Abstract: A protector structure for an inverter 1 which is an example of an electrical component includes a protector 3 including a protection portion 31, an attachment portion 32A and an attachment portion 32B. The protector 3 has a constricted portion 33A between the protection portion 31 and the attachment portion 32A, and has a constricted portion 33B between the protection portion 31 and the attachment portion 32B.

Abstract: An inverter includes a case, and the case includes an upper case and a lower case attached to a bottom surface side of the upper case. The upper case includes a flange portion constituting an attachment portion of the lower case, and a connector connecting portion to which a connector is connected. The connector connecting portion includes an outer wall portion that forms an outer wall of the connector connecting portion. At least a part of the flange portion and at least a part of the outer wall portion are disposed so as to overlap each other in a direction in which the connector connecting portion and the structure face each other.

Abstract: A stator structure of a rotary electric machine includes a stator, a motor power distribution component installed in the stator, and a casing that houses the stator and the motor power distribution component. The motor power distribution component has a terminal block inserted into an opening formed in a side wall of the casing. A lead wire connects a sensor installed in the stator to a connector electrically connecting the sensor to an external component. The lead wire is inserted into a gap between an edge of the opening and the terminal block.

Abstract: A power transmission device for an electrically driven vehicle basically includes a power transmission mechanism, a sliding contact brush, a brush case cover, and a brush protective jig. The power transmission mechanism includes a case element, an axle element and a power transmission element. The sliding contact brush is mounted on an axle end of the axle element. The brush case cover is selectively mounted to the case element to enclose the axle end of the axle element in the case element. The brush protective jig is mounted to cover the brush contact when mounting the sliding contact brush to the axle end. The brush protective jig is dimensioned to contact the brush case cover and to prevent the brush case cover from being mounted to the case element while the brush protective jig is in an attached state that covers the brush contact.

Abstract: In a structure for a motor or generator, stator segments have a toothed portion to receive a coil. A busbar is electrically connected to the coil, and an insulator has a coil insulator portion disposed between the toothed portion and the coil and a busbar insulation portion insulatedly supporting the busbar.
