The Basic Structure Of The RF Coaxial Connector Includes

RF coaxial connectors are components that are housed in a cable or instrument and are used to electrically connect or separate electronic components of the transmission line. Is a mechanical and electrical integration of the series. Variety of all kinds of specifications, relying on the mechanical structure, so as to ensure the characteristics of electrical, and other low-frequency connectors are essentially different. RF coaxial connector parts processing for the majority of turning machine processing, assembly is more manual. Product updates are slow. Is an important component of electrical connectors, high technical requirements, is a labor-intensive products.

RF coaxial connector is a mechanical and electrical integration of electronic components. RF coaxial connector is installed in the cable or instrument within an electronic products, metal parts are generally made of copper material, the shell with lead brass, pin socket with beryllium bronze, with PTFE, that is, Polytetrafluoroethylene as an insulating material, the main coating is gold-plated, silver, nickel, plated ternary alloy and the like. Technical indicators are mainly characteristic impedance, insulation resistance, contact resistance, voltage standing wave ratio, insertion loss, third-order intermodulation class.

According to the definition of the RF coaxial connector it is a part of the transmission line, by which it can make the transmission system components (cable) connected or disengaged, it is different from the power connector, the power connector for low frequency (usually 60 Hertz) electrical signals, while the RF connector is used to transmit RF energy, the frequency range is very wide, up to 18 * 109 Hz / sec (18GHZ) or even higher. Typical applications for RF connectors include advanced radar, travel communications, data transmission systems and aerospace equipment.

The basic structure of the coaxial connector includes: the center conductor (positive and negative center contact); then, the outside is a dielectric material, or insulator, as if in the same cable; Finally, external contact. This outer part acts as a function of the outer shield of the cable, ie the transmission of the signal as a grounding element of the shield or circuit.
