[0002] With the continuous advancement of communication technology and the increasing expansion of application scenarios, traditional indoor communication components can no longer meet the market's demand for high-performance communication solutions. Especially in outdoor environments, such as grasslands, deserts, forests, and plateaus, environmental conditions place higher demands on communication equipment. These environments may include extreme temperatures, strong sunlight, rain, vibration, and electromagnetic interference, all of which can have a serious impact on the performance of communication components. Therefore, the development of anti-interference communication components suitable for these harsh environments has become an urgent need in the market.
[0003] Existing communication cable technologies often face the following challenges in these environments:
[0004] Environmental interference: Traditional cables often lack effective anti-interference design and are easily affected by electromagnetic interference (EMI) and radio frequency interference (RFI), resulting in unstable or lost signal transmission.
[0005] Insufficient weather resistance: Conventional outer sheath materials perform poorly under extreme weather conditions (such as high temperature, low temperature, and humidity changes) and are prone to aging or losing their protective functions, thus affecting the service life and stability of the cable.
[0006] Limited ability to resist mechanical stress: Vibration and mechanical shock in the field environment pose a challenge to the structural stability of the cable, and conventional cable structures may have problems in dealing with these mechanical stresses.
[0007] Connection reliability: Traditional connectors lack connection stability and sealing when facing complex environmental conditions, resulting in poor contact and signal loss. Summary of the invention

[0016] The outer sheath is a thermoplastic polyurethane outer sheath;
[0017] The anti-interference connector is provided with a plug-in cavity, the inner wall of the plug-in cavity is provided with a conductive ring and a waterproof sealing ring, and the anti-interference connector is provided with a circle of annular locking grooves on the periphery of the plug-in cavity;
[0018] The anti-interference connector is provided with a plug connector, the plug connector is provided with conductive contacts at intervals, and the anti-interference connector is provided with a locking tongue;
[0019] The plug connector is inserted into the plug cavity, the conductive contact contacts the conductive ring, the waterproof sealing ring is tightly attached to the plug connector, and the lock tongue is inserted into the annular lock groove. When the plug connector is rotated, the conductive contact always contacts the conductive ring, and the lock tongue is always located in the annular lock groove and slides along the annular lock groove.
[0020] Four pairs of shielded twisted cables with inconsistent pitches can effectively reduce near-end crosstalk (NEXT) and far-end crosstalk (FEXT), thereby improving signal transmission quality and stability.
[0021] The multiple shielding structure of the first wrapped shielding sleeve and the second wrapped shielding sleeve can effectively shield external electromagnetic interference, improve the anti-interference ability of the cable, and ensure the integrity and reliability of the signal.

[0027] The shielding sleeve wrapped with aluminum-polyethylene composite tape has good shielding performance and durability, which further enhances the anti-interference ability of the cable.
[0028] The purpose of the present invention can also be solved by the following technical measures:
[0029] Furthermore, the surface of the outer sheath is covered with a nano waterproof coating.
[0030] Covering the outer sheath surface with a nano-waterproof coating can effectively prevent moisture penetration, improve the waterproof performance of the cable, and ensure normal use in humid or watery environments.
[0031] The nano waterproof coating has excellent corrosion resistance and aging resistance, which can effectively prevent the erosion of the outer sheath by moisture, chemicals and ultraviolet rays, and extend the service life of the cable.
[0032] The nano waterproof coating has excellent self-cleaning function, which can reduce the adhesion of dust, dirt, etc., keep the cable surface clean, and improve the adaptability of the cable in various harsh environments.
[0033] Due to the waterproof, anti-fouling and corrosion-resistant properties of the nano waterproof coating, the cable is less susceptible to environmental factors during use, reducing the frequency of maintenance and cleaning, thereby reducing maintenance costs.
[0034] Nano waterproof coatings are usually ultra-thin coatings that do not significantly increase the thickness and weight of the cable, while maintaining the flexibility and operability of the cable for easy installation and wiring.
[0035] The nano waterproof coating can effectively isolate moisture, prevent the risk of short circuit or electric shock caused by moisture in the cable, and improve the safety of cable use.
[0036] Further, the outer sheath comprises an intelligent temperature control material, and the intelligent temperature control material comprises a phase change material for absorbing or releasing a large amount of latent heat to maintain temperature stability;
[0037] Thermochromic materials that change color as temperature changes to monitor and identify the temperature condition of the cable in real time;

[0043] Nano thermal conductive materials, by improving the thermal conductivity of cables, can quickly dissipate the heat generated by the cables during operation, prevent the cables from overheating, ensure the stable operation of the cables under high load or high temperature environments, and extend the service life of the cables.
[0044] Thermal expansion materials, when the cable is heated, these materials will expand, fill the gaps caused by thermal expansion, maintain the integrity of the cable's internal structure, prevent cable breakage or damage caused by thermal expansion and contraction, and further improve the reliability of the cable.
[0045] Intelligent temperature control materials enable the cable to adapt to extreme temperature environments. Whether it is high or low temperature, it can maintain stable performance, ensure the continuity and stability of communication, and meet the use requirements in complex outdoor environments.
[0046] Through comprehensive protection measures such as temperature stability, real-time monitoring, rapid heat dissipation and gap filling, intelligent temperature control materials greatly improve the safety of cables and reduce failures and safety hazards caused by temperature-related problems.
[0047] Real-time temperature monitoring and efficient heat dissipation can help prevent temperature-induced failures and reduce maintenance work caused by cable overheating or other temperature-related problems, thereby reducing maintenance costs and improving the overall economic benefits of the cable.
[0048] Furthermore, the phase change material is paraffin, the thermochromic material is vanadium oxide, the nano thermal conductive material is graphene, and the thermal expansion material is expanded graphite.
[0049] Paraffin (phase change material), paraffin maintains the temperature stability of the cable when the temperature changes by absorbing or releasing a large amount of latent heat, preventing the cable performance from degrading due to temperature fluctuations, thereby ensuring the stable transmission of communication signals.
[0050] Vanadium oxide (thermochromic material), vanadium oxide changes color as the temperature changes, providing an intuitive temperature monitoring method, allowing maintenance personnel to quickly identify the temperature condition of the cable, perform preventive maintenance in a timely manner, avoid cable damage caused by overheating, and improve the safety of cable use.
[0051] Graphene (nano thermal conductive material), graphene has extremely high thermal conductivity. After its nanosheets are evenly dispersed in the outer sheath, it can quickly dissipate the heat generated by the cable during operation, prevent the cable from overheating, ensure the stable operation of the cable under high load or high temperature environment, and extend the service life of the cable.
[0052] Filling the thermal expansion gap:
[0053] Expanded graphite (thermal expansion material), expanded graphite expands when heated, filling the gaps caused by thermal expansion and contraction, maintaining the integrity of the internal structure of the cable, preventing the cable from breaking or being damaged due to thermal expansion and contraction, and improving the reliability and service life of the cable.
[0054] The combination of paraffin, vanadium oxide, graphene and expanded graphite enables the cable to adapt to extreme temperature environments. Whether it is high or low temperature, it can maintain stable performance, ensure the continuity and stability of communication, and meet the use requirements in complex outdoor environments.
[0055] Comprehensive protection measures such as temperature stability, real-time monitoring, rapid heat dissipation and gap filling have greatly improved the safety of the cable, reduced failures and safety hazards caused by temperature-related problems, and ensured the long-term and stable operation of the cable.
[0056] Real-time temperature monitoring and efficient heat dissipation help prevent temperature-induced failures and reduce maintenance work caused by cable overheating or other temperature-related problems, thereby reducing maintenance costs and improving the overall economic benefits of the cable.
[0057] Through temperature control and heat dissipation management, the cable can maintain good transmission performance under various temperature conditions, avoid signal attenuation and interference problems caused by temperature changes, and ensure stable and reliable communication quality.
[0058] Furthermore, the specific steps of integrating the intelligent temperature control material into the outer sheath include:
[0059] Step 1: Prepare corresponding intelligent temperature control materials, such as microencapsulated paraffin, vanadium oxide pigments, graphene nanosheets and expanded graphite powder.
[0060] Step 2: Use a high shear mixer or twin-screw extruder to evenly mix the above intelligent temperature control materials into the polymer matrix of the outer sheath material. Ensure that each material is evenly distributed to play its respective function.
[0061] Step 3: Extruding the mixed outer sheath material to form the outer sheath. During this process, the processing temperature and pressure are controlled to ensure uniform distribution and physical properties of the material.
[0062] The molded outer sheath is cooled and solidified to ensure its mechanical strength and the stability of the intelligent temperature control function.
[0063] Step 4: Perform performance testing on the manufactured outer sheath to ensure its stability and anti-interference ability in extreme temperature environments, including thermochromic response, thermal conductivity and expansion characteristics.
[0064] The paraffin is encapsulated in microcapsules through microencapsulation technology, and then these microcapsules are evenly dispersed in the outer sheath material. Microencapsulation technology can effectively encapsulate the paraffin to prevent it from leaking during use, while ensuring that the paraffin can perform phase change functions when the temperature changes, absorbing or releasing heat.
[0065] Vanadium oxide is added to the outer sheath material as a thermochromic pigment. During the manufacturing process of the outer sheath material, the vanadium oxide pigment is uniformly mixed into the polymer matrix, allowing it to change color as the temperature changes, thereby providing an intuitive temperature monitoring function.
[0066] The graphene nanosheets are evenly dispersed in the polymer matrix of the outer sheath material by solution mixing or melt blending. Graphene has extremely high thermal conductivity. After being evenly dispersed in the outer sheath material, it can significantly improve the overall thermal conductivity of the cable and help to quickly dissipate heat.
[0067] Expanded graphite is uniformly mixed into the outer sheath material in powder or granular form. Expanded graphite expands when heated, filling the voids created by thermal expansion, protecting the internal structure of the cable and maintaining its physical integrity and stability.
[0068] The paraffin wax is evenly dispersed in the outer sheath material through microencapsulation technology, which enables the cable to effectively absorb or release latent heat and maintain temperature stability. Even under extreme temperature conditions, the cable can operate stably and prevent performance degradation caused by temperature fluctuations.
[0069] Vanadium oxide pigments change color when the temperature changes, providing an intuitive means of temperature monitoring. Maintenance personnel can quickly identify the temperature condition of the cable and perform preventive maintenance in a timely manner to avoid cable damage caused by overheating.
[0070] Graphene nanosheets significantly improve the heat dissipation performance of the cable by increasing the thermal conductivity of the outer sheath material. This allows the cable to dissipate heat quickly under high load or high temperature environments, preventing the cable from overheating and extending its service life.
[0071] Expanded graphite expands when heated, filling the gaps caused by thermal expansion and contraction, maintaining the integrity of the cable's internal structure. This thermal expansion material effectively prevents cable breakage or damage caused by temperature changes, enhancing the reliability of the cable.
[0072] By introducing a variety of intelligent temperature control materials, the outer sheath can provide comprehensive temperature control and protection functions. In extreme environments, the cable's temperature stability, real-time monitoring capabilities, heat dissipation performance and structural integrity are significantly improved.
[0073] Comprehensive protection measures reduce cable failures caused by temperature changes, improve cable safety and service life. Real-time monitoring functions help prevent potential problems and reduce maintenance workload and costs.
[0074] Through a high shear mixer or twin-screw extruder, the intelligent temperature control material is evenly dispersed in the outer sheath material to ensure that the function of each material can be fully utilized. The molding and post-processing process ensures the mechanical strength of the outer sheath and the stability of the intelligent temperature control function.
[0075] Strict performance testing ensures the stability and anti-interference ability of the finished outer sheath in extreme temperature environments. Testing includes thermochromic response, thermal conductivity and expansion characteristics to ensure that the overall performance of the cable meets the expected standards.
[0076] Furthermore, the anti-interference connector is integrated with a signal amplifier for enhancing signal transmission stability and anti-interference capability, and an anti-static coating for enhancing signal transmission stability and anti-interference capability is added to the housing of the anti-interference connector.
[0077] The integrated signal amplifier can effectively increase the signal strength and reduce the signal attenuation during transmission. This is especially important in long-distance transmission or weak signal environments to ensure communication quality and reliability.
[0078] The signal amplifier not only enhances the signal strength, but also improves the anti-interference ability and reduces the impact of external electromagnetic interference on signal transmission. This is very critical for applications in complex electromagnetic environments, ensuring the clarity and stability of the signal.
[0079] Antistatic coating can effectively prevent static electricity accumulation and reduce the damage of electrostatic discharge to equipment. Electrostatic discharge may cause signal transmission interruption or equipment damage. Antistatic coating improves the safety and reliability of equipment.
[0080] Antistatic coating not only prevents static electricity accumulation, but also has certain wear resistance and corrosion resistance, extending the service life of the equipment. For equipment applications in field environments, the protective effect of the coating is particularly important.
[0081] Through the role of signal amplifier, signal loss due to insufficient signal strength is reduced, and the reliability of transmission is improved. This is particularly evident in harsh environments or long-distance transmission, ensuring complete data transmission.
[0082] The design of integrated signal amplifier reduces the need for external devices, simplifies system design and wiring. The integrated design also reduces the number of connection points between devices and reduces the failure rate.
[0083] The combination of antistatic coating and signal amplifier enables the device to maintain good performance in various extreme environments (such as high humidity, high static electricity areas, etc.). This enhances the environmental adaptability of the device and ensures stability in different application scenarios.
[0084] The improvement of signal transmission stability and anti-interference ability significantly improves the user experience. Whether in data transmission or communication applications, more stable and high-quality signals can be obtained, reducing the risk of communication failures and data loss.
[0085] By improving the durability and reliability of equipment, the need for maintenance due to equipment failure or signal transmission problems is reduced, thereby reducing maintenance costs and time.
[0086] Further, the entrance width of the annular lock groove is smaller than the width of the annular lock groove, the lock tongue is a T-shaped lock tongue, the transverse length of the T-shaped lock tongue is greater than the entrance width of the annular lock groove, the transverse width of the T-shaped lock tongue is smaller than the entrance width of the annular lock groove, and the vertical width of the T-shaped lock tongue is smaller than the entrance width;
[0087] The user overcomes the torque of the communication cable and rotates the T-shaped lock tongue, so that the transverse portion of the T-shaped lock tongue adjusts its position, so that the transverse portion of the T-shaped lock tongue is aligned with the entrance of the annular lock groove, and the transverse portion of the T-shaped lock tongue passes through the entrance of the annular lock groove and enters the annular lock groove;
[0088] When the user loosens the T-shaped lock tongue, the torque of the communication cable drives the T-shaped lock tongue to return to its original position, causing the lateral portion of the T-shaped lock tongue to adjust its position so that the lateral portion and the entrance of the annular lock groove are misaligned, and the T-shaped lock tongue cannot escape from the annular lock groove.
[0089] The design of the T-shaped locking tongue and the annular locking groove provides a stable mechanical lock, preventing the connector from loosening due to external force during use, thereby improving the reliability of the connection.
[0090] The user only needs to rotate the T-shaped lock tongue and overcome the torque of the communication cable to complete the locking or unlocking operation. It is easy to operate and is especially suitable for rapid installation and disassembly in complex outdoor environments.
[0091] Since the transverse portion of the T-shaped lock tongue is misaligned with the entrance of the annular lock groove after locking, it is ensured that the T-shaped lock tongue cannot be separated from the annular lock groove in a non-rotating state, effectively preventing accidental loosening.
[0092] The torque of the communication cable is used to automatically restore the T-shaped locking tongue to the locked position, forming a self-locking function, reducing the possibility of human error and further ensuring the firmness of the connection.
[0093] Stable mechanical connections can reduce signal transmission fluctuations caused by unstable connections, thereby enhancing the anti-interference ability of the communication system and ensuring signal continuity and stability.
[0094] The design fully considers the vibration and impact that may occur in the field environment. The connector's stability and shock resistance are ensured through reliable mechanical locking to adapt to various harsh environments.
[0095] The locking structure avoids poor contact caused by loosening of the connector during use, reduces the impact of external interference on communication signals, and improves the overall communication quality.
[0096] Furthermore, the outer surface of the shielded twisted wire is coated with a wear-resistant coating which enhances the durability and resistance to mechanical damage of the cable.
[0097] The wear-resistant coating can significantly enhance the wear resistance of shielded stranded wires, reduce surface damage caused by friction and scratches, and thus extend the service life of the cable.
[0098] The wear-resistant coating provides an additional layer of physical protection, effectively resisting external mechanical impact, indentation and abrasion, protecting the integrity of the internal strands and shielding layers.
[0099] The protective effect of the wear-resistant coating reduces the probability of cable damage in harsh environments, thereby reducing the frequency of cable maintenance and replacement, saving maintenance costs and time.
[0100] The wear-resistant coating can not only resist mechanical damage, but also provide a certain degree of waterproof, dustproof and corrosion-resistant functions, further enhancing the cable's adaptability in harsh outdoor environments.
[0101] The wear-resistant coating protects the stranded wires from direct impact from the external environment, ensuring that the cable maintains stable electrical performance and signal transmission quality throughout its entire life cycle.
[0102] The wear-resistant coating of the shielded twisted wire reduces the shielding layer rupture or poor contact caused by wear and damage, thereby reducing signal interference and improving the stability and anti-interference ability of signal transmission.
[0103] The wear-resistant coating provides additional mechanical strength, making the cable stronger as a whole, reducing structural damage caused by external stress and impact, and ensuring the reliability of the cable under various complex conditions.
[0104] The wear-resistant coating can effectively reduce the wear and fatigue of the cable during frequent use and bending, maintain the flexibility and durability of the cable, and adapt to various dynamic use environments.
[0105] Furthermore, an insulating layer is provided between the first twisted wire core and the second twisted wire core to prevent mutual interference.
[0106] The insulating layer effectively prevents electromagnetic interference and signal crosstalk between the first twisted wire core and the second twisted wire core, thereby ensuring the purity and stability of the signal and improving the communication quality.
[0107] The insulating layer reduces the capacitive coupling effect between the twisted wire cores, reduces signal attenuation, and increases the distance and efficiency of signal transmission.
[0108] The insulating layer can isolate the electromagnetic interference between the twisted wire cores, so that the cable can still maintain high-performance anti-interference capabilities in complex electromagnetic environments and ensure signal integrity.
[0109] The insulating barrier protects the stranded wire cores from mutual interference, reduces signal distortion and transmission errors caused by interference, and improves the overall reliability and stability of the cable.
[0110] The presence of the insulating layer reduces signal reflection and refraction, reduces signal distortion, and ensures that the signal can be accurately transmitted to the terminal device.
[0111] The insulating layer not only prevents interference from the internal twisted wire core, but also shields external electromagnetic interference, thereby improving the overall anti-electromagnetic interference capability of the cable.
[0112] The insulating barrier protects the stranded wire cores from mutual friction and damage, reducing cable failures caused by internal interference and damage, and extending the service life of the cable.
[0113] The insulating layer effectively reduces interference and attenuation during signal transmission, improves data transmission speed, and ensures the realization of high-speed data communication.
[0114] The insulating layer reduces the bit error rate caused by signal interference, ensuring the accuracy and reliability of data transmission, especially in high-frequency transmission environments.
[0115] Furthermore, the outer surface of the third wrapped shielding sleeve is coated with a conductive polymer layer for improving the shielding effect.
[0116] The conductive polymer layer provides additional electromagnetic shielding, further reducing the impact of external electromagnetic interference on the signal transmission inside the cable and improving the overall anti-interference performance.
[0117] The conductive polymer layer reduces signal distortion and attenuation caused by electromagnetic interference, ensuring the clarity and stability of signal transmission and improving communication quality.
[0118] The conductive polymer layer forms a continuous conductive barrier outside the third wrapped shielding sleeve, which enhances the cable's anti-electromagnetic interference capability and enables it to maintain high performance in a complex electromagnetic environment.
[0119] The conductive polymer layer reduces signal attenuation and increases transmission efficiency and distance by reducing electromagnetic interference inside and outside the cable.
[0120] The conductive polymer layer not only has good conductivity, but also has certain wear resistance and protective properties, which increases the durability of the cable and prolongs its service life.
[0121] The conductive polymer layer is more flexible than traditional metal shielding and does not significantly increase the rigidity of the cable, maintaining the cable's flexibility and ease of installation.
[0122] Conductive polymer materials may be lighter and cheaper than traditional metal shielding materials, reducing the overall manufacturing cost of the cable.
[0123] The conductive polymer layer is relatively light, reducing the overall weight of the cable and improving the portability and installation convenience of the cable.
[0124] Conductive polymer materials may have better environmental protection and safety performance, and reduce environmental pollution and harm to the human body compared to traditional metal materials.
[0125] The conductive polymer layer has a certain corrosion resistance, which can maintain the integrity and function of the cable in harsh environments and improve the environmental adaptability of the cable.
[0126] The beneficial effects of the present invention are as follows:
[0127] The present invention adopts a design of four pairs of shielded twisted wires with inconsistent pitches, which can effectively reduce near-end crosstalk (NEXT) and far-end crosstalk (FEXT), thereby improving the transmission quality and stability of signals.

[0130] The invention discloses a thermoplastic polyurethane outer sheath, wherein the TPU material has excellent mechanical properties, wear resistance and weather resistance, and can protect the service life of the cable in various harsh environments.
[0131] The present invention adopts the design of the conductive ring and the waterproof sealing ring in the plug-in cavity to ensure the reliability of electrical connection and the waterproof and dustproof functions during plug-in.
[0132] The design of the annular locking groove and the locking tongue of the present invention enables the plug connector to be locked by rotating after being inserted into the plug cavity, thereby ensuring stable contact between the conductive contact and the conductive ring, while providing waterproof sealing protection and improving the reliability and durability of the connection.
[0133] The present invention adopts tinned copper wire as the stranded wire core, which has excellent electrical conductivity and oxidation resistance, and further improves the quality and stability of signal transmission.
[0134] The invention uses an aluminum-polyethylene composite tape wrapped around a shielding sleeve, which has good shielding performance and durability, and further enhances the anti-interference ability of the cable.
[0135] The present invention significantly enhances the waterproof, anti-fouling, corrosion-resistant and aging-resistant properties of the cable by covering the surface of the outer sheath with a nano-waterproof coating, prolongs the service life, improves the environmental adaptability and safety, and reduces the maintenance cost, thereby meeting the demand for high-performance anti-interference communication cables in field environments.
