[0004] To address the aforementioned problems, this application proposes a high-temperature resistant computer cable. Utility Model Content

[0017] This invention combines a gradient heat-resistant structure with a dynamic heat dissipation structure and a self-expanding protective structure to slow down external-to-inward conduction during cable use, thereby ensuring the cable's operating temperature and avoiding signal attenuation.

[0018] The self-expanding structure of this invention can also expand when exposed to an external open flame, thereby sealing the gaps to block oxygen and thus preventing the flame from spreading along the cable gaps.

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.

[0031] 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.

[0032] Please see Figure 1-3 As shown, this utility model is a high-temperature resistant computer cable, including cable 1;

[0033] The cable 1 is provided with a conductor 11, an insulation layer 12, a dynamic heat dissipation layer 13, and a sheath layer 14 from the inside out;

[0034] The insulation layer 12 is divided into an inner insulation layer 121 and an outer insulation layer 122. The inner insulation layer 121 is irradiated cross-linked polyolefin, which slows down the conduction of external heat inward. The outer insulation layer 122 is a composite tape of mica and polyimide spirally wrapped around the outside of the inner insulation layer 121 to reflect radiant heat. The dynamic heat dissipation layer 13 is a mixed woven mesh of nickel-plated copper wire and glass fiber, with thermistor wires embedded in the mesh. It triggers an automatic short circuit alarm at a temperature of 110°C. The inner and outer layers of the sheath layer 14 are filled with an expansion strip 142, which is sodium silicate gel containing intercalated graphite. When heated, the volume expands by 4 to 5 times, thereby filling the gaps to block oxygen and prevent the flame from spreading along the cable 1.

[0035] Furthermore, the inner layer of the sheath layer 14 is a modified silicone rubber sheath with 5-8 vol% boron nitride nanosheets added, and the outer layer is a halogen-free flame-retardant polyether ether ketone sheath.

[0036] Furthermore, the dynamic heat dissipation layer 13 has a braiding angle of 40° to 50°, and the proportion of nickel-plated copper wire is 60% to 70%.

[0037] Furthermore, a spiral tensile section 15 is provided on the outer side of the sheath layer 14, and the inner layer of the tensile section 15 is integrally formed with aramid yarn to disperse the bending stress of the cable 1, thereby achieving uniform crack propagation to protect the structure of the cable 1 from large-area cracking.

[0038] It is understood that the cable 1 of this utility model can form a dual heat-resistant function of damping and reflection during use, and automatically block oxygen when exposed to open flame to prevent the flame from spreading inward and along the edge. Finally, it can also disperse the stress during bending to suppress cracking and protect the integrity of the overall structure.

[0039] A specific application of the operation process of this embodiment is as follows: During use, the inner insulating layer 121 inside the cable 1 slows down the conduction of external heat inward, and the outer insulating layer 122 reflects radiant heat, thereby maintaining the temperature performance of the cable 1 during operation; then, when an open flame appears outside, the expansion strip 142 is heated and expands to seal the gaps and block oxygen, thereby preventing the flame from conducting inward and spreading along the cable 1; finally, the combination of the tensile part 15 and the aramid yarn disperses the bending stress and promotes uniform crack propagation, solving the problem that the cable 1 is prone to cracking when bent.
