Multi-terminal data transmission line

The utility model discloses a multi-terminal data transmission line. Redundant configuration is adopted for the transmission line, wherein at least two lines multiplex one signal, the transmission line is internally provided with 1-n rows of signal lines, one end of each of the 1-n rows of signal lines is inserted into the main plug-in and is electrically connected with the expansion mainboard through the main plug-in, and the other end of each of the 1-n rows of signal lines is electrically connected with 1-n auxiliary plug-ins in sequence. The utility model relates to a multi-terminal data transmission line. An n-core connector is connected with a terminal drive. Finally, data transmission is distributed to each terminal signal. Each piece of data is controlled in real time; and meanwhile, through redundancy configuration, when one wire is in poor contact due to external influence, the other one or more wires can completely perform data transmission, so that the cable has the characteristics of long-term re
