DESCRIPTION OF THE PREFERRED EMBODIMENTS A wrapping band type wire harness clamp according to the present invention is implemented as follows.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, referring to FIG. 1 showing a first embodiment of the present invention, a winding band 2 to be wound around a single wire 10 of a wire harness is extended to a block-shaped band insertion locking portion 3. At the same time, the body
In the clamp 1 for a wrapping band type wire harness in which a locking head 4 for locking to a locking portion of a device is provided, a wire wrapping projection is provided between the band insertion locking portion 3 and the base end of the wrapping band 2. An electric wire hooking part 6 having a center 7 is provided on the winding space side of the winding band 2.

That is, the wire hooking portion 6 forms a plate having a length in the direction of extension of the wire 10 to be clamped, and has the wire winding protrusion 7 erected on the flexible substrate 8 as a main portion. And a pair of wire holding pieces 9A and 9B that are erected in a standing manner via the wire winding protrusion 7 and the wire insertion space 12 and are located on both sides in the winding direction of the winding band 2. The wire holding pieces 9A and 9B have an inverted L-shape in which the hook 11 at the upper end faces the wire winding projection 7, and the wire holding pieces 9A and 9B form a main part of the wire retaining mechanism.

Then, the electric wire 10 is inserted into the electric wire insertion space 12 and wrapped around the electric wire winding protrusion 7 once. Thereafter, the wrapping band 2 is rolled and inserted into the band insertion locking portion 3 to tighten. The substrate 8 is also rounded by the tightening force, and the wire holding pieces 9A and 9B are inclinedly displaced in the direction of the wire winding projections 7, and the hook pieces 11 at the upper end are joined to the upper ends of the wire winding projections 7 to form the wire insertion space 12 To prevent the electric wire 10 from coming off or jumping out.

Next, a second embodiment of the present invention will be described with reference to FIG. That is, in the band-type wire harness clamp 1 in which the locking head 4 is erected below the band insertion locking portion 3 in which the winding band 2 is extended, the substrate that touches the upper surface of the band insertion locking portion 3. An electric wire hooking portion 6 is provided, the main portion of which is a wire winding protrusion 7 erected at 8.

More specifically, the wire hooking portion 6 of this embodiment is
A pair of electric wire winding projections 7A and 7B that are erected on the opposite side via a band insertion space 13 into which the rounded band 2 can be loosely inserted.
The winding projections 7A and 7B and the band insertion space 13 constitute an electric wire retaining mechanism. Note that the wire winding projections 7A and 7B of this embodiment are provided with a hook L 11 that prevents the wire 10 from coming off from the upper end during a winding operation described later, and a hook L that extends in a direction opposite to the band insertion space 13. It is shaped like a letter.

Then (see FIG. 2 (B)), the electric wire 10 is entangled with the electric wire winding projections 7A and 7B and laid on the substrate 8, and thereafter, the electric wire hooking portion 6 is moved in the direction of the arrow C in FIG.
By rotating the wire 10 by 0 °, the wire 10 is wound around the wire winding protrusions 7A and 7B in an S shape, and in this state, the wrapping band 2 is inserted into the band insertion space 13 and When the wires 10 are inserted and locked and tightened, the tightening force presses down the wires 10 wound around the wire winding protrusions 7A and 7B and prevents them from falling off. You.

In the wire harness clamp 1 of the embodiment shown in FIGS. 1 and 2, the electric wire 10 is wound around the electric wire winding projection 7, and is held down by the electric wire retaining mechanism utilizing the tightening force of the winding band 2. Therefore, the electric wire 10 is mechanically accurately and sufficiently hooked to the wire harness clamp 1, and there is no possibility that the wire harness clamp 1 is displaced or detached from the electric wire 10, and the clamping performance is excellent. Stabilize. Then, the conventional complicated measures for increasing the diameter of the electric wire 10 become unnecessary.

The wire harness clamp 1 of the present invention is not limited to the above embodiment. For example, the wire winding projection 7 may be changed to another shape, or the wire winding projection 7 may be used.
The other wires that are not wound around the wire are gathered together with the wires 10 wound around the wire winding protrusions 7 and wound tightly with the winding band 2, or the pair of wire winding protrusions 7A and 7B
The electric wire 10 may be used by being manually wound around.

[0018]

As described above, the wrapping band type wire harness clamp of the present invention has a good clamping performance due to an improved fixing force to the wire even when the wire harness is mounted on a very small number of wires. To be stable. And, when mounting on a very small number of wires, the complicated wire thickening measures such as tape winding are unnecessary, so that the wire can be simply and accurately wound and tightened regardless of the number of wires. In addition to improving the workability of attaching to the wire harness, the improvement of the workability prevents a delay in the processing tact of the wire harness mass-production molding line, thereby improving the productivity of forming the wire harness.
