DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire support used when assembling a wire harness.

[0002]

2. Description of the Related Art Generally, a wire harness for an automobile is
It includes a number of electric wires as its components, and these electric wires are bundled at important points by tape winding or the like, and are assembled so as to have a branch shape designed in advance. When assembling a wire harness, what is conventionally called an assembly drawing board is used. FIG.
It is the principal part perspective view which showed the state which is performing the assembly work of the wire harness WH using the assembly drawing board A. With reference to the figure, the assembly drawing board A is configured so that the wiring board 1 serving as a work table, and the wire harness after assembly are designed in advance, when performing the assembly work of the wire harness WH. ,
And an electric wire support 2 for receiving each electric wire. The wire supports 2 are erected at predetermined plural positions on the wiring board 1. In the drawings, reference numeral E indicates the above-described electric wire, and reference numeral C indicates a connector attached to an end of the electric wire E.

As shown in the drawing, each electric wire E is laid along a plurality of electric wire supports 2. That is, each electric wire E is received by each electric wire support 2 having a U-shaped upper portion, and in some cases, is bent in a predetermined direction to be wired on the wiring board 1. As the wiring work progresses, a wire bundle in a pre-designed form is formed on the wiring board 1. In the wiring work, in order to temporarily fix the branch portion J1 of the wire bundle, an operation of appropriately winding the tape T around the branch portion J1 is performed.

[0004] In performing the wiring work, there have conventionally been the following requirements. More specifically, since the upper portion of the electric wire support 2 has a U-shape, the electric wire E1 may protrude from the electric wire support 2a during the wiring work as shown in the drawing. This is particularly remarkable in a portion where the electric wire E is bent. In such a case, the worker
During the wiring work, the protruding wire E1 must be hooked again on the wire support 2a, which is very troublesome. If the branch portion J1 of the wire bundle is temporarily fixed without noticing that the wire E1 protrudes from the wire support 2a, the protruded wire E1 may not be hooked on the wire support 2a. Therefore, the tape T may not be wound around the branch portion J2 where the wire E1 protrudes, and may not be temporarily fixed.
As a result, the operator is forced to perform an extremely troublesome operation of removing the tape T of the branch portion J1 temporarily fixed and then processing the protruding wire E1.

For this reason, the electric wire support 2 has the electric wire E
There is a demand to have a holding function of holding the electric wire E received so as not to protrude. When the electric wire E is bent and wired, a wiring path difference due to the bending occurs. However, it is preferable that the wiring be performed so that the wiring path difference is as small as possible. That is, it is preferable that the cross-sectional shape of the wire bundle formed by the plurality of wired wires E is close to a circle.

[0006] Therefore, there is a demand for the wire support 2 to have a function of bundling and receiving the wire bundle in a substantially circular shape. In order to meet the above demand, a converging jig disclosed in Japanese Utility Model Laid-Open No. 5-17853 has been conventionally provided. FIG. 5 is a perspective view of the converging jig. As shown in the figure, the converging jig has a V-shaped flange portion 3 expanding outward and a substantially circular ring-shaped main body portion 4 continuously formed therewith. Main unit 4
Is divided into two, and the movable ring piece 4a is rotatably connected to the fixed ring piece 4b. The movable ring piece 4a can rotate outward (in the direction of the arrow) from a position where the main body 4 is formed in a ring shape (a position shown in the figure) to a position where the held wire bundle is taken out. I have.
The reference symbol SP is a spring that toggles on the rotation of the movable ring piece 4a. In this converging jig, the electric wire E can be inserted into the main body 4 from the opening formed by the V-shaped flange 3. On the other hand, the wire E once inserted can be prevented from easily protruding outside the main body 4.

In order to meet the above demand, a wiring jig disclosed in Japanese Patent Application Laid-Open No. Hei 6-223644 has been conventionally provided. In this wiring jig, a substantially circular wire hook portion is formed as a whole, and a gap for wire insertion is formed at the upper end of the wire hook portion. This allows
The cross-sectional shape of the electric wire bundle formed of a plurality of electric wires hung on the electric wire hooking portion is closer to a circle as compared with the case where the electric wire bundle is received by the conventional electric wire support 2.

[0008]

However, in the above-mentioned converging jig, since the gap is formed in the flange portion 3, the main body portion 4 cannot be completely annular.
For this reason, the wired electric wire E may protrude from the main body 4 in some cases. In particular, in a state where a large number of electric wires E are received by the main body 4 due to the progress of the wiring work, the electric wires E are more likely to protrude. The same can be said for the wiring jig. For this reason, it is difficult for conventional converging jigs and wiring jigs to receive the wire bundle so that the cross-sectional shape becomes substantially circular. That is, the conventional converging jig and the wiring jig cannot satisfy the above-mentioned requirements.

More recently, wire harnesses for automobiles have increased in the number of electric wires as components and have become more complicated after assembly, so that wire harnesses have been successfully applied to the limited mounting space of the vehicle body. I have to install it. For this reason, in the assembling stage, there is a case where it is necessary to fix the shape by bending or bending three-dimensionally in advance in accordance with the mounting space. In such a case, conventionally, an accessory called a forming protector for correcting and fixing the shape of the wire bundle is attached to the wire bundle.

[0010] However, by mounting this molded protector, the external dimensions of the wire bundle become large, and it may be rather difficult to mount the wire bundle in a limited space of the vehicle body. In addition, using a molded protector
The number of parts and the number of man-hours for assembling the wire harness have increased, and the cost has risen. That is, it is desirable to eliminate the forming protector from the components of the wire harness.

On the other hand, in order to fix the shape of the electric wire bundle without using a molding protector, it is necessary to surely keep the cross-sectional shape of the electric wire bundle substantially circular in a state where each electric wire E is laid. . Because, when the wires are bundled in a substantially circular shape at the time of wiring, the wires can be tightly tape-wrapped without breaking the wires E, and the wires are bundled in a substantially circular shape. This is because by strongly winding the tape around the wire bundle, the wire bundle can be fixed in a curved or bent state.

As described above, recently, there has been a strong demand that the bundle of electric wires be surely bundled into a substantially circular shape in a state of being wired. Accordingly, an object of the present invention is to provide an electric wire support that can prevent an electric wire from protruding and reliably bundle and catch an electric wire bundle in a substantially circular shape in order to satisfy the above requirements.

[0013]

Means and operation for solving the problems] 請 Motomeko 1, wherein
The invention has a wire receiving portion that receives and supports a bundle of wires laid along a wiring board, and a support column that supports the wire receiving portion at an upper end and has a lower end attached to the wiring board. In the wire support for assembling a wire harness having the wire receiving portion, a first curved member having a substantially semi-arc shape and provided at an upper end of a column, and one end portion provided at one end portion of the first curved member. The other end is the first
A first posture in which a substantially circular surrounding space surrounding the wire bundle is formed in cooperation with the first bending member by contacting the other end of the bending member, A second bending member that can be displaced between a second position that opens the surrounding space by separating from the other end of the member ;
The second bending member is extended at one end thereof, and the second bending member has a second weight due to its own weight.
And an extending member that constantly urges the curved member to the first posture side.
Characterized by having a wire harness assembly
It is a wire support.

According to this configuration, the second bending member is provided with the first bending member.
When the first bending member and the second bending member are displaced to each other, the first bending member and the second bending member come into contact with each other, so that a surrounding space that is a substantially circular closed space can be formed. In other words, when wires are laid, the first and second bending members can completely surround each of the wires accommodated in the surrounding space. Therefore, it is possible to prevent the wires in the surrounding section from protruding outside. Moreover, since the surrounding space forms a substantially circular closed space, when receiving the electric wires, the cross-sectional shape of the electric wire bundle constituted by the electric wires can be formed to be approximately circular.

On the other hand, after completion of the wiring work, the surrounding space can be opened by displacing the second bending member to the second posture, whereby the wire bundle can be taken out from the surrounding space. Moreover, since the first and second bending members are both formed in a substantially semicircular arc shape, when the second bending member is displaced to the second posture, the substantially circular surrounding space has a substantially diameter portion. Divides into two. Therefore, by displacing the second bending member, it is possible to form an opening having a diameter larger than the diameter of the surrounding space, whereby the wire bundle in the surrounding space can be easily taken out.

[0016]

[0017] pressurized forte, the second bending member, when in the first posture, by the weight of the extended members at all times its posture is maintained. In other words, the second bending member is urged to return to the first posture side when it is displaced to the second posture side, and the first bending member and the second bending member are normally An abutting space is formed, and a surrounding space that is a substantially circular closed space is formed. Therefore, even if the second bending member attempts to displace to the second posture side during the wiring work, this is suppressed, and as a result, during the wiring work, the second bending member opens and the electric wire in the surrounding section is opened. Can be effectively prevented from protruding outside.

In addition, since the second bending member is always in contact with the first bending member at all times, if the electric wire to be laid is pushed from between the two bending members, the second bending member is pressed. The bending member is slightly displaced to the second posture side, and the electric wire can be easily accommodated in the surrounding space. On the other hand, after the completion of the wiring work, if the electric wire bundle formed in the surrounding space is grasped by hand and pulled, the second bundle is pushed out by the electric wire bundle.
Is displaced rotationally to the second posture. This allows
The wire bundle can be easily taken out of the surrounding space, and after taking out the wire bundle, the second bending member is rotationally displaced to the first posture by the weight of the extension member.

[0019] 請 Motomeko 2 wire support for a wire harness assembly according to, in the wire support of wire harness assembly of claim 1 Symbol placement, the second bending member second position from the first position An elastic member is provided which pulls the extending member which rotates with the movement of the second bending member in the counter-rotating direction when the second bending member moves to the side.

According to this configuration, the same operation as the first aspect of the invention is achieved. In addition, when the second bending member is rotationally displaced toward the second posture, the elastic member pulls the extension member, thereby applying an elastic force to the second bending member so as to be pulled back in the anti-rotational direction. Is done. Therefore, it is possible to strongly suppress the displacement of the second bending member to the second posture.

[0021] 請 Motomeko wire support for a wire harness assembly according to 3, in the wire support of wire harness assembly of claim 2, wherein said elastic member is in a state of connecting the extended members and struts The elastic member and at least one of the extending member and the support are connected to be movable by a predetermined amount.

According to this configuration, the same operation as that of the invention according to claim 2 is exerted. In addition, since the elastic member is interposed between the extending member and the column with so-called play, even if the elastic member is provided, the second bending member always extends. Due to the weight of the member, it is in a state of only contacting the first bending member. Therefore, if the elastic member is provided in a state where there is no play, the second bending member is always elastically urged to the first bending member by the elastic force of the elastic member, and the electric wire to be laid is cut. Although it is difficult to push in between the two curved members, such an inconvenience does not occur in the invention according to the present invention.

[0023] 請 Motomeko wire support for a wire harness assembly according to 4, in the wire support of wire harness assembly according to any one of claims 1 to 3, the other end portion of the first bending member The other end of the second bending member is bent in a direction opposite to the bending direction of the first bending member,
The second bending member is bent in a direction opposite to the bending direction, and when the second bending member is in the first posture, the other end portions of the two bending members open outward in a pair. The electric wire receiving guide part is constituted.

According to this configuration, the same operation as the invention according to any one of the first to third aspects is achieved. In addition, since the wire receiving guide has a so-called funnel shape from the outside to the inside with respect to the surrounding space, the wire to be received is pushed from between the first and second bending members. And the electric wire receiving and guiding portion allows the electric wire to be easily guided and accommodated in the surrounding space.

[0025] 請 Motomeko 5 wire support for a wire harness assembly according to, in the wire support of wire harness assembly according to any one of claims 1 to 4, the other end of the first bending member When the second bending member turns to the first posture side, a contact surface portion with which one end of the second bending member comes into contact is formed.

According to this configuration, the same operation as the invention according to any one of the first to fourth aspects is achieved. In addition, the second
When the second bending member is displaced to the first posture, the other end of the second bending member surely comes into contact with the contact surface of the contact surface portion. Therefore, a substantially circular surrounding space can be reliably formed. Wire support for a wire harness assembly according to 請 Motomeko 6 is the wire support of wire harness assembly according to any one of claims 1 to 5, the other end portion of the first bending member, the surround At a predetermined portion inside the space, a first curved surface curved in a direction opposite to a bending direction of the first bending member is formed, and at a second end of the second bending member,
A second curved surface that is curved in a direction opposite to a bending direction of the second bending member is formed at a predetermined portion inside the surrounding space, and the second bending member is displaced to the first posture. In this state, the ends of the two curved surfaces abut each other, and the two curved surfaces constitute a funnel-shaped surface portion in which a part of the inner peripheral surface that defines the surrounding space gradually narrows outward in the radial direction of the surrounding space. It is characterized by being performed.

According to this configuration, the same operation as the invention according to any one of the first to fifth aspects is achieved. In addition, when the wiring operation is completed, when the formed wire bundle is pulled up, the wire bundle can be more easily taken out of the surrounding space while being guided by the funnel-shaped surface portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view of a wire support BR according to an embodiment of the present invention. The wire support BR is included in an assembly drawing board A used when assembling a wire harness, and is a wiring board 10 serving as a working table when wiring the wires E.
It is fixed at a predetermined upper position. Although only a single wire support BR is shown in FIG. 1, a plurality of wire supports BR are erected on the wiring board 10 in practice. The plurality of electric wires E included in the wire harness are:
Wires are laid along the plurality of wire supports BR arranged at these predetermined positions, and assembled in a predesigned form.

The electric wire support BR has an electric wire receiving portion 20 for receiving and supporting each electric wire E laid along the wiring board 10.
And a column 30 for supporting the wire receiving portion 20 at the upper end. Although only one wire E is shown in FIG. 1, the wire receiving portion 20 receives a wire bundle including a plurality of wires E as the wiring operation progresses. The support 30 is, for example, a round bar-shaped member. A nut 31 on which a fixing washer 31a is formed is attached to a lower portion of the column 30. This nut 3
A male screw 32 is formed from 1 to the lower end.
The portion where the male screw 32 is formed is inserted through the mounting hole 11 provided in the wiring board 10. And this male screw 3
The wire support BR is fixed to the wiring board 10 by applying a fastening nut N to the two portions from the lower surface side of the wiring board 10.

One of the features of this embodiment lies in the structure of the electric wire receiving portion 20. The electric wire receiving portion 20 has a fixed curved member 21 having a substantially semicircular arc shape and rotates with respect thereto. And a movable bending member 22 having a substantially semicircular arc shape.
A substantially circular surrounding space 40 in which the electric wire E is accommodated in a state where the electric wire E is surrounded is defined. The movable bending member 22 includes the movable bending member 22.
Lever 2 for always rotating to the fixed bending member 21 side
When the movable bending member 22 is rotationally displaced in a direction in which the movable bending member 22 opens (in the direction indicated by a white arrow), the movable bending member 22 has a force corresponding to the displacement. Is connected to an endless rubber band 24 that pulls the rubber band 24 in the direction opposite to the displacement direction.

Hereinafter, the electric wire receiving portion 20 will be described in detail. The electric wire receiving portion 20 includes a fixed bending member 21, a movable bending member 22, a lever 23, and a rubber band 24. The fixed bending member 21 includes a pair of substantially semicircular plate members 21a. The pair of plate members 21a are arranged to face each other with a gap d therebetween. Fixed curved member 2
One end 21e side of 1 is fixed to the upper end of the column 30. A spacer S is provided on the other end 21b of the fixed bending member 21.
Is interposed. That is, the spacer S having the same thickness as the gap d is inserted between the pair of plate members 21a, and the pair of plate members 21a and the spacer S are fixed to each other. Further, the other end 21 b of the fixed bending member 21 is smoothly curved in a direction opposite to the bending direction of the fixed bending member 21.

The movable bending member 22 is a single plate member having a substantially semicircular arc shape, similarly to the fixed bending member 21. One end of the movable bending member 22 is sandwiched between one end 21e of the fixed bending member 21 formed of a pair of plate members 21a, and is rotatably connected to the fixed bending member 21 via the pin P. The movable bending member 22 is rotatable and displaceable between a first posture and a second posture described below. To elaborate further,
The bending direction of the movable bending member 22 is opposite to the bending direction of the fixed bending member 21. That is, the fixed bending member 21 and the movable bending member 22 are in a state where the ring member is divided into two equal parts, so to speak, the other ends 21 b and 21 b of the two 21 and 22.
The rings 22b abut each other to form a ring (first posture) and separate from each other (the other end 22b of the movable bending member 22 becomes the other end 21b of the fixed member 21).
Away from the ring), the ring is divided into two parts along a substantially diameter (second posture). The inside of the ring formed when the movable bending member 22 is displaced to the first position is the surrounding space 4 in which the wired electric wire E is accommodated.
0.

That is, in the present embodiment, the movable bending member 22
Is displaced to the second position, the surrounding space 40 is opened, and its opening diameter is set to be larger than the diameter of the surrounding space 40. Further, the other end 21b of the fixed bending member 21 has a plate shape whose thickness dimension is larger than the thickness of the movable bending member 22 due to the interposition of the spacer S. The other end portion 22b can reliably contact the other end portion 21b of the fixed bending member 21 when rotated to the first posture side.

The other end 22b of the movable bending member 22
Are smoothly curved in the direction opposite to the bending direction of the movable bending member 22. Thereby, when the fixed bending member 21 and the movable bending member 22 come into contact with each other, the two members 21 and 22
The other end portions 21b and 22b are separated from each other,
That is, the state is gradually expanded outward from the surrounding space 40. The gradually expanded portion formed by the other end portions 21b and 22b constitutes an electric wire receiving and guiding portion 50. By guiding the electric wire E laid by the electric wire receiving guide 50, the electric wire E can be easily surrounded by the surrounding space 40.
It can be accommodated inside.

On the other hand, the fixed bending member 21 and the movable bending member 2
2 contact each other, the other end 21 of both 21 and 22
The funnel-shaped surface portion 60 is formed on the side of the surrounding space 40 by the b and 22b. The funnel-shaped surface portion 60 is formed by a curved surface 21 on the side of the surrounding space 40 of the other end portion 21 b of the fixed curved member 21.
c and the surrounding space 4 of the other end portion 22 b of the movable bending member 22.
And a curved surface 22c on the zero side. That is,
As shown in the drawing, a part of the inner peripheral surface that defines the surrounding space 40 is gradually narrowed outward in the radial direction by the funnel-shaped surface portion 60. Thereby, the surrounding space 4
The wire bundle can be easily taken out from the inside.

The lever 23 is an L-shaped plate member, and extends at one end of the movable bending member 22. Specifically, it is formed integrally with the movable bending member 22. The lever 23 is arranged so as to extend outward from the gap d formed on the fixed bending member 21 side. The lever 23 rotates counterclockwise in the figure around the pin P by its own weight. For more information,
The rotational moment about the pin P due to its own weight of the lever 23 is larger than the rotational moment about the pin P due to its own weight of the movable bending member 22. It rotates in a counterclockwise direction. Therefore, the movable bending member 22 always rotates in the direction in which it contacts the fixed bending member 21 (the direction in which the surrounding space 40 is partitioned), and is in contact with the fixed bending member 21.

Further, a rubber band 2 is attached to the end 23a.
4 are connected. This rubber band 24 is
It is also connected to the side. Therefore, the movable bending member 22 rotates in the direction of the white arrow, and the lever 23
Is displaced, the lever 23 is pulled in a direction opposite to the displacement direction by an elastic force caused by the expansion of the rubber band 24. In this embodiment, the rubber band 24 is attached with some play. Accordingly, the rubber band 24 is
Is in a first position, that is, in a state where it is in contact with the fixed bending member 21 (the state shown in the figure), it is in a steady state, and is set so as not to exert any force on the lever 23.

That is, the lever 23 is always in the state shown in FIG.
When the movable bending member 22 is rotated by a predetermined amount or more in the direction to open the surrounding space 40, that is, the lever 23 Only when the lever 2 is displaced in the counterclockwise direction in the figure, the lever 2
3 is pulled back. Therefore, the movable bending member 22 is in a state where the rotation from the first posture to the second posture side is suppressed, and the suppressing force is the movable bending member 2.
2 is given by the elastic force corresponding to the rotation angle.

Next, the operation and effect of this embodiment will be described. Since the other end portions 21b and 22b of the fixed bending member 21 and the movable bending member 22 are in contact with each other, both 21 and 22 are fixed.
No gap is formed between them. Therefore, when the electric wires E are laid, each electric wire E accommodated in the surrounding space 40 is
Is completely surrounded by the fixed bending member 21 and the movable bending member 22. Moreover, even if the movable bending member 22 attempts to displace to the second posture side, this displacement is suppressed by the biasing force of the lever 23 due to its own weight. Can be prevented from protruding outside. as a result,
Correction work due to dropping of the electric wire E once received by the electric wire receiving portion 20 can be eliminated, and wiring work can be performed smoothly.

In addition, at all times (when the movable bending member 22 is in the first position), the movable bending member 22 is only in contact with the fixed bending member 21. If the electric wire E is pushed downward from between the two bending members 21 and 22, the movable bending member 22 is slightly displaced to the second posture side while being pushed away by the electric wire E, and the electric wire E is easily moved. Can be accommodated in the surrounding space 40. That is, although the surrounding space 40 is always a completely closed space, the electric wire E can be easily accommodated in the surrounding space 40 during the wiring work.

In the present embodiment, the rubber band 24 is provided, and the elastic bending force of the rubber band 24 causes the movable bending member 22 to be opened to be pulled back in the closing direction. Thus, the surrounding space 40 can be effectively prevented from being opened, and the electric wires E can be reliably prevented from protruding from the surrounding space 40 to the outside. In particular, since the rubber band 24 is provided with play, even if the movable bending member 22 is slightly displaced to the second posture side when the electric wire E is pushed in, the elastic force of the rubber band 24 is movable. It does not add to the member 22. Therefore, the work of housing the electric wire E in the surrounding space 40 does not become difficult.

Since the surrounding space 40 has a substantially circular shape, the electric wire bundle formed by the received electric wires E is formed so that the cross-sectional shape thereof is substantially circular. Therefore, in the wiring work, the wiring path difference between the electric wires E can be reduced. As a result, the accuracy as an assembly can be improved, and the completeness and reliability of the wire harness can be improved.

Further, since the surrounding space 40 is a completely closed space, the sectional shape of the wire bundle to be received can be surely formed to be substantially circular. Therefore, after the wiring work, the wire bundle can be strongly wound with the tape without disturbing the wire bundle. Accordingly, the wire bundle can be fixed by being bent or bent into a predetermined shape, and a molding protector for fixing the shape can be eliminated from the components of the wire harness.

Referring to FIG. 2, after completion of the wiring work, if the wire bundle WE formed in the surrounding space 40 is grasped by hand and pulled upward, the movable bending member 22 is pushed by the wire bundle WE and is pushed. Is rotationally displaced to the second posture. Thereby, the electric wire bundle WE can be taken out from the surrounding space 40 which was a closed space. At this time, when the movable bending member 22 is displaced to the second posture, the surrounding space 40 is opened, and the diameter of the opening becomes larger than the diameter of the surrounding space, that is, the diameter of the wire bundle. Therefore, the wire bundle WE in the surrounding space 40 can be easily taken out, which can contribute to a smoother wiring operation.

In particular, in the present embodiment, the movable bending member 22 is always rotated by its own weight of the lever 23 to come into contact with the fixed bending member 21 and to move the movable bending member 22 to the second posture side by a predetermined amount or more. When the rotational displacement is made, a structure is adopted in which the displacement of the movable bending member 22 is suppressed by the rubber band 24 pulling the lever 23 displaced in accordance with this movement in the opposite direction. Therefore, the structure for suppressing the displacement of the movable bending member 22 is very simple,
The wire support BR can be manufactured at low cost.

Further, the electric wire E to be received can be easily guided and accommodated in the surrounding space 40 by the electric wire receiving and guiding portion 50 constituted by the other end portions 21 b and 22 b of the two curved members 21 and 22. Therefore, the electric wire E can be more easily accommodated in the surrounding space 40 which is a closed space. Further, since the other end 21b of the fixed bending member 21 is thicker, when the movable bending member 22 is displaced to the first posture, the other end 2b of the movable bending member 22 is displaced.
2b surely contacts the fixed bending member 21. Therefore,
The substantially circular surrounding space 40 can be reliably formed. In addition, the movable bending member 22 is surely fixed to the fixed bending member 21.
, The movable bending member 22 and the fixed bending member 21 do not overlap in a state of intersecting with each other. As a result, the electric wire E to be received is
There is an advantage that the wire bundle WE is not damaged due to shearing force when the wire bundle WE is sandwiched between the wires 1 and 22, and the received wire bundle WE is not flattened and hinders the tape winding operation.

In addition, when the wiring work is completed,
When pulling up the formed wire bundle WE, the wire bundle WE can be easily taken out of the surrounding space 40 while being guided by the funnel-shaped surface portion 60. Therefore,
Wiring work can be performed more smoothly. Note that the present invention is not limited to the above-described embodiment, and the following modified examples can be considered. FIG. 3 is a perspective view of a main part of a wire support BR according to a modification. Referring to FIG. 3, this modified example is different from the above-described embodiment. In the above-described embodiment, fixed bending member 21 is formed of a pair of plate members 21a, and a spacer S is inserted between plate members 21a. In this modification, the fixed bending member 21 is formed of a single plate, while the movable bending member 22 that rotates is in contact with the movable bending member 22. The portion 21b is provided with a contact plate 21f with which the other end portion 22b of the movable bending member 22 contacts. In the above embodiment, the lever 23 has a substantially L-shape. In the present modification, the lever 23 is formed by a straight plate member, and the plate member 23 extends obliquely downward, and instead of the rubber band 24 used in the above embodiment, The point is that the coil spring 25 is used. Since the other configuration is the same as that of the embodiment, the same reference numerals are given and the description is omitted.

According to this modification, the same operation and effect as those of the above-described embodiment can be obtained. In addition, since the fixed bending member 21 is formed of a single plate material and the lever 23 is formed of a straight plate member, the fixed bending member 21 and the movable bending member 22 are easily manufactured, and the structure of the wire receiving portion 20 is formed. Can be simplified. Thereby, there is an advantage that the cost of the wire support BR can be further reduced. Further, a rubber band 24 is used to pull the movable bending member 22.
In the case where is used, there is a concern that the rubber may be broken due to deterioration of the rubber during use. However, in this modified example, since the coil spring 25 is used, there is no possibility that the rubber will be broken.

As shown in FIG. 3, a long hole 32 is provided in the column 30 and a coil spring 25 is connected to the long hole 32 so that the coil spring 25 bridged between the column 30 and the movable bending member 22 can be formed. , So-called play. Thereby, when the electric wire E to be received is accommodated in the surrounding space 40 from between the two bending members 21 and 22, the movable bending member 22 can be opened more lightly, and there is an advantage that the wiring work becomes easy. is there.

However, the spring 25 and the rubber band 24 can be eliminated. That is, by changing the shape and the like of the lever 23, the movable bending member 22 may be biased toward the fixed bending member 21 only by the own weight of the lever 23. Other shapes of the lever 23 include the lever 2
Any shape may be used as long as the movable bending member 22 can rotate in the direction in which the movable bending member 22 comes into contact with the fixed bending member 21 by its own weight. Further, the shape of the lever 23 may be a shape that does not rotate toward the fixed bending member 21 due to its own weight. In this case, the lever 23 can be biased by the rubber band 24 and the coil spring 24 described above. Further, instead of using the rubber band 24 or the coil spring 24, a torsion coil spring may be arranged concentrically with the pin P. In addition, various design changes can be made within the scope of the present invention.

According to the first aspect of the present invention, since the wire bundle is securely housed in the enclosed space, which is a closed space, the wire protrudes from the wire support during the wiring work. Can be reliably prevented. This can eliminate the troublesome work of repairing the wires that have fallen off from the wire support during the wiring work, and perform a smooth wiring work. Moreover, since the cross-sectional shape of the received wire bundle can be reliably formed into a substantially circular shape, the wiring route difference of each wire in the wiring work can be reduced, and the accuracy as an assembly is improved. Completeness and reliability of the wire harness can be improved. Furthermore, since the cross-sectional shape of the wire bundle can be reliably formed into a substantially circular shape, the wire bundle can be firmly bound by tape winding or the like after the wiring work without dispersing the wire bundle. Accordingly, the wire bundle can be fixed by being bent or bent into a predetermined shape, and a molding protector for fixing the shape can be eliminated from the components of the wire harness. In addition, when the wire bundle is taken out, by opening the second bending member, an opening having a diameter larger than the diameter of the wire bundle is formed in the enclosed space that is a closed space, so that the wire bundle can be easily taken out. Can,
More smooth wiring work can be performed.

[0052] pressurized forte, because the second bending member by the weight of the extending member is biased to close always direction, effectively preventing the once the wires accommodated in the enclosed space will protrude from the surrounding space be able to. Moreover, after the wire bundle is taken out of the surrounding space, the second member is moved by the weight of the extension member.
Returns to the first position. As a result, smoother wiring work can be performed.

According to the second aspect of the invention, the same effects as those of the first aspect of the invention can be obtained. In addition, in the invention according to the present invention, the extension member extending from the second bending member is pulled by the elastic member, so that the surrounding space can be effectively prevented from being opened. Accordingly, it is possible to more reliably prevent the electric wires from protruding from the electric wire support, and it is possible to more reliably form the cross section of the received electric wire bundle into a substantially circular shape. as a result,
There is an advantage that the wiring work can be performed more smoothly, and the wire bundle can be easily fixed or bent or bent into a predetermined shape.

According to the third aspect of the invention, the same effects as those of the second aspect of the invention can be obtained. In addition, the elastic member
Since the second bending member is provided with play, when the second bending member rotates by a predetermined amount or more, a force for suppressing the opening of the surrounding space is added. Therefore, when inserting the laid electric wire into the surrounding space from between the two bending members, it is necessary to slightly rotate the second bending member, but no elastic force is exerted by the elastic member during this rotation. . That is, when the electric wire is inserted into the surrounding space, there is an advantage that the elastic force of the elastic member does not hinder the insertion of the electric wire.

According to the fourth aspect of the invention, the same effects as those of the first or third aspect of the invention can be obtained. In addition, since the electric wire receiving guide can easily accommodate the electric wire to be received in the surrounding space,
Wiring work can be performed easily. According to the fifth aspect , the same effects as those of the first to fourth aspects are obtained. In addition, since the second curved member surely comes into contact with the contact surface, the two curved members do not intersect so as to overlap. Therefore, it is possible to avoid damage caused by the electric wire being pinched between the two bending members. Also,
There is an advantage that the cross section of the wire bundle can be reliably formed into a substantially circular shape without the two bending members overlapping each other and the wire bundle becoming flat.

According to the invention of claim 6 , the same effects as those of the invention according to any one of claims 1 to 5 can be obtained. In addition, the funnel-shaped surface portion has an advantage that the wire bundle in the surrounding space can be easily taken out, and the work of removing the wire harness after the wiring work is facilitated.
