Description

Technical Field

[0001] The utility model belongs to the technical field of communication cables, and particularly relates to an integrated structure of a communication cable. Background Technique

[0002] The metal-rubber communication cable is a communication cable that combines the characteristics of metal and rubber. Its internal conductive wire core usually uses metal materials such as copper or aluminum to conduct current. The outer layer is covered with a rubber sheath, which has good wear resistance, flexibility, anti-aging property, waterproof and moisture-proof property, etc., and can protect the cable from damage by the external environment and improve the service life of the cable.

[0003] In addition, the metal-rubber communication cable also has excellent electrical properties such as high conductivity, low resistance, excellent insulation performance, etc., to ensure the stability and reliability of signal transmission. At the same time, its flexibility makes the cable more convenient to install and wire, and can adapt to various complex construction environments.

[0004] The metal-rubber communication cable has become an indispensable part of the communication field with its excellent performance and wide application fields. With the continuous development and progress of communication technology, the metal-rubber communication cable will continue to play an important role and provide people with more efficient, stable and safe communication services.

[0005] However, the existing communication cables will be subjected to repeated torsional forces during use. When the cable is repeatedly twisted, its internal structure is damaged or deformed, and this damage will seriously affect the electrical performance of the cable, resulting in signal transmission interruption or instability, leading to a decline in cable performance, signal transmission interruption or even cable failure. Content of the Utility Model

[0006] The purpose of the utility model is to provide an integrated structure of a communication cable to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] It includes a cable core body and a protective sleeve. The cable core body includes a load-bearing member, a number of adjusting members, a cable and an optical cable. The cable, the optical cable and a number of adjusting members are axially and orderly stranded around the load-bearing member, and there is a fusion connection between the cable core body and the protective sleeve; both the protective sleeve and the adjusting members are thermoplastic elastomers.

[0009] Further, the density of the cable is ≤1.025 g / cm 3 .

[0010] Further, the thermoplastic elastomer is TPE.

[0011] Further, the TPE is a limited foaming material, the conductor is an oxygen-free copper wire, and the material of the load-bearing member is Kevlar.

[0012] Further, the load-bearing member is arranged at the center of the cable.

[0013] Further, the cable includes a plurality of strands of copper wires and an insulating layer wrapping the copper wires.

[0014] Further, the insulating layer is a TPE limited foaming material or a Teflon limited foaming material.

[0015] Further, the optical cable includes a plurality of strands of optical fibers and an insulating layer wrapping the optical fibers.

[0016] Further, the insulating layer is a TPE limited foaming material or a Teflon limited foaming material.

[0017] Further, the cable and the optical cable are axially and orderly stranded around the load-bearing member.

[0018] Further, the density of the TPE limited foaming material is 0.9 - 1.0 g / cm 3 .

[0019] The utility model is designed with a cable, an optical cable and a load-bearing member, and the cable and the cable are axially and orderly stranded around the load-bearing member, ensuring that the cable and the optical cable have strong stiffness under the action of the load-bearing member.

[0020] The utility model is designed with a cable, an optical cable and a load-bearing member to form a cable core. The cable core and the protective sleeve are melt-connected, so that the contact surface between the cable core and the protective sleeve becomes a melt-integrated structure. In addition, under external factors such as wind, sea waves, tides, ocean currents, etc., irregular water masses and turbulences are formed. The water masses or turbulences cannot be completely released by the swivel, resulting in repeated torsion of the cable. This structure ensures that when the cable is repeatedly twisted, its internal structure is not easily damaged or deformed, ensuring the electrical performance and signal transmission stability of the cable, and increasing the service life of the cable.,

[0021] The cable density of the utility model is ≤1.025 g / cm 3 , ensuring that the cable maintains zero buoyancy or a floating state in seawater.

[0022] Both the insulating layer and the protective sleeve of the utility model are limited foaming materials, which can ensure that the foaming rate of the foaming material is determined according to the density of the copper wire and the optical fiber during the preparation of the cable, realizing that the cable density is ≤1.025 g / cm 3 , ensuring that the cable maintains zero buoyancy or a floating state in seawater.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: The cable prepared by the present utility model is an integral structure. During use, under the action of repeated torsional forces, the stability and integrity of the internal structure can be ensured, guaranteeing the electrical performance of the cable and the transmission of signals; the density is smaller than that of seawater, and the cable can remain floating in seawater.
