[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-4 This durable USB cable includes a terminal 1, a braided tail structure 2, and a data cable 3. The braided tail structure 2 has an inverted cone shape and is located at the bottom of the terminal 1. The data cable 3 passes through the braided tail structure 2 and is electrically connected to the terminal 1. The data cable 3 includes multiple braided wires 4, which are twisted and braided into shape. The braided tail structure is integrally injection molded, improving production efficiency. The head and tail of the braided tail structure are integrally injection molded, and the long braided tail provides a longer protection range for the cable exit point, with a gentler bending angle, preventing the cable sheath from tearing due to bending. The improved braided tail structure also enhances the overall resistance to bending and breakage. Since most damage points are located at the head and tail of the terminal, conventional structures use separate injection molding, and the wire is easily affected by stress concentration when bending at the braided tail, leading to damage. This patent uses integral injection molding of the head and tail of the terminal, thickening and encapsulating a large area of ​​the head and tail of the terminal. The long braided tail provides a longer protection range for the cable exit point, with a gentler bending angle, preventing the cable sheath from tearing due to bending. The wire exit point of the net adopts an inverted cone shape instead of the traditional direct wrapping. This increases the contact area between the wire and the net tail when bending, which can distribute the stress more evenly on the net tail when bending, reducing the chance of cracking caused by stress concentration on the outer sheath.

[0017] like Figure 1-4 The braided wire 4 includes three sets of twisted pairs 5, which are installed side by side; the combination of the three sets of twisted pairs makes the wire stronger and improves its service life.

[0018] like Figure 1-4 The twisted pair assembly 5 includes two conductors 10, which are twisted together; the twisted pair installation is more compact and less prone to breakage.

[0019] like Figure 1-4The conductor 10 comprises multiple conductors 6 and an insulation layer 7, which wraps around the outside of the conductors 6. The insulation is made of polyetheretherketone (PEEK), which improves flexibility and fatigue resistance. The PEEK material has the following mechanical strength data: tensile strength 97 MPa, elongation 150%, melting point 334℃, long-term operating temperature 250℃, and short-term operating temperature 300℃. Compared to traditional polyvinyl chloride (PVC) materials, PEEK material, in addition to the above superior properties, also has advantages such as being halogen-free, non-toxic, environmentally friendly, soft, elastic, fatigue-resistant, weather-resistant, acid and alkali resistant (soluble only in concentrated sulfuric acid at room temperature), resistant to humid environments, resistant to various organic solvents, and wear-resistant. The conductors consist of six types of conductors plus bulletproof wires. The sufficiently fine monofilaments increase the flexibility of the wire, while the bulletproof wires strengthen its tensile strength.

[0020] like Figure 1-4 The conductor 10 includes a shielding layer 8 and an outer sheath 9, with the shielding layer 8 located between the insulation layer 7 and the outer sheath 9. The shielding monofilament structure is an extremely fine copper wire + fiber filament structure, further enhanced by a twisting process to greatly improve its resistance to bending and breakage. The outer sheath is made of silicone material to improve its softness and ductility. The tail structure is changed to integral injection molding to improve production efficiency. Conventional braiding methods have poor bending resistance, and most breaks occur first in the shielding layer. After the braided copper wire breaks, it moves with frequent bending, and the broken copper wire pierces the insulation and outer sheath layers. Since the outer sheath is usually thin, it will crack at the piercing point. This patent improves the braiding structure by changing the original 0.1mm diameter copper wire to an extremely fine copper wire, mixed with fiber filaments. Before braiding, a twisting process is used to twist the fine copper wires together into a small strand, and then the multiple strands are tightly arranged and braided, greatly improving the bending resistance. Even if the copper wire breaks, its very small diameter greatly reduces its hardness, preventing it from piercing the insulation and outer sheath. Meanwhile, due to the extremely small diameter of the single filament, the bending resistance is greatly improved. The addition of mixed fiber filaments further enhances this resistance. Outer sheath damage is the most common cause of data cable failure, typically occurring at the terminal ends due to deformation caused by prolonged bending. Many manufacturers use inferior PVC materials to reduce costs, significantly reducing bending fatigue resistance. Our solution uses a more flexible and highly extensible silicone material, eliminating concerns about sheath damage at corners even with frequent bending, and providing a better feel.
