This invention discloses a bending fatigue enhancement structure for flat cables, relating to the field of flat cable technology. It includes a wear-resistant outer sheath, a flexible skeleton, an elastic inner liner, and a composite conductor bundle. The wear-resistant outer sheath covers the flexible skeleton, with bending stress cores at the outer ends. The flexible skeleton is internally covered by an elastic inner liner, which contains two spaced-apart composite conductor bundles. The flexible skeleton has grooves filled with an anti-oxidation coating layer, within which the bending stress cores are fixed. The interior features stress-dispersing adhesive grooves intersecting with the grooves, and high-toughness reinforcing ribs with abrasion-resistant protective sleeves are installed at the four corners. The elastic inner liner has a water-blocking tape wrapping layer on its outer side and a flame-retardant isolation layer inside. The composite conductor bundles are wrapped with cable core fixing rings and an electromagnetic shielding layer. This structure, through multiple stress dispersion, protection, and positioning designs, significantly improves the cable's bending fatigue resistance, ensuring stable transmission and safe operation, and is suitable for high-frequency bending scenarios.
