Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a switchboard busbar that connects end portions of opposing busbars horizontally arranged in each switchboard of two adjacent switchboards.

[0002]

[Prior art]

 As shown in Fig. 4, a conventional switchboard busbar is installed with the switchboards 1 and 2 adjacent to each other, and the busbars 3 and 4 supported by an insulating support (not shown) are horizontally arranged in the switchboard. It The connecting conductors 5 and 6 are sandwiched between the opposite ends of the bus bar, and the bolts and nuts 8 are tightened and fixed.

[0003]

[Problems to be solved by the device]

 In the assembling work of the switchboard bus thus configured, the switchboard 1 and the switchboard 2 are installed side by side, and the connecting conductors 5 and 6 are applied by straddling the opposite ends of the busbars 3 and 4, and the bolts are installed. 7. The nuts are tightened and fixed with nuts 8, and it is necessary to secure a space for the connecting conductors 6 and hold and tighten each connecting conductor. Also, the nuts must be held with a tightening tool, and the nuts must be engaged from the back side of the busbars and tightened by turning the bolts with a tightening tool from the front side, which complicates the work. This proposal was made to solve the above problems, and its purpose is to enable easy tightening and fixing from the front side of the busbar.

[0004]

[Means for Solving the Problems]

 A busbar is horizontally arranged in each switchboard of two adjacent switchboards, and in a switchboard busbar in which the ends of opposing busbars are connected by connecting conductors, the busbars are provided in the switchboard and the ends are arranged close to the side plates. And the connecting conductors that are attached across the opposite busbar ends, and the supporting pieces that hold the busbars and connecting conductors at the upper and lower sides of the rectangular support plate and project in the direction perpendicular to the supporting plate. A claw that protrudes in parallel to the support plate and contacts the bus bar or the plate surface of the connecting conductor inside, and has a claw that protrudes upward at one end of the lower supporting piece and engages with the end surface of the connecting conductor. And a holder with a nut fixed to the back surface of the support plate.

[0005]

[Action]

 Therefore, slide the holder that supports the connecting conductor and is held at the end of the busbar on one side in the direction of the end of the busbar on the other side so that it straddles the opposite busbar ends, and tighten the bolts from the front side of the busbar. Fix it.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a top view showing a cross section of a main part, FIG. 2 is a front view of a holder, and FIG. 3 is a cross sectional view taken along the line AA of FIG. The same parts as those in FIG. 4 are designated by the same reference numerals and detailed description thereof will be omitted. Reference numeral 9 denotes a holder, which is provided with support pieces 11 and 12 projecting perpendicularly to the support plate at the upper and lower ends of the rectangular support plate 10, and a busbar and a connecting conductor are provided between the support pieces on the plate surface of the support plate. They are placed side by side in parallel. Locking pieces 13 and 14 are provided inside the ends of the supporting pieces so as to project in a direction parallel to the supporting plate. A claw portion 15 protruding upward is provided at one end of the lower support piece 14, and an end face of the connection conductor is in contact with this claw portion. Reference numeral 16 is a nut fixed to the back surface of the support plate 10 by welding or the like. Therefore, when assembling the switchboard and transporting the switchboard, the holder supporting the connecting conductor at the busbar end of one switchboard was fixed to the busbar end, and the switchboards were installed in rows at the installation location. After that, slide the holder that supports the connecting conductor and is held at the end of the busbar on one side in the direction of the end of the busbar on the other side so that it straddles the opposite busbar ends, and tighten the bolts from the front side of the busbar. To fix.

[0007]

[Effect of device]

 As described above, according to this plan, one person works from the front side, which simplifies connection work and works in one direction on the front side, so that the back side can be installed along a wall, etc., and the installation space can be reduced. Has the effect of.
