The wiring jig 1 has a wiring head 4 (see FIG. 2) for wiring an electric wire 5 to be described later by a one-stroke method above the electric wire winding body 2, and the electric wire winding is performed by a control means (not shown). The rotation of the attachment body 2 and the operation of the wiring head 4 are controlled.
[0009]
The wire winding body 2 is rotated in the direction of the arrow shown in FIG. 2 around the rotation shaft 2a by a driving means (not shown). However, depending on the circuit pattern, the wire wound body 2 can be rotated in reverse at a desired position to wire the wire 5 in a U-shape. The electric wire holder 3 has locking pieces 3a formed on both sides, a plurality of storage grooves 3b formed in the width direction, and a terminal groove 3c crossing each storage groove 3b.
[0010]
The wiring head 4 is movable in the axial direction of the rotating shaft 2 a, pulls out the electric wire 5 from a drum (not shown) corresponding to the rotation of the electric wire winding body 2, and sends it out to the electric wire winding body 2.
In manufacturing the wiring body, first, the wire holder 3 is inserted into each insertion portion 2b of the wire winding body 2, and the wire winding body 2 is rotated as shown by an arrow as shown in FIG. Then, the electric wire 5 is sent out from the wiring head 4. Thereby, the wiring apparatus 1 winds the electric wire 5 supplied from the wiring head 4 around the electric wire wound body 2 in the manner of one stroke and moves the wiring head 4 in the axial direction of the rotary shaft 2a. However, the electric wire 5 is accommodated using the plurality of accommodating grooves 3b of each electric wire holder 3, and arranged in a desired shape.
[0011]
Thus, when the electric wire 5 is wound around the electric wire wound body 2 and the wiring of the electric wire 5 to a desired shape is completed, the electric wire 5 is placed at a desired position, for example, as shown in FIG. Cut in the vicinity of
And if the electric wire 5 is removed from the electric wire winding body 2 with the some electric wire holder 3, the wiring body 6 shown in FIG. 4 by which the electric wire 5 was wired by the desired shape will be obtained.
[0012]
As described above, in the method of the present invention, the electric wire 5 is wound around the electric wire winding body 2 in which the plural electric wire holders 3 are arranged, and the wiring head 4 is moved in the axial direction of the rotary shaft 2a. In the method of the present invention, the electric wire 5 is housed in the plurality of housing grooves 3b formed in the electric wire holder 3 in this way, arranged in a desired shape, the electric wire 5 is cut at a desired position, and then the electric wires 5 are plural. The wiring body 6 is manufactured by removing it from the wire wound body 2 together with the wire holder 3. Therefore, according to the method of the present invention, the wiring body 6 can be manufactured in a short time with the wiring device 1 having a simple structure, it is not necessary to use a dedicated wiring board, and the circuit design can be easily dealt with. be able to.
[0013]
The wiring body 6 manufactured in this way is assembled into an electrical junction box as follows.
First, as shown in FIG. 5, the wiring body 6 is stored in the upper case 11 in which the bus bar wiring body 15 in which a plurality of bus bars 16 (not shown) and insulating plates 17 are alternately stacked is previously stored. At this time, the insulating plate 17 has a plurality of press contact terminals 16a and tab terminals 16b of the bus bar 16 protruding from appropriate positions, and an insertion hole 17a for press-fitting the locking piece 3a of the wire holder 3 in the vicinity of the press contact terminals 16a. Is formed. Further, the upper case 11 is a flat box, and an attachment bracket 11a is formed on the outside, and is fitted to a lower case 12 described later.
[0014]
Accordingly, when the wiring body 6 is press-fitted into the corresponding insertion hole 17a and attached to the bus bar wiring body 15 with the respective locking pieces 3a of the plurality of electric wire holders 3, the respective press contact terminals 16a correspond to the corresponding terminals of the electric wire holder 3. The corresponding bus bars 16 that are fitted into the grooves 3c are connected to the electric wires 5 and housed in the upper case 11 as shown in FIG.
At this time, each electric wire 5 is pressed from above with an appropriate jig, and is securely connected to the corresponding press contact terminal 16a. Moreover, you may connect each electric wire 5 with the corresponding press-contact terminal 16a by crimping | compression-bonding or welding. On the other hand, since each electric wire holder 3 is attached by press-fitting each locking piece 3a into the insertion hole 17a of the insulating plate 17, adverse effects such as warpage of the insulating plate 17 and poor attachment to the bus bar wiring body 15 due to other external forces. Can be prevented.
[0015]
Here, instead of the locking piece 3a, the wire holder 3 used in the wiring body 6 is a protruding boss 3d that engages with an engagement hole 17b formed in the insulating plate 17, as shown in FIG. Also good.
Next, as shown in FIG. 8, the lower case 12 is fitted into the upper case 11 in which the wiring body 6 is accommodated, and the electric connection box 10 is assembled. The lower case 12 is a flat box, and a connector housing 12a is formed at a position corresponding to the plurality of tab terminals 16b.
[0016]
As described above, the electrical junction box 10 is manufactured in a short time with the wiring device 1 having a simple structure, and the wiring body 6 that does not use a dedicated wiring board is accommodated in the upper case 11 and the lower case 12. Since it is manufactured, it is possible to easily cope with a design change of the circuit, and it can be manufactured at low cost.
Here, instead of the locking piece 3a, the wire holder 3 used in the wiring body 6 is a locking protrusion 3e as shown in FIG. 9, and is formed on the bus bar 16 and protrudes from the insulating plate 17. The joining piece 16c and the locking projection 3e may be engaged.
[0017]
In such a case, as shown in FIG. 10, the wiring body 6 is attached to the insulating plate 17 by being engaged with a plurality of corresponding engaging pieces 16 c in an inverted state. Thus, in the wiring body 6, the respective press contact terminals 16 a of the bus bars 16 are fitted into the corresponding terminal grooves 3 c of the electric wire holder 3, and the corresponding bus bars 16 are connected together by the electric wires 5. For this reason, unlike the wiring body 6 shown in FIG. 6, it is not necessary to push each electric wire 5 into the accommodation groove 3b one by one with an appropriate jig.
[0018]
In addition, the electric wire holder 3 used in the wiring body 6 covers the electric wire 5 in a desired shape so that the electric wire 5 is not detached from the plurality of storage grooves 3b before being attached to the bus bar wiring body 15. 7 (see FIG. 12) may be attached.
At this time, the electric wire holder 3 is provided with a locking projection 3f for locking the locking piece 7a (see FIG. 12) of the cover 7. For this reason, the wiring apparatus 1 forms the some insertion part 2b which inserts the electric wire holder 3 according to the external shape of the electric wire holder 3, as shown in FIG. As shown in FIG. 12, the cover 7 has locking pieces 7b on both sides in the longitudinal direction of the main body 7a, and the main body 7a is formed with slits 7c extending in the longitudinal direction. Further, the cover 7 is formed with concave grooves 7e on the side walls 7d formed on both sides in the width direction of the main body 7a so as to correspond to the plurality of storage grooves 3b.
[0019]
And as shown in FIG. 12, the wiring apparatus 1 winds the electric wire 5 supplied from a wiring head (not shown) around the electric wire winding body 2 in the way of one-stroke writing, and the said wiring head Are moved in the axial direction of the rotary shaft 2a, and the electric wires 5 are wired in a desired shape by using the plurality of storage grooves 3b of the electric wire holders 3.
Thus, when the electric wire 5 is wound around the electric wire wound body 2 and the wiring of the electric wire 5 to a desired shape is completed, the cover 7 is attached to the electric wire holder 3 as shown in FIG. Is cut at a desired position, for example, in the vicinity of the wire holder 3, and is removed from the wire wound body 2 to obtain the wiring body 6.
[0020]
As shown in FIG. 13, the wiring body 6 manufactured in this way attaches each electric wire holder 3 to the bus bar wiring body 15 at a portion corresponding to a plurality of press contact terminals 16 a. Then, in the wiring body 6, each press contact terminal 16a is fitted into the corresponding terminal groove 3c of the electric wire holder 3 so that the corresponding bus bars 16 are connected to the electric wires 5, and as shown in FIG. 15 is attached.
[0021]
At this time, since the cover 7 is attached to each electric wire holder 3 in the wiring body 6, the cover 7 is prevented from being lifted off from the housing groove 3 b of the electric wire 5 until being attached to the bus bar wiring body 15. Therefore, handling becomes easy.
Here, another embodiment according to the method of the present invention for improving the workability at the time of removing from the wiring device 1 and manufacturing a wiring body in consideration of prevention of contact between the bus bar and the electric wire will be described below.
[0022]
First, as shown in FIG. 15, an electric wire holder 22 is attached to an insulating sheet 21 made of a synthetic resin such as PET (polyethylene terephthalate) and vinyl chloride having flexibility. The electric wire holder 22 is configured in substantially the same manner as the electric wire holder 3, and a plurality of storage grooves 22b are formed in the body 22a in the width direction, and a terminal groove 22c crossing each storage groove 22b is formed in the center.
[0023]
Next, as shown in FIG. 16, the insulating sheet 21 is fixed so as to be wound around the wire winding body 2 of the wiring device 1. Next, after the electric wire 23 is laid out in a desired shape in the same manner as described above, the electric wire 23 is cut at a desired position, for example, near the cut of the insulating sheet 21 as shown in FIG. Thus, the wiring body 20 is obtained.
[0024]
Therefore, also in this embodiment, the wiring body 20 can be manufactured in a short time with the wiring device 1 having a simple structure, and it is not necessary to use a dedicated wiring board, and it is easy to change the circuit design. It can correspond to.
The wiring body 20 manufactured in this way is attached to a bus bar wiring body 15 in which a plurality of bus bars 16 and an insulating plate 17 are laminated as shown in FIG. Thereby, in the wiring body 20, each press-contact terminal 16a of the bus bar 16 is fitted into the corresponding terminal groove 22c of the electric wire holder 22, and the corresponding bus bars 16 are connected to the electric wire 23, and the wiring board shown in FIG. 25.
[0025]
If the wiring board 25 manufactured in this way is housed in the upper case 31 and the lower case 32 as shown in FIG. 20, it is simple and inexpensive, and can easily cope with circuit design changes. It is possible to manufacture an electrical junction box 30 that can be used.
Here, the upper case 31 has mounting brackets 31b formed on both sides of the main body 31a, and a mounting portion 31c for mounting various electrical components and a connector housing 31d for mounting a connector.
[0026]
On the other hand, the lower case 32 is fitted with the upper case 31 to form a box, and an insertion hole 32b through which the tab terminal 16b is inserted is formed in the main body 32a. As shown in the figure, the wiring board 25 is turned over and stored. .
Here, the wiring body that improves the workability when removing from the wiring device 1 and takes into consideration the prevention of contact between the bus bar and the electric wire is different from the above embodiment, as shown in FIG. A plurality of electric wire holders 26 may be attached to the electric wire winding body 2, and the insulating sheet 27 may be wound around the electric wire winding body 2 and fixed from above.
[0027]
As illustrated, the electric wire holder 26 has a plurality of storage grooves 22b formed in the width direction in the main body 26a. The insulating sheet 27 has openings 27a (see FIG. 22) formed at positions corresponding to the electric wire holders 26.
In manufacturing the wiring body, first, as shown in FIG. 22, an insulating sheet 27 is wound around the wire wound body 2 to which a plurality of wire holders 26 are attached. At this time, each electric wire holder 26 protrudes above the insulating sheet 27 through the opening 27a.
[0028]
Next, as shown in FIG. 23A, the electric wire 23 is sent out from the wiring head 4 while rotating the electric wire winding body 2 as indicated by an arrow. Thereby, the wiring apparatus 1 winds the electric wire 23 supplied from the wiring head 4 around the insulating sheet 27 in a manner of one stroke, and moves the wiring head 4 in the axial direction of the rotary shaft 2a. The electric wires 23 are wired in a desired shape using the plurality of storage grooves 26a of the electric wire holders 26.
[0029]
In this way, when the wiring of the electric wire 23 to the desired shape is completed, the insulating sheet 27 is further wound around the electric wire 23 as shown in FIG.
After that, the electric wire 23 is cut at a desired position, for example, in the vicinity of the cut of the insulating sheet 27 as shown in FIG.
And if the electric wire 23 is removed from the electric wire winding body 2 and the several electric wire holder 26 with the some insulating sheet 27, the wiring body 28 shown in FIG. 24 by which the electric wire 23 was wired by the desired shape will be obtained. Therefore, also in the manufacturing method of the wiring body of this embodiment, since a wiring body is easy to remove from the wiring apparatus 1, workability | operativity improves and the contact with a bus-bar and an electric wire is prevented.
[0030]
The wiring body 28 manufactured in this manner is attached to a bus bar wiring body (not shown) in the same manner as described above, and the corresponding bus bars are connected to each other by the electric wires 23 to form a wiring board, which is housed in a case and is connected to an electric junction box. It is said.
On the other hand, the wiring device to which the wiring body manufacturing method of the present invention is applied can be rotated at the same time as the rotating shaft 41a as in the wiring device 40 shown in FIG. The wire wound body 41 having a diameter may be enlarged in diameter or length, and a large number of wire holders 42 may be attached, and a plurality of wiring heads 43 may be provided correspondingly to wire the wires 44 in a desired shape. . At this time, the wire wound body 41 may be constituted by a plurality of divided bodies, and the diameter may be changed by making the plurality of divided bodies expandable and contractable in a radial method.
[0031]
Moreover, you may manufacture a wiring body using the wiring apparatus 45 demonstrated below based on this invention. Here, as shown in FIGS. 26 and 27, the wiring device 45 includes an electric wire winding body 46, a wiring head 48, and a pressure contact head 54, which will be described later, and rotation of the electric wire winding body 46 by control means (not shown). The operations of the wiring head 48 and the pressure contact head 54 are controlled.
[0032]
The wire winding body 46 has a rotating shaft 46a, and a plurality of insertion portions 46b into which the wire holders 47 are inserted are formed. The wire winding body 46 is rotated in the direction of the arrow shown in FIG. 27 about the rotation shaft 46a by a driving means (not shown). Depending on the circuit pattern, the wire wound body 46 can be rotated in reverse at a desired position, and the wire 5 can be wired in a U-shape.
[0033]
First, as shown in FIG. 26, the electric wire holder 47 is inserted into each insertion portion 46 b of the electric wire winding body 46. Here, the electric wire holder 47 is provided with a plurality of storage grooves 47b in the main body 47a, and an opening 47c is formed on the back surface.
Next, as shown in FIG. 27, the electric wire 5 is sent out from the wiring head 48 while rotating the electric wire winding body 46 as indicated by an arrow. Thereby, the wiring apparatus 45 winds the electric wire 5 supplied from the wiring head 48 around the electric wire winding body 46 in the manner of one stroke writing, and the wiring head 48 is rotated around the rotating shaft 46a of the electric wire winding body 46. The wire 5 is wired into a desired shape using the plurality of storage grooves 47b of each wire holder 47 while moving in the axial direction.
[0034]
Thus, when the electric wire 5 is wound around the electric wire wound body 46 and the wiring of the electric wire 5 to a desired shape is completed, the electric wire 5 is placed at an appropriate position near the electric wire holder 47 as shown in FIG. Disconnect.
And if the electric wire 5 is removed from the electric wire winding body 46 with the some electric wire holder 47, as shown in FIG. 29, the precursor 49 of the wiring body by which the electric wire 5 was wired by the desired shape will be obtained.
[0035]
Next, as shown in FIG. 30, the precursor 49 is turned over from the state shown in FIG. 29 and attached to the bus bar wiring body 50 via the insulating spacer 53.
Here, like the bus bar wiring body 15, the bus bar wiring body 50 is formed by alternately stacking a plurality of bus bars 51 and insulating plates 52. The bus bar 51 is provided with a plurality of press contact terminals 51a and tab terminals 51b at appropriate positions. The insulating plate 52 is formed with insertion holes (not shown) at positions corresponding to the pressure contact terminals 51 a and the tab terminals 51 b, and the pressure contact terminals 51 a and the tab terminals 51 b are inserted into these insertion holes so that the upper surface of the bus bar wiring body 50. Or protrudes from the bottom. On the other hand, the insulating spacer 53 is provided with a plurality of insertion portions 53a and rib-like insertion portions 53c formed in a rectangular tube shape through which the plurality of press contact terminals 51a are inserted as shown in the drawing. Each insertion portion 53a is formed with a holding groove 53b, and the insertion portion 53c is formed with a plurality of insertion holes 53d through which the tab terminal 51b is inserted.
[0036]
Thereby, the precursor 49 of the wiring body is attached to the bus bar wiring body 50 via the insulating spacer 53 as shown in FIG. In this state, as shown in the figure, the press contact head 54 is lowered from above, and the electric wires 5 held in the plurality of storage grooves 47b of the electric wire holders 47 are pressed from the openings 47c. Thereby, the press contact head 54 removes the electric wire 5 from the electric wire holder 47, and makes it hold | maintain in the holding groove 53b of the corresponding insertion part 53c.
[0037]
Then, after the electric wires 5 are transferred from all the electric wire holders 47 to the holding grooves 53b of the insulating spacer 53, when only the electric wire holders 47 are removed from the bus bar wiring body 50, a wiring body 55 shown in FIG. 32 is obtained.
Thus, since the wiring body 55 is manufactured using the wiring device 45 having a simple structure based on the present invention, it can be manufactured in a short time, and there is no need to use a dedicated wiring board. It is possible to easily cope with circuit design changes.
[0038]
Here, as shown in FIG. 33, a plurality of electric wire holding portions 58a having the same structure as the electric wire holder 47 shown in FIG. 30 are provided, the electric wire holding portion 58a has a storage groove 58b for storing the electric wires 5, and a back surface. A wiring body may be manufactured by using two electric wire holding plates 58 formed with openings 58c (see FIG. 34) in an overlapping manner.

When the wiring of the electric wire 5 is completed, the electric wire 5 is cut at the end of the electric wire holding plate 58 or at an appropriate position and divided into two electric wire holding plates 58. If it does in this way, since it can be wired by one wiring operation | work to the two electric wire holding plates 58, the time which manufactures a wiring body can be shortened.
[0039]
Thereafter, the electric wire holding plate 58 is turned over and attached to the bus bar wiring body 50 via the insulating spacer 53 as described above, as shown in FIG. Then, similarly to the above, the electric wire 5 is removed from the electric wire holding portion 58a by the press contact head 54, held in the holding groove 53b of the corresponding insertion portion 53c, and the electric wire holding plate 58 is removed. Thereby, the wiring body 55 shown in FIG. 32 can be manufactured in a shorter time.
[0040]
