DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness forming protector for storing a wire bundle of a wire harness, attaching the wire bundle to a vehicle body / equipment, and adjusting and holding an arrangement posture of the wire harness. It is.

[0002]

2. Description of the Related Art A wire harness forming protector has a U-shaped groove shaped to receive and store a wire bundle of a wire harness. After the wire bundle is stored in the groove, the wire protector protects the wire bundle from jumping out. In addition, it has a common shape that covers the lid at the upper opening of the groove.

[0003]

However, since the U-shaped groove is made of a long resin and has a complicated shape which is bent into a three-dimensional shape in which a wire harness is to be disposed, the side wall of the groove is formed. Some of them are warped in the groove direction, which makes it difficult to store long and heavy wire harnesses, which is time-consuming and inefficient, and requires the step of locking and covering the lid. There is a drawback that the storing process is complicated and does not match the high productivity of recent mass production of wire harnesses.

The present invention provides a wire harness forming protector which solves the above-mentioned disadvantages of the prior art.

[0005]

A wire harness forming protector according to the present invention which solves the above technical problem is described in a wire harness forming protector comprising a U-shaped groove shaped to receive and store a wire bundle of a wire harness. A bottom plate of the groove body, which can be bent at the center of the groove width, and in a free state, a middle-high bending posture, and an upper opening of the groove body in an enlarged opening posture; and a main bottom plate. In the middle and high bending position of the section, the main bottom plate section and the sub-bottom plate section cooperate with each other by forming a hybrid arrangement of the sub-bottom plate sections bulging downward with the concave portion upward, and the main bottom plate section is stretched by a storage wire. A structure for forming a bottom plate of a U-shaped groove body ".

[0006] As an embodiment thereof, a holding piece of the storage wire is attached to the side wall of the U-shaped groove body, and the sub-bottom plate portion has a tray shape, a V-shape connected with a central hinge, or a curved band. A belt-shaped member or the like is used.

[0007]

In the wire harness forming protector of the present invention having the above-described structure, the bottom plate of the U-shaped groove is composed of a hybrid of the main bottom plate and the sub-bottom plate of the above-described structure. The middle and high bending posture of the main bottom plate portion in the free posture is secured. Therefore, the U-shaped groove body before the wire bundle storage, the groove body side wall continuously provided to the main bottom plate portion is inclined following the middle and high attitude, and presents a posture in which the upper opening is enlarged and opened,
It becomes very easy to store the wire bundle. When the weight of the bundle of stored electric wires is applied, the sub-bottom plate portion that swells downward and is in contact with the work table or the like is depressed and loses the above-mentioned tension. Fix,
The main and sub bottom plates cooperate to form a flat bottom plate, and the side walls of the groove also return to the normal position to form a normal U-shaped groove.

[0008] Since the weight of the wire bundle is always applied to the bottom plate portion, the main and sub bottom plate portions cannot be returned to the bent posture or the downward swelling posture, and the normal U-shaped groove body is stabilized. Furthermore, since the wire holding piece of the above aspect is retracted outward together with the side wall in the above-described enlarged opening posture of the groove body, it does not become an obstacle to wire bundle storage,
Since the stored electric wire bundle is pressed down in the normal U-shaped groove position, the lid is unnecessary.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. First, referring to FIG. 1 showing a first embodiment of the present invention, a pair of side plates 2 each having a shape for inserting and storing a wire bundle 1 of a wire harness.
The U-shaped grooved wire harness forming protector composed of the bottom plate 3 and the bottom plate 3 is a main bottom plate that can be bent into a middle and high shape via a hinge portion 4 extending in the longitudinal direction of the groove at the center of the groove width. Formed between the main bottom plate part 5 and the main bottom plate part 5 by a mixed arrangement of the sub-bottom plate parts 6 bulging downwardly of the groove and forming the upper surface as the concave part 7 in the middle and high positions of the main bottom plate part 5,
In the free state, the main bottom plate 5 assumes a middle-high bending posture by the tension of the sub-bottom plate 6 in the downwardly swelling posture, and the side plate 2 integrally connected to the side edge of the main bottom plate 5 is It has a structure in which the opening 8 of the U-shaped groove body is formed as an enlarged opening 10 that is greatly opened in an inclined posture.

The sub-bottom plate portion 6 forms an elastic band member bridged between the lower ends of the pair of side plates 2 via the hinge portion 4. The deployed length L of the band member is such that the side plate 2 is in a normal standing position. In the setting posture, when the shape of the normal U-shaped groove body is formed, the groove width B of the bottom plate 3 is set to be equal to the groove width B, and in the downward bulging posture,
The structure is such that the concave portion 7 is exposed above the groove body. In addition,
At the upper end of the side plate 2, a holding piece 9 for preventing the housed wire from jumping out is provided.
Are provided in a tongue shape.

Then, (see FIG. 1C), the main bottom plate 5
When the wire bundle 1 is accommodated from the enlarged opening 10 into the free-form wire harness forming protector in which the sub-bottom plate 6 bulges downward and the upper portion becomes the enlarged opening 10, At the same time, the sub-bottom plate portion 6 placed on and in contact with the work table 11 or the like is depressed to be in an extended state, and at the same time, the depression of the sub-bottom plate portion 6 is relaxed.
The main bottom plate portion 5 that has lost the holding tension in the middle and high positions is straightened,
The sub-bottom plates 5 and 6 cooperate to form a flat bottom plate 3 of a U-shaped groove, and the side plate 2 interlocked with the displacement of the main bottom plate 5 is erected with respect to the bottom plate 3. It becomes a normal U-shaped groove body, the wire bundle 1 is stored in the groove, and the wire bundle 1 is pressed down by the holding piece 9.

Next, another embodiment of the present invention will be described with reference to FIGS. That is, similarly to the above-mentioned embodiment, the bottom plate 3 of the hybrid arrangement of the main bottom plate portion 5 and the sub bottom plate portion 6 in FIG. And has a V-shape that can be folded at the center by a hinge portion 4 at the center in the groove. FIG. 3 shows a hinge 4 near the lower end of the side plate 2.
The main bottom plate 5 has a shape in which it is swelled downward in a middle-high position, and rises by elongating the main bottom plate 5 to form the bottom plate 3. ing.

Each of the above-described embodiments has the above-described operation, and facilitates the work of storing the wire bundle 1. In the case of the holding member 9, the conventional lid is unnecessary, the operation of locking the lid is omitted, and the wire storing process of the wire harness forming protector is simplified. further,
The one having the tray-shaped sub-bottom plate portion 6 has good stability to the work table 11 and facilitates further electric wire storage work. .

[0014]

As described above, the wire harness forming protector of the present invention has the effects of improving work efficiency of wire storage and improving efficiency, and improving the productivity of wire harness forming.
