[Industrial applications]

 The present invention relates to an improvement in a fixing structure of an inner door, which is a wiring cover for covering an inner unit of a distribution board. Here, the internal unit refers to a structure including a panel fixed to a rail or a bottom plate and internal electric devices such as a breaker attached to the panel.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, conventionally, as shown in FIG. 4, the inner door of the distribution panel is fixed to cover the breaker 3 which is the inner unit of the distribution panel except for the switches and the like. There were two or more fixing columns 14 on the side of the door 7, and the base ends of the fixing columns 14 were attached to the rail 2 or the bottom plate 1 of the distribution board. In addition, in order to divide the inner door 7 according to the unitized components for each function of the inner unit such as the circuit breaker 3, the outer door 5 of the distribution board is one, but a plurality of outer doors 5 are provided. The fixing columns 14 are erected according to the number of the inner doors 7. Then, the electric wires 15, 15 extending from the circuit breaker 3 were passed through the gap between the fixing column 14 and the side plate 4 of the distribution board.

[Problems to be solved by the device]

 However, when attaching the inner unit to the rail or the bottom plate of the distribution board, the pre-fixed fixing posts interfere with the work, and conversely, attach the inner unit to bundle and fix the wires and then fix the Since the internal unit and the bundled and fixed electric wires interfere with the mounting of the columns, the workability is poor and the workability is poor. Even after mounting the internal units, wires and fixing columns, the conventional one-dot chain line is shown in Fig. 4. When a large-diameter electric wire is hooked on the fixing column as shown in, and the curved wire is pressed toward the inner door, an excessive load is applied to the fixing column, and the fixing column is deformed or damaged. Even if the inner door was once removed and then reattached, the fixing column was often deformed and could not be attached. In addition, it was necessary to prepare fixing columns with different lengths according to the height from the opening of the distribution board. Therefore, the present invention provides a fixing structure for an inner door of a distribution board in which an inner door is attached to an opening peripheral plate which is a peripheral portion of an opening to which an outer door of the distribution board is attached.
