Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire support for supporting an electric wire to be laid during wiring work when assembling a wire harness.

[0002]

2. Description of the Related Art A wire harness including many electric wires is
Generally, it is assembled as follows. That is, a plurality of electric wire support tools are erected at predetermined positions on the wiring board, and the respective electric wires are wired along predetermined electric wire support tools. Such wiring work is called wiring work.
A wire bundle having a predetermined branch shape is formed by the wiring work, and a systemically wired wire harness is assembled.

By the way, at the time of the wiring work or after the wiring work, it is necessary to wind the binding tape around the required range of the formed electric wire bundle to bundle the electric wire bundle. Usually, the binding tape is wound around the outer periphery of the electric wire bundle in a spiral shape along the wiring direction of the electric wire bundle, and therefore, there have conventionally been the following problems. That is, since the electric wire support device is designed to receive the electric wire to be laid, the electric wire support device interferes when it is necessary to wind the tape in a range including the position received by the electric wire support device. The problem is that it becomes difficult to work.

In order to solve this problem, an electric wire holder called a so-called downer jig has been proposed. An electric wire holder called a downer jig has an electric wire receiving portion that receives an electric wire and can move up and down. That is,
When carrying out the wiring work, the electric wire receiving portion is arranged above, and when carrying out the tape winding work, it is arranged below. By arranging the wire receiving portion downward, the wire supporting tool is separated from the wire bundle so that the wire supporting tool does not interfere with the tape winding operation.

Further, in order to solve the above problems, an electric wire support tool called a bending jig has been proposed. An electric wire support tool called a folding jig can be displaced up and down between a state in which an electric wire receiving portion is erected with respect to a wiring plate and a state in which the electric wire receiving portion is laid down along the wiring plate. That is, when the tape winding operation is performed, the electric wire receiving portion is laid down to separate the electric wire support tool from the electric wire bundle so that the electric wire support tool does not interfere with the tape winding operation.

[0006]

However, in the downer jig, the wire receiving portion must be lowered once when the tape winding operation is performed, and further, the next wiring work is performed after the tape winding operation is completed. Therefore, there is a problem that the electric wire receiving portion has to be returned to the upper side again, and the operator has to perform a troublesome operation. This also applies to the bending jig. Further, since both jigs have complicated mechanisms, there is also a problem that the electric wire support becomes expensive.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an inexpensive electric wire support which can smoothly and quickly perform a tape winding operation on an electric wire bundle and a subsequent wiring operation without a troublesome operation. That is.

[0008]

In order to achieve the object of the present invention, an electric wire holder according to claim 1 has an electric wire receiving portion for receiving and supporting a bundle of electric wires to be laid, and an upper end of the electric wire receiving portion. A pillar that is connected and has an attachment portion to the wiring board formed at the lower end, and a deformation permitting means that is provided on the pillar and that allows deformation of the pillar in a recoverable state in the wiring direction of the wire bundle. It is characterized by having.

According to this structure, even if the position of the electric wire bundle supported by the electric wire support is included in the range in which it is necessary to wind the tape, the column is deformed during the tape winding operation, The electric wire receiving part is displaced so as to escape in the tape winding direction. As a result, the electric wire support does not interfere with the tape winding operation. Moreover,
Since the deformation of the support column is restored, when the tape winding operation is completed, the electric wire receiving portion automatically returns to the original position and supports the wired electric wire bundle again. Further, since a known means such as an elastic member can be adopted as a mechanism for restoring the deformation of the deformation permitting means, the deformation restoring mechanism can be simplified.

In order to achieve the object of the present invention, an electric wire support according to a second aspect is the electric wire support according to the first aspect, wherein the deformation permitting means includes an elastic member forming a part of the column. It is a feature. According to this configuration,
In addition to the effect of the invention according to the above-mentioned claim 1, the column can be configured by using the elastic member, and thus the structure of the entire electric wire support can be extremely simplified.

In order to achieve the object of the present invention, the wire support according to claim 3 is the wire support according to claim 1 or 2, wherein the wire receiving portion is formed in a substantially V shape. It is what According to this configuration, in addition to the effect of the invention according to claim 1 or 2, since the wire receiving portion is formed in a substantially V shape, when the deformation of the support is restored, the wire receiving portion is It is easy to return to the state of receiving the wire bundle.

[0012]

An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a main part perspective view showing a state in which a wire harness 4 is assembled using an assembly drawing board 3 having electric wire supports 1 and 2 according to an embodiment of the present invention. The assembly drawing board 3 includes the wiring board 5 and
A plurality of electric wire supports including the electric wire supports 1 and 2 described above. In addition, in FIG. 1, the wire support 1,
Although only two are shown in the figure, a larger number of electric wire supports are actually arranged.

The wiring plate 5 serves as a workbench when wiring the electric wires 6. Each electric wire support tool including the electric wire support tools 1 and 2 is erected on the wiring board 5. Each wire support is
The electric wires 6 to be laid on the wiring board 5 are received and supported, and are arranged at predetermined positions on the wiring board 5. Then, the electric wires 6 are wired along a predetermined electric wire support, and the key portions are bundled by the tape 8.
Thereby, the electric wire bundle 7 including the electric wires 6 is formed in a shape having a predetermined branch shape, and the wire harness 4 is assembled. Reference numeral 9 indicates a connector attached to the end of the predetermined electric wire 6.

A feature of this embodiment is that the electric wire support 1 can be elastically deformed in the direction of the white arrow in the figure. Then, by arranging the electric wire support 1 in a place where the tape 8 of the electric wire bundle 7 needs to be wound and supporting the electric wire bundle 7 by the electric wire support 1, the tape winding work can be performed easily and quickly. . FIG.
It is an expansion perspective view of the electric wire support tool 1. The electric wire support 1 will be described with reference to FIG. 2.

The electric wire support 1 has an electric wire receiving portion 10 for receiving and supporting an electric wire bundle 7 laid on the wiring board 5, and a column 11. The electric wire receiving portion 10 can be formed, for example, by forming a round bar into a substantially U-shape. The column 11 has a support rod portion 17 and a spring portion 18. The spring portion 18 is in a state of being inserted in the middle of the support rod portion 17. At the upper end of the support rod portion 17,
The electric wire receiver 10 is supported. A nut 13 having a fixing washer 12 is attached to the lower portion of the support rod portion 17. A male screw 14 is formed downward from the nut 13. The portion where the male screw 14 is formed is inserted into the mounting hole 15 provided in the wiring plate 5.
Then, by applying a fastening nut 16 to the male screw 14 from the lower surface side of the wiring plate 5, the electric wire support 1
Are fixed to the wiring board 5.

On the other hand, the spring portion 18 is formed in the intermediate portion of the support rod portion 17 as described above. That is, a part of the column 11 is formed by the spring portion 18. In this embodiment, a coil spring is used for the spring portion 18. Therefore, in the wire support 1, the wire receiving portion 10 can be elastically displaced in all directions in a plane parallel to the wiring plate 5.

The electric wire support 1 of the present embodiment is arranged at a place where the tape 8 needs to be wound on the wire bundle 7 that has been laid. The place where the tape 8 needs to be wound is, for example, a section including a branch point where another wire bundle 10 is branched from the wire bundle 7 (see FIG. 1). Then, the electric wires 6 are laid along the electric wire supports including the electric wire supports 1 and 2 to form the electric wire bundle 7. In this state, the electric wire support 1 supports the electric wire bundle 7,
The electric wire receiving portion 10 can be elastically displaced only in the wiring direction of the electric wire bundle 7 (the direction of the white arrow).

Next, the tape 8 is wound around the section. The tape 8 is wound in a spiral shape along the wiring direction of the wire bundle 7. In the present embodiment, the tape 8 is also wound around the branch portion 19 with the electric wire bundle 10 and the wiring direction of the electric wire bundle 10. At this time, the spring portion 18 bends and the electric wire receiving portion 10 moves in the wiring direction of the electric wire bundle 7 due to, for example, the hand of an operator winding the tape. That is, the wire receiving portion 10 is displaced so as to escape in the winding direction of the tape 8.

Therefore, when the tape 8 is wound around the wired electric wire bundle 7, even if the position where the electric wire supporting member 1 supports the electric wire bundle 7 is included in the range where the tape winding is necessary, By deforming the column 11 during the winding operation, the electric wire support 1 itself does not interfere with the tape winding operation. Further, since the column 11 is restored, when the tape winding operation is completed, the electric wire receiving portion 10 automatically returns to the original position and supports the electric wire bundle 7 again. As a result, the tape winding work and the subsequent wiring work can be performed smoothly, quickly and easily. In addition, in this embodiment, since the coil spring is used to allow the elastic deformation of the column 11, the entire structure of the wire support tool 1 can be extremely simplified, and the wire support tool 1 can be manufactured at low cost. can do.

Further, the present invention is not limited to the above-mentioned one embodiment, and various modifications as described below can be added. First, referring to FIG. 2, the spring portion 18 is not limited to the intermediate portion of the support rod portion 17, and the upper portion of the support rod portion 17 from the nut 13 may be formed by a coil spring. Thereby, the wire receiving portion 10 can be displaced more smoothly, and the tape winding operation can be further facilitated.

In addition, as shown in FIG.
Can be formed in a substantially V shape. As a result, the electric wire receiving portion 20 gradually expands upward in a state where the column 11 is not deformed. Therefore, when the support 11 is restored, the wire receiving portion 20 can reliably receive the wire bundle 7, and the subsequent wiring work can be carried out more smoothly.

Further, as shown in FIG. 4, the spring portion 18 may be constructed by using a pair of coil springs 21 and 22. In this case, the pair of coil springs 21 and 22
Can be connected using a pair of upper and lower plate members 23 and 24. With this configuration, it is possible to suppress wobbling of the wire receiving portion 10 when supporting the wire bundle 7.
Further, as shown in FIG. 5, the spring portion 18 may be formed of a leaf spring. With this configuration, it is possible to prevent the electric wire receiving portion 10 from displacing in a direction intersecting with the wiring direction of the electric wire bundle 7 while supporting the electric wire bundle 7, and to reliably move the electric wire bundle 7. Can be supported. Other,
Various design changes can be made within the scope of the present invention.

[0023]

According to the first aspect of the invention, when the binding tape is wound around the laid wire bundle, the wire supporting member that interferes with the tape winding operation can be separated from the wire bundle by the deformation of the column. You can do it, and after finishing the tape winding work,
The bundle of wires can be supported again by the restoration of the pillar. That is, it is possible to smoothly perform the tape winding operation on the wire bundle that has been laid, and it is also possible to quickly perform the subsequent wiring work. In addition, it is easy to simplify the structure, and it is possible to provide the electric wire support at low cost.

According to the invention of claim 2, the same effect as that of the invention of claim 1 can be obtained. In addition, since the column is made of an elastic member and the entire structure can be made extremely simple, there is an advantage that the wire support can be provided at a very low cost. According to the third aspect of the invention, the same effects as those of the first or second aspect of the invention can be obtained. In addition, when the deformation of the column is restored, the wire bundle can be reliably received by the wire receiving portion. In other words, when the stanchions are restored, the wires that make up the wire bundle can be prevented from coming off the wire receiving part, and this makes it difficult to return the wires that have come off the wire receiving part to the wire receiving part again. Can be eliminated. Therefore,
A smoother and faster tape winding operation and subsequent wiring operation can be performed.
