BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductor supporting device for supporting a main bar in a distribution board or the like.

[0002]

2. Description of the Related Art Generally, in a distribution board, a main bar having different plate thicknesses is used depending on the capacity of the main bar. For this reason, the upper surface of the main bar has different heights depending on the capacity, which causes inconvenience in connection with the standard branch breaker. For this reason, conventionally, as shown in FIGS. 8 and 9, a base 53a in which the mounting portion 54 of the conductor supporting device 51 of the base 53 is recessed by a press by a thickness corresponding to the difference in plate thickness is prepared. There is a problem that it is necessary to properly use the two types of conductor supporting devices 51 having different heights depending on the plate thickness.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, uses a common base and conductor supporting device, and changes the mounting method to increase the supporting height of the main bar. The purpose of the invention is to provide a conductor supporting device that can be adjusted.

[0004]

A first invention made in order to solve the above problems is to project a plurality of height adjusting short legs at asymmetrical positions on the lower end surface of the conductor supporting body. In addition to being provided, the base is provided with a through hole for fitting the short leg portion. A second invention made to solve the same problem is to project a plurality of short leg portions for height adjustment at an asymmetrical position of the lower end surface of the auxiliary support table inserted into the lower surface of the conductor support body. In addition, the base is provided with a through hole for fitting the short leg portion.

[0005]

In the first invention, the conductor supporting body is at a lower position when the height adjusting short leg is fitted in the through hole formed in the base, and when the conductor supporting body is rotated by 180 °, for example. The short leg for height adjustment is disengaged from the through hole formed in the base, and the conductor supporting body is positioned higher by the height of the short leg. Therefore, if the height of the short legs is made equal to the plate thickness difference of the main bar, the height of the upper surface of the main bar for 100A and the main bar for 200A can be changed only by changing the mounting of the conductor supporting body. Can be equal. Further, in the second invention, the same effect as the first invention can be obtained only by changing the mounting direction of the auxiliary support table inserted into the lower surface of the conductor supporting body.
