Structure for connecting electrodes of motor unit and motor driver unit.

摘要

The present invention relates to a structure for connecting electrodes of a motor unit and a motor driver unit which is a power circuit for the motor unit in an electric power drive vehicle, so that the motor unit and the motor driver unit are electrically connected to each other. The structure includes: electrode terminals (31) to which a coil of the motor unit is connected and which are provided with fixing nuts; substantially L-shaped electrode plates (28) each formed at one end with a terminal portion (37) connected to the inverter circuit (4) and at the other end with a contact portion (35) to which the electrode terminal (31) is connected, the contact portion being formed with an insertion hole (34); L-shaped resin electrode bases (29) for attaching the electrodes plates (28) to a metallic frame (21) under an insulated condition, each of the electrode bases including an elongated hole (39) for attaching a bolt to be engaged with the insertion hole (34) of the electrode plate and a guide groove (43) for preventing the electrode plate (28) from rotation; and bolts (33) each extending through the elongated hole of the electrode base so as to connect the electrode terminal (31) to the electrode plate (28).
