DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The novel flat cable for towing involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work fall within the scope of protection of the present invention.

[0020] Reference Figures 1 to 4 The utility model provides a new type of flat cable for towing, including a sheath layer 1, and also includes: a shielding layer 2, a soft copper core conductor 3, a galvanized steel wire rope 4 and an insulating protective layer 5. The shielding layer 2 is fixedly connected to the inside of the sheath layer 1, the soft copper core conductor 3 is fixedly connected to the inside of the shielding layer 2, the galvanized steel wire rope 4 is fixedly connected to the inside of the shielding layer 2, the insulating protective layer 5 is fixedly connected to the inside of the shielding layer 2, the soft copper core conductor 3 is inserted and connected with the wire core 301, and the side of the soft copper core conductor 3 is fixedly connected with the insulating protective layer 5. The sheath layer 1 is the outermost layer of the cable and is made of high-strength material. It provides a solid external protection for the cable, effectively resists physical impact, chemical corrosion and mechanical wear in the external environment, and ensures the durability of the cable in complex industrial environments. The shielding layer 2 forms an electromagnetic shielding layer 2 through its conductive properties. , isolating the signal transmission inside the cable from external electromagnetic interference, ensuring the stability and accuracy of signal transmission. At the same time, the shielding layer 2 not only fixes the soft copper core conductor 3 as the signal transmission body, but also cleverly integrates the galvanized steel wire rope 4. This design not only enhances the tensile strength of the cable, but also improves the mechanical stability of the cable, enabling it to maintain structural integrity during suspension or movement. The wire core 301 inserted inside the soft copper core conductor 3 is the core component of signal transmission. Through its efficient conductive performance, it realizes the fast and stable transmission of electrical signals, and the insulating protective layer 5 surrounding the soft copper core conductor 3 plays a vital insulating role. It effectively isolates the electrical connection between the wire cores 301, prevents current leakage and short circuit, and further improves the safety of the cable.

[0021] The side of the sheath layer 1 is fixedly connected to the aramid tensile filling layer 201 , the side of the aramid tensile filling layer 201 is fixedly connected to the torsion-resistant braided layer 202 , and the side of the torsion-resistant braided layer 202 is fixedly connected to the soft copper core conductor 3 .

[0022] Among them, the sheath layer 1 adopts a strong TPU sheath. The TPU material provides a solid external protective layer for the cable with its excellent wear resistance, oil resistance and high strength. When the cable is suspended, moved or subjected to physical impact, chemical corrosion and mechanical wear in the external environment, the TPU sheath can effectively resist these adverse factors, ensuring the integrity of the cable's internal structure and the stability of signal transmission. At the same time, the elasticity of the TPU material also gives the cable a certain flexibility and bending resistance, enabling it to adapt to various complex industrial environments.

[0023] Among them, an aramid tensile filling layer 201 is filled between the sheath layer 1 and the shielding layer 2. The material of the aramid tensile filling layer 201 uses aramid reinforced filling. The aramid tensile filling layer 201 not only increases the longitudinal tensile strength of the cable, making the cable less likely to break when subjected to tension, but also through its unique fiber structure, it can effectively disperse the stress concentration of the cable during the force process.

[0024] Among them, the shielding layer 2 adopts a nitrile rubber inner sheath, which also has a certain tensile strength and can enhance the overall tensile performance of the cable. When the cable is subjected to tension, the nitrile rubber inner sheath can share part of the tension and protect the conductor and insulation layer inside the cable from damage.

[0025] Among them, the side of the insulating protective layer 5 is fixedly connected with a nitrile rubber insulating layer 501. The insulating protective layer 5 serves as the first insulating barrier for the internal core 301 of the cable, preventing current leakage or short circuit between different cores 301. The nitrile rubber insulating layer 501 serves as an additional insulating layer, further enhancing the insulation effect and providing double insulation protection for the cable.

[0026] Working principle of the utility model: The core structure of the cable is composed of multiple layers of carefully designed materials, each layer has a specific function, and they work together to achieve the high performance of the cable. First, from the outside to the inside, the outermost layer is the sheath layer 1, which is made of high-strength TPU material. TPU provides the first solid protective barrier for the cable with its excellent wear resistance, oil resistance and high strength. This sheath can not only effectively resist physical impact, chemical corrosion and mechanical wear in the external environment, but also reduce direct contact with clamps or other objects during cable hanging or moving, thereby extending the service life of the cable. Closely attached to the inside of the sheath layer 1 is the aramid tensile filling layer 201, which is reinforced and filled with aramid fibers. Aramid is known for its extremely high tensile strength and modulus. It is a high-performance material commonly used in aerospace, military and other fields. In cables, the aramid tensile filling layer 201 not only enhances the overall tensile strength of the cable, but also effectively disperses the stress concentration of the cable when it is subjected to external forces through its good filling properties, thereby improving the fatigue resistance of the cable. In addition, aramid material also has certain flame retardancy, which further enhances the safety of the cable. Next is the torsion-resistant braided layer 202, which is tightly wrapped around the inner side of the aramid tensile filling layer 201. The torsion-resistant braided layer 202 is woven with high-strength and high-toughness materials. Its unique braiding structure gives the cable excellent torsion resistance. During the cable suspension or movement, even if complex mechanical changes are encountered, the torsion-resistant braided layer 202 can also effectively resist the twisting and deformation of the cable, maintain the stability of the internal structure of the cable, thereby ensuring the continuity and accuracy of signal transmission. The shielding layer 2 of this cable adopts a nitrile rubber inner sheath. Nitrile rubber has good oil resistance, wear resistance and aging resistance, and is very suitable for use in industrial environments. The main function of the shielding layer 2 is to isolate the internal signal of the cable from the mutual interference of the external electromagnetic environment. It is tightly wrapped around the outside of the soft copper core conductor 3 and the galvanized steel wire rope 4 to form an effective electromagnetic shielding barrier. The soft copper core conductor 3 is the signal transmission body of the cable. It is composed of multiple fine wire cores 301. These wire cores 301 are arranged in a specific twisting method to improve the flexibility of the cable and the signal transmission efficiency. The side of the soft copper core conductor 3 fits tightly. The insulating protective layer 5 not only serves to isolate the electrical connection between the wire cores 301, but also prevents current leakage and short circuit through its good insulation performance. In addition, a layer of nitrile rubber insulation layer 501 is fixedly connected to the side of the insulating protective layer 5. This additional insulation layer further enhances the insulation performance of the cable and improves the safety and reliability of the cable. The galvanized steel wire rope 4 is also cleverly integrated into the cable. The galvanized steel wire rope 4 provides additional mechanical support and tensile strength for the cable with its high strength and corrosion resistance. When the cable is subjected to large tension or bending, the galvanized steel wire rope 4 can effectively share the stress and protect the soft copper core conductor 3 from damage. At the same time, the galvanized steel wire rope 4 also has a certain torsional resistance.It works together with the torsion-resistant braided layer 202 to improve the torsion resistance of the cable.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
