Abstract

This terminal mounting structure is provided with: a plurality of recipient-side terminals (19) extending from respective distal ends of electrical leads (171); a mount (42) having an electrically insulating base material (43) and a plurality of supply-side conductive bars (44) that are disposed at an interval from one another and extend through the base material; a plurality of screws (48) that are screwed into screw holes formed in ends of the supply-side conductive bars through the recipient-side terminals in a direction intersecting with the direction of extension of the recipient-side terminals, thus fixedly contacting each of the recipient-side terminals to the respective corresponding supply-side conductive bars; and a contact prevention mechanism (46) that is provided to the mount and prevents contact between adjacent recipient-side terminals.

Description

technical field [0001] The present invention relates to a motor drive device for a vehicle that drives wheels of an electric vehicle or a hybrid vehicle, and more particularly to a structure in which a terminal of a motor coil is attached to a conductive rod on the power supply side inside the motor drive device for a vehicle. Background technique [0002] As an in-wheel motor drive device arranged in the road wheel internal space region of the wheel, or as an on-vehicle motor drive device mounted on the vehicle body and drives the wheel through a drive shaft, in the prior art, for example, JP 2010-2010 is known. 172069 Publication (Patent Document 1) discloses a motor drive device for a vehicle. A motor drive device for a vehicle, such as an in-wheel motor drive device or an on-vehicle motor drive device, is connected to a cable extending from the outside of the vehicle motor drive device, and receives electric power supplied through the cable. [0003] However, the intern...
