Power converting apparatus

摘要

A power converting apparatus includes a housing, a cable, and a grommet supporting member. The housing includes a housing base, a main body, and an air duct. The housing base has a first surface and a second surface and includes a through hole. The main body includes a plurality of electronic components on the first surface of the housing base. The air duct is disposed on the second surface of the housing base, and cooling air flows through the air duct. The cable is disposed through the through hole of the housing base so as to be wired between the main body and the air duct. The grommet supporting member is in the air duct or the main body. The grommet supporting member supports a grommet through which the cable is disposed. The grommet supporting member is not integral with the housing base.

主权项

1. A power converting apparatus configured to convert alternating current power into direct current power or convert direct current power into alternating current power, the power converting apparatus comprising:
a housing comprising:
a housing base having a first surface and a second surface and comprising a through hole;a main body comprising a plurality of electronic components on the first surface of the housing base; andan air duct through which cooling air flows on the second surface of the housing base; a cable disposed through the through hole of the housing base so as to be wired between the main body and the air duct; and a grommet supporting member in at least one of the air duct or the main body, the grommet supporting member supporting a grommet through which the cable is disposed, the grommet supporting member being not integral with the housing base, wherein the grommet supporting member comprises:
a holder through which the grommet is disposed so as to hold the grommet, the holder comprising a close contact portion extending parallel to and in close contact with a circumference of the through hole of the housing base; anda gasket disposed on the close contact portion at a location sandwiched between the close contact portion and the circumference of the through hole of the housing base.
