TERMINAL DEVICE FOR ELECTRIC COMPRESSOR

摘要

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-receiving section, which receives the electric motor and also receives lubricating oil-containing fluid to be compressed, and a circuit for supplying electricity to the electric motor. The terminal member extends to penetrate through the partition wall in a sealed and insulated manner. An electricity conduction wire at an end of a lead wire for supplying electricity to the electric motor is directly connected to that end of the terminal member which is on the electric motor-receiving section side. An insulation cover is placed so as to extend from the electric motor-receiving section-side end of the terminal member to an insulation cover tube of the electricity conduction wire of the lead wire for supplying electricity to the electric motor. The terminal device has sufficiently 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, has high insulation performance, and is constructed at low cost.
