Description

Technical Field

[0001] The utility model relates to an FPC connector, belonging to the field of electrical components. Background Art

[0002] Flexible circuit boards are printed circuit boards made of flexible insulating substrates (mainly polyimide or polyester film), and have many advantages that rigid printed circuit boards do not have. For example, they can be bent, wound, and folded freely. The use of FPC can greatly reduce the size of electronic products, and meet the needs of electronic products to develop in the direction of high density, miniaturization, and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptops, computer peripherals, PDAs, digital cameras, and other fields or products. The interface component used to connect flexible circuit boards is the flexible circuit board connector, commonly known as the FPC connector. The FPC connector includes a rubber core, a flap, a terminal piece, and a solder piece. The structural design of the existing FPC connector is unreasonable, and the flap is easy to loosen, making the contact between the terminal piece and the cable unreliable, and there is a phenomenon of poor contact, which reduces the service life of the FPC connector and deteriorates the use effect.
