[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 2 - Figure 4The utility model provides an embodiment: a corrosion-resistant wire and cable, comprising a protective sleeve 1, the outer wall of the protective sleeve 1 is provided with staggered protrusions 2 and a fixing ring 3, the surfaces of the protective sleeve 1, the protrusions 2 and the fixing ring 3 are all provided with a polyurethane coating, an armor layer 4 is arranged inside the protective sleeve 1, a shielding layer 1 5 is arranged inside the armor layer 4, a waterproof layer 6 is arranged inside the shielding layer 1 5, a shielding layer 2 7 is arranged inside the waterproof layer 6, an insulating layer 1 8 is arranged inside the shielding layer 2 7, an expansion component is arranged inside the shielding layer 1 5, and a support component is arranged inside the insulating layer 1 8, the expansion component includes a groove 1 9 and a groove 2 10, and the groove 1 9 and the groove 2 10 are both provided in plurality, and the plurality of grooves 1 9 are respectively opened on the inner wall of the shielding layer 1 5, and the plurality of grooves 2 10 are respectively opened on the outer wall of the shielding layer 2 7, and the plurality of grooves 1 9 correspond to the plurality of grooves 2 10, and the plurality of grooves 1 9 correspond to the outer side of the waterproof layer 6, and the plurality of grooves 2 10 correspond to the inner side of the waterproof layer 6, and the plurality of protrusions 2 are respectively higher than the plurality of fixing rings 3.
[0033] The polyurethane coating on the surface of the protective sleeve 1, the protrusion 2 and the fixing ring 3 increases the corrosion resistance and wear resistance, and at the same time improves the overall safety performance. When holding the protective sleeve 1, the multiple protrusions 2 increase the friction between the surface of the protective sleeve 1 and the hand. One of the fixing rings 3 is convenient for using tools to clamp the protective sleeve 1, so as to keep the stability of the protective sleeve 1 and avoid gaps and shaking when clamping multiple protrusions 2. The multiple protrusions 2 are higher than the multiple fixing rings 3. When the protective sleeve 1 falls on the ground, it will contact the multiple protrusions 2. Through the friction between the multiple protrusions 2 and the ground, the protective sleeve 1 slides on the ground. The armor layer 4 is a mesh structure woven by metal wires. The armor layer 4 provides further mechanical protection to the interior. The shielding layer 1 5 and the shielding layer 2 7 reduce or eliminate electromagnetic interference and radio frequency interference to avoid internal signal leakage. The waterproof layer 6 prevents moisture from penetrating into the interior. When the waterproof layer 6 encounters moisture and expands, it will be accommodated by the multiple grooves 1 9 and the multiple grooves 2 10 to provide space for the waterproof layer 6 to expand up and down.
[0034] Reference Figure 1 , Figure 2 and Figure 5 The support assembly includes a support block 13, and the support blocks 13 are arranged in plurality. One ends of the plurality of support blocks 13 are respectively fixedly connected to the inner wall of the insulating layer 8, and the other ends of the plurality of support blocks 13 are respectively fixedly connected to support rods 12, and elastic core shafts 11 are fixedly connected between the plurality of support rods 12. Insulating layer 2 14 is arranged around the inside of the insulating layer 8, and wire cores 15 are arranged inside the plurality of insulating layer 2 14, and the plurality of insulating layer 2 14 are respectively arranged at the edges of the plurality of support rods 12. A uniformly distributed filling layer 16 is arranged inside the support rod 12, and the plurality of filling layers 16 are respectively arranged between the plurality of insulating layer 2 14, the plurality of support rods 12 and the plurality of support blocks 13, and the protective sleeve 1 and the elastic core shaft 11 are parallel to each other.
[0035] The multiple support rods 12 are fixed by an elastic core shaft 11, and the multiple support blocks 13 are used to fix the multiple support rods 12 and support the insulation layer 8 respectively, so as to prevent the insulation layer 8 from being squeezed and causing depression. At the same time, the wire cores 15 in the multiple insulation layers 14 are separated, and the current leakage of the multiple wire cores 15 is prevented by the insulation layer 18 and the multiple insulation layers 14 to ensure the safety during the transmission of electric energy. The thermal stability of the multiple wire cores 15 is provided by the multiple filling layers 16 to reduce the expansion and contraction caused by temperature changes. At the same time, the multiple insulation layers 14 are stabilized in the insulation layer 8. The protective sleeve 1 and the elastic core shaft 11 are parallel to each other. When the protective sleeve 1 is rolled up, the elastic core shaft 11 is used to make the inner part have a smaller bending radius while maintaining the integrity of the internal structure.
[0036] Working principle: The polyurethane coating on the surface of the protective sleeve 1, the protrusion 2 and the fixing ring 3 increases the corrosion resistance and wear resistance. When in use, the multiple protrusions 2 make it easy to hold the protective sleeve 1 and increase the friction with the hand. At the same time, the multiple protrusions 2 can increase the friction of the protective sleeve 1 on the ground to prevent the protective sleeve 1 from sliding on the ground. One of the fixing rings 3 makes it easy to clamp the protective sleeve 1 using tools and equipment. The armor layer 4 protects the interior, and the shielding layer 1 5 and the shielding layer 2 7 reduce or eliminate electromagnetic interference and radio frequency interference. When the waterproof layer 6 expands when exposed to water, it is accommodated to a certain extent by the multiple grooves 1 9 and the multiple grooves 2 10. The multiple support rods 12 fixed on the outer wall of the elastic core shaft 11 are respectively fixed to the multiple support blocks 13 to support the insulating layer 1 8. At the same time, the multiple cores 15 can be separated, and the safety of the multiple cores 15 transmitting electrical energy is ensured by the insulating layer 1 8 and the multiple insulating layers 2 14. The multiple insulating layers 2 14 are secured in the insulating layer 1 8 by the multiple filling layers 16.
