What are the categories and uses of connectors?

I. Connector classification and use are how? 1. concentric connector: concentric connector is a small plug-seat connector, its small size and the function of both switch. Concentric connectors for low-frequency circuits, mostly used in headphones, microphones and external power supply wiring. 2. strip type connector: strip type connector lead number is generally dozens of the following, for printed circuit boards and devices in the device circuit connection. 3. printed circuit connectors: printed circuit connectors are mainly used in electrical equipment or electronic equipment to connect printed circuit boards. 4. Ribbon cable connectors Ribbon cable connector: the socket of the ribbon cable connector is directly welded to the printed circuit board, the plug and ribbon cable using puncture crimping, can be completed at once, reliable contact, easy to use, suitable for instrumentation circuit connection. 5. Circular connectors: circular connector plugs, sockets are mostly threaded connections, the terminals can be ranging from two to hundreds of different, with a small size, high reliability, can meet the Rectangular connectors: rectangular connectors in the plug, socket using threaded guide bar connection, and locking device, mainly used for electronic equipment, intelligent instrumentation and electronic control equipment, electrical connections.7. Water pressure sealing connectors: this connector is mostly circular connectors, suitable for circuit connections in water or harsh environmental conditions.8. Radio frequency coaxial Connector: RF coaxial connector is a small threaded connection locking connector, with a small size, light weight, easy to use and so on, suitable for radio equipment and electronic instruments in high-frequency circuits for the connection of radio frequency cables. Its operating frequency is generally up to 500MHz.
