Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring cover for covering an internal wiring space of an equipment storage box used for a distribution board, a distribution board, or the like.

[0002]

2. Description of the Related Art For example, a device storage box used for a distribution board is designed to prevent a worker from accidentally coming into contact with a charged part of a device such as a main switch or a circuit breaker provided in the box. In addition, as shown in FIG. 3, a wiring cover having a window 1 (hatched portion in the figure) formed at a location corresponding to the device is provided on the entire surface of the opening of the box, and only a portion such as a switch of the device is exposed from the window. ing. By doing so, it is possible to operate the installed equipment without removing the wiring cover.

[0003]

However, although the description of the device exposed in the window portion and the name of the load connected to the device are displayed on the wiring cover by a seal or the like, the connection of each device is performed. The figures were rarely displayed, and even in rare cases, very small stickers were attached to the back of the wiring cover. Therefore, it was difficult to read even if the connection diagram was attached, and the size and arrangement of the device of the connection diagram and the device of the distribution board were different, making it difficult to collate. Therefore,
In view of the above problems, an object of the present invention is to provide a wiring cover of a device storage box having a connection diagram that is easy to see and use.

[0004]

In order to solve the above-mentioned problems, a first aspect of the present invention is to provide a device having a window covering a front opening of a device storage box and exposing at least a part of the front surface of the stored device. A wiring cover of a storage box, wherein a line serving as a wiring diagram is displayed between the windows so as to indicate a connection state of the device.

A second aspect of the present invention is characterized in that, in the first aspect of the invention, a symbol of a device to be exposed from the window is displayed in the middle of a line connecting the windows.

According to a third aspect of the present invention, in the first or second aspect of the present invention, a connection state on a secondary side of the device exposed from the window is displayed at a position close to the window. I do.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an example of a wiring cover of a device storage box according to the present invention, and shows a wiring cover that covers a front opening of a distribution board. In this wiring cover, a plurality of windows 1 (1a, 1b, 1c) are formed at predetermined positions by pressing a metal plate.
In the figure, reference numeral 1a denotes a window of a main switch having an electric light as a load, and 1b denotes a window of a power main switch. Also, 1
c is a window of a circuit breaker for each wiring path connected to the output side of the main switch of the light. The windows 1 are used as they are as the symbols of the devices in the connection diagram, and
Indicates the knot wiring status. In addition, a seal indicating the name of the load connected to the secondary side is attached to a predetermined position on either side of the window 1 or on the upper or lower side. The line representing the wiring may be affixed in a seal shape, may be formed by directly printing it together with the load name, or may be handwritten.

As described above, by using the window portion 1 as it is as the symbol of the device and displaying the wiring, the connection state can be understood at a glance without separately checking the circuit diagram, and the maintenance and inspection can be easily performed. it can. In addition, there is no possibility of making a mistake in wiring at the time of extension work or the like.

FIG. 2 shows another embodiment of the wiring cover. In FIG. 2, in addition to displaying the connection state between the devices, the device symbol is displayed in the middle of the wiring immediately before or immediately after the window 1, the primary connection location of the main switch is displayed, and the branch device is further displayed. Displays the connection status of the equipment connected to the secondary side. In addition, 3 is the symbol of the main switch, and 4 is the symbol of the circuit breaker for wiring. By displaying the power supply side connection location of the internal equipment and the connected secondary side connection status in this way, the connection status inside and outside the distribution board can be grasped at a glance, and the connection around the distribution board was included. Maintenance inspection can be performed easily.

In the above-described embodiment, the connection diagram is displayed only on the front surface of the wiring cover. However, a similar display or a part of the display may be displayed on the rear surface. Even if the wiring cover has a door-like opening / closing structure, it is easy to check the wiring. Further, the wiring cover is formed by processing a metal plate, but may be formed by a resin plate or the like. In addition, although the distribution board has been described, the invention can also be effectively applied to a box for storing other electric devices.

[0011]

As described in detail above, according to the present invention,
Since the wiring is displayed using the window as it is as a symbol of the device, the connection state can be understood at a glance without separately checking the circuit diagram, and maintenance and inspection can be easily performed.
