Abstract

A vehicle auxiliary machine having an inverter circuit includes an inverter cover, an inverter cover fastening member, an interlock plate and an interlock switch mechanism. The inverter cover covers the inverter circuit. The inverter cover fastening member is provided for fastening the inverter cover to the vehicle auxiliary machine. The interlock plate covers the inverter cover fastening member and is detachably fastened to the inverter cover. The interlock switch mechanism is operable in accordance that the interlock plate is removed from a predetermined position of the inverter cover.

Description

Technical field [0001] The invention relates to a vehicle auxiliary machine with an inverter circuit. Background technique [0002] Japanese Patent Application Publication No. 2004-190547 discloses an electric compressor having an inverter. The electric compressor has an inverter circuit on its shell, and the inverter circuit is encapsulated on the compressor by means of an inverter cover (or cover). Once the compressor is installed on the vehicle, maintenance services such as inspection and replacement of the inverter circuit are carried out together with the compressor installed on the vehicle. Since the inverter circuit has a part that generates high voltage, maintenance personnel must be very careful not to touch the inverter circuit during maintenance work. [0003] On the other hand, Japanese Utility Model Application Publication No. 59-99660 discloses a generator that has an openable protective cover in which a terminal attached to the generator is enclosed, and the cover ...
