Exterior end portion cap and wire harness

1. An exterior end portion cap to be attached to at least two electrically conductive paths and an exterior member having a tubular shape, and the at least two electrically conductive paths 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; and

an internal insertion portion having a second block portion, being continuous to the external exposure portion, and configured to be inserted into the exterior member, wherein:

the internal insertion portion has an electrically conductive path exposing slit by which a part of outer surfaces of the at least two electrically conductive paths can be made to function as a third blocking portion when the internal insertion portion is attached to the at least two electrically conductive paths;

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 a convex portion that is disposed so as to face to the at least two electrically conductive paths arranged side by side and that is fitted to a gap between the at least two electrically conductive paths arranged side by side;

the exterior end portion cap is configured to be divided into two divided parts for holding the at least two electrically conductive paths each shaped like a circle in section therebetween; and

the electrically conductive path exposing slit is disposed in a position corresponding to a position of a divided surface of the two divided parts and is formed so as to bring the part of the outer surfaces of the at least two electrically conductive paths into contact with an inner surface of the exterior member near the end portion of the exterior member in order to make the part of the outer surfaces of the at least two electrically conductive paths functions as the third blocking portion.

2. The exterior end portion cap according to claim 1 , further comprising:

a hinge that connects the two divided parts, wherein:

concavely and convexly shaped engagement portions are formed on first end portions of divided surfaces of two divided parts, second end portions of the divided surfaces of two divided parts are opposed to the first end portions and are closer to the hinge than the first end portions.

3. 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.

4. An exterior end portion cap according to claim 1 , wherein:

a tapered surface configured to be guided by the end portion of the exterior member is formed at an insertion front end portion of the internal insertion portion configured to be inserted into the exterior member.

5. The exterior end portion cap according to claim 1 , wherein:

a fixation piece for fixing the exterior member to a structure body during path routing is provided integrally on an outer surface of the external exposure portion.

6. A wire harness comprising:

an exterior member having a tubular shape;

at least two electrically conductive paths that are arranged side by side and that are protected by the exterior member; and

the exterior end portion cap according to claim 1 that is attached to the at least two electrically conductive paths arranged side by side and the end portion of the exterior member.
