Abstract
The utility model discloses a digital cable with a skeleton structure. The digital cable comprises six copper wires. In the six copper wires, each two copper wires form a twisting pair wire. A first blade, a second blade and a third blade form a zig-zag skeleton. Leaf bud sheets are arranged on the other ends of the first blade, the second blade and the third blade respectively. The first blade, the second blade and the third blade of the zig-zag skeleton and the corresponding leaf bud sheets form a first cavity, a second cavity and a third cavity. A first twisting pair wire is located in the first cavity. A second twisting pair wire is located in the second cavity and a third twisting pair wire is located in the third cavity. A polyester belt layer wraps the first twisting pair wire, the second twisting pair wire, the third twisting pair wire and the zig-zag skeleton. Gaps between polyester belt layer and the first twisting pair wire, the second twisting pair wire and the third twisting pair wire are filled with colloid elastomers which are served as an anti-water paste. By using the digital cable of the utility model, an ability of the cable to prevent tidal air and moisture from entering into the cable so that usage performance is not influenced is greatly improved.
