[0002] At present, communication cable is an important component in signal transmission field, and is widely used in various digital communication systems, including telephone network, local area network, data center, optical fiber communication, 5G communication and other fields. The main function of communication cable is to transmit electrical signals, power or data. In order to ensure the stability and quality of signals during signal transmission, a shielding layer is usually provided on the outside of the communication cable to reduce the influence of external signals on the communication cable.

[0003] Communication cables are usually deployed in complex environments, and electromagnetic interference can affect signal transmission quality. In some communication cable application scenarios, signal integrity and anti-interference capability are very important. Traditional communication cables use metal materials such as aluminum foil and copper as conductors and shielding materials. Using metal materials as shielding materials results in high material cost of the cable and heavy weight of the cable, which increases the transportation and installation cost of the cable. Moreover, the cable material is easily damaged in some environments, affecting the service life of the cable. SUMMARY

[0021] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1

[0023] like Figure 1 As shown, a graphene-shielded digital communication cable includes a signal transmission layer, a shielding layer, and a sheath layer 6.

[0024] The signal transmission layer consists of at least two wire cores 1. In this embodiment, the number of wire cores 1 is 5. The wire cores 1 can transmit signals or data. Each wire core 1 is fixed by twisting together to form a tight twisted wire structure. The twisted structure of the wire cores 1 can increase the cable's anti-interference ability and reduce signal crosstalk. The twisted structure can also prevent the electromagnetic fields generated during signal transmission from canceling each other out, thus reducing signal interference.

[0025] An insulation layer 2, made of polyethylene, is located on the outside of each wire core 1. This insulation layer 2 isolates each wire core 1 from the external shielding layer 3 or other wire cores 1, preventing short circuits or signal interference. The insulation layer 2 protects the signal transmission channel, ensuring stable signal transmission.

[0026] A shielding layer 3 is provided on the outside of the insulation layer 2, wrapping around the outside of the insulation layer 2. This shielding layer 3 provides electromagnetic shielding, preventing external electromagnetic interference from affecting signal transmission quality. In this embodiment, the shielding layer 3 is made of graphene material. The shielding layer 3 is evenly distributed on the outside of the insulation layer 2, with the shielding layers 3 between different wire cores 1 in contact with each other, reducing the overall volume of the communication cable. By providing a shielding layer 3 on the outside of the insulation layer 2, signal leakage and the influence of external electromagnetic waves on the signal can be prevented. The shielding layer also reduces the electromagnetic radiation of the communication cable, ensuring that the communication cable is suitable for high-speed, high-bandwidth digital signal transmission.

[0027] A metal layer 4 is disposed outside the shielding layer 3. In this embodiment, an insulation layer 2 and a shielding layer 3 are disposed outside the core 1. The five cores are twisted together, and the shielding layers 3 disposed outside the core 1 are in contact with each other to form a whole. The metal layer 4 is disposed outside this whole. The metal layer 4 adopts a single-turn structure and only wraps the outside of the shielding layer 3. The metal layer 4 can provide additional shielding effect and enhance the overall mechanical strength of the cable. The metal layer 4 is made of aluminum foil. The metal layer 4 can further improve the cable's anti-electromagnetic interference capability. The aluminum foil material can effectively reduce the interference of external electromagnetic waves on the cable and ensure the overall stability of signal transmission. In addition, the metal layer 4 can also increase the structural strength of the cable and prevent the cable from being damaged by external forces during use.

[0028] A tensile layer 5 is provided on the outside of the metal layer 4. In this embodiment, the tensile layer 5 is made of aramid fiber. It can improve the tensile strength and compressive strength, preventing the cable from breaking or being damaged during stretching or bending. The main function of the tensile layer 5 is to increase the overall tensile strength of the communication cable, preventing damage to the internal structure of the communication cable caused by external forces during transportation, installation, or use; the tensile layer 5 also protects the cable from mechanical damage.

[0029] A sheath layer 6 is provided outside the tensile layer 5, wrapping around the outside of the tensile layer 5. In this embodiment, the sheath layer 6 is made of PVC. The sheath layer 6 provides external protection for the communication cable, reducing physical damage to the cable in the external environment and providing a certain degree of water resistance and UV resistance. The outer sheath layer provides final mechanical protection for the communication cable, ensuring that the cable is not damaged by external forces in harsh environments and guaranteeing its use in various complex environments.

[0030] In this embodiment, after the core 1 is twisted, there is a certain gap between the shielding layer 3 and the metal layer 4. A filler rope is provided in the gap to fill it and ensure the overall stability and integrity of the communication cable. The filler rope provides a certain mechanical support to ensure that the shielding layer does not deform or loosen during use, and to ensure the overall structural stability of the cable and enhance the compressive strength of the communication cable.

[0031] In this embodiment, the conductors 1 are separated by the insulation layer 2 to ensure that there is no contact or interference between the conductors 1, thus ensuring the stability of signal transmission. The shielding layer 3 covers the outside of the insulation layer to prevent interference from external electromagnetic waves to the conductors 1. A metal layer 4 is provided outside the shielding layer 3 to wrap the shielding layer 3, which further enhances the shielding effect of the cable and improves the overall mechanical strength of the cable, protecting it from physical damage. A tensile layer 5 is provided outside the metal layer. The tensile layer 5 increases the overall tensile strength of the communication cable, ensuring that the communication cable will not be damaged or deformed under long-term use or mechanical tension. A sheath layer 6 is provided outside the tensile layer 5. The sheath layer 6 can prevent damage to the cable from the external environment and provides additional electrical insulation protection.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
