Claims

[Scope of utility model registration request]

The inside of the box-shaped panel frame is partitioned vertically into multiple levels by shelf boards to form multiple unit chambers, and units with various instruments attached are stored in each of these unit chambers in a freely insertable and removable manner. In a device configured to move a contact provided on the back of the unit and a bus bar in the panel frame toward and away from each other by movement along a direction, a contact member provided on the back of the unit and a bus bar in the board frame is provided between the bus bar and the unit, covering the bus bar and facing the bus bar. An insulating cover having an opening at a certain position is provided, and a movable shield plate is provided along the surface of the insulating cover, and the shield plate engages with a drive pin provided on the unit to move the unit in the drawing direction. A drive plate having a slit that moves the shield plate to a position where the opening of the insulating cover is closed and a position where the opening of the insulation cover is opened is integrally provided, and the direction in which the shield plate opens the opening of the insulation cover is integrally provided. A closed switchboard characterized by being provided with a return spring that applies force in the direction of return when the switchboard is moved.
