Each of the plurality of electric wires of the electric wire bundle 50 is a covered electric wire having a conductor and an insulating coating that covers the conductor. Further, the conductors of several thick wires through which a large current flows in the wire bundle 50 are made of an aluminum alloy. Moreover, the conductor of several thin electric wires which perform signal transmission among the electric wire bundles 50 is comprised with the copper alloy.

“ Electric wire bundle 50” may be an electric wire having a conductor made of aluminum (meaning aluminum or aluminum alloy) among all the electric wires. Further, the “ wire bundle 50” may be a thin wire having a conductor made of copper (meaning copper or copper alloy) among a plurality of wires. The configuration of the “wire bundle 50” is the same in the present invention. That is, the “wire bundle 50” suitable for the present invention is a bundle of a plurality of wires including at least one wire having an aluminum conductor or a thin wire having a conductor made of a metal other than aluminum. It is a thing. The “thin wire” means a wire having a small diameter for signal transmission or the like. Furthermore, the “electric wire bundle 50” in the present invention may be attached with a binding band, a protector or the like. The “electric wire” in the present invention means a round electric wire having a round cross section, an FFC having a flat cross section, or the like.

  The connector 51 includes a conductive terminal fitting electrically connected to the conductor of the electric wire, and an insulating connector housing which is provided in a box shape and accommodates the terminal fitting. The connector 51 is connected to a connector of the electronic device.

Further, the “allowable bending radius of the wire bundle 50” means a limit bending radius at which the conductor can be kept from being disconnected when the wire bundle 50 is bent. For this reason, it is possible to reliably prevent the wire bundle 50 from being bent beyond the allowable bending radius.

That is, it is preferable that the “protruding portion” has a curved outer surface, that is, an outer peripheral surface. Furthermore, the "projecting portion", the radius of curvature of the curved surface is preferably larger than the allowable bending radius of the wire bundle 50.

  As shown in FIG. 2, the wire harness 5 having the above-described configuration is accommodated in the packaging box 4A having the above-described configuration, and is transported from the wire harness manufacturer to the automobile manufacturer. That is, the wire harness 5 is positioned between the plurality of protrusions 31 or between the protrusions 31 and the side plate 21 in a state where the wire bundle 50 is not loosened, and is bent along the outer peripheral surface of the protrusion 31. It is accommodated in the packing box 4A. By being housed in this manner, the wire harness 5 is prevented from being entangled and displaced, and is also restricted from being bent beyond its allowable bending radius.

Furthermore, even if vibration is applied to the packaging box 4A during transportation, it is possible to prevent the connectors 51 and the connectors 51 and the wire bundle 50 from colliding with each other. By these, not only electric wires having an aluminum conductor, but also thin wires having a copper conductor can be protected from damage such as disconnection. That is, the wire harness 5 can be transported without being damaged.

  Further, the packaging box 4A can accommodate various types of wire harnesses 5 having different product numbers by changing the housing shape, and there is no need to manufacture a dedicated packaging box 4A for each product number of the wire harness 5. Therefore, the cost relating to the transportation of the wire harness 5 can be reduced. Furthermore, since the packaging box 4A can use the box body 2 that has been conventionally used for transporting the wire harness, the cost for transporting the wire harness 5 can be further reduced.

The wire harness 5 is positioned between the protrusions 32 or between the protrusions 32 and the side plates 21. Moreover, since the protrusion part 32 is formed in the column shape, that is, since the outer peripheral surface has the protrusion part 32 comprised by the curved surface, the electric wire bundle 50 is damaged by contacting this protrusion part 32. Can be prevented.

  Further, the protrusion 32 has a bottom surface, that is, a cross section on the plate 30, which is a perfect circle or an ellipse, and a radius of the perfect circle or a short radius of the ellipse on the plate 30 is larger than an allowable bending radius of the wire bundle 50.

The protrusion 37 has a perfect circle in a cross section orthogonal to the central axis, and the radius of the perfect circle is larger than the allowable bending radius of the wire bundle 50. For this reason, it is possible to reliably prevent the wire bundle 50 from being bent beyond the allowable bending radius.

  The chamfered portion 36 is attached to the four corners 23 facing the bottom of the box body 2 by attaching the insole member 3E to the box body 2, and between the two side surfaces of the box body 2 intersecting each other, that is, between the side plates 21. Tie with a curved surface.

  According to the wire harness packaging structure 1E of the present invention described above, the wire harness 5 is assembled on the work table or the wiring board, and then the center part is gripped and lifted, and is accommodated in the packaging box 4E. . At this time, the wire harness 5 is gripped and lifted by the center portion so that the terminal portion hangs down and becomes an inverted U-shaped state. And it is accommodated in the packaging box 4E, without changing a shape largely by mounting on the board 35 formed in spherical shape. Furthermore, when the wire harness 5 is housed in the packaging box 4E and transported, and taken out of the packaging box 4E again by the automobile manufacturer, the center portion is gripped and lifted so that the terminal portion hangs down and is in an inverted U-shaped state. However, the wire harness 5 housed in the packaging box 4E without being greatly changed in shape by being placed on the plate 35 formed in a spherical shape is also greatly changed in shape at this time. It is taken out from the packaging box 4E without. For this reason, the bending degree of the wire harness 5 is suppressed, and damage to the electric wire bundle 50 including the electric wire having an aluminum conductor and the thin electric wire having a copper conductor is suppressed to a minimum.

  Moreover, since the four corners 23 facing the bottom of the box body 2 are covered by the chamfered portion 36 in the packing box 4E, the wire harness 5 may be caught by the four corners 23 when the wire harness 5 is taken out from the packing box 4E. Is prevented. For this reason, the damage to the electric wire bundle 50 comprised with the electric wire which has a conductor made from aluminum, and the thin electric wire which has a conductor made from copper is suppressed to the minimum.
