Description

Technical Field

[0001] This invention relates to the field of wire harness management technology, and in particular to a multi-channel signal cable harness with adjustable limiting channels. Background Technology

[0002] In scenarios such as electronic equipment assembly, computer room wiring, and desktop wiring, a large number of signal and communication lines are laid out in a concentrated manner. In order to avoid messy, tangled, and worn lines, and to improve the neatness of the lines and the convenience of later maintenance, it is usually necessary to use cable management equipment to classify, store, and fix multiple signal lines.

[0003] Currently, most conventional cable bundlers on the market are one-piece snap-on structures, Velcro cable ties, or fixed single-channel cable bundle holders, which have several technical drawbacks: First, most cable bundlers have fixed channel specifications, making them unable to adapt to signal cables of different diameters, resulting in poor versatility and problems such as loose cable bundle clamping or damage to the cables due to excessive compression; second, conventional cable bundles have a single fixing method, mostly only suitable for fixed installation scenarios, and cannot be flexibly fixed to common wiring locations such as desktop sides, and the stability of cable bundle limiting and fixing is poor, easily leading to cable bundle displacement, loosening, and falling off after long-term use. Therefore, this paper proposes to develop a multi-channel signal cable bundle with adjustable limiting channels. Summary of the Invention

[0004] In view of the above-mentioned problems, the purpose of this invention is to provide a multi-channel signal cable bundler with adjustable limiting channels, which solves the technical problems of traditional cable bundlers such as non-adjustable channels, cumbersome cable bundle disassembly and assembly, poor wire diameter adaptability, and inability to independently control single bundles, and achieves the effect of independent storage of multiple channels, adaptive compression, convenient disassembly and assembly, and flexible fixation.

[0005] The present invention is achieved by the following technical solution: a multi-channel signal cable bundler with adjustable limiting channels, comprising a cable bundler bracket, two decorative covers, a fixing component, an adjusting component, and multiple airbag components; The cable tray is the main load-bearing structure of the device, consisting of a hollow pentagonal support shell and multiple signal line channels. The multiple signal line channels are evenly distributed on the outside of the support shell and are integrally injection molded with the support shell. Each group of signal line channels is equipped with a set of movable baffles that can be flexibly opened and closed to realize the independent installation and removal of a single signal line. The two decorative covers are symmetrically snapped onto the front and rear ends of the cable tie bracket, respectively, to cover the internal assembly structure of the cable tie bracket; The fixing component and the adjusting component cooperate with each other to form an adjustable clamping and fixing mechanism for the whole device. The airbag assembly is fitted into the inner cavity of the signal line channel, enabling independent adaptive compression of a single wire harness.

[0006] As a further improvement to the above solution, each side plate of the support housing is provided with a positioning socket for positioning and assembling the airbag assembly, and a limit slot is provided in the inner cavity of the support housing at the front and rear symmetrical positions corresponding to each positioning socket.

[0007] As a further improvement to the above solution, the signal line channel is a hollow isosceles triangle structure with a channel opening on its outer side. Two sets of limiting sleeves are symmetrically arranged on one side of the channel opening, and a limiting baffle is fixed on the other side.

[0008] As a further improvement to the above solution, the movable baffle assembly includes a baffle, an elastic steel sheet, and a pin. One side of the baffle is integrally formed with a connecting sleeve, which is hinged between two sets of limiting sleeves by a pin. The other side of the baffle is provided with a locking block that matches the limiting baffle. The elastic steel sheet is symmetrically assembled at the gap between the baffle and the signal line channel.

[0009] As a further improvement to the above solution, the baffle is opened and closed by rotation at 0°-0° via a pin. The elastic steel sheet is made of highly elastic stainless steel and is in a pre-compression state after assembly, which is used to realize automatic springback reset after the baffle is pressed open.

[0010] As a further improvement to the above solution, the airbag assembly includes an airbag, a valve core, and a pressure ring; the valve core is assembled at the bottom of the airbag and inserted and fixed into the inner cavity of the positioning socket, and the pressure ring is threaded onto the outer wall of the valve core.

[0011] As a further improvement to the above solution, the airbag is made of highly elastic silicone material, the valve core is a one-way air intake and pressure relief structure, and the outer end of the valve core extends to the inner cavity of the support housing for inflation and depressurization by an external air pump.

[0012] As a further improvement to the above solution, the clamping ring achieves a sealed fixation between the valve core and the positioning socket through threaded locking, preventing the valve core from loosening and leaking air.

[0013] The beneficial effects of this invention are as follows: This invention uses an inflatable airbag assembly as a compression structure, which can adjust the degree of airbag expansion according to the signal line diameter and the number of wires, adaptively adapting to signal lines of different specifications, solving the problem that traditional fixed wire harness channels cannot adapt to multi-diameter wire harnesses, and at the same time avoiding wire harnesses that are too loose and shifted or too tight and squeezed and damaged. The pentagonal distributed multi-channel structure of this invention enables the classified storage of wire harnesses, avoiding wire tangling and mess; the flexible airbag compression method is a soft contact that will not scratch or squeeze the outer sheath of the signal line, providing good protection for the wire harness. This invention features multiple independent signal line channels, coupled with an automatically resetable movable baffle assembly, enabling individual threading and unthreading of single signal lines without the need to disassemble the entire cable bundle structure. This reduces the difficulty of line maintenance and adding or removing cable bundles, making it suitable for complex wiring scenarios. Attached Figure Description

[0019] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] Please combine Figure 1-11 As shown in the figure, the present invention provides a multi-channel signal cable bundler with adjustable limiting channels. The device is mainly composed of a cable bundler bracket 1, two sets of symmetrically arranged decorative covers 2, a fixing component 3 for positioning and locking the whole machine, an adjusting component 4 for adjusting the clamping distance, and multiple sets of one-to-one adaptive clamping airbag components 5. Each component adopts a modular joint structure, with high overall assembly precision and strong structural linkage. Through the combination structure of multiple independent channels for separate storage, flexible opening and closing, flexible adaptive clamping of airbags, and adjustable threaded clamping and fixing, it completely solves the technical pain points of traditional cable bundlers such as mixed wire harnesses, interference during disassembly and assembly, single wire diameter compatibility, and loose fixing. It can be widely used in scenarios such as computer room cabinet cabling, office desktop wire harness organization, internal wire harness arrangement of precision electronic equipment, and industrial control equipment line storage. It is compatible with various wire materials such as round signal cables, flat communication cables, and composite wire harnesses of different thicknesses. like Figure 1-4As shown, the cable tie bracket 1 is the main structure supporting the cable tie, and the whole is made of high-strength flame-retardant ABS plastic through integrated injection molding. The main body of the cable tie bracket 1 is a hollow pentagonal support shell 11. The pentagonal symmetrical structure has excellent mechanical properties. Compared with circular and square structures, it can evenly distribute multiple signal line channels 12, maximize the use of the outer space, realize independent partition storage of multiple cable ties, and at the same time ensure that the whole machine is evenly stressed and there is no problem of unilateral tilting or offset after clamping and fixing. The five side plates of the support shell 11 are symmetrically and equally arranged. Each side plate has a rectangular positioning socket 111 in the center. The positioning socket 111 is a dedicated positioning and installation position for the airbag assembly 5. The diameter of the hole is the same as that of the valve core 52. Precise diameter matching enables rapid insertion and positioning of the airbag assembly 5, while ensuring coaxiality accuracy after assembly, avoiding displacement and leakage during inflation. The inner wall of the support housing 11 and the front and rear sides corresponding to each set of positioning ports 111 are symmetrically provided with strip-shaped limiting slots 112. The limiting slots 112 adopt a trapezoidal slot structure, which can be tightly engaged with the limiting protrusions 22 of the decorative cover 2 to form an anti-detachment and anti-shaking positioning structure, effectively limiting the left and right and up and down displacement of the decorative cover 2, and ensuring the sealing and stability of the decorative cover 2 after assembly. The hollow cavity structure inside the support housing 11 can reserve sufficient space for airbag inflation and wiring harness arrangement, and facilitate future wiring inspection and airbag maintenance and replacement. Multiple signal cable channels 12 are evenly arranged in a ring on the outer wall of the support housing 11, and are integrally injection molded with the support housing 11 without splicing gaps, resulting in excellent structural integrity and sealing. The signal cable channels 12 adopt a hollow isosceles triangular structure. Compared with circular and square channels, the open end of the triangular channel has wider adaptability, accommodating the insertion and storage of round, flat, and irregularly shaped cables. At the same time, the closed end of the triangular structure has higher structural strength, can stably bear the pressure of the cable bundle, and is not prone to deformation. Each group of signal cable channels 12 is an independent closed channel, isolated from each other and without interference. It can realize the individual storage of signal cables with different functions and specifications, completely avoiding the problems of multiple cable bundles tangling, friction and wear, and signal interference. The outer wall of the signal line channel 12 has a rectangular channel opening 121, which serves as a station for wire harness entry and exit and baffle assembly assembly. The width of the channel opening 121 is adapted to the outer diameter of the conventional signal line, taking into account both the convenience of wire threading and the stability of the limit. Two sets of coaxially arranged limit sleeves 122 are symmetrically fixed on the upper side of the channel opening 121. The inside of the sleeve is a smooth through hole for inserting the pin shaft 134, providing a rotation support reference for the baffle 131. A limit baffle 123 is fixed on the lower side of the channel opening 121. The end of the limit baffle 123 is provided with an arc-shaped locking structure, which can accurately fit and lock with the locking block at the end of the baffle 131, ensuring that there is no loosening or warping after the baffle is closed, and realizing the complete closure and limit of the signal line channel 12. The movable baffle assembly 13 is the core structure for enabling independent and quick assembly and disassembly of a single signal line. It is adapted to the independent assembly of each group of signal line channels 12, and can realize the independent opening and closing of a single channel without interference. The specific assembly process is as follows: First, align the integrally formed connecting sleeve 132 on one side of the baffle 131 with the coaxial through hole of the two groups of limiting sleeves 122, and insert the matching pin 134 to complete the hinge assembly. After assembly, the baffle 131 can rotate freely from 0° to 60° around the pin 134 to open and close. The rotation process is smooth without jamming or offset. Next, two highly elastic stainless steel sheets 133 are symmetrically embedded in the gap between the baffle 131 and the signal line channel 12. The two ends of the elastic steel sheets 133 are respectively pressed against the inner wall of the baffle 131 and the inner wall of the signal line channel 12. After assembly, the elastic steel sheets 133 are in a slightly pre-compressed state, providing stable elastic power for the baffle to reset. An arc-shaped locking block is integrally formed on the side of the baffle 131 away from the pin 134. The arc of the locking block is perfectly matched with the locking structure of the limiting baffle 123. In actual use, staff only need to manually press the outer end face of the baffle 131 inward. The elastic steel sheet 133 is compressed and deformed under force, and the baffle 131 rotates inward around the pin 134 to open the channel opening 121. A single signal cable can then be placed horizontally into the signal cable channel 12, or the cable harness that needs to be inspected or replaced can be directly pulled out. There is no need to disassemble the entire machine or remove other cable harnesses, making the disassembly and assembly operation extremely simple. Once the cable harness is in place, releasing the pressing force causes the elastic steel sheet 133 to instantly release its elastic potential energy, pushing the baffle 131 to automatically rotate back to its original position. The end block and the limiting baffle 123 are precisely locked together, automatically completing the channel closure limit without the need for manual alignment and closure. This automatic reset structure can effectively avoid the problem of cable harness falling off or being exposed due to incomplete manual closure, greatly improving the neatness of wiring and work efficiency. like Figure 1-3 As shown in Figure 10, the two sets of decorative covers 2 have a completely symmetrical structure and are detachably snapped onto the front and rear end faces of the wire harness bracket 1. They mainly serve to provide sealing protection, wire harness positioning, and airbag shielding protection. At the same time, they can also cover the internal assembly structure, improving the overall aesthetics of the device. The decorative cover 2 is also made of high-strength plastic in one piece, consisting of an assembly plate 21 and a cover plate 23. The outer dimensions of the assembly plate 21 are precisely matched with the inner cavity dimensions of the support housing 11, allowing it to be tightly embedded into the inner cavity of the support housing 11 for embedded assembly. The outer wall of the assembly plate 21 is integrally formed with limiting protrusions 22 that correspond one-to-one with the limiting slots 112. The limiting protrusions 22 adopt an elastic protrusion structure, which can be slightly squeezed and deformed during assembly to embed into the limiting slots 112. After embedding, they automatically spring back and lock, achieving a quick snap-fit ​​assembly without screws or glue. The assembly accuracy is high and the sealing performance is good, which can effectively prevent the decorative cover 2 from shaking back and forth or falling off. An outwardly protruding cover plate 23 is integrally connected to the outer side of the assembly plate 21. The outer diameter of the cover plate 23 is larger than the outer diameter of the end face of the support housing 11, which can completely cover the opening of the end face of the support housing 11, forming a closed storage cavity. This provides multiple protections for the internal signal lines and airbag components 5, including dustproofing, impact protection, and wear protection, preventing dust and debris from entering the cavity and affecting the performance of the wiring harness. At the same time, a ring pull ring 24 is integrally fixed to the outer wall of the cover plate 23. The pull ring 24 adopts an integrated arc structure with no sharp edges, providing a comfortable grip. When it is necessary to inspect or replace the internal airbags and wiring harnesses, the operator can directly grasp the pull rings 24 on both sides and pull them outward with even force to disengage the limiting protrusion 22 from the limiting slot 112, thereby quickly removing the decorative cover 2 and opening the internal cavity for maintenance. The disassembly and assembly are convenient and efficient, and can be repeatedly disassembled and reassembled without affecting the assembly accuracy. like Figure 1-6 As shown, the fixing component 3 and the adjusting component 4 cooperate to form an adjustable clamping and fixing mechanism for the entire device, enabling flexible fixing of the whole machine on installation carriers of different thicknesses such as desktops, equipment side panels, and cabinet frames. It has strong adaptability and high fixing firmness, which can effectively avoid the problem of the whole machine sliding, shifting, and falling during long-term use. The fixing component 3 adopts an integrated injection molding structure with no splicing assembly gaps, strong structural load-bearing capacity, and high stability. Specifically, it includes a connecting plate 31, an L-shaped clamping plate 32, and a positioning sleeve 33. Among them, the connecting plate 31 is integrated with the top corners of the two sets of signal line channels 12 at the bottom of the support shell 11, so that the fixing component 3 and the cable tie bracket 1 form an integrated force-bearing structure with uniform force distribution and no stress concentration, making it less prone to breakage and damage. The L-shaped clamping plate 32 is a right-angle bending structure, forming a U-shaped clamping station, which can be directly clamped onto the edge of various plate-type installation carriers, adapting to suspended and side-mounted wiring installation scenarios, without occupying the effective space of the desktop or equipment table. The positioning sleeve 33 is vertically and integrally fixed to the middle of the horizontal plate of the L-shaped clamping plate 32, and the inner cavity of the sleeve is provided with internal threads 34 throughout. The adjusting component 4 is matched and installed inside the positioning sleeve 33, including the adjusting rod 41 and the adjusting knob 42. The outer wall of the adjusting rod 41 is machined with external threads that match the internal threads 34, and the two form a precision thread transmission structure. The adjusting rod 41 can be vertically raised and lowered along the positioning sleeve 33. The adjusting knob 42 is integrally fixed to the bottom end of the adjusting rod 41. The outer wall of the knob is provided with anti-slip texture, which can effectively increase the friction of the hand and prevent slippage during adjustment. During actual installation and fixing, first, snap the L-shaped clamp 32 onto the upper edge of the mounting carrier, so that the inner side of the clamp fits against the upper surface of the carrier. Then, manually rotate the adjustment knob 42 to drive the adjustment rod 41 to feed downwards, so that the bottom end of the adjustment rod 41 presses tightly against the lower surface of the mounting carrier. Through the clamping force between the L-shaped clamp 32 and the adjustment rod 41, the whole machine is firmly fixed. For mounting carriers of different thicknesses, the lifting stroke of the adjustment rod 41 can be finely adjusted by rotating the adjustment knob 42 in both directions to adapt to the thickness of conventional plate carriers from 3mm to 30mm. After installation, the whole machine is firmly clamped without shaking or offset, which can meet the needs of long-term static wiring. When disassembling, simply unscrew the adjustment rod 41 in the opposite direction to remove the whole machine directly, making it convenient for relocation and reuse. like Figure 1-3 As shown in Figures 8 and 11, the airbag assembly 5 is the core functional structure for achieving adaptive flexible clamping of the wire harness. Multiple airbag assemblies 5 correspond one-to-one with the positioning sockets 111 of the support housing 11 and the wire harness storage channels, enabling independent adaptive clamping of a single wire harness. This solves the defects of traditional wire harnesses, such as rigid compression, poor adaptability, and unadjustable clamping force. The airbag assembly 5 includes a high-elasticity silicone airbag 51, a one-way air intake valve core 52, and a locking and sealing clamping ring 53. The overall assembly has good sealing performance, stable inflation, and is not prone to leakage, allowing for long-term repeated use. The specific assembly process is as follows: First, the metal clamping ring... Ring 53 is pre-fitted onto the outer wall of valve core 52. Then, the top end of valve core 52 is inserted through the outside of support housing 11 into the inner cavity of positioning socket 111, so that the outer end of valve core 52 remains in the hollow cavity of support housing 11, which facilitates subsequent inflation operation. The bottom end of valve core 52 is fixedly and sealed to the center of bottom of airbag 51. Finally, tighten the clamping ring 53 to fix valve core 52 inside positioning socket 111 by thread locking. This not only achieves structural positioning but also fills the assembly gap, and plays a role in sealing and preventing air leakage and loosening, thus preventing valve core displacement and air leakage failure during long-term use. The wire harness storage and clamping process is as follows: After the signal wires are threaded and stored and the decorative cover 2 is assembled and fixed, the operator can use a small manual air pump connected to the air inlet of the valve core 52 to inflate the air bag 51 at a uniform speed. The air bag 51 is a flexible and expandable silicone structure. After inflation, it can automatically and adaptively expand and deform according to the number and diameter of the wire harness in the inner cavity without hard compression damage. It can perfectly fit the outer curved surface of various signal wires and perform all-round flexible contact clamping on the wire harness stored in the inner cavity of the decorative cover 2 and the signal wire channel 12. By controlling the inflation volume, the clamping force can be precisely adjusted. When the inflation volume is small, it is suitable for thin wire harnesses and single wire harnesses. When the inflation volume is large, it is suitable for thick wire harnesses and multiple stacked wire harnesses. This completely solves the problem that traditional wire harnesses cannot adapt to multiple specifications of wires and the clamping force is uncontrollable. When it is necessary to inspect, add, remove, or replace signal lines, air can be released through the pressure relief structure of the valve core 52. After the internal air pressure of the airbag 51 decreases, it automatically contracts and resets, releasing the clamping limit on the wire harness. At this time, the movable baffle assembly 13 can be directly opened to complete the wire harness disassembly and assembly, making the operation convenient. At the same time, the flexible clamping method of the silicone airbag will not damage the outer sheath of the signal line, and has good insulation, cushioning, and wear resistance properties, which can effectively protect the wire harness, extend the service life of the wire harness, and meet the wiring protection requirements of precision electronic equipment. In summary, this invention, through optimized structural design, integrates three core functions: an independent opening and closing wire-threading structure, a threaded adjustable clamping and fixing structure, and an airbag adaptive flexible clamping structure. The overall structure is compact, robustly assembled, easy to operate, and adaptable to a wide range of scenarios. The multi-independent channel separate storage structure enables neat classification of wire harnesses, avoiding tangling and interference; the elastic automatic reset baffle significantly improves the efficiency of wire harness assembly and disassembly, supporting independent maintenance of individual wire harnesses; the adjustable clamping structure adapts to different mounting carriers, providing flexible and stable installation and fixing; the airbag adaptive clamping structure is compatible with all specifications of conventional signal cables, with controllable clamping force and damage-free protection; the overall molding process of the device is simple, the production cost is low, and it can be repeatedly disassembled and reused. Its stability and practicality far exceed traditional wire harnesses, possessing extremely high market promotion value and application prospects.
