[0003] The quality of the twisted pair is one of the key factors that determine the bandwidth of the LAN. The super five twisted pair also uses 4 twisted pairs and 1 tensile wire. In order to reduce signal interference, each wire in the twisted pair cable The pairs are made of two insulated copper wires twisted together, and different pairs in the same cable have different degrees of twisting. However, the structure of conventional Category 5e network wires makes it easy to cause internal and external faults when used. Interference signals are intertwined with each other and the attenuation margin is insufficient, and because the super five types of unshielded network data cables are laid out in the form of coils during use, the tensile strength and resistance to core deformation are of great value to them. has an important influence

Abstract
The invention relates to a super-five-type non-shielding network data line comprising a PVC sheath and four groups of twisted-pair units arranged inside the PVC sheath. Each group of twisted-pair units is formed by twisting of two wire cores; and the wire cores include conductors and insulating layers arranged outside the conductors. A ripping cord is arranged between the four groups of twisted-pair units and the PVC sheath. Three first protrusions and a first second protrusion are arranged at the inner wall of the PVC sheath; the first protrusions consist of first protruding heads and second protruding heads; and PE frames are arranged inside the first protrusions and include horizontal racks, first convex ribs, and second convex ribs. The data line has characteristics of ingenious structural design, compact structure, high practicability, fast transmission efficiency, good insulating performance, high tensile strength, and good anti-wire-core deformation performance.
Description
technical field [0001] The invention relates to a category five super unshielded network data line, which belongs to the technical field of communication networks. Background technique [0002] Unshielded twisted-pair cables are composed of multiple pairs of twisted-pair wires and a plastic sheath. The International Electrical Industry Association defines five different quality levels for twisted-pair cables. The third and fifth types are often used in computer networks. As well as Category 5e and the current Category 6 unshielded twisted-pair cables, among them, Category 5 and Category 6 twisted-pair cables use increased winding density and high-quality materials to greatly improve the properties of the transmission medium. Various parameters have been greatly improved, and the bandwidth has also been extended to 250MHz or higher. [0003] The quality of the twisted pair is one of the key factors that determine the bandwidth of the LAN. The super five twisted pair also use...
