Abstract

An improved structure of a flexible circuit board connector comprises a body base, a plurality of terminals, a movable cover, two gaskets, etc. The flexible circuit board connector is characterized in that the upper wall surface of the body base is shorter than the lower wall surface and the two sides of the body base form concave parts. The pivot shaft of the coupled plate of the movable cover is arranged at the lateral end of an arc shaped block, therefore the movable block can stably pivot not only in two pivot grooves at the two sides of the body base by the pivot shaft but also in the intervate parts of the body base by two arc-shaped blocks; moreover, after the pivot of the movable cover is turned on, the movable cover can resist the front end of the shorter upper wall surface of the body base by the upper end surface of the coupled plate of the movable cover to have a larger opening angle with 90 DEG, thus being relatively convenient for the insertion of a flexible circuit board. Moreover, the two lateral ends of the front side of the movable cover are provided with slots to avoid interfering the front side of the two lateral walls of the body base, and in the process of manufacturing, the two lateral walls of the body base can extend forwards as long as possible to be only a little shorter than the length of the lower wall surface, thereby increasing the strength of the two lateral walls of the body base.
