Abstract

The routing structure according to an embodiment is an in-vehicle routing structure. The routing structure includes a first routing member and a second routing member. The first routing member includes a first conductor portion and a first fire-resistant insulating portion covering an outer periphery of the first conductor portion. The second routing member includes a second conductor portion and a second fire-resistant insulating portion covering an outer periphery of the second conductor portion. The first fire-resistant insulating portion includes an insulating fire-resistant tape wound around a peripheral surface of the first conductor portion, and a protective member covering an outer periphery of the fire-resistant tape. The second fire-resistant insulating portion includes an insulating fire-resistant film covering a peripheral surface of the second conductor portion. A thickness of the second routing member is smaller than a thickness of the first routing member.

Dependent claims

An in-vehicle routing structure comprising:

a first routing member including a first conductor portion and a first fire-resistant insulating portion covering an outer periphery of the first conductor portion;
and
a second routing member including a second conductor portion and a second fire-resistant insulating portion covering an outer periphery of the second conductor portion, wherein
the first fire-resistant insulating portion includes an insulating fire-resistant tape wound around a peripheral surface of the first conductor portion and a protective member covering an outer periphery of the fire-resistant tape,
the second fire-resistant insulating portion includes an insulating fire-resistant film covering a peripheral surface of the second conductor portion, and
a thickness of the second routing member in a second cross-section orthogonal to an extension direction of the second routing member is smaller than a thickness of the first routing member in a first cross-section orthogonal to the extension direction of the first routing member.
