Network data transmission line

The utility model discloses a network data transmission line. Two ends and two sides of a cross beam and two ends and two sides of a vertical beam of a central cross are arc-shaped surfaces. The side surface of the cross beam and the side surface of the vertical beam form a U-shaped space, and the two side surfaces are adjacent. A twisted pair is located in the U-shaped space. Shielding layers are arranged in the cross beam and the vertical beam of the central cross in the length direction of the cross sections. The shielding layers intersect in the central region of the central cross and a channel with a round cross section is arranged in the joint. A nylon wire is arranged in the channel. Two rubber pipes are inlaid in a sheath symmetrically. A signal wire is arranged in each rubber pipe. A metal layer wraps an outer surface of a crystal head. The upper surface of the crystal head is in thread connection with a bolt. The lower surface of the bolt is in press fit with the nylon wire. The network data transmission line is advantaged by tight connection, good signal transmission performance and strong anti-deformation capability.
