Patent ID: 8283575

Claim:
A flexible-circuit flat cable comprising: at least one cluster section, which comprises a first end and a second end between which a plurality of signal transmission lines are arranged; at least one slip section, which comprises a first end and a second end, the first end of the slip section being connected to the second end of the cluster section, a plurality of signal transmission lines being arranged between the first and second ends of the slip section and respectively connecting to the signal transmission line of the cluster section; a first connection section, which is set at the first end of the cluster section, the first connection section comprising a plurality of signal transmission lines respectively connecting to the signal transmission lines of the cluster section; and a second connection section, which is set at the second end of the cluster section, the second connection section comprising a plurality of signal transmission lines respectively connecting to the signal transmission lines of the cluster section; wherein the cluster section comprises a cluster structure composed of a plurality of clustered flat cable components that is formed by slitting in a direction parallel to extension direction of a flexible circuit board to impose free and independent flexibility for bending to each clustered flat cable component, each clustered flat cable component comprising at least one of the signal transmission lines; at least one bundling structure is formed on a lateral side edge of a predetermined clustered flat cable component of the cluster section and the bundling structure forms a fastening section, whereby when the clustered flat cable components of the cluster section of the flexible circuit board are stacked to form a bundled structure, the bundling structure bundles the plurality of clustered flat cable components and is secured by being fastened by the fastening section; and the fastening section of the bundling structure comprises an adhesive layer, which adhesively secures the clustered flat cable components when the bundling structure bundles the plurality of the clustered flat cable components.
