Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness that is wound around a wire harness and attached to the wire harness. The present invention relates to a wrapping band type wire harness clamp that arranges and holds a harness on a vehicle body / device.

[0002]

2. Description of the Related Art A clamp 1 for a winding band type wire harness (see FIG. 6) is a peripheral portion of a winding band 2 extending from one end of a band insertion locking portion 3 or a band insertion locking portion 3.
In addition, it has a basic structure in which a locking head 4 for locking a locking portion (not shown) such as a fitting hole of a vehicle body / device is erected, and the winding band 2 is wound around the wire of the wire harness 10. , Through the insertion locking hole 5 of the band insertion locking portion 3 and tightly locked and mounted, and locking the locking head 4 protruding from the outer periphery of the wound wire harness 10 to the vehicle body / device side Then, the wire harness 10 is arranged and held in the vehicle body or the like.

When the number of electric wires of the wire harness 10 around which the winding band 2 can be wound is very small, such as a few wires, the tightening by the rolled winding band 2 cannot be sufficiently performed, so that the tape 17 is attached to the wire harness 10. A method is adopted in which a large diameter is formed by winding the material in multiple layers, and the winding band 2 is wound around and attached to the large diameter portion.

[0004]

The conventional winding band type wire harness clamp 1 as described above, when the number of electric wires is extremely small, is very suitable for the tape winding work for making the small number of electric wires in a large diameter state. It takes a lot of time and effort, and the wire harness 1
Mounting on 0 becomes complicated and inefficient work.

Since the mounting of the wire harness 10 on the wire harness 10 is performed on a wire harness forming line for mass-producing the wire harness 10, the wire harness forming process is performed due to the complicated work of forming the large diameter portion by the tape winding. This is one of the factors that slows down the line processing line tact and reduces the wire harness molding productivity. The present invention provides a winding band type wire harness clamp that solves the above-mentioned drawbacks of the prior art.
