Patent Document 1 JP-A-10-64651

However, the wire harness manufacturing apparatus using the connector supply apparatus 101 shown in FIG. 4 has the following problems.

That is, it is impossible to manufacture a wire harness in which a first connector C1 having a predetermined shape viewed from the side is connected to one end of a plurality of electric wires W as shown in FIG. The second connector C2 having the same shape as the first connector C1 when viewed from the side, and the third connector C3 having a different shape from the first connector C1 when viewed from the side. As shown in FIG. 6(A), the first connector C1 and the second connector C2 have the same shape when viewed from the side, and the contact arrangement pitch is relatively small. On the other hand, as shown in FIG. 6(B), the third connector C3 differs from the first connector C1 in shape when viewed from the side, and has a relatively large contact arrangement pitch.

In this way, the reason why the other end of the electric wire W cannot be manufactured is that the second connector C2 having the same shape as the first connector C1 when viewed from the side and the first connector C2 having the same shape as the first connector C1 when viewed from the side are connected. 3 The wiring harness of the connector C3 is because on the other end side of the electric wire W in the connector supply device 101 shown in FIG. , 114-3, ... are correspondingly formed with dedicated passages that match the shape viewed from the side of the first connector 114-1, 114-2, 114-3, ..., so that it is impossible to transport and connect The first connectors 114-1, 114-2, 114-3, . . . are connectors of different shapes when viewed from the side.

On the other hand, it is also conceivable to arrange the first connector C1 on one end side of the harness and arrange the second connector C2 and the third connector C3 on the other end of the harness when manufacturing a so-called multiharness. On one end side, a plurality of wires W are manually crimped to the contacts of the connectors C1, C2, and C3. The so-called multi-wire harness refers to the wire harness as shown in FIG. One end of the W is connected to a first connector C1 having a predetermined shape when viewed from the side and having a small contact pitch, and the other end of the wire W is connected to the same shape as the first connector C1 when viewed from the side. Moreover, the second connector C2 having a smaller contact arrangement pitch and the third connector C3 having a larger contact arrangement pitch are different in shape from the first connector C1 when viewed from the side.

However, since the plurality of electric wires W are crimped manually, the productivity of manufacturing the wire harness is remarkably lowered.

The single ends of the electric wires W are transported to the crimping position I, so that the single ends of the plurality of electric wires W are located at the position opposite to the crimping surface of the first connector C1 that has been transported by the first and second connector transport parts 21. position. Also, as shown in FIG. 1 and FIG. 3(C), the second electric wire conveying member 52, together with the first electric wire conveying member 51, moves from the clamping position C in the direction of the arrow f perpendicular to the axial direction, and the The opposite ends of some of the electric wires W in the plurality of electric wires W are conveyed to the crimping position I, so that the opposite ends of some of the electric wires W in the plurality of electric wires W are located at the same position as those that have passed through the first and second connector conveyance members 21. The position where the crimping surface of the second connector C2 to be transported faces. The second electric wire conveying member 52 moves from the clamping position C along the arrow f direction perpendicular to the axial direction together with the first electric wire conveying member 51, compared to the second electric wire conveying member 52 and the first electric wire conveying member 51 moving independently. , The production efficiency of the wiring harness is improved. Also, at the same time, the 3rd wire conveying member 53, as shown in FIGS. The opposite ends of the electric wires W are transported to the crimping position I, so that the opposite ends of the remaining electric wires W among the plurality of electric wires W are positioned at the distance from the third connector C3 that has been transported by the third connector transport part 22. The position where the crimping faces face each other.

Then, in the crimping step, the first crimping member 61 moves in the axial direction, and the single ends of the plurality of electric wires W and the opposite ends of a part of the plurality of electric wires W are crimped by the plunger injection press 61a. On the contacts provided on the first connector C1 and the second connector C2, on the other hand, the second crimping member 62 moves in the axial direction, and the plurality of electric wires W are drawn by the plunger type injection press 62a. The remaining opposite ends are crimped to contacts provided on the third connector C3.

In this way, as shown in FIG. 1 and FIG. 3(D), a wire harness is produced, and the wire harness is discharged from the crimping position I. The aforementioned wire harness is connected to one end of a plurality of wires W viewed from the side. The first connector C1 having a predetermined shape and a small contact arrangement pitch is connected to the opposite end with a connector C1 having the same shape as the first connector C1 when viewed from the side and a small contact arrangement pitch (contact arrangement A second connector C2 having the same pitch as the first connector C1), and a third connector C3 having a shape different from that of the first connector C1 when viewed from the side and having a larger contact arrangement pitch.

Thus, according to the present embodiment, it is possible to automatically produce a harness in which the first connector C1 having a predetermined shape as viewed from the side is connected to one end of a plurality of electric wires and connected to the opposite end of the electric wire W. A second connector C2 having the same shape as the first connector C1 when viewed from the side and a third connector C3 having a different shape from the first connector C1 when viewed from the side are connected.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this, Various changes and improvements are possible.

For example, the number of the first connector C1, the second connector C2, and the third connector C3 is not limited to one, and a plurality of them may be used.

Also, the contact arrangement pitch of the third connector C3 is relatively larger than the contact arrangement pitch of the first connector C1 and the second connector C2, but it is not the same as the contact arrangement pitch of the first connector C1 and the second connector C2. The pitch of the contact arrangement is the same. In this case, in the step shown in FIG. 2(F), it is not necessary to change the pitch of the remaining (three wires in this embodiment) opposite ends of the wires W.
