vertically downward from the top of the side wall to a certain height from the bottom wall, and its bottom end is preferably stamped into an arc-shaped transition surface.

[0036] Furthermore, to achieve secure cable connection and multi-dimensional force guidance, please refer to [link / reference needed]. Figures 3 to 6As shown, an elastic ball 24 made of elastic material is snapped into each groove 22. The elastic ball 24 is preferably integrally molded from ethylene propylene diene monomer (EPDM) rubber or silicone rubber with a Shore hardness of A30 to A70, exhibiting excellent aging resistance and elastic recovery. The diameter of the elastic ball 24 must be larger than the opening width of the groove 22 to ensure it can be securely snapped into the groove 22. A recessed groove 25 is formed around the central area of ​​the outer circumference of the elastic ball 24. This groove 25 is a recessed groove at the point where the elastic ball 24 engages with the U-shaped frame 21, and its axial width is adapted to the thickness of the plate material of the side wall of the U-shaped frame 21 (typically 1.5mm to 3.0mm). The elastic ball 24 is snapped into the edge of the groove 22 through the groove 25, and the spherical portions on both sides of the groove 25 pass through the groove 22 and protrude from the inner and outer wall surfaces of the side wall of the U-shaped frame 21, respectively. The bottom shape of the slot 25 matches the arc-shaped transition surface at the bottom of the cable tray 22, forming a surface contact fit to increase the contact area and improve the snap-fit ​​stability. When the elastic ball 24 is inserted into the cable tray 22, the spherical areas on both sides of the slot 25 elastically abut against the inner and outer surfaces of the sidewall of the U-shaped frame 21, respectively, thus axially limiting the elastic ball 24 and preventing it from coming out of the cable tray 22 under external force. At this time, the portion of the elastic ball 24 located inside the opening of the cable tray 22 naturally forms a buffer support structure for the cable. When the cable is subjected to external vibration or impact, this structure can absorb some kinetic energy through elastic deformation, providing buffer protection. The protruding portion of the elastic ball 24 outside the outer wall of the U-shaped frame 21 forms an arc-shaped guiding structure for the cable. When the cable passes through this position to connect to the equipment, the cable surface is tightly against the arc-shaped outer wall of the elastic ball 24, forcibly guiding the cable's exit path into an arc trajectory, effectively avoiding damage to the internal optical fiber of the cable caused by sharp bends. Meanwhile, the protruding portion of the elastic ball 24 located inside the inner wall of the U-shaped frame 21 provides elastic support for the suspended cable segment between the cable entry port 29 and the cable tray 22. This prevents the cable segment from directly contacting the bottom wall of the U-shaped frame 21 under its own weight, instead forming a continuous air insulation layer, i.e., a heat dissipation gap, between the cable and the bottom wall. The height of this heat dissipation gap is determined by the protrusion size of the elastic ball 24, preferably 5mm to 15mm, to ensure sufficient air convection space.

[0037] Furthermore, to precisely limit the cable within the cable tray 22 and prevent unnecessary movement or slippage along the length of the U-shaped bracket 21, please refer to [link to relevant documentation]. Figure 5 and Figure 7As shown, an arc-shaped channel 26 is also formed on the outer surface of the elastic ball 24. This arc-shaped channel 26 is an inwardly recessed arc-shaped groove formed on the surface of the elastic ball 24, extending circumferentially along the elastic ball 24. During its extension, the arc-shaped channel 26 intersects with the wire groove 22, thereby crossing the wire groove 22 and connecting the two parts of the elastic ball 24 located inside and outside the U-shaped frame 21. Specifically, the angle occupied by the arc-shaped channel 26 in the circumferential direction of the elastic ball 24 is not less than 180°, preferably 270° to 300°, thus providing a sufficiently long wrapping and guiding path for the cable. The cross-section of the arc-shaped channel 26 is arc-shaped or U-shaped, and its radius of curvature needs to be adapted to the radius of the cable to be clamped, typically set to 0.55 to 0.65 times the outer diameter of the cable, so that the cable can fit snugly against the inner wall of the arc-shaped channel 26 after being clamped in. When the cable is passed through the cable entry port 29 and pulled downwards into the cable groove 22, the cable will preferentially fall into the arc-shaped channel 26. The two side walls of the arc-shaped channel 26 form a circumferential wrapping and lateral restraint on the cable, effectively restricting the cable's freedom in the horizontal direction and ensuring its stable arrangement after fixing. On the other hand, due to the restraining effect of the arc-shaped channel 26, the cable routing on both the inner and outer sides of the U-shaped frame 21 is controlled within the central area of ​​the elastic ball 24, significantly reducing the direct contact friction between the cable surface and the side wall edge of the U-shaped frame 21 and the port of the cable groove 22, thus avoiding wear on the cable sheath caused by long-term friction.

[0038] Furthermore, to prevent localized stress concentration or scratch damage caused by abrupt angle changes at the cable's entry and exit points of the arc-shaped channel 26, fan-shaped flares are provided at both the ends of the arc-shaped channel 26 located outside the outer wall of the U-shaped frame 21 and inside the inner wall of the U-shaped frame 21. These fan-shaped flares are formed directly during the molding process of the elastic ball 24, and their shape resembles a flared mouth that gradually widens along the extension direction of the arc-shaped channel 26. Specifically, the width of the fan-shaped flare increases linearly or arc-shaped from the main body of the arc-shaped channel 26 towards the end, with the increasing angle preferably between 15° and 30°. This flare structure allows for a smooth transition in the bending radius of the cable when entering or leaving the arc-shaped channel 26, effectively preventing the cable from undergoing hard bending or shearing forces at the channel ends, further ensuring that the transmission performance of the cable, especially the internal optical fiber, remains unaffected.

[0039] Furthermore, to facilitate production and assembly and further improve the connection strength between the elastic ball 24 and the U-shaped frame 21, the bottom end of the cable groove 22 is machined into a concave arc-shaped structure. Correspondingly, the groove 25 on the elastic ball 24 is also set as an arc-shaped structure with the same radius of curvature at the corresponding position of the bottom end of the cable groove 22. That is, the arc shape at the bottom end of the cable groove 22 and the arc shape at the bottom of the groove 25 form a nested fit. When the elastic ball 24 is subjected to the downward pull of the cable, the arc-shaped mating surface can convert part of the vertical pull into a horizontal component, thereby reducing the direct vertical force on the side wall of the U-shaped frame 21. At the same time, compared with the right-angle mating structure, the arc-shaped mating structure has a larger contact area, which can effectively reduce the pressure per unit area and prevent the side wall of the U-shaped frame 21 from undergoing plastic deformation or material fatigue due to long-term local stress.

[0040] For further details, please refer to Figure 8 As shown, to achieve dust protection for the cables inside the U-shaped frame 21 and facilitate quick assembly and disassembly by construction personnel, a dust cover 23 is detachably installed at the open end of the U-shaped frame 21. Specifically, V-shaped slides 27 are provided along the length of each of the free edges at the top of the two side walls of the U-shaped frame 21. The V-shaped slide 27 is a groove with a V-shaped cross-section, and its V-angle is preferably 60° to 90°. Correspondingly, V-shaped sliders 28 are integrally formed at the lower edges of the left and right sides of the dust cover 23. The V-shaped sliders 28 are concave with a V-shaped cross-section, and their V-angle is the same as that of the V-shaped slides 27. The dust cover 23 can be pushed in or slid out from one end along the length of the U-shaped frame 21 through the sliding engagement of the V-shaped sliders 28 and the V-shaped slides 27, or it can be inserted by pressing the two side walls of the U-shaped frame 21. During installation, simply align the V-shaped slider 28 of the dust cover 23 with the end opening of the V-shaped slide 27 and push it forward for quick installation; to remove, simply pull it out in the opposite direction. This dovetail (V-shaped) sliding guide structure not only has a self-aligning function, ensuring accurate alignment between the dust cover 23 and the opening of the U-shaped frame 21, but its wedge-shaped mating surface also generates a self-locking friction force when the dust cover 23 is subjected to the tension of the two side walls of the U-shaped frame 21, preventing the dust cover 23 from accidentally loosening due to vibration. Furthermore, it can be operated manually without the aid of any screwdrivers or other tools, greatly improving the efficiency of on-site construction and maintenance.

[0041] Furthermore, to protect the cable sheath from damage when passing through the bottom wall of the U-shaped bracket 21, the edges of the cable entry port 29 are rounded to form a rounded transition section, with a radius of curvature preferably between 2mm and 5mm. Simultaneously, a wear-resistant rubber sheath is attached to the inner wall of the cable entry port 29 via vulcanization bonding or snap-fitting. This wear-resistant rubber sheath is preferably made of polyurethane rubber with excellent wear resistance, has a thickness of 1mm to 3mm, and a smooth inner surface. This wear-resistant rubber sheath completely covers the sharp metal edges of the cable entry port 29, ensuring that the cable only contacts the soft rubber surface during cable insertion, effectively preventing scratches or wear on the cable sheath and significantly improving the safety of the cable entry process.

[0042] The following description, in conjunction with the specific structure of this utility model, explains the cable installation and stress application process.

[0043] Specifically, during construction and installation, the externally introduced cable is first inserted into the internal cavity of the U-shaped frame 21 through the cable entry port 29. At this time, the cable sheath is effectively protected by the wear-resistant rubber sleeve on the inner wall of the cable entry port 29. After entering the U-shaped frame 21, the cable passes sequentially through the protruding part of the elastic ball 24 located inside the U-shaped frame 21 according to the pre-planned cable routing path. During this process, the inner protruding part applies an upward elastic support force to the cable, preventing the cable from directly contacting the bottom wall of the U-shaped frame 21 on this section of the path, thus ensuring the existence of a heat dissipation gap. When the cable continues to be inserted into the cable tray 22, the cable first enters the arc-shaped channel 26 on the surface of the elastic ball 24. The inner wall of the arc-shaped channel 26 wraps around and guides the cable, ensuring that the cable is accurately positioned in the center of the cable tray 22. When the cable is subjected to unforeseen external pulling force, this force is first transmitted to the elastic ball 24, which is in close contact with the cable. Since the elastic ball 24 is engaged with the wire groove 22 via the slot 25, and the two sides of the slot 25 abut against the inner and outer walls of the U-shaped frame 21 respectively, the force exerted by the cable on the elastic ball 24 is decomposed into a compressive force perpendicular to the surface of the elastic ball 24 and a force parallel to the side wall of the U-shaped frame 21 (the vertical component of this force is tensile force). The compressive force is absorbed by the elastic deformation of the elastic ball 24 and evenly transmitted to the side wall of the U-shaped frame 21, while the vertical tensile force is transmitted to the entire side wall of the U-shaped frame 21 through the arc-shaped mating surface between the elastic ball 24 and the wire groove 22 and the side wall of the slot 25. Compared to the concentrated downward force exerted by the cable directly on the bottom wall of the U-shaped frame 21 in traditional structures, the tensile force in this invention is distributed to the upper and lower ends of the side wall, greatly reducing the risk of vertical tensile deformation of the U-shaped frame 21. Finally, when the cable is led out from inside the U-shaped frame 21 to connect to external equipment, the cable bypasses the protruding portion of the elastic ball 24 located on the outside of the U-shaped frame 21. Because this part has a smooth arc-shaped surface, and the fan-shaped flare of the arc-shaped channel 26 provides a gentle transition path, the cable lead-out path is naturally arc-shaped, and its bending radius is controlled within a safe range, thereby ensuring that the cable, especially the optical fiber inside, will not suffer additional loss or breakage due to excessive bending, thus guaranteeing communication quality.

[0044] The cable entry port 29, which runs the length of the bottom wall of the U-shaped frame 21, along with the wear-resistant rubber sheath and rounded edges on the inner wall of the cable entry port 29, provides a dedicated channel for cables to pass through from the outside into the U-shaped frame 21. At the same time, it completely wraps around the metal edges, so that the cable only comes into contact with the soft and smooth rubber surface during the cable insertion process. This effectively avoids scratches or wear on the outer sheath of the cable, and significantly improves the safety and reliability of the cable entry process.

[0045] The protruding part located inside the inner wall of the U-shaped frame 21 after the elastic ball 24 is inserted into the cable groove 22 provides continuous and elastic support for the suspended cable section from the cable opening 29 to the cable groove 22. This ensures that the cable section will not directly stick to the bottom wall of the U-shaped frame 21 under its own weight, but forms a continuous air insulation layer, i.e., a heat dissipation gap, between the cable and the bottom wall, thereby ensuring sufficient air convection space and facilitating heat dissipation during cable operation.

[0046] By inserting elastic balls 24 with a diameter larger than the opening width of each cable tray 22 into each cable tray 22, and using the concave grooves 25 on the outer circumference of the elastic balls 24 to form a snap-fit ​​with the edge of the cable tray 22, and the spherical parts on both sides of the grooves 25 protruding from the inner and outer surfaces of the side wall of the U-shaped frame 21 respectively, on the one hand, the elastic deformation of the elastic balls 24 absorbs external vibration and impact kinetic energy, playing a buffering and protective role; on the other hand, when the cable is subjected to tensile force, the arc-shaped mating surface between the elastic balls 24 and the cable tray 22 can convert the vertical tensile force into a horizontal component force and distribute it to the upper and lower ends of the side wall, which greatly reduces the risk of vertical tensile deformation of the U-shaped frame 21 and significantly improves the impact resistance and stress stability of the overall structure.

[0047] By creating an arc-shaped channel 26 on the surface of the elastic ball 24 that intersects with the wire groove 22 and extends circumferentially, the angle of the arc-shaped channel 26 is not less than 180° and the radius of curvature of the cross section is adapted to the outer diameter of the cable. When the cable is inserted into the wire groove 22, it will preferentially fall into the arc-shaped channel 26. Its two side walls form a circumferential wrapping and lateral restraint on the cable, effectively constraining the cable's freedom in the horizontal direction, so that it remains stably arranged after being fixed. At the same time, it significantly reduces the direct contact friction between the cable surface and the side wall edge of the U-shaped frame 21 and the port of the wire groove 22, avoiding wear of the cable sheath caused by long-term friction.

[0048] By utilizing the protruding portion of the elastic ball 24 located outside the outer wall of the U-shaped frame 21, and the guiding effect of the arc-shaped channel 26 on the cable, when the cable passes through this position to connect to the device, its surface is tightly attached to the arc-shaped outer wall of the elastic ball 24, and the lead-out path is forcibly guided into an arc-shaped trajectory, thereby effectively avoiding damage to the internal optical fiber of the cable caused by sharp bends and ensuring communication quality.

[0049] By providing fan-shaped flares at both ends of the arc-shaped channel 26, outside the inner and outer walls of the U-shaped frame 21, with the width of the flares gradually increasing from the main body of the arc-shaped channel 26 towards the end, the bending radius of the cable can be smoothly transitioned when entering or leaving the arc-shaped channel 26. This effectively avoids the cable from being rigidly bent or subjected to shearing force at the channel port, further ensuring that the transmission performance of the cable, especially the internal optical fiber, is not affected.

[0050] By processing the bottom end of the groove 22 into a concave arc-shaped structure, and setting an arc-shaped structure with the same radius of curvature at the corresponding position of the slot 25 of the elastic ball 24, the two form a tight nested fit. Compared with the right-angle fit structure, the arc-shaped mating surface has a larger contact area, which can effectively reduce the pressure per unit area, prevent the side wall of the U-shaped frame 21 from plastic deformation or material fatigue due to long-term local stress, and at the same time enhance the firmness of the snap-fit.

[0051] By setting V-shaped slides 27 at the top of the two side walls of the U-shaped frame 21 and matching V-shaped sliders 28 on the side of the dust cover 23, the dust cover 23 can be quickly disassembled and assembled by hand through sliding engagement without the need for tools; at the same time, the V-shaped wedge mating surface generates self-locking friction when under tension, preventing the dust cover 23 from accidentally loosening due to vibration, thus combining convenient construction and maintenance efficiency with reliable dustproof and anti-loosening performance.

[0052] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
