[0002] Cables are essential basic equipment for transmitting electrical energy, transmitting information, and manufacturing various motors, instruments, and meters to realize electromagnetic energy conversion. They are necessary basic products in the future electrified and information-based society. Shielded cables are cables with a shielding layer added after they are bundled. The shielding layer reflects, absorbs, and has a skin effect on electromagnetic waves to prevent external electromagnetic interference from entering the cable, while also preventing internal signals from radiating out and interfering with the operation of other equipment.
[0003] Currently, computer cables are generally designed to improve their shielding performance to ensure stable information transmission, but the stability of the cables is often overlooked. Existing twisted-pair double-shielded computer cables lack internal stress-bearing structures, which can cause damage to long-distance cables when pulled horizontally or vertically due to excessive stress.

A first silicone layer is disposed within the second silicone layer. A silicone support plate is disposed between the first and second silicone layers.

Each twisted-pair core is disposed within a receiving area. An inner shielding layer is disposed outside each twisted-pair core. An outer shielding layer is wrapped around the second silicone layer.
[0007] Furthermore, a wrapping layer is provided between the twisted pair core and the inner shielding layer, and two tensile strips are provided inside the wrapping layer, while a second tensile strip is fixedly provided inside the silicone layer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0025] Please see Figure 1-3 As shown, this utility model is a twisted-pair double-shielded computer cable, including multiple sets of twisted-pair cores 1. Each twisted-pair core 1 is disposed within a second silicone layer 8. A first silicone layer 6 is disposed within the second silicone layer 8. A silicone support plate 9 is disposed between the first silicone layer 6 and the second silicone layer 8. The silicone support plate 9 divides the area between the first silicone layer 6 and the second silicone layer 8 into receiving areas equal to the number of twisted-pair cores 1. Each twisted-pair core 1 is disposed within one of these receiving areas. An inner shielding layer 2 is disposed outside each twisted-pair core 1. An outer shielding layer 11 is wrapped around the second silicone layer 8. The inner shielding layer 2 and the outer shielding layer 11... All use metal mesh shielding film. In this embodiment, the twisted core 1 is set in the receiving area formed by silicone support plate 9, silicone layer 6 and silicone layer 8. Multiple sets of twisted core 1 are set individually to prevent friction and collision damage between the twisted core 1. After the cable is subjected to force, silicone layer 6, silicone layer 8 and silicone support plate 9 will deform to bear the force and prevent damage to the twisted core 1. The inner shielding layer 2 can prevent the external electromagnetic field from affecting the twisted core 1 and also prevent the electromagnetic field between the twisted core 1. The outer shielding layer 11 can further improve the shielding capability of the cable.
[0026] Furthermore, a wrapping layer 101 is provided between the twisted pair core 1 and the inner shielding layer 2. Two tensile strips 5 are provided inside the wrapping layer 101, and a tensile strip 7 is fixedly provided inside the silicone layer 6. In this embodiment, the tensile strength of the cable is improved by tensile strips 5 and 7, preventing the cable from being subjected to large tensile forces when only the twisted pair core 1 bears the force, thus ensuring the structural stability of the twisted pair core 1.
[0027] The inner shielding layer 2 is provided with an insulating layer 3 outside, and the receiving area of the twisted pair core 1 is filled with an inorganic mineral mica tape filling layer 10. In this embodiment, there is a silicone layer 8, an insulating layer 3 and an inorganic mineral mica tape filling layer 10 between the outer shielding layer 11 and the inner shielding layer 2. The silicone layer 8, the insulating layer 3 and the inorganic mineral mica tape filling layer 10 all have good insulation capabilities, ensuring the independence of the shielding effects of the outer shielding layer 11 and the inner shielding layer 2.
[0028] The silicone support plate 9 is configured as a mesh. In this embodiment, the silicone support plate 9 is configured as a mesh, which can reduce material costs and improve the elongation performance of the silicone support plate 9.
[0029] The wrapping layer 101 is filled with foam 4. In this embodiment, the foam 4 filled in the wrapping layer 101 can protect the twisted pair core 1 and prevent wear on the outer layer of the twisted pair core 1. At the same time, when the cable is bent under force, the foam 4 can also play a certain buffering role and improve the cable's load-bearing capacity.
[0030] The outer shielding layer 11 is wrapped with an armor layer 12, the armor layer 12 is wrapped with a heat insulation layer 13, the heat insulation layer 13 is wrapped with a waterproof layer 14, the waterproof layer 14 is wrapped with a flame-retardant layer 15, and the flame-retardant layer 15 is wrapped with an outer sheath 16. In this embodiment, the outer sheath 16 is located on the outermost side of the cable and has good wear resistance, thus protecting the cable. The flame-retardant layer 15 gives the cable flame-retardant properties, preventing the cable from catching fire. The waterproof layer 14 can effectively prevent moisture from penetrating into the cable, protecting the cable's insulation material and conductor from moisture damage and improving the cable's service life. The armor layer 12 can further increase the cable's mechanical strength, making it more resistant to external mechanical damage. The heat insulation layer 13 prevents the external high or low temperature environment from directly affecting the twisted pair core 1.
[0031] It is understandable that, firstly, this utility model improves the overall stability of the cable through silicone layer 6, silicone layer 8 and silicone support plate 9, and secondly, it improves the tensile strength of the cable through tensile strip 5 and tensile strip 7, preventing the cable from being subjected to large tensile forces when only the twisted pair core 1 bears the force, thus ensuring the structural stability of the twisted pair core 1.
[0032] A specific application of this embodiment is as follows: when the cable is subjected to external impact, the silicone layer 6, silicone layer 8, and silicone support plate 9 will deform to bear the force and prevent damage to the twisted pair core 1. At the same time, the foam 4 will also play a certain buffering role, improving the cable's load-bearing capacity. When the cable is subjected to a large tensile force, the tension strips 5 and 7 can prevent the twisted pair core 1 from bearing the force alone, ensuring the structural stability of the twisted pair core 1. The inner shielding layer 2 of the cable can prevent external electromagnetic fields from affecting the twisted pair core 1 and also prevent the electromagnetic fields between the twisted pair core 1 from affecting each other. The outer shielding layer 11 can further improve the shielding capability of the cable. By setting multiple sets of twisted pair core 1 individually, friction and collision damage between the twisted pair core 1 can be prevented.
