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]

In order to achieve the object of the present invention, a wire harness assembling wire support according to claim 1 receives a wire bundle laid along a wiring board. In a wire harness assembling wire support having a wire receiving portion to be supported and a wire supporting the wire receiving portion at an upper portion and a lower portion attached to a wiring board, the wire receiving portion is provided at an upper portion of the pillar. A closed posture in which a substantially circular surrounding space surrounding the wire bundle is formed by being pivotally connected to each other in a symmetrical state, and by rotating, the tips of the two abut on each other directly above the support pillar, and By rotating, a pair of substantially semi-arc-shaped curved members that are displaced between an open position in which the wire extraction opening that separates the distal ends from each other and opens the surrounding space and that is open directly above the support post, , Less And a rotation restricting means for restricting further rotation of the bending member toward the closed posture when one of the bending members is in the closed posture.

According to this configuration, when the respective bending members are in the closed posture, the ends of the two bending members abut each other to form a substantially circular closed space which is a closed space. That is, when the electric wires are laid, each electric wire can be completely surrounded by the two bending members. Therefore, it is possible to prevent each of the bending members from being opened during the wiring work and the electric wires in the surrounding space 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 the wiring work is completed, the surrounding space can be opened by displacing the two bending members to the open posture, so that the wire bundle can be easily taken out of the surrounding space. At this time, since at least one of the bending members is restricted from being rotationally displaced from the closed posture to the closed posture side by the rotation restricting means, the tip of the at least one curved member is in the closed posture. From the other to the other curved member side. That is, the distal end of at least one of the bending members can be displaced only from directly above the column to the open posture side. Therefore,
The wire bundle formed in the surrounding space can be pulled up just above and pulled out.

Further, since both the curved members are arranged in a substantially semicircular arc and are symmetrically arranged, when the two curved members are displaced to the open posture, the substantially circular surrounding space has a substantially diameter. The part is divided into two parts. Therefore, it is possible to form an opening having a diameter larger than the diameter of the surrounding space by displacing it in the open position, thereby easily taking out the wire bundle in the surrounding space.

In order to achieve the object of the present invention, a wire harness assembling wire support according to claim 2 is the wire harness assembling wire support according to claim 1, wherein the wire support is extended to both curved members. An extension member is provided which constantly urges each bending member toward the closed posture side by its own weight.

According to this configuration, the same operation as that of the first aspect is obtained. In addition, when each bending member is in the closed posture, the posture is always maintained by the weight of the extending member. That is, when each bending member is displaced to the open posture side, it is urged to return to the closed posture side. Normally, the distal ends of both the bending members abut each other to form a substantially circular closed space. A surrounding space is formed. Therefore, even if the two bending members attempt to displace to the open position side during the wiring work, this is suppressed, and as a result, during the wiring work, each of the bending members is opened and the electric wire in the surrounding space is protruded outside. It can be effectively prevented.

Also, since the ends of the two bending members are only in contact at all times, if the wires to be laid are pushed from between the two bending members, the front ends of the two bending members will be Once relatively separated while being pushed away by the electric wire. Thereby, the electric wire can be easily accommodated in the surrounding space. On the other hand, after completion of the wiring work, if the electric wire bundle formed in the surrounding space is grasped by hand and pulled, the two bending members are displaced to the open posture while being pushed away by the electric wire bundle. With this, the wire bundle can be easily taken out of the surrounding space, and after the wire bundle is taken out,
Both the bending members are displaced to the closed posture by the weight of the extension member.

According to a third aspect of the present invention, there is provided an electric wire support for assembling a wire harness according to the first or second aspect. An elastic member is provided which pulls an extension member which is rotationally displaced in accordance with the movement of each bending member in an anti-rotational direction when the member is rotationally displaced to the side.

According to this configuration, the same operation as that of the first or second aspect of the invention is achieved. In addition, when each bending member is rotationally displaced to the open posture side, the elastic member pulls the extending member displaced in accordance with these movements in the opposite direction.
Thereby, displacement of each bending member toward the open posture side can be strongly suppressed. In order to achieve the object of the present invention, an electric wire support for assembling a wire harness according to claim 4 is the electric wire support for assembling a wire harness according to claim 3. And the elastic member and at least one of the extending member and the support are movably connected by a predetermined amount.

According to this configuration, the same operation as the third aspect of the invention is achieved. In addition, since the elastic member is interposed between the extending member and the support with so-called play, even when the elastic member is provided, the two curved members are always in contact with each other even if the elastic member is provided. It will be in a state just being. Therefore, if the elastic member is provided without the play,
Both bending members are in a state of being urged so as to be constantly pressed against each other by the elastic force of the elastic member, and it is difficult to push the wire to be wired from between the two bending members,
Such an inconvenience does not occur in the invention according to the present claim.

According to a fifth aspect of the present invention, there is provided an electric wire support for assembling a wire harness according to any one of the first to fourth aspects. The movement restricting means is provided on at least one of the bending members, and includes a contact surface member that comes into contact with the support when the bending member is in the closed posture.

According to this configuration, the same operation as the invention according to any one of the first to fourth aspects is exerted. In addition, since the contact surface of the contact surface member abuts on the column, at least one of the bending members is not further displaced from the closed posture toward the other bending member. Therefore, the tip portion of at least one of the bending members is displaced in a range from directly above the column to the open posture side. Therefore, the electric wire to be laid can be easily accommodated in the surrounding space from directly above.

In order to achieve the object of the present invention, the wire support for wire harness assembly according to claim 6 is the wire support for wire harness assembly according to claim 5, wherein the contact surface member is the wire support for wire harness assembly according to claim 5. It is characterized by being formed integrally with the extension member.

According to this configuration, the same operation as that of the fifth aspect is obtained. In addition, the contact surface member and the extension member can be integrally formed, and the number of parts can be reduced. To achieve the object of the present invention, an electric wire holder for assembling a wire harness according to claim 7 is provided.
In the wire support for wire harness assembly according to any one of the above, the distal end portion of each bending member is bent in a direction opposite to the bending direction of the bending member, and both bending members are displaced to the closed posture. Are characterized in that they form a pair of outwardly open wire receiving guides.

According to this configuration, the same operation as that of the invention according to any one of claims 1 to 6 is achieved. In addition, the electric wire receiving guide has a so-called funnel shape from the outside to the inside with respect to the surrounding space. Therefore, when the electric wire to be received is pushed from between the two curved members, the electric wire is accommodated in the surrounding space while being guided by the electric wire receiving guide.

In order to achieve the object of the present invention, a wire harness for wire harness assembly according to claim 8 is at least one of the wire supports for wire harness assembly according to claim 1. The distal end of the curved member has a contact surface portion with which the distal end of the other curved member contacts in a state of being displaced to the closed posture.

According to this configuration, the same operation as the invention according to any one of the first to seventh aspects is achieved. In addition, when the other bending member is displaced to the closed posture, the tip of the other bending member surely comes into contact with the contact surface of the contact surface provided at the tip of the one bending member. Therefore, the surrounding space which is a closed space can be reliably formed. In order to achieve the object of the present invention, an electric wire support for assembling a wire harness according to claim 9 is provided.
In the wire support for wire harness assembly according to any one of the above, at a predetermined portion inside the surrounding space of the distal end portion of one of the bending members is bent in a direction opposite to the bending direction of the one bending member. A first curved surface is formed, and
A second curved surface which is curved in a direction opposite to a bending direction of the other bending member is formed at a predetermined portion inside the surrounding space at a distal end portion of the other bending member, and is displaced to a closed posture. In this state, the curved surfaces form a funnel-shaped surface portion in which a part of the inner peripheral surface that defines the surrounding space gradually narrows radially outward of the surrounding space.

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

And are assembled in a pre-designed form.

Referring to FIGS. 1 and 3, wire support B
R is an electric wire receiving portion 20 for receiving and supporting each electric wire E laid along the wiring board 10;
At the upper end. Note that FIG.
Then, although only one wire E is illustrated,
As the wiring operation progresses, the electric wire receiving portion 20 receives the electric wire bundle including the plurality of electric wires E. Prop 30
Is a member in the shape of a round bar, for example, and its upper portion is formed in a so-called clevis shape in order to support the electric wire receiving portion 20. At the lower part of the column 30, a fixing washer 3 is provided.
A nut 31 formed with 1a is attached. A male screw 32 is formed from the nut 31 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. The wire support BR is fixed to the wiring board 10 by applying a fastening nut N to the male screw 32 from the lower surface side of the wiring board 10.

One of the features of the present embodiment lies in the structure of the electric wire receiving portion 20. The electric wire receiving portion 20 includes a pair of curved members 21 and 22 having a substantially semicircular arc shape. 21 and 22 can be displaced between a closed posture shown in FIG. 1 and an open posture shown in FIG. 4. Both bending members 21 and 22 are formed with contact pieces 27 and 28. When the bending members 21 and 22 are in the closed position, the contact pieces 27 and 28 are in contact with the columns 30, so that the bending members 21 and 22 can be positioned in the closed position. In other words, when the two bending members 21 and 22 are in the closed position, the tips 21b and 22b abut each other directly above the support 30 and the electric wire E is housed in a state where the wire E is surrounded. A substantially circular surrounding space 40 is defined. On the other hand, when both the bending members 21 and 22 are in the open position, the distal ends 21b and 22b are separated from each other, and the surrounding space 40 is opened to open the wire opening 41 (FIG. 4). ) Is formed directly above the support column 30. Each of the bending members 21 and 22 includes a respective one of the bending members 21 and 22.
231 and 232 are provided for rotating the levers 231 and 232 in a direction in which they are always in a closed position.
The spring 24 that pulls the bending members 21 and 22 in the anti-displacement direction by a force corresponding to the displacement when the first and second members 22 are turned to the open position is connected.

Hereinafter, the electric wire receiving portion 20 will be described in detail. The wire receiving portion 20 includes a first bending member 21, a second bending member 22, contact pieces 27 and 28, levers 231 and 231.
32 and a spring 24. First bending member 21
Is made of a substantially semicircular arc plate. First bending member 2
The first distal end portion 21b is smoothly curved in a direction opposite to the bending direction of the first bending member 21. First bending member 21
The first bending member 21 is attached to the base 30 a of the support 30.
There is provided a mounting hole (not shown) for mounting on the upper part.

The second bending member 22 is made of a plate material,
It is formed symmetrically with the bending member 21. That is, the second bending member 22 is formed in a substantially semicircular arc shape, and is bent in a direction opposite to the bending direction of the first bending member 21. The distal end portion 22b of the second bending member 22 is smoothly curved in a direction opposite to the bending direction of the second bending member 22. A mounting hole (not shown) for mounting the second bending member 22 on the upper portion of the column 30 is provided in the base end portion 22 a of the second bending member 22.

As shown in FIG. 1, both bending members 21 and 22
In the closed state, the distal ends 21b and 22b of the two bending members 21 and 22 are in contact with each other and separated from each other. That is, the tip portions 21b, 2
2b are gradually expanded outward from the surrounding space 40. The gradually expanded portion formed by the tips 21b and 22b constitutes an electric wire receiving guide 50. The electric wire receiving and guiding portion 50 can easily accommodate the electric wire E to be laid in the surrounding space 40 in a guided state.

When the tips 21b and 22b come into contact with each other, the surrounding space 4b is formed by these 21b and 22b.
A funnel-shaped surface portion 60 is formed on the 0 side. This funnel-shaped surface part 6
Numeral 0 is constituted by the curved surfaces 21c and 22c of the two curved members 21 and 22 on the surrounding space 40 side. That is, FIG.
As shown in FIG. 3, a part of the inner peripheral surface that defines the surrounding space 40 by the funnel-shaped surface portion 60 (the portion directly above the column 30).
Is gradually narrowed radially outward.
Thereby, the wire bundle can be easily taken out from the surrounding space 40.

The two bending members 21 and 22 are arranged symmetrically with respect to the axis of the column 30 in a state where they are superposed one on the other. This will be described in detail with reference to FIGS.
The first bending member 21 is arranged on the middle front side, and the second bending member 22 is arranged on the other side in a state of being superposed on the first bending member 21. Base end 21 of both bending members 21 and 22
a, 22 a are attached to the support 30. That is, the connecting pin P1 is inserted from the outside of the upper part of the clevis-shaped column 30, and the connecting pin P1 is inserted into the mounting holes provided in the base ends 21a and 22a of the curved members 21 and 22. Thus, the two bending members 21 and 22 are rotatably supported by the connecting pin P1.

The levers 231 and 232 are made of substantially L-shaped plate members, and extend to the first bending member 21 and the second bending member 22, respectively. The lever 231 is connected to the base end 21 a of the first bending member 21 so that the first bending member 21
And are formed integrally with it. The lever 232 is formed integrally with the second bending member 22 so as to be continuous with the base end portion 22a of the second bending member 22. But lever 2
31 and 232 are formed separately from the respective bending members 21 and 22, and each bending member 2 is formed by a required fastening member such as a bolt.
You may make it fix to 1 and 22.

The lever 231 is configured to rotate clockwise around the connecting pin P1 by its own weight. On the other hand, the lever 232 rotates counterclockwise in the figure around the connecting pin P1 by its own weight. That is, normally, the lever 2
The weights of the bending members 21 and 22 are biased so as to rotate together with the levers 231 and 232 in the closing posture direction (the direction in which the surrounding space 40 is defined) by the weight of the bending members 21 and 232. , 22 tips 21b, 22b
The members are in contact with each other.

The spring 24 is mounted in a state where the respective ends 23a and 23b of the levers 231 and 232 and the support 30 are connected. Specifically, each lever 23
Pins P2 are provided on the ends 23a and 23b of the first and second 232, and mounting screws P3 are provided on the columns 30. Then, both ends of the spring 24 are fixed by the pins P2 and the mounting screws P3. Moreover, this spring 24
When both the bending members 21 and 22 are in the closed posture, that is, when the distal ends 21b and 22b of the both bending members 21 and 22 are in contact with each other (the state shown in FIG. 1), the lever 231 is in the steady state. 232 is set so as not to exert any force.

That is, at all times (the state of FIG. 1), the lever 2
The two weights 21 and 22 are only in contact with each other due to the weight of the weights 31 and 232, and only when the two weights 21 and 22 are rotationally displaced toward the open position, a size corresponding to the amount of the displacement is reached. The levers 231 and 232 are pulled back by the force, and the rotational displacement of the bending members 231 and 232 to the open posture side is suppressed. This suppressing force is given by an elastic force caused by the extension of the spring 24, and this elastic force corresponds to the displacement amount of the levers 231 and 232 displaced in accordance with the movement of each of the bending members 231 and 232. doing.

Therefore, if the rotation angle of each of the bending members 231 and 232 is small, the displacement of the levers 231 and 232 is also small, and the levers 231 and 232 are pulled back to suppress the rotation displacement of each of the bending members 231 and 232. Although the force is small, if the rotation angle of each of the bending members 231 and 232 is large, the amount of displacement of the levers 231 and 232 becomes large.
1 and 232 are strongly pulled back and the respective bending members 231 and 23
2 is strongly suppressed.

The spring 24 is connected to the levers 231 and 232
Alternatively, the connecting portion with the column 30 may be connected with a so-called play. With this configuration, when the initial displacement of the levers 231 and 232 toward the open position is equal to or less than the predetermined amount, the elastic force of the spring 24 is not applied to the levers 231 and 232. That is, each of the bending members 231 and 231
The rotation force of the springs 24 is applied only when the rotation of the levers 32 is more than a predetermined amount. When the rotation amounts of the levers 32 are smaller than the predetermined amount, the levers 231 and 232 are brought into contact with each other by the biasing force of their own weight.

The contact pieces 27 and 28 are provided on the first bending member 21 and the second bending member 22, respectively, and are formed integrally with the first bending member 21 and the second bending member 22. That is, in the present embodiment, the first bending member 21, the lever 231 and the contact piece 27 are integrally formed, and the second bending member 22, the lever 232 and the contact piece 28 are integrally formed. Is formed.

As shown in FIGS. 1 and 3, the contact piece 2
Reference numerals 7 and 28 denote plate members formed to project downward from the first bending member 21 and the second bending member 22, respectively. When the bending members 21 and 22 are turned from the open position to the closed position, the contact pieces 27 and 28 are
Abuts on the upper end portion. Thus, even if each of the bending members 21 and 22 further attempts to rotate toward the closed posture, the rotation can be restricted.

Referring to FIG. 3, both bending members 21 and
The thickness dimension of the tip portions 21b and 22b of the 22 is thicker than other portions. For this reason, both bending members 21,
When the pivot 22 is turned to the closed position, the distal end 21
a and 22a are reliably brought into contact with each other. Therefore, the tip portions 21b and 22b of the bending members 21 and 22 do not intersect with each other so as to overlap. Instead of increasing the thickness of the tip portions 21b and 22b, a contact plate may be attached so that the two portions 21b and 22b contact each other.

In FIG. 1, both the bending members 21 and 22 are rotated and are in a closed posture. In this closed position, both 21 and
The tips 21a and 22a of the abutment 22 abut on each other directly above the column 30, thereby forming a substantially circular surrounding space 40 for accommodating the electric wire E. On the other hand, in FIG. 4, both the bending members 21 and 22 are rotated and are in an open posture state. In this open position, the distal end portions 21a, 22
a are separated from each other, whereby the housed wire bundle WE
An opening portion 41 for taking out is formed right above the column 30. In this state, the opening 41 is
, Ie, an opening diameter larger than the diameter of the wire bundle WE.

Next, the operation and effect of this embodiment will be described. The two bending members 21 and 22 are connected to each other at the tip portions 21b and 2 respectively.
Since 2b is in contact, no gap is formed between the two 21 and 22, and an enclosed space that is a completely closed space is formed. Therefore, when the electric wires E are laid, each electric wire E accommodated in the surrounding space 40 is connected to both the bending members 21 and 2.
It is completely surrounded by 2. Moreover, both bending members 2
1 and 22 are displaced toward the open position, the lever 2
Displacement to the open posture side is suppressed by the urging force of the weights of the components 31 and 232. Thereby, it is possible to prevent the electric wires E in the surrounding space 40 from protruding outside due to the opening of the two bending members 21 and 22 during the wiring work. As a result, it is possible to eliminate the correction work due to the drop of the electric wire E once received by the electric wire receiving portion 20, and to perform the wiring work smoothly.

In addition, since the distal ends 21b and 22b of the two bending members 21 and 22 are always in contact with each other, the electric wire E to be laid is connected to the two bending members 2 and 22 in the state shown in FIG.
If the two bending members 21 and 22 are pushed down by the electric wire E, the two bending members 21 and 22 are slightly displaced to the open posture side, and the electric wire E is easily pushed into the surrounding space 4.
0 can be accommodated. That is, the surrounding space 40
Although the wire is always a completely closed space, the wire E can be easily accommodated in the surrounding space 40 at the time of wiring work.

In this embodiment, the spring 24 is provided, and the elastic force of the spring 24 causes the two bending members 21 and 22 to be opened to return in the closing direction. It is possible to effectively prevent the surrounding space 40 from opening due to the movement, and it is possible to reliably prevent the electric wire E from protruding from the surrounding space 40 to the outside. In particular, when the spring 24 is connected with a so-called play, when the electric wire E is pushed in, the two bending members 21,
Even if the valve 22 is slightly displaced toward the open position, the elastic force of the spring 24 is not applied to both the bending members 21 and 22. Therefore, the work of housing the electric wire E in the surrounding space 40 does not become difficult. In addition, as a structure for giving this play, for example, the support 30 or the levers 231 and 231 are provided.
A long hole may be provided in the end portions 23a and 23b of the 32, and the spring 24 may be mounted by inserting the mounting screw P3 and the pin P2 into the long hole.

Since the surrounding space 40 has a substantially circular shape, the electric wire bundle constituted by the received electric wires E is formed such 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 cross-sectional shape of the bundle of electric wires to be received can be surely formed into a substantially circular shape. 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. 4, after completion of the wiring work, if the electric wire bundle WE formed in the surrounding space 40 is grasped by hand and pulled upward, the electric wire bundle WE is pushed by the electric wire bundle WE and the two bending members 21 are pushed. , 22 are rotationally displaced to the open position. Thereby, the wire bundle WE can be taken out of the surrounding space 40. At this time, since the opening 41 for taking out the electric wire is formed directly above the column 30, the electric wire bundle WE can be pulled out directly above.

By the way, as shown in FIG.
In the case where is branched in three directions on the wiring board 10 (when it is wired in a cross shape), it is necessary to collectively remove the parts branched in these three directions and to remove it directly above. .
More specifically, first, referring to FIG. 5, the wire bundle WE constituting the trunk line portion is branched in three directions by the wire support BR, and each of the wire bundles WE1 and WE1 as a branch line portion.
The wire bundle WE2 and the wire bundle WE3 are configured. Reference numeral 2 denotes a conventional U-shaped wire support, which supports the ends of the wire bundles WE1, WE2, and WE3 as the branch wires in a positioned state. Reference numerals C1, C2, and C3 indicate connectors provided at the ends of the electric wires.

In this state, if the portion supported by the wire support BR is to be lifted diagonally upward (for example, in the direction of the white arrow), the connector C3 is in contact with the wire support 2, so the connector The wire bundle WE3 cannot be removed because C3 is caught. If the portion supported by the wire support BR is forcibly pulled up in this state, the wire bundle WE3 may be pulled and its length may change. For this reason, in order to remove the portions branched in three directions as shown in FIG. 5, the wire bundles WE1, WE2, and WE3 must be collectively removed directly above.

As described above, in this embodiment, the electric wire bundle WE
Can be pulled out just above, so that an external force such as tension can be prevented from being applied to the wired wire bundle WE, and as a result, an error occurs in the length of the measured wire bundle WE. It can be removed from the wiring board 10 without causing it to occur. In addition, when the two curved members 21 and 22 are displaced to the open position, the substantially circular surrounding space 40 is divided into two at the substantially diameter portion to form an opening 41 having a diameter larger than the diameter of the wire bundle WE. Therefore, the wire bundle WE in the surrounding space 40 can be easily taken out, and a more smooth wiring operation can be performed.

In particular, in this embodiment, the two bending members 21 and 22 are normally rotated and biased by their own weights of the levers 231 and 232 to come into contact with each other, and when the bending members 21 and 22 are rotationally displaced from this state to the open posture side. Are both curved members 21 and 22
The springs 24 pull the levers 231 and 232 that are displaced together with the two curved members 21 and 2
2 is employed to suppress the rotational displacement. Therefore, the structure for suppressing the displacement of the bending members 21 and 22 is very simple, and 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 distal end portions 21 b and 22 b of both the bending 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, the tip portions 21b, 2 of the two bending members 21, 22 are provided.
2b is thicker, so that when displaced to a closed posture, the two end portions 21b and 22b surely come into contact with each other. Therefore, the surrounding space 40 which is a closed space can be reliably formed. In addition, since the two bending members 21 and 22 surely come into contact with each other, the two bending members 21 and 22 do not overlap each other in an intersecting state. This prevents the electric wire E to be received from being damaged by the shearing force between the two bending members 21 and 22 or the received electric wire bundle WE being flattened and hindering the tape winding operation. There is an advantage.

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. 6 is a perspective view of a main part of a wire support BR according to a modification. Referring to FIG. 6, this modification differs from the above-described embodiment. In the above-described embodiment, each of the bending members 21 and 22 is supported by a single connection pin P1. In this modification, the first bending member 21 is supported by the connection pin P5, the second bending member 22 is supported by the connection pin P6, and the upper end UE of the support 30 is The upper end portion UE, the first bending member 21 and the second bending member 22 are detachable, and are configured as a unit. In addition, about the structure similar to one Example,
The same reference numerals are given and the description is omitted.

As shown in FIG. 5, the upper end UE of the column 30
Has a base 35 attached to the support 30 and a stay 36 provided on the upper surface of the base 35. Base 3
5 is formed in a block shape, and on the lower end surface thereof,
A leg 35a on which the male screw 37 is formed is formed to protrude. The leg 35 a is provided with a mounting hole 39 provided in the support 30.
, So that the upper end portion UE is fixed to the support 30.

The stay 36 is made of a plate material formed in a semicircular arc shape. At both ends of the stay 36, through holes through which the connecting pins P5 and P6 pass are provided. The bending members 21 and 22 are respectively connected to the connection pins P5 and P5.
It is rotatably supported via P6. However, in one embodiment, each of the curved members 21 and 22 is
a and 22a are supported by a single connecting pin P1, but in this modified example, the central portion 2 of each of the curved members 21 and 22 is provided.
1m and 22m are supported by the connecting pins P5 and P6, respectively.

Paying attention to the first bending member 21, the lever 233 extended therefrom has a substantially rectangular shape. The portion 234 of the lever 233 also serves as the contact piece 27 shown in the embodiment. That is, as shown in FIG. 5, when the first bending member 21 is displaced to the closed posture, a part 234 of the lever 233 comes into contact with the side surface of the base 35. Note that the shape of the lever 233 is not limited to a substantially rectangular shape, and a part thereof is
When the first bending member 21 is displaced into the closed posture by contacting the first bending member 5, the rotation of the first bending member 21 can be restricted to position the first bending member 21 in the closed posture. Further, since the second bending member 22 has a symmetrical shape with respect to the first bending member 21, the description thereof is omitted.

According to this modification, the same operation and effect as those of the above embodiment can be obtained. In addition, the upper end UE of the column 30 to which the first bending member 21 and the second bending member 22 are connected.
Is detachable from the column 30, so that it can be easily replaced with another one. Therefore, if a plurality of types of the upper end portion UE are prepared in accordance with the specifications of the wire harness, the upper end portion UE can be changed even if it is desired to change the shape or the like of the two curved members 21 and 22 for each specification. There is an advantage that it is possible to easily cope with a specification change only by making a change.

In addition, for example, a rubber band or the like can be used in place of the spring 24 shown in the above-described one embodiment and the modification. In addition to using the spring 24 and the rubber band, a torsion coil spring may be used concentrically with the connecting pins P5 and P6. However, the spring 24 and the rubber band can be eliminated. Further, referring to FIG. 1, a contact piece 27 for restricting rotation of the two bending members 21 and 22,
28 can eliminate either one.

According to the first aspect of the present invention, the electric wire bundle is securely housed in the enclosed space, which is a closed space, so that the electric wires laid during the wiring work can be removed from the electric wire support. It can be reliably prevented from protruding. Therefore, it is possible to eliminate the troublesome work of restoring the wires that have fallen off from the wire support during the wiring work, and to perform the smooth wiring work. Moreover, since the cross-sectional shape of the received wire bundle can be formed to be substantially circular, the wiring route difference of each wire in the wiring work can be reduced, thereby improving the accuracy as an assembly. Thus, the degree of completeness and reliability of the wire harness can be improved. In addition, since the cross-sectional shape of the received electric wire bundle can be reliably formed into a substantially circular shape, the electric wire bundle can be firmly bound by tape winding or the like without breaking the electric wire bundle during the wiring work. As a result, the wire bundle can be bent or bent into a predetermined shape and fixed, and as a result, a forming protector for fixing the shape can be eliminated from the components of the wire harness. Furthermore, when taking out the laid wire bundle, the opening portion having a diameter larger than the diameter of the wire bundle is formed by opening both the bending members, so that the wire bundle can be easily taken out, and a more smooth cloth Line work can be performed. In addition, since the received wire bundle can be pulled out right above, even if the wire bundle is branched and supported in three directions on the wiring board, it can be easily removed from the wiring board. Can be. As a result, an even smoother wiring operation can be performed. In particular, there is an advantage that there is no restriction on the direction in which the wire bundle is taken out by making the opening of the opening sufficiently large.

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, since the two bending members are constantly biased in the closing direction by the weight of the extension member, it is possible to effectively prevent the electric wire once housed in the surrounding space from protruding from the surrounding space. Moreover, after the wire bundle is taken out, the two bending members return to the closed position due to the weight of the extension member. As a result, smoother wiring work can be performed.

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, in the invention according to the present invention, since the elastic member pulls the extending member extended to both the curved members, the opening of the surrounding space can be effectively suppressed. 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,
In addition, the wiring work can be performed more smoothly, and the work of fixing the wire bundle by bending or bending it into a predetermined shape becomes easier.

According to the fourth aspect of the invention, the same effects as those of the third aspect of the invention can be obtained. In addition, the elastic member
Since it is provided with play, when the two bending members rotate by a predetermined amount or more, a force for suppressing the opening of the surrounding space is applied. Therefore, when inserting the laid electric wire into the surrounding space from between the two bending members, it is necessary to slightly rotate both the bending members, but no elastic force is exerted by the elastic members during this rotation. That is, although the surrounding space is a closed space, 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 fifth aspect of the invention, the same effects as those of the first to fourth aspects can be obtained. In addition, in the invention according to the present invention, at least one of the curved members is displaced in a range in which the distal end portion is directly above the column and on the open posture side by the contact surface of the contact surface member abutting on the column. Therefore, when the wires to be wired are accommodated in the surrounding space, the wires can be inserted straight from directly above, and the wiring operation can be easily performed.

According to the sixth aspect, the same effects as those of the fifth aspect are obtained. In addition, since the contact surface member and the extending member are integrally formed, the number of components can be reduced, and the wire support can be manufactured at lower cost. According to the seventh aspect, the same effects as those of the first to sixth aspects can be obtained. In addition, since the electric wire can be easily guided and accommodated in the surrounding space by the electric wire receiving and guiding portion, the wiring work can be performed more easily.

According to the invention of claim 8, the same effects as those of the invention of any of claims 1 to 7 can be obtained. In addition, the abutting surfaces ensure that the distal ends of the two bending members abut, so that the two bending 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. Further, there is an advantage that the wire bundle does not become flattened due to the overlapping of the two bending members, and the cross-sectional shape of the wire bundle can be reliably formed into a substantially circular shape.

According to the ninth aspect, the same effects as those of the first to eighth aspects 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.
