When the Republic of the spaceship from the depths of the desert again and again, in addition to holding my breath like everyone else, sharing the rocket from the ground to the separation of the arrow ship unforgettable moments, for each successful spaceship test cheering, as an old aerospace science and technology workers, I have more than ordinary people a special feeling and responsibility. Because I have participated in the acceptance, failure analysis and reliability screening of various connectors on the spacecraft, I know the role and status of connectors in aerospace system engineering, as long as there is a small mistake in thousands of contacts, it will lead to the failure of the entire test. Failure and success, ineffectiveness and reliability, are two contradictory sides. Only by carefully summarizing the lessons learned, can failure be transformed into reliability, and a record of success can be maintained.
Aerospace electrical connectors face new opportunities
The quality and reliability of aerospace electrical connectors are directly related to the success or failure of aerospace system engineering. In the process of developing aerospace electrical connectors with Chinese characteristics, products such as micro-rectangular electrical connectors developed by Guizhou Aerospace Electrical Appliance Co., LTD., separation and fall off electrical connectors developed by 825 factory, and push-pull environmental resistance and rapid separation electrical connectors developed by 693 factory enjoy high popularity in China. It has been successfully applied to key parts of space system engineering with high contact reliability requirements, and has made extraordinary contributions to key system projects such as Shenzhou spacecraft and Chang 'e lunar exploration. We can say without exaggeration: there is no highly reliable aerospace electrical connector with Chinese characteristics, there will be no success of these aerospace systems engineering.
Looking back on the development of China's aerospace electrical connector over the past 50 years, it has experienced three stages of imitation Soviet in the early days of the founding of the country, the transfer from imitation Soviet to imitation American in the early days of reform and opening up, and the transition from imitation American to independent development after entering this century. After nearly 30 years of reform and opening up, China's comprehensive national strength has increased significantly, and the aerospace electrical connector industry has a number of famous enterprises with certain research and development capabilities, independent intellectual property rights and national brands. Reform and opening up to today, China has developed many aerospace electrical connectors with Chinese characteristics. The era of over-reliance on imports and complete copying of foreign electrical connectors is gone forever.
In order to achieve the goal of building a moderately prosperous society in all respects by 2020 proposed by the 17th National Congress of the Communist Party of China, many national key system projects will be launched one after another, such as space technology such as lunar exploration, which needs to be developed and produced with independent intellectual property rights. High vacuum separation electrical connectors, high vacuum sealed electrical connectors, space suit electrical connectors, solar panel electrical connectors and high-density, highly reliable, miniaturized high-speed data electrical connectors that can be used for satellite, spacecraft, space station work have ushered in new opportunities for the development of Chinese characteristics of aerospace electrical connectors.
Strict management to ensure high quality
However, we must also soberly see that there are still many difficulties and problems in the process of developing Chinese characteristics aerospace electrical connectors, and we are also facing huge challenges while welcoming development opportunities.
The role and position of aerospace electrical connectors in the whole machine should be fully understood and paid enough attention to. At present, some views believe that the aerospace electrical connector is low in the technical content of various components, limited to plugging and unplugging, not as complex as integrated circuits, so relax the technical training of design, process, inspection and other personnel and the technical basic work of production process equipment and testing instruments. To this end, the production and use of aerospace electrical connectors must change the concept, timely study, learn from, introduce and digest and absorb the production of new materials, new processes, new technologies, new equipment, and constantly improve their own design, technology and other specialized levels in order to create a new type of aerospace electrical connectors.
