Development history of Chinese military circular connector (aviation plug)

It can be said that China's military circular connectors are basically developed in the environment of "demand driven development", focusing on imitating other countries' products and standards. Until the establishment of the "211" electrical contact laboratory, China began to study the "connector" as an independent discipline. The development history of China's military connectors is basically divided into three stages: from the beginning of the founding of the people's Republic of China to the 1960s and from the 1960s to the 1990s, Since the 1990s.

The first stage: from the early days of the founding of the people's Republic of China to the 1960s.

The earliest electrical connector factory in China was Shenyang 117 factory (now Shenyang Xinghua Aviation Electrical Appliance Co., Ltd.) established in 1957. It mainly imitated the electrical connectors for aircraft in service at that time. These mil d38999 connectors were equivalent to the military standard products of the Soviet Union in the 1930s and 1940s. Later, with the development of air and ground weapons and equipment, professional connector production factories for various systems were established one after another. By the end of 1960s, the main batch series were p series, PR series, PD series, Y2 series and Y4 series. The main characteristics of connectors in this period are heavy mass, large volume and slow insertion and separation speed. At present, these products are only used for early Soviet style equipment in military industry.
