Terminal device for electric compressor

Abstract

A terminal device for an electric compressor has a partition wall and a terminal member for supplying electricity to an electric motor for driving a compression mechanism. The partition wall is located between an electric motor-storing section, which stores the electric motor and in which lubricating oil-containing fluid to be compressed is present, and a circuit section for supplying electricity to the electric motor. The terminal member extends through the partition wall in a sealed and insulated manner. The terminal member is constructed as a steel bolt-like member, and an end of a lead wire for supplying electricity to the electric motor is directly connected by caulking to the end of the terminal member at the electric motor-storing section side. The terminal device can exhibit high insulation performance even if polyalkylene glycol-based oil is used as lubricating oil contained in fluid to be compressed. Further, the terminal device has a simple structure not requiring a cluster, can ensure high insulation performance, and can be constructed at low cost.
