Abstract

A shielded conductive path that can facilitate manufacturing operations is provided. A shielded conductive path includes a shielding pipe that is configured to have a tubular shape into which an electric wire can be inserted, by combining together a pair of divided bodies into which the shielding pipe is divided along its axis, and an overlapping fitting portion that is provided at a joint portion of the pair of divided bodies and allows the pair of divided bodies to be fitted to each other while overlapping each other in an inside-outside direction when the pair of divided bodies are combined together. Thus, the operations for manufacturing the shielded conductive path can be performed easily.

First claim

What is claimed is:

1. A shielded conductive path comprising:
a shielding pipe having a tubular shape into which an electric wire can be inserted, the shielding pipe formed by combining together a pair of divided bodies, the shielding pipe being divided along an axis of the divided bodies; and
an overlapping fitting portion that is provided at a joint portion of the pair of divided bodies and allows the pair of divided bodies to be fitted to each other while overlapping each other in an inside-outside direction when the pair of divided bodies are combined together, the overlapping fitting portion having an arc-shaped outer surface,
wherein the shielding pipe is provided with an electric wire protecting portion that covers a corner portion of the overlapping fitting portion, the corner portion being formed inside the shielding pipe.

2. The shielded conductive path according to claim 1 , wherein the overlapping fitting portion is formed on only an inner surface of the shielding pipe.

3. The shielded conductive path according to claim 1 , wherein the shielding pipe is provided with a holding portion that holds a leading end of the electric wire protecting portion or the closing portion from an inner side.

4. The shielded conductive path according to claim 1 , wherein the pair of divided bodies have the same shape.

5. The shielded conductive path according to claim 1 ,
wherein the shielding pipe is provided with a partition constituent wall that partitions an interior of the shielding pipe into a plurality of electric wire insertion spaces, and
the partition constituent wall is provided in only one of the pair of divided bodies and extends from an inner circumferential surface of said one divided body so as to partition an interior of said one divided body into the same number of spaces as the electric wire insertion spaces.

6. The shielded conductive path according to claim 1 ,
wherein the shielding pipe is provided with a partition wall that partitions an interior of the shielding pipe into a plurality of electric wire insertion spaces, and
the partition wall is formed by partition constituent walls that are provided in both of the pair of divided bodies being laid on top of each other when the pair of divided bodies are combined together, and leading end portions of the partition constituent walls are disposed overlapping each other.

7. The shielded conductive path according to claim 1 , wherein the divided body has a drain hole that is formed from a side that constitutes an inner circumferential surface of the shielding pipe toward the opposite side.

8. The shielded conductive path according to claim 1 , wherein an external shape of the shielding pipe is a circle.

9. The shielded conductive path according to claim 1 , wherein the overlapping fitting portion has a flat inner surface.

10. A shielded conductive path comprising:
a shielding pipe having a tubular shape into which an electric wire can be inserted, the shielding pipe formed by combining together a pair of divided bodies, the shielding pipe being divided along an axis of the divided bodies; and
an overlapping fitting portion that is provided at a joint portion of the pair of divided bodies and allows the pair of divided bodies to be fitted to each other while overlapping each other in an inside-outside direction when the pair of divided bodies are combined together, the overlapping fitting portion having an arc-shaped outer surface,
wherein the shielding pipe is provided with a closing portion that extends from one of the pair of divided bodies across the inside of the joint portion to the side of the other divided body.

11. The shielded conductive path according to claim 10 , wherein the overlapping fitting portion is formed on only an inner surface of the shielding pipe.

12. The shielded conductive path according to claim 10 , wherein the pair of divided bodies have the same shape.

13. The shielded conductive path according to claim 10 ,
wherein the shielding pipe is provided with a partition constituent wall that partitions an interior of the shielding pipe into a plurality of electric wire insertion spaces, and
the partition constituent wall is provided in only one of the pair of divided bodies and extends from an inner circumferential surface of said one divided body so as to partition an interior of said one divided body into the same number of spaces as the electric wire insertion spaces.

14. The shielded conductive path according to claim 10 ,
wherein the shielding pipe is provided with a partition wall that partitions an interior of the shielding pipe into a plurality of electric wire insertion spaces, and
the partition wall is formed by partition constituent walls that are provided in both of the pair of divided bodies being laid on top of each other when the pair of divided bodies are combined together, and leading end portions of the partition constituent walls are disposed overlapping each other.

15. The shielded conductive path according to claim 10 , wherein the divided body has a drain hole that is formed from a side that constitutes an inner circumferential surface of the shielding pipe toward the opposite side.

16. The shielded conductive path according to claim 10 , wherein an external shape of the shielding pipe is a circle.

17. The shielded conductive path according to claim 10 , wherein the overlapping fitting portion has a flat inner surface.
