A fluid machine includes an inverter compartment defined by a housing and a cover, the inverter compartment accommodating an inverter, and a wire electrically connected to an external connector and supplying power to a circuit board of the inverter. The wire includes a board coupling portion electrically connected to the circuit board, a connector coupling portion electrically connected to the external connector, and an extended portion extending along a wall surface of the cover and connecting the board coupling portion and the connector coupling portion. The fluid machine further includes a plastic mold covering the extended portion, and an anchor formed integrally with the plastic mold and engaged with a through-hole of the cover. The extended portion is held on the wall surface of the cover by the anchor.

Fluid machine

A motor-driven compressor includes a compression portion, an electric motor, an inverter, and a metal housing. The inverter includes three-phase switching elements and a plastic holder that retains the three-phase switching elements. The housing includes a thermal radiation surface. The holder includes a metal spring. The holder is fixed to the housing using two fasteners. The three-phase switching elements are laid out between the two fasteners. The switching elements at opposite ends of the three-phase switching elements are pressed toward the thermal radiation surface by only the holder. The switching element at the middle of the three-phase switching elements is pressed toward the thermal radiation surface by the holder and the spring.

Motor-driven compressor

A motor-driven compressor includes a compression unit, an electric motor, a motor controller, a housing, and a connector. The motor controller includes a circuit board. The housing includes an inverter accommodation chamber, and the inverter accommodation chamber accommodates the motor controller. The connector is accommodated in the inverter accommodation chamber and electrically connects the circuit board and a member located outside the inverter accommodation chamber. The connector includes one or more busbars and a case. The one or more busbars are electrically connected to the circuit board. The case is formed from a resin and accommodates the one or more busbars. The circuit board and the connector are fastened to the housing. The one or more busbars are allowed to move in the case when the circuit board vibrates.
