Description

[0001]
[Industrial application fields]
In a distribution board in which electrical equipment such as a breaker is placed in a box having an opening on the front surface, and the opening of the box can be covered with a wiring cover, a charging unit comprising a main bar connecting the electric equipment and a main bar fixing part Related to the structure.
[0002]
[Prior art]
As shown in FIGS. 3 to 4, the distribution board 31 according to the prior art places electrical devices such as a breaker 33 on a box 32, and the breaker 33 is connected by a copper bar 34. The charging part composed of the copper bars 34 is supported by a main bar fixing part 35. The main bar fixing part 35 forms a main bar fixing part 36, and the copper bar 34 is placed on the main bar fixing part 36, respectively. It was fixed.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, the main bar fixing part 35 has a function and a shape only for fixing the copper bar 34, and foreign matters such as dust falling from the upper part of the distribution board 31 are caused by the main bar fixing part. There was an accident that entered through the gap 37 of the 35 and short-circuited between the different phases of the main bar, and there was a risk of fire.
[0004]
[Means for Solving the Problems]
In view of the above problems, an object of the present invention is to provide a main bar fixing part that has a simple structure and prevents intrusion of foreign matters such as dust and has improved safety. It is characterized in that the main bar fixing parts that support the main bar arranged in the vertical direction that is the vertical direction are arranged on the upper and lower surfaces of the charging unit, forming a fixing part and a wall part that closes the gap between the main bar. To do.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The main bar fixing component according to the present invention is provided with a wall portion in addition to the main bar fixing portion, and the main bar is placed and fixed on the main bar fixing portion, and dust falling from the upper part of the distribution board by the wall portion. This prevents foreign matter such as the intrusion into the live part and enhances the safety of the distribution board.
[0006]
【Example】
An embodiment of a distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
Distribution board 1 according to the present invention, placing the electrical device such as a breaker 2 inside the back of the box having an open front surface serving as a front opening, may be covered with wire cover, connect the electrical device The charging unit 4 including the main bar 3 is supported by the main bar fixing component 5 with the main bar 3 arranged in the vertical direction which is the vertical direction .
[0008]
A main bar fixing part 6 and a wall part 7 are formed on the main bar fixing part 5. The main bar fixing parts 5 are disposed at least on the upper and lower surfaces of the charging unit 4, and the main bar fixing unit 6 mounts and fixes the R-phase bar 3a, the S-phase bar 3b, and the T-phase bar 3c, respectively.
[0009]
The upper and lower surfaces of the charging portion are protected by the wall portion 7 of the main bar fixing component 5. Therefore, it is possible to prevent foreign matters such as dust falling from the upper part of the distribution board from entering the charging unit.
[0010]
The main bar fixing component according to the present invention is not limited to the above method of use. For example, a protrusion is provided at the tip of the main bar fixing component, and the wiring covering or the load name writing plate is supported by the protrusion. Or the wall portion of the main bar fixing component can be formed in a net shape, or can be appropriately changed without departing from the gist of the present invention.
[0011]
【The invention's effect】
As described above, the main bar fixing part according to the present invention forms the main bar fixing part and the wall part closing the gap between the main bars in the main bar fixing part, and is arranged in the vertical direction which is the vertical direction. Since the main bar fixing parts that support the main bar are placed on the upper and lower surfaces of the charging unit, the upper and lower surfaces of the charging unit are protected by the wall, so that foreign matter such as dust is less likely to enter the charging unit, resulting in a short-circuit accident. Generation can be prevented and the safety of the distribution board can be improved.
