The plug-in methods of FPC connectors mainly include standard pin connection and flexible board socket connection.
The standard needle connection is commonly used for small instruments, where two soft weights are connected through standard pins, usually parallel or perpendicular, making it easy to achieve mass production. The connection of the soft board socket is to make printed plugs from the edge of the soft board, and the plug part is designed according to the size, number of contacts, contact distance, positioning hole position, etc. of the socket to match the dedicated soft board socket. This method is easy to assemble, has good interchangeability and maintenance performance, and is suitable for standardized mass production.
During the plugging process, the following points should be noted:
Convenient use of reinforcement board: The reinforcement board not only strengthens the thickness of the plug end, but also plays a role in adjusting the thickness to ensure compatibility with the FPC connector. The marking lines on the reinforcement board are crucial for ensuring the correct insertion of FFC cables, which can help operators determine the depth and direction of insertion, and avoid inserting the cables incorrectly or excessively.
Insertion method: Depending on the type of EPC connector, FFC ribbon cables can be inserted horizontally or vertically. In special and narrow spaces, one or both hands can be used to hold the ribbon cable for insertion.
Maintain flatness: When inserting the FPC connector, ensure the flatness of the FFC cable to avoid arcs or twists. It should be ensured that the reinforcing plate is parallel to the slot surface of the connector to avoid damage to the end conductor of the cable. In addition, common plug-in methods include direct insertion connection, ZIF connection (Zero insertion force), and LIF connection (Low insertion force). Direct insertion connection is simple and convenient, suitable for situations that require frequent replacement of FFC. The ZIF connector adopts a movable locking sub cover to ensure the concealment of the connection, which is suitable for frequent plugging and unplugging of the connector. The LIF connector needs to be unlocked before inserting the FFC, which is also suitable for frequent plugging and unplugging of the connector.
