How can Canted Coil Springs used for electrical contacts/conductivity?

Canted coil springs, also known as slanted coil springs, are not only used in mechanical applications like locking, holding, connecting purposes, but also applications in the electrical conductivity aspect, particularly in electrical contacts. These springs are known for their unique design, offering a predictable load in both linear and angular deflections.

Here's how canted coil springs can be used for electrical contacts:

1. Electrical power transfer design:

•     •   Canted coil springs can be designed for electrical conducting purposes to provide a reliable and consistent electrical connection.
•     •  The canted coil spring's unique oval shape allows for flexibility and compliance, making it suitable for maintaining electrical contact points under uneven surfaces, presence of vibrations and shocks, or other dynamic factors.
•     •  The canted coil spring's design allows for the precise control of contact pressure, ensuring optimal electrical conductivity without causing excessive wear on the contact surfaces.

2. Force Control:

The special shape of canted coil spring is designed to have a precise control over the load applied during contact. This is important in electrical applications where often a specific force is required to establish and maintain a consistent electrical connection. The spring’s ability to provide constant load ensures consistent performance over time.

3. Vibration and Shock Resistance:

Canted coil springs can accommodate vibrations and shocks conditions, making them suitable for applications where consistent electrical contacts are needed to withstand mechanical disturbances.

This characteristic is vital in applications such as connectors in aerospace, automotive, semiconductor, and other industrial environments.

4. Durability and Longevity:

The material of the canted coil spring, often stainless steel, provides durability and resistance to corrosion. Other materials such as sliver or BeCu Beryllium copper also have excellent electrical conductivity that is essential for maintaining electrical performance over an extended period.

5. Temperature Stability:

The materials used for canted coil springs, such as stainless steel, elgiloy, copper, can withstand a wide range of temperatures, making them suitable for applications where there are temperature variations.

6. Customization:

Canted coil springs can be customized to meet specific requirements. The spring load can be adjusted according to the dimension, welding techniques, axial or radial compressions, making them adaptable to various electrical contact designs.

7. Applications:

Canted coil springs may be used in electrical connectors, switches, relay contacts, EV charging equipments and other components where maintaining a reliable electrical connection is essential.

In summary, canted coil springs are suitable for electrical conducting applications due to their unique design geometry, including consistent contact with the surface, vibration and shock resistance, durability, and temperature stability... and more. They play a vital role in ensuring the reliability and longevity of electrical connections in various industries.
