  Japanese Patent Application No. 2006-128676   Patent application filed on February 14, 2007

  The cable duct of Patent Document 1 described above is a hollow body having a substantially rectangular end surface, and is closed at the side where one side overlaps twice, and is extruded with the side overlapping with the square shape slightly opened. In the next process, when cutting or drilling a slit or the like by punching or drilling from the upper surface of the cable duct, the cable duct that is complicated and laborious and takes a long time to cut while opening the cable duct. When the cable is stored in the cable, it is necessary to store the cable duct while pushing the cable duct open, and the storage work is complicated and time-consuming.

  In addition, after the cable is stored, the elasticity of the double overlapping side shape and material is used to hold the cable duct in a closed state, and if this is used to repeatedly bend the cable duct, There is a possibility that the cable may enter into the gap on one side where the cable overlaps due to bending distortion, which may cause the cable core to break, and the branch from the cable duct could not be branched. It was done.

  Since the cable duct can be bent only in one direction, the cable duct is limited to a limited apparatus, and is not versatile. Therefore, there has been a demand for an object that can be bent in the vertical and horizontal directions for general use.

  Furthermore, the connection locking structure for closing the bendable cable duct of Patent Document 2 is substantially the same as that of Patent Document 1 described above, and additional processing such as slits and holes is performed while pushing the cable duct open. It is necessary to store the cable while pushing it open, so additional processing and storage work are complicated and troublesome, and since the bending of the cable duct can only be bent in one direction, it can be easily bent vertically and horizontally There was a need for a product that could be used in the process and further branched on the way.

  In addition, the generally known spiral bundling cable protection member is simple and can be bent in multiple directions, but the work while winding a long cable is very laborious, once it is wound, and additional cables are added. Or, when changing the branch of the cable on the way, it is necessary to unwind it once, and it was not possible to easily change it by a very troublesome work.

  In particular, cables for peripheral devices such as personal computers are extremely troublesome and time-consuming to be stored in cable ducts with bent cables, and in addition to cables with bent cables. The work is troublesome in the fitting work of connecting and locking to close the cable duct because the cable becomes an obstacle, and the work efficiency is poor in common with the above-described conventional example.

  In addition, optical fiber cables for communication, which have been developed in recent years and are being generalized by ordinary households, are thin and easy to disconnect, and may cause a decrease in transmission speed due to cable deformation. In the cable duct, there is a possibility that problems such as disconnection and a decrease in transmission speed may occur. In particular, care should be taken in handling bending and indoor wiring, and it is required to solve these problems. It was.

According to the present invention, as a first solution for effectively achieving the above-described problems, in a manufacturing method for extruding a cable duct, a planar cable plate body having a substantially flat plate shape is connected to both ends thereof. A process of extruding in a shape provided with a locking body;
The bent cut portion for making a bendable cable duct is pressed by manufacturing the bent cut portion at a predetermined position of the extruded sheet cable duct body by a process such as pressing. Can be easily formed.

  Further, as a second solving means, the extruded cable duct is a plate-like cable duct body having a substantially flat plate shape and having connection locking bodies at both ends thereof, and a predetermined position of the plate-like cable duct body. Since the bent cut portion is formed in the main part of the cable, it is easy to store the cable in the cable duct.

  Further, as a third solution, the cable duct formed in a closed state by the connection latching bodies at both ends of the plate-shaped cable duct body can be bent up and down, left and right, or freely bent. A cable duct is formed by forming a bent cut portion at a position corresponding to the up / down / left / right or a free bend and leaving the predetermined portion at a position corresponding to the up / down / left / right or a free bend. Since it can be bent vertically and horizontally or freely, the wiring location can be set freely.

  Further, as a fourth solution, the cable duct formed in a closed state by the connection locking bodies at both ends of the plate-shaped cable duct body, and the surface is cut while being sandwiched between the bending cut portions. By forming a cutting reference portion that is cut in a substantially V shape at a predetermined position on the surface sandwiched between each bent cut portion so that the cable can be branched and taken out, The cable can be bent freely in a predetermined direction while being freely bent.

  Further, as a fifth solution, the cable holding body is provided at a predetermined position inside the cable duct formed in a closed state by the connection locking bodies at both ends of the plate-shaped cable duct body, so that the influence such as disconnection It can be stored together with optical cables that are easily received, and normal cables, and cables with bent hooks can be stored easily.

The present invention is such that an effective effect can be obtained by the above-described means, and in particular, in the production method of the first invention, an olefin resin (PP, PE) having both softness and hardness having deformation recovery ability. In a method of manufacturing a cable duct having a connection locking body by an extrusion molding process and a pressing process using a thermoplastic elastomer in which an olefin rubber (EPR, EPDM) is finely dispersed in a matrix of A step of extruding a planar substantially plate-like plate-shaped cable duct body provided with connection locking bodies at both ends,
Since it is manufactured by a manufacturing method having a process of forming a bent cut portion with a press or the like in a main portion at a predetermined position of the extruded plate-shaped cable duct body,
Since it is extrusion molded as a flat plate-like plate-like cable duct body, it is possible to easily form a folded cut portion for making a cable duct that can be bent in a plate-like state with a press or the like. The work process can be simplified and the cost can be reduced.

Further, in the cable duct of the second invention, a thermoplastic elastomer in which an olefin rubber (EPR, EPDM) is finely dispersed in a matrix of an olefin resin (PP, PE) having both softness and hardness having deformation recovery ability. A cable duct having a connection latching body extruded using a plate-like cable duct body having a substantially flat plate shape and having connection latching bodies at both ends thereof, Since the bent part is formed in the main part of the position,
When storing the cable in the cable duct, the plate-like cable duct body is stored in a flat plate shape so that the cable can be put on it, and it is closed by locking with the connection locking body to complete the storage work. Therefore, the cable storage work is simple and easy, and when the cable is additionally stored or removed, it is cumbersome and time-consuming, as with conventional spiral type cable protectors, and the connection latch is removed to remove the plane. Since it opens in a plate shape, it can be easily stored or removed.

Further, in the plate-like cable duct body of the third invention, the plate is formed so that the cable duct formed in a closed state by the connection locking bodies at both ends of the plate-like cable duct body can be bent up and down, left and right or freely. Forming a bent cut portion at a position corresponding to the upper, lower, left and right of the cable duct body, or a free bend, and forming a bent portion leaving the predetermined portion at a position corresponding to the upper, lower, left and right or a free bend. Because
The cable duct can be bent up and down, left and right, or freely bent depending on the position where the cut-and-cut part is formed. Therefore, when PCs and peripheral devices are placed around the disk, there are few restrictions on the wiring location and the complicated wiring around the PC is clean. Can be organized.

Further, in the plate-like cable duct body according to the fourth invention, the cable duct is formed in a closed state by the connection latching bodies at both ends of the plate-like cable duct body, and is sandwiched between the bent cut portions. Since a cut reference portion cut in a substantially V shape is formed at a predetermined position on the surface between the cut and cut portions so that the surface can be cut off and the cable can be branched out.
Since the cable duct can be bent vertically and horizontally or freely, and the main part of the surface can be cut off from the cut reference portion at a predetermined position, the cable can be branched and taken out from the cut portion, and branch wiring can be easily performed in a predetermined direction.

Further, in the plate-like cable duct body of the fifth invention, a cable holding body is provided at a predetermined position inside the cable duct formed in a state of being closed by connection locking bodies at both ends of the plate-like cable duct body. So
By storing optical cables that are susceptible to disconnection and the like in the cable holder, the cable duct can be easily closed without worrying about it, and it can be stored separately by storing ordinary cables outside the cable holder. When storing cables with bent bends, etc., it is easy to close the cable duct by storing it in the cable holder, and the signal line and power line in the cable duct can be shielded by the holder. It can be mixed with lines that contain noise, and noise countermeasures can be taken.

Further, as a fourth solution, the cable holding body is integrally formed at a predetermined position inside the cable duct that is formed in a closed state by the connection locking bodies at both ends of the plate-like cable duct body of the bendable cable duct. since it provided, housed separately, respectively and susceptible optical cables and cable normally influence such as disconnection, or the like is easily accommodated bending habit with cable.

The present invention is such that an effective effect can be obtained by the above-described means, and in particular, in the production method of the first invention, an olefin resin (PP, PE) having both softness and hardness having deformation recovery ability. In a method of manufacturing a cable duct having a connection locking body by an extrusion molding process and a pressing process using a thermoplastic elastomer in which an olefin rubber (EPR, EPDM) is finely dispersed in a matrix of a step for extruding the respective connection engaging substantially body provided flat plate-shaped plate-like cable duct element in the both end portion,
Since the production of cutouts for folding the main part of the predetermined position of the extrusion molded plate cable duct body in the manufacturing method having a step of forming in a press,
Since it is extrusion molded as a flat plate-like plate-shaped cable duct body, it is possible to easily form a cut-out portion for bending to make a cable duct that can be bent in a plate-like state with a press or the like. The work process can be simplified and the cost can be reduced.

Further, in the cable duct of the second invention, a thermoplastic elastomer in which an olefin rubber (EPR, EPDM) is finely dispersed in a matrix of an olefin resin (PP, PE) having both softness and hardness having deformation recovery ability. in the cable duct having an extrusion molded connection lock body with a plate-like cable duct having a respective connection locking body the both end portions in a plane substantially plate shape, both ends of the plate-like cable duct element In order to allow the cable duct formed in a closed state by the connection locking body of the part to be bent up and down and left and right, a folding cut-out part and a bending part are provided in a predetermined part of the plate-like cable duct body at a predetermined position.

Therefore, the cable storage work is simple and easy, and when the cable is additionally stored or removed, it is cumbersome and time-consuming, as with conventional spiral type cable protectors, and the connection latch is removed to remove the plane. Since it opens in a plate shape, it can be easily stored or removed.

In addition, since the cable duct can be bent vertically and horizontally depending on the position where the cut-out part is formed, there are few restrictions on the wiring place when placing personal computers and peripheral devices around the disk, and complicated wiring around the personal computers. Can be arranged neatly.

Further, in the plate-like cable duct body of the third invention, in the cut-out portion for bending the cable duct formed in a state of being closed by the connection locking bodies at both ends of the plate-like cable duct body of the bendable cable duct It was excised predetermined surface of the cable duct sandwiched, so that the cables can branch taken out to be inserted to form a cut branch port, to the predetermined surface of the bent portion near a root of a given face of the cable ducts Since the cut reference part cut into a substantially V shape from the cut part for bending is formed,
Because both the bending the cable duct in the vertical and horizontal directions can be cut the main part of the surface from the cut-away reference portion of the predetermined position, taken out by branching the cable from the cut portion, branch lines in a predetermined direction can be easily.

Further, in the plate-like cable duct body of the fourth invention, the cable is formed at a predetermined position inside the cable duct formed so as to be closed by the connection locking bodies at both ends of the plate-like cable duct body of the bendable cable duct. Since the holding body is provided integrally ,
By storing optical cables that are susceptible to disconnection and the like in the cable holder, the cable duct can be easily closed without worrying about it, and it is stored separately by storing ordinary cables outside the cable holder. time, by accommodating the cable holding member, closing the cable duct work more readily, signal lines in the cable duct by shielding the holding body and which can be, for housing and further bending habit with cable It can be mixed with noise lines such as power lines, and noise countermeasures can be taken.

Are formed as a lower surface bending cut portion 3, and similarly, the cable duct upper surface portion 1 d is left to be a bent portion, and the other surface side is cut to form an upper surface bending cut portion 4. In addition, either one of the left and right cable duct side portions 1b and 1c is left without being cut, and a bent portion is left. The other side is cut to cut the left side bent portion 5 and the right side bent portion. Each of the portions 6 is formed and the lower surface bending cut portion 3, the upper surface bending cut portion 4, the left side bent cutting portion 5 and the right side bent cutting portion are formed at predetermined intervals in the longitudinal direction of the cable duct 1.

Further, the connection locking body 2 shown in FIG. 2 is formed in substantially the same substantially U-shape on both ends of the cable duct lower surface portion 1a , and is formed at one end so that the U-shapes are opposed to each other. A folded U-shaped locking portion 7 with a step is formed on the extension of the cable duct lower surface 1a, and a folded U-shaped locking portion 7a is formed on the extension at the other end.

  The U-shaped locking portion 7 is formed with a step from one of the substantially U-shaped ends connected to the cable duct lower surface portion 1a, and is substantially U-shaped with the other end portion as an insertion port portion 8. The corner portion of the connecting step is a base end latching portion 9 and the back from the insertion port portion 8 is a guiding portion 10.

  Further, the U-shaped locking portion 7a at the other end is substantially U-shaped connected to the cable duct lower surface portion 1a at the other end, and is formed by adding an angle to the slightly U-shaped state. The U-shaped locking portion 7a is easily inserted into the insertion port portion 8, and the bent portion of the substantially U shape is formed as the contact hooking portion 11, and the U-shaped locking portion is formed from the insertion port portion 8. 7 is engaged and engaged with the base end hooking portion 9.

As shown in FIG. 6, the plate-shaped cable duct body 1 e is closed to form the cable duct 1.

  Therefore, the locking state of the connection locking body 2 when the plate-shaped cable duct body 1e is closed is, first, an angle that is slightly opened to the insertion port portion 8 of the U-shaped locking portion 7 shown in FIG. With the U-shaped locking part 7a attached, the U-shaped locking part is applied by applying force to push in from the direction of arrow A and opening to return to the plate shape of the plate-shaped cable duct body 1e. The U-shaped locking portion 7a is inserted into the guide portion 10 of FIG. 7, the corresponding contact locking portion 11 is brought into contact with the proximal end locking portion 9, and the cable 15 is accommodated as shown in FIG. close.

In this way, by storing the power cable and the signal cable separately in the cable duct 1 f and the holding body 16, complicated wiring can be compactly gathered by the cable duct 1 f alone.

  Further, the connection locking body 2a is formed with a concave locking body 19 at one end of both ends of the cable duct lower surface portions 1a and 1a and a protruding locking body 20 at the other end, respectively. The both ends of the concave shape serve as the insertion port portion 21, the guide holding portion 22 is formed at the back thereof, and the contact latching portion 23 and the tip latching portion 24 are formed at the both concave end portions, respectively. The hooking portion 23 is slightly shorter than the tip hooking portion 24 and formed with a sharpened tip, while the tip hooking portion 24 has a hooking portion formed in a substantially receptacle shape.

  The other protruding locking body 20 has a plate-like guide portion 25 on the distal end side, and locking portions are formed on the upper and lower sides of the base end side. A concave latching portion 26 corresponding to the tip shape is formed so that the latching portion 23 abuts and locks, while the tip latching portion 24 can be latched on the lower side thereof. A base end latching portion 27 corresponding to the shape latching is formed.

  Therefore, the locking state of the connection locking body 2a to be fitted and inserted is first, as shown in FIG. 9, in the insertion port portions 21 at both ends of the concave locking body 19 of the protruding locking body 20. In the state where the guide portion 25 is inserted, a force is applied from the left and right sides of the cable duct side surface portions 1b and 1c so as to compress and shrink the divided cable duct lower surface portions 1a and 1a, thereby the guide holding portion of the concave locking body 19 The guiding portion 25 is inserted into the innermost portion 22, the abutting latching portion 23 is abutted and latched on the concave latching portion 26, and the distal end latching portion 24 is latched on the proximal end latching portion 27.

In both cases, the predetermined cable 15 is branched and taken out .

Thus, the cable duct 1g of the other embodiment shown in FIG. 11 has a configuration substantially the same as that of the fourth invention, and the tubular holding body 16 provided inside the cable duct 1f of FIG. obtained by the Jo, the plate shape, the holding pieces 28,28a in the standing manner from the plane of the plate-like cable duct element 1i, and formed continuously in the longitudinal direction with a predetermined distance, the one holding piece 28a A contact piece 29 formed in an L shape is provided at the tip.

Further, the cable duct 1g of FIG. 11 is formed as a plate-shaped cable duct body 1i that does not form the bent V-groove 12 formed in the plate-shaped cable duct body 1e of the above-described embodiment. The connection locking body 2 when the body 1i is formed into a tubular shape so as to bend uniformly and is connected to the tube and closed is exemplified by the same as described above, and the connection locking body 2a is used. May be.

  Therefore, when the embodiment of the cable duct 1g is used, the cables 15, 15,... Are arranged and stored between the holding pieces 28, 28a of the plate-shaped cable duct body 1i in the opened state, and the holding pieces. 28 and 28a are also stored separately on the outside and closed so that they are rounded as they are, and are connected and latched by the connection locking body 2. At that time, the holding piece 29 is held on the contact piece 29 of the holding piece 28a inside the cable duct 1g. The front ends of 28 are in contact with each other, and the cables 15, 15,...

DESCRIPTION OF SYMBOLS 1, 1f, 1g, 1h Cable duct 1e, 1i Plate-shaped cable duct body 2, 2a Connection latching body 3 Lower surface bending cutting part 4 Upper surface bending cutting part 5 Left side bending cutting part 6 Right side folding Cutting section for bending 13 Cutting reference section 14 Branch port 15 Cable 16 Holding body 28, 28a Holding piece

The present invention relates to a bendable cable duct having a structure for bending a cable duct vertically and horizontally and a connection locking structure for closing the cable duct into a predetermined cylindrical shape .

Conventionally, the bent structure of the cable duct is a structure filed by the present applicant, the end face of which is a hollow body having a substantially rectangular shape, and one side is doubled and closed at that side. After being molded, it is expanded so as to open from the double overlapping part on one side, and is held in a substantially gate-shaped state, and the upper part in that state is punched or drilled. When a cable duct that can be bent in one direction from a substantially straight line formed by additional processing such as opening or cutting is formed, and the cable is stored, the double overlapping sides are exchanged inside and outside and overlapped In addition, there is a method for manufacturing a cable duct that can be bent in one direction by using the elasticity of the shape and material of the side, and the cable duct. (For example, see Patent Document 1)

In addition, the cable duct of the other application filed by the present applicant is formed in a substantially trapezoidal shape with the lower center part opened by extrusion molding and cut the main part in a direction from a substantially straight line to one direction. There is a connection locking structure for closing a bendable cable duct that can be bent and that is formed in a predetermined shape when the cable is stored, with a connection locking structure of the separated portion of the lower side. (For example, see Patent Document 2)

  Furthermore, the structure that protects a freely bendable cable has a generally tubular shape that is formed in a generally known spiral, and can be freely bent by winding it in a spiral shape from above a bundle of cables. Devices that collectively protect cables are often used for wiring of industrial machinery and the like, and are also well known for managing cables for personal computer peripherals.

  Japanese Patent Application No. 2006-128676   Patent application filed on February 14, 2007

  The cable duct of Patent Document 1 described above is a hollow body having a substantially quadrangular end surface and is closed at one side that overlaps with one side, and is extruded with the side that overlaps with the square shape slightly open. In the next process, when cutting or drilling a slit or the like by punching or drilling from the upper surface of the cable duct, the cable duct that is complicated and laborious and takes a long time to cut while opening the cable duct. When the cable is stored in the cable, it is necessary to store the cable duct while pushing the cable duct open, and the storage work is complicated and time-consuming.

  In addition, after the cable is stored, the elasticity of the double overlapping side shape and material is used to hold the cable duct in a closed state, and if this is used to repeatedly bend the cable duct, There is a possibility that the cable may enter into the gap on one side where the cable overlaps due to bending distortion, which may cause the cable core to break, and the branch from the cable duct could not be branched. It was done.

And the bending of the cable duct is limited to a limited device (a guide device such as a cable generally used in a cutting machine or the like) having a sliding device because it can be bent only in one direction from a substantially straight line . There has been a demand for a product that is not versatile and can be used for general purposes by simply bending it vertically and horizontally.

Furthermore, the connection locking structure for closing the bendable cable duct of Patent Document 2 is substantially the same as that of Patent Document 1 described above, and additional processing such as slits and holes is performed while pushing the cable duct open. It is necessary to store the cable while pushing it open.Therefore, additional processing and storage work are complicated and troublesome, and the cable duct can be bent only in one direction from a substantially straight line. There has been a demand for a product that can be bent and used for general purposes and that can be branched on the way.

In addition, the generally known spiral bundling cable protection member is simple and can be bent in multiple directions, but the work while winding a long cable is very laborious, once it is wound, and additional cables are added. Alternatively, when changing the branch of the cable in the middle, it is necessary to unwind the cable until the beginning of winding or the branch point , and the change cannot be easily performed by a very troublesome work.

  In particular, cables for peripheral devices such as personal computers are extremely troublesome and time-consuming to be stored in cable ducts with bent cables, and in addition to cables with bent cables. The work is troublesome in the fitting work of connecting and locking to close the cable duct because the cable becomes an obstacle, and the work efficiency is poor in common with the above-described conventional example.

  In addition, optical fiber cables for communication, which have been developed in recent years and are being generalized by ordinary households, are thin and easy to disconnect, and may cause a decrease in transmission speed due to cable deformation. In the cable duct, there is a possibility that problems such as disconnection and a decrease in transmission speed may occur. In particular, care should be taken in handling bending and indoor wiring, and it is required to solve these problems. It was.

As a first solution for effectively achieving the above-mentioned problems, the present invention provides a substantially cylindrical cable duct by engaging each other with connection locking bodies at both ends of the plate-shaped cable duct body. formed, the connection engagement Tometai is hermetically connected multiplying at least two places of the engaging portion and the contact engaging portion of the connecting locking bodies of the both ends, and connected locking member of the plate-like cable duct element In order to be able to bend the cable duct closed in the up, down, left, and right directions, a cutting part for bending is formed with a predetermined length in a transverse direction from a predetermined position of the plate-shaped cable duct body, and on the extended line, 該折with the any one surface corresponding to the upper and lower surfaces and left and right side surfaces of the tubular cable ducts formed as bent portions are formed continuously at predetermined intervals cutout and bent plate the bent longitudinally The position of the curved part is the same for either one of the top and bottom surfaces and the left and right side surfaces. Since the staggered form, the cable easily accommodated in the cable duct, bends vertically and horizontally so that it can freely set the line location.

Further, as a second solution, when the cable duct formed into a substantially cylindrical shape by being hooked to each other by the connection locking bodies at both ends of the plate-shaped cable duct body, Since the cable holding body is integrally provided at a predetermined position on the inner side, it is stored separately from the optical cable and the normal cable which are easily affected by disconnection or the like, and the cable with the bent hook is stored.

The present invention is such that an effective effect can be obtained by the above-described means. In particular, the first invention is a substantially plate shape extruded by a thermoplastic elastomer having a deformation recovery force, and each of the both ends is provided with a plate-like shape. A plate-shaped cable duct having a connection locking body is formed into a substantially cylindrical cable duct by being hooked with the connection locking bodies at both ends of the plate-shaped cable duct body. Tometai the sealed connection multiplying in at least two places of the engaging portion and the contact engaging portion of the connecting locking bodies of the both ends, and the closed connection lock body of the plate-like cable duct element cable In order to allow the duct to be bent vertically and horizontally, a cutting section for bending is formed with a predetermined length in a transverse direction from a predetermined position of the plate-shaped cable duct body, and on the extended line, a substantially cylindrical cable duct is formed. One side corresponding to the upper and lower surfaces and the left and right sides Formed as curved portion, the position at which the bent portion so as to form successively at predetermined intervals and a bending portion cut portions for the bent longitudinally, similar to any one side of the upper and lower surfaces and left and right side surfaces Are sequentially shifted to
When storing the cable in the cable duct, the plate-shaped cable duct body is stored in the state of a substantially flat plate so that the cable can be put on it, and is closed and stored in a cylindrical shape by locking with the connection locking body. Since the work is completed, the cable storage work is simple and easy, and when the cable is additionally stored or removed, the connection locking body is removed without being troublesome and troublesome like the conventional spiral type cable protector. Since it opens like a plane, it can be easily stored or removed.

  In addition, since the cable duct can be bent vertically and horizontally depending on the position where the cut-out part is formed, there are few restrictions on the wiring place when placing personal computers and peripheral devices around the disk, and complicated wiring around the personal computers. Can be arranged neatly.

Furthermore, when the second invention is formed in the substantially cylindrical shape of the cable duct that is formed into a substantially cylindrical shape by being hooked to each other by the connection locking bodies at the both ends of the plate-shaped cable duct body, Since the cable holder is integrally provided at a predetermined position ,
By storing optical cables that are susceptible to disconnection and the like in the cable holder, the cable duct can be easily closed without worrying about it, and it is stored separately by storing ordinary cables outside the cable holder. time, by accommodating the cable holding member, closing the cable duct work more readily, signal lines in the cable duct by shielding the holding body and which can be, for housing and further bending habit with cable It can be mixed with noise lines such as power lines, and noise countermeasures can be taken.

In addition, since it is extrusion molded as a flat plate-like plate-shaped cable duct body, a cut-out portion for bending to be a bendable cable duct can be easily formed by press cutting. Therefore, the work process can be simplified and the cost can be reduced.

Since it cut the main part of the surface from the cut-away reference portion of the predetermined positions with bending the cable duct vertically and horizontally, taken out by branching the cable from the cut portion, it facilitates branch lines in a predetermined direction of the vertical and horizontal Therefore, the present invention has a remarkable effect in practice.

And the right-side bend cutting part 6 is one pattern. They are formed in repeated continuous as down.

Moreover, as shown in FIG. 3, the connection latching body 2 shown in FIG. 2 is formed in substantially the same substantially U-shape on both ends of the plate-like plate-shaped cable duct body 1e. Jo is to allow negotiations to one another, whereas the distal end folded like a U-shaped locking portion 7 consisting of the extension of the cable duct lower surface portion 1a and stepped on the end side, the tip folded shape on the extension line of the other end The U-shaped locking portions 7a are respectively formed.

The U-shaped locking portion 7 is formed with a step on the extension line of the side end portion of the cable duct lower surface portion 1a , and a predetermined gap is formed between the U-shaped locking portion 7 and its front end portion that is folded back into a substantially U shape near the step portion. to form a gap, and a proximal retaining portion 9 a portion of a corner of the leading step portion so as to form there as an insertion opening 8, it is formed as an induction unit 10 back from the insertion inlet portion 8.
