Electric interconnect structure for fuel cell vehicles
A fuel cell vehicle has both left-hand drive specifications and right-hand drive specifications. A first converter is placed at a same position whichever of the left-hand drive specifications or the right-hand drive specifications are applied. A second converter is placed on a selected one of the left-hand side and the right-hand side of the center line of the fuel cell vehicle for the left-hand drive specifications, while, for the right-hand drive specifications, placed on the other side of the center line of the fuel cell vehicle opposite to the selected one side for the left-hand drive specifications. A first wire harness to be used as the wire harness for the left-hand drive specifications and a second wire harness to be used as the wire harness for the right-hand drive specifications are equal in length to each other.

the M1 pieces of clamps include a first clamp which the first wire harness connected to the connector of the first converter first reaches among the M1 pieces of clamps,
the first wire harness is laid down to pass along a rightward route through N1 pieces of clamps including the first clamp up to an N1-th clamp successively out of the M1 pieces of clamps where N1 is an integer within a range of 2 to (M1−1), thereafter passing through one or more pieces of clamps provided on the right-hand side of the N1-th clamp out of the M1 pieces of clamps so as to be fixed by those respective clamps, and going on toward the second converter,
the second wire harness is fixed to the dash panel part of the fuel cell vehicle using at least part of M2 pieces of clamps set on the dash panel part for fixation of the second wire harness, where M2 is an integer of at least. 3, wherein
the M2 pieces of clamps include a first clamp which the second wire harness connected to the connector of the first converter first reaches among the M2 pieces of clamps,
the second wire harness is laid down to pass along a rightward route through N2 pieces of clamps including the first clamp up to an N2-th clamp successively where N2 is an integer within a range of 2 to (M2−1), and thereafter is reversed so as to form a bent portion, then passing through one or more pieces of clamps provided on the left-hand side of the first clamp out of the M2 pieces of clamps so as to be fixed by those respective clamps, and going on toward the second converter, and
the N2-th clamp is provided at a position immediately preceding the bent portion of the second wire harness.
