Products in this family are interconnect products used in conjunction with Flat Flexible Cable (FFC) and Flexible Printed Circuit (FPC) materials, and are predominantly of the sort which perform a cable-to-board interconnect function, being mounted to a printed circuit board, and providing both electrical connection and mechanical retention for an inserted FFC or FPC cable.
FFC (Flat Flexible Cable) and FPC (Flexible Printed Circuit) connectors are specialized interconnect solutions designed to facilitate the connection of flat, flexible cables or circuits to a PCB (Printed Circuit Board). These connectors are essential in applications where space is limited, and flexibility is required. They work by providing a secure and reliable connection between the flexible cable or circuit and the rigid PCB, using a clamping mechanism that ensures electrical continuity. The basic operating principle involves aligning the conductive traces of the cable or circuit with the contacts in the connector, which are then secured in place by a locking mechanism, ensuring a stable electrical connection.
Types of FFC, FPC (Flat Flexible) Connectors
Zero Insertion Force (ZIF) Connectors
ZIF connectors are designed to minimize the force required to insert the cable, reducing the risk of damage during installation. They feature a lever or slider mechanism that opens the connector, allowing the cable to be inserted with minimal effort. Once the cable is in place, the lever is closed, securing the connection. These connectors are ideal for applications requiring frequent disconnection and reconnection.
Low Insertion Force (LIF) Connectors
LIF connectors require slightly more force to insert the cable compared to ZIF connectors but offer a more compact design. They are suitable for applications where space is at a premium, and the connection does not need to be frequently changed. The cable is inserted into the connector, and the contacts are designed to grip the cable securely.
Non-ZIF Connectors
Non-ZIF connectors are the most basic type, requiring the cable to be manually inserted and secured without any additional mechanisms. They are typically used in applications where the connection is permanent or infrequently changed. These connectors are cost-effective and straightforward, making them suitable for less demanding applications.
How to choose FFC, FPC (Flat Flexible) Connectors?
When selecting FFC, FPC connectors, several key parameters should be considered:
Pitch: The distance between the center of one contact to the next. Choose a pitch that matches the cable or circuit.
Number of Contacts: Ensure the connector has the appropriate number of contacts for your application.
Current Rating: Consider the current-carrying capacity required for your application.
Operating Temperature: Ensure the connector can operate within the temperature range of your application.
Locking Mechanism: Choose between ZIF, LIF, or non-ZIF based on your installation and maintenance needs.
To evaluate product quality and reliability, consider suppliers with a proven track record, certifications, and positive customer reviews. Environmental factors such as humidity, vibration, and exposure to chemicals should also be considered, as they can affect connector performance. Installation requirements, such as space constraints and ease of access, should guide the selection process.
