Huafeng company is China's largest power connector scientific research production base, is many domestic and foreign standards organization member unit, its core products are widely used in military, telecommunications, industry, automobile, etc, and are sold far to Germany, Britain, France, the United States, Finland, Russia and other developed countries and regions. In "the no. 7 shenzhou spaceship" huge system, huafeng connector products supporting the astronaut, manned spacecraft, carrier rocket launch, measurement and control system, etc. In the "god" of flying in seven plan, astronauts 岀 space walks, is believed to be in China's manned space "significant breakthrough", in the world at present only Russia and the United States do this. Because of this, ensure survival, work and communication astronauts outside the cabin of the suits the focus of attention of the world. Be proud of is, the astronauts 岀 space walks will put on domestic outside the cabin space suits, this is called the "flying" outside the cabin of the suits and has 90 DuoGe key parts, each parts are developing difficulty.

   According to information, outside the cabin connector and cable the inflexibility of the suits did the exclusive development by huafeng, fill a blank in China. It is because of these key connectors, astronauts can call "heaven and earth", all the instructions can be in the middle of implementation. It is no exaggeration to say, huafeng connector up is a lifeline. Astronauts 岀 space walks, 0.1 billion when the audience can see a long "electricity umbilical cord," astronauts information transfer by all this "electricity umbilical cord" finished the umbilical cord "both ends of the used, is huafeng connector. "That's not funny things, to do 100% reliability." Huafeng company a senior engineer said.

   On the TV screen, audience can even see huafeng connector. Astronauts 岀 space walks, right there is a "blue waist button", the rubik's cube is actually huafeng connectors, its function is mainly the voice communication and physiological signal transmission.

   In huafeng for manned space engineering supporting, the most difficult task is to develop the full set of the suits, including internal harness suits suits connector cable, external connector cable, helmets, beams, communication cable wiring harness and three series which ten DuoZhong connector. Suit wire connectors and high technical content, high precision machining, huafeng took a lot of effort to conquer, the composite material development and production of a series of technical difficulties.
