Abstract

A fitting-equipped conductive sheet including: a conductive sheet material in which a plurality of conductive strands are aligned planarly; and a plate-shaped conductive fitting attached to ends of the plurality of conductive strands, wherein the conductive fitting includes a folded-back portion, and a first sandwiching portion and a second sandwiching portion that are folded back with the folded-back portion as a starting point and the first sandwiching portion and the second sandwiching portion are opposed to each other.

First claim

The invention claimed is:

1. A fitting-equipped conductive sheet comprising:
a conductive sheet material in which a plurality of conductive strands are aligned planarly; and
a plate-shaped conductive fitting attached to ends of the plurality of conductive strands,
wherein the conductive fitting includes a folded-back portion, and a first sandwiching portion and a second sandwiching portion that are folded back with the folded-back portion as a starting point and the first sandwiching portion and the second sandwiching portion are opposed to each other,
a bent apex resulting from the first sandwiching portion having been bent toward the second sandwiching portion is formed on an inner surface of the first sandwiching portion so as to be parallel to a parting line of the folded-back portion,
the ends of the plurality of conductive strands are electrically connected to the conductive fitting by being brought into pressure contact with the bent apex and sandwiched between the bent apex and the second sandwiching portion so as to intersect the bent apex, and
a projection having a smaller radius of curvature than the bent apex is formed on an inner surface of the first sandwiching portion or the second sandwiching portion at a position located on the conductive sheet material side relative to the bent apex so as to be in contact with the ends of the plurality of the conductive strands.

2. The fitting-equipped conductive sheet according to claim 1 ,
wherein the plurality of conductive strands are aligned along a direction perpendicular to a direction in which the bent apex is formed, and
portions of the plurality of conductive strands that are other than the ends are maintained in a state in which a predetermined interval is maintained therebetween by an insulating reinforcing material.

3. The fitting-equipped conductive sheet according to claim 2 ,
wherein the reinforcing material includes linear portions that intersect the plurality of conductive strands, and
the plurality of conductive strands are braided by the linear portions.

4. The fitting-equipped conductive sheet according to claim 1 ,
wherein the projection is formed by a part of a material of the conductive fitting that protrudes from the inner surface along a direction in which the bent apex is formed.

5. The fitting-equipped conductive sheet according to claim 1 ,
wherein the projection is a formed by an addition material integrated in one piece with the inner surface along a direction in which the bent apex is formed.

6. The fitting-equipped conductive sheet according to claim 1 ,
wherein the projection is formed on the inner surface of the second sandwiching portion.

7. The fitting-equipped conductive sheet according to claim 1 ,
wherein the conductive fitting is attached to opposite ends of the plurality of conductive strands, and includes an attachment for externally attaching the conductive fitting, and
the fitting-equipped conductive sheet is used as an electromagnetic shielding material that covers an electromagnetic noise source with the conductive sheet material.
