Research of Process Optimization and Analysis on the Retaining Ring Shedding Problem of the J30JHT Connector of a Satellite Constellation

The J30JHT connector is very concerned in AIT process of a batch of satellite constellation as the auxiliary retaining ring is prone to fall off in the process of precision plug assembly. In order to ensure the quality of the J30JHT connector plugging process and promote the stability of satellite assembly, it is necessary to propose an effective method to prevent the retaining ring fall off. In this paper, the characteristics of the assembly structure of the electrical connector are briefly introduced, and the fault tree analysis and technical positioning are carried out. The detailed analysis of the power transmission characteristics of the key plug in and out process is carried out. After summarizing the practical experience of mature assembly engineering, a best precision assembly process which can prevent the retaining ring fall off is presented during the plug in and out of the J30JHT connector. Finally, through a batch of satellite constellation assembly, the proposed process optimization method is proved to be sophisticated and logical, and the process parameters are stable and complete, which can ensure the quality and safety of the J30JHT connector precision plug assembly.
