Description

Technical Field

[0001] The present invention relates to the technical field of computer data cables, and more particularly to a 360-degree rotatable computer data cable connector. Background Art

[0002] In scenarios like industrial automation and precision measurement, computer data cables must maintain stable signal transmission over long periods of time to ensure the real-time and accuracy of critical information such as PLC control instructions and sensor monitoring data. However, existing computer data cable connectors are often designed with fixed angles or limited rotation ranges, making it impossible to stabilize the cable at the optimal twist or bend angle for actual use.

[0003] This design flaw causes numerous problems in practical applications: when data cables are unexpectedly bent or twisted excessively due to natural droop, human contact, or equipment vibration, the internal stranding structure of the conductors can be damaged, and the shielding layer may break or loosen, leading to increased signal reflection and attenuation. For example, if the twist pitch of the twisted pair of an Ethernet cable changes due to a sudden angle change, its electromagnetic interference (EMI) resistance will be significantly reduced, causing signal crosstalk and increased network data loss. If the bending angle of an optical fiber data cable exceeds the safety threshold, it may cause the fiber core to break or cause communication interruption due to refraction loss of the optical signal, seriously affecting precision instruments that rely on high-speed data transmission. In the industrial control field, unstable cable angles can also cause delays or errors in command transmission between PLCs and actuators, affecting the synchronization and accuracy of the production line. For medical equipment, which requires extremely stable signals, interruptions in data transmission can even lead to diagnostic errors or equipment failure. Furthermore, long-term, unintended bending can accelerate the aging of the internal structure of data cables, shortening their service life and increasing equipment maintenance costs. With the advancement of Industry 4.0 and smart manufacturing, equipment is placing increasing demands on data cable signal transmission stability and anti-interference capabilities. The angle adjustment limitations of existing connectors have become a bottleneck restricting system performance. Therefore, developing a connector that can rotate 360° and secure the data cable within a safe angle range is urgently needed to ensure reliable signal transmission in complex scenarios. To address this, we propose a 360° rotatable computer data cable connector. Summary of the Invention

A buckle is provided on one side of the inserting arc, and a plurality of through-holes distributed in a ring array are opened on the buckle, and the inserting arc is inserted through the through-holes.

[0006] Preferably, the end of the serial port connector is provided with a curved slope, the inserted arc is in a circular arc shape as a whole, the curved arc of the outer wall of the inserted arc is in contact with and limited by the outer side of the curved slope, the outer periphery of the inserted arc is provided with a fixed plate fixed to the inner wall of the connecting cover, and the fixed plate is provided with a through groove for constraining the inserted arc to rotate with the center of the curved arc as the center of the circle.

[0007] Preferably, the insert arc is made of elastic metal material, the cross-section of the spring-pressing ring is an arc corresponding to the insert arc, and the buckle is a circular ring with a notch.

[0008] Preferably, the pressing mechanism also includes a fixing buckle for constraining the sliding direction of the buckle, and the buckle is connected to a constraining protrusion at one end away from the spring-pressing ring. One side of the fixing buckle is fixed to the inner wall of the connecting cover, and a pressure column is provided on one side of the fixing buckle. The pressure column passes through the connecting cover and is connected to a sliding seat.

[0009] Preferably, the slide seat and the connecting cover slide in a limited manner, a sliding lock buckle is slidably provided on the outer side of the slide seat, and a plurality of sliding lock grooves adapted to the sliding lock buckle are provided on the connecting cover.

[0010] Preferably, an integral sliding sleeve is connected between the outer peripheries of the plurality of sliding seats, and the integral sliding sleeve is a multiple concave-convex ring structure.

[0011] Preferably, the data line body consists of a spring-pull section and a long connecting section, the long connecting section has an outer layer of rubber material, the spring-pull section is made of elastic latex material, the spring-pull section is in the shape of a wave with redundant line sections, and the inner wall of the connecting cover is fixed to the end of the long connecting section near the spring-pull section.

[0012] Preferably, a tightening sleeve is fixed to the outer periphery of the long connecting section, and the tightening sleeve is made of elastic material.

[0013] Preferably, a plurality of ridges are provided on the outer circumference of the twisting sleeve, and the plurality of ridges are distributed in a circular array with the twisting sleeve as the center, and a twisted channel is formed between adjacent ridges.

[0014] Preferably, the twisted channel consists of an outer flared opening, a bite opening and an inner air pressure opening, the inner air pressure opening is in the shape of a narrow bottle body, the bite opening is located at the bottle mouth position of the inner air pressure opening and is in the shape of an inward convex spacing reduction, the outer flared opening is located on the outside of the bite opening, and the outer flared opening is in the shape of a trumpet with decreasing diameter from the outside to the inside.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention achieves 360° rotation without dead angles through the precise matching of the threading universal ball and the inner spherical surface of the serial port connector. The connector orientation can be flexibly adjusted according to the usage scenario to avoid damage to the internal wire twisting structure and breakage of the shielding layer due to forced bending of the data cable. The plug-in mechanism locks the optimal angle, reduces core wire stress and signal reflection, and ensures a stable data transmission rate of 5Gbps under the USB protocol. It is especially suitable for narrow spaces or equipment vibration environments, reduces the risk of communication interruption caused by improper angles, and solves the problems of weak data line signal transmission stability and anti-interference ability.

[0016] 2. The present invention also adopts elastic metal material through arc insertion, which absorbs pulling force through its own deformation when subjected to force, and the fixed plate groove restrains its excessive deformation; the triple overlapping wave structure of the spring pressure ring synchronously disperses external force and reduces the impact on the connection part. The elastic pulling section of the data line is in the form of latex wave, and the internal redundant line expands with the pulling, converting external force into elastic potential energy to avoid direct stress and strain on the core wire. The double buffer mechanism effectively reduces the probability of solder joint breakage and line damage, thereby extending the service life of the connector.

[0017] 3. The present invention also drives multiple slides to move synchronously through an integrated sliding sleeve, pushes the pressure buckle to rotate through the pressure column, uses the lever principle to complete the extrusion of the spring ring with a small stroke, adapts to the small space design of the end, and mechanically engages and locks the sliding lock buckle and the sliding lock groove to avoid loosening due to vibration. The concave and convex ring structure enhances the grip friction, facilitates the perception of operation nodes, solves the cumbersome problems of traditional positioning operations, and realizes "push-rotate-lock" in one step, taking into account both adjustment efficiency and positioning stability.

[0018] 4. The present invention also adopts a highly elastic material for the twisted outer sleeve on the periphery of the long connecting section, and the convex ridges in the annular array form a multi-directional support. When subjected to force, adjacent convex ridges squeeze and twist each other to prevent excessive bending. When the bending angle is ≤90°, the natural curvature of the core wire can still be maintained to avoid damage to the insulation layer or breakage of the core wire. Combined with the buffering effect of the elastic pulling section, the fatigue resistance of the data cable in frequent bending scenarios is improved, and the signal attenuation caused by sudden changes in shape is reduced.

[0019] 5. The twisted grooves between adjacent convex ridges of the present invention guide the teeth of mice to enter through the outer flared opening. The convex structure inside the bite pressure opening cooperates with the elastic outer cover to form a reverse clamping force on the teeth. The narrow bottle shape of the inner air pressure opening limits the space for teeth to move, causing discomfort and avoiding them. No chemical agents are required. The physical design effectively reduces the risk of damage to the wire body by biting in rodent-active areas such as forests, thereby expanding the outdoor application scenarios of data cables.

DETAILED DESCRIPTION

[0032] like Figures 1 to 11 As shown, the present invention relates to a 360° rotatable computer data cable connector, comprising a USB connector 1, a serial port connector 2 being provided on one side of the USB connector 1, and a data cable body 3 being connected between the serial port connector 2 and the USB connector 1; USB connector 1 adopts Type-A standard interface design. The shell is made of H62 brass material through precision stamping and nickel-plated on the surface, which not only ensures wear resistance during plugging and unplugging, but also has good electromagnetic shielding performance. The internal pins are high-purity oxygen-free copper (purity ≥99.95%), and the contact resistance is reduced by gold plating process (≤20mΩ), ensuring the stability of high-speed data transmission; the inside of the interface is integrated with an anti-misplug guide groove, combined with a spring-type snap-on structure, the plug-in force is controlled within the range of 3-5N, compatible with USB2.0 / 3.0 protocols, data transmission rate can reach up to 5Gbps, and supports hot plugging function.

[0033] Serial port connector 2 adopts DB9 standard serial port design. The shell is zinc alloy die-casting and the surface is chromate treated for corrosion resistance. The 9 pins are made of phosphor bronze to ensure stable contact pressure after long-term plugging and unplugging. The welding area at the end of the pin is tin-immersion treated to improve the welding reliability with the data cable body 3. A stress relief sleeve is set at the tail of the connector, which is tightly combined with the data cable body 3 through a heat shrink process. It can withstand large axial tension and prevent the solder joints from breaking due to external force.

[0034] The data cable 3 uses a four-core shielded structure: the positive and negative power wires are 22AWG (0.32mm²) multi-stranded copper wire (number of strands ≥ 16), ensuring a maximum carrying current of 2.5A; the data transmission line is 28AWG (0.08mm²) twisted pair cable (twist pitch 10-15mm), which effectively suppresses differential mode interference. The entire cable is wrapped with an aluminum foil Mylar shield layer (aluminum foil thickness ≥ 0.03mm) and a tinned copper braid (coverage ≥ 85%). The double shielding design ensures that the anti-electromagnetic interference capability meets EMC Class B standards.

[0035] A hollow threading universal ball 4 is provided at one end of the data line body 3. The threading universal ball 4 is embedded in the terminal of the serial port connector 2. The line can pass through the threading universal ball 4, thereby cooperating with the threading universal ball 4 to achieve a 360° rotation. The data cable body 3 is equipped with a connecting cover 5 at one end close to the threading universal ball 4. The connecting cover is injection-molded with ABS engineering plastic and has reinforcing ribs on the inner wall. It is tightly combined with the sheath of the data cable body 3 through ultrasonic welding technology to form an IP54-level dust-proof and waterproof seal, which can resist dust intrusion and splashing during daily use; the plug-in mechanism 6 integrated inside the connecting cover 5 is the core component for achieving stable connection between the threading universal ball 4 and the serial port connector 2. Its structural design takes into account both connection reliability and rotation flexibility.

[0036] The insertion mechanism 6 includes multiple insertion arcs 601, the surface of the insertion arcs 601 is polished (Ra≤0.4μm) to reduce the rotational friction coefficient, and a spring ring 602 is arranged between one end of the multiple insertion arcs 601. The spring ring 602 is stamped and formed by spring steel, and the overall structure is annular. The cross-section is a triple overlapping wave shape. It is tempered at low temperature to ensure the elastic limit and can withstand long-term compression and rebound cycles without failure. Its inner wall is equidistantly arranged with multiple groups of pressing mechanisms 7 along the circumference. The number of pressing mechanisms 7 corresponds to the number of insertion arcs 601. The buckle 701 of each group of pressing mechanisms 7 is a polyoxymethylene (POM) injection molded part. The buckle 701 can be driven manually or by external equipment. The contact point between the end of the buckle 701 and the inner wall of the spring ring 602 is fixed by glue (using temperature-resistant epoxy glue) to ensure that the pressure is transmitted synchronously when the spring ring 602 is deformed.

[0037] A buckle ring 8 is provided between one side of the plurality of insertion arcs 601 . The buckle ring 8 is provided with a plurality of through holes distributed in a ring array, and the insertion arcs 601 are inserted through the through holes.

[0038] Working principle: The threading universal ball 4 adopts a hollow structure, with an internal through-hole for the data cable 3 to pass through. Its outer spherical surface is precisely matched with the inner spherical surface of the serial port connector 2, which can achieve 360° rotation without dead angles. When in a narrow space or when the connector direction needs to be adjusted, the threading universal ball 4 can flexibly rotate with the twisting of the data cable 3 to avoid damage to the line due to forced bending of the wire. It can also adapt to insertion in different situations, such as narrow spaces, etc., while reducing the plug-in and unplugging stress of the connector and the device interface, providing adaptability for different usage scenarios.

[0039] Angle fixation and communication stability guarantee; 1. First, insert USB connector 1 into the device interface to complete the initial connection.

[0040] 2. Manually press the buckle 701 of the pressing mechanism 7, and the buckle 701 transmits the external force to the spring ring 602, causing the spring ring 602 with the triple overlapping wavy cross-section to shrink and deform.

[0041] 3. The contraction of the spring ring 602 drives the multiple insert arcs 601 to open outward synchronously, separating them from the through holes of the buckle 8 and releasing the circumferential limit.

[0042] 4. Rotate the connecting cover 5 to the optimal angle where the distortion of the data line 3 is minimized. At this time, the stress of the core wire inside the wire is released and the signal transmission path is stable.

[0043] 5. Release the buckle 701, and the spring ring 602 returns to its original shape due to the elasticity of the spring steel, pushing the arc 601 to be reinserted into the through-hole of the buckle 8, and the angle locking is achieved through the close fit between the arc 601 and the through-hole.

[0044] During this process, the wavy structure of the spring ring 602 ensures continuous and stable radial pressure, so that the arc 601 maintains reliable contact with the buckle 8, avoiding angular deviation due to vibration or slight pulling. At the same time, the rotation characteristics of the threading universal ball 4 reduce the signal attenuation caused by wire twisting, and the angle fixing function of the insertion mechanism 6 avoids the risk of breakage caused by long-term stress on the core wire. The two work together to reduce the probability of communication interruption and improve the stability and efficiency of network data transmission. It is especially suitable for scenarios with high requirements for communication continuity, such as industrial control and equipment debugging.

[0045] The above-mentioned arc insertion 601 only plays a role in positioning and fixing, and lacks a buffering protection effect. In order to achieve anti-pull buffering protection of the end part, the following structure is designed.

[0046] The end of the serial port connector 2 is provided with a curved slope 201, and the insert arc 601 is an arc in shape as a whole. The curved arc of the outer wall of the insert arc 601 is in contact with and limited by the outer side of the curved slope 201. The outer periphery of the insert arc 601 is provided with a fixing plate 603 fixed to the inner wall of the connecting cover 5. The fixing plate 603 is provided with a groove for constraining the insert arc 601 to rotate with the center of the curved arc as the center of the circle.

[0047] The insert arc 601 is made of elastic metal material, the cross section of the spring ring 602 is an arc corresponding to the insert arc 601, and the pressing buckle 701 is a circular ring with a notch.

[0048] Working principle: During the positioning process, the insert arc 601 rotates along the groove of the fixed plate 603 with the center of the arc as the center of the circle, and the notched circular ring structure of the buckle 701 matches the corresponding curvature of the spring-pressing ring 602. When the buckle 701 is pressed, the spring-pressing ring 602 is forced to shrink, driving the insert arc 601 to rotate synchronously. At this time, the outer wall of the insert arc 601 is in contact with the outer side of the curved slope 201 at the end of the serial port connector 2, and the insertion or separation with the buckle 8 is realized during rotation to complete the positioning operation. This rotary insertion positioning method enables the horizontal or vertical pulling force to act on the insert arc 601, and its rotation center can disperse the force, thereby preventing the insert arc 601 from easily separating from the buckle 8, thereby ensuring the stability of the positioning.

[0049] When the end part is subjected to pulling force, since the arc 601 is made of elastic metal, it will undergo a certain degree of elastic deformation. Under the action of pulling force, the arc 601 will produce a slight expansion or contraction or bending along its arc trajectory, and absorb part of the pulling force through its own elastic deformation, thereby playing a buffering role. At the same time, the groove of the fixed plate 603 constrains the rotation range of the arc 601 to prevent it from being damaged due to excessive deformation. The triple overlapping wavy cross-section of the spring ring 602 can also cooperate with the elastic deformation of the arc 601 to further disperse and buffer external forces, reduce the influence of pulling force on the connection between the data line body 3 and the serial port connector 2, thereby effectively protecting the end part and reducing the risk of line damage or communication interruption due to pulling.

[0050] In summary, the rotational positioning of the insert arc 601 ensures the reliability of angle fixation, while its elastic properties and the coordination of various components achieve anti-pull buffer protection. The combination of the two improves the durability and communication stability of the data cable connector.

[0051] Although the above method can position the arc 601 and the retaining ring 8, the positioning operation is relatively troublesome and cannot be performed conveniently. In view of this, the following structure is designed.

[0052] The pressing mechanism 7 also includes a fixed buckle 702 for constraining the sliding direction of the buckle 701. The end of the buckle 701 away from the elastic ring 602 is connected to a constraining protrusion 703. The constraining protrusion 703 prevents excessive movement and the buckle 701 from sliding out. One side of the fixed buckle 702 is fixed to the inner wall of the connecting cover 5. A pressure column 704 is provided on one side of the fixed buckle 702. The pressure column 704 passes through the connecting cover 5 and is connected to a sliding seat 705.

[0053] The slide 705 and the connecting cover 5 slide in a limited position, and a sliding lock buckle 706 is provided on the outer side of the slide 705. The connecting cover 5 is provided with multiple sliding lock grooves 707 adapted to the sliding lock buckle 706. An integrated sliding sleeve 708 is connected between the outer peripheries of the multiple slides 705, and the integrated sliding sleeve 708 is a multiple concave and convex ring structure.

[0054] Working principle: When it is necessary to adjust the positioning status of the arc insert 601 and the buckle 8, the operator pushes the integrated sliding sleeve 708 (the multiple concave and convex ring structure is convenient for gripping and exerting force), driving multiple slides 705 to slide along the connecting cover 5. When the slide 705 moves, the pressure column 704 connected to it synchronously passes through the connecting cover 5 and applies thrust to the constraint protrusion 703. After the constraint protrusion 703 is subjected to force, it drives the buckle 701 to move. At this time, the fixed buckle 702 (fixed to the inner wall of the connecting cover 5) constrains the sliding direction of the buckle 701, ensuring that the buckle 701 rotates along the preset trajectory with the center of the circle as the axis. Since the pressing buckle 701 is a circular ring with a notch and adopts a center-of-center rotation design, compared with a linear push-type structure, it can complete the squeezing of the spring ring 602 within a smaller moving stroke. The rotation action of the pressing buckle 701 can amplify the force on the spring ring 602 through the lever principle, reducing the displacement required for the operation, and perfectly adapting to the small volume space limitation of the end of the computer data cable. After being squeezed, the spring ring 602 shrinks and deforms, driving the insert arc 601 to rotate out of the perforation of the buckle 8, thereby releasing the positioning state.

[0055] When the connecting cover 5 is rotated to the optimal angle and needs to be fixed in position, the integrated sliding sleeve 708 is pushed in the reverse direction to reset the slide 705, and the pressure column 704 releases the thrust on the constraining protrusion 703. The spring ring 602 elastically resets and pushes the insert arc 601 to rotate and insert into the through hole of the buckle 8. At this time, the sliding lock buckle 706 on the outside of the sliding slide 705 is inserted into the corresponding sliding lock groove 707 on the connecting cover 5. The position of the slide 705 is fixed by the mechanical locking structure, and then the state of the pressure buckle 701 and the spring ring 602 are locked, ensuring that the insert arc 601 and the buckle 8 are firmly positioned. The multiple concave and convex ring structures of the integrated sliding sleeve 708 not only improve the grip friction, but also can feedback the operating stroke through the concave and convex texture, making it easier for the operator to perceive the positioning state switching node. Multiple slides 705 are linked through the integrated sliding sleeve 708 to ensure that all pressing mechanisms 7 move synchronously, avoiding positioning deviation caused by uneven force on a single buckle 701, thereby greatly improving the operational convenience and positioning reliability.

[0056] Although the above-mentioned structure has a buffering effect against pulling, the design of the data line 3 does not have a redundant buffer section, and it may still cause damage to the internal part when pulled. In view of this, the data line 3 is supplemented with a design.

[0057] The data line 3 consists of an elastic section 301 and a long connecting section 302. The long connecting section 302 has an outer layer of rubber material, and the elastic section 301 is made of elastic latex. The elastic section 301 is a wavy body with redundant line segments, and the line inside the wavy body of the redundant line segment is also wavy. This combines with the elasticity of the latex to give it a redundant amount as a whole, and provides a buffer section at the end when pulling occurs. The inner wall of the connecting cover 5 is fixed to the end of the long connecting section 302 near the elastic section 301.

[0058] Working principle: The long connecting section 302 serves as the main part of the data line 3. It adopts a rubber outer layer, has good flexibility and wear resistance, and can meet the use requirements in conventional wiring scenarios. Its end close to the elastic pull section 301 is fixed to the inner wall of the connecting cover 5 to form a stable connection fulcrum, ensuring that the pulling force can be effectively transmitted to the elastic pull section 301 for buffering.

[0059] The elastic section 301 is made of highly elastic latex material and is wavy in shape as a whole. The internal redundant line section is also wavy in design. This structure gives the elastic section 301 a natural expansion margin. When the data line 3 is pulled, the external force is transmitted to the elastic section 301 through the long connecting section 302. The latex material will be stretched and deformed due to its own elasticity. The outer layer of the wavy shape and the internal wavy line body will expand synchronously, converting the pulling force into elastic potential energy. During the stretching process, the redundant wavy structure provides a buffer space for the wire body, preventing the wire body from directly bearing severe pulling force. When the pulling force disappears, the elastic recovery force of the latex material causes the elastic stretching section 301 to shrink back to the wavy shape, and the internal wire body is also reset, ensuring the integrity of the line and the stability of signal transmission. This design allows the elastic pulling section 301 at the end of the data cable 3 to act as a buffer section when it is pulled. It absorbs the pulling energy through elastic deformation and redundant structure, greatly reducing the risk of the internal cable being pulled and damaged. Combined with the anti-pull buffering effect of the arc 601, the durability of the entire data cable connector is further improved.

[0060] The data line 3 mentioned above has a buffer section, but its effectiveness is relatively low. When it is subjected to external force, the line is easily bent.

[0061] A tightening sleeve 303 is fixed to the outer periphery of the long connecting section 302. The tightening sleeve 303 is made of elastic material. A plurality of convex ridges 304 are provided on the outer periphery of the tightening sleeve 303. The plurality of convex ridges 304 are distributed in a circular array with the tightening sleeve 303 as the center.

[0062] Furthermore, if used in areas with a large number of rodents (such as areas with a large number of trees), in order to increase the anti-gnawing effect, a twisted channel is formed between adjacent convex ridges 304. The twisted channel consists of an outer flared opening 401, a bite pressure opening 402 and an inner air pressure opening 403. The inner air pressure opening 403 is in the shape of a narrow bottle body. The bite pressure opening 402 is located at the bottle mouth position of the inner air pressure opening 403 and is in the shape of an inner convex space with a reduced spacing. The outer flared opening 401 is located on the outside of the bite pressure opening 402. The outer flared opening 401 is in the shape of a trumpet with a decreasing diameter from the outside to the inside.

[0063] Working principle; 1. Anti-bending constraint mechanism; The twist-tightening jacket 303 on the outer periphery of the long connecting section 302 is made of a highly elastic material (such as modified TPU), and the convex ridges 304 distributed in a circular array on its outer periphery form a multi-directional support structure. When the data cable body 3 is twisted or bent by external force, the sides of adjacent convex ridges 304 contact each other and are squeezed. The rigid profile of the convex ridges 304 stores stress through elastic deformation, forming a mutually twisted constraint force, which prevents the jacket from excessively bending in a single direction. This design enables the long connecting section 302 to maintain the natural curvature of the core wire inside the cable body when subjected to a bending force of ≤90°, avoiding core wire breakage or insulation layer damage due to severe bending. Combined with the buffering effect of the elastic pulling section 301, the overall bending resistance is improved.

[0064] 2. Rodent-proof mechanism; For rodent-active areas such as forests, the twisted channels between adjacent convex ribs 304 are specially designed to form a physical repellent structure. The outer flared opening 401 is trumpet-shaped (the diameter decreases from the outside to the inside), and its inclination angle (optimally 30°-45°) is adapted to the bite angle of rodent incisors, guiding the teeth along the slope into the groove; When the rodent's teeth penetrate into the bite opening 402, the inner convex space-reducing structure and the elastic material of the tightening jacket 303 work together to: The teeth squeeze the two side walls of the bite opening 402, causing the elastic cover to deform and generate a reverse clamping force, which continuously squeezes the two sides of the teeth. The narrow bottle shape of the inner air pressure port 403 further limits the space for teeth to move, and combined with the clamping force of the bite pressure port 402, it makes mice feel uncomfortable (such as tooth pressure pain) when biting, forming a conditioned reflex to avoid.

[0065] This design does not require the addition of chemical repellents. Through the combination of physical structure and animal behavior, it effectively reduces the risk of damage to the wire caused by rodent gnawing without affecting the flexibility of the wire. It is suitable for complex environments such as outdoor and forest areas.

[0066] In summary, the twist-tightening jacket 303 solves the problem of data cable fragility under complex working conditions through the dual mechanism of "convex diamond twisting to prevent bending + channel physical anti-bite", thereby extending the service life of outdoor use.
