Integration forming method for 1553B bus cable system

Abstract

The invention discloses an integration forming method for a 1553B bus cable system. The method includes: (1), welding and assembling coupling transform coils and isolation resistances on printed boards to form printed board assemblies; (2), on a first printed board assembly, welding first twisted-pair shielded wires at a positive end and a negative end of a first principle line, welding second twisted-pair shielded wires at a positive end and a negative end of a second principle line, and welding third twisted-pair shielded wires at a positive end and a negative end of a sub-line; and on a second printed board assembly to an Nth printed board assembly, welding second twisted-pair shielded wires at the positive end and the negative end of the second principle line, and wielding third twisted-pair shielded wires at the positive end and the negative end of the sub-line; (3), connecting N printed board assemblies from one end to the other end through the second twisted-pair shielded wires; (4), sleeving coupler casings on the N printed board assemblies and performing processes of filling and sealing; and (5), welding the third twisted-pair wires connected on all the printed board assemblies to connectors, and welding the first twisted-pair wires connected on the first printed board assembly and the second twisted-pair wires connected on the Nth printed board assembly to terminals.

Description

technical field [0001] The invention relates to a method for forming a cable network, in particular to a method for integrally forming a 1553B bus cable network. The method integrates 1553B bus couplers, terminators, connectors, and twisted-pair shielded cables in an integrated manner. Networking, so as to maintain the impedance matching of the entire network and achieve the best signal transmission performance. Background technique [0002] The 1553B bus is the abbreviation of MIL-STD-1553B, and its full name is the aircraft internal time division command / response multiplex data bus. The 1553B data bus has become the dominant system bus standard in the aerospace field due to its high noise tolerance and reliable communication. The data paths between the control systems of various new aerospace weapons and various subsystems require a large number of 1553B data buses. . [0003] The 1553B bus cable network, as the key physical path of the bus control system, is the central...
