Abstract: A cover assembly for on-board electric equipment includes a cover body and a connector including a terminal and a connector housing. The cover body includes a ferrous base metal body, and a Zn-based plating layer formed on a surface of the base metal body. The cover body has a through hole formed through the base metal body and the plating layer. The terminal is passed through the through hole and electrically connected to an electric circuit. The connector housing is formed on the cover body so as to surround the terminal. A laser mark is formed on the cover body. The laser mark has a circular shape about the through hole and penetrates the plating layer to the base metal body. The connector housing extends to the base metal body through the plating layer within the laser mark.

Abstract: A motor-driven compressor includes collars, which maintain the gap between a cover and an outer surface of a first housing member. Fasteners fasten the cover to the first housing member. Each collar is arranged to face a seating surface of the head of the corresponding fastener such that the cover is sandwiched between the collars and the seating surfaces. Each collar thus includes a facing portion, which faces the seating surface and receives a pressing force from the seating surface via the cover, and a transmitting portion, which transmits the pressing force received at the facing portion to a base member. Accordingly, the pressing force applied through the seating surface of the fastener is transmitted to the base member through the collar, so that the base member is pressed against the outer surface of the first housing member.

Abstract: A motor-driven compressor includes a connector receiving portion provided on the outer surface of a housing. A wiring connection portion is provided in the connector receiving portion and supplies electricity from an external power source to a motor drive circuit. An insulating member provided inside the connector receiving portion insulates the wiring connection portion and the connector receiving portion from each other. An electrical wire is arranged between the inner surface of the connector receiving portion and the insulating member. The electric wire is used for a purpose other than supply of electricity to the motor drive circuit. A recess is formed in at least one of the inner surface of the connector receiving portion and the outer surface of the insulating member. The recess forms a wiring space, in which the electrical wire is arranged, between the connector receiving portion and the insulating member.

Abstract: An electric compressor includes a motor housing, an inverter, a cover, and a fastener. The inverter includes a board; an electronic component; a holder composed of an insulating material, the holder containing the electronic component and supporting the board; a bus bar integrated with the holder, and electrically connected to a circuit pattern and the motor housing; and a tubular member interposed between the cover and the bus bar, with the fastener inserted in the tubular member. The fastening force from the fastener causes the tubular member to press the bus bar toward the motor housing.
