Abstract

A sheet type conductive member includes a tongue portion projecting in a tongue shape in a predetermined plane, a contact arrangement region in which a contact of a connector is arranged being laid out on a front surface of the sheet type conductive member, a first flexible conductor being exposed on the contact arrangement region, a second flexible conductor being exposed on a rear surface of the tongue portion, at least part of the tongue portion being folded back to a front surface side of the sheet type conductive member so that a contact connecting portion composed of part of the first flexible conductor and part of the second flexible conductor is formed in the contact arrangement region.

First claim

What is claimed is:

1 . A sheet type conductive member that extends along a predetermined plane and is attached to a connector, the sheet type conductive member comprising:
a sheet body having insulating properties; and a first flexible conductor disposed on a front surface side of the sheet body, and a second flexible conductor disposed on a rear surface side of the sheet body, wherein the sheet type conductive member comprises a tongue portion projecting in a tongue shape in the predetermined plane, wherein a contact arrangement region in which a contact of the connector is arranged is laid out on a front surface of the sheet type conductive member, wherein the first flexible conductor is exposed on the contact arrangement region, wherein the second flexible conductor is exposed on a rear surface of the tongue portion, and wherein at least part of the tongue portion is folded back to a front surface side of the sheet type conductive member so that a contact connecting portion composed of part of the first flexible conductor and part of the second flexible conductor is formed in the contact arrangement region.

2 . The sheet type conductive member according to claim 1 , wherein on an outside of the contact arrangement region, the tongue portion extends in a direction away from the contact arrangement region.

3 . The sheet type conductive member according to claim 1 , further comprising a third flexible conductor disposed between the first flexible conductor and the second flexible conductor and electrically insulated from the first flexible conductor and the second flexible conductor.

4 . The sheet type conductive member according to claim 1 , further comprising an opening portion formed in the contact arrangement region,
wherein the tongue portion extends from a periphery of the contact arrangement region toward an inside of the opening portion.

5 . The sheet type conductive member according to claim 4 ,
wherein the sheet type conductive member comprises, in the contact arrangement region, at least one protruding portion projecting in the predetermined plane from the periphery of the contact arrangement region toward the inside of the opening portion, and wherein the first flexible conductor is exposed on a front surface of the at least one protruding portion.

6 . The sheet type conductive member according to claim 1 , further comprising an insertion hole penetrating from the front surface to a rear surface of the sheet type conductive member,
wherein the tongue portion is provided at its tip with an insertion portion formed to be wider than the insertion hole, and wherein the insertion portion of the tongue portion folded back to the front surface side of the sheet type conductive member is inserted into the insertion hole, whereby the tongue portion folded back is retained.

7 . The sheet type conductive member according to claim 6 , wherein the insertion hole is formed in the contact arrangement region.

8 . The sheet type conductive member according to claim 6 , wherein the insertion hole is formed outside the contact arrangement region.

9 . A connector configured to be fitted with a counter connector in a fitting direction, comprising:
a sheet type conductive member that extends along a predetermined plane; a contact; and a housing having insulating properties and configured to retain the sheet type conductive member and the contact, wherein the sheet type conductive member comprises:
a sheet body having insulating properties; and
a first flexible conductor disposed on a front surface side of the sheet body, and a second flexible conductor disposed on a rear surface side of the sheet body,
wherein the sheet type conductive member comprises a tongue portion projecting in a tongue shape in the predetermined plane, wherein a contact arrangement region in which a contact of the connector is arranged is laid out on a front surface of the sheet type conductive member, wherein the first flexible conductor is exposed on the contact arrangement region, wherein the second flexible conductor is exposed on a rear surface of the tongue portion, wherein at least part of the tongue portion is folded back to a front surface side of the sheet type conductive member so that a contact connecting portion composed of part of the first flexible conductor and part of the second flexible conductor is formed in the contact arrangement region, wherein the contact is connected to the contact connecting portion in the contact arrangement region.

10 . The connector according to claim 9 ,
wherein the contact comprises a projection accommodating portion of recess shape, wherein the housing has a projection inserted into the projection accommodating portion of the contact, and wherein when the projection is, together with the sheet type conductive member, inserted into the projection accommodating portion of the contact, the first flexible conductor and the second flexible conductor that are disposed in the contact arrangement region are sandwiched between a lateral surface of the projection and an inner surface of the projection accommodating portion in a direction orthogonal to the fitting direction so as to contact the inner surface of the projection accommodating portion, whereby the contact is electrically connected to the first flexible conductor and the second flexible conductor.

11 . The connector according to claim 10 , wherein the contact has a tubular portion in which the projection accommodating portion is formed, and a flange that is formed at one end of the tubular portion,
wherein the housing comprises a top insulator provided with a contact through-hole that is penetrated by the tubular portion of the contact and is smaller than the flange, and a bottom insulator provided with the projection, and wherein the top insulator is fixed to the bottom insulator such that the tubular portion of the contact penetrates the contact through-hole and the sheet type conductive member and the flange are sandwiched between the top insulator and the bottom insulator, whereby the sheet type conductive member and the contact are retained in the housing.
