Embodiment Construction

[0012] 2 nanosecond data line, the process is: draw and anneal the Φ2.6mm copper rod, extrude it and insulate it with high-density polyethylene to generate a single insulated copper wire; twist the insulated single wire in pairs At the same time without adhesion, multiple twisted wires are cabled to form a cable core wire, and the cable core wire is extruded and extruded on the periphery to form a sheath. The sheath includes a PVC low-smoke and halogen-free outer layer and its inner layer Polyester strap.

[0013] Such as figure 1 As shown, the 2 nanosecond data line includes an outer sheath and an inner cable core wire. The sheath includes a PVC low-smoke halogen-free outer layer 1 and a polyester tape 2 inside it. The cable core wire includes A plurality of twisted wires 3, the inner core of each twisted wire 3 is a copper wire single wire 4, and the surface layer of the copper wire single wire 4 is a high-density polyethylene coating 5.

Abstract

The invention relates to a 2 nanosecond data line. The process comprises the following steps of: drawing and annealing a Phi 2.6mm copper bar; coating membrane high-density polyethylene during extrusion for insulation and generating a single insulating copper wire line; carrying out pair twisting on the insulating single line without conglutination; leading a plurality of pair twisting lines to form a cable core line by a formed cable; extruding the cable core line and forming a sheath at the periphery by extruding. The sheath comprises a PVC low-smoke halogen-free outer layer and an inside polyester band. The 2 nanosecond data line produced by the process realizes long data transmission distance, high video quality, regular pixel arrangement, clear edge and picture and less vertical black spot and double image in the process of video transmission. The invention also discloses a structure of the 2 nanosecond data line.

Description

technical field [0001] The invention relates to a process and structure of a 2 nanosecond data line. Background technique [0002] Today's high-resolution video displays require high-performance cables with low signal delay and low return loss. Usually, these systems use bundled coaxial cables when the cables are interconnected, and the bundled coaxial cables are relatively high in terms of production process and cost. In view of the economy of unshielded twisted pair (UTP) relative to coaxial cable, our company specially designed and adopted UTP transmission equipment for the transmission of RGB component video signals. At the same time, the same UTP can also be used in the user's LAN wiring so that there is no need to use two independent cables. To meet this new requirement for video, data UTP cables. Our company has developed 2nsUTP (2 nanosecond unshielded twisted pair). Contents of the invention [0003] The purpose of the present invention is to provide a 2 nanos...
