Therefore, a composite cable has emerged that integrates the functions of network cables and coaxial cables. This not only simplifies wiring work but also meets the diverse needs of modern communications and multimedia transmission.

[0020] To help those skilled in the art better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings. The embodiments described herein are merely a portion of the present invention, not all of the present invention. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0021] refer to Figure 1 As shown, a composite cable of a network cable and a coaxial cable comprises a cable outer sheath 1, a network cable 2 and a coaxial cable 3. The coaxial cable 3 is installed on one side of the cable outer sheath 1, and the network cable 2 is installed on the other side of the cable outer sheath 1.

[0022] Specifically, the outer surfaces of the coaxial cable 3 and the network cable 2 are each provided with an insulating layer 4, an elastic heat-resistant layer 5, and an inner shielding layer 6, in that order. The insulating layer 4 is provided with a heat-dissipating coating (not shown). In this embodiment, the insulating layer 4 is made of high-density polyethylene, the elastic heat-resistant layer 5 is made of thermosetting plastic, and the inner shielding layer 6 is a galvanized copper wire braid.

[0023] The primary function of the insulation layer 4 is to provide electrical insulation, ensuring that the coaxial cable 3 and network cable 2 do not come into electrical contact with the outside world or other conductors during signal transmission, thereby preventing safety issues such as short circuits and leakage. The design of the elastic temperature-resistant layer 5 enables the cable to maintain stable performance over a wide temperature range. The inner shielding layer 6 is primarily used to shield against external electromagnetic interference, effectively preventing signal interference between the network cable 2 and the coaxial cable 3, and preventing signal distortion when the composite cable is transmitting, effectively improving signal transmission quality.

[0024] The coaxial cable 3 further includes a cable core 31 , and a plurality of flexible copper conductors 32 are provided on the outside of the cable core 31 and arranged around the cable core.

[0025] The inner shielding layer 6 is provided with outwardly extending heat dissipation protrusions 7 on its surface. The heat dissipation protrusions 7 are staggered at the mating sidewalls of the inner shielding layer 6 of the coaxial cable 3 and the inner shielding layer 6 of the network cable 2, thereby forming a heat dissipation gap 8 between the inner shielding layer 6 of the coaxial cable 3 and the inner shielding layer 6 of the network cable 2 at the mating location. In this embodiment, the heat dissipation protrusions 7 are circular and made of an elastic material, allowing the network cable 2 and the coaxial cable 3 to form a heat dissipation gap 8 and maintain a tight fit when twisted together.

[0026] By setting the heat dissipation protrusions 7, the heat dissipation surface area of the network cable 2 and the coaxial cable 3 can be increased. At the same time, the heat dissipation protrusions 7 at the docking side walls of the network cable 2 and the coaxial cable 3 are staggered, so that a heat dissipation gap 8 is formed between the network cable 2 and the coaxial cable 3, avoiding the technical problem of the network cable 2 and the coaxial cable 3 being stuck together when twisted, which makes it difficult to dissipate heat. This can effectively improve the heat dissipation performance inside the composite cable composed of the network cable 2 and the coaxial cable 3, and ensure the normal use of the composite cable.

[0027] The cable outer sheath 1 comprises a heat dissipation layer 101, an outer shielding layer 102, and an anti-fracture jacket layer 103. These heat dissipation layer 101, outer shielding layer 102, and anti-fracture jacket layer 103 are coaxially arranged and arranged sequentially away from the coaxial cable 3. In this embodiment, the outer shielding layer is an aluminum foil shielding layer; the anti-fracture jacket layer 103 is made of a cross-braided nylon yarn. The outer shielding layer 102 effectively shields external electromagnetic interference, protecting the signal transmission within the composite cable from external influences and further ensuring signal quality. The anti-fracture jacket layer 103 has a high fracture strength, capable of resisting external impact and mechanical wear, protecting the cable's internal structure from damage.

[0028] In which, the heat dissipation layer 101 includes a heat dissipation inner layer and an outer heat dissipation layer (not shown in the figure) arranged in sequence along the direction away from the coaxial cable 3, and a plurality of support ribs 112 are arranged in the cavity (not marked in the figure) between the heat dissipation inner layer and the heat dissipation outer layer along the length direction of the cable. The support ribs 112 divide the cavity into a plurality of heat dissipation cavities 111, and a heat dissipation pipe 113 is provided in each heat dissipation cavity. The heat dissipation pipe 113 and the support ribs 112 are both made of elastic material, and the heat dissipation pipe 113 is filled with coolant.

[0029] The coolant circulating in the heat pipes 113 rapidly absorbs and removes heat generated within the cable, dissipating it into the surrounding environment through the surface of the heat dissipation layer 101. This achieves efficient heat conduction and heat dissipation, further improving the heat dissipation performance of the composite cable. The support ribs 112 not only separate the heat dissipation cavity 111 but also provide additional structural support, preventing deformation or damage to the heat dissipation layer due to temperature fluctuations or external forces. The heat pipes 113 and support ribs 112 are made of an elastic material, allowing them to adapt to minor deformations of the composite cable during use while maintaining stable heat dissipation performance.

[0030] The composite network cable and coaxial cable provided by this utility model also includes several reinforcing cores 9, which fill the gaps between the coaxial cable 3, the network cable 2, and the cable outer sheath 1. The addition of reinforcing cores 9 disperses tensile forces within the composite cable and provides additional support, thereby increasing the tensile strength of the composite cable, helping to maintain the stability of the cable's internal structure and ensure signal transmission quality. The reinforcing cores 9 comprise an aramid core, which is covered with a PVC sheath.

[0031] A flame retardant layer (not shown) is provided between the anti-fracture sheath layer 103 and the outer shielding layer 102. The flame retardant layer is made of flame retardant polyvinyl chloride material. The flame retardant layer can significantly improve the flame retardant performance of the cable and enhance the overall safety and stability of the composite cable.

[0032] The anti-fracture jacket layer 103 is provided with a wear-resistant surface layer 10, the outer surface of which is provided with a concave arc surface 11. The wear-resistant surface layer 10 is used to resist physical damage such as mechanical wear and scratching, protecting the inner anti-fracture jacket layer 103 from damage. The concave arc surface increases the friction between the composite cable and the external contact surface, improving the anti-slip performance of the composite cable.

[0033] The present invention provides a composite cable of a network cable and a coaxial cable. Through the design of the inner and outer shielding layers, signal interference between the network cable 2 and the coaxial cable 3 can be effectively avoided, and the signal interference of the composite cable to the outside world can also be shielded; at the same time, a heat dissipation gap 8 is formed at the docking position between the inner shielding layer 6 of the coaxial cable 3 and the inner shielding layer of the network cable 2 through the heat dissipation protrusion 7 and the heat dissipation protrusion 7, which can increase the heat dissipation area of the network cable 2 and the coaxial cable 3, and combined with the arrangement of the heat dissipation coating and the heat dissipation layer 101, the heat dissipation performance of the composite cable is greatly improved, the signal transmission quality is further guaranteed, and it is beneficial to prolong the service life of the composite cable.

[0034] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention and are not intended to limit the present invention to the specific embodiments described. Obviously, other modifications and variations may be made based on the contents of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. They are not intended to limit the present invention, and any simple variations of the present invention fall within the scope of protection of the present invention.
