Abstract

The invention discloses an improved structure of a flexible circuit board connector, which includes a main body seat, a plurality of first terminals, a plurality of second terminals, a movable cover and other components. The main feature of the invention is that when the flexible circuit board is to be inserted, the movable cover can be pivoted and opened outward by pivoting arc blocks on both sides thereof, and the flexible circuit board can be inserted immediately. Then, the movable cover is pivoted and returned to its original position, and the support arm of the first terminal can be moved upward by the hook portion of the linkage plate, and the contact convex card of the contact arm can be moved to electrically contact the flexible circuit board. When the movable cover is returned to its original position, the flexible circuit board can be pressed to electrically contact the contact convex card of the contact arm of the second terminal. In addition, the first terminal is not only embedded in the embedding groove of the main body seat by its support arm and contact arm, but also blocked by the upper end edge wall surface of the embedding groove of the main body seat by the blocking portion of its fixed arm, and at the same time, its horizontal embedding piece is embedded in the fixed groove of the main body seat, so it has a stable positioning effect.
