本考案は配電盤等の母線支持に用いる導体支持
具に関するものである。[Detailed Description of the Invention] The present invention relates to a conductor support used for supporting busbars of switchboards, etc.
例えば、配電盤の側壁に母線を貫通させた場

の、あるいは第３図及び第４図に示すように本体
２０に加えて母線１０を固定する一対のＬ形金具
３０を設けたものがある。 For example, when a busbar is passed through the side wall of a switchboard, the busbar is supported at the penetrating portion, and a conductor support having an insulating tube is used to shorten the distance between the phases. As shown in FIGS. 1 and 2, the support tool consists of a single main body 20, which is formed by integrally molding protective insulating cylinders 23 and 24 on both sides of a support substrate 22 with a through hole 21 for the bus bar 10 in the center, back to back. Alternatively, as shown in FIGS. 3 and 4, in addition to the main body 20, a pair of L-shaped fittings 30 for fixing the bus bar 10 are provided.

破壊されるおそれがある。 The former supports the bus bar 10 at the through hole 21, and the latter supports the bus bar 10 by fixing the L-shaped fitting 30 to the board 22 with bolts 31 and nuts 32, and using the rivet 33 to support the bus bar 10.
0, but both are integrated with the bus bar through hole 21
The size and direction of the bus are constant, and it cannot accommodate changes in bus bar dimensions due to differences in current capacity or changes in bus bar installation direction. Therefore, it is necessary to prepare a large number of types with matching dimensions and directions, and various molds can be used. The cost increases due to the need for molds and other expenses. In addition, in the former case, depending on the place of use, there is a risk that the support may be destroyed by the mechanical force of the busbar generated during a short circuit.

体支持具を提供することを目的とする。 The present invention was made in view of the above points, and by providing a cross-shaped bus bar through hole of the maximum dimension of the support bus bar in the support board, and providing a long board mounting hole in the L-shaped metal fitting, various dimensions can be obtained. The purpose of the present invention is to provide a conductor support that can be used for busbars.
以下、本考案を図示の実施例に基づいて詳細に
説明する。 Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

うに設けてある。即ち、l1＝l2とする。 5 to 11 show an embodiment of the present invention, in which 10 is a busbar, 20 is a support body, and 30 is a busbar fixing fitting (L-shaped fitting). The main body 20 has protective insulating tubes 23 on both sides of a support substrate 22, as in the conventional case.
24 are integrally molded, and a cross-shaped generatrix through hole 25 is bored in the center of the substrate 22. The dimensions t and w of the through hole 25 are selected to correspond to the thickness and width of the largest generatrix line to be supported. Further, holes 26 for fixing the bus bar fixing fittings 30 are provided so as to be located at each corner of the regular quadrilateral. That is, l 1 =l 2 .
一方、母線固定金具３０はその一面に母線固定

の寸法ｌは固定用の孔２６の間の寸法と等しく、
つまりｌ＝l1＝l2となるように選定されている。 On the other hand, the bus bar fixing fitting 30 is provided with a hole 35 on one side for inserting the bus bar fixing bolt 34, and a long hole 36 for inserting the bolt 31 for fixing the metal fitting 30 on the board 22 on the other side. ing. The elongated hole 36 is formed in such a shape that the dimension a between its two centers is at least 1/2 the difference between the maximum and minimum thickness of the generatrix, and its long axis is formed to be perpendicular to the surface that joins with the generatrix. There is. Further, the dimension l between the two elongated holes 36 is equal to the dimension between the fixing holes 26,
In other words, they are selected so that l=l 1 =l 2 .
なお、３２，３７はボルト３１，３４と螺合す
るナツトである。 Note that 32 and 37 are nuts that are screwed together with the bolts 31 and 34.

から挾持するように取付ければよい。 An example of the busbar support state is shown in Fig. 10 and Fig. 1.
The result will be as shown in Figure 1. That is, the generatrix 10 is supported horizontally and held between the L-shaped fittings 30 from above and below. In this case, a part of the elongated hole 36 is connected to the hole 26.
Since they always match, the attachment to the substrate 22 is ensured, and the hollow part of the cross-shaped through hole 25 is also hidden. Such attachment can be carried out regardless of bus bar size. Also, the installation direction of the bus bar 10 is 90
In the case of rotation, the L-shaped fittings 30 may be attached so as to sandwich the generatrix from the lateral direction.
