Flat cable with improved short-circuit prevention function

A flat cable extending straight in a lengthwise direction until a front edge, the flat cable comprising:

• a plurality of conductors made of an electrical conductive material, and extending straight along the lengthwise direction of the flat cable to the front edge of the flat cable, wherein the plurality of conductors are spaced apart a predetermined distance in a widthwise direction of the flat cable;
• a cable body made of an insulating material, and extending straight along the lengthwise direction of the flat cable, wherein the conductors are mounted on an upper surface of the cable body, wherein a cable insert portion of the cable body is configured to be inserted and connected to an external connector, wherein the cable insert portion of the cable body extends in the lengthwise direction until the front edge of the flat cable, and wherein the cable insert portion includes a protruding portion protruding out in the lengthwise direction of the flat cable beyond the plurality of conductors;
• and
• a reinforcing portion positioned on the upper surface of the cable body, including at least part of the protruding portion, and configured to reinforce stiffness of the protruding portion, wherein the reinforcing portion extends in the lengthwise direction of the flat cable beyond the plurality of conductors,
• wherein the reinforcing portion is positioned over a surface of the plurality of conductors such that the plurality of conductors are positioned between the cable body and the reinforcing portion.
