Its working principle is based on the synergistic effect of electrical contact and mechanical locking:
Electrical connection: When an FPC with gold fingers is inserted into the connector docking cavity, the contact terminals of the connector are in close contact with the conductive lines (gold fingers) on the FPC, forming a conductive path to achieve signal or power transmission.
Mechanical locking and fixation: After insertion, the locking mechanism (such as flip down, sliding cover locking, or ZIF pressure strip fastening) will generate uniform mechanical pressure, firmly pressing the FPC between the terminals to prevent poor contact or detachment caused by vibration or pulling. For zero insertion force (ZIF) connectors, it is necessary to first open the locking cover and then insert the FPC, and then tighten and fix it.
In addition, FPC connectors are widely used in scenarios that require lightweight and flexible connectivity, such as smartphones, wearable devices, and automotive electronics, due to their ultra-thin design (up to 0.6mm), high flexibility (supporting dynamic bending), high-density connections (with a minimum spacing of 0.3mm), and high reliability (with a plug and unplug life of thousands to tens of thousands of times).
