摘　　要：主要介绍了冷氦连接器的研制与试验，以及研制中的技术难点及解决途径。此连接器的研制，解决了低温、高压下多路连接密封问题、隔热和绝热问题以及射前脱落问题。为ＣＺ－３Ａ三级冷氦增压系统得到实施提供了一个必不可少的关键设备。The development and tests of cold helium connector together with the technical difficulties in the development and their solutions are introduced. The connector has good seal and heat insulation performance under low temperature and high pressure, and can be successfully auto uncaged before launching. It provides the cold helium pressurization system of the stage 3 of CZ-3A with a key device.
