Description

Technical Field

[0001] The utility model relates to the field of optical cables, and in particular to a freeze-proof and wear-resistant flame-retardant optical cable. Background Art

[0002] With the rapid development of communication technology, optical cables, as an important carrier of information transmission, are increasingly widely used. However, in actual use, existing optical cable technology has some shortcomings.

[0003] In cold environments, traditional optical cables have limited anti-freezing capabilities and are easily affected by low temperatures and freeze, resulting in signal transmission interruption or damage, affecting the stability and reliability of communications.

[0004] At the same time, existing optical cables also have issues with wear resistance. During installation and use, optical cables are often subject to friction and abrasion. Traditional optical cables lack sufficient wear resistance, which can easily lead to damage to the cable sheath, affecting its internal structure and signal transmission quality.

[0005] Fire resistance is also a key issue for optical cables. In some special environments or fire emergencies, traditional optical cables have weak fire resistance and are easily spread by fire, causing serious damage and even posing greater safety risks.

[0006] Furthermore, the thermal insulation performance of traditional optical cables needs to be improved. External heat can easily affect the interior of the optical cable, potentially causing problems with signal transmission.

[0007] Finally, existing optical cables also have certain shortcomings in terms of structural strength and external protection. They may not be able to withstand significant external pressure and tensile forces, and are prone to deformation or damage. Furthermore, their ability to protect against external impact is insufficient, making them susceptible to damage from external factors.

[0008] In summary, existing optical cable technology has many shortcomings in terms of antifreeze, wear resistance, flame retardancy, thermal insulation, structural strength, and external protection, and cannot meet the high performance requirements of modern communications. Some of these shortcomings still need to be improved during use, so we have made improvements to this by proposing a flame-retardant optical cable that is antifreeze and wear-resistant.

It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Example 1: Please refer to Figure 1-Figure 5 A freeze-proof and wear-resistant flame-retardant optical cable comprises an optical cable core 1, the outer surface of the optical cable core 1 is provided with a cable core sleeve 101, the outer surface of the cable core sleeve 101 is coated with a polyethylene antifreeze coating 2, the outer surface of the polyethylene antifreeze coating 2 is provided with a ceramic fiber sleeve 3, the outer surface of the ceramic fiber sleeve 3 is provided with a carbon fiber sleeve 301, the outer surface of the carbon fiber sleeve 301 is provided with a wear-resistant sleeve 4, the outer surface of the wear-resistant sleeve 4 is provided with a wear-resistant rubber layer 401, the interior of the carbon fiber sleeve 301 is provided with a fireproof sleeve 5, the inner layer of the fireproof sleeve 5 is provided with an insulating carbon layer 501, and a fireproof coating 502 is provided under the insulating carbon layer 501.

[0035] An elliptical protective sheath 6 is installed outside the ceramic fiber sheath 3. A buffer cavity 601 is provided between the elliptical protective sheath 6 and the ceramic fiber sheath 3. The buffer cavity 601 is 2 mm wide. The diameter of the optical cable core 1 is 5 mm. The semi-major axis of the elliptical protective sheath 6 is 10 mm, and the semi-minor axis of the elliptical protective sheath 6 is 8 mm. The wear-resistant rubber layer 401 is 1 mm thick. The thermal insulation carbon layer 501 is 0.5 mm thick. The fire-retardant coating 502 is 0.3 mm thick.

[0036] The antifreeze and wear-resistant flame-retardant optical cable operates as follows: The optical cable core 1, the core component for transmitting optical signals, is protected by a cable core jacket 101. The polyethylene antifreeze coating 2 applied to the cable core jacket 101 effectively prevents the cable from freezing in low-temperature environments, maintaining its normal operating performance.

[0037] The ceramic fiber sheath 3 outside the polyethylene antifreeze coating 2 has good thermal insulation performance, which can reduce the impact of external heat on the inside of the optical cable, and can also improve the fire resistance of the optical cable to a certain extent.

[0038] The carbon fiber sheath 301 outside the ceramic fiber sheath 3 has high strength and wear resistance, and can protect the optical cable from external mechanical damage while enhancing the overall structural strength of the optical cable.

[0039] The wear-resistant sleeve 4 outside the carbon fiber sleeve 301 further improves the wear resistance of the optical cable, while the wear-resistant rubber layer 401 outside the wear-resistant sleeve 4 can better resist external friction and wear, thereby extending the service life of the optical cable.

[0040] The fireproof sleeve 5, insulating carbon layer 501, and fireproof coating 502 within the carbon fiber sheath 301 together form a flame-retardant system. The fireproof sleeve 5 prevents the spread of flames, the insulating carbon layer 501 effectively isolates heat, reducing its transfer into the cable, and the fireproof coating 502 acts as a flame retardant to prevent further spread of fire.

[0041] The elliptical protective sheath 6 outside the ceramic fiber sheath 3 can provide additional protection for the optical cable, reducing direct impact of external objects on the optical cable. The buffer cavity 601 between the elliptical protective sheath 6 and the ceramic fiber sheath 3 can absorb and buffer external impact forces, reducing damage to the internal structure of the optical cable.

[0042] When the optical cable is exposed to low temperatures, the polyethylene antifreeze coating 2 prevents the cable from freezing. When the cable is subject to friction or abrasion, the wear-resistant sleeve 4 and wear-resistant rubber layer 401 provide protection. When exposed to fire, the fireproof sleeve 5, thermal insulation carbon layer 501, and fireproof coating 502 work together to achieve flame retardancy. The elliptical protective sleeve 6 and buffer cavity 601 protect the cable from external impacts. Through the synergistic effect of these structures and materials, the optical cable achieves antifreeze, wear resistance, and flame retardancy, ensuring safe and reliable operation in a variety of complex environments.

[0043] Example 2: A flame-retardant optical cable that is freeze-proof and wear-resistant. The diameter of the optical cable core 1 is 5 mm, and the thickness of the cable core sleeve 101 on the outer surface is 1 mm. The polyethylene antifreeze coating 2 on the outer surface of the cable core sleeve 101 is 2 mm thick to provide good freeze-proof performance. The ceramic fiber sleeve 3 provided on the outer surface of the polyethylene antifreeze coating 2 is 1.5 mm thick to enhance the thermal insulation performance of the optical cable. The carbon fiber sleeve 301 provided on the outer surface of the ceramic fiber sleeve 3 is 1 mm thick to improve the strength and wear resistance of the optical cable. The wear-resistant sleeve 4 provided on the outer surface of the carbon fiber sleeve 301 is 1.2 mm thick to further enhance the wear resistance. The wear-resistant rubber layer 401 provided on the outer surface of the wear-resistant sleeve 4 is 1 mm thick to protect the optical cable from external wear. The fireproof sleeve 5 inside the carbon fiber sleeve 301 is 0.8 mm thick, the heat-insulating carbon layer 501 provided on the inner layer of the fireproof sleeve 5 is 0.5 mm thick, and the fireproof coating 502 below is 0.3 mm thick, which together achieve a good flame-retardant effect. An elliptical protective sleeve 6 with a major semi-axis of 10 mm and a minor semi-axis of 8 mm is arranged outside the ceramic fiber sleeve 3. The buffer cavity 601 between the elliptical protective sleeve 6 and the ceramic fiber sleeve 3 has a width of 2 mm, which can effectively buffer external impact force.

[0044] The working process of the freeze-proof and wear-resistant flame-retardant optical cable is as follows: Signal transmission: The optical signal is transmitted in the optical cable core 1. As the core part of signal transmission, the optical cable core 1 is responsible for transmitting information from one end to the other.

[0045] Internal protection: A cable core sleeve 101 is provided on the outer surface of the optical cable core 1 to provide preliminary protection for the optical cable core 1 and prevent it from being directly damaged.

[0046] Antifreeze function: The polyethylene antifreeze coating 2 on the outer surface of the cable core sleeve 101 functions in low-temperature environments. When the optical cable is in a cold environment, the polyethylene antifreeze coating 2 prevents moisture from freezing on the cable surface, ensuring the normal operation of the cable and avoiding signal transmission interruption or cable damage caused by freezing.

[0047] Thermal insulation and fire prevention: The ceramic fiber sheath 3 outside the polyethylene antifreeze coating 2 has excellent thermal insulation properties, which can reduce the impact of external heat on the interior of the optical cable. At the same time, the ceramic fiber sheath 3 also has certain fire resistance properties, which can slow the spread of fire to a certain extent.

[0048] Reinforced Structure and Wear Resistance: The carbon fiber sheath 301 outside the ceramic fiber sheath 3 provides high strength and wear resistance, protecting the cable from external mechanical damage. The wear-resistant sheath 4 outside the carbon fiber sheath 301 further improves the cable's wear resistance, while the wear-resistant rubber layer 401 outside the wear-resistant sheath 4 enhances the cable's resistance to external friction and abrasion.

[0049] Flame retardant protection: The fireproof sleeve 5, thermal insulation carbon layer 501, and fireproof coating 502 within the carbon fiber sleeve 301 form a flame retardant system. In the event of a fire, the fireproof sleeve 5 primarily prevents the spread of flames; the thermal insulation carbon layer 501 effectively isolates heat, reducing its transfer into the cable. The fireproof coating 502 acts as a flame retardant, preventing further spread and protecting the cable's internal structure and signal transmission from being severely affected by the fire.

[0050] External Protection: An elliptical protective sheath 6 is installed outside the ceramic fiber sheath 3, providing additional physical protection for the cable and reducing direct impact from external objects. A buffer cavity 601 between the elliptical protective sheath 6 and the ceramic fiber sheath 3 absorbs and cushions external impact forces, further minimizing damage to the cable's internal structure. When the cable is impacted by external forces, the buffer cavity 601 deforms to absorb energy, mitigating the impact on the cable's interior, thereby protecting the cable's integrity and maintaining stable signal transmission.

[0051] In summary, the antifreeze and wear-resistant flame-retardant optical cable can effectively cope with various adverse factors such as low temperature, friction, wear and fire during signal transmission through the synergistic effect of various parts, ensuring the safe and reliable operation of the optical cable.
