Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire bundle holder, and more particularly, to a wire rod capable of bundling and fixing a long wire bundle such as a wire harness at a predetermined position on a panel of a vehicle body or an electric device. The present invention relates to a bundle holder.

[0002]

2. Description of the Related Art In general, it is known to use a holder for fixing a wire harness or the like to a predetermined position of a panel of a vehicle body, an electric device, or the like. An example described in Japanese Patent Application Laid-Open Publication No. H10-209,000 is known, and is shown in FIG. 4 (hereinafter, this conventional example is referred to as a first conventional example).

[0003] In FIG. 4A, reference numeral 1 denotes a binding band, which is wound around a wire harness and has a band member 2 having an engaging hole 2a formed in an extending direction, a body member, and the like. A non-return locking member 3 inserted into an opening formed in a panel of an electronic device or the like to be retained and engaged with the non-return locking member 3. A deformable blade member 4 having an elastic force and a member formed at the tip of the band member 2 and engaged with the engagement hole 2a of the band member 2 when the tip of the band member 2 is inserted. And a lock member 5 having a mating piece 5a.

In such a binding band 1, FIG.
As shown in (b), the band member 2 is attached to the wire harness 6.
The wire harness 6 is wound by inserting the distal end of the band member 2 into the lock member 5 and engaging the engaging hole 2a with the engaging piece 5a when the diameter substantially matches the diameter of the wire harness 6. It can be held firmly. Other binding bands include those described in Japanese Utility Model Laid-Open No. 1-158811, and are shown in FIG. 5 (hereinafter, this conventional example is referred to as a second conventional example).

In FIG. 5, a holder 11 has an annular gripping member 12 having a high hardness and a gripping member 13 connected to the gripping member 12, and when the wire harness is gripped by the gripping member 12, The wire harness is firmly held by engaging the engagement protrusion 13a formed on the gripping member 13 with the engagement hole 12a formed on the wire harness.

As another binding band, there is one described in Japanese Utility Model Laid-Open Publication No. 1-146723, which is shown in FIG. 6 (hereinafter, this conventional example is referred to as a third conventional example). In FIG. 6, reference numeral 21 denotes a holding tool for holding a corrugated pipe 22 for protecting the wire harness, and the holding tool 21 is a pair of holding members connected via a hinge 23.
24, 25, formed on the ends of the gripping members 24, 25, coupling members 26, 27 that engage with each other to join the gripping members 24, 25, and are formed on the inner peripheral surfaces of the gripping members 24, 25, An engaging piece 25a (the gripping member 24 side is not shown) which engages with the concave portion of the corrugated pipe 22. When the corrugated pipe 22 is gripped by the gripping members 24, 25, Tube 22
After fitting into the concave portions, the engaging portions 26 and 27 are engaged to hold the wire harness 28 via the corrugated tube 22.

[0007]

However, according to the first conventional example, when attaching the binding band 1 to the wire harness 6, the distal end of the band member 2 is inserted into the lock member 5. Since the work was required, the mounting work became troublesome (this insertion work is like using a needle to pass a thread through a needle hole).

Further, after the band member 2 is inserted through the lock portion 5, an extra band member (indicated by an imaginary line in FIG. 4B) must be cut, so that extra work is required. In addition, there is a problem that chips are generated. According to the second conventional example, when the wire harness is gripped by the gripping member 12, the engagement protrusion formed on the gripping member 13 is formed in the engagement hole 12a formed in the gripping member 12. Because the wire harness was held by engaging 13a,
There is a problem that it can cope only with a wire harness having a fixed diameter and cannot be attached to a wire harness having a different diameter. In addition, the engagement protrusion 13a and the engagement hole 12
There was also a problem that the engagement of a was weak and the wire harness could not be held firmly.

Further, the third conventional example has a problem that it cannot be applied to a corrugated pipe 22 having a fixed diameter, and cannot be directly attached to a wire harness. Therefore, an object of the present invention is to provide a wire bundle holder which can be easily attached to a wire bundle having a wide diameter without generating chips.

[0010]

According to the first aspect of the present invention,
In order to solve the above-mentioned problems, a wire bundle holder for holding a wire bundle and attaching the wire bundle to a mating member is provided. The holder includes a base, and protrudes from a surface of the base and is attached to the mating member. A first band member that protrudes from one side surface of the base, extends in a predetermined direction, and has a first uneven portion continuously formed on an outer peripheral surface thereof and is bent at a predetermined radius of curvature; A second uneven portion protruding from the other side surface and extending in a predetermined direction, and a second uneven portion engaging with the first uneven portion is continuously formed on an inner peripheral surface, and is bent at the same radius of curvature as the first band member. A band member, an engaging uneven portion continuously formed on the inner peripheral surface of the first band member, and an engaging portion formed on the back surface of the base portion and capable of engaging with the engaging uneven portion. And the first band member is connected to one side surface of the base via a hinge. It continued, and when holding the wire bundle by said band member is characterized in that so as to move the first band member along the inner peripheral surface of the second band member.

In this case, when the wire bundle is held by the first and second band members, the first band member is moved along the inner peripheral surface of the second band member using the second band member as a guide. The engaging uneven portion of the first band member is guided to the engaging portion, and the engaging uneven portion and the engaging portion are engaged. At this time, the first uneven portion and the second uneven portion also engage. For this reason,
The first band member and the second band member can be removed with one touch.
The first band member and the second band member can be firmly engaged with each other to hold the wire bundle firmly. Further, since it is not necessary to cut off an unnecessary portion as in the related art, it is possible to prevent unnecessary work and to prevent generation of chips.
As a result, the workability of attaching the holder can be greatly improved.

Further, the first band member is moved along the inner peripheral surface of the second band member so that the engaging concave and convex portion is engaged with the engaging portion at a position corresponding to the size of the wire bundle.
The holder can be attached to a wide wire bundle. In order to solve the above-mentioned problems, the invention according to claim 2 is based on claim 1.
In the invention described in the above, a cover for covering the engaging portion is provided on the back surface of the base.

In this case, the wire bundle held on the inner peripheral surfaces of the first band member and the second band member is prevented from coming into contact with the engaging portion, and the first band member is moved along the second band member. It can be reliably guided to the engaging portion.
