Abstract

An exterior end portion cap is configured to be attached to an electrically conductive path and an exterior member. The exterior end portion cap includes an external exposure portion having a first blocking portion, an internal insertion portion having a second block portion, and an electrically conductive path housing recess portion formed to extend across the external exposure portion and the internal insertion portion. The first blocking portion has a planar portion configured to abut against the exterior member. The second blocking portion has holding piece portions that are deformable to wind around the electrically conductive path circumferentially. The electrically conductive path housing recess portion is formed into a concave portion that is so deep that a part of an outer surface of the electrically conductive path is pressed against an inner surface of the exterior member.

First claim

What is claimed is:

1. An exterior end portion cap to be attached to an electrically conductive path and an exterior member having a tubular shape, and the electrically conductive path being led out from the exterior member, the exterior end portion cap comprising:
an external exposure portion having a first blocking portion and configured to be exposed to an outer side of the exterior member;
an internal insertion portion having a second blocking portion and being continuous to the external exposure portion; and
an electrically conductive path housing recess portion formed to extend across the external exposure portion and the internal insertion portion, wherein:
the first blocking portion is disposed on a side to which the internal insertion portion is continuous, and has a planar portion configured to abut against an end portion of the exterior member,
the second blocking portion has holding piece portions that are disposed at both sides of the electrically conductive path housing recess portion so as to be opposed to each other, and that are deformable to wind around an outer surface of the electrically conductive path circumferentially;
the electrically conductive path housing recess portion is formed into a concave portion that is so deep that a part of an outer surface of the electrically conductive path is offset and pressed against an inner surface of the exterior member near the end portion in order to make the part of the outer surface of the electrically conductive path as a third blocking portion; and
an outer diameter of the external exposure portion is larger than an outer diameter of the end portion of the exterior member,
wherein at least one vertical slit is provided such that a gap is formed in an axial direction of the exterior end portion cap between the second blocking portion and the external exposure portion, the at least one vertical slit allowing the second blocking portion to deform circumferentially to wind around the outer surface of the electrically conductive path.

2. The exterior end portion cap according to claim 1 , wherein:
a detachment preventing portion configured to be engaged with the inner surface of the exterior member is provided on an outer surface of the internal insertion portion.

3. The exterior end portion cap according to claim 1 , wherein:
a tapered portion is extended from an insertion front end portion of the internal insertion portion to the second blocking portion in an inclined direction being inclined with an insertion direction in which the insertion front end portion is inserted into the exterior member.

4. A wire harness comprising:
an exterior member having a tubular shape;
an electrically conductive path that is protected by the exterior member; and
the exterior end portion cap according to claim 1 that is attached to the electrically conductive path and an end portion of the exterior member.

5. The exterior end portion cap according to claim 1 , wherein the electrically conductive housing recess portion offsets the electrically conductive path such that a portion of the electrically conductive path within the external member is at a different elevation than a portion of the electrically conductive path outside the external member.

6. The exterior end portion cap according to claim 1 , wherein a portion of the electrically conductive path extends beyond the second blocking portion such that the extended portion is pressed against the inner surface of the exterior member.

7. The exterior end portion cap according to claim 1 , wherein a thickness of the holding piece portions reduces toward a protrusion front end position of the second blocking portion.
