FFC, FPC (Flat Flexible) Connectors

Flat flexible connectors (FFC/FPC) are used primarily for connecting circuit boards together in electronic products. They provide electrical connections between components on circuit boards while ensuring flexibility and reliability in the assembly and test of boards. The connectors feature low profile, compact design for space savings, low-profile flexible flat cables (FFCs) with low twist-coiling feature for reliable connection and minimal drag when the board is tested. They are available in a variety of colors and lengths, enabling designers to achieve the required electrical and mechanical performance for their application.

0520302929 Application Field and Working Principle

The 0520302929 series of FFC/FPC connectors provide robust electrical connections while maintaining high flexibility and reliability. The connectors feature a modular design that allows for various types of combinations including hook-and-loop fasteners, ribbon cables, flatbed cables, and IDC/ribbon cable adapters. The series consists of two types of connectors, a straight and a pitch-shifted mating type, to accommodate the various applications. The hook-and-loop fasteners are designed to allow easy disconnection and connection for quick maintenance and assembly. The maximum current rating is 6A, and insulation resistance values exceed 10¹² ohms.

The working principle of the FFC/FPC connectors is simple. When two circuits are connected, the pitch-shifted and straight version of the connector compliment each other on the two board side surfaces, aligning the connector pins so that electrical connection is made. The pitch-shifting is due to the power back and flow of current in the circuit board, which causes a slight turn. The pins on the connector then accept the mating non-teeth slots on the opposite board\'s connector, providing the electrical connection.

The FFC/FPC connectors provide reliable electrical connections and feature low profile, compact designs. The low profile allows for space savings and makes it easier to access and utilize the board assemblies. The flexible flat cables provide reliable connections and low twisting coiling feature for minimal drag when the board is tested. The connectors are available in a variety of colors and lengths, allowing design engineers to choose the required electrical and mechanical performance for their application.

FFC/FPC connectors are used across a wide range of industries and applications, from consumer electronics to automotive, medical, and industrial applications. The connectors are designed to meet IEC/EN 61000-4-5, UL60950, and RoHS safety standards, and have passed vibration and shock testing to ensure reliable performance. The connectors are available in a variety of configurations, including open, closed, and multiple pin pitch varieties, as well as 2.54 mm, 2.6 mm, and 3.0 mm pitch types. The connectors also feature temperature ratings of up to 105°C for improved reliability.

Overall, FFC/FPC connectors offer reliable electrical connections, with low profile, compact designs. The flexible flat cables offer low drag when tested, and the connectors are available in a variety of colors and lengths. The connectors provide reliable performance in a variety of industries, and can be custom configured for any application.
