Abstract

A connection structure for an automotive power conversion device, wherein the connection structure comprises a housing for the power conversion device, an electrical connection part that is mechanically connected to the housing and performs an electrical connection between the power conversion device and an external device, and a conductor that electrically connects the power conversion device andthe electrical connection part, the housing and the electrical connection unit being mechanically connected via an antivibration structure, and the conductor being flexible so as to be capable of following the relative displacement of the housing and the electrical connection part.

Description

technical field [0001] The present invention relates to a connection structure suitable for a vehicle-mounted power conversion device. Background technique [0002] A vehicle using an electric motor as a power source is equipped with a power conversion device such as an inverter or a converter to drive the electric motor with electric power from a battery. In these power conversion devices, regarding the reliability of the electrical connection to the battery or the motor, it is necessary to fully consider the mechanical damage in the connection part due to external force such as vibration when the vehicle is running, and the damage caused by the intrusion of moisture or conductive foreign matter. Poor conduction caused by insulation breakdown, etc. [0003] For such a power conversion device, especially when it is installed in an engine room with severe vibration conditions, in many cases, a vibration-proof structure is used for the mechanical connection part with the vehi...
