Introduction

FFC, FPC (flat flexible) connectors are a type of electrical connectors used in a wide variety of industries, such as aviation, automotive, consumer electronics, and telecoms. The XF3H-3555-31AR connector is a FFC, FPC style connector designed for use in high density applications. This section will discuss the application field and working principle of this connector system.

Application Field

Due to its small form factor and high reliability, the XF3H-3555-31AR connector is suitable for a variety of applications. In the aviation industry, this connector can be used to connect avionics components, such as transceivers, GPS antennas, and navigation aids. In the automotive industry, it can be used to link onboard electronic systems, such as sensors, actuators, and ECU’s. Additionally, it can be used for a range of wireless communication applications, such as Bluetooth, cellular, and Wifi. Finally, the XF3H-3555-31AR connector can also be used in consumer electronics, such as smart phones, tablets, and digital cameras.

Working Principle

The XF3H-3555-31AR connector is composed of two parts; a male and female part, which form a gas-tight connection when mated. The male part is composed of a series of flush pins, while the female part consists of a pattern of contact fingers. When the two parts are mated, the pins on the male part make contact with the female part’s fingers to form an electrical connection. The connection is held in place by a spring which applies a small force to keep the electrical contact from loosening. Additionally, the gas-tight seal of the connection prevents dirt and dust from entering the connection, maintaining the quality of the connection over the life of the connector.

Conclusion

The XF3H-3555-31AR connector is an FFC, FPC style connector that is suitable for a wide variety of applications, including aviation, automotive, consumer electronics, and wireless communication. This connector features a reliable and high density connection that is held in place by a spring force and is gas-tight to prevent dirt and dust from deteriorating the connection.
