Introduction to Coaxial Connectors (RF)

There are numerous types of cable connector, and coaxial connectors (RF) are one of the most popular and widely used. A coaxial connector is commonly used in radio frequency (RF) equipment and systems, providing a connection between two cables. The connectors are designed to maintain a strong electrical connection, even under harsh conditions.

142178 Application Field and Working Principle

The 142178 application field is specifically designed for installation within telecommunication equipment. It is a coaxial connector used to couple two coaxial cables and provide a solid electrical link. It has a pin and socket body that interconnects with a couple nut for mounting and strain relief. The connector is constructed of copper with nickel plating and a gold plating on the connector tips.The 142178 is designed to handle frequencies up to 4 GHz. It is equipped with a double-beam contact, ensuring a reliable electrical contact and minimal power loss across the connection. It is a precision connector that operates without requiring extra force or soldering. When properly installed, the 142178 ensures a tight connection with consistent integral shielding.The design and construction of the 142178 are based on a principle commonly known as "the coaxial impedance matching". This means that the coaxial connector ensures the impedance of the line stays constant throughout the transmission by providing consistent electrical characteristics. The connector is fitted with a center pin that aligns with the center conductor of the cable, resulting in the uniform impedance of the line. This eliminates signal reflection caused by impedance mismatch.

Conclusion

The 142178 coaxial connector is a reliable and versatile solution for installation within various types of telecommunication equipment. It is designed to maintain a tight electrical connection and ensure consistent electrical characteristics of the line. The connector is fitted with a double-beam contact and uses a center pin that is aligned with the center conductor of the cable, allowing for an impedance matching of the line and eliminating signal reflection.
