Abstract

A connection structure of a power conversion device, which is a connection structure of a vehicle-mounted power conversion device, comprising: a frame of the power conversion device; an electrical connection part, which is mechanically connected to the frame and used for power conversion The electrical connection between the device and the external device; and the conductor, the conductor electrically connects the power conversion device and the electrical connection part, the frame body and the electrical connection part are mechanically connected via an anti-vibration structure, and the conductor has the ability to follow the frame body and the electrical connection part. The flexibility of the relative displacement of the joint.

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...
