High voltage electrical packaging box structure

摘要

A high voltage electrical packaging box structure includes a box body, and a high voltage electric part which is accommodated in the box body. In the high voltage electrical packaging box, an interposing member which is formed using an expandable resin, is disposed between the box body and the high voltage electric part. Air may be passed through the inside of the box body so as to cool down the high voltage electric part placed in the box body.
