BACKGROUND OF THE INVENTION
According to the present invention, a predetermined portion of a wire bundle in which a plurality of wires are configured in a predetermined wiring form is accommodated and protected by a protector comprising a protector body and a lid, and the wire is drawn from a harness lead-out end of the protector. The present invention relates to a method of manufacturing a wire harness that accommodates and protects a bundle with a corrugated tube, and a tape winding auxiliary jig suitable for use in the manufacturing method.
[0002]
[Prior art]
As a wire harness routed to a vehicle body in an automobile or the like, a predetermined portion of a wire bundle in which a plurality of wires are configured in a predetermined routing form is accommodated and protected by a protector including a protector body and a lid, and the protector There has been proposed a configuration in which the wire bundle drawn from the harness lead-out end portion is accommodated and protected by a corrugated tube.
And what is shown in FIG. 11 as a protector used for such a wire harness is proposed (for example, refer patent document 1).
[0003]
As shown in FIG. 11, the protector 1 includes a wire bundle 6 constituting the wire harness W / H, an end portion of the bellows-like corrugated tube 5 into which the wire bundle 6 is inserted, and an electric wire extending from the end portion. The protector main body 2 that accommodates the branch portion of the bundle 6 and the lid body 3 that is assembled to the protector main body 2 are configured.
[0004]
In the protector main body 2, one harness pull-out end portion 7 that accommodates and holds the end portion of the corrugated tube 5 is connected to one end of a bundle accommodating chamber 10 that accommodates the branch portion of the wire bundle 6, and the bundle accommodating chamber 10. Two harness pull-out end portions 8 and 9 are connected to the other end.
[0005]
Protrusions 11, 12, and 13 having U-shaped cross sections are provided on the inner surfaces of the respective harness pull-out ends 7, 8, and 9, and the corrugates corresponding to the protrusions 11, 12, and 13, respectively. The concave portions 5a of the tubes 5 are locked to prevent the corrugated tubes 5 from coming off in the axial direction.
In the peripheral wall of the corrugated tube 5, a slit 5 b for interrupting the wire bundle 6 is formed along the longitudinal direction.
[0006]
The lid 3 has curved projections 15, 16, and 17 on the inner surface that face the projections 11, 12, and 13, respectively. As a result, the protruding portions 11, 12, 13 of the harness pull-out end portions 7, 8, 9 and the curved protrusions 15, 16, 17 of the lid 3 enter the concave portion 5a of the corrugated tube 5 and move up and down. Therefore, the end portion of the corrugated tube 5 is securely held by the harness pull-out end portions 7, 8, 9 of the protector 1.
[0007]
Moreover, the shape of the branch part of the wire bundle 6 which comprises the wire harness W / H is not restricted to the example shown in FIG. The branch portion of the wire bundle 6 shown in FIG. 11 is a form that branches in a Y shape, but as shown in FIG. 12, it may branch in a T shape, and it branches into three or more from the main line. There is also a case.
The form of the protector to be used varies depending on the form of the branch part as shown in FIG. 12, but the protector is composed of a protector main body and a lid, the bundle housing chamber 10 and the harness drawer provided in the protector main body. The configuration in which the end portions 7, 8, and 9 are connected is the same as that of the protector 1 shown in FIG.
[0008]
The wire harness W / H in which the wire bundle 6 is accommodated and protected by the protector 1 and the corrugated tube 5 as described above has been conventionally manufactured by the following procedures (1) to (5).

{Circle around (2)} The wires constituting the wire harness W / H are wired so as to pass through the protector main body 2 on each wiring jig 19 to form the wire bundle 6 wired in a predetermined size and shape.
{Circle around (3)} A corrugated tube 5 is attached to the wire bundle 6 drawn out from each harness lead-out end 7, 8, 9 of the protector body 2.
(4) The lid body 3 is united so that the end portions of the corrugated tubes 5 are fixed to the harness pull-out end portions 7, 8, 9 of the protector body 2.
(5) Tape is wound around the outer periphery of the corrugated tube 5 so that the slit 5b of the corrugated tube 5 does not open.
[0009]

[0010]
[Problems to be solved by the invention]
However, in the wire harness W / H configured as described above, the open ends of the corrugated tubes 5 fixed to the harness pull-out ends 7, 8, 9 of the protector 1 may rub and damage the inserted electric wires. is there.
Therefore, in the manufacturing process of the wire harness, before covering the corrugated tube 5 on the electric wire bundle 6, it is desirable to perform the lower winding with the adhesive tape in the region corresponding to the open end of the corrugated tube 5 of the electric wire bundle 6.
[0011]
However, as shown in FIG. 12, since the protector main body 2 was set on the wiring jig 19 on the wiring board, the wire bundle 6 was routed directly on the protector main body 2. It has been difficult to perform a lower winding operation with a tape on a region corresponding to the open end of the corrugated tube 5 of the wire bundle 6.
That is, in order to wrap an adhesive tape around the wire bundle 6 routed on the protector body 2, it is necessary to lift the wire bundle 6 and secure a working space between the protector body 2 and In the case of a large harness, the wire bundle 6 itself is quite heavy, and a work space cannot be secured. Moreover, if the electric wire bundle 6 is lifted too high, the wired electric wire bundle 6 will shift | deviate and the problem that a dimensional accuracy will fall will also arise.
[0012]
Further, in order to prevent the slit 5b of the corrugated tube 5 from being opened, tape winding is necessary on the outer periphery of the corrugated tube 5, but the corrugated tube 5 held by the harness pull-out ends 7, 8, and 9 of the protector 1 is used. The end region is a tape unwound region so that the adhesive tape blocks the concave portion 5a of the corrugated tube 5 and does not hinder the protrusions 11, 12, 13 of the protector 1 from engaging the concave portion 5a. It becomes.
[0013]
That is, in order to prevent the tape from being accidentally wound around the tape unwound region, conventionally, the operator visually confirms the tape unwound region by counting irregularities at the end of the corrugated tube 5 or the like. This has been a cause of delaying the tape winding work.
[0014]
Accordingly, an object of the present invention is to solve the above-mentioned problems, and a highly reliable wire that can facilitate the lower winding work with an adhesive tape while preventing the dimensional accuracy of the wire harness and the routing workability from being deteriorated. It is to provide a method for manufacturing a harness and a tape winding auxiliary jig.

[0032]
Next, the manufacturing method of the wire harness in this embodiment is demonstrated.
As shown in FIG. 2, the tape winding auxiliary jig 21 and the wiring jigs 24 and 25 are previously placed on the wiring board 23 corresponding to the wiring path of the wire bundle 6 constituting the wire harness W / H. After placement, the following steps are performed.
[0033]
First, as shown in FIG. 4, the wires 6 a constituting the wire harness are routed on the routing jigs 24 and 25 on the wiring board 23, and the wire bundle 6 serving as the wire harness W / H is formed in a predetermined manner. Route in shape (wire routing process).
Next, as shown in FIG. 5 (a), lower winding with an adhesive tape 46 is performed in a region 45 corresponding to the open end of the corrugated tube 5 on the wire bundle 6 formed in the wire routing step (tape). Lower winding process).
[0034]
Next, as shown in FIGS. 5 (b) and 5 (c), a corrugate in which slits 5b for interrupting the wire bundle 6 are formed in the peripheral wall at predetermined positions of the wire bundle 6 that has undergone the tape lower winding process. The tube 5 is fitted and attached (tube attachment process).
And the support | pillar part 34 of the said tape winding auxiliary | assistant jig | tool 21 which was tilted until then is raised, and the said corrugated tube 5 fixed to the harness drawer | drawing-out edge part of protector 1A, 1B as shown in FIG.5 (d). The non-tape winding area 47 at the end of the tape is gripped by the pair of gripping members 36 and 37 of the tape winding auxiliary jig 21.
[0035]
Thereafter, the adhesive tape 46 is wound around the outer periphery of the corrugated tube 5 so that the slit 5b of the corrugated tube 5 is not opened, except for the tape unwound region 47 hidden by the gripping of the pair of gripping members 36 and 37. (Tape winding process).
[0036]
Next, the gripping members 36 and 37 of the tape winding auxiliary jig 21 are removed from the wire bundle 6 that has finished the tape winding process around the outer periphery of the corrugated tube 5, and the tape winding auxiliary jig 21 is returned to the tilted state. Thus, the wire bundle 6 is retracted from the route.
Then, the wire bundle 6 is slightly lifted from the routing jig 24, and the protector bodies 2A and 2B of the protectors 1A and 1B are set on the routing jig 24 as shown in FIG. 5 (e). The protector attachment area of the wire bundle 6 extending from the opening end of the corrugated tube 5 is accommodated in the bundle accommodating chamber 10 of the protector main bodies 2A and 2B.
[0037]
At this time, the concave portion 5a of the tape unwound region 47 at the end portion of the corrugated tube 5 is engaged with the protruding portion 11 on the protector body 2A, 2B side, so that the corrugated tube 5 set in the axial direction moves. Is restrained.
Thereafter, although not shown, when the lids 3A and 3B are assembled to the protector bodies 2A and 2B, the protector bodies 2A and 2B and the lids 3A and 3B are assembled to the protector attachment area of the wire bundle 6. The protector mounting process for housing and protecting is completed.
[0038]
In the tape winding step, the procedure for gripping the tape unwound region 47 at the end of the corrugated tube 5 by the pair of gripping members 36 and 37 of the tape winding auxiliary jig 21 is described with reference to FIGS. And will be described in detail.
First, as shown in FIG. 6A, the tape winding auxiliary jig 21 raises the support column 34 as shown in FIG. 6B from the state in which the support column 34 is tilted, and a pair of gripping members. After the 36 and 37 are in the open state, as shown in FIG. 7A, the tape winding impermissible region 47 at the end of the corrugated tube 5 is positioned on the locking means 39 of the one gripping member 37. . In FIG. 6, the wire bundle 6 accommodated and protected by the corrugated tube 5 is illustrated as being lifted away from the routing jig 24, but this shows the movement of the tape winding auxiliary jig 21. This is for easy understanding, and in actuality, it may be lifted slightly while being held by the routing jig 24.
[0039]
Next, as shown in FIG. 7B, the gripping members 36 and 37 are closed, and the tape unwound region 47 at the end of the corrugated tube 5 is gripped by the pair of gripping members 36 and 37.
FIG. 8 shows a state in which the tape unwound regions 47 and 47 at both ends of the corrugated tube 5 are gripped by the pair of gripping members 36 and 37 of the tape winding auxiliary jig 21, respectively, and the tape winding process described above in this state. The adhesive tape 46 is wound around the outer periphery of the corrugated tube 5 between the pair of tape winding auxiliary jigs 21 and 21, and the opening of the slit 5b is prevented.
[0040]
That is, according to the manufacturing method of the wire harness of the present embodiment described above, the lower winding with the adhesive tape 46 is applied to the region 45 corresponding to the open end of the corrugated tube 5 on the wire bundle 6 configured in a predetermined wiring form. The tape lower winding process to be performed is performed before the protector mounting process in which the protectors 1A and 1B are mounted to the wire bundle 6.
Therefore, the protectors 1A and 1B are not present during the lower winding operation using the adhesive tape 46, and the wire bundle 6 is lifted high in order to secure a work space necessary for the lower winding operation using the adhesive tape 46. There is no need, and the lower winding work by the adhesive tape 46 to the area | region 45 corresponding to the opening end of the corrugated tube 5 of the electric wire bundle 6 can be made easy. Moreover, the fall of the dimensional accuracy of the harness W / H caused by the lifting of the wire bundle 6 can be prevented, and the wire harness W / H having a high dimensional accuracy can be efficiently manufactured.
[0041]
Furthermore, in the manufacturing method of the wire harness of the present embodiment, the tape winding auxiliary jig 21 described above is used at the time of the tape winding process. By tilting the tiltable column 34 and retracting it from the wiring path of the wire bundle 6, it does not interfere with the wiring work of the wires or the work of attaching the protectors 1 </ b> A, 1 </ b> B to the wire bundle 6, Does not interfere with work.
[0042]
Then, the tape winding auxiliary jig 21 used in the present embodiment raises the pair of gripping members 36 and 37 by raising the tiltable column portion 34 during the tape winding step of winding the tape around the corrugated tube 5. When the tape winding impermissible region 47 at the end of the corrugated tube 5 can be held by the pair of gripping members 36 and 37 and the pair of gripping members 36 and 37 can be made to correspond to the routing route of the wire bundle 6, the tape unrollable region 47 becomes a pair of gripping members. Since it is covered with 36, 37, there is no fear that the adhesive tape 46 is accidentally wound around the non-tape winding area 47.
[0043]
Further, the operator only needs to wind the tape around the outer periphery of the corrugated tube 5 within a range extending from the gripping members 36 and 37 of the tape winding auxiliary jig 21. This makes it easy to wind the tape around the outer periphery of the corrugated tube 5, and at the same time reduces the working time.
[0044]
In this embodiment, the tape winding auxiliary jig 21 is used in order to prevent accidental tape winding to the non-tape winding area 47 of the corrugated tube 5, but the tape winding auxiliary jig 21 cannot be prepared. In the environment, the number of the corrugated tube 5 corresponding to the tape winding auxiliary jig 21 is clearly displayed on the wiring board 23 instead, or a mark or scale indicating the range of the tape unwinding region 47 is used. May be dealt with by attaching to the outer periphery of the corrugated tube or on the wiring board.
[0045]
Further, the configuration of the tape winding auxiliary jig according to the present invention is not limited to the configuration of the tape winding auxiliary jig 21 in the above embodiment, and various forms can be taken based on the gist of the present invention. Not too long.
For example, the locking means for locking and fixing the tape unwound region 47 is not limited to the configuration in which the protrusion 40 is engaged with the recess 5a as in the locking means 39 of the above embodiment, and an elastic pad is applied. For example, the axial movement of the corrugated tube can be restricted.
[0046]
The tape winding auxiliary jig 51 according to another embodiment of the present invention shown in FIG. 9 includes a pedestal portion 53 for fixing to the wiring base 23 by a fixing means (not shown), and a pivot pin 52 on the pedestal portion 53. And a U-shaped gripping portion 55 provided at the tip of the column portion 34.
Further, locking means 56 for locking and fixing the tape unwound region 47 of the corrugated tube 5 are provided on the inner side surfaces of the U-shaped gripping portions 55 facing each other. The locking means 56 is a curved projection that fits into the recess 5 a of the corrugated tube 5.
[0047]
When the corrugated tube 5 is press-fitted from the upper opening, the U-shaped gripping portion 55 elastically deforms the corrugated tube 5 itself in the diameter reducing direction, and the curved projection of the locking means 56 is formed on the corrugated tube 5. By engaging the recess 5a, the axial movement of the corrugated tube 5 can be restrained, and the end of the corrugated tube 5 can be firmly fixed.
That is, the tape winding auxiliary jig 51 according to the present embodiment does not require the opening / closing operation of the pair of gripping members 36 and 37 like the tape winding auxiliary jig 21 described above, and only presses the corrugated tube 5 from above. Since it is good, workability | operativity improves further.
[0048]
Further, the tape winding auxiliary jig 61 according to another embodiment of the present invention shown in FIG. 10 includes a U-shaped gripping portion 65 provided at the tip of the column portion 34.
And, on the inner side surface of the U-shaped gripping portion 65 facing each other, a locking means 66 for locking and fixing the tape unwound region 47 of the corrugated tube 5 and a stopper for bulging formed on the upper opening end side. Each of the protrusions 67 is provided.
[0049]
The locking means 66 is a curved projection that fits into the recess 5 a of the corrugated tube 5.
The retaining protrusion 67 prevents the corrugated tube 5 press-fitted from above from inadvertently coming out upward.
[0050]
Therefore, when the corrugated tube 5 is press-fitted from the upper opening, the outer periphery of the corrugated tube 5 comes into contact with the retaining protrusion 67 and elastically deforms the U-shaped gripping portion 65 itself in the widening direction. The curved projection of the locking means 66 is engaged with the concave portion 5 a of the corrugated tube 5, thereby restraining the axial movement of the corrugated tube 5 and moving the retaining projection 67 upward of the corrugated tube 5. Is restrained.
That is, the tape winding auxiliary jig 61 according to the present embodiment can reliably hold the corrugated tube 5 and can further improve the workability of the tape winding work around the outer periphery of the corrugated tube 5.
[0051]
Furthermore, in the protector mounting step of the above embodiment, the wire bundle 6 is slightly lifted from the routing jig 24, and the protector bodies 2A, 2B of the protectors 1A, 1B are set on the routing jig 24. After the protector attachment area of the wire bundle 6 extending from the opening end of the corrugated tube 5 is accommodated in the bundle accommodating chamber 10 of the protector main bodies 2A and 2B, the lid bodies 3A and 2B are accommodated in the protector main bodies 2A and 2B, respectively. Although the case where 3B was assembled was described, the present invention is not limited to this.
[0052]
For example, the protector mounting step can be performed on a finishing wiring board that also serves as an inspection step. That is, according to the method for manufacturing a wire harness of the present invention, the tape winding operation for the wire harness W / H is completed before the protector mounting step, so that the finishing tool equipped with the routing jig for dimensioning is completed. The protector main bodies 2A and 2B of the protectors 1A and 1B are set in advance on the wiring board, and the protector main body 2A and 2B accommodate the protector attachment area of the wire bundle 6 extending from the opening end of the corrugated tube 5. Thereafter, it is only necessary to assemble the respective lids 3A and 3B to the protector main bodies 2A and 2B, and the wire harness W / H with high dimensional accuracy can be efficiently manufactured.
[0053]
【The invention's effect】
According to the manufacturing method of the wire harness of the present invention as described above, the tape lower winding step of performing the lower winding with the adhesive tape in the region corresponding to the opening end of the corrugated tube on the wire bundle configured in a predetermined wiring form. This is performed before the protector mounting step of mounting the protector on the wire bundle.
[0054]
Therefore, there is no protector that interferes with the lowering work with adhesive tape, and there is no need to lift the wire bundle high to secure the work space required for the lower winding work with the adhesive tape. It is possible to easily perform the lower winding operation with the tape to the region corresponding to the open end of the corrugated tube. In addition, it is possible to prevent a decrease in the dimensional accuracy of the harness caused by lifting the wire bundle, and it is possible to efficiently manufacture a wire harness with a high dimensional accuracy.
[0055]
In addition, according to the tape winding auxiliary jig of the present invention, except during the tape winding process, by placing the tiltable support column and retracting it from the cable bundle routing path, It does not interfere with the work or the work of attaching the protector to the wire bundle, and does not hinder the work.
And, at the time of the tape winding process of winding the tape around the outer periphery of the corrugated tube, the pair of gripping members (or U-shaped gripping portions) are made to correspond to the routing route of the wire bundle by raising the tiltable support column. When a tape unwound region at the end of the corrugated tube is gripped by a pair of gripping members (or U-shaped gripping portions), the tape unrollable region becomes a pair of gripping members (or U-shaped gripping portions) ), So there is no risk of the tape being accidentally wound around the tape unwound area.
