Abstract

<P>PROBLEM TO BE SOLVED: To appropriately proceed a dimension management of a wire harness when a wire harness for a vehicle is three-dimensionally cabled to a protector. <P>SOLUTION: After a dimension managing component 11 is attached to a predetermined position of a wire harness W by using a positioning jig 21, the wire harness W is attached to a protector through the dimension managing component 11. With this, the wire harness W is already managed on its size by the dimension managing component 11 at attaching to the protector. Therefore, a trouble in which the size is changed at assembling to the protector can be avoided. And also, since there is no need to use a jig at attaching to the protector, assembling workability is improved. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a wire harness routing method suitable for being applied when three-dimensionally routing a wire harness for a vehicle to a protector.

  FIG. 17 is a front view illustrating a conventional wire harness routing method.

Conventionally, when the wire harness W for a vehicle is routed to the protector 1, the connector 28 is pressed against the jig 27 by receiving the connector 28 attached to the end of the wire harness W as shown in FIG. Dimension management has been performed so that the dimension L1 between the protective member 1 and the protector 1 has a specified length (see, for example, Patent Document 1).
JP 11-213782 A (paragraph [0002] column, FIG. 8)

  However, in this case, in the case of three-dimensional wiring, as shown in FIG. 17, the harness outlet 9 that faces the direction intersecting the wiring jig surface 26 (for example, the direction perpendicular to the wiring jig surface 26). For the wire harness W coming out of the wire harness W, it is impossible to install the receiving jig for the connector 30 attached to the terminal on the wiring jig surface 26. There was a problem that it was not possible.

  In view of such circumstances, an object of the present invention is to provide a wire harness routing method capable of appropriately managing the dimensions of a wire harness even in the case of three-dimensional routing.

First, the invention of the wire harness routing method according to claim 1 is a wire harness routing method for routing a wire harness to a protector, and a dimension management component attaching step for attaching a dimension management component to a predetermined position of the wire harness. And a harness attachment step of attaching the wire harness to the protector via the dimension management component.
Moreover, in the invention of the wire harness routing method according to claim 2, in the dimension management component mounting step, the dimension management component is positioned at a normal position of the protector using a positioning jig. .
The wire harness routing method according to a third aspect of the invention is characterized in that, in the harness mounting step, the dimension management component is fitted into an engagement groove of the protector.
In the wire harness routing method according to a fourth aspect of the present invention, the dimension management component includes an engagement portion that is fitted into the engagement groove of the protector in a slide-lock manner.
In the wire harness routing method according to a fifth aspect of the present invention, the dimension management component includes an engaging portion that is press-fitted into the engaging groove of the protector.
The wire harness routing method according to claim 6 is characterized in that the dimension control component is provided with the engaging portion at each opening of a cylindrical main body.

  According to the present invention, when the wire harness is attached to the protector, since the dimension is already managed by the dimension management component, it is possible to avoid the problem that the dimension changes when the wire harness is assembled to the protector. Therefore, even in the case of three-dimensional routing, it becomes possible to appropriately carry out dimension management of the wire harness.

  Moreover, since it becomes unnecessary to use a jig | tool at the time of attachment to a protector, assembly workability | operativity improves.

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

FIG. 9 and FIG. 9 are perspective views showing the fitted state of the dimension management component shown in FIG.

  As shown in FIG. 3, the protector 1 has a bowl-shaped protector body 2, and a harness outlet 8 is formed in the protector body 2. In addition, two lids 3 and 4 are attached to the protector body 2 so as to be freely opened and closed in a form that can be rotated via hinges 5 and 6, respectively. One lid 3 is provided with an engaging groove 7 so as to be closed by the other lid 4 to form a harness outlet 9. As shown in FIG. 8, a pair of locking locking portions 10 is formed in the engagement groove 7, and notches 16 are formed on the left and right sides of the entrance of the engagement groove 7.

  Further, as shown in FIGS. 4 to 7, the slide lock type dimension management component 11 is of a split hinge open / close type and has a cylindrical main body 12. On the inner peripheral surface of the main body 12, as shown in FIG. 5, a locking claw 12 a with which a bellows-like corrugated tube 29 is engaged is formed in an arc shape. In addition, a U-shaped clip-shaped engaging portion 13 is formed in one opening of the main body 12, and a pair of locking latching claws 15 are formed in the engaging portion 13.

  Further, as shown in FIG. 1, a receiving jig 27 and a positioning jig 21 are erected on the routing jig surface 26. As shown in FIG. 2, the positioning jig 21 has a support column 22, and a U-shaped tube cradle 23 is mounted on the upper side of the support column 22. Furthermore, a locking claw 24 with which the corrugated tube 29 is engaged is formed in the tube receiving base 23 in an arc shape.

  And when wiring the wire harness W to the protector 1 three-dimensionally, it follows the following procedure.

  First, in the harness tying step, the wire harness W is tied on the routing jig surface 26, and the corrugated tube 29 is attached to an appropriate place of the wire harness W.

  Next, the process proceeds to a dimension management part attaching step, and the dimension management part 11 is attached to the wire harness W as shown in FIG. At this time, the connector 28 attached to the end of the wire harness W is pressed against the receiving jig 27, and the positioning jig 21 is used so that the dimension L2 between the connector 28 and the dimension management component 11 becomes a specified length. Perform dimension management. In addition, since the dimension management component 11 is a split hinge opening / closing type, the attachment work to the wire harness W can be performed easily and rapidly.

  Finally, it transfers to a finishing process, removes the wire harness W from the wiring jig surface 26, and attaches the wire harness W to the protector 1 via the dimension management component 11, as shown in FIG.

  That is, first, as shown in FIG. 3 (a), in the state where both the lids 3 and 4 of the protector 1 are open, the dimension management component 11 is connected to the harness of the protector 1 as shown in FIG. 3 (b). Engage with outlet 8. Next, as shown in FIG. 3C, the wire harness W is bent and raised by 90 °, and then the lid 3 of the protector 1 is closed. Then, the lid 4 is closed as shown in FIG. Then, the dimension management component 11 is prevented from falling off by the lid body 4 and is attached to the normal position (engagement groove 7) of the protector 1. When the engaging portion 13 slides to the depth of the engaging groove 7, the locking claw 15 is hooked and engaged with the locking locking portion 10 as shown in FIGS. The part 11 does not reverse. When the engaging portion 13 slides to the depth of the engaging groove 7, the engaging portion 13 engages with the notch 16, so that the dimension management component 11 protrudes to the lid body 4 side and the lid body 4 cannot be closed. Does not occur.

  Thus, the wire harness W is attached to the protector 1 via the dimension management component 11 and protrudes from the harness outlet 9 in the finishing process. At this time, since the dimension of the wire harness W is already managed by the dimension management component 11, it is possible to avoid a problem that the dimension changes when the protector 1 is assembled. Moreover, since it is not necessary to use the receiving jig 27 at this time, assembly workability | operativity improves.

  Here, the work of three-dimensionally routing the wire harness W on the protector 1 is completed.
