What is a coaxial connector, the basic structure, working principle, types, technical parameters, coupling mechanism, application and development status of coaxial connectors 1

Coaxial connector is a common connector used in electronic devices and communication systems to connect coaxial cables with equipment or other circuits. The AD9761ARS coaxial connector has excellent shielding performance and low loss characteristics, and is widely used in wireless communication, television, broadcasting, radar and other fields.diode

1、 Basic structure:

A coaxial connector consists of an outer conductor, an inner conductor, and an insulator. External conductors are usually made of metals such as copper, aluminum, or stainless steel. The inner conductor is usually a central lead and is also made of metal. Insulators are used to isolate outer and inner conductors, typically made of polytetrafluoroethylene (PTFE) or polyolefin materials.diode

2、 Working principle:

The working principle of coaxial connectors is based on the working principle of coaxial cables. A coaxial cable consists of an inner conductor and an outer conductor, with the inner conductor isolated from the outer conductor by an insulator. When signals are transmitted through coaxial cables, electric and magnetic fields are generated between the inner and outer conductors, thereby achieving signal transmission. The function of coaxial connectors is to transmit signals from coaxial cables to equipment or other circuits, or to transmit signals from equipment or other circuits to coaxial cables.diode

3、 Type:

Coaxial connectors can be classified into the following types based on their connection methods and structural characteristics:

1. BNC connector (Bayonet Neill Concelman Connector): This is a common coaxial connector based on the principles of axial insertion and rotational locking. It is suitable for applications with a frequency range of 0Hz to 4GHz and is commonly used in fields such as video surveillance and computer networks.diode
