The laminate 2 is heated and fused to an insulating resin sheet of a flat harness in a state where the clamp 3 is attached to the laminate 2.

[0004]

As described above, since the clamp is fixed to only one flat harness and is locked to the vehicle body or the like, an additional flat harness is locked to the vehicle body using this clamp. I can't.

[0005] It is considered that an additional flat harness is fixed to the flat harness which is locked to the vehicle body via a clamp through an adhesive, but the adhesive deteriorates with age and has a problem in terms of permanence. There is.

The present invention has been made in view of the above-described problems, and in particular, a flat harness is added to a clamp which is attached to a flat harness and is locked to a vehicle body, so that the clamp can be attached to the clamp. That is the task. It is another object of the present invention to provide an arbitrary number of flat harnesses in a stacked state so that the flat harnesses can be attached to one clamp.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention locks a flat harness in which conductors arranged in parallel with a gap are laminated with an insulating resin sheet to a member to be locked such as a vehicle body. The flat harness is provided with mounting holes at both sides where the conductor is not located, and bent outwardly from the tips of both sides of the inverted U-shaped bridge portion. A locking seat is provided, a center portion of the locking seat is used as a pressing portion, and an end portion is used as an insertion portion, and locking wing portions are protruded from the center of the bridging portion on opposite sides to both side portions. A plastic clamp is provided, and the insertion portion of the locking seat of the clamp is bent and inserted into the pair of mounting holes of the flat harness, and the inserted insertion portion is locked on the back side of the flat harness. And the flat harness surface side Sandwiching by pressed by the pressing portion of the stop seat, it provides a clamp attachment structure of the flat harness that attach the clamp to the flat harness.

A plurality of flat harnesses are stacked on one clamp by inserting the insertion portion of the clamp through the mounting holes of a plurality of flat harnesses and locking the insertion portion on the back surface of the flat harness to be passed last. It is locked by. In this way, any number of flat harnesses can be attached to one clamp. Specifically, about 3 to 6 flat harnesses can be stacked and attached.

Attachment of the clamp to the flat harness
It is very easy to install by inserting the insertion portions of the locking seats on both sides of the clamp into the mounting holes pre-drilled in the flat harness and inserting and locking on the back side of the flat harness. I can do it. Further, since the flat harness is provided with the mounting hole, it serves as a mark of the mounting position to the clamp, and the mounting workability is good. In addition, since this mounting hole is formed in advance at the position where the clamp is mounted on the vehicle body, the dimensional management becomes easy.

In a state where the clamp that locks the flat harness is inserted into a locked member such as a vehicle body and locked, another flat harness is further inserted into the mounting hole of the flat harness. The part can be inserted and locked.

That is, even when the clamp is locked on the vehicle body and the flat harness is already routed, the insertion portion of the clamp inserted and locked into the mounting hole of the flat harness projects to the opposite side of the vehicle body. Therefore, additional wiring of the flat harness can be performed only by inserting the additional wire harness into the mounting hole of the clamp and locking it. Therefore, when an optional flat harness is added after the flat harness is routed to the vehicle body, it can be easily stacked using the clamp already locked to the vehicle body by stacking it on the already wired flat harness. Can be attached.

It is preferable that the insertion portion of the locking seat of the clamp protrudes forward and / or rearward in the longitudinal direction of the flat harness from the side of the bridge portion. By providing the insertion portion projecting in the front-rear length direction from the side edge of the bridge portion in this way, the clamp can be easily and securely attached to the flat harness.

The insertion portion protruding in the length direction is provided on both front and rear sides of one of the pair of locking seats, and is provided on one of the front and rear sides of the other locking seat. Preferably, it is provided. With this configuration, attachment of the clamp to the flat harness becomes easier.
