Description

Technical Field

[0001] This utility model relates to the field of optical fiber and cable technology, specifically a corrosion-resistant optical fiber and cable. Background Technology

[0002] Fiber optic cables are most widely used in the field of communications. They enable long-distance, high-speed transmission of telephone, data, and image signals. Fiber optic cables offer faster transmission speeds, less signal attenuation, stronger anti-interference capabilities, wider transmission bandwidth, and higher reliability.

[0003] The prior art discloses patent application number "CN202320351645.4", which describes a water-drop-protected anti-aging optical cable. The cable includes an outer sheath, multiple optical fiber units disposed inside the outer sheath, and a central reinforcing core. Each optical fiber unit consists of multiple individual optical fibers and an outer sleeve. All optical fiber units are arranged in a ring around the central reinforcing core. The sleeve has an overall teardrop shape. The central reinforcing core includes a core body and several radial corners formed on the core body. The optical fiber units are arranged between the radial corners, with the arc-shaped ends of the sleeve facing outwards from the core body. A waterproof composite structure is also provided between the outer sheath and the optical fiber units. This waterproof composite structure includes a water-blocking tape layer, a glass fiber tape layer, and a silicone rubber coating arranged sequentially from the inside out.

[0004] This optical cable can only achieve anti-aging, but in actual use, because the outer surface of the optical fiber cable is exposed to the outside world and its structural design is relatively simple, its corrosion resistance is poor. After long-term use, the outer surface of the optical fiber cable is prone to damage, which affects the safety of the optical fiber cable during use and makes it inconvenient to use.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a polyethylene sheath to give the optical fiber cable excellent resistance and better corrosion resistance. Combined with the use of a nylon sheath and a fine steel wire armor layer, two protective layers can be formed on the outer layer of the optical fiber cable, enabling the optical fiber cable to resist the erosion in the external environment and improve the wear resistance of the optical fiber cable.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, a corrosion-resistant optical fiber cable includes a polyethylene sheath 2, a fine steel wire armor layer 4 fixedly connected inside the polyethylene sheath 2, a nylon sheath 5 fixedly installed on the outer surface of the polyethylene sheath 2, cable grease 6 fixedly connected inside the polyethylene sheath 2, and a water-blocking layer 7 fixedly provided inside the polyethylene sheath 2. The water-blocking layer 7 is made of polyacrylate material, which expands rapidly when it comes into contact with water to form a gel-like substance, effectively preventing water from penetrating, thereby achieving the purpose of water blocking and allowing the optical fiber cable to operate normally.

[0026] The fine steel wire armor layer 4 has a central reinforcing member 3 fixedly installed inside, and an array of second support blocks 14 fixedly connected inside. An array of optical fiber cable bodies 1 are fixedly installed inside the fine steel wire armor layer 4. The second support blocks 14 are used to position the optical fiber cable bodies 1. Through the setting of the fine steel wire armor layer 4, the fine steel wire armor layer 4 has good corrosion resistance and fatigue resistance, and can be used for a long time in harsh environments without easily rusting.

[0027] The fine steel wire armor layer 4 has an internal array of protrusions 8. Both ends of the protrusions 8 are slidably connected to telescopic clamps 9 for positioning the main body 1 of the optical fiber cable. A connecting spring 10 is fixedly connected between the telescopic clamps 9 and the protrusions 8.

[0028] The outer surface of the central reinforcing member 3 is arrayed with a first support block 13 for fixing the optical fiber cable body 1, and the outer surface of the central reinforcing member 3 is arrayed with a double-headed support seat 15 for fixing the optical fiber cable body 1.

[0029] A second embedded slot 88 is provided on one side of the first support block 13. The second embedded slot 88 is adapted to the optical fiber cable body 1. The outer surface of the optical fiber cable body 1 is engaged with one side of the first support block 13 through the second embedded slot 88.

[0030] The fine steel wire armor layer 4 has an internal array of rubber arc pads 11 connected to it. A connecting spring 12 is fixedly installed between the rubber arc pads 11 and the fine steel wire armor layer 4. The rubber arc pads 11 can elastically squeeze the telescopic clamp 9, allowing the telescopic clamp 9 to fit tightly against the optical fiber cable.

[0031] The second support block 14 has a first embedded slot 66 on one side. The first embedded slot 66 is adapted to the optical fiber cable body 1. The outer surface of the optical fiber cable body 1 is engaged with one side of the second support block 14 through the first embedded slot 66.

[0032] The working principle of the corrosion-resistant optical fiber cable provided by this utility model is as follows:

[0033] The polyethylene sheath 2 provides excellent durability and corrosion resistance to the optical fiber cable. Combined with the nylon sheath 5 and the fine steel wire armor layer 4, two protective layers are formed on the outer surface of the optical fiber cable, enabling it to resist corrosion from the external environment and improving its abrasion resistance. Then, the cable grease 6 and the water-blocking layer 7 prevent water penetration, providing waterproofing and moisture protection to ensure that the interior of the optical fiber cable is not affected by moisture. Finally, the central reinforcing member 3 and the double-headed support 15 at the central reinforcing member 3 can initially position the five main optical fiber cable bodies 1, enhancing the stability of the optical fiber cable.

[0034] The telescopic clamp 9, with connecting spring 10 installed at the protrusion 8, can be fitted and positioned against the outer surface of the optical fiber cable body 1. The elastic force of the connecting spring 10 allows the telescopic clamp 9 to elastically clamp the two ends of the optical fiber cable for initial fixation. Then, the first support block 13 at the central reinforcing member 3 and the second support block 14 at the thin steel wire armor layer 4 can be snapped and fixed to the other two ends of the optical fiber cable to ensure all-round fixation and stability. At the same time, the rubber arc pad 11 with connecting spring 2 12 can support the telescopic clamp 9, making the optical fiber cable more secure and stable, and enhancing its strength during use.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
