2. Description of the Related Art In a wire harness grommet, an electric wire insertion tube portion for inserting a wire harness is provided in a central portion of an annular fitting and locking portion which is fitted and locked in a through hole of a partition plate of a vehicle body or the like. A wire harness having a basic structure, which penetrates a partition plate by inserting and setting a wire harness through the wire insertion tube part and fittingly locking the outer periphery of the fitting locking part to a through hole on the vehicle body side. While maintaining the disposition posture, the penetration portion is waterproofed.

A hood opener for an automobile, which is installed side by side with the wire harness and through which a partition plate penetrates.
If cables such as a washer hose are present, those with a grommet hole through which the cables are inserted are attached to the grommet peripheral wall between the wire harness grommet fitting and locking part and the wire insertion tube part. These wire harness grommets are used and fixed to the wire harness by mounting the wire harness on the wire harness and then winding the wire harness and the wire harness together with the wire winding. To be done.

[0004]

The wire harness grommet before being fixed together with the tape winding is apt to be rotatably moved with respect to the wire harness in a temporarily mounted state through the wire harness. When working, the grommet hole position with respect to the circumferential direction of the wire harness may be fixed while it is collapsed.If the grommet in such a state is fitted and locked to the vehicle body, etc., it is difficult or impossible for the cables to be inserted into the grommet hole. Will cause a problem. Then, in order to prevent such posture collapse, special attention is required for the tape winding and fixing work, which causes a problem that workability is deteriorated.

The present invention provides a method of mounting a grommet for a wire harness, a mounting drawing board used for the method, and a mounting board jig for solving the above-mentioned drawbacks of the prior art.

[0006]

DISCLOSURE OF THE INVENTION The present invention which solves the above technical problems is to provide a wire harness grommet having a grommet hole for inserting cables in the vicinity of an electric wire insertion tube portion for inserting a wire harness. Attached to
When fixing the mounting posture by winding the wire insertion tube part and the wire harness together with the tape, the wire harness of the grommet temporary mounting with the wire harness inserted in the wire insertion tube part is used as a reference on the mounting drawing board. The regulation pin, which is held in a posture and has a predetermined relative position with respect to the reference posture, is passed through the grommet hole to adjust and set the temporary mounting posture, and then the tape in the state of the adjusting set posture. A method of attaching the wire harness grommet to the wire harness, characterized by performing co-winding and restricting and fixing the attachment position of the wire harness grommet in the circumferential direction of the wire harness. "
When,

"A wire harness grommet having a wire harness inserted therein is temporarily attached to the wire insertion gland of the wire harness grommet having a grommet hole for inserting cables in the vicinity of the wire insertion tube. A support jig that holds the insertable / removable member in a standard position is installed and installed, and the support pin has a predetermined relative position with respect to the wire harness in the standard position and can be inserted into and removed from the grommet hole. It is composed of a "mounting drawing board having a structure provided in the tool and used in the above-described mounting method" and "a jig having the restriction pin provided on the frame portion of the wire harness receiving portion".

That is, according to the mounting method and the mounting drawing board of the present invention, by inserting the regulating pin into the grommet hole of the wire harness grommet which is passed through the wire insertion tube portion and is temporarily mounted, When the position of the grommet hole with respect to the circumferential direction of the wire harness is regulated and fixed, and the grommet for the wire harness is penetratingly arranged in the partition plate of the vehicle body, when the cables are attached to the wire harness and penetrate the partition plate, It is characterized in that the position of the grommet hole is fitted to the arrangement condition. Then, at the same time as the position regulation of the grommet hole, a mounting method of two-position regulation for regulating the position of the wire insertion tube portion in the longitudinal direction of the wire harness,
It may have a mounting board configuration.

[0009]

The above-described method for mounting the wire harness grommet on the wire harness of the present invention and the mounting drawing plate used for the method are the same as the wire harness grommet in which the position of the grommet hole is regulated by the regulation pin. Since the set fixing is performed, the position of the grommet hole can be accurately set at a predetermined position in the wire harness circumferential direction, and the work of fixing the set is extremely simplified. In the case of the two-position regulation, the position regulation in the longitudinal direction of the wire harness can be performed at the same time, so that the "grommet position mark" or the like previously applied to the wire harness becomes unnecessary.
