Abstract
The utility model discloses a category 6+ skeleton type cable comprising eight copper conductors and a cross-shaped skeleton composed of a transverse blade and a vertical blade, wherein the copper conductors are intertwisted in pairs to form four twisted pairs. The two ends of the transverse blade are provided with leaf bud pieces. The fist twisted pair, the second twisted pair, the third twisted pair and the fourth twisted pair are respectively arranged inside a first cavity, a second cavity, a third cavity and a fourth cavity correspondingly. The fist twisted pair, the second twisted pair, the third twisted pair, the fourth twisted pair and the cross-shaped skeleton are wrapped by polyester belt layers. Inside the first, second, third and fourth cavities, colloidal elastomers functioning as a water blocking ointment are filled among the polyester belt layers, the fist twisted pair, the second twisted pair, the third twisted pair and the fourth twisted pair. According to the technical scheme of the utility model, due to the adoption of the skeleton type structure, the tidal air and the water are largely prevented from entering the cable to influence the usage performance of the cable.
