Description

Technical Field

[0001] This invention relates to the field of computer data cable technology, and more specifically, to a 360° rotatable computer data cable connector. Background Technology

[0002] In industrial automation, precision measurement, and other applications, computer data cables need to maintain stable signal transmission over long periods to ensure the real-time performance and accuracy of critical information such as PLC control commands and sensor monitoring data. However, most existing computer data cable connectors are designed with a fixed angle or only have a limited range of rotation, making it impossible to stabilize the data cable at the optimal twisting or bending angle according to the actual usage scenario.

[0003] This design flaw causes numerous problems in practical applications: when data cables experience unexpected excessive bending or twisting due to natural sag, human contact, or equipment vibration, the twisted structure of the internal conductors is easily 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 pairs in an Ethernet cable changes abruptly due to an angle change, its electromagnetic interference (EMI) immunity will significantly decrease, causing signal crosstalk and increasing network data packet loss rates; if the bending angle of an optical fiber data cable exceeds a safe threshold, it may cause the fiber core to break or lead to communication interruption due to optical signal refraction loss, severely impacting precision instruments that rely on high-speed data transmission.

[0004] In industrial control, unstable cable angles can lead to delays or errors in command transmission between the PLC and actuators, affecting the synchronization and accuracy of the production line. For applications requiring extremely high signal stability, such as medical equipment, data transmission interruptions can even cause diagnostic errors or equipment malfunctions. Furthermore, prolonged unintended bending accelerates the aging of the data cable's internal structure, shortens its lifespan, and increases equipment maintenance costs.

[0005] With the advancement of Industry 4.0 and intelligent manufacturing, equipment demands increasingly higher stability and anti-interference capabilities for data cable signal transmission. The limitations of existing connector angle adjustment have become a bottleneck restricting system performance. Therefore, developing a connector that can rotate 360° and fix the data cable within a safe angle range has become an urgent need to ensure the reliability of signal transmission in complex scenarios. In light of this, we propose a 360° rotatable computer data cable connector. Summary of the Invention

[0006] The purpose of this invention is to provide a 360° rotatable computer data cable connector to solve the technical problems of weak signal transmission stability and anti-interference ability of data cables.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a 360° rotatable computer data cable connector, including a USB connector, a serial port connector is provided on one side of the USB connector, and a data cable is connected between the serial port connector and the USB connector;

[0008] One end of the data cable is provided with a hollow universal ball for threading, which is embedded in the serial port connector terminal. One end of the data cable is equipped with a connecting cover, and the connecting cover is connected to an insertion mechanism. The insertion mechanism consists of an insertion arc and a spring-loaded ring. The spring-loaded ring is a ring structure with an overlapping wave-shaped cross-section. The spring-loaded ring is made of elastic metal. Multiple pressing mechanisms are arranged on the inner wall of the spring-loaded ring. Each pressing mechanism includes a snap fastener, one end of which contacts the inner wall of the spring-loaded ring. A buckle is provided on one side of the insertion arc, and the buckle has multiple through holes arranged in a ring array. The insertion arc is inserted through the through holes.

[0009] Preferably, the end of the serial port connector is provided with a curved slope, the insertion arc is generally arc-shaped, the outer wall of the insertion arc is in contact with and limited by the outer side of the curved slope, and a fixing plate is provided on the outer periphery of the insertion arc to be fixed to the inner wall of the connecting cover. The fixing plate has a through groove to constrain the insertion arc to rotate around the center of the curved arc.

[0010] Preferably, the insert arc is made of elastic metal material, the cross-section of the spring-loaded ring is an arc corresponding to the insert arc, and the buckle is a ring with a notch.

[0011] Preferably, the pressing mechanism further includes a fixing buckle for constraining the sliding direction of the buckle. The end of the buckle away from the spring ring is connected to a constraining protrusion. One side of the fixing buckle is fixed to the inner wall of the connecting cover. One side of the fixing buckle is provided with a pressing post. The pressing post passes through the connecting cover and is connected to a sliding seat.

[0012] Preferably, the slide block and the connecting cover are limited to slide, a sliding lock buckle is slidably provided on the outer side of the slide block, and multiple sliding lock grooves adapted to the sliding lock buckle are provided on the connecting cover.

[0013] Preferably, an integral sliding sleeve is connected between the outer peripheries of the plurality of sliding blocks, and the integral sliding sleeve has a multi-layered concave-convex ring structure.

[0014] Preferably, the data cable consists of a spring-loaded section and a long connector section. The long connector section has a rubber outer layer, and the spring-loaded section is made of elastic latex material. The spring-loaded section has a wave-like shape with redundant line segments, and the inner wall of the connecting cover is fixed to the end of the long connector section near the spring-loaded section.

[0015] Preferably, a tightening sleeve is fixed to the outer periphery of the long connector, and the tightening sleeve is made of an elastic material.

[0016] Preferably, the outer periphery of the tightening jacket is provided with a plurality of protrusions, which are arranged in a circular array around the tightening jacket, and a twisting groove is formed between adjacent protrusions.

[0017] Preferably, the twisted channel consists of an outer flare, a biting opening, and an inner air-pressure opening. The inner air-pressure opening is in the shape of a narrow bottle body. The biting opening is located at the bottle mouth position of the inner air-pressure opening and has a convex shape with a reduced spacing. The outer flare is located outside the biting opening and has a trumpet shape with a decreasing diameter from the outside to the inside.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention achieves 360° rotation without dead angles by precisely matching the universal ball joint with the inner spherical surface of the serial port connector. The orientation of the connector can be flexibly adjusted according to the usage scenario, avoiding damage to the internal wire twisting structure and shielding layer breakage caused by forced bending of the data cable. With the help of the insertion mechanism to lock the optimal angle, the stress on the core wire and signal reflection are reduced, ensuring a stable data transmission rate of up to 5Gbps under the USB protocol. It is especially suitable for narrow spaces or equipment vibration environments, reducing the risk of communication interruption caused by improper angle, and solving the problems of weak signal transmission stability and anti-interference ability of data cables.

[0020] 2. This invention also utilizes an elastic metal material for the insertion arc, which absorbs tensile force through its own deformation when subjected to force, while the fixing plate through the groove constrains excessive deformation; the triple-overlapping wave structure of the spring pressure ring synchronously disperses external force, reducing the impact on the connection parts; the elastic pull section of the data cable is in the shape of latex waves, and the internal redundant circuitry unfolds with the pull, converting external force into elastic potential energy, avoiding direct stress and damage to the core wire; the dual buffer mechanism effectively reduces the probability of solder joint breakage and circuit damage, and extends the service life of the connector.

[0021] 3. This invention also uses an integrated sliding sleeve to drive multiple sliding blocks to move synchronously, and pushes the buckle to rotate through the pressure column. It uses the lever principle to complete the compression of the spring ring with a small stroke. It is adapted to the small space design at the end. The sliding lock buckle and the sliding lock groove are mechanically locked to prevent vibration and loosening. The concave and convex ring structure enhances the grip friction and facilitates the perception of operation nodes. It solves the problem of cumbersome traditional positioning operation and realizes "push-rotate-lock" in one step, taking into account both adjustment efficiency and positioning stability.

[0022] 4. The present invention also uses a highly elastic material for the outer circumferential tightening jacket of the long connector section, and the ring array of convex diamonds forms multi-directional support. When under force, adjacent convex diamonds squeeze and twist together to prevent excessive bending. When the bending angle is ≤90°, the core wire can still maintain its natural curvature, avoiding damage to the insulation layer or breakage of the core wire. Combined with the buffering effect of the elastic pull section, it improves the fatigue resistance of the data cable in frequent bending scenarios and reduces signal attenuation caused by abrupt changes in shape.

[0023] 5. The present invention uses a twisted groove between adjacent convex diamonds to guide rodent teeth into the groove through an outward flare. The inner convex structure of the biting opening cooperates with the elastic outer sleeve to form a reverse clamping force on the teeth. The narrow bottle shape of the inner hollow opening restricts the movement space of the teeth, causing them discomfort and prompting them to avoid the groove. No chemical agents are needed. Through physical design, the risk of damage to the cable from rodents in active areas such as forests is effectively reduced, expanding the outdoor application scenarios of the data cable.

[0038] like Figures 1 to 11 As shown, the present invention relates to a 360° rotatable computer data cable connector, including a USB connector 1, a serial port connector 2 on one side of the USB connector 1, and a data cable 3 connected between the serial port connector 2 and the USB connector 1.

[0039] USB connector 1 adopts a Type-A standard interface design. The shell is made of H62 brass through precision stamping and nickel plating, which ensures both wear resistance during insertion and removal and good electromagnetic shielding performance. The internal pins are made of high-purity oxygen-free copper (purity ≥99.95%), and the contact resistance is reduced (≤20mΩ) through gold plating to ensure the stability of high-speed data transmission. The interface integrates an anti-misinsertion guide groove on the inside, and with the spring-loaded latch structure, the insertion and removal force is controlled within the range of 3-5N. It is compatible with USB 2.0 / 3.0 protocols, and the data transmission rate can reach up to 5Gbps. It also supports hot-swapping.

[0040] The serial port connector 2 adopts the DB9 standard serial port design. The housing is made of zinc alloy die casting and the surface is treated with chromate to achieve corrosion resistance. The nine pins are made of phosphor bronze to ensure stable contact pressure after long-term insertion and removal. The soldering area at the end of the pins is treated with tin to improve the soldering reliability with the data cable 3. The connector tail is equipped with a stress relief sleeve, which is tightly connected to the data cable 3 through heat shrinking process. It can withstand greater axial tensile force and avoid the solder joint from breaking due to external force.

[0041] The data cable body 3 adopts a four-core shielded structure: the power supply positive and negative wires are 22AWG (0.32mm²) multi-strand twisted copper wires (strand count ≥16) to ensure a maximum current carrying capacity of 2.5A; the data transmission line is 28AWG (0.08mm²) twisted pair cable (twist pitch 10-15mm) to effectively suppress differential mode interference. The entire cable is wrapped with an aluminum foil Mylar shielding layer (aluminum foil thickness ≥0.03mm) and a tinned copper braided mesh (coverage ≥85%). This double shielding design enables the electromagnetic interference resistance to meet the EMC Class B standard.

[0042] One end of the data cable 3 is equipped with a hollow universal ball 4 for cable threading. The universal ball 4 is embedded in the terminal of the serial port connector 2, and the cable can pass through the universal ball 4. In this way, the universal ball 4 can achieve 360° rotation.

[0043] The end of the data cable 3 near the universal ball joint 4 is equipped with a connecting cover 5. The connecting cover is made of ABS engineering plastic injection molding and has reinforcing ribs on the inner wall. It is tightly combined with the sheath of the data cable 3 through ultrasonic welding process to form an IP54 dustproof and waterproof seal, which can resist dust intrusion and splashes in daily use. The insertion mechanism 6 integrated inside the connecting cover 5 is the core component for realizing a stable connection between the universal ball joint 4 and the serial port connector 2. Its structural design takes into account both connection reliability and rotation flexibility.

[0044] The insertion mechanism 6 includes multiple insertion arcs 601. The surface of the insertion arcs 601 is polished (Ra≤0.4μm) to reduce the coefficient of rotational friction. A spring-loaded ring 602 is provided between one end of the multiple insertion arcs 601. The spring-loaded ring 602 is made of spring steel and is formed by stamping. It has an overall ring structure with a triple-overlapping wave cross-section. It is subjected to low-temperature tempering to ensure the elastic limit and can withstand long-term compression and rebound cycles without failure. Multiple sets of pressing mechanisms 7 are arranged equidistantly along the circumference of its inner wall. The number of pressing mechanisms 7 corresponds to the number of insertion arcs 601. The buckle 701 of each set 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-loaded ring 602 is fixed by dotting (using high-temperature resistant epoxy glue) to ensure that the pressure is transmitted synchronously when the spring-loaded ring 602 deforms.

[0045] A retaining ring 8 is provided between one side of multiple insertion arcs 601. The retaining ring 8 has multiple through holes arranged in a ring array, through which the insertion arcs 601 are inserted.

[0046] Working principle: The universal ball 4 adopts a hollow structure, with the data cable 3 passing through its interior. Its outer spherical surface is precisely matched with the inner spherical surface of the serial port connector 2 terminal, which can achieve 360° rotation without dead angles. When in a narrow space or when the orientation of the connector needs to be adjusted, the universal ball 4 can rotate flexibly with the twist of the data cable 3, avoiding damage to the cable caused by forced bending. It can also adapt to different insertion conditions, such as narrow spaces, while reducing the insertion and extraction stress between the connector and the device interface, providing adaptability for different usage scenarios.

[0047] Fixed angle and guaranteed communication stability;

[0048] 1. First, insert the USB connector 1 into the device interface to complete the initial connection.

[0049] 2. Manually press the buckle 701 of the pressing mechanism 7. The buckle 701 transmits external force to the spring ring 602, causing the spring ring 602 with triple overlapping wave-shaped cross section to shrink and deform.

[0050] 3. The spring-loaded ring 602 contracts, causing multiple inserts 601 to open outwards simultaneously, separating them from the through holes of the buckle 8 and releasing the circumferential limit.

[0051] 4. Rotate the connecting cover 5 to the optimal angle where the twist of the data cable body 3 is minimal. At this point, the stress in the core wire inside the cable is released, and the signal transmission path is stable.

[0052] 5. Loosen the buckle 701. The spring ring 602 returns to its original shape due to the elasticity of the spring steel, pushing the insert 601 to re-insert into the through hole of the buckle 8. The angle is locked by the tight fit between the insert 601 and the through hole.

[0053] During this process, the wave-shaped structure of the spring-loaded ring 602 ensures continuous and stable radial pressure, keeping the insertion arc 601 in reliable contact with the retaining ring 8 and preventing angular deviation caused by vibration or slight pulling. At the same time, the rotational characteristics of the threading ball 4 reduce 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, which is especially suitable for scenarios with high requirements for communication continuity, such as industrial control and equipment debugging.

[0054] The aforementioned insert 601 only serves a positioning and fixing function, lacking a buffering and protective effect. In order to achieve anti-pull buffering protection for the end part, the following structure is designed.

[0055] The end of the serial port connector 2 is provided with a curved slope 201. The insertion arc 601 is generally arc-shaped. The outer wall of the insertion arc 601 is curved and fits against the outer side of the curved slope 201 and is limited. The outer periphery of the insertion arc 601 is provided with a fixing plate 603 that is fixed to the inner wall of the connecting cover 5. The fixing plate 603 has a through groove that constrains the insertion arc 601 to rotate around the center of the curved arc.

[0056] The insert 601 is made of elastic metal, the cross section of the spring-loaded ring 602 is an arc corresponding to that of the insert 601, and the snap fastener 701 is a ring with a notch.

[0057] Working principle: During the positioning process, the insertion arc 601, with its arc-shaped design, rotates around the center of the arc along the slot of the fixing plate 603. The notch ring structure of the snap fastener 701 matches the corresponding arc of the spring ring 602. When the snap fastener 701 is pressed, the spring ring 602 contracts under force, causing the insertion arc 601 to rotate synchronously. At this time, the outer arc of the insertion arc 601 fits against the outer side of the arc slope 201 at the end of the serial port connector 2. During rotation, it achieves insertion or separation from the buckle 8, completing the positioning operation. This rotational insertion positioning method allows the rotation center of the insertion arc 601 to disperse the force when horizontal or vertical tension is applied to it, preventing the insertion arc 601 from easily disengaging from the buckle 8 and ensuring the stability of the positioning.

[0058] When the end portion is subjected to tensile force, the insertion arc 601, being made of elastic metal, will undergo a certain degree of elastic deformation. Under the action of tension, the insertion arc 601 will produce slight expansion or contraction along its arc trajectory, absorbing part of the tensile force through its own elastic deformation, thus playing a buffering role. At the same time, the slot of the fixing plate 603 constrains the rotation range of the insertion arc 601, preventing it from being damaged due to excessive deformation. The triple-overlapping wavy cross section of the spring pressure ring 602 can also cooperate with the elastic deformation of the insertion arc 601 to further disperse and buffer the external force, reducing the impact of tensile force on the connection between the data cable body 3 and the serial port connector 2, thereby effectively protecting the end portion and reducing the risk of line damage or communication interruption caused by tensile force.

[0059] In summary, the rotary positioning of the 601 connector ensures the reliability of angle fixation, while its elastic characteristics and the cooperation of various components provide anti-pull buffer protection. The combination of these two features enhances the durability of the data cable connector and the stability of communication.

[0060] While the above method can position the insertion arc 601 and the buckle 8, the positioning operation is rather cumbersome and cannot be performed conveniently. To address this issue, the following structure is designed.

[0061] The pressing mechanism 7 also includes a fixing buckle 702 for constraining the sliding direction of the buckle 701. The end of the buckle 701 away from the spring ring 602 is connected to a constraint protrusion 703. The constraint protrusion 703 prevents excessive movement and the buckle 701 from sliding out. One side of the fixing buckle 702 is fixed to the inner wall of the connecting cover 5. A pressing post 704 is provided on one side of the fixing buckle 702. The pressing post 704 passes through the connecting cover 5 and is connected to a slide block 705.

[0062] The slide block 705 is limited to sliding with the connecting cover 5. A sliding lock buckle 706 is slidably provided on the outer side of the slide block 705. Multiple sliding lock grooves 707 adapted to the sliding lock buckle 706 are provided on the connecting cover 5. An integrated sliding sleeve 708 is connected between the outer peripheries of multiple slide blocks 705. The integrated sliding sleeve 708 has a multi-layer concave-convex ring structure.

[0063] Working principle: When it is necessary to adjust the positioning state of the insert 601 and the buckle 8, the operator pushes the integrated sliding sleeve 708 (the multi-concave-convex ring structure is easy to grip and exert force), which drives multiple sliding blocks 705 to slide along the connecting cover 5. When the sliding block 705 moves, the pressure column 704 connected to it passes through the connecting cover 5 at the same time and applies a pushing force 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 fixing 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 as the axis.

[0064] Because the snap fastener 701 is a ring with a notch and adopts a center-rotation design, it can compress the spring ring 602 within a smaller travel distance compared to a linear push structure. The rotation of the snap fastener 701 can amplify the force on the spring ring 602 through the lever principle, reducing the amount of displacement required for operation. It perfectly fits the small volume space limitation at the end of the computer data cable. After being compressed, the spring ring 602 shrinks and deforms, causing the insert 601 to rotate and disengage from the hole of the snap ring 8, releasing the positioning state.

[0065] When the rotating 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 opposite direction to reset the slide 705. The pressure post 704 releases the thrust on the constraint protrusion 703. The spring-loaded 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 moved into the corresponding sliding lock groove 707 on the connecting cover 5. The mechanical locking structure fixes the position of the slide 705, thereby locking the state of the pressure buckle 701 and the spring-loaded ring 602, ensuring that the positioning of the insert arc 601 and the buckle 8 is stable.

[0066] The multi-concave-convex ring structure of the integrated slide sleeve 708 not only improves the grip friction, but also provides feedback on the operating stroke through the concave-convex texture, making it easier for the operator to perceive the positioning state switching node. Multiple slides 705 are linked through the integrated slide sleeve 708 to ensure that all pressing mechanisms 7 operate synchronously, avoiding positioning deviation caused by uneven force on a single buckle 701, and greatly improving the ease of operation and positioning reliability.

[0067] Although the above-mentioned design provides a buffering effect against pulling, the design of the data cable body 3 does not include a redundant buffer section. Pulling it may still cause internal damage. To address this, the data cable body 3 has been redesigned.

[0068] The data cable 3 consists of a spring-loaded section 301 and a long connector section 302. The long connector section 302 has a rubber outer layer, while the spring-loaded section 301 is made of elastic latex. The spring-loaded section 301 has a wavy shape with redundant circuit segments. The internal wires of the redundant circuit segments are also wavy. This, combined with the elasticity of the latex, gives the cable a redundant amount. When pulled, the end has a buffer section. The inner wall of the connecting cover 5 is fixed to the end of the long connector section 302 near the spring-loaded section 301.

[0069] Working principle: The long connector 302, as the main body of the data cable 3, is made of rubber material with good flexibility and wear resistance, which can meet the usage requirements of conventional wiring scenarios. Its end near the elastic 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 section 301 for buffering.

[0070] The elastic section 301 is made of highly elastic latex material and has an overall wave-like shape. The redundant circuit segments inside are also designed in a wave shape. This structure gives the elastic section 301 a certain amount of stretching margin. When the data cable 3 is pulled, the external force is transmitted to the elastic section 301 through the long connector 302. The latex material will stretch and deform due to its own elasticity. The outer layer of the wave shape and the inner wave-shaped lines unfold synchronously, converting the pulling force into elastic potential energy.

[0071] During the stretching process, the redundant wave-shaped structure provides a buffer space for the line, preventing the line from directly bearing severe tension. When the tension disappears, the elastic recovery force of the latex material causes the elastic stretching section 301 to contract back to the wave shape, and the internal line also resets, ensuring the integrity of the line and the stability of signal transmission.

[0072] This design allows the elastic section 301 at the end of the data cable 3 to act as a buffer section when it is pulled. Through elastic deformation and redundant structure, it absorbs the pulling energy, greatly reducing the risk of the internal cable being pulled and damaged. Combined with the anti-pull buffering effect of the plug arc 601, it further improves the durability of the entire data cable connector.

[0073] The aforementioned data cable 3 has a buffer section, but its effectiveness is low. When subjected to external force, the cable is prone to bending. To address this issue...

[0074] The long connector 302 is fixed with a tightening sleeve 303 on its outer periphery. The tightening sleeve 303 is made of an elastic material. Multiple protrusions 304 are provided on the outer periphery of the tightening sleeve 303. The multiple protrusions 304 are arranged in a ring array with the tightening sleeve 303 as the center.

[0075] Furthermore, when used in areas with a high concentration of rodents (such as areas with abundant forests), a twisted channel is formed between adjacent convex rhombuses 304 to enhance the anti-biting effect. The twisted channel consists of an outward flare 401, a biting opening 402, and an inner air-pressure opening 403. The inner air-pressure opening 403 is in the shape of a narrow bottle. The biting opening 402 is located at the bottle mouth of the inner air-pressure opening 403 and has a narrower inward convex shape. The outward flare 401 is located outside the biting opening 402 and has a trumpet shape with a decreasing diameter from the outside to the inside.

[0076] Working principle;

[0077] I. Anti-bending constraint mechanism;

[0078] The outer twisted jacket 303 of the extended connector 302 is made of a highly elastic material (such as modified TPU). The convex diamonds 304 distributed in a ring around its periphery form a multi-directional support structure. When the data cable 3 is twisted or bent by external force, the sides of adjacent convex diamonds 304 come into contact with each other and are squeezed. The rigid contour of the convex diamonds 304 stores stress through elastic deformation, forming a mutually twisted constraint force, which prevents the jacket from bending excessively in one direction. This design allows the extended connector 302 to maintain the natural curvature of the core wire inside the cable when subjected to a bending force of ≤90°, avoiding core wire breakage or insulation layer damage caused by severe bending. Combined with the buffering effect of the elastic pull section 301, it improves the overall bending resistance performance.

[0079] II. Rodent defense mechanisms against gnawing;

[0080] In areas where rodents are active, such as forests, the twisted channels between adjacent convex rhombuses 304 form a physical repellency structure through a special morphological design;

[0081] The outward flare 401 is trumpet-shaped (the diameter decreases from the outside to the inside), and its tilt angle (optimal 30°-45°) is adapted to the biting angle of the rodent incisors, guiding the teeth to enter the groove along the slope;

[0082] When the rodent's teeth penetrate deep into the bite opening 402, the convex, narrowed spacing structure and the elastic material of the tightening outer sleeve 303 work together:

[0083] The teeth squeeze the two side walls of the biting mouth 402, causing the elastic sleeve to deform and generate a reverse clamping force, which continuously squeezes the two sides of the teeth.

[0084] The narrow bottle shape of the inner pressure port 403 further restricts the space for tooth movement. Combined with the clamping force of the biting pressure port 402, it causes discomfort (such as tooth pressure pain) when the rodent bites, thus forming a conditioned reflex of avoidance.

[0085] This design eliminates the need for chemical repellents. By combining physical structure with animal behavior, it effectively reduces the risk of rodent damage to the filament without compromising its flexibility. It is suitable for complex environments such as outdoor areas and forests.

[0086] In summary, the Tightening Jacket 303 solves the problem of data cable fragility under complex working conditions through a dual mechanism of "convex diamond twisting to prevent bending + groove physical anti-biting", thus extending its service life for outdoor use.

[0087] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
