FFC, FPC (Flat Flexible) Connectors - Contacts

Flat flexible contacts, otherwise known as FFC or FPC (flat flexible cables) connectors, are widely used in a variety of applications due to their small size, cost effectiveness, flexibility, and reliable operation. FFC/FPC connectors are best suited for use in limited space applications or where flexibility is required.

Applications of FFC/FPC Connectors

FFC/FPC connectors are used in a variety of applications ranging from consumer electronics to automotive and aerospace applications. Common applications include cell phones, digital cameras, PDAs, GPS receivers, satellite equipment, test and measurement equipment, computer peripherals, and medical devices. FFC/FPC connectors are also used in the aerospace and automotive industries to interconnect sensors, antennae, switches, and electrical components. The flexibility of the flat cable allows it to be routed around obstacles or through tight spaces. Additionally, the use of flat cables eliminates the need for expensive, environmentally hazardous wire harnessing.

Structure and Working Principle

Most FFC/FPC connectors consist of two mating plastic housing pieces, forming a single unit. When inserted into the mating components, the contacts press against the mating surface to form a secure electrical connection. These contacts are typically made of gold-plated copper, but can also be made from brass-plated nickel or other metals. The contacts are connected to the FFC/FPC cables via special contact-terminations, which provide superior electrical connection reliability. The two mating components of the FFC/FPC connectors are typically held together by latching systems. For instance, latch locks can be used to securely hold the two parts together. Additionally, many FFC/FPC connector designs feature a locking tab to ensure the connector stays in place, even under high vibration conditions.

Advantages of FFC/FPC Connectors

FFC/FPC connectors are popular due to their smaller form factor, flexibility, and robust construction. Furthermore, with fewer potential points of failure, these connectors provide increased reliability when compared to traditional connectors. Additionally, FFC/FPC connectors offer increased durability and can withstand higher vibration and shock levels when compared to traditional connectors. Finally, FFC/FPC connectors require minimal space and offer much better flexibility for routing cables in tight spaces.

Conclusion

In summary, FFC or FPC (flat flexible contact) connectors are a reliable and cost-effective solution for many applications where space is a limiting factor. These connectors are particularly well suited for use in limited space applications or where flexibility is required. Furthermore, FFC/FPC connectors can provide excellent durability and reliability for applications in the consumer electronics, automotive, and aerospace industries.
