用機器の手前側に保護板が設けられている。2. Description of the Related Art A distribution board, for example, a low-voltage distribution board, is constructed by accommodating distribution equipment such as a main breaker and a branch breaker. In such a switchboard, a protective plate is provided on the front side of the power distribution device when the outer door is opened.

器の取り付けや、配線、あるいは、その後の保守点検等
にあたっては、保護板を開けて行う。Here, the protective plate is supported by four pillars projecting from the board bottom toward the four corners.
One end side of the protective plate corresponds to this so that the protective plate can be opened by rotating to the front from either the left or right side in the board width direction.
It is attached to the column of the book via a hinge. On the other hand, the other end of the protective plate is closed by screwing a knurled screw from the front side of the holding plate to the nuts provided on the two corresponding columns in the closed state of the protective plate. The holding plate can be opened and the knurled screw can be removed from the nut to open the holding plate. When the holding plate is closed, the operating portion of the power distribution device is exposed from the protective plate, and the operating portion can be operated from the front side of the protective plate. When installing the power distribution equipment on the power distribution board, wiring, or performing subsequent maintenance inspections, open the protective plate.
【0004】ところで、保護板の裏側の配電盤内では、
配電用機器の左右両側に、ガタースペースが設けられ、
ガタースペースは、配線スペースとされる。By the way, in the switchboard on the back side of the protective plate,
Gutter spaces are provided on both left and right sides of the power distribution equipment,
The gutter space is a wiring space.

ースペース内に入り込んでその一部を専有しており、配
線スペースがその分狭くなり、配線作業も面倒である。
配線スペースを広げようとすれば、配電盤は、大型化が
避けられない。Conventionally, the support columns for supporting the protective plate enter the gutter space and occupy a part thereof, so that the wiring space becomes narrower by that amount and the wiring work is troublesome.
If the wiring space is to be expanded, the switchboard is inevitably increased in size.
【0006】また、保護板の一端側はヒンジを介して支

ーレットねじとの軸方向を一致させるのに、支柱側と保
護板側と間の位置決めに高い寸法精度が求められる。Further, since one end side of the protective plate is attached to the supporting column via a hinge, in order to make the axial direction of the nut and the knurled screw coincide with each other on the other end side of the protective plate, a gap between the supporting column side and the protective plate side is set. High dimensional accuracy is required for positioning.
