Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an inner door of a box for housing an electric device that covers various electric devices and wirings stored in a distribution board and the like.

[0002]

[Prior art]

 As shown in FIG. 5, the structure of the inner door of the electrical equipment housing box of the prior art is such that the inner board mounting bracket 22 is provided immediately below the opening edge 21a of the electrical equipment housing box 21 in the inner board mounting bracket 22. The column 23 is fixed, and a pillar 24 having a length from the inner machine mounting rail 23 to the vicinity of the opening edge 21a is erected, and an inner door 25 is provided at the upper end of the pillar 24.

However, there is a drawback that the wiring space 26 between the electric equipment housing box 21 and the support column 24 is very narrow. Therefore, when there are many wires to be wired, the support column 24 is deformed due to pressure on the wires. In addition, since there is no gap between the support column 24 and the opening end edge portion 21a, it is difficult to store the electric wire in the wiring space 26, and the wiring work is very difficult.

Therefore, in order to solve such a drawback, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 5-2510.

As shown in FIG. 6, the pillar 27 is formed in a substantially U shape so as to largely project to the side plate 21 b side of the box 21 for housing electric equipment, and the inner door 25 is provided at the upper end of the pillar 27. The electric wire is provided so that the space portion of the pillar 27 having a substantially U-shape serves as a wiring space 28.

[0006]

[Problems to be solved by the device]

 However, since the column 27 of FIG. 6 projects to the side plate 21b side more than the opening end edge 21a, the frame 29 or the column 27 must be removed once when the internal unit is taken out from the electrical equipment housing box 21. In addition to this, since the shape of the support column 27 becomes complicated, the support column 27 needs to be reinforced, and the cost of manufacturing the support column 27 increases. Further, since the column 27 is also formed in a substantially U shape, the wiring work is easy, but the wiring space 28 is not wide enough.

Therefore, the present invention provides a structure of an inner door of a box for storing an electric device, which is easy to perform wiring work and take-out work of an internal unit and can be manufactured at low cost.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the structure of the inner door of the box for storing electric equipment according to the present invention is such that the inner door is divided into a first inner door and a second inner door, and the first inner door is at least an electric one. A first hinge is provided on the inner edge of the first inner door that covers one of the peripheral edges of the left and right sides of the device storage box, and the first inner door on the first hinge side. The second inner door is provided with a second hinge facing the first hinge at one end of the left and right edges, and the first hinge and the second hinge are hinged respectively.

A first inner door is provided at each end of the second inner door, and the first and second inner doors are hingedly attached to each other, and the first and second inner doors can be detachably attached to each other. It is provided with a locking means.

The first inner door on the first hinge side on the back surface of the first inner door is provided with a strut mounting bracket.

[0011]

[Action]

 When performing the wiring work, if the first inner door fixed to the pillar is removed, a gap is formed between the opening edge of the box for storing electrical equipment and the upper end of the pillar, and the wire is delivered through the gap. The wiring of the operator.

[0012] When a strut mounting bracket is provided near the first hinge on the back surface of the first inner door, the strut mounting bracket fixed to the strut by opening the second inner door when performing wiring work. Remove the first inner door to perform wiring work.
