[0070] Plug connectors are commonly used electronic components, usually used between blocked or isolated circuits, acting as a bridge of communication, so that the circuit is conductive and the predetermined function of the circuit is realized. At the same time, it is also a bridge for signal transmission and reception. A flexible circuit board connector is a type of commonly used plug-in connector, usually used to connect flexible circuit board cables, such as FPC (Flexible Printed Circuit) cables. Existing flexible circuit board connectors usually achieve connection and conduction between different circuits through signal terminals. The signal terminals are usually installed in the housing and connected to the flip cover at the same time, and the flexible circuit board is fixedly inserted by the flip cover. Therefore, the existing signal terminals often also need to take into account the function of fixed connection to the housing, that is, the existing signal terminals include an integrally arranged signal terminal and a hook, which results in the hook sharing some signals when in use. When performing SI (Signal Integrity) testing, the signal loss is serious, which ultimately leads to poor SI performance of the flexible circuit board connector. At the same time, as the market demand gradually tends towards ultra-thinness, the thickness of the flexible circuit board connector can only become thinner and thinner, which requires the thickness of the entire component of the flexible circuit board connector to become thinner and thinner; among them, the current flip covers of the flexible circuit board connector are all injection-molded with insulating plastic, resulting in weak strength of the flip cover body, which makes the ultra-thin flip cover more prone to deformation, detachment and breakage, causing the connector to be unable to be used normally.

[0071] The present invention is based on the problems of poor SI performance and insufficient cover strength of flexible circuit board connectors in the prior art, and provides a flexible circuit board connector. By setting a hook terminal and a signal terminal, the signal terminal in the flexible circuit board connector is only used to transmit signals, thereby effectively avoiding signal loss in the signal terminal during signal transmission, and improving the SI performance of the flexible circuit board connector; at the same time, by setting a reinforcement structure on the flip cover, the strength of the flip cover body is effectively enhanced, and the reinforcement structure is plastic-sealed on the flip cover by using embedded injection molding technology, ultimately achieving the goal of ensuring the strength of the flip cover while providing a guarantee for reducing the thickness of the flip cover.
