FFC/FPC (flat flexible) connectors are used to reduce the costs of handling and designing electrical cables. Thanks to their flat design, these connectors provide a wide range of electrical and physical connection capabilities that can be used in numerous efforts such as wiring and testing. Connectors in this category are very versatile and can accommodate different configurations as well as a variety of cable types. It is essential to know more about application fields and working principles of these connectors.

Application Fields

FFC/FPC connectors are commonly used to build connections for cable harnesses, cable assemblies, interconnects, and wiring systems. They are commonly used in car manufacturers, medical, consumer electronics, and aerospace electronics. The connector is also used for connecting devices that have a circular opening such as panel-mount connectors.

FFC/FPC connectors are also commonly used in industrial and commercial applications. These connectors are used where high-speed, high-density connection points require a low profile. This means they are used when space is at a premium, while maintaining a reliable connection. The connector can also be used in applications where harsh environments or wide temperature ranges are encountered.

In addition, FFC/FPC connectors are used to connect a variety of external components such as sensors and actuators. Sensors measure conditions such as temperature, pressure, and even sound and can be used for multiple purposes, and actuators can control pumps, motors, or valves. Since these external components need to be connected to internal wiring, flat flexible connectors need to be used for this purpose.

Working Principles

FFC/FPC connectors use a dual contact method that consists of two parts. The first part is the contact itself, which is generally a flat contact finger, and the second part is the contact holder, which is used to contain and position the contact. The contact holder can be a flexible film, a rigid frame, or a non-metallic support structure.

The FFC/FPC contact fingers have a dual cantilever design, which is used to provide improved contact retention, and a spring force to ensure excellent electrical performance. The contacts are preloaded against the contact holder to provide high contact pressure, which helps to ensure reliable contact. These contacts are typically made of copper, but other materials can also be used.

In addition, the FFC/FPC connector is designed to provide a reliable connection between mating parts. It is designed with a cabling path that is low-profile and space-saving by eliminating the need for large bends or round wires. Moreover, its construction ensures minimal contact damage from the environment, such as moisture and shock.

Conclusion

FFC/FPC connectors are widely used in various industries due to their many features. They are designed to provide improved electrical performance, reliable connections, and a low-profile space-saving design. Moreover, FFC/FPC connectors can be used to connect external components such as sensors and actuators, and are used in environments with wide temperature ranges.Knowing the application fields and working principles of FFC/FPC connectors can help you choose the right connector for your needs.
