Abstract

Disclosed is a flexible-circuit flat cable with cluster section, including at least one cluster section, at least one slip section, a first connection section, and a second connection section. The first connection section is set at a first end of the cluster section. The slip section has a first end connected to a second end of the cluster section and a second end at which the second connection section is set. The four sections are all provided with a plurality of signal transmission lines corresponding to and connecting each other. The first connection section and the second connection section are selectively provided with a connector or a plugging end. Further, the cluster section includes a cluster structure composed of a plurality of clustered flat cable components that are 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.

Claims

1. 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.

2. The flexible-circuit flat cable as claimed in claim 1, wherein the first end of the slip section forms at least one additional cluster section extending therefrom.

3. The flexible-circuit flat cable as claimed in claim 1, wherein the second end of the slip section forms at least one cluster section extending therefrom.

4. The flexible-circuit flat cable as claimed in claim 1, wherein the first end of the cluster section forms at least one slip section extending therefrom.

5. The flexible-circuit flat cable as claimed in claim 1, wherein the two ends of the cluster section each form at least one additional connection section.

6.
