Flat Flexible Connectors, commonly known as FFC or FPC connectors, are widely used in a wide range of applications for a number of different purposes. This article seeks to identify and analyze the various types of these connectors, along with their application field and working principle.

Type A: The basic form of this type of connector is a flat plastic strip or a flat ribbon cable with metal pins along the edges. The pins are arranged in rows and grouped in sets, with each set corresponding to a set of electrical connections between the components. These pins have a large contact area and can carry a large amount of current, making them suitable for use with high-power devices. The pins are held in place by a tension clip, which is connected to the end of the connector. The clip is designed to provide a secure connection between the connector and its contact surface.

Type B: This type of connector uses a different type of contact. Instead of the pins, this connector uses a thin strip of metal that is embedded in the plastic ribbon. This strip of metal can be bent or deformed to make contact with different surfaces. The metal strip is held in place by a special adhesive and is not easily disconnected. This type of connection is often used in applications where very small and delicate components need to be connected, as the contact can be made without the need for any manual intervention.

Type C: This type of connector uses a combination of the above two. This type of connector combines a plastic strip and a metal strip to create a more secure connection. The metal strip is embedded in the plastic ribbon and is usually attached to the termination pins of the connector. This connection is ideal for high power and delicate components, as it ensures a proper connection and a secure electrical connection.

The application field and usage of the FFC or FPC connectors is often dependent on the specific environment and needs of the user. For instance, these connectors can be used in telecommunications systems, fire alarm systems, medical equipment, automotive wiring systems, and other areas. Additionally, they are also used to connect various types of components to a main circuit board. These connectors are also suitable for connecting electrical components that require a higher voltage, high resistance, and/or high power.

The working principle of the FFC or FPC connectors is basically the same as that of the other types of connectors. A tension clip is connected to the end of the connector and two metal strips or pins are made contact with a component. The contact is then held in place by a plastic ribbon or a thin metal sheet. Once the connection is made, electrical signals can pass through the connection and are usually routed to and from the main circuit board. This establishes an electrical connection and enables the device to function properly.

In conclusion, FFC or FPC connectors are widely used in a variety of applications and environments. They are great for connecting components that require high voltage, high resistance, and/or high power. They are also suitable for connecting very small and delicate components. Additionally, they are very reliable and secure, making them an ideal choice for various applications. When used in addition to other types of connectors, these connectors can also help to ensure an efficient and reliable communication between components.
