Description

Technical Field

[0001] The present disclosure relates to the field of cable technology, and in particular to a composite digital cable. Background Art

[0002] In communication cables, according to the different media, communication cables can be divided into optical cables with optical fiber as the transmission medium and copper cables with copper wire as the transmission medium. Optical fiber uses the principle of total reflection of light for data transmission, and has the advantages of large bandwidth, low loss, and long transmission distance. However, the material of optical fiber is glass fiber, which is an electrical insulator and cannot support active Ethernet (Power Over Ethernet, referred to as POE) power supply. Copper wire uses metal as the transmission medium and the principle of electromagnetic waves for data transmission. It can transmit both data signals and power signals, but there will be thermal effects during the transmission process, so the loss is large, which is not suitable for long-distance data transmission. In addition, it is clearly required in the network integrated wiring specification that the total length of the twisted pair link cannot exceed 100 meters. Utility Model Content

[0030] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0032] Specifically, in one embodiment, the reinforcement member 14 is a high-strength phosphated steel wire. In this embodiment, the protective layer 21 and the sheath layer 3 are made of the same material, and there are a variety of materials to choose from, including but not limited to at least one of polyvinyl chloride, polyethylene, glass fiber reinforced plastic material, low-smoke halogen-free material, polyurethane and thermoplastic polyurethane to protect the internal structure of the optical cable assembly 1 and the signal transmission cable assembly 2. The reinforcement member 14 can specifically be made of metal materials, such as high-strength phosphated steel wire, other non-hydrogen-releasing materials, etc.; or non-metallic materials, such as fiber-reinforced composite materials. The reinforcement member 14 is provided to support the internal structure of the optical cable assembly 1 to ensure the overall structural stability.

[0033] It can be understood that the composite digital cable in the present disclosure can realize data signal transmission through the optical cable assembly 1, and the signal transmission cable assembly 2 can transmit both digital signals and power signals; thus, the composite digital cable in the present disclosure can meet the needs of data signal transmission in the communication network and the power supply needs, and can simultaneously transmit data to the AP and power the POE. Furthermore, by providing a sheath layer 3 on the periphery of the optical cable assembly 1 and the signal transmission cable assembly 2, the optical cable assembly 1 and the signal transmission cable assembly 2 can be easily peeled off, which facilitates the connection between the optical cable assembly 1 and the AP and the signal transmission cable assembly 2 and the POE. In addition, by combining the optical cable assembly 1 and the signal transmission cable assembly 2, raw materials are saved and the cost of the composite digital cable is greatly reduced.

[0034] In one embodiment, the line body 12 includes an insulating layer 121 and a plurality of fiber cores 122 disposed in the insulating layer 121 .

[0035] In this embodiment, taking the number of the fiber cores 122 as six as an example, the material of the fiber core 122 is generally glass fiber, or a fiber core 122 whose main component is high-purity silicon dioxide, wherein a very small amount of dopants such as germanium dioxide and phosphorus pentoxide are also added to increase the refractive index of the fiber core 122 to light, so as to better realize the function of data signal transmission. The material used for the insulating layer 121 can be polybutylene terephthalate (PBT), polyethylene or other materials that can produce an insulating effect in actual production, and no excessive restrictions are made here.

[0036] In one embodiment, each wire pair 22 includes a twisted pair of wires formed by twisting two single wires 221 and an inner shielding layer 222 covering the outer periphery of the twisted pair of wires.

[0037] In this embodiment, each single wire 221 includes a copper conductor and an insulating sleeve sleeved on the outer periphery of the copper conductor. The insulating sleeve can be made of polyethylene or other materials that can produce an insulating effect in actual production, and no further restrictions are given here. The inner shielding layer 222 wrapped around the outer periphery of the twisted pair can well resist external electromagnetic interference, while controlling its own electromagnetic wave radiation, and will not interfere with the normal operation of other surrounding devices and networks.

[0039] In this embodiment, by arranging the filling rope 13 in the optical cable assembly 1, the structure of the optical cable assembly 1 is stabilized, more solid and durable, and can withstand greater tension and bending. When the optical cable assembly 1 is subjected to external impact or extrusion, the filling rope 13 can share part of the pressure and impact, reduce the burden on the fiber core 122, and protect the fiber core 122 from damage. Therefore, the filling rope 13 can assist in improving the tensile and sway resistance of the composite digital cable. Among them, the sum of the number of wire bodies 12 and filling ropes 13 placed on the periphery of the reinforcement 14 is at least five, and the number of filling ropes 13 can also be more than one. For example, the number of filling ropes 13 is one, and the number of wire bodies 12 is four; the number of filling ropes 13 is one, and the number of wire bodies 12 is five; or, the number of filling ropes 13 is one, and the number of wire bodies 12 is four, etc.

[0040] Reference Figure 3 and Figure 4As shown, based on the above-mentioned embodiment, the optical cable assembly 1 also includes a metal composite tape 11, which is coated on the periphery of the multiple wires and is located at the outermost layer of the optical cable assembly. Among them, the metal composite tape 11 is a metal composite tape, which can be a copper-aluminum composite tape or a copper-nickel composite tape, which has excellent conductivity and transmission efficiency, and can also protect the internal structure of the optical cable assembly 1 from interference from external electromagnetic radiation. When the optical cable assembly 1 includes a filling rope 13, the filling rope 13 is arranged in the metal composite tape 11 to make the structure of the optical cable assembly 1 stable, more solid and durable, and able to withstand greater tension and bending. When the optical cable assembly 1 is subjected to external impact or extrusion, the filling rope 13 can share part of the pressure and impact, reduce the burden on the fiber core 122, and protect the fiber core 122 from damage. The filling rope 13 and the multiple wire bodies 12 are arranged on the periphery of the reinforcement 14, and the filling rope 13 and the reinforcement 14 are both coated in the metal composite tape 11 to ensure the stability of the overall structure. It can be understood that the metal composite tape 11 can be set according to actual needs.

Among them, the hanging wire part 33 can be glued between the first sheath 31 and the second sheath 32, that is, the hanging wire part 33 is connected between the first sheath 31 and the second sheath 32 by adhesive bonding; or, preferably, the first sheath 31, the second sheath 32 and the hanging wire part 33 are integrally formed. In the production process, the sheath machine can be extruded and molded using a mold with the same appearance as the first sheath 31, the second sheath 32 and the hanging wire part 33, which reduces the operation steps and greatly improves the production efficiency. By setting the sheath layer 3, the windproof, rainproof and anti-aging properties of the composite digital cable are increased, which can not only extend the service life of the product, but also ensure the use effect and structural stability of the composite digital cable.
