[Prior art]
Conventionally, as shown in FIG. 6, a clamp 1 for fixing to a vehicle body is attached to a wire harness W / H, and a trunk line W− of the wire harness W / H is attached to a wire harness routed in an automobile. When it is necessary to connect the connector 2 such as a joint connector to the tip of the branch line W-2 branching from 1, and to hold the connector 2 to the wire harness W / H, the adhesive tape 3 is used for the connector. 2 is wound around the wire harness W / H and fixed.
[0003]
[Problems to be solved by the invention]
As shown in FIG. 7, the mounting order of the clamp 1 and the connector 2 with respect to the wire harness W / H is only to wrap the connector 2 using the adhesive tape 3 after the clamp 1 is attached to the wire harness W / H. As shown in FIG. 8, there is a variation in the position and direction of the connector 2 with respect to the clamp 1.
[0004]
Therefore, when the wire harness W / H is routed in the automobile, the connector 2 comes into contact with the stepped portion 4a of the vehicle body 4, the clamp attachment surface 4b of the vehicle body 4, or an external interference material other than the vehicle body. In such a case, there is a problem that abnormal noise is generated due to vibration generated when the automobile is running, and there is a problem that the connector 2 is damaged.
[0005]
Furthermore, both of the work of attaching the clamp 1 to the wire harness W / H and the work of attaching the connector 2 are necessary, and there is a problem that the number of work is increased.
[0006]
The present invention has been made in view of the above-described problems, and restricts the position of the connector 2 with respect to the clamp so that it does not come into contact with the vehicle body, and allows the clamp and the connector to be easily attached to the wire harness. The task is to improve work efficiency.
[0007]
