To obtain a waterproof structure filled with solidified water-stopping agent 6.
[0003]
However, in such a method of manufacturing a wire harness, a minute gap remains between the wires 4 adjacent to each other at the grommet insertion site, and external rainwater is transmitted through the wire 4 due to a capillary phenomenon caused by the minute gap. There is a problem that a sufficient waterproof effect cannot be obtained.
[0004]
Therefore, in order to seal the gap between the electric wires 4, a manufacturing method shown in FIGS. 6 and 7 has been proposed.
The wire harness manufacturing method shown here is disclosed in Japanese Patent Laid-Open No. 10-224960, and a wiring board 11 for brazing and forming a wire group of wire harnesses W into a wiring form on a vehicle. On the top, a plurality of wire group receiving jigs 15a, 15b, 15c, 15d, 15e,...

The alignment jig 13 has a pair of electric wire holding members 14 fixedly arranged at predetermined intervals on a base 13 a fixed to the wiring board 11.
[0005]
Each electric wire holding member 14 forms a slit 14a for inserting an electric wire with one end opened by a pair of opposing arms 14b and 14c. The slit width of the slit 14a is selected so that the wire groups at the grommet insertion site of the wire harness W are aligned one by one vertically.
Further, the spacing between the pair of wire holding members 14 is determined according to the length of the portion of the wire harness W that is bundled in the waterproof structure.
[0006]
The waterproof structure of the grommet insertion portion of the wire harness using the alignment jig 13 is formed by the procedure shown in FIGS.
That is, first, as shown to (a), the several electric wire which passes the grommet insertion part of the wire harness W is respectively put into each slit 14a of a pair of electric wire holding members 14 and 14 spaced apart. The wire group 16 at the grommet insertion site is vertically aligned in a single plane. Next, as shown in (b), the non-solidified water-stopping agent 19 is applied to the surface of the electric wire group 16 aligned between the pair of slits 14a by the water-stopping agent applying nozzle 18. As the water-stopping agent 19, a moisture-curing silicone RTV is generally used.
[0007]
Next, as shown in (c), a strip-like film 21 for bundling the electric wire group 16 is attached to one surface of the electric wire group 16 to which the water blocking agent 19 is applied, and the electric wires are connected in an aligned state. After that, the alignment jig 13 is lowered as shown by an arrow C, and the electric wire group 16 is removed from the alignment jig 13.
Next, as shown in (d), the belt-like film 21 is wound and the electric wire group 16 is bundled into an electric wire bundle having a circular cross section. Furthermore, as shown in (e), the tape 23 is wound around the binding position of the belt-like film 21, and the cross-sectional dimension of the wire bundle is shaped into a circular shape that fits tightly into the grommet harness insertion hole, and a water-stop agent Then, as shown in (f), the grommet 25 is mounted on the winding position of the tape 23.
[0008]

As described above, the operation of inserting one electric wire into each of the slits 14a and 14a of the pair of separated electric wire holding members 14 and 14 is very time-consuming and causes a decrease in productivity of the wire harness. It was.
[0009]
Further, in the case of the electric wire holding member 14 described above, the width of the slit 14a for holding the electric wire is fixed, so when the outer diameter of the electric wire is changed, a new electric wire holding member having a corresponding slit width is added. There was also a problem that it had to be remanufactured and it was not possible to respond quickly to changes in the diameter of the wire harness.
[0010]

It is good to spread it.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a wire harness aligning wire holding member and a wire harness aligning method according to the present invention will be described in detail with reference to the drawings.
1 and 4 show an embodiment of an electric wire holding member for wire harness alignment according to the present invention.
[0017]
The electric wire holding member 35 according to this embodiment is configured by aligning a plurality of electric wires 34 in a portion penetrating the vehicle body panel in a row in order to bundle the portions of the wire harness W penetrating the vehicle body panel into a waterproof structure. Used in the step of applying a liquid medicine.
[0018]
Moreover, the electric wire holding member 35 of this embodiment is fixedly mounted on an alignment jig on a wiring board (see FIG. 6) for brazing and forming a group of electric wires into a wiring form on a vehicle. Unlike the case, the wiring board is separate from the wiring board.For example, the wiring harness on the wiring board is installed so that it can be advanced and retracted from above, and it is attached to the required part of the wiring harness routed on the wiring board. By applying later, the electric wire group at the attachment site is aligned in a row.
[0019]
As shown in the figure, the electric wire holding member 35 of the embodiment includes a first arm 35b extending in a direction intersecting the wire harness W routed on a wiring board and the like, and a first arm There is provided a second arm 35c disposed opposite to the first arm 35b with an interval through which the wire harness W can be inserted.
[0020]
In the case of the present embodiment, both the first arm 35b and the second arm 35c are made of a rod-shaped material. Further, the base end of the second arm 35c is slidably fitted to the base end of the first arm 35b, and the first arm 35b is connected to the first arm 35b by a sliding operation in the direction indicated by an arrow (A) in FIG. The interval between them is adjustable.
That is, a slit 35a that is a gap through which the wire harness W is inserted is secured between the first arm 35b and the second arm 35c. The width of the slit 35a is equal to or greater than the outer diameter of the wire harness W. Can be adjusted by a sliding operation of the second arm 35c from the size of 1 to the size of about one wire 34.
The electric wire holding member 35 sandwiches and holds the electric wire 34 of the wire harness W with the first arm 35b and the second arm 35c.
[0021]
The wire harness aligning method according to the present invention uses the above-described electric wire holding member 35 to form a line of aligned portions at the required locations of the wire harness W. First, as shown in FIG. The first arm 35b and the second arm 35c are set so that the distance w1 between the first arm 35b and the second arm 35c of the holding member 35 is larger than the outer diameter of the wire harness W. By inserting the wire harness W through the slit 35a formed between the first arm 35b and the second arm 35c, as shown by an arrow (b) in FIG. The group of electric wires 34 inserted between the first arm 35b and the second arm 35c is pressed so that the electric wires 34 constituting the wire harness W are aligned in a line.
[0022]
3 and 4 show the case where the distance between the first arm 35b and the second arm 35c is adjusted to a separation dimension in which two electric wires 34 are arranged two by two, and further the first arm 35b and the second arm. By narrowing the interval 35c, a plurality of electric wires 34 can be vertically aligned in a row.
[0023]
When the above-described electric wire holding member 35 is used for applying a water-stopping agent to form a line of aligned portions on the wire harness W over a predetermined length, 2 in FIG. Two wire holding members 35 are used as added by the dotted line.
Then, the electric wires 34 are aligned by the respective electric wire holding members 35 at the positions close to each other, and then one electric wire holding member 35 is held as shown by an arrow (c) in FIG. By sliding on 34 and widening the interval between the electric wire holding members 35 to a predetermined width, a line of aligned portions can be easily formed over a predetermined length.
[0024]
In the wire holding member 35 and the wire harness aligning method using the wire holding member 35 described above, the distance between the first arm 35b and the second arm 35c of the wire holding member 35 is set in advance. If the outer diameter of the bundle of electric wires 34 constituting the harness W is set to be larger than the outer diameter, a plurality of electric wires 34 of the wire harness W can be collectively held by the electric wire holding member 35 by one insertion operation. Thus, unlike the case of the conventional electric wire holding member 35 in which the slit width is fixed, it is not necessary to insert the electric wires 34 one by one through the slit.
When the wire 34 bundle of the wire harness W is inserted between the first arm 35b and the second arm 35c of the wire holding member 35, the first arm 35b and the second arm 35b on the wire holding member 35 side are inserted. With a simple operation of narrowing the distance from the arm 35c, the group of the plurality of electric wires 34 held by the electric wire holding member 35 can be pressed and easily aligned in a row.
Therefore, it is possible to greatly reduce the labor for holding the plurality of electric wires 34 constituting the wire harness W in an aligned state, thereby greatly improving workability.
[0025]
In addition, since the distance between the first arm 35b and the second arm 35c can be adjusted even if the diameter of the electric wire 34 to be held is changed, the distance between the first arm 35b and the second arm 35c is adjusted. By simply improving the versatility of the electric wire holding member 35, it is possible to respond quickly to a change in the diameter of the electric wire 34 of the wire harness W without the need to recreate the electric wire holding member 35.
Therefore, an increase in the wire holding member 35 prepared in the manufacturing process of the wire harness W or the like can be suppressed, and the manufacturing cost can be reduced by saving the management cost of the wire holding member 35 and jigs.
[0026]
In addition, the specific mechanism which enables adjustment of the space | interval of the 1st arm and 2nd arm of an electric wire holding member is not restricted to said embodiment.
In order to keep the cost low, a simple mechanism is desirable, but it goes without saying that various known slide mechanisms can be applied.
[0027]
In addition, the wire harness to be processed in the present invention is not limited to a wire harness for an automobile. This is useful for various types of wire harnesses that need to be aligned in a single line in the manufacturing process and the routing process.
Furthermore, the use of the present invention is not limited to the application of a water stop agent for obtaining the waterproof structure shown in the above embodiment. For example, the present invention can be applied to a case where line alignment is necessary for connector connection work or the like, and can be used in various other work processes where line alignment is required.
[0028]
Moreover, the wire holding member for wire harness alignment of the present invention is movably equipped with respect to the wiring board for brazing and forming the wire harness into the wiring form, and is completely independent from the wiring board and the like. By using it as a portable general-purpose tool, it can be used for a wider range of applications.
[0029]

Unlike the conventional wire holding member in which the wire holding member can be held by operation and the slit width is fixed, it is not necessary to insert the wires one by one through the slit.
And if the wire bundle of the wire harness is inserted between the first arm and the second arm of the wire holding member, the distance between the first arm and the second arm on the wire holding member side is reduced. With a simple operation, a plurality of electric wires held by the electric wire holding member can be pressed and easily aligned in a row.
Therefore, it is possible to greatly reduce the labor for holding the plurality of electric wires constituting the wire harness in an aligned state, thereby greatly improving workability.
[0030]
Even if the diameter of the electric wire to be held is changed, the distance between the first arm and the second arm can be adjusted. Therefore, it is allowed only by adjusting the distance between the first arm and the second arm. In addition, by improving the versatility of the electric wire holding member, it is possible to respond quickly to a change in the electric wire diameter of the wire harness and the like without having to recreate the electric wire holding member.
Therefore, an increase in the types of electric wire holding members prepared in the manufacturing process of the wire harness can be suppressed, and the manufacturing cost can be reduced.
