Flat Flexible Connectors (FFC, and Flat Printed Connectors, FPC) are an electrical connector used for a wide variety of applications. They are typically used to connect components in small electronic devices, such as cell phones, computers, and consumer electronic products. FFC connectors are ideal for applications that require a thin, low-profile, and low-cost solution for connecting two components or devices.

Types of FFC, FPC Connectors

FFC and FPC connectors are available in different sizes and configurations, with different pitch sizes (distance between rows of contacts) and terminal numbers. They may be single ended, double ended, or edge card styles. There are also several different styles of connector, such as latch type, individual strand type, locking type, IDC type, and insulation displacement type.

The major difference between FFC and FPC connectors is the construction of the contact. FFC connectors use a flexible flat contact that can be folded, while FPC connectors have rigid flat contacts. FPC connectors are also slightly thicker than FFC connectors, and usually require soldering. FFC connectors are typically used in lower-profile applications, where easily detachable connections are not required.

62674-121121 Application Field and Working Principle

The 62674-121121 FFC / FPC Connector is a 2.0mm pitch connector, with 20 positions in one row. It is available in both FFC and FPC configurations. It has a 50 micro inch gold plated surface, with a maximum operating temperature of 105 degrees Celsius. Its primary application field is audio / video / digital signal connections in home appliances, such as LCD TVs and DVD players. It is also used for mobile phone / PAD / digital camera / printer connections.

The FFC / FPC connector is fundamentally different from ordinary connectors. It does not require a contact, insulation or solder for electrical connection. Instead, electrical connection is achieved through interdigitation between the two contacts. When two connectors are mated, each contact spring pushes outwards and interlocks to hold the two connectors in place.

The FFC / FPC connectors offer several advantages over conventional connectors. First, their contact construction eliminates the possibility of short circuits or poor contact resistance due to misalignment. Second, their thin profile allows them to be used in small spaces. Third, their low cost makes them an attractive solution for low-volume applications. Finally, their quick mating times make them ideal for high-speed automated applications.

Conclusion

The 62674-121121 FFC / FPC Connector is an electrical connector designed for a wide range of applications. It offers several advantages over conventional connectors, including a thin profile, low cost, and quick mating time. It is primarily used in audio / video / digital signal connections in home appliances, such as LCD TVs and DVD players, as well as for mobile phone / PAD / digital camera / printer connections.
