Description

Technical Field

[0001] This utility model relates to a communication cable, specifically a friction-resistant and flame-retardant optoelectronic composite cable for indoor and outdoor applications. Background Technology

[0002] Optical fiber cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. However, the internal materials of optical fiber cables are relatively fragile and often require additional plastic tubing for protection.

[0003] In interior decoration, traditional fiber optic cable installation methods suffer from problems such as large duct space requirements, poor abrasion resistance and flame retardancy, and mixed installation of fiber optic and electrical cables, which increase the installation and usage costs of fiber optic cables. Therefore, designing a friction-resistant and flame-retardant fiber optic composite cable for indoor and outdoor entry is of great significance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and provide an indoor and outdoor friction-resistant and flame-retardant optical composite cable. The optical cable should have the advantages of friction resistance and flame retardancy, and the combination with the cable should have a high degree of integration and excellent mechanical properties.

[0005] The technical solution of this utility model is:

[0006] A friction-resistant and flame-retardant optical-electric composite cable for indoor and outdoor applications, characterized in that it includes optical units arranged side by side with electrical units, an outer sheath that is circular and covers the optical units and electrical units, and a mesh filler that fills the gaps inside the outer sheath.

[0007] The optical unit includes an optical fiber, reinforcing members symmetrically disposed on both sides of the optical fiber, a butterfly-shaped sheath covering the optical fiber and the reinforcing members, an inner sheath of the optical unit covering the butterfly-shaped sheath, and a non-metallic reinforcing member filling the gap between the butterfly-shaped sheath and the inner sheath of the optical unit.

[0008] The electrical unit includes several copper conductors, a power line sheath covering the copper conductors, and an inner sheath covering the electrical unit.

[0009] The mesh filler material is PP mesh filler rope.

[0010] The copper conductor is a multi-stranded copper wire.

[0011] Both the inner sheath of the optical unit and the inner sheath of the electrical unit are made of low-smoke halogen-free flame-retardant polyolefin or flame-retardant polyvinyl chloride.

[0012] The beneficial effects of this utility model are:

[0013] 1. Integrating the optoelectronic unit into a low-friction, high-flame-retardant composite cable reduces the floor space required, thereby lowering construction costs.

[0014] 2. This composite cable features inner and outer double sheaths, eliminating the need for repeated conduit insertion and reducing construction difficulty.

[0015] 3. After the outer sheath is stripped, the photoelectric units can be branched into their respective socket connector boxes, avoiding the problem of damage to the photoelectric circuits caused by improper operation during cable construction. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] Figure 1 The indoor / outdoor drop-in resistant, flame-retardant optical-electric composite cable shown includes an optical unit 1, an electrical unit 2, a mesh filler 3, and an outer sheath 4. Figure 1 As shown in the cross-section of the optical-electric composite cable, the optical unit and the electrical unit are arranged in parallel. The outer sheath is circular and covers the remaining gaps after the optical unit and the electrical unit. The mesh filler is used to buffer and dampen the shock.

[0023] The mesh filler is made of PP mesh filler rope (a common filler material on the market), used to fill the gap between the optoelectronic unit and the outer sheath, which can improve the roundness and flexibility of the composite cable.

[0024] like Figure 2As shown, the optical unit includes optical fiber 1-1, reinforcing member 1-2, butterfly cable sheath 1-3, non-metallic reinforcing member 1-4, and inner sheath of the optical unit 1-5.

[0025] The optical fiber is either bare or dyed, and can be either single-mode or multimode.

[0026] Two parallel and symmetrically arranged reinforcing members are provided on both sides of the optical fiber. The reinforcing members are made of metal or non-metal and can provide good tensile strength for the optical fiber.

[0027] The butterfly cable sheath covers the reinforcing member and the optical fiber, thus forming a whole (which can be called a butterfly optical cable); the butterfly cable sheath material is low smoke halogen-free flame-retardant polyolefin or flame-retardant polyvinyl chloride, which can protect the optical fiber and facilitate splicing at both ends of the optical cable.

[0028] The outer side of the butterfly cable sheath is provided with several non-metallic reinforcing members (no less than two); the non-metallic reinforcing members are aramid yarn or water-blocking aramid yarn, which provide the optical cable with high tensile strength, easy bending flexibility and water-proof function, and fill the gap between the butterfly cable sheath and the inner sheath of the optical unit, thus playing the role of rounding the optical unit.

[0029] The inner sheath of the optical unit is circular, covering the butterfly cable sheath and non-metallic reinforcing members. The material of the optical unit sheath is low-smoke halogen-free flame-retardant polyolefin or flame-retardant polyvinyl chloride; the optical unit sheath protects the optical fiber and facilitates the branching of the optical cable at both ends into the junction box slot; the inner sheath of the optical unit provides pressure resistance and abrasion resistance.

[0030] like Figure 3 As shown, the electrical unit includes a copper conductor 2-1, a power cord sheath 2-2, and an inner sheath 2-3.

[0031] The copper conductor is a multi-stranded copper wire, and the power cord sheath wraps around the copper conductor to form a power cord.

[0032] The inner sheath of the electrical unit is circular, covering three conductor power lines. The copper conductors are used for household power transmission; the power line sheath is an insulator to prevent leakage; the inner sheath provides multiple layers of protection for the three power lines, offering pressure resistance and abrasion resistance.

[0033] The outer sheath material is a low-friction, low-smoke, halogen-free, and highly flame-retardant sheath material; it protects the optoelectronic unit, giving the optoelectronic composite cable advantages such as low coefficient of friction, easy to insert into tubes, wear-resistant and tear-resistant, high temperature resistant and environmentally friendly.

[0034] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
