Connector

1. A connector having a flat cable connecting portion connected to a flat cable and a flat mating portion mated with another connector, the connector comprising:

a plurality of terminals arranged on the mating portion for establishing contact with terminals on the other connector;

a conductive connecting portion exposed on the cable connecting portion and connected to conductive trace connecting portions on the flat cable, and

a plurality of wiring lines extending from the mating portion to the cable connecting portion, each one electrically connecting a terminal to the corresponding conductive trace connecting portion;

wherein the conductive connecting portion having a protrusion formed on the wiring lines, and the upper surface of the protrusion being substantially the same height as one outer surface of the cable connecting portion.

2. The connector of claim 1 , wherein the cable connecting portion has connecting portion accommodating openings passing through the cable connecting portion in the thickness direction, and each conductive connecting portion is exposed inside each connecting portion accommodating opening.

3. The connector of claim 2 , wherein each connecting portion accommodating opening is wider than the conductive connecting portion.

4. The connector of claim 3 , wherein the cable connecting portion includes insulating base film arranged on one surface of the wiring lines and an insulating cover film arranged on the other surface of the wiring lines.

5. The connector of claim 4 , wherein each connecting portion accommodating opening includes an opening passing through the insulating base film in the thickness direction and an opening passing through the insulating cover film in the thickness direction.

6. The connector of claim 5 , wherein the upper surface of each protrusion is substantially the same height as the outer surface of the base film.

7. The connector of claim 6 , wherein the conductive connecting portions are arranged side by side so as to form a plurality of rows extending in the width direction of the connector.

8. The connector of claim 7 , wherein conductive connecting portions in adjacent rows are arranged so as to be staggered at half a pitch relative to each other in the thickness direction of the connector.

9. The connector of claim 1 , wherein the conductive connecting portions are arranged side by side so as to form a plurality of rows extending in the width direction of the connector.

10. The connector of claim 9 , wherein conductive connecting portions in adjacent rows are arranged so as to be staggered at half a pitch relative to each other in the thickness direction of the connector.

11. The connector of claim 2 , wherein the conductive connecting portions are arranged side by side so as to form a plurality of rows extending in the width direction of the connector.

12. The connector of claim 11 , wherein conductive connecting portions in adjacent rows are arranged so as to be staggered at half a pitch relative to each other in the thickness direction of the connector.

13. The connector of claim 3 , wherein the conductive connecting portions are arranged side by side so as to form a plurality of rows extending in the width direction of the connector.

14. The connector of claim 13 , wherein conductive connecting portions in adjacent rows are arranged so as to be staggered at half a pitch relative to each other in the thickness direction of the connector.
