DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary tying sub-harness constituting a wire harness for an automobile, and a method of manufacturing a wire harness formed from the temporary tying sub-harness.
In particular, at the time of the main binding in which the wire harness is formed from the temporary binding sub-harness, the post-insertion terminal of the temporary binding sub-harness can be surely and easily attached to the connector attached to another temporary binding sub-harness. It is to be.

[0002]

2. Description of the Related Art When manufacturing a wiring harness for an automobile, sub-harnesses are temporarily bound and formed for each electrical component to be connected, and as shown in FIG. Many temporary binding sub-harnesses 2
The wires are held and held by the upper wiring jig 3, and the wires are wrapped with tape, or a corrugated tube, a protection sheet, or the like is covered with the wires, and the wires are bundled and finally bound. In addition, required parts (clamps for securing the vehicle body, protectors, etc.) are attached to manufacture the wire harness.

[0005] As shown in FIG. 5, the sub-harnesses 2A, 2B,... Which are preliminarily bound before the final binding are, as shown in FIG. When inserted into the connector 4 connected to the electric wire of the binding sub-harness, it is in a state of being connected to the electric wire end. The post-insert terminal 5 is inserted into the post-insert connector 4 when the post-insert connector 4 is wired on the drawing board 1 shown in FIG.

[0004]

Conventionally, the operation of inserting the post-insertion terminal 5 into the connector 4 has been performed by relying on the skill of an operator. Which connector is to be inserted later is determined, and an insertion error is likely to occur. Specifically, the post-insertion terminals 5 account for about 20% of the entire terminals. In the case of a cowl harness, there are 10 to 20 sets of temporary binding sub-harnesses, and there are 30 or more post-insertion terminals 5. Therefore, it is very troublesome to insert these post-insertion terminals 5 into a required connector without fail, and errors are apt to occur as described above.

Further, the post-insertion terminal 5 is inserted after the temporary binding sub-harness to which the connector 4 for inserting the terminal is connected is wired and the connector 4 is held by the jig 3. If another temporary tying sub-harness is laid before the temporary tying sub-harness to which the 4 is connected is buried in the electric wire group. In this state, when the temporary binding sub-harness to which the connector 4 to be inserted is connected is wired and the terminal 5 is inserted into the connector 4, the electric wire w to which the terminal 5 is connected is searched for from the electric wire group, taken out, and In addition, it is necessary to draw the wire through the wire group to the connector 4 side. In addition, when the wire is drawn through the wire group as described above, the wires are entangled, the wire length becomes shorter than a required length, and the terminal 5 cannot be inserted into the connector 4 in some cases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and it is possible to easily and easily insert a post-insertion terminal of a temporary binding sub-harness into a connector connected to another temporary binding sub-harness at the time of final binding. The task is to be able to do so.

In order to solve the above-mentioned problems, the present invention is directed to a first aspect of the present invention, wherein a cloth is held on a drawing board for assembling a wire harness with a jig held upright on the drawing board. A temporary binding sub-harness that is wired and permanently bound by tape winding, wherein the same connector is connected to a terminal attached to a terminal attached to a connector attached to another temporary binding wire harness at the time of final binding; The present invention provides a temporary binding sub-harness characterized in that electric wires to be inserted later are combined with a tape or a rubber band.

[0008] As described above, if the electric wires with the terminals to be inserted later into the same connector are attached to the terminals and are wound together with tape or rubber bands, the electric wires connected to the inserted terminals are searched for one by one and inserted. Since the operation of determining the connector to be connected is reduced, the workability of inserting the terminal can be greatly improved. In addition, if a plurality of electric wires are temporarily bundled, it is easy to find the electric wires in the electric wire group, the electric wires are hardly entangled, and the number of the electric wires in the electric wire group can be reduced.

It is preferable that the tape or the rubber band be colored to identify the connector to be inserted later (claim 2). In this way, if the color of the tape or rubber band to be temporarily bound is color-coded and the destination connector of the color-coded terminal is displayed on the drawing board, it is possible to prevent an error in insertion into the connector.

Further, the present invention provides a method for manufacturing a wire harness using the temporary binding sub-harness according to claim 3 in claim 3. In other words, a tape holding the connector or the same color as the color attached to the rubber band was attached to the jig holding the connector, and the temporary binding sub-harness was assembled with the tape or rubber band. A wire harness manufacturing method is provided in which an electric wire is held through a jig of the same color, and a terminal of the electric wire is inserted into a connector held by the jig.

[0011] As described above, if the tape for attaching the post-insertion terminal or the tape of the same color as the rubber band is pasted to the jig holding the connector into which the post-insertion terminal is inserted, the temporary binding sub-harness can be wired. Each time the jig is held at a glance, the jig holding the wire group in which the post-insertion terminals are put together can be held through the jig. When the connector is held by the jig, a post-insert terminal is inserted.

According to the above method, it is possible to prevent the wire of the post-insertion terminal from being buried in the wire group, and it is possible to confirm at a glance the correspondence between the post-insertion terminal and the connector into which the terminal is inserted. No error occurs, and the workability can be greatly improved.
