Coaxial Connectors (RF)

Coaxial connectors are a type of connector used to provide electrical connections for radio frequency (RF) signals. There are various types of connectors, with each having different features and advantages. One of the most common is the UM-QR-1(40) connector, a coaxial connector used for RF applications. In this article, we\'ll discuss the application fields and working principle of the UM-QR-1(40).

Applications of UM-QR-1(40)

The UM-QR-1(40) connector is used for a variety of applications, such as in cellular phones, Wi-Fi routers, and television distribution systems. It is also used in satellite and terrestrial radio Frequency (RF) systems, High-speed Ethernet systems, and infrared home control systems. Due to its robust design, it can also be used in aerospace and military environments where vibration or shock may be present.

Construction of UM-QR-1(40)

The UM-QR-1(40) connector is constructed of two concentric metal cylinders. These cylinders are separated by an insulating paste or fiber material, which can vary depending on the specific version, and the interior of the connector is filled with air. The outer cylinder is known as the outer conductor, and serves to protect the inner conductor from interference, as well as providing a ground connection for the RF signal. The inner conductor is composed of a solid center pin surrounded by a dielectric, which is separated from the outer conductor by an insulator.

Working Principle

When the UM-QR-1(40) connector is plugged in, the inner conductor creates a connection with the outer conductor, forming an enclosed antenna. The metal shielding obtains a connection with ground, while the inner conductor maintains a connection with the center pin. This allows the RF signal to be conducted through the center pin uninterrupted and shielded from interference.

Conclusion

The UM-QR-1(40) connector is a versatile and durable RF connector that is suitable for a wide range of applications. It is constructed of two concentric metal cylinders that are separated by an insulating material, with the inner conductor creating a connection with the outer conductor when the two are plugged together. This provides an enclosed antenna, which allows the RF signal to be conducted through the center pin uninterrupted and shielded from interference. As such, it is a reliable and effective and connector for use in both consumer applications and in more demanding environments.
