[Industrial applications]

 TECHNICAL FIELD The present invention relates to an improvement of a pillar of an inner door in an inner unit of a box body for storing electrical equipment such as a distribution board, 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 devices such as a breaker attached to the panel, and an inner door.

[0002]

[Prior Art]

 Conventionally, the pillar 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 used to open or close the middle door, and is usually one side of 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 the rail or the bottom plate of the electrical equipment housing box. And, although there was no mechanism for bundling and fixing the wires around the stanchion, even though the electric wires that came out from the internal machine such as the breaker always passed, there was no mechanism to tie or fix the electric wires, as shown in Fig. 4. The wires were bundled and fixed by inserting columns between them.

[0003]

[Problems to be solved by the device]

 However, the method of binding and fixing the wires is troublesome and workable because it is designed so as not to interfere with the support, and the support was not specially reinforced. In the case of being pressed, an excessive load was applied to the stanchions, and the stanchions were deformed and damaged, or the stanchions could not be installed due to deformation of the stanchions even if the middle door was once removed and then re-installed. .

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem of the distortion of the pillars of the inner door of the storage box, the present invention has a simple structure and is convenient for attaching and detaching the internal machine, and the pillars are not distorted for storing electrical equipment. It provides a pillar for the middle door in the inner unit of the box.The structure is such that the middle door of the middle unit is attached to the inner bottom of the box for storing electrical equipment. Part, a base part to be attached to the inner bottom of the electrical equipment storage box, and a pillar connecting the mounting part and the base part, and the electrical equipment storage box from the base part. The mounting portion is provided on the upper side, which is the direction of the opening, and at least one bent portion is provided on the column in the side plate direction of the box for housing the electric device. The attachment part attached to the middle door of the middle machine may be openable / closable or fixed via a hinge.

[0005]

[Action]

 Due to the above-structured support pillars standing upright on the bottom of the storage box, a wiring space is created on the inner machine side of the bent portion of the pillar body, and wires can be bound and fixed there, so deformation and damage due to electric wire hooking Also, it is possible to prevent rattling when the inner door is opened.

[0006]

【Example】

 An embodiment of a pillar of a middle door of a box for housing an electric device according to the present invention will be described with reference to the drawings. 1 and 2 are explanatory views of the pillars of the inner door of the present invention, in which 1 is a distribution board which is a main body of a storage box, 2 is its door, and 3 is an inner door for covering wiring. Reference numeral 4 denotes rails that are arranged in parallel on both sides of the bottom plate and have openings with a U-shaped cross section facing downward, and a breaker 5 is installed between the rails. Depending on the type of box for storing electrical equipment, rails may not be installed and it may be fixed directly to the bottom plate, which is widely referred to as the inner bottom.

Further, on the rail 4, a column 6 is erected upright, which is composed of a column 6c, a mounting portion 6a provided on the head thereof, and a base portion 6b at the lower end thereof. The mounting portion 6a is provided above the base portion 6b in the direction of the opening of the distribution board 1. The mounting positions of the mounting portion 6a and the base portion 6b may be such that the mounting position of the inner unit and the size of the inner door are larger than the opening of the distribution board 1 due to the convenience of the mounting work. It is decided because there is no.

Therefore, in the pillar body 6c, the base portion 6b fixed to the rail 4 and the mounting portion 6a are on the same normal line with respect to the normal line direction of the bottom plate of the distribution board 1. The distribution board 1 is formed in a U shape having two bent portions 6d and 6d so as to largely project toward the side plate 1a, and the electric wire 7 is arranged in the space portion of the U shape. There is. The shape of this column 6c may be a dogleg shape having one bent portion as shown in FIG. 3 (A) or an arc shape having one bent portion as a whole as shown in FIG. 3 (B). Good. Then, the middle door 3 is attached to the attachment portion 6a by a hinge so as to be openable and closable. In this mounting method, not only the inner door can be opened and closed as in the embodiment, but also the inner door 3 may be screwed to fix the inner door.

In this embodiment, the case where two columns are used in the distribution board has been described, but it is also applicable to the case where three or more columns 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 bundling and fixing of internal wiring by using columns.

[0010]

[Effect of the device]

 The pillar of the inner door of the box for storing electrical equipment according to the present invention creates a wiring space, which facilitates the wiring work and significantly improves the workability. In addition, the wire that has been wired does not come into contact with the pillar and the pillar is deformed. As a result, the box for storing electrical equipment will not be distorted, and the actual benefit will be enormous.
