[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figures 1 to 9 Shown.

[0021] Existing computer cables often need to be bent during use. Since the computer cable conductor 1 has a certain degree of rigidity, this rigidity is derived from the material properties and cross-sectional design of the conductor. As a result, during the bending process, the stress state in the bending area presents a significant uneven distribution. The inner conductor close to the bending center is subjected to strong compressive stress, while the outer conductor away from the center is subjected to continuous tensile stress. This stress difference forces the computer cable conductor 1 to undergo unexpected positional displacement inside the cable. When the computer cable conductor 1 is bent, the inner compressed computer cable conductor 1 may be extruded and arch outward. At this time, the rigidity of the computer cable conductor 1 will squeeze the outer structure, thereby affecting the overall stability of the cable. To solve this problem, the present invention has made the following design on the computer cable for preventing conductor deviation: A computer cable for preventing conductor deviation, comprising: a computer cable conductor 1, which is the core conductive component in the computer cable responsible for transmitting electrical signals or electrical energy. It is the carrier for realizing data, instruction or power transmission between computer systems and related equipment. Its performance directly affects the stability, speed and reliability of signal transmission, and plays a key role in computers and automatic control systems. The outer wall of the computer cable conductor 1 is wrapped with a cable insulation layer 2, which is a non-conductive material layer wrapped around the outside of the cable conductor. Its core function is to isolate the conductor from the outside or different conductors, and prevent current leakage, short circuit or external factors from affecting the conductor. The outer wall of the cable insulation layer 2 is wrapped with a cable shielding layer 3. The cable shielding layer 3 is a conductive layer wrapped around the outside of the cable insulation layer 2. Its main function is to isolate electromagnetic interference and radio frequency interference, while reducing the interference of the cable's own signal to the outside world. It is one of the key structures to ensure the quality of cable signal transmission, especially in high-frequency, weak signal or complex electromagnetic environments. The outer wall of the cable shielding layer 3 is wrapped with a corrugated tube isolation layer 4. The corrugated tube isolation layer 4 is a tubular isolation component with corrugated folds in the cable structure. It is usually made of metal, plastic or composite materials. Its main function is to achieve physical isolation, buffer protection, dynamic adaptation and other functions through its own structural characteristics, while taking into account certain The outer wall of the corrugated tube isolation layer 4 is wrapped with a cable support layer 5. The cable support layer is a functional layered structure in the cable structure used to enhance the overall mechanical strength, fix the position of internal components and provide structural stability. It is usually located in the inner layer of the cable. It provides support and protection for the cable during laying, use and environmental changes through its own mechanical properties. It is an important part of ensuring the integrity of the cable structure. The outer wall of the cable support layer 5 is wrapped with a cable sheath layer 6. The cable sheath layer 6 is a protective structure wrapped around the outermost layer of the cable, which is in direct contact with the external environment. Its main function is to resist external mechanical damage, chemical corrosion, and environmental erosion. At the same time, it fixes the internal structure of the cable and is a key outer layer protection to ensure the overall safety and service life of the cable.The top of the bellows isolation layer 4 is fixedly connected to a brittle weak structure 7, the side of the bellows isolation layer 4 is fixedly connected to a support ring 8, the outside of the bellows isolation layer 4 is filled with a first liquid 9, and the inside of the bellows isolation layer 4 is filled with a second liquid 10.

[0022] The bellows isolation layer 4 is made of titanium alloy memory metal, the brittle weak structure 7 is made of polystyrene, and the brittle weak structure 7 will crack when straightened. Liquid No. 1 9 is made of highly active liquid isocyanate. Liquid No. 1 9 has insulating properties. Liquid No. 2 10 is composed of low molecular weight polyether polyol, triethylenediamine and azodicarbonamide powder. Liquid No. 2 10 has insulating properties. Liquid No. 1 9 and Liquid No. 2 10 can undergo a cross-linking reaction when in contact. During the reaction, the liquid contact position expands first, and then solidifies and fixes after expansion. The support ring 8 is about the bellows. The vertical central axis of the isolation layer 4 is symmetrically arranged, and the connection between the support ring 8 and the corrugated tube isolation layer 4 is inclined. The computer cable conductor 1 is made of copper wire, and the computer cable conductor 1 is composed of multiple strands. The cable insulation layer 2 is made of polyvinyl chloride. The cable insulation layer 2 is used to prevent short circuits and signal leakage. The cable shielding layer 3 is a tinned copper wire woven into a mesh. The cable shielding layer 3 is used to block external electromagnetic interference and electromagnetic radiation of internal signals of the cable. The cable support layer 5 is made of stainless steel, and the cable sheath layer 6 is made of chloroprene rubber.

[0023] The computer cable consists of a computer cable conductor 1, a cable insulation layer 2, a cable shielding layer 3, a corrugated tube isolation layer 4, a cable support layer 5, and a cable sheath layer 6. The corrugated tube isolation layer 4 includes a brittle weak structure 7, a support ring 8, a No. 1 liquid 9, and a No. 2 liquid 10. The copper wire computer cable conductor 1 is made of multiple strands of fine copper wire twisted in a regular pattern, breaking the rigidity limitation of a single strand of thick copper wire. When the cable needs to bend, twist, or bypass an obstacle, each strand of copper wire can disperse stress through a small relative displacement to avoid local force concentration. The polyvinyl chloride material itself has an extremely high volume resistivity, which enables the cable insulation layer 2 to effectively block current. Leakage, ensure that the power or signal in the conductor is transmitted along the predetermined path, and avoid safety hazards such as short circuit and electric shock caused by poor insulation. The cable shielding layer 3 adopts tinned copper wire woven into a mesh. The conductivity of tinned copper wire is close to that of pure copper. After being woven into a mesh, it forms a continuous conductive barrier, which can block interference by reflection and absorption. The cable support layer 5 is made of stainless steel. The stainless steel support layer can effectively resist deformation, avoid damage to the internal conductor and insulation layer due to extrusion, and ensure the integrity of the cable structure. The cable sheath layer 6 is made of chloroprene rubber. Neoprene has high tensile strength, tear strength and wear resistance, and can provide a solid outer armor for the cable.

[0024] When the computer cable is in use, in the unbent area, under the action of the corrugated tube isolation layer 4, the corrugated tube isolation layer 4 supports the computer cable conductor 1, so that the computer cable conductor 1 is always in the center position. When the computer cable is excessively bent, the inner sides of the corrugated tube isolation layer 4 are stacked together to provide stable support for the inner side of the computer cable conductor 1. The outer side of the corrugated tube isolation layer 4 tends to be flat due to the stretching state. At this time, the support force of the corrugated tube isolation layer 4 on the outer side of the computer cable conductor 1 disappears. At the same time, under the action of squeezing, the No. 1 liquid 9 and the No. 2 liquid 10 are transferred to the outside. The amount of liquid No. 1 9 and liquid No. 2 10 accumulated on the outside is greater than that on the inside. At this time, liquid No. 1 9 and liquid No. 2 10 provide a certain support force for the outside of the computer cable conductor 1. At the same time, since the corrugated tube isolation layer 4 tends to be flat, the brittle and weak structure 7 cracks under the action of the pulling force. At this time, liquid No. 1 9 and liquid No. 2 10 contact in the cracked area. When liquid No. 1 9 and liquid No. 2 10 react, they first fill the outer area. After filling, they are completely solidified into a dense closed-cell solid. The generated solid supports the outside of the computer cable conductor 1, so that the computer cable conductor 1 is in the center position of the computer cable body.

[0025] A bellows isolation layer 4 is provided. When the computer cable is bent, the outer bellows isolation layer 4 begins to unfold. At this time, liquid No. 1 9 and liquid No. 2 10 move outward under the action of pressure to provide auxiliary support for the cable conductor. When the bending angle is too large, the outer bellows isolation layer 4 tends to unfold completely. At this time, the supporting force of the outer bellows isolation layer 4 on the cable conductor disappears. When the bellows isolation layer 4 unfolds, the brittle and weak structure 7 cracks. At this time, liquid No. 1 9 and liquid No. 2 10 inside and outside the bellows isolation layer 4 are in contact, and liquid No. 1 9 and liquid No. 2 10 react. During the reaction process, they first expand and then solidify into a fixed shape. At this time, the expanded fixation supports and fixes the cable conductor to avoid the position of the cable conductor from being offset.

[0026] When the cable is bent normally, the outer bellows isolation layer 4 expands, driving liquid No. 1 9 and liquid No. 2 10 to move outward, providing real-time auxiliary support for the cable conductor. This support is dynamically adjusted with the bending action, which can buffer the stress on the conductor when bending, reduce the stretching or squeezing of the internal structure caused by bending, and protect the integrity of the conductor and insulation layer. The design of the brittle weak structure 7 is the key trigger point. The weak structure will only crack when the bellows is fully expanded, ensuring that liquid No. 1 9 and liquid No. 2 10 will only contact and react when necessary to avoid false triggering. This starting mechanism improves the accuracy of protection and reduces unnecessary material consumption or functional interference. After the two liquids come into contact, they first expand and then solidify into a fixed type The expansion process can fill the gap around the conductor, and after solidification, it forms a rigid support structure, which can achieve tight and stable fixation of the conductor. This fixation method can effectively avoid the conductor position displacement caused by excessive bending, vibration or external force pulling, and prevent relative friction or poor contact between the conductor and the insulation layer and shielding layer, thereby ensuring the stability of the cable's electrical performance. From dynamic buffering during normal bending to emergency fixation during excessive bending, the whole process forms a stepped protection, which allows the cable to be used flexibly within a reasonable range, and can actively intervene when it exceeds the safety limit. Through the combination of physical support and chemical fixation, the internal damage caused by improper bending is reduced, thereby extending the service life of the cable and improving the safety of use.

[0027] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
