Abstract

Manufacturing is carried out while including the steps of: from a trunk line 12, drawing out electric wires 13a to be a branch line 14 longer than a required length of the branch line 14; forming a branch line portion 17 by applying tape winding to the drawn-out electric wires 13a; making, as a trunk line accompanying part 17a, a part from a base end P2 to a branching position P1 of the branch line portion 17 accompany the trunk line 12 and making, as a main branch line part 17b, a part from the branching position P1 to a front end P3 of the branch line portion 17 distant from the branch line 12; and applying an protecting treatment 19 by tape winding to the whole.

Claims

1. A method for manufacturing a wire harness branching portion comprising the steps of:

drawing out, from a trunk line of a wire harness, electric wires to be a branch line longer than a required length of the branch line;

forming a branch line portion by applying tape winding to the drawn-out electric wires;

accompanying a trunk line accompanying part defined from a proximal end of the branch line to a branching position of the branch line portion with the trunk line;

keeping away a main branch line part, defined from the branching position of the branch line portion to a distal end of the branch line portion, from the trunk line; and

applying an protecting treatment by tape winding to the whole.

2. A method for manufacturing a wire harness branching portion comprising the steps of:

separating a first trunk line including protecting target electric wires from a second trunk line without protecting target electric wires;

drawing out, from the first trunk line, electric wires to be a protecting target branch line longer than a required length of the branch line;

forming a protecting target branch line portion by winding tape to the drawn-out electric wires;

accompanying a trunk line accompanying part, defined from a proximal end of the protecting target branch line portion to a branching position of the protecting target branch line portion, with the first trunk line;

keeping away a main branch line part, defined from the branching position of the protecting target branch line portion to a distal end of the protecting target branch line portion, from the first branch line;

drawing out, from the second trunk line, a general branch line portion defined by an electric wires to be a general branch line with a required length of the branch line;

keeping away the general branch line portion distant from the second trunk line;

overlapping the first trunk line and second trunk line with aligning the main branch line part and the general branch line portion in position; and

applying an protecting treatment by winding tape to the whole.

3. A method for manufacturing a wire harness branching portion comprising the steps of:

separating drawing out, from at least two trunk lines including protecting target electric wires, electric wires to be protecting target branch lines longer than a required length of the branch lines;

forming protecting target branch line portions by respectively winding tape to the drawn-out electric wires;

accompanying trunk line accompanying parts defined from each proximal end to each branching position of the protecting target branch line portions with the trunk lines, respectively;

keeping away main branch line parts, defined from each branching position to each distal end of the protecting target branch line portions distant, from the trunk lines, respectively;

overlapping the trunk lines with each other with aligning the main branch line parts in position with each other; and

applying a protecting treatment by winding tape to the whole.
