Connectors are electronic components used to establish electrical connection between electronic devices. They can be divided into many types according to their structures, functions and uses, and are widely used in various fields. The following are some common connector types and their application fields:

Classify connectors:

Circular connector: This kind of connector usually has a circular shape, which is suitable for military equipment, aerospace equipment and industrial equipment and other scenes that need durable and reliable connection.

Rectangular connectors: Rectangular connectors are usually used in computer equipment, industrial control systems and automotive electronics, which require high-density connections, easy installation and greater power transmission.

Board-to-board connector: it is mainly used to connect two printed circuit boards, such as computer internal components, communication equipment and consumer electronic products.

Edge connector: The pin of this connector is located on its side, which is common in the connection between computer motherboard and expansion card.

Wire-to-board connector: used to connect wires to printed circuit boards, widely used in power supply, signal transmission and other fields.

Coaxial connector: used to transmit radio frequency signals, often used in wireless communication, television and broadcasting equipment.

Fiber connector: specially designed for optical fiber communication system, used to connect optical cables between optical fibers.
