[0002] With the rapid development of modern information technology, computer cables, as the key carrier of information transmission, are widely used in various fields. From daily office equipment to industrial automation systems, from financial data centers to complex industrial production environments, computer cables bear the heavy responsibility of efficient and stable transmission of data and signals.

[0003] With the widespread application of computer electronic technology in power generation, metallurgy, petrochemical and other industrial and mining enterprises, the use of signal transmission and detection instruments such as distributed control systems, electronic computer systems, and automation systems is becoming more and more common, and people are paying more and more attention to the signal shielding, heat dissipation, tensile strength and other properties of computer cables.

[0004] Existing computer cables are extremely unstable during signal transmission, and signal crosstalk occurs frequently, which causes signals between different lines to interfere with each other, reducing the accuracy and reliability of data transmission. Due to poor heat dissipation mechanisms, heat cannot be dissipated in time, causing the cable surface temperature to be too high. The increase in temperature will increase the resistance of the conductor, and more heat will be generated when current passes through, forming a vicious cycle, which may eventually cause serious safety hazards such as short circuits and leakage.

[0022] like Figures 1 to 8 As shown, a computer shielded cable provided by an embodiment of the present invention comprises an outer sheath 100, a total shield layer 101, a main cable core 102 and a plurality of auxiliary cable cores 103, wherein the total shield layer 101 is arranged in the outer sheath 100, the main cable core 102 is located at the center of the total shield layer 101, the plurality of auxiliary cable cores 103 are evenly distributed around the main cable core 102 and are parallel to the main cable core 102, a spacing is arranged between two adjacent auxiliary cable cores 103, a spacing is arranged between the main cable core 102 and the plurality of auxiliary cable cores 103, a first sub-shield layer 104 is sleeved on each auxiliary cable core 103, a second sub-shield layer 105 is sleeved on the main cable core 102, and the first sub-shield layer 104 is sleeved on the main cable core 102. The second split screen layer 105 and the total screen layer 101 are used for shielding signals, the first split screen layer 104 and the second split screen layer 105 are both polygonal corrugated tube structures, and the surfaces of the first split screen layer 104 and the second split screen layer 105 have protrusions and depressions arranged alternately in sequence along the axial direction of the main cable core 102; a gap is left between the edge of the first split screen layer 104 and the surface of the corresponding auxiliary cable core 103, and a gap is left between each edge of the second split screen layer 105 and the surface of the main cable core 102, and the gap is used for the passage of cooling medium; the protrusions on the second split screen layer 105 and the depressions on each first split screen layer 104 are clamped in the axial direction of the main cable core 102.

[0023] The first split screen layer 104 and the second split screen layer 105 are connected by the protrusions and depressions thereon, which can prevent the main cable core 102 and the multiple auxiliary cable cores 103 from sliding relative to each other in the axial direction of the cable, and at the same time, can leave bending margins for the first split screen layer 104 and the second split screen layer 105, thereby reducing the damage probability of the first split screen layer 104 and the second split screen layer 105; the first split screen layer 104 with a tubular structure can improve the shielding effect of the auxiliary cable core 103, and the second split screen layer 105 with a tubular structure can improve the shielding effect of the main cable core 102. At the same time, the polygonal first split screen layer 104 and the second split screen layer 105 allow the cooling medium to pass through the surfaces of the main cable core 102 and the auxiliary cable core 103, so that the main cable core 102 and the auxiliary cable core 103 can dissipate heat better.

[0024] In this embodiment, the cross-section of the first split screen layer 104 and the second split screen layer 105 perpendicular to their own axes is a regular hexagon, the second split screen layer 105 and multiple first split screen layers 104 form a honeycomb structure, and two adjacent first split screen layers 104 in the circumferential direction of the second split screen layer 105 are clamped in the axial direction of the main cable core 102, which can improve the internal space utilization of the computer shielded cable, increase the heat dissipation effect, and at the same time increase the compressive strength of the computer shielded cable in the radial direction.

[0025] In this embodiment, six auxiliary cable cores 103 are provided, and the six auxiliary cable cores 103 are evenly distributed around the main cable core 102. After each auxiliary cable core 103 is sleeved with the first split-screen layer 104, one side of two auxiliary cable cores 103 adjacent to each other in the circumferential direction of the main cable core 102 can contact each other, and each side of the second split-screen layer 105 can contact one side of the six first split-screen layers 104 to form a honeycomb structure.

[0026] In this embodiment, the distance between two adjacent protrusions on the second split-screen layer 105 is half the distance between two adjacent protrusions on the first split-screen layer 104. Figure 5 As shown, two adjacent first split screen layers 104 can be connected to each other and can also be connected to the second split screen layer 105, so that the main cable core 102 and the auxiliary cable core 103 are more stable in their own axial direction.

[0027] In this embodiment, the total screen layer 101 is coated outside the multiple first split screen layers 104, and is bonded to the surface of the honeycomb structure composed of the multiple first split screen layers 104. The total screen layer 101 is also a polygonal corrugated tube structure. The surface of the total screen layer 101 also has protrusions and depressions alternately arranged in sequence along the axial direction of the main cable core 102. The spacing between two adjacent protrusions on the total screen layer 101 is consistent with the spacing between two adjacent protrusions on the second split screen layer 105. The total screen layer 101 can be simultaneously clamped with multiple first split screen layers 104 uniformly arranged around the second split screen layer 105. The total screen layer 101 has elasticity in its radial direction, which is convenient for the installation of the first split screen layer 104 and the second split screen layer 105.

[0028] In this embodiment, a filler 108 is provided between the outer sheath 100 and the overall shield layer 101 , and the filler 108 is used to fill the gap between the overall shield layer 101 and the outer sheath 100 , so that the computer shielded cable maintains a cylindrical shape.

[0029] In this embodiment, a spacing is provided between each surface of the first split screen layer 104 and the corresponding secondary cable core 103, a spacing is provided between each surface of the second split screen layer 105 and the main cable core 102, and a first support plate 106 is provided between the first split screen layer 104 and the corresponding secondary cable core 103, the first support plate 106 is used to connect the first split screen layer 104 and the secondary cable core 103; a second support plate 107 is provided between the second split screen layer 105 and the main cable core 102, the second support plate 107 is used to connect the second split screen layer 105 and the main cable core 102, thereby increasing the contact area between the main cable core 102 and the secondary cable core 103 and the cooling medium, and improving the heat dissipation effect of the main cable core 102 and the secondary cable core 103.

[0030] In this embodiment, the first support plates 106 and the second support plates 107 are made of rubber. The number of the first support plates 106 in each first split-screen layer 104 is consistent with the number of faces of the first split-screen layer 104. Each first support plate 106 is connected to an edge of the corresponding first split-screen layer 104. The number of the second support plates 107 in each second split-screen layer 105 is consistent with the number of faces of the second split-screen layer 105. Each second support plate 107 is connected to an edge of the corresponding second split-screen layer 105. The honeycomb structure formed by the second split-screen layer 105 and the plurality of first split-screen layers 104 makes the edges of the two first split-screen layers 104 that are in contact with each other The contact surfaces are completely fitted, and the contact surfaces of the second split screen layer 105 and each first split screen layer 104 are also completely fitted. When one of the surfaces of the first split screen layer 104 is squeezed by external force, the two first support plates 106 corresponding to the two edges adjacent to the surface exert the squeezing force on the auxiliary cable core 103 in the first split screen layer 104 through the first split screen layer 104; at the same time, when one of the edges of the first split screen layer 104 is squeezed by external force, the first support plate 106 can still exert the squeezing force on the auxiliary cable core 103 in the first split screen layer 104 through the first split screen layer 104, so that the first split screen layer 104 is not easy to deform. Similarly, the second support plate 107 also makes the second split screen layer 105 not easy to deform.

[0031] In another embodiment, the first support plate 106 and the second support plate 107 are both spiral-shaped, the first support plate 106 extends spirally along the axial direction of the first split-screen layer 104, and the second support plate 107 extends spirally along the axial direction of the second split-screen layer 105. The first support plate 106 and the second support plate 107 are spirally arranged, which makes the computer shielded cable easier to bend and provides better support for the first split-screen layer 104 and the second split-screen layer 105.

[0032] In this embodiment, the computer shielded cable also includes an external cooling mechanism, which can dissipate heat for the main cable core 102 and multiple auxiliary cable cores 103 separately. The cooling mechanism is used to fill the gap between the second sub-screen layer 105 and the main cable core 102 and the gap between each first sub-screen layer 104 and the auxiliary cable core 103 with cooling liquid or cold air to cool the main cable core 102 and the auxiliary cable core 103. At the same time, the cooling mechanism can separately control the flow rate of the cooling liquid or cold air in the gap between the second sub-screen layer 105 and the main cable core 102 and the gap between each first sub-screen layer 104 and the auxiliary cable core 103, so as to perform targeted heat dissipation according to the heat generation of the main cable core 102 and the auxiliary cable core 103.

[0033] The working principle of a computer shielded cable provided in the above embodiment is: First, the metal tube can be made into the first sub-screen layer 104, the second sub-screen layer 105 and the total screen layer 101 by a tube expander, and then the first support plate 106 is installed in the first sub-screen layer 104 by adhesive, and the second support plate 107 is installed in the second sub-screen layer 105 by adhesive, and then the main cable core 102 is inserted into the second sub-screen layer 105, and the auxiliary cable core 103 is inserted into the first sub-screen layer 104. During the insertion process of the main cable core 102 and the auxiliary cable core 103, the insertion resistance of the main cable core 102 and the auxiliary cable core 103 can be reduced by rotation.

[0034] After the main cable core 102 and the auxiliary cable core 103 are inserted into the corresponding second split screen layer 105 and the first split screen layer 104, the multiple first split screen layers 104 are sequentially attached to the second split screen layer 105, the protrusions of the first split screen layer 104 are inserted into the depressions of the second split screen layer 105, and the two adjacent first split screen layers 104 are clamped by the protrusions and the depressions. At this time, the second split screen layer 105 and the multiple second split screen layers 105 form a honeycomb shape, and then are inserted into the total screen layer 101. When the protrusions on the total screen layer 101 contact the protrusions on the first split screen layer 104, the total screen layer 101 will expand outward along its own radial direction, so that the multiple first split screen layers 104 can be installed in the total screen layer 101, and finally the protrusions on the first split screen layer 104 contact the depressions on the total screen layer 101. At this time, the total screen layer 101 wraps the second sub-screen layer 105 and the first sub-screen layers 104 together, and then the filler 108 is placed on the surface of the total screen layer 101, so that the outer sheath 100 wraps the total screen layer 101 and presents a round shape.

[0035] When the computer shielded cable is in use, cooling liquid or cold air is introduced between the first sub-screen layer 104 and the auxiliary cable core 103 and between the second sub-screen layer 105 and the main cable core 102 through the cooling mechanism to cool the main cable core 102 and the auxiliary cable core 103.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
