Description

Novel network cable switching device

Technical Field

The utility model relates to the technical field of computer lines, in particular to a novel network line switching device.

Background

The network cable is a connecting cable commonly used in computer interconnection, and the network cable commonly used is as follows: twisted pair, coaxial cable, optical fiber, etc. Most local area networks are networked using unshielded twisted pair (UTP-unshielded twisted pair) as the transmission medium for wiring. The UTP network cable consists of twisted pair wires with a certain length and RJ45 crystal heads. Twisted pairs are twisted together in 4 pairs separated by 8 different colored wires. The international fabrication of twisted pair wires is in accordance with standards set by the american Electronics Industry Association (EIA) and Telecommunications Industry Association (TIA), EIA/TIA568A and EIA/TIA568B, respectively. Line sequence of EIA/TIA568A standard: green-1, green-2, orange-3, blue-4, blue-5, orange-6, brown-7, brown-8; line sequence of EIA/TIA568B standard: orange white-1, orange-2, green white-3, blue-4, blue white-5, green-6, brown white-7, brown white-8. When two crystal heads of one net wire adopt the same line sequence, the net wire is called a straight-through net wire, for example, the crystal heads at two ends of the net wire adopt EIA/TIA568A line sequences to form EIA/TIA568A line sequence straight-through net wires, and the crystal heads at two ends of the net wire adopt EIA/TIA568B line sequences to form EIA/TIA568B line sequence straight-through net wires; otherwise, the crossed network lines are adopted by different line sequences. The pass-through network is used to connect between a host and a switch/hub, or between a router and a switch/hub. Cross-network wires are used to connect switches to switches, hosts to hosts, hubs to hubs.

Typically, people connect computers to the internet using a direct network cable, but when two computers, two hubs, or two switches between peer ports need to be connected, a cross network cable is required. Because of unusual usage, users usually do not prepare cross wires, temporary customization is needed when the cross wires are really needed, and a special network technician is needed for the manufacturing method, and if the direct network wires are mistakenly used or directly used as the cross wires, network data transmission faults can be caused, and a computer cannot work normally.
