Estimating the term…
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. An electricity conduction wire at an end of a lead wire for supplying electricity to the electric motor is directly connected to the end of the terminal member which is on the electric motor-storing section side. An insulation cover is provided so as to extend from the electric motor-storing 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 can exhibit high insulation performance even if polyalkylene glycol-based oil is used as lubricating oil-containing 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.
A terminal device for an electric compressor having a partition wall which is located between a storing section for an electric motor for driving a compression mechanism, in which lubricating oil-containing fluid to be compressed is present, and a circuit section for supplying electricity to said electric motor, for isolating said both sections from each other, and a terminal member for supplying electricity to said electric motor which extends through said partition wall in a sealed and insulated manner, characterized in that an electricity conduction wire at an end of a lead wire for supplying electricity to said electric motor is directly connected to an end of said terminal member which is on an electric motor-storing section side, and an insulation cover is provided so as to extend from said electric motor-storing section-side end of said terminal member to an insulation cover tube of said electricity conduction wire of said lead wire for supplying electricity to said electric motor.
