Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power distribution panel in which a ventilation fan can be easily mounted with a simple structure.

[0002]

2. Description of the Related Art A conventional example of a ventilation fan for a switchboard will be described with reference to FIG. In this figure, the ceiling plate 1 of the box-type switchboard
A ventilation fan 2 supported by a box-shaped support 3 is attached to the ventilation port 2 with a plurality of screws 5. The ventilation fan 4 is attached to the ceiling plate 1 after connecting the lead wire 7 to the power supply via the relay connector 6, and in this state, a closing plate 8 using a wire mesh is attached to the ceiling plate 1 from the outside of the ventilation fan 4 by a plurality of screws. 9 is attached.

[0003]

In the above structure, the screws 5,
Not only does the number of required parts such as 9 increase, but there is a drawback that a lot of trouble is required for removing and reattaching the ventilation fan 4 at the time of inspection or the like.

[0004] In order to eliminate the above-mentioned disadvantages, the present invention provides:
An object of the present invention is to provide a ventilation fan for a switchboard which can be easily attached and detached with a simple structure.

[0005]

According to the present invention, in order to achieve the above object, a ventilation box 12 is provided in a box-shaped switchboard, and a support plate 13 of a ventilation fan 4 is connected to the ventilation port 12 with a hinge 14. A female or male conductive terminal 15 is attached to the outer surface of the anti-hinge side edge of the ventilation port 12, and a male or female ventilation fan terminal 16 that can be easily inserted into and removed from the terminal 15 is provided on the inner surface of the support plate 13. It is intended to be attached.

[0006]

The terminals 15 and 16 are for connecting the lead wire 7 of the ventilation fan 4 to the power supply via the terminals 15 and 16, and the supporting plate 13 of the ventilation fan 4 is hinged to the ventilation port 12 to reduce the number of required parts. A simple structure allows easy attachment and detachment, and the terminal 1 is connected to the ventilation port 12 and the support plate 13.
When the support plates 13 are attached, the lead wires 7 can be automatically connected to the power supply when the support plates 13 are attached.

[0007]

FIG. 1 shows an embodiment of the present invention.
Those indicated by the same reference numerals are the same parts. This figure shows the process of installing the ventilation fan 4 and the ceiling panel 1 of the box-type switchboard.
1 is provided with a rectangular ventilation port 12, and a support plate 13 of the ventilation fan 4 is connected to the ventilation port 12 with a hinge 14.
The ventilation fan 4 has an outer frame formed integrally with the support plate 13,
The outer surface of the ventilation fan 4 is closed by attaching a wire mesh (not shown) to the support plate 13. An opening / closing operation handle 17 is provided on the outer surface of the support plate 13. A female conductive terminal 15 is mounted on the outer surface of the anti-hinge side edge of the ventilation port 12, and a male ventilation fan terminal 16 which can be easily inserted into and removed from the terminal 15 is mounted on the inner surface of the support plate 13. ing.
The terminals 15 and 16 are for connecting the lead wire 7 of the ventilation fan 4 to a power source via the terminals. When the support plate 13 is closed in the direction of the arrow, it is connected as shown in FIG. It connects automatically. In this state, the support plate 13 is fixed to the ceiling plate 11 with screws 9.

In the above embodiment, the female terminal 15 is
Although the case of mounting has been described, the present invention can also be implemented by mounting the male terminal 16 on the ceiling plate 11 and the female terminal 15 on the support plate 13, respectively.

[0009]

According to the present invention, in the ventilation fan of the switchboard, the support plate of the ventilation fan is hingedly connected to the ventilation port provided in the box-type switchboard, so that it can be easily attached and detached with a simple structure requiring a small number of parts. In addition, a conductive terminal and a ventilation fan terminal which can be easily inserted into and detached from this terminal are attached to the ventilation opening and the support plate, respectively, so that the lead wire of the ventilation fan is automatically connected to the power supply with the attachment of the support plate. The effect that it can be obtained is obtained.
