【Abstract】 In view of the needs of the optoelectronic signal rotating transmission of the airborne external platform equipment system, the traditional products have some problems such as miniaturization, insufficient lightweight and easy ignition at high voltage in high altitude environment. In this paper, an integrated forming design method of airborne photoelectric composite rotary connector is proposed. Through the integrated structural design of center shaft and insulation piece, brush holder and insulation piece, electrical contact reliability and high-efficiency coupling design of small-deflection fiber collimator, The traditional photoelectric rotary connector can not meet the small installation space of airborne equipment miniaturization and high voltage resistance and other technical problems, developed a 1 optical 5 electrical composite rotary connector product, It can meet the requirements of dynamic transmission of photoelectric signals at an altitude of 18 000 meters. At the same time, the product has passed ground and flight tests with the whole machine, and the effect is good.更多还原
