Coaxial Connectors (RF): 031-70221 Application Field and Working Principle

Coaxial connectors are one of the most popular types of RF connectors, used in radio applications ranging from commercial to military frequencies. The 031-70221 coaxial connector is designed for use in high voltage and switching applications in a wide range of frequencies. This article will explain the working principle of 031-70221 connectors and its application field.

Working Principle

Like all other coaxial connectors, the 031-70221 has two components: an inner conductor and an outer conductor. The inner conductor is a piece of metal, usually made of copper, that carries the electrical current. The outer conductor is a conductive case that surrounds and shields the inner conductor for maximum signal transfer. The two components are held together by an o-ring seal that is compressed mechanically to make a connection.

The 031-70221 coaxial connector has a unique design that not only provides a connection between two devices but also offers several other advantages. The integrated strain relief design reduces stress from pulling or bending on the wires, protecting both the conductor and the connector itself. The wide range of clamping threads ensures a secure fit between the connector and the cable, and the insulation helps protect against shorts and interference. Finally, the design of the 031-70221 connector allows for high voltage and power rail applications up to 20kV.

Application Field

The 031-70221 coaxial connector is designed for RF and microwave applications that require high voltage and power switching in a wide frequency range. It is commonly used in aircraft, defense, communications, and broadcast systems. Its high-power capabilities, combined with its rugged construction and its wide range of frequencies, make it the ideal choice for applications where high voltage, high-power and reliability are paramount.

The 031-70221 is also suitable for use in digital and mixed signal applications, such as in computers and in medical equipment. It is compatible with many popular coaxial cable types, including RG-62, RG-179, and RG-316. It is approved by the IEC, CE, and RoHS.

Conclusion

The 031-70221 coaxial connector is an ideal solution for high voltage and power applications in a wide range of frequencies. Its unique design provides a secure fit between the connector and the cable, while also providing strain relief and protection from shorts and interference. It is suitable for use in aircraft, defense, communications, and broadcast systems, as well as in digital and mixed signal applications in computers and medical equipment.
