There are many types of connectors, such as circular connectors, RF connectors, rectangular connectors, SMB connectors, BNC, etc.

Circular connectors are a type of connector widely used in aerospace equipment connections, also known as aviation plugs. RF connector is a special type of coaxial connector used in high-frequency radio applications. It uses multiple wires wrapped around a core wire for shielding. A rectangular connector is a type of connector with a simple structure and convenient installation, commonly used in communication equipment, computer equipment, and other fields.

SMB connector is a small push lock RF coaxial connector with the characteristics of small size, light weight, convenient use, and excellent electrical performance, suitable for connecting high-strength coaxial cables. It can connect wireless devices and E1 transmission cables on the base station side to achieve data transmission and signal transmission. BNC is a bayonet type RF coaxial connector with the characteristics of fast connection and reliable contact, widely used in the field of wireless equipment and electronic instruments.
