FFC, FPC (Flat Flexible) Connectors

Flat Flexible Connectors, or FFC/FPC, are a type of electrical connector compatible with a variety of electronic devices. These connecters allow for more effective and efficient communication between these electronic devices. The applications, structures and working principles of SFW21R-3HS FFC/FPC Connectors will be discussed in further detail in this paper.

Applications

FFC/FPC Connectors are a great choice for connecting electrical components in even the most challenging engineering applications. Because they are so thin and flexible, FFC/FPC Connectors can easily fit into small spaces or fit around other components, making them popular for use in complex projects where space is limited. Some of the most common uses for FFC/FPC Connectors include connecting LCDs to PCBs, providing electrical connections in handheld devices, and helping to ensure efficient connections between components in computer systems and other electronic devices. Additionally, these connectors are well-suited for use in any application that requires a fast and reliable connection.

Structures and Contacts

SFW21R-3HS FFC/FPC Connectors feature an integral solid white plastic housing with a black plastic shield. The housing is designed to keep the contacts of the connector safe from external contaminants.The FFC/FPC Connector has a total of three contacts that are placed within the housing in a row. The contact at the center is a standard 2mm flat pin, while the contacts at either side are made from flexible flat conductors. This connector is also equipped with a soldering tab for easy installation.

Working Principle

To understand how an SFW21R-3HS FFC/FPC Connector functions, it is important to first understand the difference between FFC and FPC Connectors. FFC stands for Flexible Flat Cable and is a type of cable that is composed of a ribbon of multiple insulated conductors. This type of cable is generally used in applications where the need for flexibility outweighs the need for robustness or high current carrying capacity. On the other hand, FPC stands for Flexible Printed Circuit and is a type of printed circuit board that is composed of multiple conductive traces on a thin, flexible substrate. This type of printed circuit board is usually more robust than FFC and has a high current carrying capacity.

In an SFW21R-3HS FFC/FPC Connector, the contact at the center is a standard 2mm flat pin that is designed to establish an electrical connection between the two ends of the connector. The two contacts on either side of the center pin are flexible flat conductors (FFCs) that are designed to ensure a secure, low-resistance connection. When the connector is plugged in, the two FFCs are pressed together and the physical contact between them ensures that an electrical connection is established.

Conclusion

Flat Flexible Connectors, or FFC/FPC Connectors, are a type of electrical connector that are compatible with a variety of electronic devices. The SFW21R-3HS FFC/FPC Connector features an integral solid white plastic housing that protects the contacts within the connector. It also has three contacts- a standard 2mm flat pin at the center, and two flexible flat conductors (FFCs) at either side. When the connector is plugged in, the FFCs are pressed together and the physical contact between them ensures that an electrical connection is established.

FFC/FPC Connectors are perfect for connecting electrical components in even the most challenging engineering applications. Because of their thin and flexible construction, FFC/FPC Connectors can easily fit into small spaces or fit around other components. They are popular for use in complex projects where space is limited and are especially well-suited for applications that require a fast and reliable connection.
