Coaxial Connectors (RF)

Introduction

Coaxial connectors, also known as RF connectors, are an important type of electrical connectors. They are widely used in a variety of audio and video equipment, radio frequency, military, avionic, and telecommunication applications. Coaxial connectors typically consist of a central conductor, an insulating dielectric material, an outer shield (or ground) and a protective covering.

172373 Application Field and Working Principle

The 172373 applications field includes broadcasting, satellite, cable television, microwave communication, and outdoor base stations. The 172373 series of coaxial connectors are extremely versatile in the range of applications they are suitable for. These connectors are used for legacy coaxial cable and for applications where 4-hole rectangular RFI connection is required. The 172373 connectors, due to their unique design, provide excellent electrical performance while also maintaining very good mechanical durability over extended periods of time.

The working principle of the 172373 series of connectors is based on the use of screw-on coupling. An outer shell with two bayonet or wrench-style fasteners and two inner contacts with a threaded center sleeve form the mechanical connection. This provides an electrical connection between the mating connectors, and the coupling nut connects the inner contact of one connector to the outer shield of the other. Electrical continuity is maintained by an O-ring inside the coupling nut that provides a seal between the inner contact and the outer shield.

Advantages

The 172373 series of coaxial connectors is known for its durability and reliability in a variety of applications. These connectors are designed to meet most MIL-SPEC requirements for environmental durability. The 172373 series also offers superior electrical and mechanical performance with low insertion and return loss, excellent shielding, corrosion resistance, and excellent electrical performance over frequency ranges of 0-4 GHz. In addition, these connectors are economic with reduced costs due to their simple and reliable design.

Disadvantages

The 172373 series of connectors requires a great deal of time and effort to properly install and secure. These connectors require disassembly and reassembly of the connectors in order to fit them into the system. Additionally, the coupling nut should be properly tightened to ensure reliable connection. This can require specialized tools to achieve secure connections. Furthermore, the outer shells of these connectors are somewhat rigid and can be difficult to work with if the connector is not properly secured.

Conclusion

The 172373 series of coaxial connectors is an extremely versatile and reliable connector. With its durability, reliability and excellent electrical performance, this series of connectors is great for many different applications. While they can be somewhat time-consuming to install, the reliability they bring is certainly worth the extra effort.
