Description

Technical Field

[0001] The utility model relates to the technical field of optical cable equipment, in particular to an anti-ant type optical cable. Background Art

[0002] With the rapid development of science and technology in the 21st century, optical fiber, as a transmission medium, has been widely used in the field of information transmission due to its high security, reliability and excellent network performance. However, optical fiber also faces a series of challenges in the application process, one of which is the invasion of termites.

[0003] At present, there are two main types of termite-proof optical cable technologies on the market: physical armored type and chemical termite-proof type.

[0004] Physically armored anti-ant optical cables add an armored anti-ant layer during the production process of the optical cable. Generally, thermoplastic polyurethane elastomer rubber and other wear-resistant and fatigue-resistant materials are used. The armoring process is complicated and faces the risk of scrapping if quality problems occur.

[0005] Chemical anti-ant type anti-ant optical cable adds anti-ant agent to the polyethylene sheath material, which simplifies the product process and reduces the cost, but there are problems with the low toxicity and pungent odor of the anti-ant agent, which causes great inconvenience to production operators and construction workers. For this reason, we propose anti-ant type optical cable. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies of the prior art, the utility model provides an anti-ant type optical cable, which overcomes the deficiencies of the prior art, has a reasonable design, a compact structure, and solves the problems raised in the background technology.

[0008] (II) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] Anti-ant optical cable, including:

[0011] An optical cable having a jacket comprised of polyaryletherketone and having at least one central strength member and a loose tube;

[0012] Among them, a water-blocking material is wrapped between the central reinforcement and the loose sleeve;

[0013] There is at least one optical fiber in the loose tube and the loose tube is wrapped by a water-blocking material.

[0014] Preferably, the loose tube has at least two optical fibers, and the space between the two optical fibers is filled and wrapped with water-blocking fiber paste.

[0015] Preferably, the device further comprises at least one filling rope, wherein the filling rope and the loose tube are twisted on the outer surface of the central reinforcement member.

[0020] Preferably, the central reinforcement is made of glass fiber reinforced plastic.

[0021] (III) Beneficial effects

[0022] The utility model provides an anti-ant type optical cable, which has the following beneficial effects:

[0023] 1. Polyetherketoneketone PEKK has high chemical stability and is not easy to decompose. Therefore, under normal use temperature and conditions, it will not release toxic gases and irritating odors, ensuring the safety of production operators and construction laying personnel.

[0024] 2. The polyetherketoneketone PEKK used is a type of polyaryletherketone, which has excellent heat resistance, water resistance, solvent resistance, electrical insulation, high fatigue strength, excellent wear resistance, high creep resistance, and polyaryletherketone does not require the addition of flame retardants. It is flame retardant in itself and can meet other performance requirements of optical cables.

[0025] 3. Optimize product structure, simplify production process, and improve production efficiency.

[0026] 4. Polyetherketoneketone PEKK has an excellent price, which is slightly more expensive than polyethylene; it is much cheaper than the thermoplastic polyurethane elastomer rubber-type wear-resistant and fatigue-resistant materials used in the armor layer.

[0027] 5. Thanks to its more stable chemical and physical properties, the optical cable has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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] Refer to the attached Figure 1-2 , ant-proof optical cable, including:

[0033] An optical cable having a sheath 1 consisting of polyaryletherketone and having at least one central strength member 6 and a loose tube 7;

[0034] Wherein, a water-blocking material is wrapped between the central reinforcement member 6 and the loose tube 7;

[0035] Therein, at least one optical fiber 5 is located in the loose tube 7 and is wrapped by a water-blocking material.

[0036] In this embodiment, the loose tube 7 has at least two optical fibers 5 , and the space between the two optical fibers 5 is filled and wrapped with a water-blocking fiber paste 4 .

[0038] In this embodiment, the sheath 1 is made of polyetherketoneketone, and the material of the sheath is polyetherketoneketone PEKK, a type of polyaryletherketone. Polyetherketoneketone PEKK, which has better wear resistance, higher fatigue strength, higher creep resistance and other indicators than polyethylene, is used instead of polyethylene plastic, which can effectively prevent termites from corroding the flame-retardant optical cable.

[0039] In this embodiment, the water-blocking material in the sheath 1 is a water-blocking cable paste 2, which is used to protect the entire optical cable structure from moisture intrusion.

[0040] In this embodiment, the water-blocking material in the loose tube 7 is a water-blocking fiber paste 4 , which is used to maintain the softness and bending properties of the optical fiber in the loose tube 7 .

[0042] In this embodiment, the central reinforcement member 6 is made of glass fiber reinforced plastic.

[0043] Processing process:

[0044] S1. Fiber coloring: Color the bare fiber to coat the surface of the fiber 5 with a uniform and firm color mark for easy identification.

[0045] S2. Secondary coating: coat the optical fiber 5 for the second time, so that the optical fiber is in a loose plastic tube, reducing the impact of the outside world on the optical fiber 5, and adding water-blocking fiber paste 2 to ensure the water-blocking performance of the optical cable.

[0046] S3.SZ twisting: The central reinforcement is made of metal material or non-metallic material, glass fiber reinforced plastic GFRP is used for non-metallic materials, and high-strength steel wire is used for metal to enhance the tensile performance of the optical cable; the central reinforcement is twisted around by secondary plastic loose tube 7 and possible filling rope 3, and filled with water-blocking cable paste 2 to ensure the water-blocking performance of the optical cable.

[0047] S4. Sheath extrusion: a layer of polyetherketoneketone PEKK sheath 1 is extruded outside the twisted components. The nominal thickness of the sheath 1 is 2.0 mm, and the thinnest thickness is 1.6 mm. It is used to protect the optical cable and prevent ants.
