Introduction to Circular Cable Assemblies

Circular cable assemblies (CCAs) are a specific type of cable that are primarily used in applications where the highest degree of mechanical protection, environmental resistance, and EMI/RFI shielding are required. CCAs are commonly found in aerospace and military applications, healthcare equipment, robotics and automation systems, and automotive systems.

What Is A Circular Cable Assembly?

A circular cable assembly (CCA) is a type of connector that is cylindrical in shape and designed to meet the most rigorous environmental requirements. CCAs provide strong physical protection from a range of environmental conditions, while also offering protection from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). CCAs employ a variety of shielding materials such as aluminum, braid, or insulated jackets. These cables use a circular-shaped connector to create a secure, corrosion-resistant, and waterproof connection. The contact termination used in the assembly is highly reliable and has a low electrical resistance compared to other types of connections. The circular connector also provides superior strength and durability.

Applications for Circular Cable Assemblies

Circular cable assemblies are commonly used in a wide variety of applications, including industrial, aerospace, military, medical, and automotive applications. CCAs are used in environments where environmental conditions are harsh, including extreme temperatures, high pressures, and high levels of humidity and dust. In aerospace and military applications, CCAs are often used due to their unique combination of durability and EMI/RFI shielding. They are often found in aircraft, missiles, ground vehicles, battle tanks, and naval aircraft. In healthcare equipment, robotic and automation systems, as well as automotive applications, CCAs are often used because of their ability to provide a secure connection in a confined space.

Working Principle of Circular Cable Assemblies

The working principle of a circular cable assembly relies on a contact interface in the assembly. Typically, the contact interface will include a pin on one end, which is then mechanically secured in a round hole in the opposite end of the contact. This creates a secure connection and minimizes any chance of arcing. CCAs also use specialized seals to provide an environment safe from dust and moisture. In addition to these seals, CCAs use a number of shielding materials such as aluminum, copper, braid, and insulated jackets to reduce the effects of EMI and RFI. The combination of a secure connection and shielding makes CCAs ideal for high temperature, high pressure, and high electrical demand applications. The round connector design makes CCAs also suitable for industrial applications in production processes, field wiring, and control systems.

Advantages of Circular Cable Assemblies

The use of circular cable assemblies offers many advantages, including the following:

• Strong mechanical protection from harsh environments
• EMI/RFI shielding to reduce interference
• Low electrical resistance and superior strength for secure connections
• A variety of shielding materials for superior protection
• High temperature, pressure, and electrical demands
• Ideal for industrial applications where space is limited

Conclusion

Circular cable assemblies have become increasingly popular in recent years due to their ability to provide a secure connection in confined spaces. They also offer strong mechanical protection, EMI/RFI shielding, and superior strength for industrial applications such as robotics, automation systems, healthcare equipment, and aerospace and military applications. As technology continues to develop, CCAs are likely to remain a staple of the industry, especially in applications where a secure connection and reliable performance in a variety of environments are required.
