Abstract

A flexible wiring member capable of electrically connecting desired points separated in a length direction. The flexible wiring member includes conductor holding layers that are formed in a state of being stacked in a thickness direction and being electrically insulated from one another; power supply line conductors that have a wide width and are respectively disposed in both of a first conductor holding layer and a second conductor holding layer adjacent to each other in the thickness direction; and communication line conductors that have a width smaller than that of the power supply line conductors and are disposed in one of the first conductor holding layer and the second conductor holding layer, in which the conductor holding layers are formed by an insulating resin, and directly cover the power supply line conductors and the communication line conductors.

First claim

What is claimed is:

1. A flexible wiring member capable of electrically connecting a plurality of desired points separated in a length direction, the flexible wiring member comprising:
a plurality of conductor holding layers that are formed in a state of being stacked in a thickness direction and being electrically insulated from one another; and
a power supply ground line conductor that has a wide width and a plurality of communication line conductors that have a width smaller than that of the power supply ground line conductors are disposed in a first conductor holding layer and a power supply line conductor that has a wide width is disposed in a second conductor holding layer, the first conductor holding layer and the second conductor holding layer being adjacent to each other in the thickness direction;
wherein the plurality of conductor holding layers are formed by an insulating resin, and directly cover the power supply line conductor, the power supply ground line conductor, and the communication line conductors,
wherein a width obtained by adding the width of the power supply ground line conductor, the width of the plurality of communication line conductors and the width of portions of the first conductor holding layer disposed therebetween matches the width of the power supply line conductor disposed in the second conductor holding layer, and
wherein, in the first conductor holding layer where the power supply ground line conductor is disposed, the communication line conductors are adjacent to each other.

2. The flexible wiring member according to claim 1 ,
wherein each of the power supply line conductors is a high-voltage power supply line conductor.

3. The flexible wiring member according to claim 1 ,
wherein a width dimension of the power supply ground line conductor disposed in the first conductor holding layer together with the communication line conductors is formed to be smaller than a width dimension of the power supply line conductor disposed in the second conductor holding layer.

4. The flexible wiring member according to claim 1 ,
wherein usage restrictions are made in which a direction of a current flowing through the power supply ground line conductor disposed in the first conductor holding layer together with the communication line conductors and a direction of a current flowing through the power supply line conductor disposed in the second conductor holding layer are set to be opposite to each other.

5. The flexible wiring member according to claim 1 ,
wherein the power supply line conductor, the power supply ground line conductor and the communication line conductors are made of conductive metals having a foil shape and having the same thickness.
