Description

この発明は、曲げ方向自在バスダクトに係り、特に、ダクト位置を微調整可能な曲げ方向自在バスダクトに関する。   The present invention relates to a bendable bus duct, and more particularly to a bendable bus duct whose duct position can be finely adjusted.

バスダクトは、銅やアルミニウムなどの金属導体を絶縁物で被覆するか、絶縁物で支持し、金属製のダクトに収納したものである。本来、バスダクトは配置を微調整できる構造ではない。そのため、配電盤、分電盤、変圧器等の更新や改造でダクト位置がずれてしまう場合は、取合い(部材の組み合わせや接続部分)位置が合うように都度検討、設計されている。   The bus duct is a metal conductor such as copper or aluminum covered with an insulator or supported by an insulator and housed in a metal duct. Originally, the bus duct is not a structure in which the arrangement can be finely adjusted. Therefore, when the duct position shifts due to the renewal or modification of the switchboard, distribution board, transformer, etc., it has been studied and designed so that the position (combination of members or connection part) is matched.

ダクト位置の調整を容易にするための構成として、特開平6−13335号公報(特許文献1)には、直線状バスダクト間を可撓性構造体で連結した構成が開示されている。この可撓性構造体は、両側のバスダクトからそれぞれ伸びる可動板を重ねてボルトで連結することで、ボルトを曲げ軸としてバスダクトの角度を可変にする。   As a configuration for facilitating the adjustment of the duct position, Japanese Patent Laid-Open No. 6-13335 (Patent Document 1) discloses a configuration in which linear bus ducts are connected by a flexible structure. In this flexible structure, movable plates extending from the bus ducts on both sides are overlapped and connected with bolts, whereby the angle of the bus duct is made variable with the bolt as a bending axis.

特開平6−13335号公報JP-A-6-13335

しかしながら、上記特許文献1の構成では、ボルトが曲げ軸となるためバスダクトの可変方向が一定方向に制限されてしまい、他の方向についてはダクト位置を調整できない。そのため、ダクト位置の微調整に十分とはいえない。   However, in the configuration of Patent Document 1, since the bolt serves as a bending axis, the variable direction of the bus duct is limited to a certain direction, and the duct position cannot be adjusted in other directions. Therefore, it cannot be said that it is sufficient for fine adjustment of the duct position.

この発明は、上述のような課題を解決するためになされたもので、取合い位置が合うようにダクト位置を微調整可能な曲げ方向自在バスダクトを提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bendable universal bus duct in which the duct position can be finely adjusted so that the fitting position matches.

この発明は、上記の目的を達成するため、曲げ方向自在バスダクトであって、
筒状の第1ダクトと、前記第1ダクトの内部空間に配置される板状の第1金属導体とを有する第1バスダクトと、
筒状の第2ダクトと、前記第2ダクトの内部空間に配置される板状の第2金属導体とを有する第2バスダクトと、
前記第1ダクトの開口部と前記第2ダクトの開口部とを連結する筒状の可撓性カバーと、前記第1金属導体と前記第2金属導体とを接続する可撓性導体とを有するバスダクト連結部と、を備え、
前記可撓性カバーの内部空間において、前記可撓性導体は、前記第1バスダクトと前記第2バスダクトを接続する部材のうち最も可撓性の高い部材であることを特徴とする。
In order to achieve the above-mentioned object, the present invention is a bending direction universal bus duct,
A first bus duct having a cylindrical first duct and a plate-like first metal conductor disposed in the internal space of the first duct;
A second bus duct having a cylindrical second duct and a plate-like second metal conductor disposed in the internal space of the second duct;
A cylindrical flexible cover that connects the opening of the first duct and the opening of the second duct, and a flexible conductor that connects the first metal conductor and the second metal conductor. A bus duct connecting portion,
In the internal space of the flexible cover, the flexible conductor is a member having the highest flexibility among members connecting the first bus duct and the second bus duct.

好ましくは、前記第1バスダクト又は前記第2バスダクトと同構成のバスダクトと、前記バスダクト連結部と同構成の連結部が交互に連結されていること、を特徴とする。   Preferably, the bus duct having the same configuration as the first bus duct or the second bus duct and the connecting portion having the same configuration as the bus duct connecting portion are alternately connected.

この発明によれば、第1バスダクトと第2バスダクトとに方向自在に角度をつけることができる。また、バスダクトとバスダクト連結部を交互に連結することで、ダクトの向きを360度の可動範囲で調整することが可能となる。そのため、本発明によれば、取合い位置が合うようにダクト位置を微調整することができる。その結果、ダクト位置を合わせるための改造作業が不要となり、ダクト改造に関する費用を削減することができる。   According to the present invention, the first bus duct and the second bus duct can be angled freely. Further, by alternately connecting the bus duct and the bus duct connecting portion, the direction of the duct can be adjusted within a movable range of 360 degrees. Therefore, according to the present invention, the duct position can be finely adjusted so that the fitting position is matched. As a result, the modification work for aligning the duct position becomes unnecessary, and the cost related to duct modification can be reduced.

実施の形態1.
[実施の形態1のシステム構成]
図1は、本発明の実施の形態1に係る曲げ方向自在バスダクトの内部構造を示す図である。図1に示すように、バスダクト1Aとバスダクト1Bはバスダクト連結部2により連結されている。
Embodiment 1 FIG.
[System Configuration of Embodiment 1]
FIG. 1 is a diagram showing an internal structure of a bendable universal bus duct according to Embodiment 1 of the present invention. As shown in FIG. 1, the bus duct 1 </ b> A and the bus duct 1 </ b> B are connected by a bus duct connecting portion 2.

(バスダクト1A、バスダクト1B)
バスダクト1Aは、ダクト3A、金属導体4A、支持部材5Aを備える。ダクト3Aは筒状体であり、例えば金属製の角筒である。
(Bus duct 1A, Bus duct 1B)
The bus duct 1A includes a duct 3A, a metal conductor 4A, and a support member 5A. The duct 3A is a cylindrical body, for example, a metal square tube.

金属導体4Aは、ダクト3Aの内部空間に配置される。金属導体4Aは、板状体であり、例えば矩形板である。金属導体4Aの材質は、例えば銅またはアルミニウムである。金属導体4Aは、絶縁体で被膜されている場合もある。   The metal conductor 4A is disposed in the internal space of the duct 3A. The metal conductor 4A is a plate-like body, for example, a rectangular plate. The material of the metal conductor 4A is, for example, copper or aluminum. The metal conductor 4A may be coated with an insulator.

支持部材5Aは、金属導体4Aを支持し、ダクト3Aの内部空間における金属導体4Aの位置を固定する。支持部材5Aは絶縁体であり、例えば碍子である。   The support member 5A supports the metal conductor 4A and fixes the position of the metal conductor 4A in the internal space of the duct 3A. The support member 5A is an insulator, for example, an insulator.

バスダクト1Bは、バスダクト1Aと同様にダクト3B、金属導体4B、支持部材5Bを備える。ダクト3B、金属導体4B、支持部材5Bの構成は、上述のダクト3A、金属導体4A、支持部材5Aと同様であるため説明は省略する。   The bus duct 1B includes a duct 3B, a metal conductor 4B, and a support member 5B, similarly to the bus duct 1A. Since the configurations of the duct 3B, the metal conductor 4B, and the support member 5B are the same as those of the above-described duct 3A, metal conductor 4A, and support member 5A, description thereof is omitted.

(バスダクト連結部2)
バスダクト連結部2は、可撓性カバー6、可撓性導体7を少なくとも備える。可撓性カバー6は、ダクト3Aの開口部とダクト3Bの開口部とを連結する。可撓性カバー6は、筒状体であり、可撓性導体7よりも柔軟性の高い素材(例えばゴム素材)で構成された部材である。
(Bus duct connection part 2)
The bus duct connecting portion 2 includes at least a flexible cover 6 and a flexible conductor 7. The flexible cover 6 connects the opening of the duct 3A and the opening of the duct 3B. The flexible cover 6 is a cylindrical body and is a member made of a material (for example, a rubber material) having higher flexibility than the flexible conductor 7.

可撓性カバー6の内部空間には、金属導体4A及び金属導体4Bよりも可撓性が高い可撓性導体(フレキシブル導体)7が配置されている。可撓性導体7として、金属製の編組線(例えば平編組線)が用いられる。可撓性導体7の両端部は、ボルト及びナット等の締結具により金属導体4Aの端部および金属導体4Bの端部に締結される。   In the internal space of the flexible cover 6, a flexible conductor (flexible conductor) 7 having higher flexibility than the metal conductor 4A and the metal conductor 4B is disposed. As the flexible conductor 7, a metal braided wire (for example, a flat braided wire) is used. Both end portions of the flexible conductor 7 are fastened to the end portions of the metal conductor 4A and the end portions of the metal conductor 4B by fasteners such as bolts and nuts.

可撓性カバー6の内部空間において、可撓性導体7は、バスダクト1Aとバスダクト1Bとを接続する部材のうち最も可撓性の高い部材である。可撓性カバー6の内部空間に配置される部材は、可撓性導体7のみであってもよい。なお、可撓性導体7よりも柔軟性の高い(たわみやすい)他の部材によって、バスダクト1Aとバスダクト1Bとが接続されていてもよい。   In the internal space of the flexible cover 6, the flexible conductor 7 is a member having the highest flexibility among the members connecting the bus duct 1 </ b> A and the bus duct 1 </ b> B. The member disposed in the internal space of the flexible cover 6 may be only the flexible conductor 7. Note that the bus duct 1A and the bus duct 1B may be connected to each other by another member having higher flexibility (easy to bend) than the flexible conductor 7.

図2は、本発明の実施の形態1に係る曲げ方向自在バスダクトを蛇腹状に複数繋げた構成を示す立体図である。バスダクト1A又はバスダクト1Bと同構成のバスダクトと、バスダクト連結部2と同構成の連結部とが交互に連結されることで、図2の立体図のような構成が可能である。   FIG. 2 is a three-dimensional view showing a configuration in which a plurality of bendable bus ducts according to Embodiment 1 of the present invention are connected in a bellows shape. A bus duct having the same configuration as that of the bus duct 1A or the bus duct 1B and a connecting portion having the same configuration as that of the bus duct connecting portion 2 are alternately connected, so that the configuration shown in the three-dimensional view of FIG.

(効果)
以上説明した図1に示す構成によれば、バスダクト1Aとバスダクト1Bとに方向自在に角度をつけることができる。すなわち、ダクトを上下左右に動かすことができる。また、ダクトを所定の角度範囲で回転させることもできる。図2に示す連結構成によれば、ダクトの向きを360度の可動範囲で調整することが可能となる。このように、本発明の実施の形態1に係る曲げ方向自在バスダクトによれば、取合い位置が合うようにダクト位置を微調整することができる。そのため、配電盤、分電盤、変圧器等の更新や改造でダクト位置がずれてしまう場合であっても、ダクト位置を合わせるための改造作業が不要となり、ダクト改造に関する費用を削減することができる。
(effect)
According to the configuration shown in FIG. 1 described above, the bus duct 1A and the bus duct 1B can be angled freely. That is, the duct can be moved up, down, left and right. Further, the duct can be rotated within a predetermined angle range. According to the connection configuration shown in FIG. 2, the direction of the duct can be adjusted within a movable range of 360 degrees. Thus, according to the bendable universal bus duct according to the first embodiment of the present invention, the duct position can be finely adjusted so that the fitting positions are matched. Therefore, even if the duct position is shifted due to the renewal or modification of the switchboard, distribution board, transformer, etc., the modification work for adjusting the duct position becomes unnecessary, and the cost related to the duct modification can be reduced. .

(変形例)
ところで、上述した図1においては、1つのダクト内に金属導体は1枚のみ描かれているが、金属導体の枚数はこれに限定されるものではない。例えば、1つのダクト内に複数枚の金属導体が並列に配置されてもよい(例えば、3線式や4線式のバスダクト)。この場合、バスダクト1A内の各金属導体とバスダクト1B内の各金属導体は、1対1の関係で可撓性導体により接続される。すなわち、バスダクト連結部2内には、複数枚の可撓性導体が並列に配置される。なお、この点は以下の実施の形態でも同様である。
(Modification)
Incidentally, in FIG. 1 described above, only one metal conductor is drawn in one duct, but the number of metal conductors is not limited to this. For example, a plurality of metal conductors may be arranged in parallel in one duct (for example, a 3-wire or 4-wire bus duct). In this case, each metal conductor in the bus duct 1A and each metal conductor in the bus duct 1B are connected by a flexible conductor in a one-to-one relationship. That is, a plurality of flexible conductors are arranged in parallel in the bus duct connecting portion 2. This point is the same in the following embodiments.

実施の形態2.
次に、図3を参照して本発明の実施の形態2について説明する。図3は、本発明の実施の形態2に係る曲げ方向自在バスダクトの内部構造を示す図である。図3に示す構成は、複数の金属導体(7a〜7c)を除き図1と同様であるためその説明を省略する。
Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a diagram showing an internal structure of a bendable universal bus duct according to Embodiment 2 of the present invention. Since the configuration shown in FIG. 3 is the same as that of FIG. 1 except for the plurality of metal conductors (7a to 7c), the description thereof is omitted.

上述した実施の形態1では、実施の形態1では、可撓性導体7として金属導体4Aおよび金属導体4Bの板幅に近い平編組線を用いている。これに対して、実施の形態2に係る曲げ方向自在バスダクトでは、可撓性導体7は、金属導体4Aと金属導体4Bとを接続する複数の金属導体(7a〜7c)(例えば、複数の編組線)により構成される。複数の金属導体のそれぞれは、金属導体4Aおよび金属導体4Bの板幅よりも幅が小さく、間隔を空けて配置されている。   In Embodiment 1 described above, in Embodiment 1, a flat braided wire close to the plate width of the metal conductor 4A and the metal conductor 4B is used as the flexible conductor 7. On the other hand, in the bendable universal bus duct according to the second embodiment, the flexible conductor 7 includes a plurality of metal conductors (7a to 7c) (for example, a plurality of braids) that connect the metal conductor 4A and the metal conductor 4B. Line). Each of the plurality of metal conductors has a width smaller than the plate width of the metal conductor 4A and the metal conductor 4B, and is arranged with an interval.

以上説明した図3に示す構成によれば、実施の形態1に係る曲げ方向自在バスダクトに比して、さらに図3の上下方向への可撓性が高まる。また、実施の形態1と同様の効果を得ることができる。   According to the configuration shown in FIG. 3 described above, the flexibility in the vertical direction in FIG. 3 is further enhanced as compared with the bendable universal bus duct according to the first embodiment. Moreover, the same effect as Embodiment 1 can be acquired.
