Coaxial Connectors (RF): 72999 Application Field and Working Principle

Coaxial connectors, widely known as RF connectors, are a type of specialized electrical connectors used mostly for carrying analog and digital signals with a heavy reliance on radio frequencies or digital communication protocols. This type of connectors is primarily used in the industry for cable to board, cable to antenna, and board to board connections.The 72999 series is one of the most popular RF coaxial connectors available today. It is a specialized connector designed to withstand the most demanding of environments and delivers exceptional performance at frequencies up to 8GHz. It is one of the key components in various applications, especially in satellite communications and military installations.The 72999 series connectors consist of a plug and a receptacle with a contact pin on either side. The contact pin on the plug is crimped onto the shielded coaxial cable which connects the two parts. The frequency range of these connectors is from 0.35GHz to 4GHz, with an insertion loss of less than 1dB from 0.35GHz to 4GHz for the crimp-type connectors. They are designed with a threaded coupling and are available in a variety of sizes ranging from 26.5mm to 50.5mm.In order to understand the working principles of the 72999 coaxial connector, let’s take a closer look at its structure and components. The connector utilizes a crimp-type method to attach the contact to the cable. This consists of a contact pin at the center of the connector and an outer sleeve, which are both crimped onto the cable. The contact pin has two copper rings at the end, which are in contact with the contact pin. The outer sleeve also has a copper sleeve, which is surrounded by an insulating material. In addition, there is a rubber gasket between the contact pin and the outer sleeve that seals out dust and water.When a signal is sent through the coaxial cable, it is conducted through the contact pin and the outer sleeve. The electrical energy passes from the contact pin to the outer sleeve through the copper rings at the end of the contact pin. The copper sleeve surrounding the outer sleeve acts as a shield against unwanted frequencies and dissipates any electromagnetic energy emitted from the connector. The rubber gasket helps to protect the contact pin and reduce the amount of dust and water that can enter the connector.In summary, the 72999 coaxial connector is a specialized connector made up of a plug and receptacle and designed to handle higher frequency signals with a frequency range from 0.35GHz to 4GHz. It is an ideal choice for applications involving satellite communications and military installations as it is designed to handle high frequency signals with excellent signal integrity. It utilizes a crimp-type connection to attach the contact to the cable and has a rubber gasket between the contact pin and the outer sleeve to protect against dust and water.
