Method for shielding flat circuit body, shielded flat circuit body, and wiring harness

1. A method for shielding a flat circuit body, which includes a conductor and an insulator to cover said conductor, comprising the steps of:

covering said flat circuit body with a conductive shield film; and

piercing said conductor of the flat circuit body and simultaneously piercing said shield film together with a joint terminal so as to directly electrically connect the conductor of the flat circuit body and said shield film.

2. The method of shielding according to claim 1 , wherein said joint terminal connects the conductors of a plurality of said flat circuit bodies to each other.

3. A method of shielding a flat circuit body, which includes a conductor and an insulator to cover said conductor, comprising the steps of:

covering said flat circuit body with a conductive shield film;

piercing said conductor of the flat circuit body and said shield film together with a joint terminal for connecting them electrically;

piercing a clamp blade of a connector terminal to be mounted at an end of the flat circuit body, which end is not covered with the conductive shield film, through said flat circuit body;

bending said clamp blade so as to connect the conductor of the flat circuit body and the connector terminal electrically with each other;

piercing a joint blade of said joint terminal through both the shield film and the flat circuit body; and

bending said joint blade so as to connect the conductor of the flat circuit body and the shield film electrically with each other,

wherein the clamp blade and the joint blade are pierced through the flat circuit body along a same direction.

4. A shielded flat circuit body comprising:

a flat circuit body having a conductor and an insulator covering said conductor;

a conductive shield film covering the flat circuit body; and

a joint terminal pierced through said conductor of the flat circuit body and simultaneously through said shield film so as to directly connect them electrically.

5. The shielded flat circuit body according to claim 4 , wherein said joint terminal connects the conductors of a plurality of said flat circuit bodies to each other.

6. A wiring harness comprising the shielded flat circuit body as claimed in claim 4 or 5 .

7. The shielded circuit body comprising:

a flat circuit body having a conductor and an insulator covering said conductor;

a conductive shield film covering the flat circuit body;

a joint terminal pierced through said conductor of the flat circuit body and said shield film so as to connect them electrically; and

a connector terminal having a clamp blade to be mounted at an end of the flat circuit body, which end is not covered with the conductive shield film;

wherein said clamp blade of the connector terminal is pierced through said flat circuit body and is bent so as to connect the conductor of the flat circuit body and the connector terminal electrically with each other;

wherein a joint blade of said joint terminal is pierced through both the shield film and the flat circuit body; and

said joint blade is bent so as to connect the conductor of the flat circuit body and the shield film electrically with each other, and

wherein the clamp blade and the joint blade are pierced through the flat circuit body along a same direction.

8. A wiring harness comprising the shielded flat circuit body as claimed in claim 7 .
