Underfloor shielded harness
An underfloor shielded harness ( 100 ) has a long conductive plate which is wound so as to have at least two internal spaces ( 104, 105 ) in a cross section taken perpendicularly to the longitudinal direction. High-voltage cables ( 102 ) is inserted in the internal space ( 104 ) of the conductive plate ( 103 ) and the low-voltage cable ( 101 ) is inserted in the internal space ( 105 ) that is different from the internal space ( 104 ) in which the high-voltage cables ( 102 ) is inserted. At least one of the two internal spaces ( 104, 105 ) communicates with the outside of the spaces ( 104, 105 ) formed by the conductive plate ( 103 ).
1. An underfloor shielded harness which is to be routed across a vehicle body underfloor surface which is an outside surface of a vehicle body frame and has a low-voltage cable that includes one or plural wires and a high-voltage cable that includes one or plural wires and to which a higher voltage higher than a voltage to be applied to the low-voltage cable is to be applied, wherein:
the underfloor shielded harness comprises a long conductive plate which is wound so as to have at least two internal spaces in a cross section taken perpendicularly to a longitudinal direction;
in the long conductive plate, the high-voltage cable is inserted in one of the at least two internal spaces of the conductive plate and the low-voltage cable is inserted in an internal space other than the one, in which the high-voltage cable is inserted, of the at least two internal spaces; and
at least one of the at least two internal spaces communicates with an outside of the spaces formed by the conductive plate.
2. The underfloor shielded harness according to claim 1 , wherein:
the conductive plate is wound so as to assume an approximately spiral shape in a cross section taken perpendicularly to the longitudinal direction and thereby has the at least two internal spaces; and
an outermost internal space, of the spiral, of the at least two internal spaces communicates with the outside of the spaces formed by the conductive plate.
3. The underfloor shielded harness according to claim 2 , wherein the internal space in which the high-voltage cable is inserted exists, in the spiral, on a side that is located inside a side where the internal space in which the low-voltage cable is inserted exists.
4. The underfloor shielded harness according to claim 3 , wherein the internal space in which the high-voltage cable is inserted is an innermost space of the spiral and an end of the conductive plate is in contact with a wall of the conductive plate.
5. The underfloor shielded harness according to claim 3 , wherein the internal space in which the high-voltage cable is inserted is an innermost space of the spiral and an end of the conductive plate is not in contact with a wall of the conductive plate.
