TECHNICAL FIELD

[0001] The present application relates to the technical field of weak current box, in particular to a smart weak current box structure supporting modular expansion and a wiring architecture thereof. BACKGROUND

[0002] At present, smart weak current boxes are gradually becoming the core hub of home and office networks, and they need to integrate multiple devices such as optical modems, routers, and switches.

[0003] The wiring structure of traditional weak current boxes is still relatively primitive, and fixed wire management rings or simple wire binding posts are often used. In the face of complex scenarios where device port layouts are different and cable types are diverse, the existing structure cannot provide intelligent and accurate cable guidance and management, resulting in chaotic cables in the box, which seriously hinders the performance improvement and user experience of smart weak current boxes.

[0004] Therefore, we propose a smart weak current box structure supporting modular expansion and a wiring architecture thereof to solve the above problems. SUMMARY

[0005] (I) Technical problems solved In view of the deficiencies of the prior art, the present application provides a smart weak current box structure supporting modular expansion and a wiring architecture thereof, which solves the problems of rigid and single function of the wiring structure of the existing weak current box, and the problems of internal cable cross-winding, mutual interference, and difficult maintenance.

[0006] (II) Technical solutions In order to achieve the above purpose, the present application specifically adopts the following technical solutions: A smart weak current box structure supporting modular expansion and a wiring architecture thereof, comprising: a wire rack support plate; a plurality of arc-shaped wire support hoops, one end of each arc-shaped wire support hoop is connected to the wire rack support plate through a hinge shaft and can rotate independently around the hinge shaft; The outer edge of the arc-shaped wire support hoop is provided with a wire groove for guiding and supporting the cable; The arc-shaped wire support hoop has at least two working states: In the first working state, the arc-shaped wire support hoop assumes an upper arch and lower concave posture, and is adjusted to different angles by rotating around the hinge shaft to adjust the guiding height of the wire groove; In the second working state, the arc-shaped wire support hoop is flipped around the hinge shaft from the first working state and assumes a lower arch and upper concave posture, and the arc top structure is turned downward, and the upper concave part forms a first horizontal channel for supporting the cable from the upper part.

[0010] Further, in the first working state, while the arc-shaped wire supporting bracket is rotated to adjust the guide height of the wire slot, the leading direction of the cable guided by the wire slot is changed accordingly, thereby causing the longitudinal landing point of the cable extending downward after being disengaged from the guide to continuously shift laterally; The distance between two adjacent arc-shaped wire supporting brackets is less than the width of the wire slot, and the arc-shaped wire supporting brackets are arranged in groups of three, wherein the arc-shaped wire supporting bracket in the middle is configured to be flipped to the second working state to receive the cables guided from the arc-shaped wire supporting brackets on the two sides of the same group.

[0011] Further, an angle positioning mechanism is further included for locking the arc-shaped wire supporting bracket at a preset angle; The angle positioning mechanism includes a plurality of limiting grooves opened in the circumferential direction of the hinge shaft and a waist-shaped hole arranged at one end of the arc-shaped wire supporting bracket, and the waist-shaped hole is movably sleeved with the hinge shaft; One end of the inner wall of the waist-shaped hole is provided with a spring piece, and the other end of the inner wall is provided with a limiting pin matched with the limiting groove; The spring piece continuously abuts against the hinge shaft with its elastic force, drives the waist-shaped hole of the arc-shaped wire supporting bracket to displace, and enables the limiting pin to be stably clamped into the limiting groove of the hinge shaft.

[0012] Further, the axial direction of the limiting pin is parallel to the length direction of the waist-shaped hole, and the position of the limiting pin is arranged in the middle relative to the waist-shaped hole, and the inner width of the limiting groove is greater than the diameter of the limiting pin, so that the limiting pin only contacts the edge of the slot of the limiting groove.

[0013] Further, one end of the limiting pin arranged on the inner wall of the waist-shaped hole is also symmetrically provided with two auxiliary pins, which are respectively located on the two sides of the limiting pin and whose axial direction is parallel to the length direction of the waist-shaped hole; when the limiting pin is clamped into the limiting slot, the two auxiliary pins are also inserted into the corresponding limiting slot inside the hinge shaft.

[0014] Further, the inner wall of the wire slot of the arc-shaped wire supporting clamp is provided with a plurality of rubber blocks on both sides, which are used for elastically clamping the cable in the wire slot; the outer side of the arc-shaped wire supporting clamp is provided with an operation mark, which is used for indicating the axial direction of the limiting pin, so as to guide the user to apply force in this direction to realize angle unlocking; one end of the elastic sheet close to the hinge shaft is arc-shaped, and the both ends of the wire rack supporting plate are also provided with connecting ear plates.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0019] EMBODIMENT As Figures 1-14 shown, one embodiment of the present application proposes a wiring rack structure, which comprises a wire rack support plate 1; A plurality of arc-shaped wire support clamps 2, one end of each of the arc-shaped wire support clamps 2 is connected with the wire rack support plate 1 through a hinged shaft 11 and can independently rotate around the hinged shaft 11; The outer edge of the arc-shaped wire support clamp 2 is provided with a wire groove 21 for guiding and supporting the cable; The arc-shaped wire support clamp 2 has at least two working states: In the first working state, the arc-shaped wire support clamp 2 assumes an upper-arch lower-concave posture, and is rotated around the hinged shaft 11 to different angles to adjust the guiding height of the wire groove 21 thereof; In the second working state, the arc-shaped cable support 2 is flipped by 180 degrees around the hinge axis 11 from the first working state, and is in a downward arching and upward concave state, with the arc top structure turned downward, and the upward concave part forming the first transverse channel 3 for supporting the cable from above.

[0020] The two functions of "height-adjustable guiding" and "transverse supporting and converging" are realized by one component, i.e., the arc-shaped cable support 2, greatly simplifying the internal structure of the weak current box and solving the problems of space congestion and high cost caused by the installation of multiple different function cable organizers in the traditional scheme.

[0021] Dynamic adaptability and double protection of ports and cables: in the first working state, the cable guiding height can be adjusted by rotating, perfectly adapting to the uneven and different layout of the ports behind modern network devices, fundamentally eliminating the cable forced bending caused by the mismatch of port heights, and ensuring that the cable is effectively supported at the moment of leaving the device port through precise height matching, thereby fundamentally avoiding the formation of a lever at the port connection due to the self-weight or external pulling of the cable, greatly reducing the transverse stress and torsion of the connector, effectively preventing the port from loosening, virtual welding or even damage, protecting the network ports of expensive optical modem, switch and other devices, and improving the connection reliability of the overall system and the service life of the devices; More importantly, the curvature of the cable groove 21 of the arc-shaped cable support 2 meets the safety curvature requirement of the minimum bending radius of the cable (especially optical fiber), and once the cable is placed in the cable groove 21, its bending shape is constrained and regulated by the curvature, thereby forcibly ensuring that the bending angle of the cable is always within a safe range, eliminating internal damage of the cable caused by forced bending, and minimizing the signal attenuation (bending loss) of high-speed cables, thereby ensuring the signal transmission quality.

[0022] The second working state creates a special first transverse channel 3 that is independent of the device ports, realizes the "second planning" of the cable, orderly converges and guides the cables from different devices to the cable management area on the side of the box, and realizes the leap from "point-to-point disordered connection" to "bus type orderly management".

[0023] As shown in FIG. 1, Figures 1-14 In some embodiments, the arc-shaped cable support 2 is flipped by 120 degrees to 180 degrees from the first working state to enter the second working state, and in the second working state, the arc-shaped cable support 2 and the adjacent component together form the first transverse channel 3 capable of accommodating at least one cable.

[0024] The functional flip angle range of the arc-shaped wire support 2 from the first working state to the second working state is 120 to 180 degrees, within which the "upper concave part" of the arc-shaped wire support 2 can be fully exposed upward and cooperates with the adjacent component (the blocking rod 12) to build the first transverse channel 3 with sufficient cross-sectional area; Referring to Figure 8 The angle limit of "not less than 120 degrees" ensures the minimum practical space that the first transverse channel 3 must have, avoids the problem of narrow channel and difficulty in putting or pressing the cables due to insufficient flip angle, and 180 degrees is the ideal angle for realizing the maximum space of the first transverse channel 3, which provides flexibility from "available" to "best" to allow selection of the most suitable flip angle according to the space on site, and maximizes the space utilization efficiency. In use, the arc-shaped wire support 2 as the first transverse channel 3 is first flipped to the best angle of the second working state, that is, 180 degrees, to facilitate wire passing, and at this time, the gap space is the largest. After the wiring of the wire rack support plate 1 is completed, the arc-shaped wire support 2 is then adjusted from 180 degrees to 120 degrees according to the number of cables inside the first transverse channel 3.

[0025] One end of the wire rack support plate 1 is also provided with a stop block 15 for limiting the arc-shaped wire support 2 flipped from the first working state to 180 degrees into the second working state.

[0026] As Figures 1-14 shown, in some embodiments, the adjacent component is a blocking rod 12 fixed to one end of the wire rack support plate 1, the blocking rod 12 is provided with a rounded corner at the edge corner, the number of the blocking rod 12 is consistent with and one-to-one corresponds to the arc-shaped wire support 2 and is arranged in intervals; The blocking rod 12 and the arc-shaped wire support 2 in the second working state are arranged staggered in the length direction of the wire rack support plate 1, a gap is formed therebetween for the cables led out from the arc-shaped wire support 2 to enter the first transverse channel 3, and the blocking rod 12 laterally limits the cables led out from the arc-shaped wire support 2 adjacent thereto.

[0027] The blocking rod 12 and the arc-shaped wire support 2 are one-to-one corresponding and arranged in intervals, the blocking rod 12 is fixed to one end of the wire rack support plate 1 and is staggered with the arc-shaped wire support 2 in the second working state in the length direction to form a specific gap; The stop bar 12 cooperates with the dynamic arc-shaped cable holder 2 to clearly define the physical boundary of the "first transverse channel 3", transforming a conceptual channel into a structurally stable physical channel. The stop bar 12 is specifically designed to limit the movement of cables that extend from its adjacent arc-shaped cable holder 2, preventing them from moving laterally within the first transverse channel 3 or escaping from the channel, ensuring the neatness and stability of the wire harness. The "notch" formed serves as a dedicated entrance for cables entering the first transverse channel 3, providing clear path guidance. The "rounded corners" of the stop bar 12 completely eliminate the risk of scratching or damaging the cable sheath, enhancing the safety and reliability of the product.

[0028] As shown in Figures 1-14 some embodiments, in the first working state, the effective adjustment rotation angle range of the arc-shaped cable holder 2 is 0-70 degrees. In the first working state, the arc-shaped cable holder 2 in the up-arched and down-concave posture forms a second transverse channel 4 with the wire holder tray 1.

[0029] In the first working state, the effective adjustment angle of the arc-shaped cable holder 2 is 0-70 degrees. In this state, the "down-concave part" of the arc-shaped cable holder 2 naturally forms a "second transverse channel 4" with the wire holder tray 1. Figure 7 In the first working state, referring to Figure 7 , the arc-shaped cable holder 2 is rotated by 60 degrees from the lowest point to the highest point of the wire slot 21. Continuing to rotate by 10 degrees, the wire slot 21 can still support the cable. After 70 degrees, the wire slot 21 starts to descend from the highest point to the second working state. The adjustment range of 0-70 degrees covers the height difference of most device ports, providing high design margin and universality.

[0030] The wiring rack structure has bidirectional management capability in the first working state: Vertically, the wire slot 21 provides exclusive and height-adjustable vertical guidance for the cable of the current device port; Transversely, the "second transverse channel 4" formed by the down-concave part and the wire holder tray 1 has a function far beyond simple cable management. It is an open public cable passage that runs through the device array, allowing cables that do not belong to the current device area (such as optical fibers entering from above, network cables entering from the side, or connection cables jumping to remote devices) to pass through the channel in a hidden and orderly manner, without the need to fly over the devices or occupy the front operation space.

[0031] The separation of "device direct connection cables" and "in-box transition cables" in space reduces the intersection and accumulation of cables, not only improving the aesthetics, but also physically reducing the risk of interference between different types of cables (such as strong and weak electricity). It provides installers with higher wiring flexibility, and when facing complex low-voltage box environment, installers can flexibly dispatch and route various cables like planning urban traffic, so as to achieve the optimal neat layout.

[0032] As shown in Figures 1-14 some embodiments, in the first working state, the arc-shaped cable holder 2 is rotated to adjust the guide height of the wire slot 21, and at the same time, the outgoing direction of the cable guided by the wire slot 21 changes, thereby causing the longitudinal landing point of the cable after leaving the guide to continuously shift laterally; The distance between adjacent two arc-shaped cable holders 2 is less than the width of the wire slot 21, so as to allow at least one of the arc-shaped cable holders 2 to be dynamically designated as the first lateral channel 3 or a double-row port for adapting to the longitudinal direction.

[0033] As shown in Figures 1-14 some embodiments, the arc-shaped cable holders 2 are arranged in groups of three, and the arc-shaped cable holder 2 in the middle is configured to be reversible to the second working state to receive the cables guided from the arc-shaped cable holders 2 on both sides of the group.

[0034] The "continuous lateral shift" effect means that a single arc-shaped cable holder 2 can achieve accurate positioning of a single cable in two-dimensional space (height and left-right position), which is not achieved by traditional cable organizers; Referring to Figure 9 , the distance between the cables drawn between the two adjacent ports at the back of the device is usually greater than that of a cable, and the distance between the adjacent two arc-shaped cable holders 2 is less than the width of the wire slot 21, so that the two arc-shaped cable holders 2 on the outermost sides of the arc-shaped cable holders 2 arranged in groups of three can correspond to the cables drawn by the two adjacent ports at the back of the device, and the arc-shaped cable holder 2 in the middle can be reversed as the first lateral channel 3, realizing the "compact layout and three options" mode innovation. It realizes dynamic allocation of functions by physically reserving redundancy in advance, which ensures that at least one available lateral bus channel can be ensured in the most severe case of extremely high port density, solves the fundamental contradiction between compact design and functional completeness, and greatly improves the reliability and adaptability of the wiring architecture.

[0035] Please continue to refer to Figure 9 When there are two rows of vertically opposite ports at the back of the device, the mode exhibits another level of intelligence. Since the distance between adjacent arc-shaped cable holders 2 is less than the width of the cable (compact layout), the arc-shaped cable holder 2 in the middle does not need to be reversed to the second working state, but in the first working state, by adjusting its height, it can serve the upper port; Cables from the upper port can smoothly enter the cable groove 21 of the intermediate arc-shaped cable support 2, which has been adjusted to the appropriate height, with only a very small, natural lateral bend; Cables from the lower port can be directly guided by the arc-shaped cable support 2 on the adjacent side of the middle arc-shaped cable support 2, so that one of the three adjacent arc-shaped cable support 2 can be flipped to serve as the first horizontal channel 3, and the two adjacent arc-shaped cable support 2 can be adapted to the two vertically opposite ports by adjusting their height. Regardless of whether the device port layout is a complex "two-dimensional matrix" or a simple "one-dimensional single row", this cabling architecture can find the optimal cabling path through its dynamic adjustment and function allocation mechanism, thereby ensuring extremely high consistency and reliability in various real-world scenarios.

[0036] like Figures 1-14 As shown, in some embodiments, an angle positioning mechanism 5 is also included to lock the arc-shaped wire clamp 2 at a preset angle; The angle positioning mechanism 5 includes a plurality of limiting grooves 51 formed in the circumferential direction of the hinge shaft 11 and an oblong hole 52 provided at one end of the arc-shaped wire support hoop 2, wherein the oblong hole 52 is movably sleeved with the hinge shaft 11. One end of the inner wall of the waist-shaped hole 52 is provided with a spring piece 53, and the other end of the inner wall is provided with a limiting pin 54 that is adapted to the limiting groove 51. The spring piece 53 continuously abuts against the hinge shaft 11 with its elastic force, causing the waist-shaped hole 52 of the arc-shaped wire guide 2 to displace, so that the limiting pin 54 is stably engaged in the limiting groove 51 of the hinge shaft 11.

[0037] Using the space provided by the waist-shaped hole 52, the limit pin 54 is stably pressed into the limit groove 51 of the hinge shaft 11 by the continuous elastic force of the spring piece 53. The elastic force is used to achieve continuous locking without shaking or abnormal noise, and the locked state is stable and reliable.

[0038] like Figures 1-14 As shown, in some embodiments, the axial direction of the limiting pin 54 is parallel to the length direction of the waist-shaped hole 52, and its position is centrally located relative to the waist-shaped hole 52. The inner width of the limiting groove 51 is greater than the diameter of the limiting pin 54, so that the limiting pin 54 only contacts the edge of the groove opening of the limiting groove 51.

[0039] The axial direction of the limiting pin 54 is parallel to the length direction of the oblong hole 52, and its position is centered relative to the oblong hole 52. This design means that unlocking requires active application of axial tension, while vibration and pulling during normal use will not cause it to come off accidentally, achieving the effect of "easy to unlock and difficult to open by mistake". The entire locking and unlocking process does not require any tools and can be completed with one hand, greatly improving the installation and maintenance experience.

[0040] By designing the slot width of the limiting slot 51 to be greater than the diameter of the limiting pin 54, when the user applies a non-axial deflection force to attempt to unlock, the contact point will form a fulcrum, generating a huge lever jamming effect (self-locking), making unlocking extremely difficult or even impossible, which forces the user to perform the correct axial operation, a clever "foolproof" design. This lever effect provides an additional, huge holding force for the locked state in the non-operating state, further enhancing the stability of the mechanism in a vibrating environment.

[0041] As shown in Figures 1-14 some embodiments, one end of the limiting pin 54 is arranged on the inner wall of the waist-shaped hole 52, and two auxiliary pins 55 are also symmetrically arranged on both sides of the limiting pin 54, and the axial direction of the two auxiliary pins 55 is parallel to the length direction of the waist-shaped hole 52; when the limiting pin 54 is inserted into the limiting slot 51, the two auxiliary pins 55 are also inserted into the corresponding limiting slot 51 on the hinged shaft 11.

[0042] The two auxiliary pins 55 are symmetrically arranged on both sides of the limiting pin 54, and the three pins are inserted into the limiting slot 51 group to form a stable three-point support system. When subjected to a deflection force, the two auxiliary pins 55 interact with the wall of the limiting slot 51 to effectively share and resist the torque that causes the mechanism to disengage. The "line contact" defense of a single limiting pin 54 is upgraded to a "surface defense" of three pins. The lever jamming effect described above is amplified from a point to a surface, making it almost impossible to unlock in the wrong way, thereby ensuring the stability of the working state.

[0043] In actual use, the cable arranged in the wire slot 21 may exert an arbitrary direction and unpredictable "misalignment load" on the arc-shaped wire holder 2 due to its own gravity, bundling, or accidental pulling. The key is that the direction of these random and inclined forces is almost impossible to be the axial direction of the limiting pin 54. This interference will immediately trigger the lever jamming effect described above.

[0044] As shown in Figures 1-14 some embodiments, the inner wall of the wire slot 21 of the arc-shaped wire holder 2 is provided with a plurality of rubber blocks 22 on both sides for elastically clamping the cable in the wire slot 21. The outer side of the arc-shaped wire holder 2 is provided with an operation mark 23 for indicating the axial direction of the limiting pin 54 to guide the user to apply force in that direction to achieve angular unlocking. One end of the spring plate 53 close to the hinged shaft 11 is arc-shaped, and the two ends of the wire holder plate 1 are also provided with connecting ear plates 13, and the inside of the connecting ear plates 13 is provided with "8" shaped hanging holes 14.

[0045] The rubber blocks 22 provide flexible clamping force, which can prevent the cable from sliding or jumping out of the wire groove 21, and avoid the indentation damage caused by rigid clamping, which is particularly important for the protection of optical fibers. The arrangement of a plurality of rubber blocks 22 facilitates the pressing of the cable into the wire groove 21 and the leading of the cable out, and the flexible clamping force applied to the cable is also distributed in multiple points.

[0046] The operation mark 23 converts the internal invisible precision mechanical structure (the length direction of the waist-shaped hole 52 or the axial direction of the limiting pin 54) into an external visible visual instruction, so that the user can understand the correct force direction at a glance, avoid damage to the mechanism caused by misoperation, and greatly improve the usability of the product.

[0047] The "arc piece" design of the end of the elastic sheet 53 increases the contact area with the hinge shaft 11, makes the pressure distribution more uniform, avoids stress concentration, improves the service life and working stability of the elastic sheet 53, and ensures the reliability of the angle positioning mechanism 5 in long-term use.

[0048] A smart weak current box structure supporting modular expansion includes a weak current box body 6 and the wiring architecture, and the inside of the weak current box body 6 is provided with at least one modular layer plate 61, and the wire rack support plate 1 is detachably installed in the weak current box body 6 through the connecting lug plate 13.

[0049] As shown in Figures 1-14 some embodiments, vertical stands 62 are fixed on the inner walls of both sides of the inside of the weak current box body 6, a plurality of mounting hole positions 63 are arranged on the vertical stands 62 at a standard interval, and long strip-shaped holes 64 are arranged on both sides of the modular layer plate 61 correspondingly. By passing the long strip-shaped holes 64 through the different mounting hole positions 63 on the vertical stands 62, the height position and the front and back position of the modular layer plate 61 in the weak current box body 6 can be flexibly adjusted and fixed, which enables the user to easily adapt to network equipment of different sizes (such as optical modem, router, switch, etc.), and through the height-adjustable and front and back position-adjustable modular layer plate 61, the three-dimensional space in the box is flexibly planned. It perfectly adapts to network equipment of different sizes and depths, optimizes the heat dissipation air duct and the wiring space, and cooperates with the innovative wiring architecture to upgrade the weak current box body 6 from a fixed container to a modular system that can be freely expanded and reorganized according to needs, and completely solves the industry pain points of poor compatibility and inconvenient expansion of traditional weak current boxes.

[0050] As shown in Figures 1-14 some embodiments, a plurality of inclined holes 65 are further formed in the top of the modular layer plate 61, which facilitates the use of fixing members such as cable ties to fix the equipment on the modular layer plate 61.

[0051] As shown in Figures 1-14As shown, in some embodiments, a plurality of hanging nails 66 and fixing holes 67 are provided on one side of the upright 62 corresponding to the tail end of the modular shelf 61. The cable tray 1 is hung on the hanging nails 66 through the hanging holes 14 inside the connecting ear. The position of the cable tray 1 can be adjusted according to the position of the modular shelf 61 to guide and support the cables leading out from the port at the back of the equipment. This design allows the entire cabling structure to be installed as a whole component, which can be easily installed into or removed from the main body 6 of the low-voltage box, greatly facilitating initial installation and subsequent maintenance.

[0052] like Figures 1-14 As shown, in some embodiments, vertical cable management racks 68 are also provided on both sides of the inner wall of the back of the low-voltage box. All cables that are gathered and led out from the "first horizontal channel 3" and "second horizontal channel 4" of the cabling structure are naturally guided to the vertical cable management racks 68 on both sides for final bundling and fixing, thereby completing the neat and orderly cable management from the equipment port to the outlet.

[0053] In summary, the independently rotatable arc-shaped cable clamp 2 and its dual-working-state design significantly improve cable management efficiency. In the first working state, its arched and concave posture can dynamically adjust the guiding height of the cable tray 21 to adapt to the equipment port layout, eliminate forced bending of cables, and protect the ports from stress damage. Its concave part and the cable rack support plate 1 form a through-type second transverse channel 4, realizing three-dimensional separation of direct connection cables and transition cables. In the second working state, the upper concave part of the flipped arc-shaped cable clamp 2 and the stop bar 12 work together to form the first transverse channel 3, realizing the orderly convergence of multiple cables. Combined with the compact layout design, the guiding and convergence functions can be dynamically allocated. The precision angle positioning mechanism 5 achieves stable locking through the anti-jamming design, effectively solving the problems of cable cross-entanglement, easy interference, and difficult maintenance in traditional weak current boxes.
