  • Patent number: 8242374
    Abstract: Provided is a flexible-circuit-board cable having a positioning structure. A connection zone is defined in a free end of the flexible-circuit-board cable and is provided with a plurality of conductive contacts. The connection zone has a first surface on which at least one projection section is formed and a second surface. A shielding layer overlaps the projection section and a portion of the first surface.
