[0020] It is easily understood that, according to the technical solution of the present application, one of ordinary skill in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary description of the technical solution of the present application, and should not be considered as the whole or as the limitation or restriction of the technical solution of the present application.

[0021] According to an embodiment of the present application, the computer cable preventing conductor deviation according to the present application is shown in FIG. 1. Figures 1 to 9 is shown.

[0022] The existing computer cable needs to be bent during use. Since the computer cable conductor 1 has a certain rigidity, which is caused by the material characteristics and cross-section design of the conductor, the stress state of the bending area is obviously unevenly distributed during the bending process. The inner conductor near the bending center is subjected to strong compression stress, while the outer conductor far from the center is subjected to continuous tensile stress. The stress difference will force the computer cable conductor 1 to deviate from the expected position inside the cable. When the computer cable conductor 1 is bent, the inner computer cable conductor 1 under compression may arch outward due to extrusion. At this time, the rigidity of the computer cable conductor 1 will extrude the outer structure, thereby affecting the stability of the whole cable. In order to solve this problem, the present application makes 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 responsible for transmitting electrical signals or power in the computer cable and is the carrier for realizing data, instruction or power transmission between the computer system and related equipment. Its performance directly affects the stability, speed and reliability of signal transmission and plays a key role in computer and automation 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 outside the cable conductor. Its core function is to isolate the conductor from the outside or different conductors to prevent current leakage, short circuit or external factors from interfering with the conductor. It is one of the key structures to ensure the safe and stable operation of the cable. The outer wall of the cable insulation layer 2 is wrapped with a cable shielding layer 3, which is a conductive layer wrapped outside 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. It is one of the key structures to ensure the quality of cable signal transmission, especially indispensable in high-frequency, weak-signal or complex electromagnetic environment. The outer wall of the cable shielding layer 3 is wrapped with a bellows isolation layer 4, which 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 structural characteristics, while considering certain flexibility and support. The outer wall of the bellows isolation layer 4 is wrapped with a cable support layer 5, which is a functional layered structure in the cable structure for enhancing the overall mechanical strength, fixing the position of internal components and providing structural stability. It is usually located in the inner layer of the cable and provides support and protection for the cable during laying, use and environmental changes through its 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, which is a protective structure wrapped in the outermost layer of the cable and directly contacts with the outside environment. Its main function is to resist external mechanical damage, chemical corrosion and environmental erosion, while fixing the internal layers of the cable structure. It is a key external protection for ensuring the overall safety and service life of the cable.The top of the corrugated pipe isolation layer 4 is fixedly connected with a brittle weak structure 7, the side of the corrugated pipe isolation layer 4 is fixedly connected with a support ring 8, the outside of the corrugated pipe isolation layer 4 is filled with a first liquid 9, and the inside of the corrugated pipe isolation layer 4 is filled with a second liquid 10.

[0023] The corrugated pipe isolation layer 4 is made of titanium alloy memory metal material, the brittle weak structure 7 is made of polystyrene material, the brittle weak structure 7 will crack in a straightened state, the first liquid 9 is made of high-activity liquid isocyanate material, the first liquid 9 has insulation, the second liquid 10 is composed of low-molecular-weight polyether polyol, triethylenediamine and azoformamide powder, the second liquid 10 has insulation, the first liquid 9 and the second liquid 10 can have cross-linking reaction when in contact, the liquid contact position is first expanded during the reaction, and the expanded liquid is solidified into a fixed type, the support ring 8 is symmetrically arranged about the vertical central axis of the corrugated pipe isolation layer 4, the junction of the support ring 8 and the corrugated pipe isolation layer 4 is arranged in an inclined manner, the computer cable conductor 1 is made of copper wire material, the computer cable conductor 1 is composed of multiple strands of twisted wires, the cable insulation layer 2 is made of polyvinyl chloride material, the cable insulation layer 2 is used to prevent short circuit and signal leakage, the cable shielding layer 3 is a woven net-shaped tinned copper wire, the cable shielding layer 3 is used to block external electromagnetic interference and electromagnetic radiation of the cable internal signal, the cable support layer 5 is made of stainless steel material, and the cable sheath layer 6 is made of chloroprene rubber material.

[0024] The computer cable is composed of a computer cable conductor 1, a cable insulation layer 2, a cable shielding layer 3, a corrugated pipe isolation layer 4, a cable support layer 5 and a cable sheath layer 6, wherein the corrugated pipe isolation layer 4 comprises a brittle weak structure 7, a support ring 8, a first liquid 9 and a second liquid 10, the computer cable conductor 1 made of copper wire material is composed of multiple strands of fine copper wires through regular twisting, which breaks the rigid restriction of a single thick copper wire, when the cable needs to be bent, twisted or passed through an obstacle, each strand of copper wire can disperse stress through a small relative displacement, avoiding local stress concentration, the polyvinyl chloride material itself has a very high volume resistivity, so that the cable insulation layer 2 can effectively prevent current leakage, ensuring that the power or signal in the conductor is transmitted along the predetermined path, avoiding safety hazards such as short circuit and electric shock caused by poor insulation, the cable shielding layer 3 is a woven net-shaped tinned copper wire, the conductivity of the tinned copper wire is close to that of pure copper, and after being woven into a net shape, a continuous conductive barrier is formed, which can block interference through reflection and absorption, the cable support layer 5 is made of stainless steel material, 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, and the cable sheath layer 6 is made of chloroprene rubber material, which has high tensile strength, tear strength and wear resistance, and can provide a solid outer armor for the cable.

[0025] When the computer cable is in use, the area that is not bent, under the action of the bellows isolation layer 4, the bellows 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, at this time the inner side of the bellows isolation layer 4 is stacked together, providing stable support force for the inner side of the computer cable conductor 1, the outer side of the bellows isolation layer 4 is in a relaxed state, causing the bellows isolation layer 4 to tend to flatten, at this time the support force of the bellows isolation layer 4 on the outer side of the computer cable conductor 1 disappears, at the same time, under the action of extrusion, the first liquid 9 and the second liquid 10 are transferred to the outer side, the amount of the first liquid 9 and the second liquid 10 accumulated on the outer side is greater than that on the inner side, at this time the first liquid 9 and the second liquid 10 provide a certain support force for the outer side of the computer cable conductor 1, at the same time, due to the flattening of the bellows isolation layer 4, the brittle weak structure 7 cracks under the action of the pulling force, at this time the first liquid 9 and the second liquid 10 come into contact in the cracking area, when the first liquid 9 and the second liquid 10 react, they first fill the outer side area, and then completely solidify into a dense-pore solid, the generated solid supports the outer side of the computer cable conductor 1, so that the computer cable conductor 1 is in the center position of the computer cable body.

[0026] The bellows isolation layer 4 is provided, when the computer cable is bent, the outer bellows isolation layer 4 begins to expand, at this time the first liquid 9 and the second liquid 10 move to the outer side under the action of pressure, providing auxiliary support for the cable conductor, when the bending angle is too large, the outer bellows isolation layer 4 tends to completely expand, at this time the support force of the outer bellows isolation layer 4 on the cable conductor disappears, when the bellows isolation layer 4 expands, the brittle weak structure 7 cracks, at this time the first liquid 9 and the second liquid 10 inside and outside the bellows isolation layer 4 come into contact, the first liquid 9 and the second liquid 10 react, first expanding during the reaction process, and then solidifying after expansion, at this time the expanded solid supports and fixes the cable conductor, which facilitates avoiding the position of the cable conductor from deviating.

[0027] When the cable is normally bent, the outer corrugated tube isolation layer 4 unfolds, driving the first liquid 9 and the second liquid 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 received by the conductor during bending, reduce the internal structure stretching or extrusion caused by bending, protect the integrity of the conductor and the insulation layer, and the design of the fragile weak structure 7 is the key trigger point. Only when the corrugated tube is fully unfolded, the weak structure will crack, ensuring that the first liquid 9 and the second liquid 10 only react when necessary, avoiding false triggering. This starting mechanism improves the accuracy of protection, reduces unnecessary material consumption or functional interference. After the two liquids come into contact, they first expand and then solidify. The expansion process can fill the gap around the conductor, and after solidification, a rigid support structure is formed, which tightly and stably fixes the conductor. This fixing method can effectively prevent the conductor from shifting due to excessive bending, vibration or external force, prevent relative friction or poor contact between the conductor and the insulation layer and the shielding layer, and ensure the stability of the electrical performance of the cable. From dynamic buffering during normal bending to emergency fixation during excessive bending, the entire process forms a stepped protection, allowing the cable to be used flexibly within a reasonable range, and actively intervening when the safety limit is exceeded. Through the combination of physical support and chemical fixation, internal damage caused by improper bending is reduced, thereby prolonging the service life of the cable and improving the safety of use.

[0028] The technical scope of the present application is not limited to the above description. Those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should be within the scope of protection of the present application.
