Abstract
Description
Technical Field
[0001] The utility model relates to a cable, in particular to a composite cable. Background Art
[0002] In today's technological and industrial fields, composite cables serve as an important transmission medium, widely used in various devices and systems. However, these composite cables are not single-strand cables, but rather are composed of multiple strands of cables with different functions and materials, tightly bonded together. This design aims to achieve stable transmission of diverse signals and meet the specific cable requirements in complex environments.
[0003] However, due to their complexity and diversity, composite cables often face challenges in daily use, especially when moving or bending. Because multiple strands of cable are tightly packed, and each strand has a specific hardness and coefficient of friction, friction between the strands is inevitable when the cable is bent or moved. This frequent friction not only generates noise but, more importantly, causes surface wear and tear on the cable, potentially damaging internal structures such as insulation and conductors.
[0004] This wear and tear has a serious impact on the performance and service life of cables. Once a cable is damaged, the stability and reliability of signal transmission are greatly compromised, and in severe cases, it may even cause equipment failure or system paralysis. Especially in applications with extremely high signal transmission requirements, such as high-speed data transmission and precision control, cable damage can cause immeasurable losses.
[0005] Therefore, how to solve the problem of damage of composite cables caused by friction during movement has become an important issue that needs to be urgently addressed in the current cable design and manufacturing field. Utility Model Content
[0006] In order to overcome the shortcoming that the cables in a composite cable are damaged due to friction, the purpose of the present invention is to provide a composite cable that can isolate and protect the cables.
[0007] The technical solution is: a composite cable, including a conductor, an insulating sleeve and a sheath, the conductor is wrapped by the insulating sleeve, the sheath is wrapped around the outside of the insulating sleeve, and also includes aluminum foil and water-blocking yarn, the outside of the insulating sleeve is covered with aluminum foil, and the gap between the sheath and the insulating sleeve is filled with water-blocking yarn.
[0008] As an improvement to the above solution, both the insulating sleeve and the protective sheath are ductile.
[0009] As an improvement to the above solution, a water-blocking tape is further included, and the water-blocking tape is located on the inner surface of the sheath.
[0010] As an improvement to the above solution, the overlapping rate of the water-blocking tape is not less than 25%.
[0011] As an improvement to the above solution, weaving is also included, and the weaving is located on the inner surface of the water-blocking belt.
[0012] As an improvement to the above solution, a ring is further included, which is nested in the water-blocking yarn.
[0013] As an improvement to the above solution, a partition is further included, which is fixed to the ring and supports the sheath.
[0014] As an improvement to the above solution, partitions separate the insulating sleeves.
[0015] The space between the sheath and the insulating sleeve is filled with water-blocking yarn, which effectively improves the moisture resistance of the cable, thereby improving electrical performance and reliability. At the same time, the filler effectively reduces the friction between the conductors, thereby reducing the breakage rate of the insulating sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.
[0021] Example: A composite cable, such as Figure 1-Figure 3As shown, the eight-strand conductor 1 is divided into four groups by the insulating sleeve 2. The outer sleeve of the insulating sleeve 2 is provided with aluminum foil 3. The aluminum foil 3 is an excellent electromagnetic shielding material, which can effectively block external electromagnetic interference signals, so that each conductor 1 can work stably, and improve the stability and reliability of signal transmission. In addition, the aluminum foil 3 has good oxidation resistance and corrosion resistance, and plays an external protection effect on the insulating sleeve 2. The sheath 7 is set on the outside of the insulating sleeve 2, wherein the sheath 7 is respectively provided with a water-blocking tape 6 and a braid 4 inwardly. The water-blocking tape 6 is made of highly water-absorbent material and mainly plays a waterproof and moisture-proof function. When moisture contacts the water-blocking tape 6, the water-blocking tape 6 can quickly It absorbs and expands quickly to form an effective waterproof barrier, preventing moisture from further penetrating into the interior of the cable. This is crucial for protecting the interior of the cable from dryness and preventing moisture from damaging the internal conductor 1 of the cable, thereby increasing the service life of the cable. The braiding 4 plays the role of electromagnetic shielding, mechanical protection, and enhanced wear resistance in the cable. The gap between the sheath 7 and the insulating sleeve 2 is filled with water-blocking yarn 5. The water-blocking yarn 5 can significantly improve the waterproof performance of the cable and reduce construction and maintenance costs. A ring 8 and a partition 9 are provided in the water-blocking yarn 5. The ring 8 and the partition 9 are both made of soft plastic material. The partition 9 can separate the insulating sleeves 2.
