Description

Technical Field

[0001] The present application belongs to the technical field of composite optical cables, and in particular relates to a composite optical cable with anti-interference function. Background Art

[0002] Composite optical cable refers to a new type of access method that is suitable for use as a transmission line in broadband access network systems. It integrates optical fiber and power transmission copper wire into one, and can solve the problems of broadband access, equipment power consumption, and signal transmission.

[0003] The internal structure of the composite optical cable is relatively complex, so repair and maintenance are more troublesome. The later use needs to be considered during the production and manufacturing process, so one-step molding is required. Among the composite optical cables currently available, it has the advantages of strong wear resistance and corrosion resistance. However, with the development of science and technology, the previous composite optical cables have highlighted their shortcomings in anti-interference, so they are often interfered with by external equipment and cannot achieve the ideal transmission efficiency.

[0004] To this end, we propose a composite optical cable with anti-interference function to solve the above problems. Utility Model Content

[0005] The purpose of this application is to solve the problem in the prior art that optical cables have shortcomings in anti-interference and often cannot achieve ideal transmission efficiency, and to propose a composite optical cable with anti-interference function.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A composite optical cable with an anti-interference function includes a metal reinforcement member, two filling ropes are arranged on the outside of the metal reinforcement member, two copper coils are arranged on the outside of the metal reinforcement member, an insulating layer is arranged on the outside of each copper coil, and the inner wall of each insulating layer is in contact with the outer surface of the copper coil; four optical fibers are arranged on the outside of the metal reinforcement member, the outer surfaces of the four optical fibers are commonly fixedly connected with a fiber paste, a loose tube is arranged on the outside of the fiber paste, the inner wall of the loose tube is in contact with the outer surface of the fiber paste; a filler is arranged on the outside of the metal reinforcement member, and the inner wall of the filler is in contact with the outer surfaces of the metal reinforcement member, the filling rope, the insulating layer and the loose tube respectively.

[0008] Preferably, an inner sheath is provided on the outer side of the filler, and the inner wall of the inner sheath is in contact with the outer surface of the filler.

[0009] Preferably, an anaerobic layer is provided on the outer side of the inner sheath, and the inner wall of the anaerobic layer is in contact with the outer surface of the inner sheath.

[0013] In summary, the technical effects and advantages of this application are:

[0014] By arranging metal reinforcements, filling ropes, insulation layers, copper coils, loose tubes, fiber paste, optical fibers and fillers in coordination with each other, the optical cable has strong anti-interference performance. The metal reinforcements can stabilize the overall internal direction of the optical cable, making it difficult for the optical cable to bend too much during transportation or installation, thereby playing a role of internal support. The filling ropes are used to fill the gaps in the loose tube optical fiber strands. The copper coils and insulation layers cooperate with each other to provide power support. The optical fiber is made of non-metallic quartz dielectric material, which is an insulator, not afraid of lightning and high voltage, and not affected by electromagnetic interference. The use of fiber paste can prevent moisture erosion in the air and alleviate the influence of external mechanical forces such as vibration, impact, and bending on the optical fiber. Finally, the loose tube is used to protect the optical fiber core, cladding and coating, so that the optical cable has strong comprehensive capabilities and can effectively achieve anti-interference effects.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A composite optical cable with anti-interference function includes a metal reinforcement 1, two filling ropes 2 are arranged on the outside of the metal reinforcement 1, two copper coils 4 are arranged on the outside of the metal reinforcement 1, an insulating layer 3 is arranged on the outside of each copper coil 4, and the inner wall of each insulating layer 3 is in contact with the outer surface of the copper coil 4; four optical fibers 7 are arranged on the outside of the metal reinforcement 1, and the outer surfaces of the four optical fibers 7 are fixedly connected with a fiber paste 6; a loose tube 5 is arranged on the outside of the fiber paste 6, and the inner wall of the loose tube 5 is in contact with the outer surface of the fiber paste 6; a filler 8 is arranged on the outside of the metal reinforcement 1, and the inner wall of the filler 8 is in contact with the outer surfaces of the metal reinforcement 1, the filling rope 2, the insulating layer 3 and the loose tube 5 respectively.

[0022] An inner sheath 9 is provided on the outside of the filler 8, and the inner wall of the inner sheath 9 is in contact with the outer surface of the filler 8. The inner sheath 9 is a protective covering layer wrapped around the cable insulation to prevent the insulation layer 3 from moisture, mechanical damage, light and chemically corrosive media, etc., and at the same time, short-circuit current can also flow through.

[0023] An anaerobic layer 10 is provided on the outside of the inner sheath 9. The inner wall of the anaerobic layer 10 is in contact with the outer surface of the inner sheath 9. The anaerobic layer 10 isolates the insulating organic matter from the outside air, and finally makes the cable self-extinguishing, thereby greatly improving the flame retardant level, which can reach Class A flame retardant level.

[0024] The outer surface of the anaerobic layer 10 is fixedly connected with a shaped steel wire layer 11, and the inner wall of the shaped steel wire layer 11 is fixedly connected with a plurality of steel wire strips 12. The shaped steel wire layer 11 is used to fix and limit the plurality of steel wire strips 12 to ensure the stability of the steel wire strips 12. The steel wire strips 12 can be used to enhance the overall strength and compression resistance of the optical cable.

[0025] An outer sheath 13 is provided on the outside of the shaped steel wire layer 11. The inner wall of the outer sheath 13 contacts the outer surface of the shaped steel wire layer 11. The outer sheath 13 protects the most important barrier for the safety of the internal structure and protects the cable from mechanical damage during and after installation.

[0026] A disassembly rope 14 is provided inside the filler 8, and the outer surface of the disassembly rope 14 contacts the inner wall of the filler 8. The disassembly rope 14 facilitates the easy separation of the optical cable when it is disassembled and scrapped later, thereby facilitating disassembly and recycling.

[0027] The working principle of the utility model is as follows: when in use, the metal reinforcement 1 is first used to stabilize the overall internal direction of the optical cable, making it difficult for the optical cable to bend too much during transportation or installation, thereby playing a role of internal support; the filling rope 2 is used to fill the vacancy in the loose-tube optical fiber 7 strand layer; the copper coil 4 and the insulating layer 3 cooperate with each other to provide power support; the optical fiber 7 is made of non-metallic quartz dielectric material, which is an insulator, not afraid of lightning and high voltage, and not subject to electromagnetic interference; the fiber paste 6 is used in conjunction with the fiber grease 6 to prevent moisture erosion in the air and alleviate the influence of external mechanical forces such as vibration, impact, and bending on the optical fiber 7; finally, the loose tube 5 is used to protect the core, cladding and coating of the optical fiber 7; the filler 8 is used to fix the internal cables in position to avoid mutual contact;

[0028] The inner sheath 9 is a protective covering layer wrapped around the cable insulation to prevent the insulating layer 3 from moisture, mechanical damage, light and chemical corrosive media, etc., and can also allow short-circuit current to flow through. The anaerobic layer 10 is used to isolate the insulating organic matter from the contact with the outside air, and ultimately the cable can achieve the purpose of self-extinguishing, thereby greatly improving the flame retardant level, which can reach Class A flame retardant level. The shaped steel wire layer 11 is used to fix and limit several steel wire strips 12 to ensure the stability of the steel wire strips 12. The steel wire strips 12 can enhance the overall strength and compression resistance of the optical cable. The outer sheath 13 is used to protect the most important barrier for the safety of the internal structure, protecting the cable from mechanical damage during and after installation. The disassembly rope 14 is used to easily separate the optical cable when it is disassembled and scrapped in the later stage, which plays a role in facilitating disassembly and recycling, so that the optical cable has a strong comprehensive ability and can effectively achieve the anti-interference effect.
