Abstract

A branch structure of a laminated flat electric wire includes: a laminated flat electric wire in which two or more plate-shaped flat electric wires are laminated; and a branch box. The laminated flat electric wire has tabs each extending from each of the flat electric wires. Each of the tabs is provided with a hole. The branch box has the same number of rod-shaped members as the number of tabs, and the rod-shaped members are disposed at positions corresponding to the positions of the holes of the tabs. Two or more laminated flat electric wires are fixed to each other by passing each of the rod-shaped members through a corresponding hole of the tabs in a state where the two or more laminated flat electric wires extend from the branch box in opposite directions from each other or directions orthogonal to each other.

First claim

What is claimed is:

1. A laminated flat electric wire comprising:
two or more plate-shaped flat electric wires which are laminated; and
a tab extending from each of the plate-shaped flat electric wires, each of the tabs being provided with a hole, the tabs being provided so as not to overlap each other in a plan view as viewed in a direction along a lamination direction of the laminated flat electric wire,
wherein the positions of the ends of the tabs in a direction in which the tabs extend are different from each other, and
wherein the holes of the tabs are disposed at predetermined intervals on a straight line having an inclination of 45° with respect to the extending direction of the laminated flat electric wire in the plan view as viewed in the direction along the lamination direction of the laminated flat electric wire.

2. The laminated flat electric wire according to claim 1 , wherein:
the holes of the tabs are disposed at positions different from each other in a direction orthogonal to the extending direction of the laminated flat electric wire.

3. The laminated flat electric wire according to claim 1 , wherein:
the tabs are arranged in order of a length in a width direction of the laminated flat electric wire in the plan view as viewed in the direction along the lamination direction of the laminated flat electric wire;
the hole of each tab is provided in a vicinity of a tip portion of the respective tab.

4. A branch structure comprising:
a laminated flat electric wire comprising:
two or more plate-shaped flat electric wires which are laminated;
a tab extending from each of the plate-shaped flat electric wires, each of the tabs being provided with a hole, the tabs being provided so as not to overlap each other in a plan view as viewed in a direction along a lamination direction of the laminated flat electric wire; and
a branch box having the same number of rod-shaped members as the number of tabs on the laminated flat electric wire, the rod-shaped members being disposed at positions corresponding to the positions of the holes of the tabs,
wherein the positions of the ends of the tabs in a direction in which the tabs extend are different from each other.

5. The branch structure according to claim 4 , wherein the branch structure is configured such that the tabs, through which the same rod-shaped member passes, are electrically connected to each other by fixing two or more laminated flat electric wires to each other by passing each of the rod-shaped members through a corresponding hole of the tabs in a state where the two or more laminated flat electric wires extend from the branch box in opposite directions from each other or directions orthogonal to each other.

6. The branch structure according to claim 5 , wherein:
the holes of the tabs are disposed at positions different from each other in a direction orthogonal to the extending direction of the laminated flat electric wire.

7. The branch structure according to claim 4 , wherein:
the holes of the tabs are disposed at predetermined intervals on a straight line having an inclination of 45° with respect to the extending direction of the laminated flat electric wire in the plan view as viewed in the direction along the lamination direction of the laminated flat electric wire.

8. The branch structure according to claim 7 , wherein:
four or less laminated flat electric wires are fixed to the branch box.
