Coaxial Connectors (RF)

A coaxial connector, also known as an RF connector, is a type of electrical connector designed to work at radio frequencies in the multi-megahertz range. These connectors come in various sizes, shapes, and designs and are used to terminate a coaxial cable in order to transmit signals. The most common coaxial connectors used today are the UM-QPJ-1.5-5 connectors, which are used in applications such as wireless communications, broadcast television, radar systems, avionics, and medical imaging.

UM-QPJ-1.5-5 Application Field

UM-QPJ-1.5-5 coaxial connectors are designed for use in telecommunications, broadcast TV, radar, avionics, and medical imaging. They are a popular choice for applications requiring a low voltage, up to 200 volts. They are designed to deliver reliable, secure connections with a high level of signal integrity. These types of connectors offer excellent signal quality, low crosstalk, and low insertion loss. The combination of good signal quality and high reliability makes them an ideal choice for many applications. In addition, these connectors are well suited for applications that require flexibility in terms of size, impedance, and frequency.

Working Principle of UM-QPJ-1.5-5

In general, UM-QPJ-1.5-5 coaxial connectors are composed of two components – the center contact and the outer sleeve. The center contact is typically made of a solid material such as brass, copper, or aluminum. It is used to secure the center conductor, which is typically a stranded copper wire, to the rest of the connector. The outer sleeve is typically made of a conductive material such as aluminum, brass, or copper. This sleeve provides additional shielding to the center conductor from any external interference.

The center contact and the outer sleeve are usually connected to the mating connector via a spring-loaded contact, which creates a secure, reliable connection. The spring-loaded contact also helps to reduce the insertion loss of the connection, which can occur when the connector is removed from its mating half during installation or removal. The spring-loaded contact also helps to reduce the impact of any environmental variations on the signal quality.

In addition, the center contact of an UM-QPJ-1.5-5 connector is designed for reliable engagement and disengagement with the corresponding connector with a minimum of wear or damage. This is due to the design of the center contact, which is constructed to have a low contact resistance in order to facilitate better connection when the connector is mated and un-mated.

The outer sleeve on the UM-QPJ-1.5-5 is designed to provide maximum shielding for the signal while still allowing the connector to be inserted and removed easily. The shielding of the outer sleeve is further improved by the use of conductive gaskets, which are placed between the outer sleeve and the mating connector to provide better protection for the signal.

Conclusion

The UM-QPJ-1.5-5 coaxial connectors are a popular choice for applications requiring reliable and secure connections with a high level of signal integrity. With their low voltage, up to 200 volts, and excellent signal quality, low crosstalk, and low insertion loss, these connectors are well suited for a variety of applications—from telecommunications, broadcast TV, radar, avionics, and medical imaging.

The combination of the center contact, spring-loaded contact, and outer sleeve allows for a secure and reliable connection with low contact resistance and maximum signal shielding. This makes the UM-QPJ-1.5-5 a very efficient connector, which will last through many cycles of insertion and removal.
