Description

Technical Field

[0002] Carbon core cables mainly refer to cables that use carbon nanotubes or carbon fiber composite materials as core wires. These materials, with their unique physical and chemical properties, give carbon core cables multiple properties superior to traditional cables, such as high conductivity, low resistivity, anti-electromagnetic interference, long life and light weight. However, they also face some challenges in practical applications.

[0031] The present invention provides a safe and durable carbon core cable. An effective buffer system is formed by arranging a first deformation layer 3, a second deformation layer 4, a buffer cavity 5 and a support member 6. When the cable is squeezed externally, the second deformation layer 4 squeezes the first deformation layer 3, and both the second deformation layer 4 and the first deformation layer 3 undergo elastic deformation. The buffer cavity 5 provides a buffer space at this time, reducing the direct impact on the carbon core 1, thereby reducing the risk of damage to the internal carbon core 1; when the internal carbon core 1 expands due to power-on heating, the first deformation layer 3 squeezes the second deformation layer 4, and both the first deformation layer 3 and the second deformation layer 4 undergo elastic deformation.

[0032] The present invention provides a safe and durable carbon core cable, which can effectively conduct the heat generated by the internal carbon core 1 to the outside of the protective layer 10 by providing a heat conductive strip 13, thereby slowing down the degree of thermal expansion of the internal carbon core 1, thereby further reducing the risk of cable rupture.

[0033] The present invention provides a safe and durable carbon core cable. By setting a shielding layer 7, it can effectively shield electromagnetic interference and protect the stability of signal transmission inside the cable; by setting a waterproof layer 8, it can prevent moisture from invading the inside of the cable, avoiding problems such as reduced insulation performance or short circuit due to moisture; by setting a flame retardant layer 9, it can effectively prevent the spread of fire when the cable encounters a fire source, thereby reducing the risk of fire; by setting a protective layer 10, it is directly exposed to the outside world, thereby enhancing the wear resistance of the cable; by setting a reinforcing rib 11, the mechanical strength of the cable is improved, and the compressive resistance and structural stability of the cable are further enhanced; by setting a wear-resistant protrusion 12, when the cable rubs against a contact surface such as the ground, the wear-resistant protrusion 12 is first in contact and rubbed with the ground, thereby further enhancing the wear resistance of the cable.

[0034] The present invention provides a safe and durable carbon core cable, which realizes multi-layer protection of the internal structure of the cable, improves the durability and safety of the cable, helps to extend the service life of the cable, and can maintain stable performance in various complex environments.

[0035] like Figure 1 As shown, in this embodiment, the outer layer of the first deformation layer 3 protrudes to form a plurality of first plug blocks 14, and the outer layer of the first deformation layer 3 is recessed to form a plurality of second slots 15, the inner layer of the second deformation layer 4 protrudes to form a plurality of second plug blocks 16, and the inner layer of the second deformation layer 4 is recessed to form a plurality of first slots 17, the first plug blocks 14 are plugged into and matched with the first slots 17, and the second plug blocks 16 are plugged into and matched with the second slots 15.

[0036] The plug-in design makes the connection between the first deformation layer 3 and the second deformation layer 4 tighter and stronger. This connection method can effectively prevent relative sliding or misalignment between the first deformation layer 3 and the second deformation layer 4, thereby enhancing the overall structural stability of the cable.

[0037] like Figure 1 As shown, in this embodiment, the first plug-in blocks 14 and the second plug-in blocks 16 are arranged alternately; the alternately arranged first plug-in blocks 14 and the second plug-in blocks 16 make the connection between the first deformation layer 3 and the second deformation layer 4 tighter and stronger.

[0038] like Figure 1 and 2 As shown, in this embodiment, the wear-resistant protrusion 12 is hollow, and the thermally conductive strip 13 extends into the cavity of the wear-resistant protrusion 12; the thermally conductive strip 13 extends into the cavity of the wear-resistant protrusion 12, forming a more efficient heat dissipation channel, which can more effectively conduct the heat generated inside the cable to the outside of the cable, and the wear-resistant protrusion 12 can also protect the thermally conductive strip 13. When the cable rubs against the contact surface such as the ground, the wear-resistant protrusion 12 is the first to contact and rub against the ground, and the thermally conductive strip 13 will not be damaged by friction first.

[0039] like Figure 3 As shown, in this embodiment, the reinforcing rib 11 is spiral; the spiral reinforcing rib 11 can significantly enhance the overall structural strength of the cable. By spirally winding along the axial direction of the cable, the reinforcing rib 11 is tightly combined with the protective layer 10 to form a more solid whole.

[0042] The rubber material has good insulation properties, which can effectively isolate the conductor inside the cable from the external environment, prevent current leakage, and ensure the electrical safety of the cable. In addition, the rubber material has a certain elasticity, which can deform when the cable is subjected to external force, and quickly return to its original state after the external force is removed, further enhancing the cable's compressive strength and structural stability; copper foil is used as the shielding layer 7 material to effectively block external electromagnetic interference signals from entering the cable, and also prevent the internal signals of the cable from radiating outward, ensuring the stability and safety of the cable transmission signal; polyvinyl chloride material has good waterproof properties, which can effectively prevent moisture from penetrating into the cable, protecting the cable's internal The structure is not damaged; alumina, as a flame retardant material, can quickly form a hard protective layer when the cable encounters fire, preventing the spread of flames and the release of combustion products, thereby improving the flame retardant properties of the cable; polyethylene material has good wear resistance, can resist external mechanical wear and scratches, and protect the internal structure of the cable from damage; steel wire, as the material of the reinforcing rib 11, can significantly improve the mechanical strength of the cable, allowing the cable to withstand greater tension and pressure; ceramic material has excellent thermal conductivity, can quickly conduct the heat generated inside the cable to the external environment, reduce the operating temperature of the cable, and improve the heat dissipation efficiency of the cable, thereby slowing down the heat expansion of the internal carbon core 1.

[0043] like Figure 1 As shown, in this embodiment, a plurality of buffer cavities 5 are provided, and the plurality of buffer cavities 5 are evenly distributed between the first deformation layer 3 and the second deformation layer 4; the plurality of evenly distributed buffer cavities 5 enable the first deformation layer 3 and the second deformation layer 4 to be evenly dispersed when elastic deformation occurs.

[0044] like Figure 1 and 2 As shown, in this embodiment, a plurality of heat-conducting bars 13 are provided, and the plurality of heat-conducting bars 13 are evenly distributed on the insulating layer 2; the evenly distributed plurality of heat-conducting bars 13 can effectively improve the heat dissipation efficiency, and can also evenly dissipate the heat, further slowing down the degree of heat expansion of the internal carbon core 1.

[0045] like Figure 1 and 2 As shown, in the present embodiment, a plurality of wear-resistant protrusions 12 are provided, and the plurality of wear-resistant protrusions 12 are evenly distributed on the protective layer 10; the evenly distributed plurality of wear-resistant protrusions 12 can ensure that when the cable rubs against a contact surface such as the ground, the wear-resistant protrusions 12 are the first to contact and rub against the ground, thereby further enhancing the wear resistance of the cable.

[0046] Working principle: When the safe and durable carbon core cable provided by the present application is in use, when the cable is subjected to external compression, the second deformation layer 4 will squeeze the first deformation layer 3, and both the second deformation layer 4 and the first deformation layer 3 will undergo elastic deformation. The buffer cavity 5 provides a buffer space at this time to reduce the direct impact on the carbon core 1, thereby reducing the risk of damage to the internal carbon core 1; when the internal carbon core 1 expands due to power-on heat, the first deformation layer 3 will squeeze the second deformation layer 4, and both the first deformation layer 3 and the second deformation layer 4 will undergo elastic deformation. The buffer cavity 5 provides a buffer space at this time to reduce the direct impact on the protective layer 10, thereby reducing the risk of cable rupture.
