Electric compressor
An electric compressor which compresses a coolant by driving a compression mechanism with a motor which is drive controlled by a drive circuit, said compressor being characterized by having a lead pin connected to a current output section of the drive circuit, and a connector which, by being mounted on the lead pin, can provide electrical continuity between the current output section of the drive circuit and a current input section of the motor, said connector being provided with a connector terminal which contacts the lead pin at the time of mounting on the lead pin, a connector housing which houses the connector terminal, a vacuum flow path that communicates the inside of the connector housing with the outside thereof, and a sealing member which provides a seal between the connector housing and the vacuum flow path. Thus, provided is a compressor which is easy to produce and for which it is possible to secure the electrical insulation properties of the interior of the compressor while homogenizing the internal pressure thereof.
1. An electric compressor which compresses a refrigerant by driving a compression mechanism with a motor which is controlled to drive with a drive circuit, a lead pin connected to an electric current output section of the drive circuit, and a connector attached to the lead pin to electrically connect the electric current output section with an electric current input section of the motor, wherein the connector comprises a connector terminal which contacts the lead pin to attach the connector to the lead pin, a connector housing which houses the connector terminal, a vacuum flow path which communicates an inside with an outside of the connector housing, and a sealing member which provides a seal between the connector housing and the vacuum flow path.
2. The electric compressor according to claim 1 , wherein an electric insulator is interposed between the connector housing and the lead pin.
3. The electric compressor according to claim 1 , wherein the sealing member is made of an electric insulator.
4. The electric compressor according to claim 1 , wherein the vacuum flow path is formed with a gap of a conducting wire bundle which electrically communicates the connector terminal with an electric current input section of the motor.
5. The electric compressor according to claim 1 , wherein the connector housing is a cluster housing which houses a plurality of connector terminals.
6. The electric compressor according to claim 1 , wherein the electric compressor having an interior that is lubricated with a polyalkylene-based lubricating oil.
