Patent ID: 7470862

Claim:
A signal transmission cable, comprising: a flexible circuit substrate provided with a plurality of signal transmission lines; a first connection section formed at a first end of the flexible circuit substrate and having a plurality of signal transmission lines, the first connection section being provided on a lower surface at two lateral sides with an adhering layer each; a first connector provided on the first connection section, areas at two lateral sides of the first connector being downward folded to overlap each other below the first connector and being fixed in place via the two adhering layers of the first connection section; a second connection section formed at a second end of the flexible circuit substrate and having a plurality of signal transmission lines, the second connection section being provided on a lower surface at two lateral sides with an adhering layer each; a second connector provided on the second connection section, the areas at two lateral sides of the second connector being downward folded to overlap each other below the second connector and being fixed in place via the two adhering layers of the second connection section; and a cluster section formed at a middle section of the flexible circuit substrate between the first and the second connection section, and having a plurality of signal transmission lines connected at two ends to the signal transmission lines on the first and the second connection section respectively; the cluster section including a plurality of clustered flat cables, which are formed by cutting the flexible circuit substrate along a plurality of paralleled cutting lines extended in the lengthwise direction of the flexible circuit substrate; the clustered flat cables being independently and freely bendable, and each of the clustered flat cables including at least one signal transmission line therein; and areas on the first and the second connection section at two lateral sides of the first and the second connector being downward foldable to overlap each other below the first and the second connector, respectively.
