• Introduction

Flat Flexible (FFC) Connectors are a type of electrical connector that often connects printed circuit boards, displays, and other electronic components together. They are a popular choice for their quick connector to disconnect capabilities and are commonly found in products from cell phones and computers to industrial applications. A specific FFC connector is the SFV21R-2STE1HLF whose application field and working principle will be discussed in this paper.

• Application Field

The SFV21R-2STE1HLF is most commonly used in medical and consumer electronics. It is also frequently used in military and aerospace applications. In the medical field, it is used to connect electrical signals from medical devices such as imaging equipment, powered wheelchairs, and patient monitors. It is also used in an array of consumer electronics, such as gaming systems, smartphones, and laptop computers. In military and aerospace applications, the SFV21R-2STE1HLF is used to connect electronic features such as navigation systems, data collection, and communication equipment.

• Working Principle

The SFV21R-2STE1HLF connector consists of a pair of Terminator Plugs, a Crimp Socket, and an External Wiring Cable. The pair of Terminator Plugs are connected to the Crimp Sockets, which are then mated to the External Wiring Cable. When the male and female pins are inserted into their respective ports, the pins make contact with each other to establish an electrical connection.The crimping method is the most common way to attach the External Wiring Cable to the connector. This involves attaching a crimp socket to the end of the cable and inserting the pins of the connector into the sockets. Once the pins are inserted, a crimping tool is used to compress the socket and secure the connection.The SFV21R-2STE1HLF connector is capable of conveying high-frequency signals due to its low-loss design. This design allows it to offer superior performance in terms of signal integrity and electrical noise. Additionally, the connector is designed to be both waterproof and dustproof, providing reliable protection against external environmental factors.

• Conclusion

The SFV21R-2STE1HLF is a popular Flat Flexible Connector used in a variety of applications, including medical, consumer electronics, military, and aerospace. Its low-loss design offers high-frequency signal capabilities and is both waterproof and dustproof. Its easy-to-use crimping method allows for quick plugging and unplugging of the connector. This makes it a reliable choice for connecting electrical components in a variety of industries.
