Description

本発明はバスダクト及びバスダクトの接続部防水構造、特に、主に屋外にて使用するバスダクト及びバスダクトの接続部防水構造に関する。 The present invention relates to a bus duct and a waterproof structure for a connecting portion of the bus duct, and more particularly to a bus duct used mainly outdoors and a waterproof structure for the connecting portion of the bus duct.

従来より、２つのハウジング半体を接合させて形成される収納部に、密着積層された複数の絶縁被覆導体を収納し、所定の箇所に設置する密着絶縁型バスダクト（以下、単に「バスダクト」という）が知られている。そして、このようなバスダクトを内部に収納した導体端部同士を相互に電気的に接続する接続部で連結して所望の長さとするバスダクト幹線が形成されている。 Conventionally, a close-insulated bus duct (hereinafter simply referred to as a “bus duct”) in which a plurality of insulation-coated conductors that are closely stacked are stored in a storage portion formed by joining two housing halves and installed at a predetermined location. )It has been known. And the bus duct trunk line which connects the conductor edge part which accommodated such a bus duct in the connection part which electrically connects mutually is made into the desired length.

この種のバスダクト幹線を屋外に配設する場合、例えば、所定間隔毎に設けられたバスダクト支持手段の支持部上面にバスダクトを内部の絶縁被覆導体が上下に積層状態となるように横置きにして載置固定する構成がとられる。そして、この様な屋外における設置構成においては、バスダクト及びその接続部に関しては風雨に耐え得る防水構造を確保することが重要となる。 When this type of bus duct trunk line is installed outdoors, for example, the bus duct is placed horizontally on the upper surface of the support portion of the bus duct support means provided at predetermined intervals so that the inner insulated conductors are laminated in the vertical direction. The structure which mounts and fixes is taken. In such an outdoor installation configuration, it is important to secure a waterproof structure that can withstand wind and rain with respect to the bus duct and its connecting portion.

この防水構造として、バスダクト全体を、防水カバーで完全に囲う技術が知られているが、これでは部品点数も多く、装置全体が大型化してしまい、また、複数の被覆構造が生じることで放熱性に劣る構成となる。そこで、例えば、特許文献１では、比較的シンプルな構造の防水型バスダクトが開示されている。同文献第１図に示されているように、バスダクトのハウジング本体（１）が積層された絶縁導体を上方からコ字状の形状で覆い、ハウジング本体（１）の両側壁が脚部となり、その内側に底蓋（２）が嵌め込まれ、この底蓋（２）が締結手段により上記脚部の下端部よりも上方位置でハウジング本体（１）に固定され、ハウジング本体（１）との間に形成される収納空間に積層された絶縁導体が収納されている。 As this waterproof structure, a technology that completely encloses the entire bus duct with a waterproof cover is known, but this increases the number of parts, the overall size of the device, and the heat dissipation due to the formation of multiple covering structures. It becomes a structure inferior to. Thus, for example, Patent Document 1 discloses a waterproof bus duct having a relatively simple structure. As shown in FIG. 1 of the same document, the insulated body in which the housing body (1) of the bus duct is laminated is covered with a U-shape from above, and both side walls of the housing body (1) are legs. A bottom cover (2) is fitted inside, and the bottom cover (2) is fixed to the housing body (1) at a position higher than the lower end of the leg by fastening means. The insulated conductor laminated | stacked in the accommodation space formed in this is accommodated.

すなわち、積層絶縁導体は下方から底蓋（２）で支持され、上方からハウジング本体（１）でカバーされた構成となっている。また、締結手段は、ハウジング本体（１）を貫通することなく、長ナット部をハウジング本体（１）の内側面に溶接等で固定しているので、ハウジング本体（１）の上部面には水が侵入する隙間は生じていない。したがって、上記脚部側を下にして設置することで、防水の図られたバスダクトの設置が可能となっている。 That is, the laminated insulated conductor is supported by the bottom cover (2) from below and covered by the housing body (1) from above. Further, the fastening means fixes the long nut portion to the inner surface of the housing body (1) by welding or the like without penetrating the housing body (1). There are no gaps intruding. Therefore, by installing the leg portion side down, it is possible to install a waterproof bus duct.

しかしながら、上記特許文献１のバスダクトでは、底蓋がハウジング本体にぶら下がっている構造を有していることから、底蓋を支える締結手段（ボルト）に絶縁被覆導体の全荷重が掛かることとなる。したがって、この構造の安定性を図るために、ボルトの数を多くして長期的に荷重に耐える構成を確保しなければならない。したがって、長ナットの溶接箇所も増加せざるを得ず、バスダクトの製造作業が煩雑なものとなる。また、このようなバスダクトを連結して構成されるバスダクト幹線の接続部の防水構造についても放熱性を確保した防水構造の提案が必要となっている。 However, the bus duct disclosed in Patent Document 1 has a structure in which the bottom cover is suspended from the housing body, and therefore, the entire load of the insulation-coated conductor is applied to the fastening means (bolts) that support the bottom cover. Therefore, in order to achieve the stability of this structure, the number of bolts must be increased to ensure a structure that can withstand the load for a long time. Therefore, the number of welded portions of the long nut is inevitably increased, and the manufacturing work of the bus duct becomes complicated. In addition, it is necessary to propose a waterproof structure that ensures heat dissipation for the waterproof structure of the connecting portion of the bus duct trunk line constituted by connecting such bus ducts.

本発明は上記課題に鑑みてなされてものであり、その目的は、バスダクトの部品点数の増加を伴うことなく、かつ構造の安定性を確保しつつ構成することのできるバスダクト及びバスダクトの接続部防水構造を提供することにある。 The present invention has been made in view of the above problems, and its object is to provide a bus duct that can be constructed without increasing the number of parts of the bus duct and ensuring the stability of the structure, and the waterproofing of the connecting portion of the bus duct. To provide a structure.

上記目的を達成するため、請求項１に係るバスダクトは、
複数の締結手段によって接合固定される２つのハウジング半体内に複数の導体を収納してなるバスダクトにおいて、前記２つのハウジング半体のうちの一方のハウジング半体は、前記導体を下方から支持する支持平板部と、該支持平板部の長辺部からほぼ直角に下方伸長した支持脚部と、該支持脚部の先端が屈曲された設置屈曲部と、を有する下側ハウジング半体として構成され、前記２つのハウジング半体のうちの他方のハウジング半体は、前記導体の上面側を覆う上部平板部と、該上部平板部の長辺部からほぼ直角に下方伸長した側面カバー部と、該側面カバー部の先端が屈曲されて前記下側ハウジング半体の前記支持平板部の外表面に接合設置される接合屈曲部と、を有する上側ハウジング半体として構成され、前記下側ハウジング半体の支持脚部と、前記上側ハウジング半体の前記側面カバー部とは、設置状態においてその外側面が面一となるように形成され、前記下側ハウジング半体の前記支持平板部と前記上側ハウジング半体の前記上部平板部とを締結手段により締結することで、前記下側ハウジング半体と前記上側ハウジング半体とを固定し、前記支持平板部の前記締結手段によって押圧されている部分の少なくとも一部及び前記上部平板部の前記締結手段によって押圧されている部分の少なくとも一部が、前記バスダクトの平面視で前記導体に重なっていることを特徴とする。 In order to achieve the above object, a bus duct according to claim 1 is:
In a bus duct formed by housing a plurality of conductors in two housing halves joined and fixed by a plurality of fastening means, one of the two housing halves supports the conductor from below. It is configured as a lower housing half having a flat plate portion, a support leg portion extending downward at a substantially right angle from the long side portion of the support flat plate portion, and an installation bent portion in which the tip of the support leg portion is bent, The other housing half of the two housing halves includes an upper flat plate portion covering the upper surface side of the conductor, a side cover portion extending downward at a substantially right angle from a long side portion of the upper flat plate portion, and the side surface A lower end of the lower housing half, and a lower end of the lower housing half. The support leg portion and the side cover portion of the upper housing half are formed so that the outer surfaces thereof are flush with each other in the installed state, and the support flat plate portion and the upper housing of the lower housing half By fastening the upper flat plate portion of the half body by fastening means, the lower housing half body and the upper housing half body are fixed, and at least a portion of the support flat plate portion pressed by the fastening means A part and at least a part of the part pressed by the fastening means of the upper flat plate part overlap the conductor in a plan view of the bus duct.

上記構成によれば、導体は、下側ハウジング半体の支持平板部の上面に載った状態で収納部内に納められている。そして、導体の上面側は、上側ハウジング半体によって被覆され、この上側ハウジング半体の側面カバー部の先端部は、下側ハウジング半体の支持平板部上に接合設置される。すなわち、上側ハウジング半体は導体と共に、下側ハウジング半体の支持平板部上に載置された状態となる。締結手段に荷重が掛かるのではなく、下側ハウジング半体の支持脚部に荷重が掛かる構成となっている。 According to the said structure, the conductor is accommodated in the accommodating part in the state mounted on the upper surface of the support flat plate part of a lower housing half body. The upper surface side of the conductor is covered with the upper housing half, and the tip of the side cover portion of the upper housing half is joined and installed on the support flat plate portion of the lower housing half. That is, the upper housing half is placed on the support flat plate portion of the lower housing half together with the conductor. Instead of applying a load to the fastening means, the load is applied to the support legs of the lower housing half.

したがって、導体の重量を支えるための締結手段の設置の必要性はなく、構造の簡略化が図られる。また、例えば、導体を絶縁被覆して積層させてなる密着絶縁型バスダクトとし、上側ハウジング半体の側面カバー部の伸長長さを絶縁被覆導体の積層厚さとほぼ同サイズに調整すれば、後は載置状態で設置されるので、下側ハウジング半体の支持脚部の長さ等との調整は不要となるため好適である。また、上側ハウジング半体の荷重が側面カバー部を介して下側ハウジング半体の支持脚部のほぼ真上から掛かることとなる。したがって、下側ハウジング半体の支持脚部の耐荷重性を有効に活用することができ、下側ハウジング半体による上側ハウジング半体の支持構造の安定化が図られる。 Therefore, there is no need to install fastening means for supporting the weight of the conductor, and the structure can be simplified. In addition, for example, a close-insulated bus duct in which conductors are insulated and laminated, and if the extension length of the side cover portion of the upper housing half is adjusted to approximately the same size as the laminated thickness of the insulated conductor, Since it is installed in a mounted state, adjustment with the length of the supporting leg portion of the lower housing half is unnecessary, which is preferable. Further, the load of the upper housing half is applied from almost right above the support leg portion of the lower housing half through the side cover portion. Therefore, the load resistance of the support leg portion of the lower housing half can be effectively utilized, and the support structure of the upper housing half can be stabilized by the lower housing half.

以下、本発明の実施形態について図面に基づいて詳細に説明する。図１は本発明に係る密着絶縁型バスダクト（以下、「バスダクト」という）の構成を示す概略縦断面図であり、図２はその構成要素を分解して示している。図示のように、バスダクト１０は、２つのハウジング半体、下側ハウジング半体１２と上側ハウジング半体１４とを備え、両ハウジング半体１２，１４の組み合わせによって形成される収納部に密着積層した３層の絶縁被覆導体１６が収納されている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic longitudinal sectional view showing a configuration of a close-insulated bus duct (hereinafter referred to as “bus duct”) according to the present invention, and FIG. 2 is an exploded view of the components. As shown in the figure, the bus duct 10 includes two housing halves, a lower housing half 12 and an upper housing half 14, which are closely stacked on a storage portion formed by a combination of both housing halves 12 and 14. Three layers of the insulation-coated conductor 16 are accommodated.

両ハウジング半体１２、１４は、予め防錆処理としての塗装が施された板状の鋼板から成る基材所定を所定の形状、サイズに切断し、これを屈曲して形成している。まず、下側ハウジング半体１２は、上記鋼板の幅方向両端から所定長さの部分でそれぞれ下方にほぼ直角に屈曲され断面が略コ字形状とされている。図上下側の平板部は、絶縁被覆導体１６の載置される部分、すなわち絶縁被覆導体１６を下側から支持する支持平板部１２ａである。そして、上記屈曲された両側部が、バスダクト全体を支える支持脚部１２ｂである。支持脚部１２ｂの先端部は、更に、それぞれバスダクトの幅方向の内側方向にほぼ直角に屈曲された設置屈曲部１２ｃとなっている。なお、図２に示された様に支持平板部１２ａの両側部には、貫通孔１２ｄがそれぞれ形成されている。 Both the housing halves 12 and 14 are formed by cutting a predetermined base material made of a plate-shaped steel plate, which has been preliminarily coated as a rust preventive treatment, into a predetermined shape and size and bending it. First, the lower housing half body 12 is bent substantially perpendicularly downward at a predetermined length from both ends in the width direction of the steel sheet, and has a substantially U-shaped cross section. The flat plate portion on the upper and lower sides in the figure is a portion on which the insulating coated conductor 16 is placed, that is, a supporting flat plate portion 12a that supports the insulating coated conductor 16 from below. The bent side portions are support leg portions 12b that support the entire bus duct. Further, the distal end portion of the support leg portion 12b is an installation bent portion 12c that is bent substantially at right angles to the inner side in the width direction of the bus duct. As shown in FIG. 2, through holes 12d are formed in both side portions of the support flat plate portion 12a.

次に、上側ハウジング半体１４は、同じく鋼板の幅方向両端から所定長さの部分でそれぞれ下方にほぼ直角に屈曲され断面が略コ字形状とされている。図上上側の平板部は、絶縁被覆導体１６の上面部を覆う上部平板部１４ａである。そして、上記屈曲された両側部が、絶縁被覆導体１６の側面部を覆う側面カバー部１４ｂである。この側面カバー部１４ｂの先端部は、更に、それぞれバスダクト１０の幅方向の内側方向にほぼ直角に屈曲された接合屈曲部１４ｃとなっている。なお、側面カバー部１４ｂの図上縦方向の長さは、３層積層された絶縁被覆導体１６の厚さとほぼ同サイズとされている。また、図２に示された様に上部平板部１４ａの両側部には、貫通孔１４ｄがそれぞれ形成されている。 Next, the upper housing half 14 is bent substantially at a right angle downward at portions of a predetermined length from both ends in the width direction of the steel plate, and has a substantially U-shaped cross section. The upper flat plate portion in the drawing is an upper flat plate portion 14 a that covers the upper surface portion of the insulating coated conductor 16. The bent side portions are side surface cover portions 14 b that cover the side surface portions of the insulating coated conductor 16. The front end portion of the side cover portion 14b is a joint bent portion 14c that is bent substantially at right angles to the inner side of the bus duct 10 in the width direction. Note that the length of the side cover portion 14b in the vertical direction in the drawing is substantially the same size as the thickness of the three insulation-coated conductors 16 stacked. Further, as shown in FIG. 2, through holes 14d are formed in both side portions of the upper flat plate portion 14a.

図１から理解されるように、上側ハウジング半体１４は、下側ハウジング半体１２の支持平板部１２ａの上面に載置された絶縁被覆導体１６の上側から被せられ、上部平板部１４ａの内側面と支持平板部１２ａの上面との間に絶縁被覆導体１６を挟むように設置される。上述のように、側面カバー部１４ｂの縦方向長さが３層の絶縁被覆導体１６とほぼ同様の長さとされているので絶縁被覆導体１６は下側ハウジング半体１２と上側ハウジング半体１４によって形成された空間（収納部）内にしっかりと収められる。 As can be understood from FIG. 1, the upper housing half 14 is covered from the upper side of the insulating coated conductor 16 placed on the upper surface of the support flat plate portion 12a of the lower housing half 12, and the inner half of the upper flat plate portion 14a. It is installed so that the insulation coating conductor 16 is pinched | interposed between a side surface and the upper surface of the support flat plate part 12a. As described above, since the length of the side cover portion 14b in the vertical direction is substantially the same as that of the three-layer insulating covering conductor 16, the insulating covering conductor 16 is formed by the lower housing half 12 and the upper housing half 14. It is securely stored in the formed space (storage part).

本実施の形態では、図２に示したように、両ハウジング半体１２，１４を固定するための締結手段は、絶縁被覆導体１６の幅方向両側の位置で、支持平板部１２ａと上部平板部１４ａとを貫通するように設けられている。すなわち、結合手段は貫通孔１２ｄ、１４ｄに挿通されるボルト１８及びこれを受けるナット２０を有しており、上下側ハウジング半体１４、１２の平板部１４ａ、１２ａを貫通して緊締される。なお、上側ハウジング半体１４の上部平板部１４ａ上側に突出するボルト１８のヘッドの部分には、皿ワッシャー２２，その下部に防水シール材２４が設置される。また、支持平板部１２ａの貫通孔１２ｄの部分に配されるナット２０の部分にも皿ワッシャー２８、スプリングワッシャー３０が設けられている。なお、下側ハウジング半体１２と上側ハウジング半体１４との接合部分である接合屈曲部１４ｃと支持平板部１２ａの間にも防水パッキン２６が設置され、収納部への水の侵入を防止している。なお、上記皿ワッシャー２２の付加的な作用として、ワッシャーの傾斜により、雨水が上側ハウジング半体１４の貫通孔１４ｄの部分に滞留するのを防止することができ、ひいては、収納部内への水の侵入を効果的に防止できる。 In the present embodiment, as shown in FIG. 2, the fastening means for fixing both housing halves 12, 14 are the support flat plate portion 12 a and the upper flat plate portion at the positions on both sides in the width direction of the insulating coated conductor 16. 14a is provided. That is, the coupling means has a bolt 18 inserted into the through holes 12d and 14d and a nut 20 for receiving the bolt 18 and is tightened through the flat plate portions 14a and 12a of the upper and lower housing halves 14 and 12. A dish washer 22 is installed at the head portion of the bolt 18 protruding above the upper flat plate portion 14 a of the upper housing half 14, and a waterproof seal material 24 is installed below the dish washer 22. Further, a plate washer 28 and a spring washer 30 are also provided on the portion of the nut 20 disposed in the portion of the through hole 12d of the support flat plate portion 12a. A waterproof packing 26 is also installed between the joint bent portion 14c, which is a joint portion between the lower housing half 12 and the upper housing half 14, and the support flat plate portion 12a to prevent water from entering the storage portion. ing. As an additional function of the dish washer 22, it is possible to prevent rainwater from staying in the through hole 14d of the upper housing half 14 due to the inclination of the washer. Intrusion can be effectively prevented.

なお、防水シール材２４の材質としては、ブチルゴム、アクリルゴム、クロロプレンゴム等のゴムやフェルト材等、押し潰されることにより密封性能を発揮する部材で構成されるのが好適である。また、防水パッキン２６も上記ゴムやフェルト材等の他、樹脂等でも良く、更に両面が粘着性を有するものを用いるのが好適であり、これにより接合屈曲部１４ｃと支持平板部１２ａとの密着性が増し、防水性が更に向上することができる。また、短絡事故が発生したような場合には、導体同士が離間する方向に力が働くが、この場合、防水パッキン２６が上下のハウジング半体１４、１２を密着させる方向に作用しているので、ハウジングの強度が増し、短絡時の衝撃への耐力が増加する。なお、防水パッキン２６自体が粘着性を有する場合に限らず、防水パッキン２６の両側に粘着両面テープを貼着してもよく、また、防水パッキン２６の両面に接着剤等の粘着材を塗布しても良い。 In addition, as a material of the waterproof seal material 24, it is preferable that the waterproof seal material 24 is composed of a member that exhibits a sealing performance by being crushed, such as rubber such as butyl rubber, acrylic rubber, or chloroprene rubber, or a felt material. Further, the waterproof packing 26 may be a resin other than the rubber or felt material, and it is preferable to use a material having adhesiveness on both sides, whereby the bonding bent portion 14c and the support flat plate portion 12a are adhered to each other. Thus, the waterproof property can be further improved. Further, when a short circuit accident occurs, force acts in the direction in which the conductors are separated from each other. In this case, the waterproof packing 26 acts in the direction in which the upper and lower housing halves 14 and 12 are brought into close contact with each other. The strength of the housing is increased, and the resistance to shock at the time of a short circuit is increased. The waterproof packing 26 itself is not limited to having adhesiveness, and an adhesive double-sided tape may be attached to both sides of the waterproof packing 26, and an adhesive material such as an adhesive is applied to both surfaces of the waterproof packing 26. May be.

本実施の形態では、上述の様に下側ハウジング半体１２と上側ハウジング半体１４との間の収納部には雨水が浸入しない構成となっている。なお、仮にハウジング内に雨水が浸入してしまった場合でも下側ハウジング半体１２の貫通孔１２ｄから水抜きができるように、皿ワッシャー２８と下側ハウジング半体１２の支持平板部１２ａとの間に防水シール材を設けていないが、更に、必要に応じて防水シール材を適宜設けてもよい。 In the present embodiment, rainwater does not enter the storage portion between the lower housing half 12 and the upper housing half 14 as described above. It should be noted that even if rainwater has entered the housing, the dish washer 28 and the support flat plate portion 12a of the lower housing half 12 can be drained from the through hole 12d of the lower housing half 12. Although no waterproof sealing material is provided between them, a waterproof sealing material may be provided as needed.

図１は、上述の締結手段としてのぼると１８、ナット２０により下側ハウジング半体１２と上側ハウジング半体１４とを締結した状態が示されており、絶縁被覆導体１６が下側ハウジング半体１２の支持平板部１２ａに載った状態で両ハウジング半体１２，１４内に収納されていることが理解される。すなわち、絶縁被覆導体１６及び上側ハウジング半体１４の荷重負担は締結手段１８，２０には掛かっておらず、締結手段１８，２０は絶縁被覆導体１６を支持平板部１２ａと上部平板部１４ａとの間に挟持せしめると共に下側ハウジング半体１２と上側ハウジング半体１４との位置固定を行う機能を果たし得る強度と個数が確保されれば足りる。すなわち、絶縁被覆導体１６及び上側ハウジング半体１４の荷重は下側ハウジング半体１２の支持平板部１２ａに掛かっており、支持脚部１２ｂによって支えられている。なお、締結手段は、絶縁被覆導体１６の長さ方向に亘って所定間隔をおいて複数設けられている。 FIG. 1 shows a state in which the lower housing half 12 and the upper housing half 14 are fastened by the nut 18 when the above-mentioned fastening means 18 is reached, and the insulation-coated conductor 16 is connected to the lower housing half 12. It is understood that the two housing halves 12 and 14 are accommodated in a state of being placed on the support flat plate portion 12a. That is, the load load of the insulating covering conductor 16 and the upper housing half 14 is not applied to the fastening means 18 and 20, and the fastening means 18 and 20 attach the insulating covering conductor 16 between the support flat plate portion 12a and the upper flat plate portion 14a. It is sufficient if the strength and the number that can be sandwiched between the lower housing half body 12 and the upper housing half body 14 and can secure the position of the upper housing half body 14 are secured. In other words, the loads of the insulating coated conductor 16 and the upper housing half 14 are applied to the support flat plate portion 12a of the lower housing half 12 and are supported by the support legs 12b. Note that a plurality of fastening means are provided at predetermined intervals along the length direction of the insulation-coated conductor 16.

本実施の形態では、上側ハウジング半体１４と下側ハウジング半体１２とを重合させたとき、支持脚部１２ｂと側面カバー部１４ｂとが上下に真っ直ぐ重なるように、すなわち、支持脚部１２ｂと側面カバー部１４ｂの外側面が面一となる様に支持平板部１２ａと上部平板部１４ａは、ほぼ同一の幅寸法に設定されている。これにより、下側ハウジング半体１２の支持脚部１２ｂの構造強度を効果的に活用することができ下側ハウジング半体１２によう支持状態の安定化が図られる。また、作業者等がバスダクト１０上を歩行するような、上側ハウジング１４に荷重が掛かる場合でも、その荷重は側面がバー部１４ｂを介して下側ハウジング１２の支持脚部１２ｂにほぼ真上から掛かることになり、下側ハウジング半体１２の支持平板部１２ａの面部分に掛かる荷重が小さいので、強度が増し、耐荷重性が向上する。 In the present embodiment, when the upper housing half 14 and the lower housing half 12 are superposed, the support leg 12b and the side cover 14b are vertically overlapped, that is, the support leg 12b. The support flat plate portion 12a and the upper flat plate portion 14a are set to have substantially the same width dimension so that the outer surface of the side cover portion 14b is flush with the other. Thereby, the structural strength of the support leg 12b of the lower housing half 12 can be effectively utilized, and the support state can be stabilized like the lower housing half 12. Further, even when a load is applied to the upper housing 14 such that an operator or the like walks on the bus duct 10, the load is applied to the supporting leg portion 12 b of the lower housing 12 from right above the side surface via the bar portion 14 b. Since the load is applied and the load applied to the surface portion of the support flat plate portion 12a of the lower housing half 12 is small, the strength is increased and the load resistance is improved.

また、上側ハウジング半体１４の接合屈曲部１４ｃの屈曲長さは、貫通する締結手段としてのボルト１８の軸が干渉しない長さで且つ軸の近傍まで伸長する長さに設定されている。したがって、接合屈曲部１４ｃには、ボルトの貫通孔を開ける加工をする必要がない。また、皿ワッシャー２８の押圧部分が接合屈曲部１４ｃの端部に対向するので、より効果的に水平部の端部の変形を防止することができる。また、上側ハウジング半体１４の両側をコ字形状としたので、締結手段１８，２０の締め付けに対しても上側ハウジング半体１４が変形してしまうことはなく、上部平板部１４ａ、側面カバー部１４ｂ、支持平板部１２ａ及び導体端部とで囲まれる空間Ｒに、別途補強部材を設ける必要がない。 Further, the bending length of the joint bending portion 14c of the upper housing half 14 is set to a length that does not interfere with the shaft of the bolt 18 serving as a fastening means that penetrates and extends to the vicinity of the shaft. Therefore, it is not necessary to perform the process of opening the through hole of the bolt in the joint bending portion 14c. Moreover, since the pressing part of the dish washer 28 opposes the edge part of the joining bending part 14c, a deformation | transformation of the edge part of a horizontal part can be prevented more effectively. Further, since both sides of the upper housing half 14 are U-shaped, the upper housing half 14 is not deformed even when the fastening means 18 and 20 are tightened, and the upper flat plate portion 14a and the side cover portion are not deformed. There is no need to separately provide a reinforcing member in the space R surrounded by 14b, the support flat plate portion 12a, and the conductor end.

また、上側ハウジング半体１４は、下側ハウジング半体１２上に載置されているので、上側ハウジング半体１４を締結手段１８，２０意外に別途ねじ等で下側ハウジング半体１２に固定する必要がない。したがって、施工が容易になると共に、部品点数を削減することができる。 Further, since the upper housing half 14 is mounted on the lower housing half 12, the upper housing half 14 is fixed to the lower housing half 12 with screws or the like other than the fastening means 18 and 20. There is no need. Therefore, construction becomes easy and the number of parts can be reduced.

図３は、上述した構成を有する本発明に係るバスダクト１ピースの全体構成を示しており、同図（Ａ）は上側ハウジング半体１４側から視た図、同図（Ｂ）は側方から視た図が示されている。図示のように、内部に収納された絶縁被覆導体１６の絶縁被覆部の除去された両端が露出しており、その他の部分は上述したハウジング半体１２、１４によってカバーされている。 FIG. 3 shows an overall configuration of a bus duct 1 piece according to the present invention having the above-described configuration. FIG. 3 (A) is a view seen from the upper housing half 14 side, and FIG. 3 (B) is a side view. A view is shown. As shown in the drawing, both ends of the insulation coating portion of the insulation coating conductor 16 housed therein are exposed, and the other portions are covered by the housing halves 12 and 14 described above.

上側及び下側のハウジング半体１４、１２を固定する締結手段（ボルト１８）はハウジングの両側縁部の近傍位置に絶縁被覆導体１６を挟持するのに必要な個数だけ（図３ではそれぞれ４個ずつ）設けられている。下側ハウジング半体１２及び上側ハウジング半体１４の長手方向両端部には厚さ方向の幅を拡大させた端部板部３４が設けられており、本実施の形態では上部平板部１４ａと支持平板部１２ａとを延出かつ屈曲させて構成している。絶縁被覆導体１６はこの端部板部３４の部分で３層の導体が密着状態から所定間隔ずつ離隔された状態となり絶縁被覆を除去した導体端部１６ａの部分で他の絶縁被覆導体１６（他のバスダクトに収納されその端部から露出している導体）と電気的に接続されるものである。 The number of fastening means (bolts 18) for fixing the upper and lower housing halves 14 and 12 is the same as the number necessary for sandwiching the insulated conductors 16 in the vicinity of both side edges of the housing (four in FIG. 3 each). Each). End plate portions 34 having an enlarged width in the thickness direction are provided at both longitudinal ends of the lower housing half body 12 and the upper housing half body 14. In the present embodiment, the upper plate portion 14 a and the support plate are supported. The flat plate portion 12a is extended and bent. The insulated conductor 16 is in a state where the three layers of conductors are separated from the contact state by a predetermined interval at the end plate portion 34, and the other insulated conductor 16 (others) at the conductor end portion 16a from which the insulation coating is removed. The conductor is housed in the bus duct and exposed from the end of the bus duct).

図４は、上述したバスダクト１０がバスダクト支持手段であるバスダクト支持架台４０の上部に形成された上面を水平面とした支持板４０ａに設置された状態が示されている。図示のようにバスダクト１０は、下側ハウジング半体１２の設置屈曲部１２ｃを支持板４０ａの上面に当接させて載置された状態とされている。そして、支持平板部１２ａの上面に上側ハウジング半体１４が同じく上部平板部１４ａが当接された状態で載置されている。すなわち、接合屈曲部１４ｃの下面が接触する支持平板部１２ａの上面がハウジング半体相互の接合部となっている（尚、締結手段や防水用のパッキン等については図示を省略している。）
そして、支持平板部１２ａと上部平板部１４ａの間に形成された空間に３層の絶縁被覆導体１６が収納されている。このように、絶縁被覆導体１６の全重量と上側ハウジング半体１４の全重量は支持平板部１２ａによって受けられ、支持脚部１２ｂによって支持されている。従って、下側ハウジング半体１２と上側ハウジング半体１４とを固定するための締結手段１８，２０（図１参照乞う）は絶縁被覆導体１６の重量を支えるために設けられるものではなく、上述のように絶縁被覆導体１６を挟持するため及び下側ハウジング半体１２と上側ハウジング半体１４の位置決め固定を行うためのみに機能するものである。 FIG. 4 shows a state in which the above-described bus duct 10 is installed on a support plate 40a having an upper surface formed in the upper part of a bus duct support frame 40 as a bus duct support means and having a horizontal surface. As shown in the figure, the bus duct 10 is placed in a state where the installation bent portion 12c of the lower housing half 12 is brought into contact with the upper surface of the support plate 40a. Then, the upper housing half body 14 is similarly placed on the upper surface of the support flat plate portion 12a with the upper flat plate portion 14a being in contact therewith. That is, the upper surface of the support flat plate portion 12a with which the lower surface of the joint bending portion 14c comes into contact is a joint portion between the housing halves (note that the fastening means, waterproof packing, etc. are not shown).
And the three-layer insulation coating conductor 16 is accommodated in the space formed between the support flat plate part 12a and the upper flat plate part 14a. In this way, the total weight of the insulating coated conductor 16 and the total weight of the upper housing half 14 are received by the support flat plate portion 12a and supported by the support leg portion 12b. Accordingly, the fastening means 18 and 20 (see FIG. 1) for fixing the lower housing half 12 and the upper housing half 14 are not provided to support the weight of the insulation-coated conductor 16, but are described above. Thus, it functions only for sandwiching the insulation coated conductor 16 and for positioning and fixing the lower housing half 12 and the upper housing half 14.

また、このバスダクト１０の支持板４０ａへの固定は図示したようにバスダクト１０の外側を上方から押さえる所定幅の固定金具４２によって行われる。固定金具４２は所定間隔毎に配置され、屈曲されて支持板４０ａ上に当接される取付け屈曲部４２ａの部分で、締結部４３によって固定され、バスダクト１０の支持板４０ａへの固定取り付けがなされている。 The bus duct 10 is fixed to the support plate 40a by a fixing bracket 42 having a predetermined width that holds the outside of the bus duct 10 from above as shown in the figure. The fixing brackets 42 are arranged at predetermined intervals, and are fixed by fastening portions 43 at the bent portions 42a that are bent and abutted on the support plate 40a, and the bus duct 10 is fixedly attached to the support plate 40a. ing.

図５は、上述した実施の形態に係るバスダクト１０が連結されバスダクト幹線がバスダクト支持架台４０上に設置された状態の一部抜き出した図であり、厚さ方向から図示されている。図示のように２つのバスダクト１０−１及び１０−２が接続部５０で絶縁被覆導体１６の導体端部１６ａ同士を電気的に接続すると共に連結されている。なお、接続部５０は接続ユニットを用いて構成されており、本実施の形態では接続方式として導体端部同士を突き合わせて当て板を用いて接続する、いわゆる突合せ方式を採用した例が示されているが、この接続構造は公知の技術であり、その詳述は省略する。 FIG. 5 is a partially extracted view of the state in which the bus duct 10 according to the above-described embodiment is connected and the bus duct trunk line is installed on the bus duct support base 40, and is illustrated from the thickness direction. As shown in the drawing, two bus ducts 10-1 and 10-2 are connected to each other while electrically connecting the conductor end portions 16 a of the insulating coated conductor 16 at the connection portion 50. In addition, the connection part 50 is comprised using the connection unit, and in this Embodiment, the example which employ | adopted what is called the butt | matching system which abuts conductor end parts as a connection method and connects using a contact plate is shown. However, this connection structure is a well-known technique and will not be described in detail.

本実施の形態において重要なことは、接続部５０に施されている防水構造であり、図６（Ａ）及び（Ｂ）にその構成要素が分解して示されている。図示のように、バスダクトの設置状態における最上部には上蓋５２が接続部５０全体を覆うように上方から被せ設置され、上側ハウジング半体１４上にその下端部が当接する状態で設置される。上蓋５０はその全周囲に下方にほぼ直角に屈曲させた側部５２ａを有し、その側部５２ａの先端部は更にほぼ直角に内側に屈曲され、雨水などの浸入を確実に防止している。 What is important in the present embodiment is a waterproof structure applied to the connecting portion 50, and its constituent elements are shown in exploded form in FIGS. 6 (A) and 6 (B). As shown in the figure, an upper lid 52 is placed on the uppermost portion of the bus duct in an installed state so as to cover the entire connecting portion 50, and is installed with its lower end abutting on the upper housing half 14. The upper lid 50 has a side portion 52a bent downward at substantially right angles around the entire periphery thereof, and the tip end portion of the side portion 52a is further bent inward at substantially right angles to reliably prevent intrusion of rainwater and the like. .

次に、上蓋５２の下部には側板５４が接続部５０を幅方向両側から挟むように設けられる（同図（Ｂ）参照乞う）。また、側板５４の図上左右両端部はバスダクト１０の下側ハウジング半体１２及び上側ハウジング半体１４の支持脚部１２ｂ、側面カバー部１４ｂの外側面に当接されて設置されており、接続部５０における突出部のない側面部を構成している。すなわち、飛び出し部のない小型の側部が形成されている。また、同図（Ａ）に示したように側板５４の内側面には接続部５０の端部板部３４の縁部形状に沿う範囲に防水パッキン５６が設けられている。この防水パッキン５６により接続部５０内への側板５４側からの浸水を確実に防止している。なお、側板５４は図上下端部に内側にほぼ直角に屈曲された屈曲部５４ａを有し、断面形状Ｌ字型の形状となっている。 Next, a side plate 54 is provided at the lower portion of the upper lid 52 so as to sandwich the connecting portion 50 from both sides in the width direction (see FIG. 5B). Further, both left and right ends of the side plate 54 in the drawing are installed in contact with the outer side surfaces of the lower housing half 12 and the upper housing half 14 of the bus duct 10 and the support leg 12b and the side cover 14b. The side part which does not have the protrusion part in the part 50 is comprised. That is, a small side portion without a protruding portion is formed. Further, as shown in FIG. 5A, a waterproof packing 56 is provided on the inner surface of the side plate 54 in a range along the edge shape of the end plate portion 34 of the connection portion 50. This waterproof packing 56 reliably prevents water from entering the connecting portion 50 from the side plate 54 side. In addition, the side plate 54 has a bent portion 54a bent at a substantially right angle on the inner side at the lower end in the figure, and has a L-shaped cross section.

次に、側板５４の下部には接続部５０の下面側をカバーする下蓋５８が設けられる。下蓋５８は同図（Ａ）に示されたように略コ字状の形状を有し、同図（Ａ）において左右両端にほぼ直角に上方に屈曲された側壁部５８ａを有している。この下蓋５８は側板５４の下端部に形成された屈曲部５４ａを下側から覆うように設置され、接続部５０の下面側をカバーしている。 Next, a lower lid 58 that covers the lower surface side of the connecting portion 50 is provided below the side plate 54. The lower lid 58 has a substantially U-shape as shown in FIG. 6A, and has a side wall portion 58a bent upward at substantially right angles at both left and right ends in FIG. . The lower lid 58 is installed so as to cover the bent portion 54 a formed at the lower end portion of the side plate 54 from below, and covers the lower surface side of the connecting portion 50.

図５からも理解されるように、上蓋５２が上述した接続部５０の防水をカバーするための他の部材側板５４、下蓋５８を含む全領域を上方からカバーしており、雨水等の進入を有効に防いでいる。また、接続部５０の側方も側板５４及びこの側板５４に設けられた防水パッキン５６によって密水性が保持されている。 As can be understood from FIG. 5, the upper lid 52 covers the entire region including the other member side plate 54 and the lower lid 58 for covering the waterproofing of the connecting portion 50 described above from the upper side. Is effectively prevented. Further, the side of the connecting portion 50 is also kept watertight by a side plate 54 and a waterproof packing 56 provided on the side plate 54.

更に、下蓋５８の上方に屈曲された屈曲部５８ａは、図５に示されているように、その設置状態においてバスダクト１０の最も接続部５０寄り位置にある締結手段（ボルト１８等）の設置位置よりも内側、すなわち接続部５０寄り位置で立ち上がるように構成されている。したがって、仮にバスダクト１０の収納部内に浸水が生じその水が締結手段の設置個所である貫通孔１２ｄ（図２参照乞う）から漏れ出した場合もその水が接続部５０内に進入することを確実に防止することができる構成となっている。 Further, as shown in FIG. 5, the bent portion 58a bent above the lower lid 58 is provided with a fastening means (bolt 18 or the like) located closest to the connecting portion 50 of the bus duct 10 in the installed state. It is configured to stand up from the position, that is, at a position closer to the connecting portion 50. Therefore, even if water is generated in the housing portion of the bus duct 10 and the water leaks out from the through hole 12d (see FIG. 2) where the fastening means is installed, it is ensured that the water enters the connecting portion 50. The configuration can be prevented.

また、上述した接続部防水構造の構成要素、上蓋５２、側板５４、下蓋５８は、それぞれ設置状態において上蓋５２が側板５４の上端部を上方からカバーし、下蓋５８が側板５４の下端部の屈曲部５４ａを下方からカバーすると共に、両側の側板５４間の下側開放部を塞いでいる。これにより、接続部５０への雨水等の侵入をシンプルな外方への凹凸の少ない形状により的確に達成している。 In addition, the components of the connection portion waterproof structure, the upper lid 52, the side plate 54, and the lower lid 58 described above, in the installed state, the upper lid 52 covers the upper end portion of the side plate 54 from above, and the lower lid 58 is the lower end portion of the side plate 54. The bent portion 54a is covered from below, and the lower open portion between the side plates 54 on both sides is closed. Thereby, the penetration | invasion of the rainwater etc. to the connection part 50 is exactly achieved with the simple shape with few unevenness | corrugations to the outward.

次に、図７及び図８は、上述したバスダクト幹線の曲がり角部分の防水構造を示している。図７は水平に直角に曲がった構成、図８は垂直に下方に屈曲した構成が示されている。なお、図において、上述した実施の形態と同様の要素には同一の符号を付し、その説明を省略する。両図に示されたように、曲がり角の前後２箇所に接続ユニット７０−１、７０−２及び８０−１、８０−２が設置されており、これら２つの接続ユニットの間に水平に直角に及び垂直に形成された絶縁被覆導体７２及び８２を接続している。上記図５及び図６に示した接続部５０の防水構造と異なる点は、直角の曲がり形状に対応させて、それぞれの構成要素を直角に曲げたことである。 Next, FIG.7 and FIG.8 has shown the waterproof structure of the corner part of the bus duct trunk line mentioned above. FIG. 7 shows a configuration bent horizontally at a right angle, and FIG. 8 shows a configuration bent vertically downward. In the figure, elements similar to those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. As shown in both figures, connection units 70-1, 70-2 and 80-1, 80-2 are installed at two places before and after the corner, and horizontally between these two connection units. Insulated coated conductors 72 and 82 formed vertically are connected. The difference from the waterproof structure of the connecting portion 50 shown in FIGS. 5 and 6 is that each component is bent at a right angle so as to correspond to a right-angled bent shape.

すなわち、図７の水平曲がり構成では、上蓋７４を水平に直角に曲がった形状とし、側板７６を直角の曲がり部の外側の側板７６−１と内側の側板７６−２とをそれぞれ曲がり部の側面形状に沿うように直角に曲がった形状とし、更に、下蓋７８も上蓋７４と同様に水平に直角に曲げた形状としている。 That is, in the horizontal bending configuration of FIG. 7, the upper lid 74 is horizontally bent at a right angle, and the side plate 76 is connected to the outer side plate 76-1 and the inner side plate 76-2 of the right bent portion, respectively. The shape is bent at a right angle so as to follow the shape, and the lower lid 78 is also bent at a right angle in the same manner as the upper lid 74.

その他の各要素の構成は、上記図５及び図６に示した基本構成と同様であり、最上部の上蓋７４は接続部５０全体を覆うように上方から被せ設置され、上側ハウジング半体１４上にその下端部が当接する状態で設置され、その全周囲に下方にほぼ直角に屈曲させた側部７４ａを有し、その側部７４ａの先端部は更にほぼ直角に内側に屈曲され、雨水などの浸入を確実に防止している。 The configuration of each other element is the same as the basic configuration shown in FIGS. 5 and 6 above, and the uppermost upper cover 74 is installed from above so as to cover the entire connection portion 50, and the upper housing half 14 is And has a side portion 74a bent at a substantially right angle downward at the entire periphery, and the tip end portion of the side portion 74a is bent at a substantially right angle inside, such as rainwater. Is surely prevented.

また、側板７６は、上蓋７４の下部で接続部７０を幅方向両側から挟むように設けられ、直角に曲がった接続部７０のバスダクト外側面から外方への突出部のない構成としている。なお、側板７６の下端部には同じく下端部に内側にほぼ直角に屈曲された屈曲部７６−１ａ、７６−２ａが設けられている。 Further, the side plate 76 is provided so as to sandwich the connecting portion 70 from both sides in the width direction at the lower portion of the upper lid 74, and has a configuration without a protruding portion outward from the outer surface of the bus duct bent at a right angle. In addition, the lower end portion of the side plate 76 is similarly provided with bent portions 76-1a and 76-2a that are bent at a substantially right angle inside the lower end portion.

最下部には、上蓋７４と同じく水平に直角に曲がった下蓋７８が、側板７６の屈曲部７６−１ａ、７６−２ａを下側から被覆し、接続部の下面側の開放部をカバーする様に設置される。下蓋７８の両端辺には設置状態で上方に立ち上がる屈曲部７８ａが設けられ、両端辺側からの雨水の浸入を防止している。なお、この屈曲部７８ａがその設置状態において、バスダクト１０の最も接続部よりの締結部（ボルト１８等）の位置よりも内側、すなわち接続部寄り位置に位置することも上記図５及び図６の構成と同様である。これにより、仮にバスダクトのハウジング内に浸入した雨水が締結手段の貫通する貫通部から排出されたとしても、再度防水構造部内に浸入することはない。 At the bottom, a lower lid 78 bent horizontally at a right angle like the upper lid 74 covers the bent portions 76-1a and 76-2a of the side plate 76 from below, and covers the open portion on the lower surface side of the connecting portion. Installed. Bending portions 78a that rise upward in the installed state are provided at both ends of the lower lid 78 to prevent intrusion of rainwater from both ends. In the installed state, the bent portion 78a may be located inside the position of the fastening portion (bolt 18 or the like) closest to the connecting portion of the bus duct 10, that is, closer to the connecting portion as shown in FIGS. The configuration is the same. As a result, even if rainwater that has entered the housing of the bus duct is discharged from the through portion through which the fastening means passes, it does not enter the waterproof structure portion again.

次に、図８の垂直に曲がった構成では、上蓋８４は上面が直方形の平面形状を有し、同じくその全周囲に下方にほぼ直角に屈曲させた側部８４ａを有している。側板８６は曲がり部分の側面をカバーする直角に曲がった対向配置される１対（２枚）の曲がり側板８６−１と、曲がり部分の外側に設置される１枚の外側板８６−２と内側に設置される１枚の内側板８６−３とを有している。そして、各側板８６−１、８６−２、８６−３には、その側辺にそれぞれ屈曲部８６−１ａ、８６−１ｂ、８６−２ａ、８６−３ａが設けられ、側部からの雨水の浸入を防止できる構成となっている。また、外側板８６−２と内側板８６−３の設置状態における下端辺には、この曲がり部の防水構造への下方からの雨水などの侵入を防止するために底部屈曲部８６−２ｂ、８６−３ｂがそれぞれ設けられ、上記側辺に設けられる屈曲部８６−２ａ、８６−３ａよりも長い屈曲長さとされている。 Next, in the vertically bent configuration of FIG. 8, the upper lid 84 has a rectangular planar shape on the upper surface, and also has a side portion 84 a bent substantially at a right angle downward on the entire periphery thereof. The side plate 86 is a pair of (two) bent side plates 86-1 that are arranged at right angles so as to cover the side surfaces of the bent portion, and one outer plate 86-2 that is installed outside the bent portion. And one inner plate 86-3. Each side plate 86-1, 86-2, 86-3 is provided with bent portions 86-1a, 86-1b, 86-2a, 86-3a on the sides thereof, and rainwater from the side portions is provided. It is configured to prevent intrusion. Further, bottom bent portions 86-2b and 86 are provided at the lower end sides of the outer plate 86-2 and the inner plate 86-3 in the installed state in order to prevent rainwater or the like from entering the waterproof structure of the bent portion from below. -3b is provided, and the bending length is longer than the bending portions 86-2a and 86-3a provided on the side.

下蓋８８は、曲がり部分に至る直前の水平部分の接続部ユニット８０−１の下面側の開放部分をカバーするものであり、水平に伸長する側の端辺及び垂下する側の端辺にそれぞれ設置状態で上方に立ち上がる屈曲部８８ａ及び８８ｂが形成されている。 The lower lid 88 covers the open part on the lower surface side of the connecting part unit 80-1 in the horizontal part immediately before reaching the bent part, and is respectively provided on the side edge extending horizontally and the side edge hanging down. Bending portions 88a and 88b rising upward in the installed state are formed.

各部材の設置は、曲がり部に存する接続部ユニット８０−１，８０−２の上部領域を覆うように最上部に上蓋８４が被せ設置され、その側部８４ａの上側ハウジング半体１４上に当接する状態で設置される先端部は更にほぼ直角に内側に屈曲され、雨水などの浸入を確実に防止している。 Each member is installed by placing an upper lid 84 on the uppermost portion so as to cover the upper region of the connection unit 80-1 and 80-2 existing at the bent portion, and contacting the upper housing half 14 of the side portion 84a. The tip that is installed in contact with each other is further bent inward at a substantially right angle to reliably prevent intrusion of rainwater and the like.

また、各側板８６−１、８６−２、８６−３は、上端部が上蓋８４内に収まる様に上蓋８４の下部で曲がり部を四方から挟むように設けられ、直角に曲がった接続部８０のバスダクト外側面から外方への突出部のない構成としている。 Further, each of the side plates 86-1, 86-2, 86-3 is provided so as to sandwich the bent portion from the four sides at the lower portion of the upper lid 84 so that the upper end portion is accommodated in the upper lid 84, and the connecting portion 80 bent at a right angle. The bus duct has an external protrusion from the outer surface of the bus duct.

曲がり部の垂下直前のバスダクト水平部の底面側には、図９に示された構成の下蓋８８が設置される。一方の屈曲部８８ａは、上記の実施の形態と同様に締結手段（ボルト１８など）の位置よりも接続部８０寄り位置に配置される構成となっており、これにより、バスダクト１０のハウジング内に雨水が侵入し雨水が締結手段の貫通する貫通部から排出された場合でも、再度防水構造部内に浸入することが防止される。また、他方の屈曲部８８ｂは内側板８６−３の設置状態における上端に高さを合わせて当接設置されており、水平側から垂下側への雨水の浸入を確実に防止している。 A lower lid 88 having the structure shown in FIG. 9 is installed on the bottom surface side of the horizontal portion of the bus duct immediately before the bent portion is suspended. One bent portion 88a is arranged at a position closer to the connecting portion 80 than the position of the fastening means (bolt 18 or the like) as in the above-described embodiment. Even when rainwater enters and the rainwater is discharged from the penetrating portion through which the fastening means passes, it is prevented from entering the waterproof structure portion again. Further, the other bent portion 88b is placed in contact with the upper end of the installed state of the inner plate 86-3 so as to have a height so as to reliably prevent rainwater from entering from the horizontal side to the drooping side.

更に、図示のように、垂下側の屈曲部８８ｂの折り曲げ部分の両端部には、雨水を排出できるように、切り欠き８８ｃが設けてあり、仮に、雨水の浸入が生じた場合でもその水を流出させることができる。特に、両端に切り欠き８８ｃを設けたので、いずれの方に勾配があったとしても、水が溜まることなく排水が可能となっている。 Furthermore, as shown in the figure, notches 88c are provided at both ends of the bent portion of the bent portion 88b on the drooping side so that rainwater can be discharged. Can be drained. In particular, since the notches 88c are provided at both ends, water can be drained without accumulating even if there is a gradient in either direction.

次に、図１０は、下側ハウジング半体１２と上側ハウジング半体１４との固定構造の他の構成例を示している。同図（Ａ）は、上側ハウジング半体１４の上部平板部１４ａにおける締結手段であるボルト１８のヘッド部分の受け構造に関して、図１に示した構成と異なり、上部平板部１４ａの貫通部の部分に膨出部１０２を設け、その膨出部１０２とボルトヘッド１８ａとの間に防水シール材１０４を介在させている。このようにボルト１８が貫通する部分を膨出させることで、雨水を上部平板部１４ａの他の部分に流すことができ、貫通部近傍に溜まることを防止することができる。なお、下側ハウジング半体１２の貫通部の部分についても同様の膨出部１０６を設けた構成とすることが好適である。これによって、仮に上側ハウジング半体１４の貫通部を通じて雨水がハウジング内に浸入しても、この膨出部１０６に雨水が案内され、貫通部を通じて外に排出することができる。 Next, FIG. 10 shows another example of the structure for fixing the lower housing half 12 and the upper housing half 14. FIG. 4A is different from the configuration shown in FIG. 1 in regard to the receiving structure of the head portion of the bolt 18 which is a fastening means in the upper flat plate portion 14a of the upper housing half 14, and is a portion of the through portion of the upper flat plate portion 14a. The bulging portion 102 is provided in the bulging portion 102, and the waterproof seal material 104 is interposed between the bulging portion 102 and the bolt head 18a. In this way, by bulging the part through which the bolt 18 penetrates, rainwater can flow to the other part of the upper flat plate part 14a and can be prevented from collecting in the vicinity of the penetration part. It should be noted that it is preferable that a similar bulging portion 106 is provided in the through portion of the lower housing half 12. As a result, even if rainwater enters the housing through the through portion of the upper housing half 14, the rainwater is guided to the bulging portion 106 and can be discharged outside through the through portion.

また、同図（Ｂ）は、上側ハウジング半体１４の上部平板部１４ａと下側ハウジング半体１２の支持平板部１２ａを貫通して締結するのではなく、接合屈曲部１４ａと支持平板部１２ａの部分で固定した例を示している。図示のように、接合屈曲部１４ａと支持平板部１２ａとを貫通する貫通孔を設け、その部分に一方側から装着作業のできるブラインドリベット１０８を用い、防水パッキン２６を介在させて固定を行っている。上述のように、本実施の形態では、締結手段の作用は、絶縁被覆導体１６の荷重等を支えるものではなく、それらを挟持し、上側ハウジング半体１４と下側ハウジング半体１２との位置決めを行うことで足りるので、このリベットによる接合屈曲部１４ｃでの固定で十分な強度を得ることが可能である。 In FIG. 5B, the joint bent portion 14a and the support flat plate portion 12a are not penetrated and fastened through the upper flat plate portion 14a of the upper housing half body 14 and the support flat plate portion 12a of the lower housing half body 12. The example fixed in the part is shown. As shown in the drawing, a through-hole penetrating the joint bending portion 14a and the support flat plate portion 12a is provided, and a blind rivet 108 that can be mounted from one side is used in that portion, and the waterproof packing 26 is interposed for fixing. Yes. As described above, in the present embodiment, the operation of the fastening means does not support the load of the insulation-coated conductor 16, but sandwiches them and positions the upper housing half 14 and the lower housing half 12. Therefore, sufficient strength can be obtained by fixing at the joint bent portion 14c by the rivet.

また、この構成によれば、上側ハウジング半体１４の上部平板部１４ａに貫通孔１４ｄが設けられないので、防水性はより高いものとなる。更に、上部平板部１４ａの上面に突出部がないのでバスダクト上を必要に応じて歩行する様な場合にもつまづきなどを防止することができ、作業の安全性の向上を図ることができる。 Moreover, according to this structure, since the through-hole 14d is not provided in the upper flat plate part 14a of the upper housing half body 14, waterproofness becomes higher. Further, since there is no protruding portion on the upper surface of the upper flat plate portion 14a, it is possible to prevent a tripping or the like when walking on the bus duct as necessary, and to improve the safety of work.

図１１は、上側ハウジング半体１４と下側ハウジング半体１２のバスダクト幅方向の長さの関係を種々変形した例を示している。同図（Ａ）は、上側ハウジング半体１４と下側ハウジング半体１２とを同一のサイズ、形状として形成している。これにより、部材の共通化による製造の容易化を図ることができる。 FIG. 11 shows examples in which the length relationship in the bus duct width direction of the upper housing half 14 and the lower housing half 12 is variously modified. In FIG. 2A, the upper housing half 14 and the lower housing half 12 are formed in the same size and shape. Thereby, the manufacture can be facilitated by sharing the members.

また、図１１（Ｂ）は、上側ハウジング半体１４の接合屈曲部１４ｃを更に伸長させ、上方にほぼ直角に立ち上げた立設部１４ｅを設けている。この立設部１４ｅの上端は上部平板部１２ａの裏面に接触もしくは近接する位置まで伸長している。これによって、締結手段（ボルト１８など）により締め付け固定する際のハウジング側の強度を増加させることができる。 Further, in FIG. 11B, the joining bent portion 14c of the upper housing half 14 is further extended, and an upright portion 14e that is raised substantially at a right angle is provided. The upper end of the standing portion 14e extends to a position in contact with or close to the back surface of the upper flat plate portion 12a. As a result, the strength on the housing side when tightening and fixing by the fastening means (bolt 18 or the like) can be increased.

図１１（Ｃ）は、上側ハウジング半体１４の側面カバー部１４ｂと下側ハウジング半体１２の支持脚部１２ｂの外側面が非面一となる構成を取っている。すなわち、本例では上側ハウジング半体１４の上部平板部１２ａが下側ハウジング半体１２の支持平板部１２ａよりも幅方向の長さが短く設定されている。また、図１２（Ａ）に示したように、逆に上部平板部４ａが支持平板部１２ａよりも幅方向の長さが長く設定することも可能である。また、このサイズの長短は、一方側の側面カバー部１４ｂと支持脚部１２ｂのみを面一の構成として、他方側を上述のようにずらすことも可能である。この様に、上側ハウジング半体１４と下側ハウジング半体１２の幅方向の長さは融通を持たせた設定とすることができる。 FIG. 11C shows a configuration in which the outer side surfaces of the side cover portion 14b of the upper housing half 14 and the support leg portion 12b of the lower housing half 12 are not flush with each other. That is, in this example, the upper flat plate portion 12 a of the upper housing half body 14 is set to have a shorter length in the width direction than the support flat plate portion 12 a of the lower housing half body 12. Further, as shown in FIG. 12A, the upper flat plate portion 4a can be set to have a longer length in the width direction than the support flat plate portion 12a. In addition, the size of this size can be shifted as described above, with only the side cover 14b and the support leg 12b on one side being flush with each other. In this way, the lengths in the width direction of the upper housing half 14 and the lower housing half 12 can be set so as to be flexible.

次に、図１２（Ｂ）は、締結手段であるボルト１８を上側ハウジング半体１４の接合屈曲部１４ｃにも貫通させた例を示している。この構成により上側ハウジング半体１４と下側ハウジング半体１２の固定状態の安定化を向上させることができる。 Next, FIG. 12B shows an example in which the bolt 18 as a fastening means is also passed through the joint bent portion 14 c of the upper housing half 14. With this configuration, stabilization of the fixed state of the upper housing half 14 and the lower housing half 12 can be improved.

次に、図１３は、バスダクト１０の接続部寄り位置に端部に設けられる端部板部の構成を図５、図６に示した構成と異なる構成にした例を接続部の領域を抜き出して示している。すなわち、上側ハウジング半体１４の端部から連続して延出させるのではなく、端部板部３５を上側ハウジング半体１４とは別体のものとして構成して取り付けたものである。更に、本例では、端部板部３５のバスダクト側端部に上部平板部１４ａの上面に沿った状態からほぼ直角に立ち上がった立ち上げ部３５ａが設けられている。これにより、上部平板部１４ａ側からの接続部への水が浸入を有効に防止することができる。なお、端部板部３５は、バスダクト側端部の上部平板部１４ａの上面に沿った部分で、締結手段１８，２０によって締結固定されている。 Next, FIG. 13 shows an example in which the configuration of the end plate portion provided at the end near the connection portion of the bus duct 10 is different from the configuration shown in FIGS. Show. That is, instead of continuously extending from the end portion of the upper housing half body 14, the end plate portion 35 is configured and attached as a separate body from the upper housing half body 14. Further, in this example, a rising portion 35a that rises substantially perpendicularly from the state along the upper surface of the upper flat plate portion 14a is provided at the end of the end plate portion 35 on the bus duct side. Thereby, it is possible to effectively prevent water from entering the connecting portion from the upper flat plate portion 14a side. The end plate portion 35 is a portion along the upper surface of the upper flat plate portion 14a at the end portion on the bus duct side, and is fastened and fixed by the fastening means 18 and 20.

また、上側ハウジング半体１４の端部には、上方に折り曲げた立ち上げ部１４ｆを設けており、接続部への水の侵入をより効果的に防止している。また、上部平板部１４ａの上面と端部板部３５の下面との間に、防水パッキンを設けてもよくより防水効果を高めることができる。 In addition, a rising portion 14f that is bent upward is provided at the end of the upper housing half 14 to more effectively prevent water from entering the connecting portion. Further, a waterproof packing may be provided between the upper surface of the upper flat plate portion 14a and the lower surface of the end plate portion 35, and the waterproof effect can be further enhanced.

以上、本発明を上記実施形態に基づいて説明したが、本発明は上記の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形が可能である。例えば、上下側ハウジング半体１４，１２は板部材を折り曲げ成形した場合について説明したが、これに限るものではなく、押し出し成形する場合であってもよい。また、上下側ハウジング半体１４，１２を予め塗装した鋼板を折り曲げ加工して形成する例を説明したが、上下側ハウジング半体１４，１２の加工後に塗装（防錆処理）を施すようにしてもよい。この場合、切断面も同時に塗装するのが好適である。 As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to said embodiment, A various deformation | transformation is possible within the range of the summary of invention. For example, although the case where the upper and lower housing halves 14 and 12 are formed by bending a plate member is not limited to this, it may be formed by extrusion. In addition, the example in which the upper and lower housing halves 14 and 12 are formed by bending a steel plate previously coated has been described. However, after the upper and lower housing halves 14 and 12 are processed, coating (rust prevention treatment) is performed. Also good. In this case, it is preferable to coat the cut surface at the same time.

更に、上側ハウジング半体１４及び下側ハウジング半体１２の切断面（接合屈曲部１４ｃ，設置屈曲部１２ｃの端面）が塗装されていない場合、切断面には別途、塗装（防錆処理）を施すのが好ましい。なお、接合屈曲部１４ｃ，設置屈曲部１２ｃが内側に曲げられている場合、それらの端面は、ハウジング内に収容されるので、風雨に晒されることはなく、切断面を塗装し直さなくても錆びることはないので、塗装の省略も可能である。 Further, when the cut surfaces of the upper housing half 14 and the lower housing half 12 (end surfaces of the joint bent portion 14c and the installation bent portion 12c) are not painted, a separate coating (rust prevention treatment) is applied to the cut surfaces. It is preferable to apply. In addition, when the joint bending part 14c and the installation bending part 12c are bent inside, since those end surfaces are accommodated in the housing, they are not exposed to wind and rain, and it is not necessary to repaint the cut surface. Since it does not rust, painting can be omitted.

なお、バスダクト設置作業の都合上、バスダクト幹線上を作業者等が歩く場合があるが、上記各実施の形態では、上側ハウジング半体１４及び下側ハウジング半体１２の両端がコ字形状に折り曲げられているので、単にＬ字形状に折り曲げた場合よりも直立状態の維持強度が増しており、別途、補強部材のような部材を設けなくても、バスダクトが撓んで変形したり、ハウジングがつぶれてしまうことが有効に防止されている。 For convenience of bus duct installation work, an operator or the like may walk on the bus duct main line. In the above embodiments, both ends of the upper housing half 14 and the lower housing half 12 are folded into a U-shape. Therefore, the maintenance strength of the upright state is increased as compared with the case where it is simply bent into an L-shape. Even if a member such as a reinforcing member is not provided separately, the bus duct is bent and deformed, or the housing is crushed. Is effectively prevented.

また、接続部における接続方式が突き合わせ方式である場合について説明したが、これに限られず、バスダクト同士の導体端部を重ね合わせて一括締結する重ね合わせ方式であってもよい。また、絶縁密着型バスダクトについて例示したが、これに限定するものではなく、裸導体を碍子等で支持し、空気絶縁する空気絶縁型バスダクトにおいても適用可能である。 Moreover, although the case where the connection method in a connection part is a butt | matching method was demonstrated, it is not restricted to this, The superposition method which piles up the conductor end part of bus ducts and may be fastened collectively may be sufficient. In addition, although the insulation contact type bus duct has been illustrated, the present invention is not limited to this, and the present invention can be applied to an air insulation type bus duct in which a bare conductor is supported by an insulator or the like and air is insulated.
