Technical Field

[0001] This utility model relates to the field of electrical connections, and in particular to a flexible printed circuit board electrical connector. Background Technology

[0002] Flexible printed circuit boards (FPCs) are commonly used components in digital products such as mobile phones and computers. They are characterized by good flexibility, light weight, and thinness. A similar component is the flexible flat cable (FFC), and both have similar application scenarios and functions. However, in practical applications, both FPCs and FFCs require electrical connectors to achieve electrical connections with other components. For ease of description, FPCs and FFCs are collectively referred to as flexible boards. Existing electrical connectors suffer from issues such as inaccurate guidance during insertion and removal, inconvenient insertion and removal, difficulties in grounding the PCB board, insufficient security after insertion, and problems with insufficient locking force and easy loosening.
