  Since the inventions according to Patent Documents 1 to 3 are configured as described above, it is not possible to identify each bundle of cable bundles, and it is necessary to use some sort of identification method. Therefore, conventionally, in order to connect the connection source device (or terminal) and the connection destination device (or terminal) correctly, an operator puts a tape or the like on each cable, and a number or the like for identifying the cable on the tape. I was writing by hand. However, this method has a problem that it takes time to work because one tape is attached to each cable and hand writing is performed. Moreover, since the tape cannot be used repeatedly, it leads to an increase in cost and an increase in waste.

  The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to enable an operator to easily specify a wire at a connection destination and to shorten the work time.

  The wire bundle connection support device according to the present invention includes a device main body, in which a plurality of projecting pieces project in a comb-like shape and can accommodate a wire in a housing portion formed between adjacent projecting pieces, and And a lid that opens and closes the tip end side of the projecting piece, and the accommodating portion has a length that is at least twice the diameter of the wire, can accommodate a plurality of wires, and has a width that is less than twice the diameter. The wire rod is movable in the axial direction.

  The wire bundle connection support device according to the present invention includes a disk-shaped device main body that includes a plurality of cutouts formed radially from an outer peripheral surface to store the wire, and is rotatable on the outer peripheral surface of the device main body. And a substantially annular lid that is formed with a wire insertion port that selectively opens any one of the plurality of storage portions with rotation, and the storage portion has a diameter 2 of the wire rod. It has a length more than double and can accommodate a plurality of wires, and has a width less than twice the diameter and is movable in the axial direction.

  According to the present invention, since the width of the accommodating portion that accommodates the wire is set to be equal to or less than twice the diameter of the wire, the connection support instrument is placed along the wire in a state where the wire is stacked in the accommodating portion. Thus, the wire can be moved from the connection source to the connection destination to guide one end of the wire to the connection destination. At this time, since the stacked order does not change, the operator can easily specify the wire at the connection destination. As in the prior art, the work of sticking one tape per cable and the work of handwriting entry become unnecessary, and the work time can be shortened. In addition, since the connection support device can be used repeatedly, cost and waste can be reduced.

Embodiment 1 FIG.
As shown in FIGS. 1 to 4, the connection support device according to the first embodiment is integrally formed of an elastic material (for example, resin), and stores a wire material such as a cable 30. 10 and the lid 20 are connected via a connecting part 21 so as to be opened and closed.

  A plurality of projecting pieces 11 project from the instrument body 10 in a comb-teeth shape, and an accommodating portion 12 is configured by the adjacent projecting pieces 11. The length of the accommodating portion 12, that is, the length from the base portion to the distal end portion of the protruding piece 11 is formed to be twice or more the diameter of the cable 30, and a plurality of cables 30 are stacked in the radial direction in the accommodating portion 12. Can be accommodated. In the illustrated example, the length of the accommodating portion 12 is formed to be about five times the diameter of the cable 30, and a maximum of five cables 30 can be accommodated in one accommodating portion 12. Moreover, the width of the accommodating portion 12, that is, the distance between the adjacent projecting pieces 11 is formed to be twice or less the diameter of the cable 30, so that the order of the cables 30 accommodated so as to be stacked is not changed. In addition, the instrument body 10 can be moved along the cable 30. In the illustrated example, the width of the accommodating portion 12 is formed to be substantially the same as the diameter of the cable 30, and there is a slight gap between the projecting piece 11 and the cable 30 or light contact.

  At the front end side of each of the projecting pieces 11, a retaining portion 13 that protrudes from the cable 30 accommodated in the accommodating portion 12 is projected. The retaining portion 13 may have any shape as long as it protrudes from the projecting piece 11 and engages with the outer peripheral surface of the cable 30. In the case of the illustrated example, a portion where adjacent retaining portions 13 are closest to each other, that is, a portion where the width of the accommodating portion 12 is minimum is set to be equal to or smaller than the diameter of the cable 30. Further, the upper portion of the retaining portion 13 is tapered, and an insertion guide portion 14 for guiding the cable 30 to the housing portion 12 is provided to facilitate insertion when the cable 30 is inserted into the housing portion 12. Further, two escape portions 15 are provided in the instrument main body 10 so as not to hinder the elastic deformation of the protruding pieces 11 located at both ends.

  When the cable 30 is inserted into the housing portion 12, the cable 30 enters the housing portion 12 while pushing and spreading the insertion guide portion 14 and elastically deforming the protruding piece 11 outward. On the contrary, when the cable 30 is pulled out from the housing portion 12, the cable 30 pushes out the retaining portion 13 and elastically deforms the projecting piece 11 outward, and then goes out from the housing portion 12. If a certain force is not applied to the cable 30, the retaining portion 13 cannot be spread out, so that the cable 30 can be prevented from being pulled out.

  In addition, a holding portion 16 is formed in the lower part of the instrument body 10 to be held by a finger when an operator performs the accommodating operation of the cable 30. In addition, the holding unit 16 is formed with a type display unit 17 that serves as a mark for identifying the type (diameter and the like) of the cable 30 that can be stored in the storage unit 12. For example, a connection support device having an open type display portion 17 as shown in the example represents a shape matched to the thin cable 30, and a connection support device (not shown) whose type display portion 17 is closed. ) Represents a shape matched to the thick cable 30. The type may be expressed not only by the presence / absence of the opening of the type display unit 17 but also by a symbol, a figure, or the like. Further, the type display unit 17 may be formed on the lid 20.

  The connecting portion between the lid 20 and the instrument body 10 is formed with a thin and flexible connecting portion 21 so that the lid 20 can be opened and closed with respect to the instrument body 10. In the illustrated example, the connecting portion 21 is also integrally formed when the connection assisting device is resin-molded. However, the present invention is not limited to this, and the device main body 10 and the lid body 20 are separately manufactured and separated by a hinge or the like. You may connect both using a member as the connection part 21. FIG.

  In addition, it is not necessary to comprise the whole connection assistance instrument with an elastic body, and the protrusion 11 should just be comprised with the elastic body. When the projecting piece 11 is elastically deformed, the rigid cable 30 can pass between the retaining portions 13. Alternatively, when the cable 30 is covered with a flexible film, the film of the cable 30 bends and can pass between the retaining portions 13 without the protrusion 11 being elastically deformed. In that case, it is not necessary that the connection support instrument including the projecting piece 11 is an elastic body.

  Locking portions 18 and 22 that lock each other are formed at positions facing each other when the instrument body 10 and the lid 20 are closed. In the vicinity of the locking portion 22 of the lid body 20, a knob portion 23 that projects a finger when the operator opens the lid body 20 is projected. In addition, a plurality of protrusions 24 are formed at portions facing the protruding piece 11 when the lid 20 is closed. These protrusions 24 are respectively fitted between the tips of adjacent protrusions 11 to prevent elastic deformation of each protrusion 11 in the state where the lid 20 is closed.

Next, the operation of the connection support instrument will be described. Here, a case where a connection source device and a connection destination device installed inside a switchboard are connected by a plurality of cables 30 will be described as an example.
(1) The worker connects each of the cables 30 to a predetermined terminal of the connection source device according to a drawing or the like describing the wiring of the switchboard.
(2) Subsequently, the operator inserts the plurality of cables 30 one by one in an arbitrary order into the accommodating portion 12.
(3) When the operator finishes accommodating all of the plurality of cables 30, the operator closes the lid 20 and locks the locking portions 18 and 22. At this time, the connection support instrument is in the state shown in FIGS.

(4) Subsequently, the operator guides the connection support instrument to the vicinity of the connected device while sliding along the cable 30 in one of the directions indicated by the arrows in FIG. Thereby, the one end part of the cable 30 is also guide | induced to a connecting device. During the distribution, the bundle of cables 30 may be bundled at a necessary place, or the bundle of cables 30 may be fixed to an arbitrary place in the switchboard.
(5) Subsequently, the operator pushes up the knob portion 23 with his / her finger to open the lid 20, and pulls out the cables 30 accommodated in the accommodating portion 12 one by one in the order reverse to the insertion order, and the like. To connect to a predetermined terminal of the connection destination device. Alternatively, the cable 30 may be pulled out in the axial direction without opening the lid 20.

  On the other hand, since the conventional binding tools such as Patent Documents 1 to 3 described above hold the cable 30 so as not to move in the axial direction and the radial direction, the binding tool is slid along the cable 30. One end of the cable 30 could not be guided to the connection destination.

  Since the protrusion 11 is thin, the outermost diameter of the bundle of cables 30 accommodated in the connection support device and the outermost bundle of cables 30 that are simply bundled without using the connection support device. The diameter is substantially the same. Therefore, even if it is a place designed according to the outer diameter of the bundle of cables 30 such as a hole through which the bundle of cables 30 is provided in the switchboard, a space for wiring is narrow, and there is little room, It can be routed using a connection aid.

  In addition, a large number of connection support devices may be attached to the cable 30 in advance, assuming that the connection support device has fallen out of the cable 30 when the connection support device is used for the arrangement. . At this time, the insertion order of the cable 30 is the same for each connection support device. Thereby, even if a connection assistance instrument falls out of the cable 30 during the arrangement of the above (4), it can be arranged using the connection assistance instrument that has been preliminarily attached.

  As described above, according to the first embodiment, the connection support instrument can accommodate the cable 30 in the accommodating portion 12 formed between the adjacent projecting pieces 11 with the plurality of projecting pieces 11 projecting in a comb shape. A main body 10 and a lid 20 that opens and closes the distal end side of the projecting piece 11 of the housing portion 12, and the housing portion 12 has a length that is at least twice the diameter of the cable 30 and a plurality of cables 30. The cable 30 is configured to be able to be accommodated and movable in the axial direction with a width less than twice the diameter. For this reason, while moving the connection support device from the connection source to the connection destination, the insertion order of the cables 30 is not changed, and the state in which the insertion order matches the order determined in the drawings or the like can be maintained. Moreover, the cable 30 can be prevented from coming off by closing the lid 20. Therefore, the operator can easily specify the cable 30 at the connection destination. As a result, the work of pasting one tape per cable and the work of handwriting entry as in the prior art become unnecessary, and the work time can be shortened. In addition, since the connection support device can be used repeatedly, cost and waste can be reduced.

  Further, according to the first embodiment, the protruding piece 11 has elasticity, and the stopper 20 is formed at the tip of the protruding piece 11 so as to be locked to the cable 30 and prevent it from coming off. While the cables 30 are being inserted into the housing part 12 one by one in this state, the cables 30 that have already been inserted are unlikely to come off.

  Further, according to the first embodiment, the lid 20 is formed with the protrusion 24 that fits between the adjacent protrusions 11, so the position of the tip end side of the protrusion 11 is fixed, and the cable 30. Even if a large force is applied to the protrusion 11, the protrusion 11 does not elastically deform. For this reason, the effect of preventing the change of the order of the cables 30 accommodated in the accommodating portion 12 can be enhanced.

Moreover, according to Embodiment 1, since the connection assistance instrument was provided with the connection part 21 which connected the instrument main body 10 and the cover body 20 so that opening and closing was possible, loss of the cover body 20 can be prevented.
In addition, it is also possible to comprise the instrument main body 10 and the cover body 20 separately, without providing the connection part 21. FIG. For example, in the illustrated example, when the instrument body 10 and the lid body 20 are configured separately, the same shape as the locking portions 18 and 22 is provided in the portion where the coupling part 21 is originally provided, and both ends of the lid body 20 are connected to the instrument body 10. It only has to be locked to.

Embodiment 2. FIG.
FIG. 5 shows the configuration of the connection support apparatus according to the second embodiment, FIG. 5 (a) is a front view of the state in which the lid 20 is opened, and FIG. 5 (b) is an enlarged view of the protruding piece 11. . 5 that are the same as or equivalent to those in FIG. 1 to FIG.
As shown in FIG. 5, the retaining portion 13 a has a shape in which the tip of one protrusion 11 among the adjacent protrusions 11 is bent in the direction of the other protrusion 11. Further, by making the bending angle θ an acute angle, when the cable 30 (not shown) accommodated in the accommodating portion 12 moves in the extracting direction and comes into contact with the retaining portion 13a, the projecting piece 11 is removed from the outside. It is made difficult to elastically deform. Thereby, when the cable 30 is inserted into the housing portion 12, the already inserted cable 30 is difficult to come off. Note that when the cable 30 is pulled out from the housing portion 12, if it is difficult to pull out the cable 30 by being caught by the retaining portion 13a, the cable 30 may be pulled out in the axial direction.

  Further, a protrusion 24a is formed in accordance with the shape of the gap between the retaining portion 13a and the protruding piece 11 facing it, and the protruding portion 24a is formed between the adjacent protruding pieces 11 when the lid 20 is closed. Is configured to fit.

  As described above, according to the second embodiment, the retaining portion 13a is formed in a shape in which the tip of one projecting piece 11 of the adjacent projecting pieces 11 is bent at an acute angle toward the other projecting piece 11 side. Therefore, the cables 30 that have already been inserted are more difficult to be removed while the cables 30 are being inserted into the housing portion 12 one by one with the lid 20 opened.

Embodiment 3 FIG.
FIG. 6 is a front view showing the configuration of the connection support instrument according to the third embodiment. 6 that are the same as or equivalent to those in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.
As shown in FIG. 6, a concavo-convex shape 40 is formed on the wall surface of the projecting piece 11 so as to contact and position a part of the outer peripheral portion of the cable 30 (not shown). The concave / convex shape 40 includes a convex portion 41 that holds the cable 30 and a concave portion 42 that accommodates and holds the cable 30. What is necessary is just to form the convex part 41 and the recessed part 42 according to the number of the cables 30 accommodated in the accommodating part 12. FIG.

In the case of providing the concavo-convex shape 40, the portion where the adjacent convex portions 41 are closest to each other, that is, the portion where the width of the accommodating portion 12 is the smallest, is accommodated so as to be stacked by being less than twice the diameter of the cable 30. It is possible to prevent the order of the cables 30 from being changed.
The portion where adjacent convex portions 41 are closest to each other may be further narrowed, and when the convex portions 41 are narrower than the diameter and the concave portions 42 are substantially the same as the diameter, as shown in the illustrated example, the cable 30 The change of the order can be completely prevented while allowing the instrument body 10 to be movable along the axis. Even if the distance between the convex portions 41 is narrower than the diameter, the cable 30 can be inserted and removed because the protruding piece 11 is elastically deformed.

  As described above, according to the third embodiment, the wall surface of the projecting piece 11 is formed with the concavo-convex shape 40 that contacts and positions a part of the outer peripheral surface of the cable 30, so that the cables 30 are individually held. The order of the cables 30 is more difficult to change.

Embodiment 4 FIG.
FIG. 7 is a front view showing an example of the configuration of the connection support instrument according to the fourth embodiment. FIG. 8 is an external perspective view showing another example of the configuration of the connection support apparatus according to the fourth embodiment. 7 and 8, the same or corresponding parts as those in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.

  In this Embodiment 4, in order to fix a connection assistance instrument to arbitrary places, such as a switchboard, the fixing | fixed part 50 is formed in the bottom part of the instrument main body 10. FIG. In the example of FIG. 7, the adhesive surface 51 is configured by applying an adhesive tape or applying an adhesive to the bottom surface of the fixed portion 50. In the example of FIG. 8, a screw hole 52 is formed in the fixing portion 50.

Next, the operation of the connection support instrument will be described. Here, as in the first embodiment, a case where a connection source device and a connection destination device installed inside a switchboard are connected by a plurality of cables 30 (not shown) will be described as an example. Furthermore, in this Embodiment 4, a connection assistance instrument is fixed in arbitrary 1 places in a switchboard.
(11) First, the worker performs work in the same manner as (1) to (3) of the first embodiment, and accommodates the plurality of cables 30 in the first connection support instrument.
(12) Subsequently, the operator accommodates the plurality of cables 30 in the second connection support device in the order in which the cables 30 are inserted into the first connection support device. At this time, two connection support devices are attached to the cable 30. It is assumed that the first connection support device is located on the connection source device side and the second connection support device is located on the connection destination device side.

(13) The operator guides the first and second connection support devices as a group to the vicinity of the connection destination device while sliding along the cable 30. Thereby, the one end part of the cable 30 is also guide | induced to a connecting device. During the arrangement, the first connection support device and the cable 30 are fixed by adhering or screwing the fixing portion 50 of the first connection support device to any place in the switchboard.
(14) Subsequently, the operator opens the lid 20 of the second connection support instrument guided to the vicinity of the connection destination device, and the cables 30 accommodated in the accommodating portion 12 are arranged in an order reverse to the insertion order. Pull out one by one and connect it to the specified terminal of the connected device according to the drawing. Alternatively, the cable 30 may be pulled out in the axial direction without opening the lid 20.

  In the above description, two connection support devices are used, and one of them is fixed at an arbitrary place. However, the present invention is not limited to this, and the necessary number of connection support devices is used according to the number of fixed points. do it. As in the first embodiment, a spare connection support device may be attached to the cable 30 assuming that the cable 30 has fallen off from the connection support device during the arrangement.

  As described above, according to the fourth embodiment, the connection support instrument is configured to include the fixing unit 50 that fixes the instrument main body 10 to an arbitrary place. For this reason, in (13), when moving the connection support tool from the connection source to the connection destination, the cable 30 can be routed to an arbitrary route.

  In the above description, the case where the second to fourth embodiments are respectively applied to the configuration shown in the first embodiment has been described. However, the present invention is not limited to this. The configurations from 2 to the fourth embodiment may be appropriately combined.

Embodiment 5 FIG.
In the first to fourth embodiments, the shape in which the protruding piece 11 is protruded in a comb-like shape is illustrated, but the shape is not limited to this shape. In the fifth embodiment, an example in which the protruding pieces 11 are arranged radially will be described. 9 and 10 show a state in which the lid 20 of the connection support apparatus according to Embodiment 5 is opened, and FIGS. 11 and 12 show a state in which the lid 20 is fully closed. FIG. 13 is an exploded perspective view. 9 to 13, the same or corresponding parts as those in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIGS. 9 to 13, the connection support instrument according to the fifth embodiment is assembled with an instrument body 10 and a lid 20 made of an elastic material (for example, resin), and covers the instrument body 10. The body 20 is configured to be rotatable.

  A plurality of notches are radially formed in the disk-shaped instrument body 10, and each notch forms a housing portion 12 that houses the cable 30. A pair of projecting pieces 11 parallel to the side walls are formed on both side walls of the notch, and a retaining portion 13 and an insertion guide portion 14 are formed on the tip side. Further, a gap is provided between the side wall of the notch and the projecting piece 11, and this clearance is used as a relief portion 15 when the projecting piece 11 is elastically deformed. Further, a protrusion fitting portion 60 is formed on a part of the outer peripheral surface of the instrument body 10, and a rotation guide protrusion 61 is formed on the entire outer peripheral surface. In addition, the protrusion fitting part 60 and the some accommodating part 12 are provided in equiangular pitch along an outer peripheral surface.

  The length of the accommodating portion 12 is formed to be twice or more the diameter of the cable 30, and a plurality of cables 30 can be accommodated in the accommodating portion 12 so as to be stacked in the radial direction. In the illustrated example, the length of the accommodating portion 12 is formed to be about four times the diameter of the cable 30, and a maximum of four cables 30 can be accommodated in one accommodating portion 12. Further, the width of the accommodating portion 12 is formed to be twice or less the diameter of the cable 30 so that the order of the cables 30 accommodated so as to be stacked is not changed, and the instrument main body is aligned along the cable 30. 10 is movable. In the illustrated example, the width of the accommodating portion 12 is formed to be substantially the same as the diameter of the cable 30, and there is a slight gap between the projecting piece 11 and the cable 30 or light contact.

  The substantially annular lid 20 has a holding portion 16 and a type display portion 17 formed on the outer peripheral surface thereof. A rotation guide groove 62 that engages with the rotation guide protrusion 61 of the instrument body 10 is recessed in the inner peripheral surface. By engaging the rotation guide protrusion 61 and the rotation guide groove 62, the lid body 20 is rotatably held with respect to the instrument body 10.

  Further, a protrusion fitting portion 60 of the instrument body 10 and a protrusion 63 that fits between the pair of protrusions 11 protrude from the inner peripheral surface of the lid 20. Each time the lid 20 rotates 1/5, the projection 63 fits between the projection fitting portion 60 or the pair of projections 11 of any one of the accommodating portions 12 to position the lid 20 in its position. Hold on. Further, a part of the lid 20 is cut out, and an insertion port 64 for inserting the cable 30 into the housing portion 12 is formed. Each time the lid 20 rotates 1/5, the insertion port 64 selectively opens any one of the accommodating portions 12, and the cable 30 can be inserted. When the insertion port 64 overlaps with the protrusion fitting part 60, all the accommodating parts 12 are closed.

  When inserting the cable 30 into the housing part 12, the operator rotates the lid 20 to move the insertion port 64 to the housing unit 12, and inserts the cable 30 into the housing unit 12 from the insertion port 64. After the housing, the lid 20 is rotated by 1/5 to close the previous housing portion 12 and the adjacent housing portion 12 is opened, and the next cable 30 is inserted into the opened housing portion 12. Similarly to the first embodiment, since the cable 30 is inserted into and removed from the housing portion 12 while elastically deforming the protruding piece 11 outward, the connection support device of the fifth embodiment also applies a certain force to the cable 30. If it is not added, the retaining portion 13 cannot be expanded and the cable 30 can be prevented from being pulled out. In addition, in the fifth embodiment, the lid 20 can be opened and closed for each housing portion 12, and therefore the effect of preventing the cable 30 from being pulled out can be enhanced.

As described above, according to the fifth embodiment, the connection assisting device has the plurality of notches formed radially from the outer peripheral surface to form the accommodating portion 12 that can accommodate the cable 30, and is parallel to the side walls on both side walls of the notch. A disk-shaped instrument body 10 having a pair of projecting pieces 11 formed thereon, and is rotatably attached to the outer peripheral surface of the instrument body 10, and selectively selects any one of the plurality of accommodating portions 12 along with the rotation. A substantially annular lid body 20 formed with an insertion port 64 to be opened, and the accommodating portion 12 has a length that is at least twice the diameter of the cable 30 and can accommodate a plurality of cables 30. The cable 30 has a width less than twice the diameter and is movable in the axial direction of the cable 30. For this reason, as in the first embodiment, the insertion order of the cable 30 is not changed while the connection support device is moved from the connection source to the connection destination, and the insertion order and the order determined in the drawings and the like are matched. Can be maintained. Therefore, the operator can easily specify the cable 30 at the connection destination. As a result, the work of pasting one tape per cable and the work of handwriting entry as in the prior art become unnecessary, and the work time can be shortened. In addition, since the connection support device can be used repeatedly, cost and waste can be reduced.
Furthermore, since the housing part 12 can be individually opened and closed by the rotation of the instrument body 10 and the lid 20, it is possible to prevent the cables 30 already housed in the housing part 12 from coming off even before all the cables 30 have been housed. be able to.

In addition, although illustration is abbreviate | omitted, with respect to the connection assistance instrument shown in the said Embodiment 5, you may combine suitably the retaining part 13a of the said Embodiment 2, and the uneven | corrugated shape 40 of the said Embodiment 3. FIG. .

Embodiment 6 FIG.
In the first to fifth embodiments, the protruding portion 11 having elasticity is provided in the housing portion 12 and the cable 30 can be inserted and removed by elastically deforming the protruding piece 11.

  As shown in FIGS. 14 to 17, in the connection support instrument according to the sixth embodiment, a plurality of notches are formed radially in the disc-like instrument body 10, and the notches are used as the accommodating portions 12. The length of the accommodating portion 12 is formed to be twice or more the diameter of the cable 30, and a plurality of cables 30 can be accommodated in the accommodating portion 12 so as to be stacked in the radial direction. Further, the width of the accommodating portion 12 is formed to be twice or less the diameter of the cable 30 so that the order of the cables 30 accommodated so as to be stacked is not changed, and the instrument main body is aligned along the cable 30. 10 is movable. Further, the opening end portion of the housing portion 12 is formed in a tapered shape to form the insertion guide portion 14, and the cable 30 is easily inserted into the housing portion 12.

As described above, according to the sixth embodiment, the connection support instrument includes a disk-shaped instrument body 10 having a plurality of notches formed radially from the outer peripheral surface to form the accommodating portion 12 that can accommodate the cable 30, and the instrument body. A substantially annular lid body 20 that is rotatably attached to the outer peripheral surface of the main body 10 and is formed with an insertion port 64 that selectively opens any one of the plurality of accommodating portions 12 with rotation. The accommodating portion 12 has a length that is twice or more the diameter of the cable 30 and can accommodate a plurality of cables 30, and has a width that is twice or less the diameter and is movable in the axial direction of the cable 30. Configured to be possible. For this reason, as in the first and fifth embodiments, the insertion order of the cable 30 is not changed while the connection support device is moved from the connection source to the connection destination, and the insertion order and the order determined in the drawings are the same. The matched state can be maintained. Therefore, the operator can easily specify the cable 30 at the connection destination. As a result, the work of pasting one tape per cable and the work of handwriting entry as in the prior art become unnecessary, and the work time can be shortened. In addition, since the connection support device can be used repeatedly, cost and waste can be reduced.
Further, since the housing portion 12 can be individually opened and closed by rotating the instrument body 10 and the lid 20, the cable 30 housed in the housing portion 12 can be prevented from being pulled out even without the protruding piece 11 and the retaining portion 13. can do.

In addition, although illustration is abbreviate | omitted, you may combine suitably the uneven | corrugated shape 40 of the said Embodiment 3 with respect to the connection assistance instrument shown in the said Embodiment 6. FIG.
Moreover, also in the connection assistance instrument shown in the first to fourth embodiments, the projecting piece 11, the retaining portion 13, and the escape portion 15 can be omitted as in the sixth embodiment. However, in the first to fourth embodiments, since the accommodating portions 12 cannot be individually opened and closed, the length of the accommodating portion 12 is extended to prevent the cable 30 already being accommodated during the accommodation of the cable 30 from the bottom portion. It is desirable to increase the distance from to the opening. Thereby, since the distance to the opening of the cable 30 accommodated in the bottom of the accommodating portion 12 is increased, it is difficult to disconnect.

  In addition to the above, within the scope of the invention, the invention of the present application can be freely combined with each embodiment, modified any component of each embodiment, or omitted any component in each embodiment. Is possible.

  As described above, since the connection support apparatus according to the present invention enables routing from the connection source to the connection destination while maintaining the insertion order of the cables, not only the routing of the signal lines such as the switchboard and the control panel, It is suitable for use in various wire arrangements such as a power cable for household electrical equipment and a LAN (Local Area Network) cable.
