| Abstract: | Taking the new high-density row plug-in cable assembly used for the first time on the Internet satellite as the research object, the manufacturing technical requirements and working principle of the integrated row plug-in electrical connector are introduced, and the factors affecting the installation of this type of cable are studied from the structural analysis of the electrical connector. For the first time, the installation method of the new high-density row plug-in cable is proposed, and the bending radius requirements, lashing requirements, tightening moment value requirements and disassembly methods using special tooling of this type of cable are proposed. After the actual on-orbit performance test of the subsystem is verified, the installation technology can significantly reduce the performance degradation of the new high-density row-plug cable assembly in the high-throughput and high-saturation signal transmission state, successfully solve the installation and disassembly problem of the cable in the narrow space of the satellite, improve the installation accuracy of the cable of this type in the narrow space of the satellite and the on-orbit reliability of the subsystem, and provide technical guidance and process basis for the subsequent application of the new high-density row-plug cable assembly in the subsequent satellite batch application. |
