Description

Technical Field

[0001] The present invention belongs to the technical field of data cables, and in particular relates to a fracture-resistant vehicle-mounted data cable and a method for manufacturing a fracture-resistant outer sheath material thereof. Background Art

[0002] In modern life, mobile devices have become an integral part of our daily lives. Data cables, as essential tools for connecting devices to power sources, are therefore particularly important for their performance and durability. Traditional data cables are prone to breakage during use, especially in confined spaces like cars, where they are more susceptible to frequent bending and impact. Data cable breakage not only impacts the user experience but also wastes resources and pollutes the environment. Existing data cables are often made of materials such as PVC or silicone, but these materials age and become brittle over time, especially after repeated bending, which can easily lead to cracks. This significantly shortens the cable's lifespan and increases the frequency of replacement. Summary of the Invention
