2. Description of the Related Art A pressure contact connector, which uses wire crimp type terminal fittings, can make the connector housing smaller and the wire thinner than a crimp connector, and is suitable for a minute current circuit such as a control signal line. Therefore, a wire harness using a pressure contact connector (hereinafter, referred to as "pressure contact type wire harness") is used for electric wiring of consumer equipment, electronic equipment, automobiles and the like.

When manufacturing a press-contact type wire harness, it is not necessary to remove the coating on the end of the wire, to peel off the wire, and to crimp the metal terminal to the peeled end of the wire. Therefore, conventionally, when manufacturing a pressure contact type wire harness, a completed form of the wire harness is made on a wiring board. That is, a plurality of press-connecting connectors are previously arranged at predetermined positions on the wiring board, and one end of the electric wire is press-contacted to the press-connecting terminal of the predetermined press-connecting connector, and then the electric wire is directed toward another press-connecting connector on the wiring board. A wire-bonded wire harness is manufactured by wire-laying the wire, wire-bonding the wire on the wire-bonding plate to a wire-bonding terminal of the wire-bonding connector, cutting the wire, and repeating the cutting.

A conventional wiring device for manufacturing the above-mentioned pressure contact type wire harness is disclosed in, for example, Japanese Unexamined Patent Publication No. 4-192219.
It is disclosed in the publication. FIG. 7 shows a schematic configuration of the wiring head disclosed in this publication. In the figure, reference numeral 1 denotes a wiring plate, and the wiring plate 1 is slidably mounted on guides 3 and 4 on both sides in the longitudinal direction of a work table 2 and rotates in a forward and reverse direction by a servo motor 5. The X-axis screw rod 6 is movable in the arrow X direction.

The workbench 2 is provided with a stand 7 on both sides of the central portion, and a guide 8 and a motor 9 are provided via the stand 7.
The Y-axis screw rod 10 which is rotated by
The composite working head 11 is mounted across the above-mentioned structure and is movable by the guide 8 and the Y-axis screw rod 10 in the arrow Y direction. The composite work head 11 is provided with a combination of an electric wire selection block 12, a wiring jig 13, and a cutting and pressure welding jig 14, and constitutes an XY traveling means. The X-axis screw rod 6 and the Y-axis screw. Rod 1
With 0, it is possible to travel in the upper space of the wiring board 1 in any direction.

Reference numeral 15 is a reel station for the electric wire W1, and a plurality of electric wire reels 16 are arranged in the reel station 15. The electric wire feed motor 17 can supply the plural electric wires W1 to the electric wire selection block 12. It is said that. In other words, a plurality of wiring receiving corner pins 20 for holding the press-connecting connectors 18 and a plurality of wiring corner pins 20 are provided in advance on the wiring plate 1, and the X-axis screw rod 6 and the Y-axis screw rod 10 are used. , The composite work head 11 is moved in the X-Y directions to press one end of the electric wire W1 to the press contact terminal of one connector and then route it to the other connector, where the electric wire is pressed and cut. The pressure contact type wire harness is manufactured by sequentially repeating this.

[0007]

In the wiring apparatus shown in FIG. 7, since the composite work head 11 is provided with the electric wire selection block 12, the diameter and color of the electric wires are different in one wiring jig 13. Various electric wires can be selected and wired. By the way, with the increase of electric components in automobiles and the like, a large number of circuits using various kinds of electric wires in one wire harness are required. In order to cope with this, in the above wiring apparatus, the electric wires to be wired must be frequently selected by the electric wire selection block 12, and the selection work becomes complicated, and the production efficiency is reduced. there were.

Therefore, it is conceivable to provide a plurality of combined work heads to cope with the problem. However, in the configuration of the wiring device, even if a plurality of work heads are provided, significant improvement in production efficiency cannot be expected. For example, three composite work heads 11a, 11b, 11c are provided, and
When manufacturing the pressure contact type wire harness as shown in (a), as shown in FIG. 8 (b), the three work heads 11a, 11b, 11c are operated in time series to perform wiring. There must be. FIG. 8B is a diagram schematically showing the relative movement of the combined work head and the wiring board.

That is, as shown in FIG. 8 (b), the work head 11a is used for wiring,
After pressing one end of the electric wire W1 to the press contact connector C1 with a, the wiring board 1 is moved by X1 in the X axis direction so that the press contact connector C2 is located under the work head 11a, and the work head 11a causes the electric wire W1 to move. The other end to the crimp connector C
Press on 2. After that, the wiring board 1 is returned to the home position, and then the work head 11b performs wiring. In the wiring by the working head 11b, first, one end of the electric wire W2 is pressed against the pressure contact connector C1, and then the wiring board 1 is moved in the X-axis direction, and the working head 11b and the wiring board 1 are displaced from a predetermined position. The wiring board 1 is moved in the Y-axis direction so as to be moved by Y2 in the Y-axis direction at an angle θ2. When the wiring board 1 moves from the home position by X2 in the X-axis direction and the work head 11b and the pressure contact connector C3 correspond to each other, the work head 11b presses the other end of the electric wire W2 against the pressure contact connector C3. . When the press contact with the press contact connector C3 is completed, the wiring board 1 is returned to the home position, and then the work head 11c performs wiring.
The wiring by the work head 11c is performed by pressing one end of the electric wire W3 to the pressure contact connector C1 by the work head 11c, then moving the wiring board 1 in the X-axis direction, and from the predetermined position, the work head 11c and the wiring board 1 are moved. The wiring board 1 is moved in the Y-axis direction so that and move by Y3 in the Y-axis direction with a displacement angle of −θ3. And the wiring board 1 is X from the home position.
When the work head 11c and the press contact connector C4 correspond to each other by moving X3 in the axial direction, the work head 11c presses the other end of the electric wire W3 to the press contact connector C4. That is, although the three work heads 11a, 11b, 11c are provided, the three work heads 11a, 11b, 11c cannot be operated simultaneously and must be run in the XY direction in a time series. The production efficiency does not improve so much.

By the way, no matter how complicated the circuit structure of the pressure contact type wire harness is, as shown in FIG.
The branch lines always branch off from the main line. That is, at the time of wiring, each pressure contact connector C1, C
Wires W1, W2, W between C2, C3, C4, C5 and C6
3, W3, W4, W5, W6, W7, and W8 always have a portion wired along the main line direction (X axis) even if the distance is long or short. Therefore, the inventors have moved a plurality of wiring heads simultaneously in the X-axis direction during wiring,
The wiring head is a branch line point (corner part) A, B, C,
When D, E, and F, if the wiring head can be independently moved in the branch line direction, the production efficiency of the pressure contact type wire harness will be greatly improved.

In view of the above, it is an object of the present invention to provide a wiring device capable of simultaneously wiring a plurality of circuits and greatly improving the production efficiency of a pressure contact type wire harness.

[0012]
