　固定部１５は、レール１１の第１の位置に移動部１２を固定している第１状態（図１～図４参照）と、移動部１２をレール１１に固定していない第２状態（図５参照）と、Ｘ方向において第１の位置とは離れたレール１１の第２の位置に移動部１２を固定している第３状態（図６参照）と、を切り替え可能である。 The fixed part 15 has two states: a first state in which the moving part 12 is fixed to the first position of the rail 11 (see FIGS. 1 to 4), and a second state in which the moving part 12 is not fixed to the rail 11 (see FIGS. 5) and a third state (see FIG. 6) in which the moving part 12 is fixed at a second position of the rail 11 that is apart from the first position in the X direction.
　固定部１５は、例えば複数の固定部１５Ａ及び複数の固定部１５Ｂを有している。複数の固定部１５Ａの各々は、第１貫通孔１１Ｃ１及び１つの第３貫通孔１２Ａ４に通される軸部を有するボルトと、当該軸部に締結されるナットとを含む。複数の固定部１５Ｂの各々は、第２貫通孔１１Ｃ２及び１つの第４貫通孔１２Ｂ４に通される軸部を有するボルトと、当該軸部に締結されるナットとを含む。 The fixing part 15 includes, for example, a plurality of fixing parts 15A and a plurality of fixing parts 15B. Each of the plurality of fixing parts 15A includes a bolt having a shaft portion passed through the first through hole 11C1 and one third through hole 12A4, and a nut fastened to the shaft portion. Each of the plurality of fixing parts 15B includes a bolt having a shaft portion passed through the second through hole 11C2 and one fourth through hole 12B4, and a nut fastened to the shaft portion.
　第１状態及び第３状態では、固定部１５Ａのボルトがナットと締結されており、固定部１５Ｂのボルトがナットと締結されている。第１状態から第２状態への切り替え、及び第３状態から第２状態への切り替えは、固定部１５Ａのボルトとナットとの締め付けを緩めるとともに、固定部１５Ｂのボルトとナットとの締め付けを緩めることにより、実現される。第２状態において、移動部１２は、支持部１３とともに、レール１１に沿ってＸ方向にスライド可能である。第２状態における移動部１２及び支持部１３のＸ方向への移動距離は、第１貫通孔１１Ｃ１及び第２貫通孔１１Ｃ２の各々のＸ方向の開口幅以下である。第２状態から第３状態への切り替えは、固定部１５Ａのボルトとナットとを締め付けるとともに、固定部１５Ｂのボルトとナットとを締め付けることにより、実現される。 In the first state and the third state, the bolt of the fixed part 15A is fastened to the nut, and the bolt of the fixed part 15B is fastened to the nut. Switching from the first state to the second state and switching from the third state to the second state are performed by loosening the bolts and nuts of the fixed part 15A and loosening the bolts and nuts of the fixed part 15B. This is achieved by: In the second state, the moving part 12 is slidable along the rail 11 in the X direction together with the supporting part 13. The moving distance of the moving part 12 and the supporting part 13 in the X direction in the second state is equal to or less than the opening width of each of the first through hole 11C1 and the second through hole 11C2 in the X direction. Switching from the second state to the third state is achieved by tightening the bolts and nuts of the fixed part 15A and also by tightening the bolts and nuts of the fixed part 15B.
　第２状態において、移動部１２をＸ方向にスライドさせる前に、支持部１３の着脱部１３Ｂが本体部１３Ａから取り外されてもよい。この場合、移動部１２をＸ方向にスライドさせた後、第２状態から第１状態に切り替えられ、さらにその後に、着脱部１３Ｂが本体部１３Ａに取り付けられてもよい。あるいは、移動部１２をＸ方向にスライドさせた後、着脱部１３Ｂが本体部１３Ａに取り付けられ、さらにその後、第２状態から第１状態に切り替えられてもよい。いずれの場合にも、第２状態では、リード線３０を支持している支持部１３のＸ方向における位置が変更され得る。 In the second state, the detachable part 13B of the support part 13 may be removed from the main body part 13A before the moving part 12 is slid in the X direction. In this case, after sliding the moving part 12 in the X direction, the second state may be switched to the first state, and then the detachable part 13B may be attached to the main body part 13A. Alternatively, after sliding the moving part 12 in the X direction, the detachable part 13B may be attached to the main body part 13A, and then the second state may be switched to the first state. In either case, in the second state, the position of the support part 13 supporting the lead wire 30 in the X direction can be changed.
　このように、リード支持装置１によれば、リード線３０を支持している支持部１３がレール１１に対して固定されていない第２状態を実現でき、第２状態ではリード線３０を支持している支持部１３のＸ方向における位置を変更可能である。そのため、リード支持装置１がリード線３０を支持可能な位置の自由度は、特許文献１に記載のリード支持装置と比べて、高い。 In this way, according to the lead support device 1, it is possible to realize the second state in which the support part 13 supporting the lead wire 30 is not fixed to the rail 11, and in the second state, the support part 13 supporting the lead wire 30 is not fixed to the rail 11. The position of the supporting portion 13 in the X direction can be changed. Therefore, the degree of freedom in the position where the lead support device 1 can support the lead wire 30 is higher than that of the lead support device described in Patent Document 1.
　また、リード支持装置１では、第２状態において、支持部１３はＸ方向への移動のみが許容されており、Ｙ方向及びＺ方向への支持部１３の移動は制限されている。そのため、リード支持装置１によってリード線３０を変圧器本体２０に対して位置決めする作業では、作業者は主にＸ方向における支持部１３の位置を調整すれば足りるため、作業効率が高い。 Further, in the lead support device 1, in the second state, the support portion 13 is only allowed to move in the X direction, and movement of the support portion 13 in the Y direction and the Z direction is restricted. Therefore, in the work of positioning the lead wire 30 with respect to the transformer main body 20 using the lead support device 1, the worker only needs to adjust the position of the support part 13 mainly in the X direction, so the work efficiency is high.
　また、リード支持装置１は、移動部１２に回転自在に支持されている転動体１４Ａ，１４Ｂを備え、第２状態において、転動体１４Ａ，１４Ｂは、レール１１上をＸ方向に転動可能である。そのため、転動体１４Ａ，１４Ｂを備えないリード支持装置と比べて、移動部１２及び支持部１３はレール１１に沿って滑らかにスライド可能である。 Further, the lead support device 1 includes rolling elements 14A and 14B that are rotatably supported by the moving part 12, and in the second state, the rolling elements 14A and 14B can roll on the rail 11 in the X direction. be. Therefore, the moving part 12 and the support part 13 can slide smoothly along the rail 11 compared to a lead support device that does not include the rolling elements 14A and 14B.
　また、リード支持装置１は、例えばＺ方向が上下方向に沿っておりかつ軌道部１１Ｂが連結部１１Ａよりも下方に配置されるように、変圧器本体２０に対して固定され得る。この場合、転動体１４Ａ及び転動体１４Ｂの各々が、レール１１の軌道部１１Ｂよりも上方に位置する移動部１２の第１部分１２Ａ又は第２部分１２Ｂに回転自在に支持されている。そのため、転動体１４Ａ及び転動体１４Ｂの各々が、移動部１２、支持部１３、及びリード線３０の荷重を受けることができる。 Furthermore, the lead support device 1 may be fixed to the transformer main body 20 such that, for example, the Z direction is along the vertical direction and the track portion 11B is disposed below the connecting portion 11A. In this case, each of the rolling elements 14A and 14B is rotatably supported by the first portion 12A or the second portion 12B of the moving portion 12 located above the track portion 11B of the rail 11. Therefore, each of the rolling elements 14A and 14B can receive the loads of the moving part 12, the supporting part 13, and the lead wire 30.
　なお、リード支持装置１は、例えばＺ方向が上下方向と交差するように、変圧器本体２０に対して固定されていてもよい。 Note that the lead support device 1 may be fixed to the transformer main body 20, for example, so that the Z direction intersects with the up-down direction.
　リード支持装置１では、転動体１４Ａ及び転動体１４Ｂを構成する材料が耐熱性樹脂であるため、転動体１４Ａ及び転動体１４Ｂの経年劣化が抑制されている。 In the lead support device 1, since the material constituting the rolling elements 14A and 14B is a heat-resistant resin, aging deterioration of the rolling elements 14A and 14B is suppressed.
　実施の形態２．
　図７に示されるように、実施の形態２に係るリード支持装置２は、リード支持装置１と基本的に同様の構成を備え同様の効果を奏するが、レール１１の軌道部１１Ｂに複数の第１貫通孔１１Ｃ１及び複数の第２貫通孔１１Ｃ２が形成されている点で、リード支持装置１とは異なる。 Embodiment 2.
As shown in FIG. 7, the lead support device 2 according to the second embodiment has basically the same configuration as the lead support device 1 and has the same effects, but a plurality of grooves are provided on the track portion 11B of the rail 11. This differs from the lead support device 1 in that a first through hole 11C1 and a plurality of second through holes 11C2 are formed.
　複数の第１貫通孔１１Ｃ１は、Ｘ方向において互いに間隔を空けて配置されている。複数の第２貫通孔１１Ｃ２は、Ｘ方向において互いに間隔を空けて配置されている。複数の第１貫通孔１１Ｃ１の各々は、複数の第２貫通孔１１Ｃ２と、Ｙ方向に並んで配置されている。言い換えると、Ｙ方向に並んで配置されている１つの第１貫通孔１１Ｃ１と１つの第２貫通孔１１Ｃ２とにより構成される１組の貫通孔が、複数組形成されている。 The plurality of first through holes 11C1 are arranged at intervals in the X direction. The plurality of second through holes 11C2 are arranged at intervals in the X direction. Each of the plurality of first through holes 11C1 is arranged in line with the plurality of second through holes 11C2 in the Y direction. In other words, a plurality of sets of through holes are formed, each consisting of one first through hole 11C1 and one second through hole 11C2 arranged in the Y direction.
　複数の第１貫通孔１１Ｃ１及び複数の第２貫通孔１１Ｃ２の各々の開口形状は、例えば円形状である。 The opening shape of each of the plurality of first through holes 11C1 and the plurality of second through holes 11C2 is, for example, circular.
　リード支持装置２では、リード線３０を支持している支持部１３が、複数組の貫通孔のうちいずれか１組の貫通孔とＺ方向に重なる位置に固定され得る。そのため、リード支持装置２がリード線３０を支持可能な位置の自由度は、特許文献１に記載のリード支持装置と比べて、高い。 In the lead support device 2, the support part 13 supporting the lead wire 30 can be fixed at a position overlapping in the Z direction with any one set of through holes among the plurality of sets of through holes. Therefore, the degree of freedom in the position where the lead support device 2 can support the lead wire 30 is higher than that of the lead support device described in Patent Document 1.
　他方、リード支持装置２がリード線３０を支持可能な位置の自由度は、リード支持装置１がリード線３０を支持可能な位置の自由度よりも低くなる。 On the other hand, the degree of freedom of the position where the lead support device 2 can support the lead wire 30 is lower than the degree of freedom of the position where the lead support device 1 can support the lead wire 30.
　複数の第１貫通孔１１Ｃ１及び複数の第２貫通孔１１Ｃ２の各々の内周面には、ネジ溝が形成されていてもよい。この場合、固定部１５Ａ及び固定部１５Ｂの各々は、複数の第１貫通孔１１Ｃ１及び複数の第２貫通孔１１Ｃ２の各々の内周面と螺合するボルトのみによって構成されていてもよい。 A thread groove may be formed on the inner peripheral surface of each of the plurality of first through holes 11C1 and the plurality of second through holes 11C2. In this case, each of the fixing part 15A and the fixing part 15B may be configured only by a bolt that is threaded into the inner circumferential surface of each of the plurality of first through holes 11C1 and the plurality of second through holes 11C2.
　＜変形例＞
　実施の形態１，２に係るリード支持装置１，２は、Ｘ方向から視て、連結部１１ＡのＹ方向の中心線に対して線対称の構造を有しているが、これに限られるものではない。リード支持装置１，２は、Ｘ方向から視て、連結部１１ＡのＹ方向の中心線に対して非対称の構造を有していてもよい。Ｘ方向から視て、レール１１の外形状は、例えば略Ｌ字形状又は略Ｊ字形状であってもよい。 <Modified example>
The lead support devices 1 and 2 according to Embodiments 1 and 2 have a structure that is line symmetrical with respect to the center line in the Y direction of the connecting portion 11A when viewed from the X direction, but the structure is not limited to this. isn't it. The lead support devices 1 and 2 may have an asymmetric structure with respect to the center line of the connecting portion 11A in the Y direction when viewed from the X direction. When viewed from the X direction, the outer shape of the rail 11 may be approximately L-shaped or approximately J-shaped, for example.
　例えば、図８に示されるように、レール１１は、転動体１４のＹ方向への移動を制限し転動体１４をＸ方向に案内するための凸部１１Ｅをさらに有していてもよい。凸部１１Ｅは、例えば転動体１４と第４対向部分１２Ｂ２との間に配置されている。なお、凸部１１Ｅは、転動体１４と第３対向部分１２Ｂ１との間に配置されていてもよい。 For example, as shown in FIG. 8, the rail 11 may further include a convex portion 11E for restricting movement of the rolling element 14 in the Y direction and guiding the rolling element 14 in the X direction. The convex portion 11E is arranged, for example, between the rolling element 14 and the fourth opposing portion 12B2. Note that the convex portion 11E may be arranged between the rolling element 14 and the third opposing portion 12B1.
