Connector products began in 1939 during the Second World War. After the war, with the development of consumer electronic products such as TVs and telephones, connectors were rapidly expanded from early military uses to general consumer electronics, automobiles, and computers. field.

The development of China's connector industry is also closely related to military use. From the budding stage in the 1940s, the United States invested in the production of military connectors in China to equip the Chinese army in war. In 1949, the US capital retreated, and some technical equipment remained, forming the prototype of the development of China's connector industry in the future.

From 1950 to 1970, as the initial stage of development, China formed pre-war private enterprises and related enterprises into public-private joint ventures, and established various subordinate factories, local state-owned factories, and collective factories, such as the 796 Factory, the 851 Factory, and the 850 Factory. Factory, 117 Factory, Zhenjiang Connector Factory, Beijing Radio Component No. 9 Factory, Shanghai Radio No. 9 Factory, etc. The main applications of the connectors produced at this time are related to the military industry and the aerospace industry.

In the 1980s, China implemented the policy of reform and opening up, and began to switch to the production of connectors for consumer electronic products for people's livelihood. At this time, due to China's continuous economic reform and opening to the outside world, many foreign businessmen entered the mainland market to invest. In 1987, Japan's Daiichi Electronics, Shenzhen SEG Electronics Group and Shanghai Radio No. 9 Factory jointly invested and established (Shenzhen Sandu SAS Electronics Co., Ltd.) as the earliest foreign joint venture. After the 1990s, encouraged by various foreign investment policies and incentive measures of the mainland authorities, almost all connector manufacturers around the world transferred their production bases to China, including the largest world-class connector manufacturers, such as: AMP, MOLEX, Amphenol, etc. all successively invested and set up factories in China in 1992. At the same time, many other foreign companies in the 1980s, with the rise of the personal computer industry, connector manufacturers have sprung up, including JST, KET, JAM, FCI and other manufacturers, in addition, Taiwan Kangxu, Taiwan Amp, Taiwan Airlines International manufacturers such as electronics have also come to the mainland to invest.

For example, Taiwan's connector industry also entered the initial stage in the 1970s. Major manufacturers such as Xinsheng Seiko, Liangwei, Ruifang Electronics, Xinyin, Zhijia, etc., mostly produce low-end products such as power sockets, plugs or wiring harnesses. Mainly, the scale of the company is generally small. Even DuPont of the United States has come to China to set up a factory to produce connectors. They bring advanced machinery and equipment and a relatively large-scale production system, which can be said to be the pioneer in opening the connector industry.

Around 1993, with the upsurge of computer factories investing in this land in China and the consideration of cost reduction, foreign connector manufacturers went to China to invest and set up factories, which made the connector industry develop rapidly! That is, by 2000, not only Taiwan , Hong Kong, Japan and Europe and other connector factories have also strengthened their investment in China, which has increased the output value of China's connectors, and the production scale of China's connector industry has also provided customer needs in various industries around the world.

In recent years, the huge domestic information industry market has provided considerable space for the connector supporting market. In addition to the supporting shares related to other industries, the annual growth rate is 15%. The development speed of the connector supporting market for communications and computers to 75% to 35%. Exports increased by 23.9% year-on-year, while imports increased by 60.4% year-on-year. Among them, connector exports reached 310 million US dollars and imports reached 543 million US dollars. The presented shortfall amounts to $233 million. In 2000, the domestic connector demand reached 9 billion to 10 billion yuan. Communications, computers and peripherals account for more than 50%; consumer products account for about 30%.
