Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a structure for mounting an inner door in an inner unit of a box for storing electrical equipment such as a switchboard, a distribution board and a control panel. Here, the internal unit refers to a structure including a panel fixed to a rail or a bottom plate, internal electric equipment such as a breaker attached to the panel, and an inner door.

[0002]

[Prior Art]

 Conventionally, the mounting structure of the middle door for covering the inner unit of the box for storing electrical equipment such as a switchboard, a distribution board, a control panel, etc. is usually one for opening or closing the middle door. Two or more stanchions were attached to the sides, and the base ends of the stanchions were attached to the inner bottom of a rail or a bottom plate of a box for housing electrical equipment. Then, as shown in Fig. 4 (A), the middle door is divided from the outer door of the distribution board according to the components that are unitized for each function of the internal unit. ing. In addition, there is no mechanism to bind and fix the wires around the stanchions, even though the wires from the internal machine such as a circuit breaker always pass through, so bypass the mounting structure as shown in Fig. 4 (B). The wires were bundled and fixed by inserting the mounting structure between the wires.

[0003]

[Problems to be solved by the device]

 However, when installing the internal machine, the number of upright columns will increase, and it will take time and effort to bundle and fix the wires so that they do not get in the way of many columns. If a large-diameter wire or the like is hooked on the pillar, or if it is pressed by a curved wire, an excessive load is applied to the pillar, causing the pillar to be deformed or damaged. Even so, the pillars were often deformed and could not be attached.

[0004]

[Means for Solving the Problems]

 In order to reduce the number of columns of the inner door of the above conventional storage box and to eliminate the problem of distortion occurring in the columns, the present invention has a simple structure and is convenient for attaching and detaching internal equipment. The present invention provides a mounting structure for a middle door of a box body, and the structure is such that in the mounting structure for mounting the middle door to the inner bottom of the box for storing electrical equipment, at least two or more parts are attached to the edge of the middle door. A mounting part, a erection part that laterally installs the mounting part, a base part that is attached to the inner bottom of an electrical equipment storage box, an electrical equipment storage box that connects the erection part and the base part. It is composed of a column body having at least one bent portion provided with a convex portion in the side plate direction of the body. Here, the mounting portion, the erected portion, the base portion or the pillar body may be integrally configured by an arbitrary combination, and the mounting member may be a hinge that can be opened or closed or a screw that can be fixed to the middle door of the middle machine. .

[0005]

[Action]

 With the above-described mounting structure provided on the bottom of the storage box body, the number of bases mounted on the inner bottom of the electrical equipment storage box can be made smaller than the number of mounting sections by way of the erection section. A wiring space is created on the inner machine side of the bent part of the top and column, and electric wires can be bundled and fixed there, so deformation and damage due to electric wire hooking and accompanying rattling of built-in middle door are prevented. To be done.

【Example】

 A mounting structure for a middle door of a box for housing an electric device according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of an embodiment of a mounting structure of a middle door of the present invention, FIG. 2 is a sectional view thereof, 1 is a distribution board which is a box for storing electrical equipment, 2 is its door, and 3 is It is an inner door for covering wiring. Reference numeral 4 is a rail which is arranged in parallel on both sides of the bottom plate and has an opening having a U-shaped cross section facing downward, and a breaker 5 is installed between the rails. Depending on the type of housing for electrical equipment, rails may not be provided and it may be fixed directly to the bottom plate, so it is widely called the inner bottom. Two mounting portions 6 are rotatably supported on the end edge 3a of the middle door 3 by a shaft (not shown), and the mounting portions 6 are laterally installed on an installation portion 7 parallel to the rails 4.

Reference numeral 10 is a pillar for attaching the middle door 3 to the rail 4 of the distribution board, and includes a base portion 8 screwed to the rail 4 and a pillar body 9 for fixing the end portion of the erection portion 7 at the upper end. It is formed integrally. The pillar 9 is formed in an L shape having one bent portion 9a provided with a convex portion toward the side plate 1a of the distribution board 1, and the outer side surface thereof contacts the side plate 1a. An electric wire 11 from the breaker 5 is arranged in a space formed in a U shape by the mounting portion 6 and the column 10. The shape in which the protrusion is provided on the side plate 1a of the distribution board 1 of the pillar body 9 may be a U-shape having two bent portions or an arc shape having one bent portion that bends as a whole. Then, the inner door 3 is attached to the attaching portion 6 by a hinge so as to be openable and closable. This attachment method not only makes it possible to open and close the inner door as in the embodiment, but also attaches the inner door 3 with a screw. The inner door may be fixed by screwing. The relationship between the mounting positions of the mounting portion 6 and the base portion 8 is larger than that of the opening of the distribution board 1 because the mounting position of the inner unit 5 and the size of the inner door 3 enhance the convenience of the mounting work. Therefore, the mounting portion 6 is provided at a position above the base 8 in the opening direction of the distribution board so that the middle door 3 can be smoothly opened and closed.

FIG. 3 is an explanatory view of another embodiment of the mounting structure of the middle door of the present invention, and FIG. 3A shows the middle door 3 attached to the erection portion 7 attached to the upper end of the pillar 10 of the above embodiment. Is attached by a screw which is the mounting portion 6. Further, in (B), an insertion hole 3b corresponding to the mounting portion 6 is formed in the end edge 3a of the middle door 3, and a round bar-shaped installation portion 7 is loosely inserted in the insertion hole 3b to attach the installation portion 7 to the installation portion 7. The center door 3 is rotatable around the center. The upper end of the pillar 10 is extended in the same direction as the base portion 6, the pillar 10 has a U-shaped cross section, and the erection portion 7 is pivotally supported at the end of the elongated pillar 10. There is. Reference numeral 7a is a spacer for holding the space between the inner doors 3. In addition, although the present embodiment describes the case where two mounting structures are used in the distribution board, it is also applicable to the case where three or more mounting structures are used in a large storage box or the like. Besides, the present invention can be applied not only to the distribution board but also to all electrical equipment housing boxes that require a bundling / fixing of internal electric wires using a mounting structure.

[0009]

[Effects of the Invention] With the mounting structure of the inner door of the box for storing electrical equipment according to the present invention, the number of bases mounted on the inner bottom of the box for storing electrical equipment can be adjusted by the installation section. In addition to being able to reduce the number of wires, wiring space has been created, wiring work has become easier, and workability has been dramatically improved.In addition, the wired wires will not come into contact with the mounting structure, and electrical equipment can be stored due to deformation of the mounting structure. There is no distortion of the box body, and the actual profit is enormous.
