  However, in the fixing structure of the wire harness 110 of the first conventional example, it is difficult to reliably fix the wire harness 110 including the fixing reference position only by the adhesive force of the adhesive tape.

  In the wire harness fixing structure of the second conventional example, the wire harness 110 can be reliably fixed at the fixed reference position, but the wire harness 110 is fixed in a fixed direction at the fixed reference position, and thus the routing workability is poor. There is a problem.

  Therefore, the present invention has been made to solve the above-mentioned problems, and provides a fixture for a wire harness that can reliably fix the wire harness to a vehicle body panel and that can improve the workability of the routing. The purpose is to do.

  The present invention provides a panel side fixing member fixed to a vehicle body panel and a harness side rotating member to which a wire harness is fixed and which is rotatably attached to the panel side fixing member. It is a fixture.

  According to the present invention, since the wire harness is fixed to the vehicle body panel by the panel-side fixing member and the harness-side rotating member, the wire harness can be fixed more reliably than the adhesive tape, and the direction of the wire harness can be changed by the rotation of the harness-side rotating member. As a result, the workability of the wiring harness can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  An embodiment using the fixture A of the wire harness of the present invention will be described with reference to FIGS. 1 to 8. As shown in FIG. 1, in the roof liner 1 which is a vehicle body panel, the upper surface (the back surface of the ceiling), which is the rear surface side of the roof liner 1 when viewed from the vehicle interior, is the harness wiring surface. The wire harness 5 is routed on the harness routing side. A double-sided adhesive tape 3 is adhered to the wiring surface of the roof liner 1 for wiring the wire harness 5 at a position along the harness wiring position.

  The roof liner 1 has a substantially quadrangular shape, and ears 2 are projectingly provided at four corners thereof. One corner of the roof liner 1 (near one ear 2) is the fixed reference position of the wire harness 5. The fixed reference position of the wire harness 5 is a reference position when the wire harness 5 is arranged on the roof liner 1. Specifically, the wire harness 5 is first fixed at the fixed reference position, and then the wiring work is sequentially performed from the fixed reference position.

  The wire harness 5 is wound with a tape. In the wire harness 5, the trunk wire (electric wire bundle) W is branched into a first electric wire (electric wire bundle) W1 and a second electric wire (electric wire bundle) W2 in the vicinity of the tip side slightly from the fixed reference position. The first electric wire W1 is branched from the third electric wire W3 on the way. The second electric wire W2 has a fourth electric wire W4 and a fifth electric wire W5 branched at two points on the way. A connector 4 is attached to each tip of the first to fifth electric wires W1 to W5.

  The wire harness 5 is fixed to the roof liner 1 by the fixture A at the fixed reference position and by the above-mentioned double-sided adhesive tape 3 at positions other than the fixed reference position. Hereinafter, the structure of the fixture A will be described.

  The fixture A includes a panel side fixing member 10 fixed to the roof liner 1 and a harness side rotating member 20 to which the wire harness 5 is fixed and which is rotatably attached to the panel side fixing member 10.

  The panel-side fixing member 10 is installed between the two fixing plate portions 11 fixed to the roof liner 1 and the standing portion 12 between the two fixing plate portions 11, and is spaced above the surface of the roof liner 1. and the insertion plate portion 13 arranged with the space d. The two fixing plate portions 11 are fixed to the roof liner 1 with an adhesive (not shown). The adhesive is a hot melt, a thermoplastic adhesive or the like, and hot melt is preferable. On the inner surfaces of the two erected portions 12, restriction surfaces 12a that restrict the rotation range of the harness side rotating member 20 are formed.

  A gap surrounded by the two standing portions 12 and the insertion plate portion 13 is formed in a space into which a lower plate portion 26 of the harness side rotating member 20 described below is inserted. As shown in FIGS. 4 and 5, the two restriction surfaces 12a are formed in a tapered shape that widens from the insertion inlet side toward the insertion intermediate position.

  A circular hole 14 which is a panel-side rotation center is formed in the insertion plate portion 13. The circular holes 14 penetrate the front and back surfaces of the insertion plate portion 13. The locked surface of the insertion plate portion 13 is formed as an arc surface 13a.

  The harness side rotating member 20 includes a harness fixing portion 21 that fixes the wire harness 5, and a rotating body portion 25 that is integrally provided on the harness fixing portion 21. The harness fixing portion 21 fastens and fixes the harness base 22, the band portion 23 having one end connected to the harness base 22, and the trunk line W of the wire harness 5 placed on the harness base 22 with the band portion 23. And a locking portion (not shown). On the upper surface of the harness base 22, a loose arc-shaped harness mounting groove 22a is formed over an upper plate portion 27 described below.

  The rotating body 25 includes a lower plate portion 26 extending from the harness base 22 and an upper plate portion 27 also extending from the harness base 22 and arranged in parallel with the lower plate portion 26 with a space therebetween. Have. An insertion groove 28 is formed which is formed by a gap between the lower plate portion 26 and the upper plate portion 27 and into which the insertion plate portion 13 is inserted with almost no gap.

  An engaging claw portion 29 is provided at the tip of the lower plate portion 26. The locking claw portion 29 locks on the front end surface of the insertion plate portion 13 inserted into the insertion groove 28 in the insertion direction. The locking claw portion 29 positions the insertion plate portion 13 at the insertion position and prevents the insertion plate portion 13 inserted into the insertion groove 28 from being pulled out.

  The locking surface of the locking claw portion 29 is formed as an arc surface 29a having the same radius of curvature as the arc surface 13a of the insertion plate portion 13. On the lower surface of the upper plate portion 27, a columnar protrusion 30 which is a panel side rotation center portion to be inserted into the circular hole 14 of the insertion plate portion 13 is provided. The tip end portion of the cylindrical protrusion 30 is formed on a tapered surface 30 a that gradually protrudes from the inlet side of the insertion groove 28 toward the inner side. The tapered surface 30a allows the insertion plate portion 13 to smoothly ride over the cylindrical projection 30.

  That is, in the harness side rotating member 20, the arcuate surface 29a of the locking claw 29 is guided by the arcuate surface 13a of the insertion plate 13 within the range of restriction of the pair of restricting surfaces 12a of the panel side fixing member 10. At the same time, it is rotatably attached to the panel side fixing member 10 with the columnar protrusion 30 as the center of rotation.

  Next, a procedure for arranging the wire harness 5 on the roof liner 1 will be described. The double-sided adhesive tape 3 is attached to the routing route of the roof liner 1 along the harness routing route. Further, the panel side fixing member 10 is fixed to the fixing reference position of the roof liner 1 (one corner, near the ear 2) with an adhesive. Further, the main wire W of the wire harness 5 is fastened and fixed to the harness side fixing member 20 by the band portion 23.

  Next, as shown in FIG. 7A, the harness side rotating member 20 is brought closer to the panel side fixing member 10, and the insertion plate portion 13 of the panel side fixing member 10 is inserted into the insertion groove 28 of the harness side rotating member 20. Plug in. Then, the columnar projection 30 of the harness side rotating member 20 is fitted into the circular hole 14 of the insertion plate portion 13. Further, the locking claw portion 29 of the lower plate portion 26 is locked to the circular arc surface 13a of the insertion plate portion 13. As a result, the fixture A is assembled, and the harness side rotating member 20 becomes rotatable with respect to the panel side fixing member 10.

  Next, as shown in FIG. 8, the first electric wire W1 and the second electric wire W2 of the wire harness 5 fixed by the fixing tool A at the fixed reference position are stretched without slack along each desired wiring direction (FIG. 8). Further, the third electric wire W3, the fourth electric wire W4, and the fifth electric wire W5 are extended without slack along each desired wiring direction, and fixed to the roof liner 1 via the double-sided adhesive tape 3.

  Here, the direction of the trunk line W of the wire harness 5 at the fixed reference position can be changed by rotating the harness side rotating member 20. Therefore, when the first electric wire W1, the second electric wire W2 and the like are extended without slack, the main wire W can be operated while changing the desired direction at the fixed reference position. As a result, the wiring harness 5 can be positioned easily and accurately while performing the routing work without slack.

  As described above, the fixture A of the wire harness 5 includes the panel-side fixing member 10 fixed to the roof liner 1 and the harness side to which the wire harness 5 is fixed and rotatably attached to the panel-side fixing member 10. And a rotating member 20.

  Therefore, since the wire harness 5 is fixed to the roof liner 1 with the fixtures (the panel-side fixing member 10 and the harness-side rotating member 20) A, the wire harness 5 is stronger than the adhesive force of the adhesive tape, that is, can be reliably fixed, and the harness Since the direction of the wire harness 5 can be changed by the rotation of the side rotating member 20, the workability of dispatching is improved. In addition, the length of the wire harness 5 can be adjusted (absorbed) by changing the direction of the wire harness 5.

  The panel-side fixing member 10 is provided on the two fixing plate portions 11 bonded to the roof liner 1, the inserting plate portion 13 provided between the two fixing plate portions 11, and the inserting plate portion 13. The harness side rotating member 20 has a circular hole 14 and a harness fixing portion 21 for fixing the wire harness 5, and a rotation main body 25 integrally provided on the harness fixing portion 21. Is an insertion groove 28 into which the insertion plate portion 13 is inserted, a locking claw portion 29 that prevents the insertion plate portion 13 inserted into the insertion groove 28 from being pulled out, and a circular hole 14 in the insertion plate portion 13. And a cylindrical projection 30 that is inserted into the.

  Therefore, the panel side fixing member 10 can be rotatably attached to the harness side rotating member 20 by one action of inserting the inserting plate portion 13 of the panel side fixing member 10 into the inserting groove 28 of the harness side rotating member 20. Therefore, the harness side rotating member 20 can be easily attached to the panel side fixing member 10.

  The panel-side fixing member 10 may be set to a height dimension that can secure a gap into which the lower plate portion 26 of the rotating main body 25 enters from the surface of the roof liner 1, and the harness-fixing portion 21 of the harness-side rotating member 20 is a panel. The height may be set so as to sandwich the side fixing member 10. As a result, the fixture A can be configured as a low-profile component as in this embodiment. Therefore, the wire harness 5 can be arranged in a space having a small installation dimension in the height direction.

  The panel-side fixing member 10 is formed with two restricting surfaces 12 a that restrict the rotation range of the harness-side rotating member 20. Therefore, the excessive rotation of the wire harness 5 can be prevented, and the workability of dispatching is improved.

  As shown in FIGS. 4 and 5, the two restricting surfaces 12a of the panel-side fixing member 10 are formed in a tapered shape that widens from the insertion inlet side toward the insertion intermediate position. The workability of inserting the lower plate portion 26 of 20 is good. That is, since the space surrounded by the two standing portions 12 and the insertion plate portion 13 is a space that is not visible or difficult for the operator to see, it is not necessary to insert the lower plate portion 26 into an accurate position. It can be inserted, and since the tapered surface of each regulation surface 12a guides the lower plate portion 26 after insertion, insertion workability is good.

  Since the circular arc surface 29a of the locking claw portion 29 is locked to the circular arc surface 13a of the insertion plate portion 13, the harness-side rotating member smoothly and reliably rotates on the panel-side fixing member.

  In the above embodiment, the circular hole 14 is provided as the panel side rotation center of the panel side fixing member 10 and the columnar protrusion 30 is provided as the harness side rotation center of the harness side rotation member 20. The side rotation center may be a combination structure that rotatably supports the harness side rotation member. For example, the columnar protrusion 30 may be provided as the panel side rotation center of the panel side fixing member 10, and the circular hole 14 may be provided as the harness side rotation center of the harness side rotation member 20.

  In the above embodiment, the fixture A is provided at the fixed reference position in the wiring harness 5 arrangement, but it may be provided at other positions. In the said embodiment, you may provide in the branch position of the 3rd, 4th, 5th electric wires W3-W5, for example.

  In the above-described embodiment, the wire harness 5 is fixed to the roof liner 1 by the double-sided adhesive tape 3 at positions other than the fixed reference position, but any means that can fix the wire harness 5 to the roof liner 1 may be used, such as clip fastening. But good.
