[0002] With advancements in modern network technology and intensifying competition within the automotive industry, consumers are demanding increasingly higher standards for automobiles, particularly in terms of connectivity, entertainment, and intelligence. Modern cars and high-end commercial vehicles are placing greater emphasis on in-vehicle audio-visual systems, intelligent in-vehicle network systems, and the autonomous driving systems currently under development. Consequently, automotive data cables, as the medium for information transmission within and between these systems, are also facing correspondingly higher requirements, needing to maintain stable data transmission quality within the complex environment of the vehicle. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer composite automotive data cable structure to solve the problems existing in the prior art.

[0004] The purpose of this utility model is achieved as follows: A multi-layer composite automotive data cable structure includes a pair of cable body units disposed within a sheath. Each cable body unit includes two core wires, each core wire including two conductors. Each conductor is covered within an insulation layer. A first ground wire is provided between the conductors, with the two sides of the first ground wire in contact with adjacent conductors. An aluminum foil layer is provided outside the conductors and the first ground wire. A second ground wire is provided between the core wires, with the two sides of the second ground wire in contact with adjacent core wires. A polyester tape wrapping layer is provided outside the core wires and the second ground wire. The sheath includes an inner sheath and an outer sheath, with the inner sheath filling the space between the outer side of the cable body unit and the inner side of the outer sheath.

[0005] This utility model's multi-layer composite automotive data cable structure uniquely features a three-layer protective structure: a first ground wire, an aluminum foil layer, and a second ground wire. The first and second ground wires provide robust grounding protection and current shunting capabilities, while the middle aluminum foil layer, with its excellent electromagnetic shielding performance, effectively isolates external electromagnetic interference, ensuring the purity and stability of data transmission. These three layers work together to provide unprecedented electrical protection and signal transmission quality for the automotive data cable. Furthermore, the double-layer protection design with an inner and outer sheath provides initial electrical isolation and mechanical protection, effectively resisting minor wear and initial environmental corrosion. The outer sheath further enhances the cable's durability and anti-aging properties, while also giving the cable excellent flexibility and abrasion resistance, ensuring that the automotive data cable maintains superior performance and stable data transmission under various complex operating conditions.

[0006] As a further improvement of this utility model, a pair of cable body units are arranged in close proximity, and the two core wires in each cable body unit are arranged in close proximity, and the two conductors in each core wire are arranged adjacent to each other. The structure is compact and saves space.

[0007] As a further improvement of this utility model, the conductor is a tin-plated copper conductor, which not only has excellent conductivity and low resistivity to ensure high-speed and stable data transmission, but also the tin plating layer enhances the conductor's corrosion resistance and oxidation resistance, improves the cable's durability and service life, while maintaining good flexibility and plasticity to meet the needs of the complex wiring environment inside automobiles.

[0008] As a further improvement of this utility model, the aluminum foil layer and the polyester tape wrapping layer are in a circular shape to improve the protection capability and ensure that the automotive data cable maintains excellent performance and long service life in complex and ever-changing wiring environments. The outer sheath is in a flat circular shape to reduce the overall size.

[0009] As a further improvement of this utility model, the inner sheath continuously fills the space between the outer side of the cable unit and the inner side of the outer sheath to provide sufficient protection for the internal cable unit. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the multi-layer composite automotive data cable structure of this utility model.

[0011] The components are: 1 conductor, 2 insulation layer, 3 first ground wire, 4 aluminum foil layer, 5 second ground wire, 6 polyester tape wrapping layer, 7 inner sheath, and 8 outer sheath. Detailed Implementation

[0012] like Figure 1 The multi-layer composite automotive data cable structure shown includes a pair of cable body units disposed within a sheath.

[0013] Each cable unit includes two core wires. Each core wire includes two conductors 1, each conductor 1 is covered within an insulation layer 2, and a first ground wire 3 is provided between the conductors 1. The first ground wire 3 is attached to the adjacent conductors 1 on both sides. An aluminum foil layer 4 is provided outside the conductors 1 and the first ground wire 3. A second ground wire 5 is provided between the core wires, and the second ground wire 5 is attached to the adjacent core wires on both sides. A polyester tape wrapping layer 6 is provided outside the core wires and the second ground wire 5. The sheath includes an inner sheath 7 and an outer sheath 8. The inner sheath 7 fills the space between the outer side of the cable unit and the inner side of the outer sheath 8.

[0014] Furthermore, a pair of cable units are arranged side-by-side, with the two core wires within each unit also side-by-side, and the two conductors 1 within each core wire are arranged adjacent to each other. This compact design saves space. The aluminum foil layer 4 and the polyester tape wrapping layer 6 are circular, enhancing protection and ensuring the automotive data cable maintains excellent performance and a long service life in complex and variable wiring environments. The outer sheath 8 is flat and circular, reducing the overall size. The inner sheath 7 continuously fills the space between the outer side of the cable unit and the inner side of the outer sheath 8, i.e., the portion where the polyester tape wrapping layer 6 and the outer sheath 8 do not directly contact. The inner sheath 7 effectively secures the cable unit, providing ample protection for the internal cable unit.

[0015] The multi-layer composite automotive data cable structure of this utility model has the following advantages:

[0016] (1) A unique three-layer protective structure is designed with a first ground wire 3 plus aluminum foil plus a second ground wire 5. The first ground wire 3 and the second ground wire 5 provide strong grounding protection and current shunting capability. The middle aluminum foil layer 4 effectively isolates external electromagnetic interference with its excellent electromagnetic shielding performance, ensuring the purity and stability of data transmission. The three work together to provide unprecedented electrical protection and signal transmission quality for automotive data cables.

[0017] (2) Through the double-layer protection design of inner sheath 7 and outer sheath 8, inner sheath 7 provides preliminary electrical isolation and mechanical protection, effectively resisting minor wear and preliminary corrosion from the external environment; outer sheath 8 further enhances the cable's durability and anti-aging performance, while giving the cable excellent flexibility and wear resistance, ensuring that the automotive data cable can maintain excellent performance and stable data transmission under various complex working conditions.

[0018] (3) Conductor 1 is a tin-plated copper conductor 1, which not only has excellent conductivity and low resistivity to ensure high-speed and stable data transmission, but also the tin plating layer enhances the corrosion resistance and oxidation resistance of conductor 1, improves the durability and service life of the cable, and maintains good flexibility and plasticity to meet the needs of complex wiring environment inside automobiles.

[0019] (4) The insulation layer 2 is made of high-performance insulation material, which has excellent electrical insulation performance and heat resistance. It can effectively isolate the current between conductors and prevent signal interference. At the same time, it has good flexibility and wear resistance, ensuring that the cable maintains stable data transmission performance in the complex environment inside the car and meets the high standard requirements of automotive data transmission.

[0020] (5) Polyester tape, with its high strength, wear resistance and good electrical insulation properties, is tightly and evenly wrapped around the key parts of the cable. It not only enhances the mechanical strength and tear resistance of the cable, but also provides additional electrical isolation and flame retardant protection, ensuring that the automotive data cable maintains excellent performance and long service life in complex and ever-changing wiring environments.

[0021] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
