31-371

Coaxial Connectors (RF), commonly referred to as RF connectors, are widely used in radio frequency (RF) applications. The 31-371 connectors are the most common RF connectors and are used in a variety of applications from low-powered consumer electronics to high-power transmitters. The basics of 31-371 connectors and their application field and working principle are discussed in this article.

The 31-371 connectors are circular, metallic connectors that are used to connect two pieces of coaxial cable together. They consist of a centre pin surrounded by a cylindrical metal body and an outer sleeve. The centre pin is typically the same size as the outer diameter of the coaxial cable, while the outer sleeve is typically larger than the outer diameter of the cable. These connectors are designed for low-loss RF signal transmission and are often used in consumer electronics, broadcast television, and high-power RF equipment.

The application field of the 31-371 connectors lies primarily in low-power consumer electronics. These connectors are commonly used in the connection of stereo systems, televisions, satellite receivers, and other related consumer electronic applications. The 31-371 connectors are also widely used in broadcasting and television transmitters. They are used to connect the transmitter to the antenna, as well as to other elements of the broadcast system, such as power dividers and combining networks. In addition, 31-371 connectors are also used in amateur and high-power radio applications, where their low-loss performance is important for efficient signal transmission.

The working principle of the 31-371 connectors is based on the principle of a coaxial transmission line. In this type of connection, one electrical conductor, called the inner conductor, is surrounded by a concentric shield, called the outer conductor. This creates an enclosed cylindrical path, in which the inner conductor acts as the signal conductor and the outer conductor acts as a shield. The advantage of this type of line is that it provides a low-loss transmission path, meaning that the signal is less likely to be attenuated as it travels through the line.

The 31-371 connector is designed to provide a low-loss connection between a transmitter and an antenna (or other elements of the broadcast system). In order to achieve this, the centre pin and outer sleeve must form a tight connection that minimizes the amount of RF energy lost through the connection. The outer sleeve is connected to the shield of the coaxial cable, while the centre pin is connected to the inner conductor. This ensures that the RF signal is not lost as it travels down the length of the cable. In addition, the outer sleeve of the connector is also designed to provide an effective RF shield, protecting the internal components of the cable from external interference.

The 31-371 connectors are an important component of any radio frequency system, and they are used in a variety of applications. From low-power consumer electronics to high-power transmitters, the low-loss performance of 31-371 connectors makes them a reliable and effective choice for any RF application.
