Application field of RF coaxial connector

In the application field of RF coaxial connectors, consumer electronic products generally do not have so high requirements for reliability, because even if the product fails and may be restarted, it will be normal, but once the product fails in military products, medical products, automotive products, aviation products and important industrial equipment, the consequences will be serious, Therefore, coaxial connectors with higher reliability must be used in this situation. BNC is the earliest RF coaxial connector. During World War II, due to the urgent need of war and the damage of various shipborne airborne electronic equipment, a large number of U.S. sea and air combat weapons were damaged to be repaired. In order to reduce the repair time, the U.S. Department of the Navy concentrated some excellent scientific researchers and engineers, In a relatively short period of time, the invention of fast plug-in and separation connector BNC (bayonets - Navy connector) has become the originator of RF coaxial connectors all over the world. With the development of radar, radio and microwave communication, N, C, TNC and other series have emerged. After 1958, small products such as SMA, SMB and SMC have appeared. In 1964, the U.S. military standard Mil-C-39012 general specification for RF coaxial connectors was formulated. Since then, RFC began to develop in the direction of standardization, serialization and generalization. Therefore, the earliest development began from the military engineering department. Therefore, the United States is the largest manufacturer and consumer of general-purpose RF connectors in the world. Of course, its technical level is also first-class; Therefore, the U.S. military standard mlc39012 is considered to be the highest standard of RF connector; The standards of other advanced countries include German DIN, British BS, Japanese JIS and IEC standards; Most of these national or international standards are formulated with reference to or equivalent to the U.S. military standards, and some countries or companies even directly apply the U.S. military standards.
