In the present embodiment, the mounting direction X1 of the connector 20 is a direction orthogonal to the direction in which the band 11 protrudes.

As shown in FIG. 2, the connector 20 is previously attached to a terminal of a branch line W-2 of the wire harness W / H. Clamp 1 attached to wire harness W / H
0, first, as shown in FIG. 3, the connector 20 is lock-coupled to the connector mounting portion 14 of the clamp 10.

Next, as shown in FIG. 4A, the position and the direction of the connected connector 20 to the wire harness are determined, and the band 11 of the clamp 10 is wound around the outer periphery of the connector 20 and the wire harness W / H. As shown in FIG. 4 (B), it is inserted into the locking hole 12a of the main body 12 and tightened and fixed.

As a result, as shown in FIG.
The connector 20 can be attached to the wire harness W / H at the same time by attaching the clamp 10 to the wire harness W / H with 0 as a predetermined position of the wire harness W / H.

When the wire harness W / H is mounted on the vehicle body 4 as shown in FIG. 5B, the vehicle body locking portion 13 of the clamp 10 is inserted and locked into a locking hole 4c formed in the vehicle body 4. In this state, since the connector 20 is always located on the opposite side of the vehicle body locking portion 13 with the main body portion 12 interposed therebetween, the connector 20 does not contact the vehicle body 4. In addition, since the connector 20 is located between the clamp 10 and the wire harness trunk W-1, there is no contact with the external interference material.

In the second embodiment shown in FIGS. 6 and 7, the connector mounting direction of the connector mounting portion 14 'provided on the band clamp 10' is shifted by 90 degrees from the first embodiment.
That is, the connector mounting direction X2 is the same as the direction in which the band 11 protrudes. Since the other configuration is the same as that of the first embodiment, the same reference numerals are given and the description is omitted.

Since the connector mounting direction X2 is the same as the direction in which the band 11 protrudes, as shown in FIG. 7, the direction in which the branch line w-2 connected to the connector 20 is pulled out is perpendicular to the axial direction of the wire harness. Thus, when tightening with the band 11, the branch line W-2 drawn out from the connector 20 can be simultaneously tightened with the band 11 and held down.

When it is desired to change the direction of the connector 20 with respect to the wire harness W / H by 90 degrees, the clamp 10 of the first embodiment or the clamp 10 'of the second embodiment may be selected and used.

[0023]

As is clear from the above description, according to the present invention, since the connector mounting portion is provided on the clamp on the opposite side to the vehicle body locking portion, the connector mounting portion is always opposite to the vehicle body locking direction of the clamp. The connector is positioned in the direction, and when the wire harness is fixed to the vehicle body, the position of the connector does not vary. Also, since the connector mounting direction is regulated by the connector mounting part provided on the clamp,
By simply attaching the connector to the clamp, the direction of the connector can be regulated in a predetermined direction. As described above, the use of the clamp of the present invention has an advantage that the position and the direction of the connector do not vary as in the related art.

Furthermore, since the connector is fastened together with the wire harness by the band of the clamp in a state where the connector is sandwiched between the clamp and the wire harness, there is no possibility that the connector comes into contact with the external interference material. In addition, the connector can be attached to the wire harness by attaching the clamp to the wire harness, and the installation work to the wire harness, which was required twice in the past, can be done only once, greatly improving work efficiency. Can be.
