Moreover, the terminal metal fitting for connecting to the electronic device mentioned above is attached to the terminal of the 1st electric wire 2 and the 2nd electric wire 3. FIG.

  As shown in FIGS. 1 and 3, the wiring clip 4 is provided in a flat mounting portion 10 and a hole 21 provided in a panel 20 (indicated by a two-dot chain line in FIG. 3) that constitutes the body of an automobile. A locking portion 11 to be locked is integrally provided. The wiring clip 4 is made of synthetic resin. The attachment portion 10 is formed in a band plate shape. The attachment portion 10 is overlapped with the first electric wire 2 of the wire harness 1, and a tape (not shown) is wound around the outer periphery together with the first electric wire 2. The attachment portion 10 is attached to the first electric wire 2 of the wire harness 1 by winding a tape. At this time, the longitudinal direction of the attachment portion 10 and the surface of the attachment portion 10 are along the longitudinal direction of the first electric wire 2 of the wire harness 1.

  The locking part 11 is erected from the mounting part 10. The locking part 11 is integrally provided with a standing piece 13 erected from the mounting part 10 and a pair of locking pieces 14. The standing piece 13 extends from the attachment portion 10 along a direction orthogonal to the surface of the attachment portion 10.

  The pair of locking pieces 14 have one end portion 14 a continuous with the tip portion 13 a on the side away from the mounting portion 10 of the standing piece 13. The tip portion 13a is an end portion on the side away from the mounting portion 10 of the standing piece 13. The other end portions 14 b of the pair of locking pieces 14 are spaced from each other and spaced from the standing piece 13.

  The pair of locking pieces 14 are arranged in a state of gradually approaching the attachment portion 10 from the one end portion 14a toward the other end portion 14b. The pair of locking pieces 14 are gradually separated from each other and gradually separated from the standing piece 13 as they go from the one end portion 14a to the other end portion 14b. The pair of locking pieces 14 are formed in a mountain shape when viewed from the side. A notch 17 is provided at the other end 14 b of the locking piece 14. The cutout 17 cuts out the outer edge portion of the other end portion 14 b of the locking piece 14. The pair of locking pieces 14 can be elastically deformed in a direction in which the other end portions 14b approach each other.

  When the locking portion 11 is press-fitted into the hole 21, the locking piece 14 is elastically deformed in a direction in which the other end portions 14 b approach each other, and then the inner edge of the hole 21 of the panel 20 is formed in the notch 17. When positioned, the locking piece 14 returns to the neutral state where it is not elastically deformed. And the latching | locking part 11 positions the inner edge of the hole 21 of the panel 20 in the notch 17, and is fixed to the panel 20 mentioned above.

Attach to 20.

  The harness tube 5 is made of an insulating synthetic resin and is formed in a cylindrical shape. The harness tube 5 is formed in a bellows shape with convex portions and concave portions provided alternately in the longitudinal direction. For this reason, the harness tube 5 is elastically deformable. The harness tube 5 protects the second electric wire 3 by passing through the second electric wire 3 on the inner side, that is, by being sheathed on the second electric wire 3. The inner diameter of the harness tube 5 is larger than the outer diameter of the second electric wire 3. That is, the harness tube 5 and the second electric wire 3 are movable with respect to each other along the longitudinal direction.

  The corrugated tube 6 is made of an insulating synthetic resin and is formed in a cylindrical shape having an oval cross section (oval or elliptical). The corrugated tube 6 is formed in a bellows shape with convex portions and concave portions provided alternately in the longitudinal direction. For this reason, the corrugated tube 6 is elastically deformable.

  The tape 7 is wound around the outer periphery of the mounting portion 10 of the wiring clip 4, the first electric wire 2, and the harness tube 5 to fix them together. The tape 7 is not directly wound around the outer periphery of the second electric wire 3. That is, the tape 7 does not fix the second electric wire 3, the mounting portion 10 of the wiring clip 4, the first electric wire 2, and the harness tube 5 to each other.

  According to the present embodiment, the tape 7 fixes the wiring clip 4 and the harness tube 5, that is, the tape 7 is not directly wound around the outer periphery of the second electric wire 3. The tube 5 is movable along the longitudinal direction. For this reason, even if the electric wires 2 and 3 are wired linearly as shown in FIG. 2 or the electric wires 2 and 3 are bent about 180 degrees as shown in FIG. If wrinkles are to occur, the second electric wire 3 and the harness tube 5 move along the longitudinal direction.

  That is, even if the electric wires 2 and 3 positioned linearly as shown in FIG. 2 are bent at the time of routing as shown in FIG. 4, the second electric wire 3 and the harness tube 5 move relatively. . Therefore, even if the electric wires 2 and 3 are bent at the time of routing, the electric wires 2 and 3 and the harness tube 5 move relatively, so that the electric wires 2 and 3 are wrinkled or the tape 7 is used as the wiring clip 4. Thus, the wire harness 1 can be routed without being separated from the normal position.

  Since the tape 7 as the fixing member is used, the tape 7 can securely fix the wiring clip 4 and the harness tube 5.

  Moreover, since the 1st electric wire 2 and the 2nd electric wire 3 are electric wires which supply electric power, the electric wires 2 and 3 which supply this electric power at the time of wiring, and the harness tube 5 move relatively. For this reason, the electric wires 2 and 3 can be routed without causing wrinkles in the relatively thick electric wires 2 and 3 that supply the electrodes.

  Each of the first electric wire 2 and the second electric wire 3 described above is provided. However, in the present invention, a plurality of first electric wires 2 and second electric wires 3 may be provided. In short, in the present invention, at least one first electric wire 2 and two second electric wires 3 may be provided.

  In the above-described embodiment, the wiring clip 4 is provided as an exterior product. However, in this invention, you may provide various exterior goods other than the wiring clips 4, such as a well-known harness protector and a harness tube as exterior goods.

  Further, in the above-described embodiment, the tape 7 as a fixing member is provided. However, in the present invention, various articles other than the tape 7 such as a well-known band may be provided as the fixing member. Moreover, the protection member may not be cylindrical as long as it is formed in a cylindrical shape.

  Moreover, in embodiment mentioned above, both the 1st electric wire 2 and the 2nd electric wire 3 are electric wires which supply electric power. However, in the present invention, it is desirable that at least one of the first electric wire 2 and the second electric wire 3 is an electric wire that supplies electric power. That is, in the present invention, the first electric wire 2 and the second electric wire 3 may not be electric wires that supply electric power.
