4 Design criteria

4.1 Design maturity criteria Under normal circumstances, electrical connectors need to carry out design work on the basis of mature electrical connectors that meet the general specifications to be certified and have The premise is stable supply for a long time, and then the process of structural analysis, limit test and other processes are supplemented to evaluate whether the electrical connector meets the requirements of aerospace applications. The application of new technologies, new processes, and new materials should undergo full and comprehensive system verification. A special verification plan should be developed for verification and Carry out the following analysis. new technologies, analysis of the adequacy of reliability design and test verification; new materials, the rationality of selection and sufficient verification Analysis of performance and correctness of use; new process, analysis of process design rationality, verification sufficiency, document completeness, and process stability. Adopt current effective standards and learn from mature technologies in the industry, including reference to structure, process, testing, test technology and local structure, Provisions for size marking, tolerance selection, material and coating selection, etc. The design should have a deeper understanding of similar products in the industry. 4.2 Autonomous and controllable criteria The components, raw materials, and processes used in electrical connectors should be provided independently in China. If there is a gap in the current domestic technology level, Develop corresponding measures. 4.3 Lightweight guidelines Electrical connectors should always pay attention to the requirements of weight limitation, and prefer lightweight design schemes on the premise of ensuring performance. 4.4 Space availability criteria Electrical connectors should consider space availability, and the specific requirements are as follows. a) The electrical connector should be suitable for the use of various space environments such as high vacuum, high and low temperature, and strong radiation; b) The electrical connector should meet the performance indicators of thermal vacuum outgassing, harmful gas, anti-radiation, antigen oxygen, anti-ultraviolet radiation, vacuum cold welding, etc. Requirements, specific performance requirements and indicators should be determined according to actual projects; ......
