Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically to a wire and cable with high-efficiency compressive strength. Background Technology

[0002] As the core carriers of power transmission and signal transmission, wires and cables are widely used in many fields such as energy, transportation, and communication. With the rapid development of modern industry, urban construction, and intelligent facilities, the operating environment of wires and cables is becoming increasingly complex. In scenarios such as underground pipe corridors and rail transit, cables need to withstand soil pressure, mechanical compression, and vibration impact for a long time. In environments such as high-voltage power transmission and data centers, cables also face challenges such as electromagnetic interference and temperature changes. Therefore, wires and cables with high-efficiency pressure resistance and electromagnetic protection capabilities have become a key requirement for ensuring stable power and signal transmission and improving system reliability.

[0003] However, traditional wires and cables have relatively simple structural designs, often employing simple armor or sheath layers to resist external pressure. Their compressive strength is limited, and under high-intensity or continuous pressure, they are prone to structural deformation and insulation damage, leading to cable failures and even safety accidents. In terms of electromagnetic protection, traditional cables typically only have a single-layer shielding structure, which is insufficient to effectively cope with complex electromagnetic interference, easily causing signal transmission distortion and increased power loss. Furthermore, the internal structural layout of traditional cables lacks optimization, resulting in low space utilization efficiency and failing to meet the demands of modern engineering for multi-functional integration and efficient transmission, thus hindering the further development and application of power and communication systems. Therefore, we propose a wire and cable with high-efficiency compressive strength. Utility Model Content

[0015] 1. This high-efficiency pressure-resistant cable achieves superior pressure resistance through a multi-layered structural design.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-5A high-efficiency pressure-resistant wire and cable includes a semiconductor 1, an insulation layer 2, an electromagnetic shielding layer 5, and an outer protective sleeve 7. The insulation layer 2 is sleeved on the semiconductor 1. The insulation layer 2 and the semiconductor 1 are inserted into the interior of a buffer filling layer 3. Multiple semiconductors 1 and insulation layers 2 are arranged in a ring inside the buffer filling layer 3. An inner protective sleeve 4 is sleeved on the outside of the buffer filling layer 3. An electromagnetic shielding layer 5 is sleeved on the outside of the inner protective sleeve 4. A pressure-resistant layer 6 is sleeved on the outside of the electromagnetic shielding layer 5. An outer protective sleeve 7 is sleeved on the outside of the pressure-resistant layer 6.

[0025] Furthermore, a semiconductor 1 is interspersed inside the insulating layer 2. The outer cylindrical surface of the insulating layer 2 is provided with multiple annular and equidistantly distributed honeycomb support blocks 10. The honeycomb support blocks 10 are hexagonal in shape, and buffer grooves 11 are formed inside the end face of the honeycomb support blocks 10. Their function is to provide insulation protection for the semiconductor 1, while using the high stability of the hexagonal honeycomb structure to evenly distribute the external pressure. The buffer grooves 11 absorb pressure energy through deformation, improve the pressure resistance of the insulating layer 2, ensure the stable transmission of current by the semiconductor 1, and avoid the risk of insulation layer damage and current leakage caused by pressure.

[0026] Furthermore, the buffer filling layer 3 has multiple ring-shaped mounting holes 12 inside, and an insulating layer 2 is inserted inside the mounting holes 12. The end face of the honeycomb support block 10 on the outer cylindrical surface of the insulating layer 2 fits tightly with the inner wall of the mounting hole 12, which can accurately position the insulating layer 2 and enhance its stability inside the cable. At the same time, the buffer filling layer 3 can absorb and buffer the pressure transmitted from the outside, further protecting the internal semiconductor 1 and the insulating layer 2, and realizing efficient utilization of the internal space of the cable and structural stability.

[0027] Furthermore, the outer cylindrical surface of the buffer filling layer 3 is provided with multiple hemispherical airbag pressure-resistant blocks 13. The airbag pressure-resistant blocks 13 are arranged in a ring and are evenly distributed on the outer cylindrical surface of the buffer filling layer 3. An inner protective sleeve 4 is sleeved on the outside of the buffer filling layer 3. The inner wall of the inner protective sleeve 4 is tightly fitted with the airbag pressure-resistant blocks 13. When the cable is subjected to external pressure, the gas in the airbag pressure-resistant blocks 13 is compressed. The pressure is absorbed by the compressibility of the gas and evenly dispersed to the buffer filling layer 3. The inner protective sleeve 4 stabilizes the buffer filling layer 3 and prevents it from shifting and deforming under pressure, playing a key buffer protection role and reducing the pressure impact on the internal structure of the cable.

[0028] Furthermore, an electromagnetic shielding layer 5 is fixedly fitted to the outer side of the inner protective sleeve 4. A metal wire mesh 9 is provided on the outer wall of the electromagnetic shielding layer 5. A pressure-resistant layer 6 is fitted to the outer side of the electromagnetic shielding layer 5. The metal wire mesh 9 is placed between the electromagnetic shielding layer 5 and the pressure-resistant layer 6. An outer protective sleeve 7 is fixedly fitted to the outer side of the pressure-resistant layer 6. The metal wire mesh 9 and the electromagnetic shielding layer 5 work together to intercept, reflect, and absorb electromagnetic signals and resist external electromagnetic interference. The pressure-resistant layer 6 provides high-strength support and withstands greater external pressure. The combination of the three ensures the accuracy of cable signal transmission and enhances the overall pressure resistance of the cable, achieving a unity of electromagnetic protection and pressure resistance functions.

[0029] Furthermore, the outer cylindrical surface of the outer protective sleeve 7 is provided with a spiral corrugated column 8. When the cable is under pressure, the pressure is dispersed and transmitted along the spiral direction through the spiral shape to avoid pressure concentration. At the same time, the corrugated structure increases the surface area and elasticity of the outer protective sleeve 7, generating greater deformation under pressure to absorb more energy, further improving the overall pressure resistance of the cable, protecting the internal structure, and extending the service life of the cable.

[0044] Working Principle: Semiconductor 1, as the core component of the cable for current transmission, bears the task of transmitting electrical energy. Insulation layer 2 is tightly fitted onto semiconductor 1, isolating the semiconductor from the outside environment and preventing current leakage and short circuits. The honeycomb support block 10 on the outer cylindrical surface of insulation layer 2 is hexagonal in shape and has a buffer groove 11 inside. On the one hand, the hexagonal structure has good stability and can effectively disperse pressure. The buffer groove 11 can deform under pressure, absorb pressure energy, and improve the pressure resistance of insulation layer 2. On the other hand, the honeycomb support block 10 fits tightly with the inner wall of the mounting hole 12 of the buffer filling layer 3, further enhancing the stability of insulation layer 2 inside the cable and ensuring current transmission. For stability and safety, the mounting holes 12 inside the buffer filling layer 3 provide installation space for the insulation layer 2 and the semiconductor 1. Multiple semiconductors 1 and insulation layers 2 are distributed in a ring inside, which can make full use of the internal space of the cable and achieve efficient power transmission. At the same time, the airbag pressure-resistant blocks 13 on the outer cylindrical surface of the buffer filling layer 3 are hemispherical and distributed in a ring at equal intervals. When the cable is subjected to external pressure, the gas inside the airbag pressure-resistant blocks 13 can be compressed. Through the compressibility of the gas, the pressure is absorbed and evenly distributed to the buffer filling layer 3, reducing the pressure on the internal structure of the cable and playing a buffer protection role. The inner protective sleeve 4 is tightly attached to the airbag pressure-resistant blocks 13 to stabilize the buffer filling layer 3. To prevent displacement and deformation under pressure, the metal mesh 9 on the outside of the electromagnetic shielding layer 5 works together with the electromagnetic shielding layer 5. The metal mesh 9 can effectively intercept and reflect electromagnetic signals, while the electromagnetic shielding layer 5 can absorb the remaining electromagnetic energy. Together, they block external electromagnetic interference, preventing it from affecting the current transmission within the cable and ensuring the accuracy and stability of the cable's signal transmission. The pressure-resistant layer 6, as a key structural layer for the cable to withstand pressure, works closely with the outer protective sleeve 7. The pressure-resistant layer 6 can withstand significant external pressure. The outer cylindrical surface of the outer protective sleeve 7 has spiral corrugated spiral columns 8. This spiral corrugated structure, when the cable is under pressure, It can disperse pressure through its own elastic deformation, and the spiral shape disperses pressure along the spiral direction, avoiding pressure concentration at a certain point. At the same time, the corrugated structure can increase the surface area and elasticity of the outer protective sleeve 7, generate greater deformation under pressure, absorb more pressure energy, and further improve the overall pressure resistance of the cable. Stable power transmission is achieved through semiconductor 1 and insulation layer 2. Electromagnetic interference is resisted by buffer filling layer 3, inner protective sleeve 4, electromagnetic shielding layer 5, and metal wire mesh 9. External pressure is resisted by pressure-resistant layer 6, outer protective sleeve 7, and corrugated spiral column 8. The various layers work together to ensure the stable and efficient operation of the cable in complex environments.
