However, the conventional wire harness fixing band clip has the following problems. That is, since the conventional wire harness fixing band clip is made of plastic or nylon, the band is likely to slip with respect to the wire harness and the anchor may be displaced. Further, since the rigidity of the band is relatively high, there is a drawback that the band cannot sufficiently hold the wire harness when the number of electric wires is small and the harness diameter is small.

Further, since the anchor and the band are usually integrated with each other, when the shape of the anchor is changed, the band must be newly formed. In other words, when changing the shape of the anchor, even if the shape of the band is the same, a new mold is required,
The cost of the mold becomes high.

The present invention has been made in view of the above problems, and provides a wire harness fixing band clip capable of reliably fixing the wire harness and reducing the die cost when the shape is partially changed. The purpose is to

[0014]

DISCLOSURE OF THE INVENTION A wire harness fixing band clip according to the present invention is a wire harness fixing band clip for fixing a wire harness to a supporting member, and a band which has elasticity and holds the wire harness, and the band. An anchor that is fixed to the support member and that engages in a suitable position of the support member, and a band locking portion that is provided at one end of the band and that can lock the other end side of the band. It is characterized by being molded.

[0015]

In the present invention, the anchor is molded separately from the band, and the band is made of a stretchable material such as rubber. For this reason, when the wire harness is wound around the band, if the band is wound around the wire harness in a slightly stretched state and locked to the band locking portion, the wire harness can be reliably held by the stretching force of the band. This can prevent the band from slipping and the anchor position shifting.

Further, in the present invention, since the band is made of elastic material such as rubber, the band can be easily deformed and the wire harness can be securely held even when the wire harness diameter is small.

Further, since the anchor is formed separately from the band, when changing the shape of the anchor, for example, only the anchor forming die needs to be changed. It can be used as it is.

When a dish-shaped seal portion is provided in the anchor disposing portion of the band, the edge portion of the seal portion is moved by engaging the anchor with a hole provided at an appropriate position of the supporting member. Since the hole is closed by closely contacting with the wall surface of the support member around the hole, the waterproof property can be ensured. As a result, the work of disposing the waterproof packing on the base end portion of the anchor becomes unnecessary, and the workability is improved.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing a wire harness fixing band clip according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof. 3 is a sectional view taken along the line AA of FIG.

Band 1 is EPDM (ethylene-propylene)
terpolymer; a band-shaped member made of rubber such as ethylene-propylene trimer), and the locking portion 2 and the anchor 3 are fixed to one end of the band 1. Also,
The band 1 is provided with a dish-shaped seal portion 4 formed integrally with the band 1 so as to be aligned with the anchor 3. Further, the band 1 is provided with a plurality of holes 1a at predetermined intervals in the length direction.

The band locking portion 2 and the anchor 3 are members integrally formed by injection molding nylon or PP (polypropylene). The band locking portion 2 and the anchor 3 are fixed to the band 1 by insert molding when molding the band 1.

The locking portion 2 is a rod-shaped member having a bulged tip end, and locks the band 1 by engaging a hole 1a formed in the band 1. Also,
The anchor 3 is an anchor-shaped member including a shaft fixed to the band 1 and a pair of stopper portions that are laterally led out from the tip of the shaft. Is inserted into the hole.

FIG. 4 is a sectional view showing a method of using the band clip according to this embodiment.

First, the band 1 is wound around the wire harness 5 in a slightly stretched state, the hole 1a of the band 1 is engaged with the locking portion 2, and thus the band 1 is locked. Then, if necessary, the extra portion of the band 1 (that is, the portion on the tip side of the locking portion 2) is cut with scissors or the like. Then, the band clip is fixed to the support member by inserting the anchor 3 into a hole selectively provided in the support member. At this time, the edge portion of the seal portion 4 is brought into close contact with the wall surface around the hole provided in the support member, and the hole is liquid-tightly closed.

In the present embodiment, since the band 1 is made of rubber, it has elasticity and can securely hold the wire harness 5. As a result, it is possible to prevent the band clip from slipping in the circumferential direction of the wire harness 5 and causing the position of the anchor 3 to be displaced with respect to the wire harness 5.

Further, since the band 1 is made of rubber, even when the number of electric wires is small and the diameter of the wire harness is small, the band 1 is deformed and the wire harness 5a can be securely held, as shown in FIG. it can.

Further, since the anchor 3 is molded separately from the band 1, the mold for molding the band 1 can be used as it is even when the shape of the anchor 3 or the engaging portion 2 is changed. For example, even when the anchor has a shape as shown in FIG. 6, it is not necessary to change the mold for forming the band. In this case, the screw provided on the support member is used as it is to attach another component, and the band clip is fixed by screwing this screw into the hole provided in the anchor.

Furthermore, in this embodiment, when the anchor 3 is inserted into the hole of the support member (vehicle body or the like), the seal portion 4 is inserted.
The edge portion of the is closely contacted with the wall surface of the support member around the hole of the support member. As a result, the hole is liquid-tightly closed, and waterproofness can be ensured. Therefore, it is not necessary to dispose the waterproof packing on the base end portion of the anchor, and the workability is improved.

The shapes of the band and the locking portion are not limited to those in the above-described embodiment, but the band 11 may be locked by the buckle 12 as shown in FIG. 7, for example. In addition, as shown in FIGS.
5 is provided with sawtooth-shaped irregularities, and by these irregularities, the band 13,
The band 15 may be locked to the band locking portions 14 and 16.

[0031]

As described above, in the wire harness fixing band clip according to the present invention, the anchor is formed separately from the band, and since the band has elasticity, The wire harness can be reliably held, and the die cost for partially changing the shape can be reduced as compared with the related art.
