Description

本発明は、互いに直角方向に布設されるバスダクト同士を、その離間距離を寸法調整しながら接続可能なＬ字型寸法調整用バスダクトユニットに関するものである。   The present invention relates to an L-shaped dimension adjusting bus duct unit capable of connecting bus ducts laid in a direction perpendicular to each other while adjusting the distance between the ducts.

従来、水平方向に直角に曲がる部分を有するバスダクトを接続する場合には、例えば特許文献１に開示されているような水平曲りバスダクトなるものを用いていた。
特許文献１に開示されている水平曲りバスダクトを図５に示す。図５が示すようにこの水平曲りバスダクト３０は、その内部に板状の導体２ａを絶縁被覆した複数本の絶縁被覆導体２が設けられ、中央の直線部にあってはこれら複数の絶縁被覆導体２が積層され、金属製のハウジング６に覆われている。
そして一方の端部にあっては、絶縁被覆導体２の先端部が隣接する絶縁被覆導体２間に所定の間隔を持たせるように拡げられた拡開段部４が設けられ、各絶縁被覆導体２の先端の絶縁被覆が必要長剥ぎ取られて接続部３５が形成されている。ここで符号３６はダクト側板を示している。 Conventionally, when connecting a bus duct having a portion that bends at right angles to the horizontal direction, a horizontally bent bus duct as disclosed in Patent Document 1 has been used.
A horizontal curved bus duct disclosed in Patent Document 1 is shown in FIG. As shown in FIG. 5, the horizontal bend bus duct 30 is provided with a plurality of insulation-coated conductors 2 in which a plate-like conductor 2a is insulation-coated. 2 are stacked and covered with a metal housing 6.
At one end, an expanded step 4 is provided in which the tip of the insulating coated conductor 2 is widened so as to have a predetermined interval between the adjacent insulating coated conductors 2. The connection coating 35 is formed by stripping off the required length of the insulation coating at the tip of 2. Reference numeral 36 denotes a duct side plate.

また他方の端部に延びる絶縁被覆導体２は、その端部で段差的に直角に折り曲げられて曲り部３７が設けられ、その先端で絶縁被覆が必要長剥ぎ取られて接続部３８が形成されている。ここで符号３９ａ、３９ｂはそれぞれ曲がり部３７の内側、外側に設けられた内側Ｌ型折曲ダクト側板、外側Ｌ型折曲ダクト側板を示している。   Further, the insulating coated conductor 2 extending to the other end is bent at a step at a right angle to form a bent portion 37, and the insulating coating is stripped off at the tip to form a connection portion 38. ing. Here, reference numerals 39a and 39b respectively denote an inner L-shaped bent duct side plate and an outer L-shaped bent duct side plate provided inside and outside the bent portion 37, respectively.

図５が示す特許文献１に開示された水平曲りバスダクト３０の場合、形成が難しい拡開段部４を一方の端部にのみ形成するだけで、その両端部に標準のバスダクトを接続できる利点がある。   In the case of the horizontal bend bus duct 30 disclosed in Patent Document 1 shown in FIG. 5, there is an advantage that a standard bus duct can be connected to both ends only by forming the expanded step portion 4 that is difficult to form only at one end. is there.

ところでバスダクトを工場内等に布設する場合、既存の柱や排気ダクト等障害物を避けながら布設しなければならないため、通常、いずれかの接続個所で離間する２つのバスダクト間の寸法調整が必要になる。
そこで、例えば前記特許文献１記載の水平曲りバスダクト３０を用いて水平曲り部を形成しながら２つの方向の寸法調整を行おうとすると、図６が示すように水平曲りバスダクト３０の両端に寸法調整用バスダクトユニット４０、４０を各々接続する必要がある。 By the way, when laying bus ducts in factories, etc., it is necessary to lay while avoiding obstacles such as existing pillars and exhaust ducts, so it is usually necessary to adjust the dimensions between two bus ducts that are separated from each other at any connection point. Become.
Therefore, for example, when the horizontal curve bus duct 30 described in Patent Document 1 is used to adjust the dimensions in two directions while forming the horizontal curve portion, the dimensions are adjusted at both ends of the horizontal curve bus duct 30 as shown in FIG. It is necessary to connect the bus duct units 40 and 40 respectively.

この寸法調整用バスダクトユニット４０としては、例えば図７が示すようなものがあり、この寸法調整用バスダクトユニット４０を離間距離を有する標準のバスダクト間に寸法調整用として挿入する。
この寸法調整用バスダクトユニット４０の一例としては、例えば銅やアルミニウム製の薄板を積層して形成され、その両端に端子５ａ、５ａを有する複数本の可撓性導体５と、この複数の可撓性導体５の両端に各々接続され、かつその外側をハウジング６で覆われている絶縁被覆導体２と、前記可撓性導体５や可撓性導体５と絶縁被覆導体２の接続部とを覆い、かつハウジング６に各々固定されている箱体４３と箱体４４とからなっている。
因みに可撓性導体５の長さは、接続される標準の２つのバスダクトの離間距離が、設計上最大になると予想される長さに対応できる長さに設定されている。
他方箱体４３と箱体４４は、箱体４４の端部が箱体４３の端部内側に内接状態でスライド可能になっていて、両箱体４３、４４とで構成される箱体全体の長さ方向の寸法、すなわち図７に向かって水平方向、つまりは左右方向の寸法が調整可能になっている。
より具体的に説明すると、箱体４３の端部の箱体４４の端部と重なる部分には、図７に向かって左右方向に長孔４５が設けられており、他方箱体４４には、この長孔４５に対応してネジ孔が形成されていて、長孔４５の長さの範囲内の所定位置で箱体４３と箱体４４とがボルト４６を介して固定されるようになっている。ここで符号４７は必要により使用されるワッシャである。
因みに箱体４３の長孔４５の長さ、及びその形成位置は、前述した可撓性導体５の長さと同様に、接続される両バスダクトの離間距離が最大になると予想される長さにも対応できるように設計されている。 FIG. 7 shows an example of the dimension adjusting bus duct unit 40. The dimension adjusting bus duct unit 40 is inserted between standard bus ducts having a separation distance for dimension adjustment.
As an example of the bus duct unit 40 for dimension adjustment, for example, a plurality of flexible conductors 5 formed by laminating thin plates made of copper or aluminum and having terminals 5a and 5a at both ends thereof, and the plurality of flexible conductors are provided. Covering the insulating coated conductor 2 connected to both ends of the conductive conductor 5 and having the outside covered with the housing 6, and the flexible conductor 5 and the connecting portion of the flexible conductor 5 and the insulating coated conductor 2. And a box body 43 and a box body 44 each fixed to the housing 6.
Incidentally, the length of the flexible conductor 5 is set to a length corresponding to a length in which the distance between two standard bus ducts to be connected is expected to be the maximum in design.
On the other hand, the box body 43 and the box body 44 are configured such that the end of the box body 44 is slidable inside the end of the box body 43 in an inscribed state. The dimension in the length direction, that is, the dimension in the horizontal direction, that is, in the left-right direction toward FIG. 7, can be adjusted.
More specifically, an elongated hole 45 is provided in the left and right direction toward the end of the box 44 at the end of the box 43 in the left-right direction toward FIG. Screw holes are formed corresponding to the long holes 45, and the box 43 and the box 44 are fixed via bolts 46 at predetermined positions within the length of the long holes 45. Yes. Here, reference numeral 47 is a washer used as necessary.
Incidentally, the length of the long hole 45 of the box body 43 and the formation position thereof are the same as the length of the flexible conductor 5 described above, and the length at which the distance between the two bus ducts to be connected is expected to be maximized. It is designed to be compatible.

このような寸法調整用バスダクトユニット４０を離間し対向している２つのバスダクト間に装着する場合には、まず箱体４３と箱体４４とを固定するボルト４６を緩めて箱体４３と箱体４４とが内接状態で互いにスライド可能な状態にする。その上で、箱体４３、４４の両端外部に突出している各絶縁被覆電線２の導体２ａからなる接続部３５と図示していない標準のバスダクトの導体２ａ間との接続を行う。この接続を行っている間に可撓性導体５が両バスダクト間の離間距離に対応して撓み、またこれに伴なって箱体４３と箱体４４とが内接状態でスライドして、離間距離の寸法調整が行われる。すなわち接続される両バスダクト間の離間距離が狭ければ狭いほど、可撓性導体５がより撓み、箱体同士の重なり量が大きくなってバスダクト間の離間距離の寸法調整が行われる。
このように可撓性導体５の撓み量の変化と、これに伴なう箱体同士の重なり量の変化により両バスダクト間の離間距離の寸法調整が行われたら、最後に箱体４３と箱体４４とを長孔４５の部分で箱体４４に設けられているネジ孔にボルト４６をワッシャ４７等を介して締め込めば、対向する標準のバスダクト間への寸法調整用バスダクトユニット４０の装着が完了する。 When such a dimension adjusting bus duct unit 40 is mounted between two bus ducts that are separated and opposed to each other, first, the bolt 46 that fixes the box 43 and the box 44 is loosened to loosen the box 43 and the box. 44 and slidable with each other in an inscribed state. Then, connection is made between the connection portion 35 made of the conductor 2a of each insulation-coated electric wire 2 projecting outside both ends of the box bodies 43 and 44 and the conductor 2a of a standard bus duct (not shown). During this connection, the flexible conductor 5 bends corresponding to the separation distance between the two bus ducts, and the box body 43 and the box body 44 slide in the inscribed state along with this, so that they are separated from each other. The distance is adjusted. That is, the narrower the distance between the two bus ducts that are connected, the more the flexible conductor 5 bends, and the amount of overlap between the boxes increases, so that the dimension of the distance between the bus ducts is adjusted.
Thus, when the dimension adjustment of the separation distance between both bus ducts is performed by the change in the amount of deflection of the flexible conductor 5 and the change in the amount of overlap between the boxes, the box 43 and the box are finally When the bolts 46 are tightened into the screw holes provided in the box 44 at the portion of the long hole 45 with the body 44 via a washer 47 or the like, the mounting of the bus duct unit 40 for adjusting the dimensions between the opposing standard bus ducts Is completed.

より判り易く説明すると、接続するバスダクト間の離間距離を寸法調整は、バスダクト間の離間距離が狭いほど可撓性導体５がより撓み、箱体４３、４４間の重なり量が多くなり、逆に離間距離があまり狭くなければ可撓性導体５の撓み量はより少なくなり、箱体４３、４４間の重なり量も同様により少なくなって、離間距離の寸法調整が行われる。   To explain more easily, the distance between the bus ducts to be connected is adjusted. The smaller the distance between the bus ducts, the more the flexible conductor 5 bends and the amount of overlap between the box bodies 43 and 44 increases. If the separation distance is not so narrow, the amount of flexure of the flexible conductor 5 is reduced, and the amount of overlap between the box bodies 43 and 44 is similarly reduced, and the dimension adjustment of the separation distance is performed.

尚、前述した寸法調整用バスダクトユニット４０としては、図７に示すものの他に、例えば特許文献２に記載されているようなものもある。   As the above-described dimension adjusting bus duct unit 40, there is one described in Patent Document 2, for example, in addition to the one shown in FIG.

特開平１１−２９９０６４号公報Japanese Patent Laid-Open No. 11-299064 特開２００３−１５８８１２号公報JP 2003-158812 A

ところで前述した寸法調整用バスダクトユニット４０をバスダクトの水平曲り部に用いた場合には、前述した図６が示すように水平曲りバスダクト３０の他に２つの寸法調整用バスダクトユニット４０を必要とする。すなわち３つの部品を必要とすることになる。その結果、部品管理も大変であり、しかも接続作業箇所も多くなって接続作業に多くの時間が必要になる、という問題がある。   When the above-described dimension adjusting bus duct unit 40 is used in a horizontal bent portion of the bus duct, two dimension adjusting bus duct units 40 are required in addition to the horizontal bent bus duct 30 as shown in FIG. That is, three parts are required. As a result, there is a problem that parts management is difficult, and more connecting work points are required, so that more time is required for the connection work.

そこで本発明の目的は、バスダクトの水平曲り部を形成するに際し、部品点数を少なくでき、それ故、部品管理が容易で、しかも接続作業時間を短縮できるＬ字型寸法調整用バスダクトユニットを提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an L-shaped dimension adjusting bus duct unit that can reduce the number of parts when forming a horizontal bent portion of a bus duct, and therefore can easily manage parts and shorten the connection work time.

このようにしてなる請求項１記載のＬ字型寸法調整用バスダクトユニットによれば、その両端に、このＬ字型寸法調整用バスダクトユニットを構成するＬ字型の剛性筒体に対して出入り可能に装着されてなる伸縮調整バスダクト部材を有しているため、１つのＬ字型寸法調整用バスダクトユニットを用いるだけで、このＬ字型寸法調整用バスダクトユニットの両端に接続する、すなわち２方向に接続するバスダクトとの離間距離の寸法調整が可能なＬ字型寸法調整用バスダクトユニットを提供することができる。
そして使用する部品がこのＬ字型寸法調整用バスダクトユニットだけであるため、部品管理も容易で、しかも部品点数が少ないことから必要な接続箇所も少なくなり、接続作業時間の短縮も図ることができる。 According to the L-shaped dimension adjusting bus duct unit according to claim 1, the L-shaped rigid cylindrical body constituting the L-shaped dimension adjusting bus duct unit can enter and exit at both ends thereof. Since the expansion / contraction adjustment bus duct member is attached to the two ends, it is connected to both ends of the L-shaped dimension adjustment bus duct unit by using only one L-shaped dimension adjustment bus duct unit, that is, in two directions. It is possible to provide an L-shaped dimensional adjustment bus duct unit capable of adjusting the dimension of the separation distance from the bus duct to be connected.
Since only the L-shaped dimension adjusting bus duct unit is used, parts management is easy, and since the number of parts is small, the number of necessary connection points is reduced and the connection work time can be shortened. .

また請求項２記載のＬ字型寸法調整用バスダクトユニットは、請求項１記載のＬ字型寸法調整用バスダクトユニットにおいて、前記Ｌ字型の剛性筒体内における前記伸縮調整バスダクト部材は、前記Ｌ字型の剛性筒体端部に装着されている蓋体との間に間隔を有した状態で支持部材を有していて、前記蓋体と前記支持部材との間隔を調整することで前記伸縮調整バスダクト部材の前記Ｌ字型の剛性筒体に対する出入り量を調整できるようになっていることを特徴とするものである。   The L-shaped dimension adjusting bus duct unit according to claim 2 is the L-shaped dimension adjusting bus duct unit according to claim 1, wherein the expansion / contraction adjusting bus duct member in the L-shaped rigid cylinder is the L-shaped adjusting duct. The elastic member has a support member in a state where there is a gap between the lid attached to the rigid cylinder end of the mold, and the expansion and contraction adjustment is performed by adjusting the gap between the lid and the support member. The amount of the bus duct member that enters and exits the L-shaped rigid cylinder can be adjusted.

このようにしてなる請求項２記載のＬ字型寸法調整用バスダクトユニットによれば、前記Ｌ字型の剛性筒体内における前記伸縮調整バスダクト部材に、前記Ｌ字型の剛性筒体端部に装着されている蓋体との間に間隔を有した状態で支持部材を装着しただけの簡単な構成で、しかもこれら蓋体と支持部材との間隔を調整するだけで前記伸縮調整バスダクト部材の前記Ｌ字型の剛性筒体に対する出入り量を簡単に調整することができる。すなわち、接続するバスダクトとの離間距離が一定でなくとも、１つの部品でその接続距離を容易に調整することができる。   According to the L-shaped dimension adjusting bus duct unit according to claim 2, the expansion adjusting bus duct member in the L-shaped rigid cylinder is attached to the end of the L-shaped rigid cylinder.

The amount of entering and exiting the letter-shaped rigid cylinder can be easily adjusted. That is, even if the distance from the bus duct to be connected is not constant, the connection distance can be easily adjusted with one component.

さらに本発明の請求項３記載のＬ字型寸法調整用バスダクトユニットは、請求項２記載のＬ字型寸法調整用バスダクトユニットにおいて、前記Ｌ字型の剛性筒体の端部に装着された蓋体と前記伸縮調整バスダクト部材に設けられた支持部材とに跨って、これら蓋体と支持部材との間隔を調整する間隔調整ボルトが設けられていることを特徴としている。   Furthermore, the L-shaped dimension adjusting bus duct unit according to claim 3 of the present invention is the L-shaped dimension adjusting bus duct unit according to claim 2, wherein the lid is attached to an end of the L-shaped rigid cylinder. A space adjustment bolt for adjusting the space between the lid and the support member is provided across the body and the support member provided on the expansion / contraction adjustment bus duct member.

このようにしてなる請求項３記載のＬ字型寸法調整用バスダクトユニットによれば、前記Ｌ字型の剛性筒体の端部に装着された蓋体と、前記伸縮調整バスダクト部材に設けられた支持部材との間隔を、ボルトという汎用の部品で調整することが可能になる。
それ故、スパナ等の汎用の工具が使用でき、しかも容易にボルトの締め込み量を調整できるため、接続するバスダクトとの離間距離の調整作業、すなわち寸法調整作業を極めて容易に行うことができる。 According to the L-shaped dimension adjusting bus duct unit according to claim 3, the lid body mounted on the end of the L-shaped rigid cylinder and the expansion / contraction adjusting bus duct member are provided. It becomes possible to adjust the space | interval with a supporting member with general-purpose components called a volt | bolt.

以上のように本発明によれば、バスダクトの水平曲り部を形成するに際し、部品点数を少なくでき、それ故、部品管理が容易で、しかも接続作業時間を短縮できるＬ字型寸法調整用バスダクトユニットを提供することができる。   As described above, according to the present invention, when forming a horizontal bent portion of a bus duct, an L-shaped dimension adjusting bus duct unit that can reduce the number of components, and therefore can easily manage components and reduce the connection work time. Can be provided.

以下に本発明のＬ字型寸法調整用バスダクトユニットを図１〜図４を用いて詳細に説明する。
図１は本発明のＬ字型寸法調整用バスダクトユニットの一実施例を示すもので、Ｌ字型寸法調整用バスダクトユニットのＬ字型の剛性筒体３の上部を水平に切断して内部を見た説明図である。 Hereinafter, the L-shaped dimension adjusting bus duct unit of the present invention will be described in detail with reference to FIGS.
FIG. 1 shows an embodiment of an L-shaped dimension adjusting bus duct unit according to the present invention. The upper part of an L-shaped rigid cylindrical body 3 of the L-shaped dimension adjusting bus duct unit is horizontally cut so that the inside is shown. FIG.

図１が示すように、本発明のＬ字型寸法調整用バスダクトユニットは、金属製でＬ字型の剛性筒体３と、このＬ字型の剛性筒体３の両端部に、このＬ字型の剛性筒体３に対して出入り可能に装着されてなる伸縮調整バスダクト部材７と、この伸縮調整バスダクト部材７をＬ字型の剛性筒体３内で電気的に接続する可撓性導体５とを備えている。
前記伸縮調整バスダクト部材７は、銅板あるいはアルミニウム板からなる導体２ａに絶縁被覆を施した絶縁被覆導体２を複数本積層し、これを金属製のハウジング６で覆ったもので、その両端部には絶縁被覆導体２を接続のために広げた拡開段部４がそれぞれ形成されている。尚、絶縁被覆導体２は、その拡開段部４の先端で絶縁被覆が必要長剥ぎ取られ導体２ａが露出されている。
また可撓性導体５は、アルミニウム製の薄板を複数枚積層したものである。もちろん薄い銅板を複数枚積層したものであってもよい。 As shown in FIG. 1, the L-shaped dimension adjusting bus duct unit of the present invention is made of a metal L-shaped rigid cylinder 3 and the L-shaped rigid cylinder 3 at both ends thereof. Expansion / contraction adjustment bus duct member 7 detachably attached to the rigid cylinder 3 of the mold, and a flexible conductor 5 that electrically connects the expansion / contraction adjustment bus duct member 7 within the L-shaped rigid cylinder 3. And.
The expansion / contraction adjustment bus duct member 7 is formed by laminating a plurality of insulation-coated conductors 2 in which a conductor 2a made of a copper plate or an aluminum plate is coated with an insulation coating, and covering them with a metal housing 6 at both ends thereof. Expanded stepped portions 4 are formed by spreading the insulating coated conductor 2 for connection. The insulating coating conductor 2 is stripped of the necessary length of the insulating coating at the tip of the expansion step 4 to expose the conductor 2a.
The flexible conductor 5 is a laminate of a plurality of aluminum thin plates. Of course, a plurality of thin copper plates may be laminated.

またＬ字型の剛性筒体３内における伸縮調整バスダクト部材７は、Ｌ字型の剛性筒体３の端部に装着されている蓋体３ａとの間に間隔を有した状態で支持部材８を有していて、蓋体３ａと支持部材８との間隔をこれら蓋体３ａと支持部材８とに跨って装着されている間隔調整ボルト９の締め込み量を調整することで調整できる。すなわち、蓋体３ａと支持部材８との間隔を調整することで、Ｌ字型の剛性筒体３に対する伸縮調整バスダクト部材７の出入り量、換言するとＬ字型の剛性筒体３の蓋体３ａからの伸縮調整バスダクト部材７の突出量を調整することができるようになっている。   The expansion / contraction adjustment bus duct member 7 in the L-shaped rigid cylindrical body 3 has a support member 8 in a state of being spaced from the lid 3 a attached to the end of the L-shaped rigid cylindrical body 3. The distance between the lid 3a and the support member 8 can be adjusted by adjusting the tightening amount of the distance adjusting bolt 9 that is mounted across the lid 3a and the support member 8. That is, by adjusting the distance between the lid 3 a and the support member 8, the amount of the expansion / contraction adjustment bus duct member 7 with respect to the L-shaped rigid cylinder 3, in other words, the lid 3 a of the L-shaped rigid cylinder 3. The amount of protrusion of the expansion / contraction adjustment bus duct member 7 can be adjusted.

ここで支持部材８の間隔調整ボルト９が貫通する部分には、ナット１０が溶接等により取り付けられていて、間隔調整ボルト９をこのナット１０に螺合させることで支持部材８をＬ字型の剛性筒体３の蓋体３ａに近づけたり、逆に蓋体３ａから離したりして、蓋体３ａと支持部材８との間隔を調整する。ここで符号９ａは間隔調整ボルト９に設けられているネジ部を示している。
ところで支持部材８は伸縮調整バスダクト部材７の金属製のハウジング６に溶接等でしっかりと固定されている。 Here, a nut 10 is attached to a portion of the support member 8 through which the interval adjusting bolt 9 penetrates by welding or the like, and the interval adjusting bolt 9 is screwed into the nut 10 so that the support member 8 is L-shaped. The distance between the lid body 3a and the support member 8 is adjusted by moving the rigid cylinder body 3 closer to the lid body 3a or conversely away from the lid body 3a. Here, reference numeral 9a denotes a screw portion provided on the distance adjusting bolt 9.
Incidentally, the support member 8 is firmly fixed to the metal housing 6 of the expansion / contraction adjustment bus duct member 7 by welding or the like.

伸縮調整バスダクト部材７のＬ字型の剛性筒体３内の端部においては、絶縁被覆導体２の導体２ａと可撓性導体５とが接続スリーブ１１により接続されている。   At the end of the expansion / contraction adjustment bus duct member 7 in the L-shaped rigid cylinder 3, the conductor 2 a of the insulating coated conductor 2 and the flexible conductor 5 are connected by a connection sleeve 11.

このようにしてなるＬ字型寸法調整用バスダクトユニットによりバスダクトの曲り部の両端で接続する別のバスダクトとの間の離間距離を寸法調整しながら接続する場合について、以下により具体的に説明する。
尚、可撓性導体５の長さを含めこのＬ字型寸法調整用バスダクトユニットそのものは、接続する標準のバスダクトとの離間距離が最大になると予想される場合でも対応できるように、その長さが設計されており、基本的にはこの最大離間距離よりも接続する相手のバスダクトとの距離が設計値より狭い場合に、その寸法を調整できるように考えられている。
それ故、以下には接続する相手バスダクトとの離間距離が設計値より狭い場合の寸法調整方法を、図１における水平方向の伸縮調整バスダクト部材７を拡大した図２を用いて説明することにする。 A case where the L-shaped dimension adjusting bus duct unit is connected while adjusting the distance between the other ducts connected at both ends of the bent portion of the bus duct will be described in detail below.
The L-shaped dimension adjusting bus duct unit itself including the length of the flexible conductor 5 is so long that the distance from the standard bus duct to be connected is expected to be maximized. Basically, it is considered that the dimension can be adjusted when the distance to the bus duct of the other party to be connected is smaller than the design value than the maximum separation distance.
Therefore, in the following, the dimension adjustment method when the distance from the connected bus duct to be connected is narrower than the design value will be described with reference to FIG. 2 in which the horizontal expansion / contraction adjustment bus duct member 7 in FIG. 1 is enlarged. .

予め接続する相手バスダクトとの離間距離が最大の場合に対応できるようにＬ字型の剛性筒体３の蓋体３ａからの伸縮調整バスダクト部材７の突出量をほぼ最大にしたＬ字型寸法調整用バスダクトユニットを用意しておく。
そして接続相手のバスダクトとの距離が設計値より狭い場合には、図２における伸縮調整バスダクト部材７を矢印Ａ方向に移動させる必要がある。この場合には、蓋体３ａから突出している間隔調整ボルト９の頭部をスパナ等の工具で反時計方向に回転し、伸縮調整バスダクト部材７のＬ字型の剛性筒体３内に位置する部分に装着されている支持部材８を矢印Ｂ方向に移動させる。支持部材８の矢印Ｂ方向への移動に伴って伸縮調整バスダクト部材７全体がＬ字型の剛性筒体３内に引き込まれ、その際可撓性導体５もＬ字型の剛性筒体３内で撓んで伸縮調整バスダクト部材７のＬ字型の剛性筒体３内への移動を可能にする。 L-shaped dimension adjustment in which the amount of protrusion of the expansion / contraction adjustment bus duct member 7 from the lid 3a of the L-shaped rigid cylindrical body 3 is substantially maximized so as to be able to cope with the case where the distance from the bus duct connected in advance is maximum. Prepare a bus duct unit.
If the distance to the bus duct of the connection partner is narrower than the design value, it is necessary to move the expansion / contraction adjustment bus duct member 7 in FIG. In this case, the head of the gap adjusting bolt 9 protruding from the lid 3a is rotated counterclockwise with a tool such as a spanner, and is positioned in the L-shaped rigid cylinder 3 of the expansion / contraction adjustment bus duct member 7. The support member 8 attached to the portion is moved in the direction of arrow B. As the support member 8 moves in the direction of the arrow B, the entire expansion / contraction adjustment bus duct member 7 is drawn into the L-shaped rigid cylindrical body 3, and the flexible conductor 5 is also inside the L-shaped rigid cylindrical body 3. To allow the expansion / contraction adjustment bus duct member 7 to move into the L-shaped rigid cylinder 3.

ところで前述した図７が示す従来の寸法調整用バスダクトユニット４０の場合には、水平曲りバスダクト３０と寸法調整用バスダクトユニット４０との接続作業に際して、可撓性導体５に可撓性があるとはいっても、実際にはこの可撓性導体５は前述したように銅板とかアルミニウム板といった金属板であるが故に、小さな力で簡単に撓むものではない。そのため離間距離の微調整が必要な場合には、調整作業が難しく、調整時間も長く掛かる、という問題があった。
しかしながら図１、図２が示す本発明のＬ字型寸法調整用バスダクトユニットを用いれば、伸縮調整バスダクト部材７と接続相手のバスダクトとの離間距離の寸法調整は、間隔調整ボルト９を汎用のスパナ等を用いて調整できるため作業が極めて容易である。しかも微妙な寸法調整を必要と考えるならば、間隔調整ボルト９のねじ部９ａのねじピッチをより小さいものにするだけで対応できる、という利点もある。
ところで離間距離の寸法調整の際に、伸縮調整バスダクト部材７の蓋体３ａからの突出量を大きくしたい場合には、間隔調整ボルト９を前述した場合とは逆方向に捩じって、伸縮調整バスダクト部材７のＬ字型の剛性筒体３内に位置する部分に装着されている支持部材８を蓋体３ａ側に移動させればよい。 Incidentally, in the case of the conventional dimension adjusting bus duct unit 40 shown in FIG. 7 described above, the flexible conductor 5 is said to be flexible when the horizontal bent bus duct 30 and the dimension adjusting bus duct unit 40 are connected. However, since the flexible conductor 5 is actually a metal plate such as a copper plate or an aluminum plate as described above, it is not easily bent with a small force. Therefore, when fine adjustment of the separation distance is necessary, there is a problem that adjustment work is difficult and adjustment time is long.
However, if the L-shaped dimension adjustment bus duct unit of the present invention shown in FIGS. 1 and 2 is used, the distance adjustment bolt 9 can be used as a general-purpose spanner to adjust the distance between the expansion / contraction adjustment bus duct member 7 and the bus duct to be connected. The operation can be made very easily because it can be adjusted using the In addition, if it is considered that fine dimensional adjustment is necessary, there is also an advantage that it is possible to cope with it by simply making the screw pitch of the screw portion 9a of the distance adjusting bolt 9 smaller.
By the way, when adjusting the separation distance, if it is desired to increase the amount of protrusion of the expansion / contraction adjustment bus duct member 7 from the lid 3a, the distance adjustment bolt 9 is twisted in the opposite direction to that described above to adjust the expansion / contraction. What is necessary is just to move the support member 8 with which the part located in the L-shaped rigid cylinder 3 of the bus duct member 7 is moved to the cover body 3a side.

図３は本発明のＬ字型寸法調整用バスダクトユニットの別の実施例を示すもので、可撓性導体５として銅やアルミニウム製の薄板を積層したものではなく、例えば銅線を編組状にしたものを用いている。
それ故、可撓性導体５と伸縮調整バスダクト部材７の絶縁被覆導体２の導体２ａとの接続は、前記図１、図２に示したような接続スリーブ１１ではなく、可撓性導体５の端末に接続した板状端子付き接続端子１２を用いている。すなわち可撓性導体５の端部に装着した板状端子付き接続端子１２の板状端子の中央に形成されているボルト穴と絶縁被覆導体２の板状導体２ａに設けられているボルト穴とにボルト１３を通し、これをナット１４で締め込んで導体２ａと板状端子付き接続端子１２の板状端子とを面接触させ、電気的に接続している。それ以外は図１、図２に示しものと基本的に同じであるため詳細な説明は省略する。 FIG. 3 shows another embodiment of the L-shaped dimension adjusting bus duct unit of the present invention. The flexible conductor 5 is not formed by laminating copper or aluminum thin plates. For example, a copper wire is braided. We use what we did.
Therefore, the connection between the flexible conductor 5 and the conductor 2a of the insulation coated conductor 2 of the expansion / contraction adjustment bus duct member 7 is not the connection sleeve 11 as shown in FIGS. A connection terminal 12 with a plate-like terminal connected to the terminal is used. That is, a bolt hole formed in the center of the plate-like terminal of the connection terminal 12 with a plate-like terminal attached to the end of the flexible conductor 5 and a bolt hole provided in the plate-like conductor 2a of the insulating coated conductor 2 Bolts 13 are passed through and tightened with nuts 14 so that the conductor 2a and the plate-like terminals of the connection terminals 12 with plate-like terminals are brought into surface contact and are electrically connected. The rest is basically the same as that shown in FIG. 1 and FIG.

図４は本発明のＬ字型寸法調整用バスダクトユニットのさらに別の実施例を示すもので、支持部材８を灰皿状にしてその機械的強度を上げてある。それ以外の部分は前述した図３に示す実施例と同じ故、ここでは詳細な説明を省略する。   FIG. 4 shows still another embodiment of the L-shaped dimension adjusting bus duct unit of the present invention, in which the support member 8 is made ashtray to increase its mechanical strength. Since other parts are the same as those of the embodiment shown in FIG. 3 described above, detailed description thereof is omitted here.

尚、前記各実施例では伸縮調整バスダクト部材７のＬ字型の剛性筒体３端部からの出入り量（突出量）を間隔調整ボルト９で調整しているが、間隔調整ボルト９以外の手段を用いて支持部材８とＬ字型の剛性筒体３の蓋体３ａとの間隔を調整するようにしてもよいことはいうまでもない。   In each of the above embodiments, the amount of protrusion / extraction from the end portion of the L-shaped rigid cylindrical body 3 of the expansion / contraction adjustment bus duct member 7 is adjusted by the interval adjustment bolt 9, but means other than the interval adjustment bolt 9 are used. It goes without saying that the distance between the support member 8 and the lid 3a of the L-shaped rigid cylindrical body 3 may be adjusted using the above.

以上述べたように本発明のＬ字型寸法調整用バスダクトユニットによれば、バスダクトの曲り部で、接続する相手バスダクトとの離間距離の寸法調整をＬ字型の剛性筒体の蓋体と伸縮調整バスダクト部材に装着してある支持部材との間隔を調整するだけで行えるため、調整作業を極めて容易に行うことができる。
しかも用意する部品は本発明のＬ字型寸法調整用バスダクトユニットを１つ用意するだけでよいため、部品管理も容易で、かつ部品が１つであることに伴ない接続箇所も減り、その分接続作業時間の短縮を図ることもできる。 As described above, according to the L-shaped dimension adjusting bus duct unit of the present invention, the distance of the bus duct bent portion can be adjusted at the bent portion of the bus duct by adjusting the distance between the L-shaped rigid cylinder and the lid. Since adjustment can be performed simply by adjusting the distance from the support member mounted on the adjustment bus duct member, adjustment work can be performed very easily.
In addition, since only one L-shaped dimension adjusting bus duct unit of the present invention is required, the parts can be easily managed and the number of connection points associated with the single part is reduced. Connection work time can also be shortened.

このように本発明によれば、バスダクトの水平曲り部を形成するに際し、部品点数を少なくでき、それ故、部品管理が容易で、しかも接続作業時間を短縮できるＬ字型寸法調整用バスダクトユニットを提供することができる。   Thus, according to the present invention, an L-shaped dimension adjusting bus duct unit that can reduce the number of parts when forming the horizontal bent portion of the bus duct, and therefore can easily manage parts and reduce the connection work time. Can be provided.
