The wiring duct 4 has an opening 43 into which the plug portion 52 and the fixing portion 53 are inserted, a groove portion 42 to be fitted, and a power supply line 41 that is electrically connected to the plug portion 52 and supplies power. .

図4は、プラグ部52を斜め上方から見た図である。プラグ部52は、配線ダクト4の長手方向に対する平行位置Aと直交位置Bとに矢印Cに示すように回動自在で、配線ダクト4の溝部42に嵌合する略四辺形上のプラグ回転板52aと、プラグ回転板52aと共に回動し、配線ダクト4の電源ライン41と電気接続される2枚の電気接続端子板52bと、プラグ回転板52aと電気接続端子板52bとを回動させるレバー52cを有している。安定器収納部本体54にはストッパー52dが設けられており、レバー52cの回転範囲を制限している。プラグ部52を配線ダクト4に取り付けるときは、まず、プラグ回転板52aの長手方向を平行位置Aに合わせる。続いて、プラグ部52を配線ダクト4の開口部43に挿入し、レバー52cを回してプラグ回転板52aの長手方向が直交位置Bの位置になるように回動し、プラグ回転板52aを溝部42に嵌合させて配線ダクト4に取り付ける。このとき、電気接続端子板52bも一緒に回動し電源ライン41に電気接続される。   FIG. 4 is a view of the plug portion 52 as viewed obliquely from above. The plug portion 52 is rotatable at a parallel position A and an orthogonal position B with respect to the longitudinal direction of the wiring duct 4 as indicated by an arrow C, and is a substantially quadrangular plug rotating plate that fits into the groove portion 42 of the wiring duct 4. 52a, a lever that rotates together with the plug rotation plate 52a and rotates the two electrical connection terminal plates 52b electrically connected to the power supply line 41 of the wiring duct 4, and the plug rotation plate 52a and the electrical connection terminal plate 52b 52c. The ballast housing part main body 54 is provided with a stopper 52d, which limits the rotation range of the lever 52c. When attaching the plug portion 52 to the wiring duct 4, first, the longitudinal direction of the plug rotating plate 52 a is aligned with the parallel position A. Subsequently, the plug portion 52 is inserted into the opening 43 of the wiring duct 4, and the lever 52c is rotated so that the longitudinal direction of the plug rotation plate 52a is at the position of the orthogonal position B, so that the plug rotation plate 52a is grooved. 42 is fitted to the wiring duct 4. At this time, the electrical connection terminal plate 52b also rotates together and is electrically connected to the power supply line 41.

図5は、固定部53を斜め下方から見た図であり、図6は、配線ダクト4に嵌合された固定部53を下方から見た図であり、図7は、固定部53を配線ダクト4に取り付ける動作を説明する図である。固定部53は、平行位置Aと直交位置Bとに矢印Dに示すように回動自在で、配線ダクト4の溝部42に嵌合する固定部回転板53aを有している。固定部回転板53aは、操作ネジ53bを回すことにより回動する。固定部回転板53aは略四辺形状で、回動可能なように角が丸みを持った曲部53cを有している。また、固定部回転板53aには、切り欠き部53eが設けられており、安定器収納部本体54の回転ストッパー53fによって、逆方向への回動が防止されている。   5 is a view of the fixing portion 53 as viewed from obliquely below, FIG. 6 is a view of the fixing portion 53 fitted to the wiring duct 4 as viewed from below, and FIG. It is a figure explaining the operation | movement attached to the duct 4. FIG. The fixed portion 53 has a fixed portion rotating plate 53 a that is rotatable between a parallel position A and an orthogonal position B as indicated by an arrow D and that fits into the groove portion 42 of the wiring duct 4. The fixed portion rotating plate 53a rotates by turning the operation screw 53b. The fixed portion rotating plate 53a has a substantially quadrilateral shape and has a curved portion 53c with rounded corners so that it can rotate. Further, the fixed portion rotating plate 53a is provided with a notch 53e, and the rotation stopper 53f of the ballast housing portion main body 54 prevents rotation in the reverse direction.

固定部53を配線ダクト4に取り付けるときには、図7に示したように、固定部回転板53aの長手方向を平行位置Aに合わせて、固定部53を配線ダクト4の開口部43に挿入した状態から、操作ネジ53bを矢印D方向に回して、固定部回転板53aの長手方向を直交位置Bに合わせる。このとき、固定部回転板53aの曲部53cは丸みを持っているので、溝部42の内幅に干渉されることなく回動させることができるが、直交位置Bにまで回動させると、溝部42の内幅に干渉される。さらに、固定部回転板53aを回動させようとしても、曲部53cに隣接した角部53dが溝部42の内幅に当接して回動範囲が制限される。こうして、固定部53は配線ダクト4に嵌合し取り付けられる。   When the fixing portion 53 is attached to the wiring duct 4, as shown in FIG. 7, the fixing portion 53 is inserted into the opening 43 of the wiring duct 4 with the longitudinal direction of the fixing portion rotating plate 53a aligned with the parallel position A. Then, the operating screw 53b is turned in the direction of arrow D, and the longitudinal direction of the fixed portion rotating plate 53a is adjusted to the orthogonal position B. At this time, since the curved portion 53c of the fixed portion rotating plate 53a has a roundness, the curved portion 53c can be rotated without being interfered with the inner width of the groove portion 42. It is interfered with the inner width of 42. Furthermore, even if it is going to rotate the fixed part rotation board 53a, the corner | angular part 53d adjacent to the curved part 53c contact | abuts to the inner width of the groove part 42, and the rotation range is restrict | limited. Thus, the fixing portion 53 is fitted and attached to the wiring duct 4.

スポットライト1を配線ダクト4に取り付けるときには、プラグ部52を取り付けてから固定部53を取り付けてもよいし、固定部53を取り付けてからプラグ部52を取り付けてもよい。また、同時に取り付けてもよい。   When the spotlight 1 is attached to the wiring duct 4, the fixing portion 53 may be attached after the plug portion 52 is attached, or the plug portion 52 may be attached after the fixing portion 53 is attached. Moreover, you may attach simultaneously.

上述した本実施形態によれば、スポットライト1は、プラグ部52と固定部53とによって配線ダクト4の溝部42に嵌合して取り付けられるので、堅牢に取り付けることができる。また、プラグ部52と固定部53のどちらからでも取り付けることができるので、取り付け性がよい。また、プラグ部52の取り付けによって電気接続もできるので、取り付け作業が容易になる。   According to the above-described embodiment, the spotlight 1 can be securely attached because the plug portion 52 and the fixing portion 53 are fitted and attached to the groove portion 42 of the wiring duct 4. Moreover, since it can attach from either the plug part 52 or the fixing | fixed part 53, attachment property is good. Further, since the electrical connection can be made by attaching the plug portion 52, the attaching operation becomes easy.

なお、本発明は、上記各種実施形態の構成に限られず、発明の趣旨を変更しない範囲で種々の変形が可能である。例えば、固定部回転板53aにレバーを取り付けて、レバーによって固定部回転板53aを回動してもよい。   In addition, this invention is not restricted to the structure of the said various embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, a lever may be attached to the fixed portion rotating plate 53a, and the fixed portion rotating plate 53a may be rotated by the lever.
