Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a novel water-resistant and high-pressure-resistant computer cable. Background Technology

[0002] With the development of industrial technology, humanity is increasingly exploiting Earth's extreme environments. The significance of high-voltage-resistant computer cables lies in providing a solution capable of stably transmitting data and power even in extreme conditions.

[0003] The technological background of high-pressure-resistant computer cables can be traced back to the 1980s. With the continuous advancement of science and technology, especially the rapid development in fields such as military, aerospace, deep-sea exploration, and nuclear industry, higher requirements have been placed on the pressure resistance of cables.

[0004] Over the past few decades, cable manufacturers have continuously developed new materials and technologies to improve the compressive strength of cables. For example, in terms of material selection, high-molecular-weight materials with excellent mechanical strength and chemical stability are chosen for the insulation layer. These materials can maintain stable performance under high-voltage conditions, ensuring the normal operation of the cable.

[0005] Furthermore, with the rapid development of electronic technology, cable shielding technology has also been significantly improved. Modern high-voltage-resistant computer cables, through the design of more scientifically sound shielding structures, effectively resist external electromagnetic interference, ensuring the stability and reliability of signal transmission. According to relevant data, cables using advanced shielding technology can reduce signal attenuation to less than one-tenth of the original rate under high-voltage environments.

[0006] Regarding the outer sheath of cables, the rapid development of new materials has led to the emergence of more high-voltage resistant materials that can meet the needs of extreme environments such as deep-sea exploration. These materials not only have excellent compressive strength but also good corrosion resistance and temperature resistance, enabling them to operate for extended periods in harsh environments without failure.

[0007] However, existing computer cables have many shortcomings, such as poor water resistance and low pressure resistance, which urgently need to be optimized and improved. Therefore, we propose a new type of water-resistant and high-pressure-resistant computer cable. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a new type of water-blocking and high-pressure-resistant computer cable, which has the characteristics of wear resistance, high pressure resistance, good water-blocking performance, strong climate adaptability, and excellent shielding performance.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A novel water-blocking and high-pressure-resistant computer cable is designed, comprising seven cable cores. The seven cable cores are collectively wrapped with a water-blocking tape. A braided reinforcing layer is provided outside the water-blocking tape. A composite wrapping layer is provided outside the braided reinforcing layer. An inner sheath is provided outside the composite wrapping layer. An interlocking armor layer is wrapped outside the inner sheath. An outer sheath is provided outside the interlocking armor layer. Each cable core includes a conductor, an insulation layer, a filler layer, and a core shielding layer. There are three conductors, each with an insulation layer on its outer side. The three insulation layers are collectively wrapped with a core shielding layer, and the gap between the core shielding layer and the insulation layer is filled with a filler layer.

[0011] Preferably, the conductor is a type 5 soft copper conductor, which is stranded together.

[0012] Preferably, the insulating layer is made of polyethylene.

[0013] Preferably, the filling layer is made of semi-conductive resistive water filling rope.

[0014] Preferably, both the wire core shielding layer and the cable core braided reinforcement layer are made of soft copper wire.

[0015] Preferably, the water-blocking tape is a single-sided laminated water-blocking tape.

[0016] Preferably, the composite wrapping layer is made of electrolytic copper foil strip.

[0017] Preferably, the inner protective layer is made of polyethylene.

[0018] Preferably, the interlocking armor layer is wrapped with copper strip.

[0019] Preferably, the outer protective layer is made of polyurethane sheath material.

[0020] This utility model proposes a novel water-blocking, high-pressure-resistant computer cable with the following advantages: The core shielding layer and braided reinforcement layer ensure the overall anti-interference capability of the product; the filler layer effectively shields against corrosion from harsh external environments while improving the cable's water-blocking performance; the water-blocking tape ensures water-blocking performance; and the composite wrapping layer enhances the cable's overall anti-interference capability and mechanical strength, while also exhibiting excellent chemical stability. The inner sheath provides the cable with good mechanical properties and water-blocking capability, the interlocking armor layer improves the cable's overall mechanical strength and anti-interference capability, and the outer sheath achieves high stability and high pressure resistance. This utility model features wear resistance, high pressure resistance, good water-blocking performance, strong climate adaptability, and excellent shielding performance.

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 scope of protection of the present utility model.

[0026] Reference Figure 1 A novel water-blocking and high-pressure-resistant computer cable includes seven cable cores. The seven cable cores are collectively wrapped with a water-blocking tape 5. A braided reinforcing layer 6 is located outside the water-blocking tape 5. A composite wrapping layer 7 is located outside the braided reinforcing layer 6. An inner sheath 8 is located outside the composite wrapping layer 7. An interlocking armor layer 9 is wrapped outside the inner sheath 8. An outer sheath 10 is located outside the interlocking armor layer 9. Each cable core includes a conductor 1, an insulation layer 2, a filler layer 3, and a core shielding layer 4. There are three conductors 1, and an insulation layer 2 is located outside each conductor 1. The three insulation layers 2 are collectively wrapped with the core shielding layer 4, and the gap between the core shielding layer 4 and the insulation layer 2 is filled with a filler layer 3.

[0027] Conductor 1 is made of Category 5 soft copper conductor and is stranded. This effectively reduces the wire diameter, making the cable structure more compact.

[0028] Insulation layer 2 is made of polyethylene. It possesses excellent electrical insulation properties, chemical resistance, abrasion resistance, and relatively low dielectric constant and loss factor. Furthermore, polyethylene exhibits good processability, high mechanical strength and tensile strength, and excellent low-temperature resistance.

[0029] Filler layer 3 uses semi-conductive resistive water-filled rope. Its main function is to protect the conductor and keep the cable round. It can effectively shield against corrosion from harsh external environmental factors, while also improving the cable's water resistance.

[0030] Both the conductor shielding layer 4 and the cable core braided reinforcement layer 6 are made of soft copper wire. This improves the overall mechanical strength of the cable, reduces electromagnetic radiation, and enhances the cable's anti-interference capability.

[0031] The water-blocking tape 5 uses a single-sided laminated water-blocking tape to ensure water-blocking performance.

[0032] The composite wrapping layer 7 is made of electrolytic copper foil. This improves the overall anti-interference capability and mechanical strength of the cable, and also provides excellent chemical stability.

[0033] The inner sheath 8 is made of polyethylene. It possesses excellent electrical insulation properties, chemical corrosion resistance, abrasion resistance, and relatively low dielectric constant and loss factor. Furthermore, polyethylene exhibits good processability, high mechanical strength and tensile strength, and excellent low-temperature resistance. Moreover, polyethylene as an inner sheath also has high water-blocking capability.

[0034] The interlocking armor layer 9 is wrapped with copper tape. This provides additional mechanical protection, enhancing the cable's tensile and compressive strength; improving the cable's electromagnetic interference resistance and ensuring signal transmission stability; effectively preventing damage from the external environment; during laying, the armor layer helps the cable maintain its shape, reducing bending and kinking; furthermore, the copper tape interlocking armor also helps dissipate heat, increasing its current carrying capacity.

[0035] The outer sheath 10 is made of polyurethane. It has excellent compressive strength, as well as good corrosion resistance and temperature resistance, and can work for a long time in harsh environments without failure.
