Wire harness combination structure
View Patent ↗Each of wire harnesses includes a conductive path, an exterior member which covers the conductive path, a base portion which is retrofitted to or integrally formed with the exterior member, and a combination structure portion which is integrally formed with the base portion. The combination structure portion includes a combining engagement portion and a combined engagement portion. The combining engagement portion of the combination structure portion in one of the wire harnesses is detachably engaged with the combined engagement portion of the combination structure portion in the other wire harness, or the combined engagement portion of the combination structure portion in the one of the wire harnesses is detachably engaged with the combining engagement portion of the combination structure portion in the other wire harness, so that the wire harnesses are combined with each other.
1. A wire harness combination structure, comprising a plurality of wire harnesses, wherein:
each of the wire harnesses respectively comprises:
a conductive path,
an exterior member covering an outer circumference of the conductive path,
a base portion retrofitted to the exterior member or integrally formed with the exterior member as one part of the exterior member,
a self-combination structure portion, and
a combination structure portion integrally formed with the base portion;
the combination structure portion comprises:
a combining engagement portion, and
a combined engagement portion;
the self-combination structure portion comprises
a self-combining engagement portion, and
a self-combined engagement portion;
the combining engagement portion of the combination structure portion of a first wire harness of the plurality of wire harnesses is configured to detachably engage with the combined engagement portion of the combination structure portion in a second wire harness of the plurality of wire harnesses, or the combined engagement portion of the combination structure portion of the first wire is configured to detachably engage with the combining engagement portion of the combination structure portion of the second wire harness, so that the wire harnesses are combined with each other, and
the self-combining engagement portion and the self-combined engagement portion are configured to detachably engage with each other in a state that the first wire harness of the plurality of wire harnesses is bent so that opposed portions of the first wire harness can be detachably engaged with each other.
2. The wire harness combination structure according to claim 1 , wherein:
each of the plurality of wire harnesses comprises a plurality of the combination structure portions; and
the plurality of wire harnesses are configured to be engaged with one another through the combination structure portions so that the plurality of wire harnesses are combined with one another to be entirely put on top of one another in predetermined intervals.
3. The wire harness combination structure according to claim 1 , wherein the exterior member comprises a bendable tube portion which has flexibility and a non-bendable tube portion which has lower flexibility than the bendable tube portion.
4. The wire harness combination structure according to claim 1 , wherein:
the base portion comprises a clamp or a protector retrofitted to a predetermined position of the external exterior; and
the clamp or the protector comprises a fixation portion and the combination structure portion, the fixation portion being provided for fixation to a fixation subject.
5. The wire harness combination structure according to claim 1 , wherein each of the wire harnesses comprises a long portion to be arranged in a vehicle underfloor.
6. The wire harness combination structure according to claim 1 , wherein
the combining engagement portion comprises a protrusion protruding from the base portion,
the combined engagement portion comprises a recess in the base portion, a shape of the recess being formed in accordance with a shape of the protrusion, and
the combining engagement portion of the combination structure portion of the first wire harness is configured to detachably engage with the combined engagement portion of the combination structure portion of the second wire harness when inserted into the recess.
7. The wire harness combination structure according to claim 6 , wherein the protrusion of the combining engagement portion is substantially cylindrical.
8. The wire harness combination structure according to claim 6 wherein the combining engagement portion further comprises a plurality of press-fitting ribs formed on an exterior surface of the protrusion.
