1734742-6

Flat Flexible Connectors (FFC, FPC) are a type of cable connector used in the electronics industry, where a range of applications require tightly-coupled and highly reliable connections. The particular type of connector covered by this article is the 1734742-6 series, which are manufactured by leading international electronics suppliers. This article provides an overview of the features and applications of these connectors, as well as a description of the underlying principles of operation.

Connector Overview and Features

The 1734742-6 series is a range of FFC/FPC connectors that feature a two-piece design, with the base connector made from an insulated metal substrate and the cover made from rubber. This design makes it suitable for a variety of highly demanding applications, such as communication products, automotive systems, as well as consumer electronics. The use of insulation allow for high speed data transmission, with a transmission rate up to 5Mb/s. In addition, the of the connector is enforced by a locking ring, which ensures that the connection remains secure and reliable.

The terminal orientation can either be straight or angled, depending on the requirements of the application. The straight orientation is best used for applications that require high insertion/withdrawal frequency due to the convenient access to the pins, whereas an angled orientation is more suitable for applications with height constraints where space needs to be conserved.

Applications

The 1734742-6 series of FFC/FPC connectors has a wide range of applications in the electronics industry. In communication products, the connector can be used to connect motherboards and daughter boards, due to the high-speed data transmission and robust connection it provides. In automotive systems, the connector can be used to connect sensors, radios, display monitors and other electronic components due to its ability to withstand harsh environmental conditions. The connector is also commonly used in consumer electronics, such as digital cameras, smartphones, tablets and other handheld devices.

Working Principle

The 1734742-6 series of FFC/FPC connectors work by utilizing an insulation-displacement connection (IDC) system. This system involves pressing the two halves of the connector together, which causes the insulation surrounding the metal pins to be penetrated. This pierces the insulation, creating a low-resistance connection and electrically coupling the two components together. This allows for a reliable, low-resistance connection.

The locking ring also helps to ensure that the connection remains secure and that it is not broken under the mechanical and electrical stresses of the application. This is achieved by its wedge-shaped design, which mechanically locks the two halves together and provides lateral support to resist tension, vibration and other forces that may be present in the application.

Conclusion

The 1734742-6 series of FFC/FPC connectors are a reliable and effective type of cable connector used in a variety of applications. These connectors utilize an IDC system, which provides a low-resistance connection while also being shielded from mechanical and electrical stress by the locking ring. This makes them ideal for applications that require tightly-coupled and highly reliable connections, such as those found in communication products, automotive systems and consumer electronics.
