Description

  TECHNICAL FIELD The present invention relates to a tilt type cable duct that can fix devices to the outside and has a cable laying portion for laying cables connected to the devices.

  There are countless wirings (hereinafter referred to as “cables”) connected to each device in control panels and switchboards. For example, even a small machine tool has conventionally had a cable of 100 meters or more inside the control panel. It is used. For cable laying, a member commonly called a cable duct is used, but the cable duct used in the conventional control panel installs control equipment in the control panel separately from the duct. It is a structure that should be called a mold. In the case of this structure, as shown in FIG. 13, the input and output terminals t are normally arranged vertically on the device d. Cable ducts h and h are required. In addition, since a minimum of two vertical ducts v and v are required for routing the cables laid in the horizontal cable ducts up and down, the waste of space required for this cannot be ignored. As a result, the vertical and horizontal cable ducts h and v occupy 30 to 40 percent of the area inside the control panel, and the front plate f in front of the cable duct is just a lid, so the front plate surface Becomes dead space.

  In order to eliminate this waste, an improved type that should be called a duct built-in type in which the front plate f is used as a device mounting location has been devised, and an effective use of dead space in the above-described duct separate type has been achieved (FIG. 14). However, since the cable of the device d attached to the front plate f of the duct is drawn into the duct from the opening at the top of the duct, it is indispensable to provide a working gap s between the upper duct and miniaturization or space saving. It is pointed out that there is no big difference from the viewpoint. Furthermore, what is fatal is that the inside of the cable duct cannot be seen to the bottom unless the gap between the upper and lower cable ducts is considerably increased. Although this point is not limited to the duct built-in type, there is a problem because it places a burden on the user in terms of maintenance.

  As the prior art, for example, Japanese Patent Publication No. 53-27480 can be cited. This is an example belonging to the above-described separate duct type, and Japanese Utility Model Publication No. 62-161527 is an example belonging to the duct built-in type. It ’s okay. More recently, there is JP-A-2002-95131, and it is an object to realize a cable duct that does not require an arrangement space for a terminal block. Makes it possible to restore the original state by pushing the cable cover into the cable duct body. However, although a specific configuration for providing the cable cover so as to be able to be pulled out or pushed into the cable body is not shown, a mechanical structure that enables the cable cover to be pulled out and pushed in is required. Also, the cable can only be taken out through the cable cover.

Japanese Patent Publication No.53-27480 Japanese Utility Model Sho 62-161527 JP 2002-95131 A

  The present invention has been made paying attention to the above points, and the problem is that the inside of a limited space such as the inside of the control panel can be used effectively, or the type and size of the device to be used. Is to provide a tilt type cable duct capable of reducing the size of a control panel or the like under the same conditions. Another object of the present invention is to provide a tilt-type cable duct that eliminates the common sense related to the conventional cable duct and enables the cable to be pulled out from anywhere and facilitates the approach to the inside of the cable duct.

In order to solve the above problems, the present invention relates to a cable duct that is capable of fixing devices to the outside and that constitutes a cable laying portion for laying cables that are internally connected to those devices. A front plate having a device attachment means, a bottom plate or an upper plate located behind the lower end or the upper end of the front plate, and a back plate located above or below the rear end of the bottom plate or the upper plate. A duct body is provided, and the front plate is hinged partially or entirely to the duct body so that the cable laying portion can be exposed from the state where the cable laying portion is shielded by the front end portion of the bottom plate or the upper plate. coupled and, in one of at least the upper Symbol bottom plate or the top plate have a cable through a window for the passage of the cable, the upper, lower duct body is connected up and down by the cable through the window Is configured to obtain, in which it took measures that.

  The tilt type cable duct of the present invention having the above-described configuration does not need to have a duct structure having a closed cross section as far as the single duct body is concerned. The duct main body in the example of FIG. 1 described later is a specific example of this configuration, and has a front plate, a bottom plate, and a back plate as described above, and does not have an upper plate. However, even in this configuration, by arranging a plurality of duct bodies in contact with each other (see FIG. 15), the bottom plate of the upper duct also serves as the upper plate of the lower duct, or the upper plate of the lower duct body is It also serves as the bottom plate of the upper duct body, and a cable duct having a closed cross-sectional structure can be configured. As described above, when installing the tilt type cable duct of the present invention, the interval between the adjacent upper and lower duct bodies can be arbitrarily determined, and when arranged most densely, the upper and lower duct bodies are brought into contact with each other. Can be arranged.

  The front plate of the duct body has device attachment means. The device mounting means is generally a DIN rail, but is not limited to the DIN rail. For example, other known mounting means such as direct mounting by screwing may be applied. It is. The upper plate shields the cable laying portion at the front end portion thereof, but a part or all of the upper plate is hinged to the duct body so as to be able to be tilted so that the cable laying portion can be exposed from the shielded state. As the front plate is hinged to the upper plate, the front plate can be rotated around the hinge axis to expose the inside of the duct body. As a result, the cable is drawn out, added, inspected, etc. This makes it easy to check and work on them.

  In the present invention, at least one of the front plate and the upper plate has a cable passage window for passing a cable. A cable pass-through window is a window through which a cable is passed in order to pull out a cable laid in the cable laying section inside the duct body and connect it to a device attached to the front plate via a device attachment means, and is usually arranged vertically It is possible to connect the device to the input and output terminals of the device to be drawn up and down from the inside of the cable laying section. As a result, a minimum of two vertical ducts required for pulling the cable up and down are not required. In addition, detour wiring (loop wiring) that draws a cable loop is not required, and the EMC (Electro-Magnetic Compatibility) risk is proportional to the loop area, so there is a great merit for EMC countermeasures.

  As a duct body in the present invention, a front plate having means for attaching a device, a bottom plate located behind the lower end portion of the front plate, an upper plate located behind the upper end portion of the front plate, and a rear end portion of the bottom plate It is natural to include one having a closed cross-sectional structure, which is located above and below the rear end portion of the upper plate, and is composed of a back plate that connects the rear end portion of the bottom plate and the upper plate. This point is as shown in Example 2 and later described later. And the cable passage window for letting a cable pass can be provided also in the arbitrary board surfaces in a front board, a bottom board, an upper board, and a back board. In the present invention, the window includes a closed opening surrounded by four sides and a notch-shaped opening.

  About the duct body, the end in the cable laying direction is a closed end, the closed end and the slidable side wall are provided at the end of the tiltable front plate, and the front plate is desired In order to fix to the tilt position, it is desirable to provide an engaging portion on the closed end portion and the side wall portion of the front plate. This is because the front plate is fixed at a desired angle set in advance by the engaging portion, and necessary operations relating to the inside of the cable duct main body can be performed in the meantime. In order to fix the front plate of the duct main body at a desired tilt position, a configuration may be adopted in which a receiving support portion is provided that protrudes from an end portion in the cable laying direction and supports the front plate. It is also possible to fix the front plate at the desired tilt position by attaching a member having an arc-shaped long hole along the tilt direction of the front plate to the duct body or front plate and tightening the long hole with a screw. is there.

  When the duct body is made of a metal plate made of iron, aluminum, their respective alloys or other metals, a good electromagnetic shielding effect can be obtained in combination with the sealed structure. By making the duct body made of the above metal plate, the internal cable group is shielded (electromagnetic shielding), which is effective as an EMC countermeasure, and the duct body has higher mechanical strength. However, in the present invention, a duct body made of plastic or plastic and metal composite material can also be used.

  Further, when the duct body is directly connected to a housing such as a cabinet of the control panel by the back plate, the mid plate is not necessary because it itself functions as a middle plate. The intermediate plate is a member indicated by symbol p in FIGS. 13 and 14 and has been indispensable in the past. Further, in an environment where a housing such as a cabinet is unnecessary, the duct body can be held in the equipment machine as it is. As a means for attaching the duct body, a laterally long bolt hole is provided on the back plate, and the position can be adjusted.

  The present invention is configured and operates as described above, and since the interval between the adjacent upper and lower duct bodies can be arbitrarily determined, the inside of the limited space such as the inside of the control panel is effective. In addition, it is possible to provide a tilt type cable duct capable of reducing the size of a control panel or the like under the condition that the device type and size used are the same.

  Further, according to the present invention, common sense related to cable ducts so far can be abolished, a cable passage window for passing a cable through any plate surface can be provided, and a front plate can be installed from any duct body. Since the cable can be pulled out and laid while being tilted, it is possible to provide a tilt-type cable duct that can facilitate the work of pulling out, adding, and inspecting the cable with respect to the cable laying portion, and checking related thereto. .

  Further, according to the present invention, the upper and lower duct bodies can be connected up and down by the cable through window, and the vertical duct that has been conventionally required for connecting the cable ducts at different stages becomes unnecessary. Space in the width direction can be saved by the size of the vertical duct. In addition, it becomes possible to realize EMC countermeasures and grid wiring on the back by eliminating the need for loop wiring.

  In addition, according to the present invention, the efficiency of the cable wiring makes it possible to omit a wiring length exceeding 30% in a trial calculation, and a problem that occurs in proportion to the wiring length, particularly a risk factor due to secular change is remarkable. In addition to being expected to reduce and improve production efficiency, there are many advantages such as reduced check area and misidentification due to downsizing of control panel, etc., reduction of occupied area, change of installation location from indoor to outdoor, etc. For example, in the case of a control panel cabinet or the like, the rigidity (mechanical strength) of the casing is inversely proportional to the cube of the length of the steel plate. Since the rigidity is increased by a factor of nine, if the same rigidity is required, if a 2.3 mm thick steel plate is required, a 1.6 mm thick steel plate of the standard below may be used. 30% reduction in housing weight is realized and material costs are reduced.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. 1 to 5 show Example 1 of a tilt type cable duct according to the present invention. A duct body 10 of Example 1 has a front plate 11, a bottom plate 12 and upper and lower parts of an arbitrary length formed in an elongated shape in the left-right direction. And a short back plate 13. The front plate 11 has device attaching means 14, and is joined at its upper end to the front end of the bottom plate 12 using a hinge member 15, and the bottom plate 12 is formed in a rectangular shape for passing a cable. A plurality of cable passage windows 16 are provided in the longitudinal direction, and an upper end portion of the back plate 13 is located at the rear end portion of the bottom plate 12 so as to be integrated. A plurality of bolt holes 17 formed horizontally are provided in the longitudinal direction (see FIG. 2).

  Although the duct body 10 of Example 1 does not have an upper plate, a space having a substantially rectangular cross section surrounded by the front plate 11, the bottom plate 12 and the back plate 13 is the cable laying portion 18. Further, when the duct body 10 is connected to a casing such as a cabinet of a control panel using the back plate 13 as a duct side attachment portion, the upper duct body 10 and the lower duct body 10 are arranged in contact with each other, thereby arranging the lower body. The bottom plate 12 of the duct main body 10 also serves as the bottom plate of the upper duct main body 10. 1 and 2, reference numeral 19 denotes a support member, which is attached to the left and right ends of the duct body 10 and is screwed with a set screw 11c as necessary in an upright state where the cable laying portion 18 is shielded. It has a female screw hole 11d so that it can be fixed and fixed upright.

  In Example 1 above, the device attachment means 14 is a DIN rail and is formed integrally with the front plate 11. However, it goes without saying that the front plate 11 and the device mounting means 14 which are separately prepared may be formed integrally as in the example described later. Reference numeral 11a denotes a cable passing window, and a plurality of them are provided in the left-right direction of the front plate 11. In the case of Example 1, in order to make the cable laying part 18 exposed from the state of FIG. An open state is taken, and this corresponds to a movement called a forward tilt of the front plate 11. Therefore, in Example 1, it is possible to easily perform checks related to operations such as cable drawing and inspection with respect to the cable laying portion 18 by tilting forward of the front plate 11.

  6 to 8 show Example 2 of the tilt type cable duct according to the present invention. The duct body 20 of Example 2 has a front plate 21, a bottom plate 22, and a back plate having an arbitrary length that is elongated in the left-right direction. A plate 23 and an upper plate 24 are provided. The front plate 21 is divided into two parts above and below a narrow front plate upper portion 21a and a wide front plate lower portion 21b, and hinge members 25a and 25b are used at the front end portion of the bottom plate 22 and the front end portion of the bottom plate 24, respectively. The front plate upper portion 21a is provided with a cut-out cable passage window 26a, and the front plate lower portion 21b is provided with a plurality of cable passage windows 26b that are long in the left-right direction. A plurality of bolt holes 27 are provided in the back plate 23 in the longitudinal direction for adjusting the mounting position.

  In Example 2, the bottom plate 22 and the upper plate 24 are also provided with a plurality of cable passage windows 28 and 29 in the left-right direction, and the cable laying portion inside the duct body is provided from any of the cable passage windows 26a, 26b, 28, and 29. 30. Furthermore, the duct body 20 of Example 2 is a closed end portion 31 in which an end portion in the cable laying direction is closed. Although not shown in the cable duct of Example 2, for example, a female screw portion for screwing can be provided on the front plate 21 as a device attachment means.

  In Example 2, the front plate upper portion 21a and the front plate lower portion 21b are provided with engaging portions 32a and 32b on both sides of the duct body in order to fix them in a desired tilt position. As the engaging portions 32a, 32b, one concave portion or convex portion 33a, 33b is provided at the front end portion of the rotation range around the hinge portion of the front plate upper portion 21a and the front plate lower portion 21b in the closed end portion 31, The front plate upper portion 21a and the front plate lower portion 21b are provided with fan-shaped side wall portions 34a and 34b at the respective left and right end portions, and the side wall portions 34a and 34b are provided with several convex portions or concave portions 35a and 35b. It is configured to be fixed at the open / closed position by the concave-convex engagement between the concave or convex portions 33a and 33b and the convex or concave portions 35a and 35b.

  The front plate upper portion 21a and the front plate lower portion 21b are fixed at desired tilt positions by positioning by the concave and convex engagement between the concave portions or convex portions 33a and 33b and the convex portions or concave portions 35a and 35b. Even if the front plate lower portion 21b and the front plate lower portion 21b are not pressed, it is possible to easily perform checks related to operations such as cable drawing and inspection with respect to the cable laying portion 30. It is ideal that the tilt angle is 90 degrees, that is, a right angle is opened. However, the workability when opened and the conflict with the others are weighed, and the front angle is closed (0 degrees), half-open (30 degrees), and fully opened (60 (Degree).

  FIGS. 9 to 10 show a third example of the tilt type cable duct according to the present invention. In particular, in order to fix the front plate lower portion 41b at a desired tilt position, it protrudes to the end portion in the cable laying direction. This is an example in which a receiving support portion 36 for receiving and supporting the front plate lower portion 41b is provided. Therefore, the duct main body 40 of Example 3 is the same as that of Example 2, and has a front plate 41, a bottom plate 42, a back plate 43, and an upper plate 44, which are elongated in the left-right direction. 41 is divided into two parts above and below a narrow front plate upper portion 41a and a wide front plate lower portion 41b, and is connected to the front end portion of the upper plate 42 and the front end portion of the upper plate 44 using hinge members 45a and 45b, respectively. In addition, the front plate upper portion 41a is provided with a cut-out cable passage window 46a, and the front plate lower portion 41b is provided with a plurality of cable passage windows 46b that are long in the left-right direction. A plurality of bolt through holes 47 are provided in the back plate 43 in the longitudinal direction for adjusting the mounting position. Since the cable passing windows 28 and 29 and the cable laying portion 30 are the same as in Example 2, their reference numerals are used to replace the description.

  The receiving support portion 36 in Example 3 is provided on a projecting piece portion 38 that protrudes forward in the rotational radial direction around the hinge portion at the front end portion of the closed end portion 37 of the duct body 40, and is tilted. The front plate lower portion 41b is received and supported by its lower surface. In the illustrated example, the front plate lower portion 41b is provided to support both sides of the front plate lower portion 41b. Therefore, in Example 3, it is only necessary that the engaging portion 39 by the concave-convex engagement is provided at the positions of the front closing (0 degree) and the half opening (30 degrees). The front plate upper portion 41a in Example 3 is provided with a fan-shaped side wall portion 48 in the same manner as in Example 2, and an engaging portion 49 by concavo-convex engagement is provided between the closed end portion 37 and the side wall portion 48. good. Further, the engaging portions 39 and 49 by the concave-convex engagement may have exactly the same configuration as the concave-convex engagement of the concave portions or convex portions 33a and 33b and the convex portions or concave portions 35a and 35b in Example 2, so the description will not be repeated here. .

  FIG. 11 shows Example 4 in which the DIN rail is attached to the lower part 51b of the front plate 51 as the device attachment means 58 for the tilt type cable duct of Example 2 according to the present invention. The device attachment means 58 is shown as a DIN rail and is attached to the front plate lower portion 51b and the cable passage window is closed. However, it is of course possible to provide the cable passage window in the same manner as in Example 1. Since there is no need to block the front plate upper portion 51a, the cable passing window 26a may be provided in the same manner as in the second and third examples. Since other configurations may be the same as those in the case of Example 2, only the main part will be described. The duct body 50 includes a front plate 51, a bottom plate 52, a back plate 53, and an upper plate 54. The front plate upper portion 51a and the front plate lower portion 51b are hinged to the front end portion of the bottom plate 52 and the front end portion of the upper plate 54, respectively. The members 55a and 55b are used for coupling. The cable through windows 56 and 59 are provided on the bottom plate 52 and the upper plate 54, and a plurality of bolt through holes 57 are provided in the longitudinal direction on the back plate 53 for adjusting the mounting position.

  Further, in Example 4, the front plate upper part 51a and the front plate lower part 51b are provided with engaging portions 64a and 64b on both sides of the duct main body in the same manner as in Example 2 in order to fix them at a desired tilt position. Yes. As the engaging portions 64a and 64b, one concave portion or convex portion 61a and 61b is provided at the front end portion of the rotation range around the hinge portion of the front plate upper portion 51a and the front plate lower portion 51b in the closed end portion 60. The plate upper part 51a and the front plate lower part 51b are provided with fan-shaped side wall parts 62a and 62b at the respective left and right ends, and the side wall parts 62a and 62b are provided with several convex parts or concave parts 63a and 63b. Thus, the concave / convex portions 61a, 61b and the convex / concave portions 63a, 63b are configured to be fixed at the open / closed position by the concave / convex engagement.

  In Examples 2 to 4 described above, the concave / convex engagement is shown as a fixing means for the front plates 21, 41, etc., but for example, as described above, a member having an arc-shaped long hole is attached to the duct body or the front plate. The front plates 21, 41 and the like can be fixed by using a known method such as fixing the front plate at a desired tilt position by tightening a screw through the hole. Further, the support member 19 and the set screw 11c shown in Example 1 can be used to fix the front plates 21, 41, etc. in a state where the duct bodies 20, 40, etc. are closed.

  The tilt type cable duct according to the present invention having such a configuration is shown in FIG. 12 with reference numerals A, A ′, A ″, for example. Can be directly connected (without the need for an intermediate plate) by using fixing means such as bolts 65 and nuts 66. The upper and lower tilt type cable ducts A, A '. Can be selected arbitrarily, both wide and narrow.As shown in the lower part of Fig. 12, the tilt type cable ducts A, A '. The front plate 51b can be opened at a desired angle, and the cable 68 laid inside the cable laying portion 30 can be pulled out, inspected, etc., and can be freely checked.

  The tilt type cable duct according to the present invention can be arranged with the duct bodies 10 in contact with each other so that the device 67 does not get in the way (see FIG. 15). In FIG. 15, the dual-purpose ducts are tilt type cable ducts A, A ′, A ″ according to the present invention. A device 67 is attached to each front plate 11, and each wiring 69 a, 69 b is connected from the cable 68 to the front plate 11. Are drawn out through the cable through windows 11a and 11b and connected to the device 67. Fig. 15 shows a state in which the space-saving effect of the present invention is maximized, but Figs. As apparent from a comparison between the outer dimensions of the cabinet 70 shown with the same dimensions and the interior of the tilt cable ducts A, A ′, A ″, according to the present invention, the front area of the interior of the conventional cabinet is 50 percent. It turns out that it can reduce below.

  In this type of cable duct, it can be said that it has been common knowledge so far to have a closed cross-sectional structure and not to have a tilting structure like the front plate in the present invention. On the other hand, the fact that the tilt type cable duct according to the present invention has a tilt type opening and closing structure is a challenge to the common sense so far, but as a result, it is limited to the inside of the control panel. By effectively utilizing the interior of the space, it is possible to reduce the size of the cable, and the total cable length is significantly shortened by a breakthrough change in the cable pulling path, reducing the material cost, reducing the failure rate, making maintenance easier, Many advantages can be expected, such as a wider installation area.
