DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art Conventionally, power cables, communication cables, and the like (hereinafter, referred to as cables) are wired along indoor floors, walls, ceilings, panels of electronic equipment housings (hereinafter, wall surfaces, etc.). For such wiring, a cable wiring tool that can change the wiring direction while holding cables along a wall surface or the like is used.

In recent years, the use of optical cables as communication cables has been rapidly increasing. As a general characteristic of this optical cable, if it is bent excessively, the transmission performance may be degraded, and if it is further bent, in the worst case, the optical cable may be broken and disconnected. Therefore, it is necessary to prevent the wiring from being bent with a curvature greater than a predetermined value.

[0004]

However, the conventional cable wiring device has the following problems.
Conventional cable wiring tools are made with the assumption that electrical cables consisting mainly of metal wires are wired.When used for wiring optical cables as described above, they may be bent beyond the allowable curvature of the optical cables. However, it was not always suitable for optical cable wiring.

For example, in a wiring path that is bent from a vertical wall to a horizontal ceiling or bent along a corner of a pillar, a path that is bent at a right angle called an elbow is conventionally used. Although such cable elbows were used, such elbows are bent as much as possible along the walls and the like, so the optical cable will be bent excessively, transmission performance will be reduced, and in the worst case, There was a risk that the optical cable would break and break.

[0006] Therefore, the present invention provides a cable that can be wired without excessively bending cables.
And to provide a preventing resulting Luque Buru wiring tool deterioration and disconnection of transmission performance.

[0007]

In order to achieve the above object, first, a characteristic cable wiring as described below is used.

Two guiding passages for guiding both ends of the accommodated cables in a wiring direction forming a predetermined angle without being bent to the predetermined curvature or more, and a position for communicating the annular space with the guiding passage. Alternatively, it is possible to move to a position where the annular space and the guide passage are shut off, and at the position where the communication is established, a tip of cables inserted into the annular space and proceeding along the annular space is moved inside the guide passage. And a cable guiding piece for advancing into the annular space while abutting the distal end of the cables at the blocking position.

According to a second aspect of the present invention, there is provided a cable wiring device which is attached to a wall or the like and changes the wiring direction of the cables while holding the cables, and crosses at a predetermined angle to form a corner. With respect to the two surfaces, in the cable wiring tool used when wiring the cables from one plane along the respective planes, over the corner, and to the other plane, the allowable maximum curvature is specified, respectively.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the characteristic cable
According to this cable wiring method, a method of wiring will be described. In this method, cables are curved in a plane parallel to one plane to be in a plane parallel to one plane and a plane parallel to the other plane. Since the cables are guided on a line and curved in a plane parallel to the other plane, cables can be routed so as to cross over corners. At this time, cables are not bent in a plane parallel to each plane. The cables need not be far apart from each plane. Therefore, wiring can be performed without protruding cables into the space, and dead space can be reduced. Also,
Since the cables do not separate from the wiring surface, there is no fear of catching anything on the cables after wiring. Therefore, it is extremely useful in the case of using cables that are weak to bend, such as optical cables, for wiring from the floor to the wall, from the wall to the ceiling, or over the corners of columns.

In order to perform wiring through a characteristic route such as the above-described cable wiring method , cables can be passed through a duct forming the characteristic route, or the cables can be gripped at a position along the characteristic route. This can be achieved by attaching a large number of various clamps and holding cables.
However, when laying cables such as an optical cable, for which the maximum allowable curvature is specified, it is necessary to check at the work site whether or not the curvature of the cables is less than the maximum allowable curvature. It is troublesome.
In that regard, it is convenient to use the cable distribution tool of the present invention .

That is, when the cable wiring device of the present invention is used.
If, by the cable wire fitting, since the held by bending the cables at a predetermined curvature equal to or below the allowable maximum curvature, the
When the wiring is performed by the characteristic cable wiring method, the cables do not bend at the portion held by the cable wiring tool. Therefore, even when the optical cable is wired, the transmission performance does not deteriorate and the optical cable does not break or break. In addition, since the allowable maximum curvature differs depending on the characteristics of the cables used for wiring, it cannot be specified by numerical values or the like, but as a specific example, as a relatively general quartz optical fiber, It is known that the allowable minimum radius of curvature is 30 mm. In this case, by setting the radius of curvature to 30 mm or more, it is possible to bend at a predetermined curvature equal to or less than the maximum allowable curvature.

Further, as the cabling tool according to claim 1, if it is a structure in which the cable wire fitting to accommodate the cables to the annular space, unlike a construction for winding cables on the core material, loop The cables wound in the shape are held loosely in a state where the diameter of the loop can be further reduced. Therefore, when the tension applied to the cables is increased, the stress applied to the cables is reduced by reducing the diameter of the loop. Therefore, even when the optical cable is wired, the cable is not broken. Also, when the cable wiring tool has a structure to accommodate cables in an annular space, it differs from a configuration in which cables are accommodated in a non-annular space,
Even when the tension applied to the cables is increased, the diameter of the loop does not become excessively small, so that no bending or the like is caused.
There is no reduction in transmission performance or disconnection.

[0017] Incidentally, if the curvature in the previous SL allowable maximum curvature following a predetermined curvature, it is possible even without wound a cable such in a loop to change the wiring direction. As such cable wire fitting, by providing a ring-shaped space by 1/4, which changes the wiring direction 90 degrees, a ring-shaped space 1
By providing only / 2, there can be cited one that changes the wiring direction by 180 degrees. However, if the cables are simply curved and held, if the cables are held too loosely, the cables may be easily displaced in the axial direction. There is a risk that extra stress will be applied to the system.
In this respect, when held by a cable such in a loop, simply compared with the case of holding by bending, since the cables can not shift in the axial direction is facilitated, it is possible to gently hold the cables, the There is an advantage that no extra stress is applied to the cables.

[0018] In the configuration according to claim 1, wherein the annular space and guide channel is formed as a space surrounded by both provided in the case wall, the shape of this wall, the size, the arrangement, etc., the Any form is possible as long as the annular space and the guide path can be formed.For example, except for necessary portions such as a cable insertion port and the like, the wall surface is all necessary. Other than the part, a discontinuous wall surface may be used.

As described above, the curvature when the cables are wound in a loop shape varies depending on the characteristics of the cables used for wiring, but the allowable minimum curvature radius is 30 mm.
In this case, the radius of curvature of the inner peripheral portion of the annular space may be set to 30 mm or more. In particular, in the case of an optical cable, it has the property of trying to stretch linearly against bending, so if it is not applied with excessive tension, it will spread evenly as if it is stored in an annular space so as to increase the diameter of the loop, A loop with a larger radius of curvature than the inner periphery of the annular space is maintained,
In the annular space, it is not bent with a radius of curvature smaller than the minimum allowable radius of curvature.

Further, in guiding the cables from the annular space to the outside by the guide passage, it is important that the cables are not curved beyond the curvature of the annular space.
In order to provide such a guide path, when cables or the like wound in a loop in an annular space are regarded as a circle, they are allowed on a straight line tangent to the circle or within a curve tangent to the circle. The guide path may be arranged on a curve having a smaller curvature (ie, a larger radius of curvature) by adjusting the shape and dimensions so that both ends of the cables can be guided. The angle formed by the two guide paths can be arbitrarily set according to the intended wiring direction.

In addition, any method may be used for storing the cables and the like in the annular space. In a specific example, the case forming the annular space can be divided into a main body and a lid. Then, wrap the cables in a loop beforehand, put them in the main body, attach the lid to the main body, loosely wrap the cables around the inner periphery of the main body annular space, and then put the lid on the main body Can be considered. In this case, by arranging a sponge-like cushioning material or the like in the annular space together with the cables before attaching the lid, it is also possible to prevent the cables from shifting in the axial direction while protecting the cables. . Also, the cables can be stored in the annular space by a method of sequentially inserting the cables from one end through one guide passage.

Further , the guide passage is provided in the vicinity of an outside opening of the guide passage.
Cable that is led out of the guideway
Separate cable guides arranged to guide in a fixed direction
If a connecting portion that can be connected to the member is provided, a separate cable guiding member disposed outside can be connected to the connecting portion. The cable guide member is arranged to guide the cables led out of the guide passage in a predetermined direction.Specific examples include a tubular or gutter-like duct,
There are pipes and tubes. With this configuration,
By combining the present cable wiring tool and the cable guiding member, a cable passage serving as a wiring path can be easily formed.

The position where the connecting portion is provided is near the outside opening of the guide passage, and is not strictly limited any more. Is formed at a position where connection is possible in the state of being arranged at the position.

The specific shape and the like of the connecting structure in the connecting portion may be appropriately determined according to the shape and the like of the cable guiding member. An engagement structure in which the connection is made by engagement of the concave portion and the convex portion, and the engagement is released by elastic deformation of at least one of the concave portion or the convex portion, Is desirably constructed so that it can be fitted into the cable guide member exactly, because it can be connected without using screws, adhesives or the like.

By using the cable wiring tool according to the first aspect described above, wiring by the above cable wiring method can be performed very easily. It should be noted that the cable wiring tool according to the first aspect is extremely useful not only in the case where the cables are routed beyond the angle formed by the two planes but also in the case where the wiring direction is changed in one plane.

The cable wiring method according to any one of claims 2 to 4 also provides the above cable wiring method.
The hardwired be very easily carried out.

[0027]

[0028] Also in cabling tool according to any one of claims 2 to 4, it may be configured the same annular space and introducing passage and cabling device as in Claim 1 wherein.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention.

[0030]

Next, in order to further clarify the embodiment of the present invention, an example of a cable wiring tool to which the present invention is applied will be described with reference to the drawings. The embodiments described below are merely examples of the embodiments of the present invention, and the embodiments of the present invention are not limited to the specific shapes and the like illustrated below.

[ First Example ] As shown in FIGS. 1 (a) and 1 (b), a cable wiring device 1 is made of a synthetic resin, and has a rectangular parallelepiped case 3 having one opening. The case 3 includes a rectangular plate-shaped lid 5 for closing an opening surface of the case 3, and two cylindrical connecting portions 7 and 9 protruding from a side surface of the case 3. The connecting portions 7 and 9 are cylindrical bodies each having a square shape in the cross section. Of the four side surfaces, three side surfaces having a U-shape in cross section are fixed to the case 3 side, and one remaining side surface is formed. It is formed integrally with the lid 5.

Of these configurations, case 3 is the same as that shown in FIG.
(A), as shown in FIG. 2 (b), an annular space 11 formed by internal partition walls 3a to 3e, and a case 3 therein.
The first guide passage 13 formed by the inner partition wall 3b, the side wall 3f, and the connecting portion 7, and the inner partition wall 3 of the case 3
d, the side wall 3g, and the second
And a guide path 15. Among them, the annular space 11
Is a space in which the cable c can be accommodated by being wound in a loop shape with a curvature smaller than the allowable maximum curvature. The radius is 30 mm. Therefore,
The cable c wound in a loop shape is not bent at a greater curvature. Also, the first and second guide passages 1
Reference numerals 3 and 15 denote passages for communicating the annular space 11 with the outside of the case 3, and both ends c1 and c2 of the accommodated cable c.
Without curving more than the curvature (that is, in the embodiment,
The radius of curvature should not be smaller than 30 mm), 9
It is guided in the wiring direction at 0 degrees.

The lid 5 has a slightly tapered peripheral side surface 5a, and is attached so as to be placed on a step 17 formed on the side walls 3f to 3i of the case 3.
As shown in FIG. 2 (c), the step 17 of the case 3 has projections 17a formed at several places along the circumferential direction at appropriate intervals. The projections 17a are formed as shown in FIG. The lid 5 is fixed to the case 3 by engaging with the peripheral side surface 5a. In the annular space 11, FIG.
As shown in (b), a cable temporary fixing piece 19 is protruded. When the cover 5 is removed and the cable c is stored in the annular space 11, the cable temporary fixing piece 19 temporarily fixes the cable c wound in a loop shape so that the cable c is in the annular space 1.
2 is provided at four places in the annular space 11 as shown in FIG.

Further, as shown in FIGS. 2A and 2B, the connecting portion 7 has a groove 7a formed along the outer peripheral surface, and as shown in FIGS. 3A and 3B. As shown in (1), it can be connected to a separate cable guiding member 21. The cable guide member 21 is arranged to guide the cable c led out of the guide passage 13 in a predetermined direction. The cable guide member 21 has a bellows-like duct 23 through which the cable c can be inserted, the connecting portion 7 and the duct. 23 and a connecting member 25 for connecting the connecting member 23 to the connecting member 23. The connecting member 25 is provided with a groove 7a formed in the connecting portion 7.
And an engaging piece 25a that engages with the connecting portion 7 with the elastic deformation of the engaging piece 25a. Further, as shown in the figure, the connection member 25
Both ends in the axial direction are symmetrical, and the duct 23 is connected to the duct 23 on the duct 23 side in the same structure as the connecting portion 7. By the way, the connecting part 7, the duct 23,
The connection members 25 are rectangular cylindrical bodies each having a square shape in the cross section, and can be connected to each other every time the connection members 25 are rotated by 90 degrees about the axis of the cylinder.

The connecting portion 9 has the same configuration as that of the connecting portion 7 except for the arrangement direction, and thus the description thereof is omitted here. Cable wiring tool 1 configured as above
As shown in FIG. 4, when the cable c is laid along the indoor floor, wall, or ceiling, the cable c is attached to the wall W, and the direction of the cable c is set to 90 while holding the cable c. Used to change the degree. When attaching the cable wiring tool 1 to a wall surface or the like, a fixing tool such as a screw or a nail, or an adhesive or a double-sided tape may be used. Although not shown in the figure to clearly show the wiring state of the cable c, usually, the cable c passes through the cable guiding member 21 as shown in FIG. Have been. Further, in FIG. 1, since it is sufficient to know the arrangement direction of the cable wiring tool 1, the detailed shape and the like are simplified.

According to the cable wiring device 1 described above,
The wiring direction of the cable c can be changed by 90 degrees. At this time, the cable c
Will not bend. Therefore, it is suitable especially when laying an optical cable, and even when an optical cable is laid, transmission performance is not degraded or a disconnection is not caused.

Further, since the cable c is accommodated in the annular space 11, for example, unlike a configuration in which cables are wound around a core material, the cable c wound in a loop shape is used.
Are gently held in a state where the loop diameter can be further reduced. Therefore, in a case where the tension applied to the cable c increases due to an external factor, the stress applied to the cable c is reduced by reducing the diameter of the loop. Therefore, even when the optical cable is wired, the cable c is not broken. Also, unlike a configuration in which cables are accommodated in a non-annular space, even if the tension applied to the cable c increases, the diameter of the loop does not become excessively small, so that no bending or the like is caused.

Furthermore, since the connecting portions 7 and 9 are provided outside the case 3, any cable guiding member 21 that can be connected via the connecting member 25 having a specific structure can be easily connected, and the wiring work can be performed. Extremely easy. Next, another case will be described. The cable described in the following example
Since there are many places in the wiring tool which are almost the same as those in the first case described above, only the differences will be described in detail.

[0039] Second case] cabling instrument 31, as shown in FIG. 5, the first instance
Similar to objects, the annular space 33 for accommodating the cable c,
It has guide paths 35 and 37 for guiding both ends c1 and c2 of the accommodated cable c to the outside. However, that the angle of the guide channel 35, 37 is in the 270 degrees, the
It is different from the case of 1 .

The cable wiring device 31 constructed as described above
For example, as shown in FIG. 6, when the cable c is routed at a corner T that bends 90 degrees to be convex, it is attached to the wall surface W. Also in this cable wiring tool 31, the first case
This has the same effect as that of the cable c, and the
If used at the time of changing the angle by 0 degrees, the cable c can be held without being bent, and the cable c is not broken due to a change in tension. Incidentally, if such a corner portion U bent at 90 degrees concave, as shown in the figure, the first case
The cable wiring device 1 described in the above is more suitable.

[ Third Example ] As shown in FIG. 7, the cable wiring tool 41 includes first and second cables.
Similar to the case, the annular space 4 for storing the cable c
3 and guide paths 45, 47 for guiding both ends c1, c2 of the accommodated cable c to the outside. However, it differs from the first and second cases in that the angle formed by the guide passages 45 and 47 is 180 degrees.

The cable wiring tool 41 constructed as described above
For example, as shown in FIG. 8, when the cable c is wired in a wiring path that bends 180 degrees from the front to the back of the panel P, it is used by being attached to the wall surface W. This cable wiring tool 41 also has the same effect as that of the first and second examples. If used when changing the wiring direction of the cable c by 180 degrees, the cable c can be held without bending.
There is no possibility of disconnection of the cable c due to a change in tension.

[ Fourth Example ] As shown in FIGS. 9A and 9B, a cable wiring member 51 is formed in an annular space 53 similarly to the first to third examples.
And the guide paths 55 and 57, and the angle formed by the guide paths 55 and 57 is 90 degrees, which is the same as that of the first case . However, the cable guide 51 is provided on the side walls 61a, 61b of the case 61 with cable guiding pieces 63, 65.
It has.

The cable guide pieces 63 and 65 are movable members connected to the case 61 via hinge portions 63a and 65a.
7 (the position of the cable guiding piece 63 in the figure), while operating the operating pieces 63b and 65b into the case 61 while elastically deforming the hinge portions 63a and 65a. Only, the position moves to the position (the position of the cable guiding piece 65 in the figure) that blocks between the annular space 53 and the guiding passages 55 and 57.

The cable wiring tool 51 constructed as described above
According to this, when introducing and holding the cable inside the cable distribution tool 51, first, the cable guide piece 65 is pushed into the inside as shown in the figure, and then the cable is inserted from the guide passage 55 side in the direction of the arrow D1 in the figure. Then, the distal end of the cable that has advanced along the annular space 53 advances in the illustrated arrow D2 direction while abutting on the cable guide piece 65,
The circuit goes around the annular space 53 once. When the end of the cable reaches the position of the cable guide piece 65 again, the operation piece 6
5b is stopped, and the annular space 53 and the guide passage 57 are stopped.
Then, the end of the cable passes through the guide passage 57 and proceeds in the direction of the arrow D3 in the figure.

Therefore, in the case of an optical cable in which a connector is not attached to the end, the cable can be inserted only from one of the guide paths without removing the lid from the case body and storing the cable. It can be easily introduced into the annular space 53. In addition, even with this cable wiring tool 51, the cable c can be held without being bent,
The effect that the cable c is not broken due to a change in tension is the same as that of the first to third examples .

[ Fifth Example ] As shown in FIG. 10, the cable wiring member 71 includes first and second cables.
Holding portions 73 and 75 are provided. Each of the first and second holding portions 73 and 75 has exactly the same structure as the cable wiring device 1 shown in the first example .
The cable can be curved and held at a predetermined curvature or less, and both ends of the cable are guided in a substantially right-angled wiring direction without being bent beyond the curvature. The first and second holding portions 73 and 75 are connected to the connecting member 25 of the cable guiding member 21 (see FIG. 3) shown in the first example .
The first holding unit 73 changes the wiring direction to a substantially right angle, and the second holding unit 75 connects the wiring in a direction substantially perpendicular to the surface of the first holding unit 73 that includes the wiring direction. It is arranged to change the direction.

The cable wiring member 71 configured as described above
For example, as shown in FIG. 11, the cable c is attached to a wall W or the like when the cable c is routed to a corner T that bends 90 degrees or a corner U that bends 90 degrees. Therefore, even in this cable wiring tool 71, the first case or
As in the case of the second example , the cable c can be held without being bent, and the cable c is not broken due to a change in tension.

In particular, by changing the wiring direction twice by 90 degrees, the cable c forms a loop in a plane parallel to the wiring surface, and the cable c is routed without leaving the wiring surface. The height at which the cable wiring tool 71 protrudes from the wiring surface is determined by the first and second holding portions 73 and 75 (that is,
Only the thickness of the cable wiring device 1) is required. Therefore,
Compared with the case of the first case or the case of the second case , the space in which the cable wiring tool 71 protrudes is reduced, and the dead space can be reduced. Further, since the cable c does not separate from the wiring surface, there is no need to worry about anything caught on the cable c after wiring.

As mentioned above, some specific examples are given.
Although the embodiments of the present invention have been described above, as to the specific configuration of the present invention, various embodiments other than the above-described embodiments may be employed without departing from the spirit of the present invention.
For example, in the fifth case, a cable wiring tool capable of suppressing the protrusion from the wall, in showed two combination examples cabling tool of first instance, inhibit projecting from the wall surface is The point is that the wiring direction is changed by dividing the cable twice by 90 degrees, and in addition to combining two cable wiring tools, a cable having a dedicated structure for performing such wiring Wiring tools may be used. However, in the case of the fifth case , the parts of the first case are used as parts, so if only the case of the first case is manufactured, it can be used in two ways without making a dedicated design product.
There is an industrial advantage.

In the fifth example , the two cable wiring tools of the first example were combined, so that the cables were wound in a loop and stored in each holding portion for changing the wiring direction. Considering only suppression of protrusion from the wall surface, the holding portion does not necessarily need to be wound in a loop shape and held, as long as the holding portion holds it without bending it beyond a predetermined curvature. In particular, in the case of the fifth case , the wiring direction is changed twice internally, so that the first to fourth cases are performed.
Compared to the example , the cable is less likely to shift in the axial direction,
There is no problem even if it is not wound in a loop. However, in order to reduce the stress applied to the cable, it is more advantageous to hold the cable in a loop.

Further, in the fifth case , since the first and second holding portions 73 and 75 are connected via the straight tubular connecting member 25, a part of each of the holding portions 73 and 75 is formed. However, if the first and second holding portions 73 and 75 are connected to each other by a bellows-like duct that is flexibly deformed, the holding portions 73 and 75 protrude from the wall surface. It is possible to attach so that it does not. However, in this case, the positional relationship between the holding portion and the duct is set so that the cables extending from the guiding passage of one holding portion to the guiding passage of the other holding portion do not curve beyond a predetermined curvature in the bellows-like duct. Should be adjusted.

Further, in the embodiment, a structure for connecting the cable wiring member and the cable guiding member has a specific shape. However, various connecting structures for tubular bodies are known. May be applied to any of known connection structures, and is not limited to the embodiment.

In addition, in each of the above cases , the wiring direction is set to 90
Although the example in which the angle is changed by 180 degrees, 180 degrees, and 270 degrees has been described, the wiring direction can be changed to any other angle if necessary. In addition, in the fifth case, the example of connecting two cable wire fitting, the first to fourth that
Each of the examples has a connection portion of the same shape,
Combinations other than the combination shown in the fifth example can be connected to each other via the connection member 25. If Shimese specific examples, as shown in FIG. 12, a cabling device 1 of the first case two and the cable wire fitting 41 of the third case when combined one, as in the fifth case And cable c
The cable c can be wired so as to draw a loop on a plane parallel to the wiring surface, and the protrusion of each cable wiring tool from the wall surface can be suppressed. Moreover, unlike the fifth example , since the height position at which the cable c is arranged does not change with the change in the wiring direction, there is an advantage that wiring can be performed in parallel with the ceiling surface, for example.

In the fifth case , an example is shown in which the cable is wired over the angle formed by the two surfaces using the cable wiring tool of the present invention. However, the present invention can be implemented using other wiring tools. If a specific example is given, the characteristic path | route of Claim 1 is formed using a flexible duct which can be deform | transformed into the shape which forms a desired path | route, and cables etc. are passed through the duct, A large number of clamps capable of gripping cables may be attached at positions along the route to grip the cables. However, in the case of arranging cables for which the allowable maximum curvature is specified, it is determined whether or not the curvature of the cables is equal to or less than the allowable maximum curvature in a curved portion.
Since it is troublesome to check each time at the work site, the cable wiring tool as in each of the above cases is excellent in that the cables can be held at the desired curvature simply by holding them.

[0056]

As described above, according to the cable wiring device of the present invention,
According to this, it is possible to get over the angle between the two planes without bending the cables, so that even if cables such as an optical cable that are weak to be bent are wired in such a place, the transmission performance is reduced. There is no danger of disconnection or disconnection.
