For example, the metal rod 3 can ensure a relatively large current capacity with a relatively small cross-sectional area as compared with the electric wire 2, and thus the size of the wire harness 1 </ b> A can be reduced. In addition, the 2nd conductor part 31 is not restricted to a substantially circular shape cross-sectional shape, For example, a rectangle etc. may be sufficient and it may be a cylindrical conductor structure.

  The connection structure 100 electrically connects the electric wire 2 and the metal rod 3. The connection structure 100 includes a connection part 101 and a protective sheet 102.

In addition, about the structure, an effect | action, and effect which are common in embodiment mentioned above, the overlapping description is abbreviate | omitted as much as possible (hereinafter, the same).

  A wire harness 1B according to this embodiment shown in FIGS. 5 and 6 includes a connection structure 200 in place of the connection structure 100.

The mounting portion 203 is formed on the distal end portion 31a of the second conductor portion 31 formed in a flat plate shape on the end portion on the connection portion 101 side of the first insulating coating portion 22, in other words, the second conductor portion at the connection portion 101. The end portion on the side where the first conductor portion 21 connected to 31 is exposed is placed.

  The stepped portion 204 is formed between the connection portion 101 and the end 22 a on the connection portion 101 side of the first insulating coating portion 22 formed on the second conductor portion 31 and placed on the distal end portion 31 a of the second conductor portion 31. Located in. The stepped portion 204 has a level difference h equal to the thickness t of the first insulating covering portion 22 along the direction intersecting the connection direction in the second conductor portion 31, here, the direction orthogonal to the mounting direction. This is the offset part.

  That is, in the connection structure 200, the connection portion 101 is located on one side (here the side on which the metal rod 3 extends) across the stepped portion 204 with respect to the extending direction, and the other side (here, the wire 2 extends). The placement portion 203 is located on the existing conductor side, and the portion of the second conductor portion 31 on the placement portion 203 side is less than the portion of the second conductor portion 31 on the connection portion 101 side. In other words, in the connection structure 200, the second conductor on which the portion of the second conductor portion 31 that is chamfered with respect to the portion constituting the connection portion 101 mounts the end portion on the connection portion 101 side of the first insulating coating portion 22.

  The first insulation coating portion 22 placed on the second conductor portion 31 has an end 22a on the connection portion 101 side positioned at least on the placement portion 203 side with respect to the stepped portion 204. In a state of being abutted against the attaching portion 204, the protective sheet 102 is bound. That is, the protective sheet 102 of the present embodiment is configured as an insulating member that covers the entire circumference of the connection portion 101, the placement portion 203, and the stepped portion 204.

  According to the connection structure 200 described above, the conductive first conductor portion 21 formed by the plurality of strands 21a and the insulating first insulating covering portion 22 that covers the outer peripheral side of the first conductor portion 21.

For example, the connection portion 101 can be configured to prevent disconnection of each strand 21a. In addition, since the connection structure 200 and the wire harness 1B are covered with the insulating protective sheet 102 around the entire circumference of the connection portion 101 and the placement portion 203, the connection portion 101 and the placement portion 203 are reinforced. The first conductor part 21 and the second conductor part 31 are peeled off at the connection part 101, and the second conductor part 31 and the first insulating coating part 22 are peeled off at the mounting part 203. Can be suppressed. As a result, the connection structure 200 and the wire harness 1B can connect the electric wire 2 and the metal rod 3 more appropriately.

  Furthermore, according to the connection structure 200 and the wire harness 1 </ b> B described above, the second conductor portion 31 is formed in a flat plate shape with the connection portion 101 and the portion constituting the placement portion 203. The end 22a on the connection part 101 side is abutted against the stepped part 204. Therefore, in the connection structure 200 and the wire harness 1B, when connecting the first conductor portion 21 of the electric wire 2 and the second conductor portion 31 of the metal rod 3, the end 22a of the first insulating covering portion 22 of the electric wire 2 is stepped. The first conductor portion 21 and the second conductor portion 31 are connected in a state in which the relative positional relationship with the second conductor portion 31 is positioned in an appropriate positional relationship by being brought into contact with the portion 204. can do. Therefore, the connection structure 200 and the wire harness 1B are assembled in the relative positional relationship between the first conductor portion 21 of the electric wire 2 and the second conductor portion 31 of the metal rod 3, particularly in the extending direction (connection direction or Since the assembly position accuracy with respect to the axial direction of the metal rod 3 can be improved, connection reliability can be improved in this respect as well.
