Multilayered flexible flat cable and manufacturing method thereof

A manufacturing method of a multilayered flexible flat cable, comprising:

• arranging a plurality of first wires and a plurality of second wires between two insulating films, wherein the plurality of first wires and the plurality of second wires keep a distance;
• punching in at least one of the two insulating films so as to form a plurality of connecting end holes and a plurality of crimping end holes, wherein the plurality of connecting end holes and the plurality of crimping end holes extend from the at least one of the two insulating films to the plurality of first wires or the plurality of second wires;
• punching in the plurality of first wires and the plurality of second wires so as to form a plurality of cut-off holes, wherein the plurality of cut-off holes respectively extend through the plurality of first wires and the plurality of second wires;
• making a plurality of crimping terminals be respectively crimped to the plurality of first wires or the plurality of second wires through the plurality of crimping end holes;
• folding the two insulating films to make the plurality of first wires and the plurality of second wires be overlapped;
• making a plurality of detecting elements be respectively connected to the plurality of first wires or the plurality of second wires through the plurality of connecting end holes;
• and
• sticking the two insulating films to make the two insulating films be fixed to a folding state and form the multilayered flexible flat cable.

A manufacturing method of a multilayered flexible flat cable, comprising:

• arranging a plurality of first wires between two first insulating films so as to form a first wire unit;
• arranging a plurality of second wires between two second insulating films so as to form a second wire unit;
• punching in one of the two first insulating films and one of the two second insulating films so as to form a plurality of connecting end holes and a plurality of crimping end holes, wherein the plurality of connecting end holes and the plurality of crimping end holes extend from the one of the two first insulating films to the plurality of first wires, or extend from the one of the two second insulating films to the plurality of second wires;
• punching in the plurality of first wires and the plurality of second wires so as to form a plurality of cut-off holes, wherein the plurality of cut-off holes respectively extend through the plurality of first wires and the plurality of second wires;
• making a plurality of crimping terminals be respectively crimped to the plurality of first wires or the plurality of second wires through the plurality of crimping end holes;
• making a plurality of detecting elements be respectively connected to the plurality of first wires or the plurality of second wires through the plurality of connecting end holes;
• and
• sticking the first wire unit and the second wire unit to make the plurality of first wires and the plurality of second wires be overlapped and form the multilayered flexible flat cable.
