Wiring material, method for fabricating the same, and secondary battery device and electronic equipment using the same
A wiring material includes conductors, each of which has a cross section having a thickness and a width not less than the thickness, a trunk portion in which the conductors are spaced parallel in a direction of the width thereof, a branch portion in which each conductor is bent and branched from the trunk portion in the direction of the width or in a direction that intersects the direction of the width, and a covering member for covering the trunk portion and the branch portion to expose both ends of the conductors.
1. A wiring material comprising:
conductors, each conductor comprising a conductor trunk portion extending in a longitudinal direction of the wiring material and a conductor branch portion directly branched from without overlapping the conductor trunk portion in a direction intersecting the width direction; and
a covering member collectively covering around the conductor trunk portion and the conductor branch portion to expose both ends of the conductors, the conductor trunk portion being arranged in parallel in the width direction in the covering member,
wherein the covering member comprises a trunk covering portion for covering the conductor trunk portions and branch covering portions each of which covers the conductor branch portion.
2. The wiring material according to claim 1 , wherein each conductor has a rectangular cross section.
3. The wiring material according to claim 1 , wherein the covering member comprises: a first covering member for covering the trunk portion to expose an end of each conductor on a side of the trunk portion; and a second covering member for covering the branch portion to expose an end of the conductor on a side of the branch portion.
4. The wiring material according to claim 3 , wherein the second covering member is partially overlapped with the first covering member to cover a portion of the trunk portion covered with the first covering member.
5. A secondary battery device comprising the wiring material according to claim 1 .
6. An electronic equipment comprising the wiring material according to claim 1 .
7. The wiring material according to claim 1 , wherein each conductor has a cross section comprising a predetermined thickness and a width not less than the predetermined thickness.
8. The wiring material according to claim 1 , wherein the wiring material has a same thickness in the longitudinal direction.
9. The wiring material according to claim 8 , wherein the branch portion of each conductor is coplanar with the trunk portion where it directly branches from.
10. A wiring material comprising:
conductors, each conductor comprising a conductor trunk portion extending in a longitudinal direction of the wiring material and a conductor branch portion directly branched from without overlapping the conductor trunk portion in a direction intersecting the width direction; and
a covering member collectively covering around the conductor trunk portion and the conductor branch portion to expose both ends of the conductors, the conductor trunk portion being arranged in parallel in the width direction in the covering member,
wherein the covering member comprises: a first covering member for covering the trunk portion to expose an end of each conductor on a side of the trunk portion; and a second covering member for covering the branch portion to expose an end of the conductor on a side of the branch portion, and
wherein the second covering member is partially overlapped with the first covering member to cover a portion of the trunk portion covered with the first covering member.
