Electric compressor

摘要

An electric compressor including a compression mechanism, an electric motor, an inverter, a compressor housing, a sealed terminal, a cluster block, and a metal brace. The sealed terminal is arranged in the compressor housing and electrically connects the inverter and the electric motor. Further, the sealed terminal includes a terminal pin, which is formed from a conductive material, a terminal holder, and an insulative body. The cluster block includes an insertion hole into which the terminal pin is inserted. The metal brace electrically connects the terminal pin to the lead wire. The cluster block includes a protrusion projecting around the insertion hole and surrounding part of the insulative body. The insertion hole has an inside diameter larger than an outside diameter of the terminal pin.

1. An electric compressor comprising:
a compression mechanism; an electric motor that drives the compression mechanism, wherein the electric motor is connected to a lead wire; an inverter that drives the electric motor; a compressor housing that accommodates the electric motor and the compression mechanism; a sealed terminal arranged in the compressor housing and electrically connecting the inverter and the electric motor, wherein the sealed terminal includes a terminal pin, which is formed from a conductive material, a terminal holder, which holds the terminal pin, and an insulative body, which insulates the terminal pin from the terminal holder; a cluster block arranged inside the compressor housing and including an insertion hole into which the terminal pin is inserted; and a metal brace arranged inside the cluster block and electrically connecting the terminal pin to the lead wire, wherein the cluster block includes a protrusion projecting around the insertion hole and surrounding part of the insulative body to form a gap between an inner surface of the protrusion and the insulative body, and the insertion hole has an inside diameter larger than an outside diameter of the terminal pin.
