Coaxial Connectors, also known as RF (Radio Frequency) Connectors, are used in many of the world's leading industrial applications. The forms of these connectors are specially designed for connecting multi-shielded coaxial cables used for radio broadcasting, broadcasting and communications. As an example, 138-4407-007 coaxial connectors are one of the most commonly used in this sphere.

Application Fields

Coaxial Connectors, particularly the 138-4407-007, are commonly used in communication systems to connect two devices that are adapted to the same frequency or to link two coaxial cables together. This type of coaxial connector is typically used in HF, VHF and UHF radios, antennas, coaxial networks and antennas. It's also used in various fields such as professional radio and audio, professional video, audio and video monitoring, digital TV head-end and CATV.

Working Principle

138-4407-007 coaxial connectors are used to transfer electrical and optical signals between two different circuits. The two circuits are usually connected through the same type of coaxial connectivity. The basic technology is a solid core surrounded by a conductive shield, providing for the lowest amount of resistance and longest path for energy to travel down the wire. A nut and ferrule are then used to attach the connector to the cable end, securing it in place. It's important that the nut is correctly tightened to ensure a proper connection.

The contact between the two pieces of the coaxial connector has a few different parts. One of these is the contact pin, which is designed to provide a positive and reliable connection. The contact pin is usually made of copper or brass and the actual contact surface is slightly tapered which helps ensure the best contact. The contact has several components to make the connection with, including the gasket, spring and a washer.

To ensure a good connection, the coaxial connector can be either soldered or crimped. Soldering is considered to be the best and most reliable method, as the contact point is effectively sealed, ensuring a strong electrical connection. With crimping, the contact is not sealed as with soldering, but still provides a connection just as strong. Crimping is more commonly used because it is often faster and cheaper. It is important to make sure the correct tool is used to crimp or solder the coaxial connector.

Conclusion

The 138-4407-007 is widely used in communication systems due to its small size and low cost. It is designed for connecting multi-shielded coaxial cables used for radio broadcasting, broadcasting, and communications. As with all coaxial connectors, the most important components that need to be considered are contact pins, seals, nuts, and ferrule. The contact between the two pieces of the coaxial connector is usually made through soldering or crimping. Utilizing the correct tools, the 138-4407-007 can be easily and properly installed into a wide variety of Radio Frequency (RF) connections.
