Description

Technical Field

[0001] This invention relates to the field of communication cabinet wiring technology, specifically a modular wiring type outdoor communication cabinet. Background Technology

[0002] With the rapid development of 5G communication, the Internet of Things, and smart city construction, outdoor communication cabinets, as the core physical carrier of access layer networks, are widely deployed in scenarios such as streets, rooftops, parks, and outdoor base stations. They undertake multiple tasks including equipment housing, wiring harness management, environmental control, and outdoor protection.

[0003] However, existing outdoor communication cabinets typically only have simple cable trays or cable ties to secure power lines, fiber optic cables, and various signal lines. With equipment upgrades and increased business volume, the number of cable bundles inside the cabinet has surged, and different types of bundles (high-voltage, low-voltage, and fiber optic cables) often become tangled and cross each other. This "bundled" cabling leads to: dense and messy bundles blocking airflow, causing a localized heat island effect and affecting equipment stability; maintenance personnel need to spend a significant amount of time untangling the bundle paths, especially at night or during emergency repairs, posing a high risk of misoperation; and when adding new lines, the lack of dedicated pre-installed channels often necessitates cutting old cable ties and rewiring the entire system, which can easily damage existing bundle insulation or optical fibers, and results in a long construction period. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a modular cable-bundled outdoor communication cabinet, which mainly solves the problem that the wiring inside the existing communication cabinet is basically bundled in a simple way, resulting in poor heat dissipation efficiency and high maintenance difficulty.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A modular cable harness type outdoor communication cabinet includes a communication cabinet body, and further includes: an electrical appliance placement cavity and a cable harness placement cavity opened inside the communication cabinet body, wherein at least one cable harness placement cavity is provided, and side maintenance doors are hinged to both sides of the communication cabinet body; A wire harness arrangement rack is installed inside the communication cabinet, and the wire harness arrangement rack serves as the boundary line between the electrical appliance placement cavity and the wire harness placement cavity; A modular wire harness sorting board, comprising a wire harness sorting clamp, wherein the wire harness sorting clamp is installed on one side of the wire harness arrangement frame located in the wire harness placement cavity, and the wire harness sorting clamp is used to position and arrange the wire harnesses. A wire harness snap-in detection component is installed inside the wire harness sorting clamp to identify the snap-in status of the wire harness.

[0006] As a further embodiment of the present invention, the wire harness arrangement frame includes two supporting connecting frames fixedly installed on the inner wall of the communication cabinet. The supporting connecting frames have multiple positioning through holes evenly opened in the vertical direction. Multiple wire harness snap-fit ​​plates are evenly distributed between the two supporting connecting frames in the vertical direction. Each wire harness snap-fit ​​plate has a sliding rod slidably mounted in the sliding groove at both ends. The outer end of the sliding rod can be inserted into the positioning through hole. By cooperating with the positioning through hole, the height of the wire harness snap-fit ​​plate can be adjusted. A ventilation and heat dissipation gap is reserved between adjacent wire harness snap-fit ​​plates.

[0007] As a further embodiment of the present invention, each of the wire harness snap-fit ​​plates has a slot on its top surface for accommodating the wire harness, and each slot corresponds to each wire harness.

[0008] As a further embodiment of the present invention, the wire harness arrangement frame further includes a limiting pressure plate disposed between the two supporting connecting frames. The limiting pressure plate is located above the corresponding wire harness snap-fit ​​plate. The bottom surface of the limiting pressure plate is provided with an arc-shaped wire-catching groove corresponding to the snap-fit ​​groove of the wire harness snap-fit ​​plate. The limiting pressure plate and the wire harness snap-fit ​​plate fit together to form a clamping of the wire harness. The limiting pressure plate includes two guide rails symmetrically installed on the top surface of the limiting pressure plate. Each guide rail has a hook slidably connected inside. The hook is curved, and the end of the hook away from the guide rail is inserted into the positioning through hole.

[0009] As a further embodiment of the present invention, the wire harness sorting plate further includes a connecting support frame disposed between the two supporting connecting frames. The connecting support frame is slidably connected to the supporting connecting frame via insert rods symmetrically and laterally slidably connected at both ends. The side of the wire harness sorting clamp away from the connecting support frame has a wire-clamping groove corresponding to the slot of the wire harness snap-fit ​​plate. The side of the wire harness sorting clamp away from the connecting support frame has two wire-pressing plates rotatably connected via a positioning shaft. The wire-pressing plates have wire-clamping grooves at positions corresponding to the slots of the wire harness sorting clamp. The wire-pressing plates and the wire harness sorting clamp cooperate with each other to fix the wire harness. Each of the two pressure plates has a second alignment magnetic block fixedly connected to its opposite end, and the two second alignment magnetic blocks are magnetically connected.

[0010] As a further embodiment of the present invention, the wire harness sorting clamp has two sets of bending grooves symmetrically opened on the side near the connecting support frame. Each set of bending grooves has multiple expansion grooves connected end to end. The expansion grooves are used for bending the wire harness sorting clamp. A crimping strip is fixedly connected to the side of the wire harness sorting clamp near the connecting support frame. A limit slot is opened on the connecting support frame at the position corresponding to the crimping strip. The crimping strip is inserted into the limit slot.

[0011] As a further embodiment of the present invention, a first alignment magnetic block is fixed at both ends of the wire harness sorting clamp for bonding and fixing the two ends of the wire harness sorting clamp.

[0012] As a further embodiment of the present invention, the wire harness snap-fit ​​detection component includes multiple clearance slots, each of which is located inside each wire-clamping slot of the wire harness categorization clamp. A force-applying plate is slidably connected inside the clearance slot. A positioning cylinder is fixedly connected to the side of the wire harness categorization clamp near the connecting support frame at a position corresponding to the wire-clamping slot. A connecting post is provided inside the positioning cylinder. One end of the connecting post penetrates the surface of the wire harness categorization clamp and is fixedly connected to the force-applying plate. Two expansion plates are symmetrically arranged on the surface of the connecting post. The expansion plates are inclined, and one end of each expansion plate is connected to the connecting post.

[0013] As a further embodiment of the present invention, multiple positioning rails are uniformly distributed and fixedly connected inside the positioning cylinder, and a slip ring is provided inside the positioning cylinder. The slip ring is slidably connected to the positioning rail, and a convex ring is fixedly connected to the outer surface of each expansion plate. The convex ring and the slip ring are in contact with each other.

[0014] As a further embodiment of the present invention, the surface of the wire harness sorting clamp is evenly provided with multiple positioning slots, each positioning slot is provided with a display plate, both ends of the display plate are equipped with torsion spring shafts, a fixed shaft is fixedly connected inside the display plate, a connecting rope is attached to the surface of the fixed shaft, and the other end of the connecting rope is connected to the connecting post.

[0015] Compared with the prior art, the present invention provides a modular cable-stayed outdoor communication cabinet, which has the following advantages: 1. This invention uses a wire harness arrangement rack to divide the cabinet into independent electrical appliance storage chambers and wire harness storage chambers, achieving complete physical isolation between strong and weak current circuits and eliminating interference from cross-connections. Simultaneously, the wire harnesses are centrally stored in dedicated chambers, preventing obstruction of equipment cooling vents. The wire harness clip plate allows for free height adjustment through the cooperation of sliding rods and positioning through holes, and ventilation gaps are reserved between adjacent shelves to ensure smooth air convection inside the wire harness chambers and prevent interference with the cooling ducts of the electrical appliance chambers. This structural double protection ensures a low-temperature operating environment within the cabinet, effectively extending the service life of electrical equipment.

[0016] 2. This invention utilizes rubber material and features continuous expansion grooves, along with first alignment magnetic blocks at both ends. When inspecting the lower layer of wire harnesses, simply bend the upper clamping plate to shrink it into a flat ring shape and magnetically fix it. This allows the upper layer of wire harnesses to be completely retracted, freeing up space for the lower layer's operation without removing any binding structures. Simultaneously, each wire harness is individually clamped by a pressure plate and a second alignment magnetic block. Adjusting or inspecting a single wire harness only requires separating the corresponding magnetic block, without disturbing the other fixed wire harnesses. After inspection, simply unfold the clamping plate and re-insert the crimping strip to restore the original shape. The entire process is tool-free, reusable, and significantly improves the efficiency of layered maintenance in confined outdoor environments.

[0017] 3. This invention integrates a mechanically triggered detection assembly consisting of a force-applying plate, an inclined expansion plate, a slip ring, and a display panel. When the wiring harness is pressed into place, the force-applying plate pushes the expansion plate into the positioning cylinder. After the expansion plate is released from the clamping plate, it elastically resets and strikes the cylinder wall, producing a crisp "click" sound, providing auditory feedback. Simultaneously, the displacement of the connecting column pulls the display panel on the torsion spring shaft via an elastic rope, causing it to flip from a wide-side-outward orientation to a narrow-side-outward orientation, providing continuous visual indication of the wiring harness's position. When replacing the wiring harness, a tool is used to push the force-applying plate into the bottom of the clearance groove, causing the expansion plate to be compressed and reset by the slip ring, thus deactivating the indication.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] Please see Figures 1-14 As shown, a modular cable harness type outdoor communication cabinet includes a communication cabinet body 1. The interior of the communication cabinet body 1 is divided into an electrical appliance placement cavity 101 and a cable harness placement cavity 102 by a cable harness arrangement rack 2. The electrical appliances and cable harnesses are completely physically separated, eliminating cross-interference between strong and weak current lines. The left and right sides of the cabinet body are hinged with side maintenance doors 103, which can be used to inspect and repair the corresponding area of ​​cable harnesses or equipment without having to fully open the cabinet door, making it convenient to operate in narrow outdoor installation scenarios.

[0028] The existing communication cabinets have wire harnesses and electrical appliances mixed together, and the wire harnesses block the heat dissipation vents of the equipment. By using an independent wire harness placement cavity 102, all wire harnesses are centrally stored, and the heat dissipation ducts of the equipment are unobstructed, thus solving the problem of heat accumulation inside the cabinet from the source.

[0029] like Figures 3 to 11 As shown, the main body of the wire harness arrangement frame 2 includes two sets of left and right support connecting frames 201. The support connecting frames 201 have multiple positioning through holes 202 vertically and densely arranged. The positioning through holes 202 serve as the adjustment reference for the support connecting frames 201. A wire harness clip plate 203 is provided between the two sets of support connecting frames 201. When assembling the wire harness clip plate 203, first insert the slide rod 20301 into the slide groove at both ends of the wire harness clip plate 203, so that the slide rod 20301 can slide laterally inside the wire harness clip plate 203. Then place the wire harness clip plate 203 between the two support connecting frames 201, so that the slide rod 20301 slides vertically inside the positioning through hole 202 until it moves to a suitable height. Then move the slide rod 20301 laterally, so that the positioning through hole 202 can lock the height of the wire harness clip plate 203, so that the adjacent wire harness clip plates 203 have a ventilation gap to ensure air circulation between layers. Each wire harness clip plate 203 has a row of independent slots on its top surface, with one slot corresponding to one wire harness, so as to realize the initial column placement of wire harnesses.

[0030] like Figures 5 to 8 As shown, when assembling the limiting crimping plate 204: a hook 20402 is installed in the top guide rail 20401 of the limiting crimping plate 204. The hook 20402 can slide laterally in the guide rail 20401. The limiting crimping plate 204 and the wire harness clamping plate 203 are installed in the same way and are fixed by insertion through the corresponding positioning through hole 202. The distance between the limiting crimping plate 204 and the wire harness clamping plate 203 can be changed by vertically moving the limiting crimping plate 204. The arc-shaped wire clamping groove on the bottom surface of the limiting crimping plate 204 corresponds to the groove of the wire harness clamping plate 203. The upper and lower parts cooperate to clamp the wire harness and prevent the wire harness from shaking and loosening.

[0031] Specifically, during wire harness installation, all wire harnesses are first inserted into the individual slots of each wire harness clip plate 203 according to their functional zones, completing the initial alignment. Then, the installation position of the wire harness clip plates 203 is adjusted based on the overall height of the wire harnesses after alignment. Once the position is determined, the limiting pressure plate 204 is fixed using the same positioning and locking method, ensuring that the corresponding upper and lower slots tightly engage the corresponding wire harnesses. The number of wire harness clip plates 203 layers can be increased or decreased at any time according to on-site wiring needs, adapting to different capacity wiring requirements. Simultaneously, the reserved ventilation gaps ensure that the heat generated during wire harness operation dissipates smoothly, reducing the risk of heat accumulation inside the cabinet.

[0032] The number of wiring harness layers can be freely adjusted, the shelf height is adjustable, and the modular assembly and disassembly are possible without the need to completely disassemble the cable tray. It is suitable for different wiring harness usage scenarios such as 5G base stations and park monitoring.

[0033] like Figures 5 to 10 As shown, it also includes a wire harness sorting board 3, which includes a connecting support frame 301; The two ends of the connecting support frame 301 are slidably snapped between the supporting connecting frame 201 by horizontal insert rods, which is the same as the installation method of the wire harness snap plate 203. It can move vertically along the supporting connecting frame 201 to adapt to the height of the wire harness snap plate 203. The wire harness sorting clamp 302 has an integrally formed crimping strip 304 on the back. The crimping strip 304 is embedded in the limiting slot 303 of the connecting support frame 301 to complete the basic fixation of the wire harness sorting clamp 302. After being limited by the wire harness clamping plate 203, the wire harness extends towards the wire harness sorting clamp 302. The wire harness can be limited again through the wire clamping groove on the surface of the wire harness sorting clamp 302, thus completing the zoning and sorting of the wire harness, avoiding multiple wire harnesses from intertwining and making it easier to quickly locate the target wire harness during subsequent inspection and maintenance.

[0034] When there is a multi-layer wire harness classification clamp 302, the wire harnesses on the upper layer are closer to the side maintenance door 103, so that the multi-layer wire harnesses are stacked, which makes it easier to first determine the layer height of the wire harness and then determine the position of the wire harness when locating the wire during maintenance.

[0035] like Figure 6 As shown, in order to prevent the upper wire harness from obstructing the lower wire harness during maintenance, the wire harness categorization clamp 302 can be bent. The wire harness categorization clamp 302 is made of rubber, so that the multiple wire harnesses inside the wire harness categorization clamp 302 form a flat ring. The wire harness categorization clamp 302 has multiple sets of expansion grooves 305 on one side. The expansion grooves 305 can bend the two ends of the wire harness categorization clamp 302 towards the center. When the wire harness categorization clamp 302 is bent, part of the crimping strip 304 will be pulled out from the inside of the limiting groove 303.

[0036] like Figures 4 to 10 As shown, the wire harness sorting clamp 302 is equipped with first alignment magnetic blocks 307 at both ends. When the wire harness sorting clamp 302 is bent, it can be magnetically fixed at both ends by the first alignment magnetic blocks 307. The wire harness sorting clamp 302 has a wire slot on one side, which is rotatably mounted with two sets of wire clamping plates 306 via a positioning shaft 308. After the wire harness is placed into the wire slot, the two wire clamping plates 306 are snapped inward. The second alignment magnetic blocks 309 at the end of the wire clamping plates 306 attract each other, clamping and fixing each wire harness individually. No cable ties are needed, the original wiring is not disturbed, and the outer sheath of the wire harness is not scratched.

[0037] After the wire harness is inserted into the slot of the wire harness sorting clamp 302, the clamping plates 306 on both sides are rotated to magnetically engage the second alignment magnetic blocks 309 at the ends of the clamping plates 306. This individually positions each wire harness within its corresponding slot, completing the sorting and fixing of the wire harness. When it is necessary to adjust the position of a single wire harness or perform maintenance, simply separate the second alignment magnetic blocks 309 of the corresponding clamping plate 306, flip open the clamping plate 306, and the corresponding wire harness can be removed without interfering with the other fixed wire harnesses, reducing the difficulty of wire harness sorting. When routine maintenance of the lower-level wire harnesses is required, simply bend the wire harness categorization clamp 302 with force. This causes the clamp to contract and deform inward along multiple expansion slots 305 until the first alignment magnetic blocks 307 at both ends of the clamp 302 come into contact and attract each other. This fixes the clamp 302 into a flat ring shape. The wire harnesses originally stacked on top are bent and gathered together with the clamp, making room for the lower-level wire harnesses and preventing obstruction of their maintenance. After maintenance, separate the first alignment magnetic blocks 307, stretch the clamp 302 flat, and then press the detached crimping strip 304 back into the corresponding limiting slot 303 to restore its original position. The entire process does not require untying the original binding structure, making it convenient to operate, reusable, and suitable for the maintenance needs of multi-layered wire harness arrangements inside outdoor communication cabinets.

[0038] It also includes a wire harness connection detection component 4; like Figures 12 to 13 As shown, each wire harness sorting clamp 302 has a clearance groove 401 inside its wire clamping slot, and a slidable force-applying plate 402 is installed inside the clearance groove 401. A positioning cylinder 404 is fixed on the side of the wire harness sorting clamp 302 away from the wire clamping slot. A connecting post 403 passes through the positioning cylinder 404. One end of the connecting post 403 is connected to the force-applying plate 402. An expansion plate 405 is obliquely fixed on the end of the connecting post 403 near the positioning cylinder 404. The expansion plate 405 is made of a composite plastic material with high toughness. A positioning rail 406 is installed on the inner wall of the positioning cylinder 404. A slip ring 407 slides along the positioning rail 406. A protruding ring 408 on the outer wall of the expansion plate 405 fits against the slip ring 407. The display panel 409 is mounted on the surface of the clamping plate via a torsion spring shaft 410. Normally, the wide side of the display panel 409 faces outwards. When the wire harness is inserted into the wire slot, the position of the connecting post 403 changes, and the connecting rope 411 pulls the fixing shaft 412. The connecting rope 411 is made of elastic rope, which causes the display panel 409 to flip to the narrow side facing outwards, thus visually reminding the operator whether the wire harness is properly engaged.

[0039] In use, initially, both the connecting post 403 and the expansion plate 405 are located inside the wire harness sorting clamp 302. The force plate 402 initially protrudes from the inner surface of the wire clamping groove. When the wire harness is pressed into the groove, it pushes the force plate 402, causing the connecting post 403 to move towards the positioning cylinder 404. During this process, the inclined expansion plate 405 enters the positioning cylinder 404. When the expansion plate 405 leaves the wire harness sorting clamp 302, it will recover its original shape due to its own resilience. Figure 13 In the instant of resetting, the expansion plate 405 will make a crisp "click" sound as it impacts the cylinder wall, reminding the operator that the wire harness is properly engaged. When replacing a wire harness and inserting a new one, if... Figure 12 As shown, due to the depth of the recessed groove 401, after the old wire harness is removed from the wire clamping groove, a sharp object is used to push the force plate 402 further into the recessed groove 401. The expansion plate 405 will drive the convex ring 408 to push towards the slip ring 407 until the convex ring 408 contacts the slip ring 407. The slip ring 407 then squeezes the convex ring 408, causing the expansion plate 405 to contract until the force plate 402 can no longer be pushed. At this point, the connecting rope 411 will be stretched. Subsequently, relying on the rebound force of the torsion spring shaft 410 and the contraction of the connecting rope 411, the connecting post 403 and the force plate 402 will be reset, pulling the expansion plate 405 back into the wire harness classification clamp 302, thus resetting the position and facilitating the insertion of a new wire harness.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
