Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for a control device such as an inverter control device, which is capable of reducing radiation noise generated at the time of switching operation of a semiconductor element accompanying inverter control.

[0002]

2. Description of the Related Art In recent years, the development of electronic technology has been remarkable, and electronic circuits are incorporated not only in electronic information processing apparatuses such as computers but also in all kinds of electronic equipment and medical equipment used at home. In addition, the influence of external radiation noise may cause malfunction of these electronic devices. Thus, such a situation would have a significant social impact.

As a semiconductor element used for inverter control, a transition has been made from a thyristor to a transistor to an IGBT, and high-speed switching of the element has become possible. The control performance is improved by reducing the switching loss and downsizing the inverter control device and increasing the carrier frequency.

[0004] With the high-speed switching of semiconductors, dV / dt during switching sharply increases. Accordingly, leakage current increases due to stray capacitance existing between the device or the power supply and the ground, and equipment malfunction may occur due to conduction noise. A countermeasure against this conduction noise is taken by inserting a noise filter in the power supply line.

[0005]

When dV / dt occurs during switching of the semiconductor element of the inverter control device housed in the housing, radiation noise is radiated into the air. Therefore, when there is a gap in the housing of the inverter control device, the radiated noise is emitted outside through the gap. Also, if the contact between the metal of the panel and the housing of the inverter control device is not substantially 0Ω, a resistance value is generated on the contact surface, and the potential difference between the ground due to dV / dt generated in the inverter control device; A difference occurs in the potential difference of the panels generated through the resistance surface, and a leakage current of a commercial frequency flows between them. At this time, radiation noise may be emitted through the panel surface. The radiated noise may cause a malfunction of the device as described above.

For this reason, conventionally, as a method of reducing radiation noise to the outside of the control device, a door panel, a side panel, and a ceiling panel of the control device housing are used in order to make the entire control device housing have the same voltage (ground). In order to make the same potential between the panels by reducing the resistance of the housing of the inverter control device and the panels, the contacting parts of the back panel are subjected to plating treatment and painting masking treatment, and they are closely connected to each other.
I have taken measures against radiation noise. However, in such a case, the painting and plating work becomes complicated, and the material of the panel is restricted, so that the cost is increased, the design is restricted, the delivery is delayed, and the panel configuration is complicated. was there.

[0007] In view of the above, the present invention does not impair the effect of reducing radiation noise from control equipment such as an inverter control device, and reduces the coating and plating processes.
An object of the present invention is to provide a storage device for a control device such as an inverter control device, which mainly improves workability, simplifies a panel configuration, and improves appearance.

Bending part 2 of door panel 20a
4), an S-shaped shield clip 25 made of a conductive member is attached.

When the left door panel 20a and the right door panel 20b are closed, the shield clip 25 comes into close contact with the non-painted surface of the other door panel. Therefore, the left door panel 20a, the right door panel 20b, and the angle frame 1 are sufficiently conductive, and each of them has almost zero electric resistance and is made to have the same potential.

In the above embodiment, the door panel is constituted by two sheets. However, the door panel may be constituted by two or more sheets.

FIG. 24 is a view showing another embodiment of the present invention, in which one housing is closely mounted on another housing. That is, the side panels of the adjacent housings 26a and 26b,
In a, the right side panel is eliminated, and in the storage device 26b, the left side panel is eliminated, and a non-painted (plated) inter-housing panel 27 is interposed therebetween so as to be connected to each other.

FIG. 25 is a partial cross-sectional view of the connecting portion. The inter-housing panel 27 is made of a member having the same thickness as the side panel 2, and a bending process slightly smaller than the width of the angle frame 1 is performed. The rear panel 4, the angle frame 1, and the inter-housing panel 27 are in close contact with each other. In addition, the angle frames 1 of the housings 26a and 26b and the inter-housing panel 27 are fixed by connecting bolts 28 so as to be in close contact with each other.

Thus, the two frames 26a, 26b, the angle frame 1 and the rear panel 4 can be sufficiently conducted by the inter-frame panel 27.

FIG. 26 is a view showing a method of painting the panel. As shown by the hatched portion in FIG. 27, a masking 29 is applied to the back side end of the panel 28 to be painted only on the front side, and the front side is painted. The paint is applied by the spray 30.
As a result, it is possible to prevent the paint from wrapping around the back side edge as shown by the oblique lines in FIG.

That is, if a portion of the paint is applied to a portion where the conduction is originally required, the panel cannot be attached in close contact due to the thickness of the paint, and the electrical resistance becomes slightly high, and the radiation noise increases. The effect of prevention is weakened. However, by performing the above-described treatment, there is no influence of unevenness in the painting operation, and thus the original conductivity can be reliably ensured.

[0050]

Since the present invention is constructed as described above, it is possible to hide a non-painted portion for the purpose of conduction of an angle frame or the like without performing an extra paint treatment for cutting off a part of the function. , Can improve the appearance. Further, in achieving the same potential as the housing, the painting masking work for the back, side, and ceiling panels is reduced, workability is improved, and costs can be reduced.
