Motor-driven compressor and method for manufacturing the same

摘要

A motor-driven compressor includes an electric motor having a stator core, a compression mechanism driven by the electric motor, a motor housing accommodating the electric motor, and a cluster block engaged with the stator core in the motor housing. The stator core of the electric motor and the motor housing are assembled by shrink fit. The cluster block accommodates a connecting terminal for electrical connection between a conductor connected to a motor drive circuit and a lead wire drawn from the electric motor. The cluster block has a terminal hole for receiving the connecting terminal and has an opening that is provided separately from the terminal hole.

1. A motor-driven compressor, comprising:
an electric motor having a stator core; a compression mechanism driven by the electric motor; a motor housing accommodating the electric motor, wherein the stator core of the electric motor and the motor housing are assembled by shrink fit; and a cluster block engaged with the stator core in the motor housing, the cluster block accommodating a connecting terminal for electrical connection between a conductor connected to a motor drive circuit and a lead wire drawn from the electric motor, wherein the cluster block has a terminal hole for receiving the connecting terminal and has an opening that is provided separately from the terminal hole, wherein the terminal hole is of a rectangular cross section having opposite long sides, wherein the terminal hole is oriented so that the long side is inclined, relative to an upper surface of the cluster block, and wherein the opening is formed at a position between the long side of the terminal hole and an opposing corner of the cluster block.
