Abstract
A motor-driven compressor is provided with a power supply terminal secured to a metallic housing and electrically connected to a power source. The power supply terminal includes a base secured to the metallic housing, a conductive element secured to the base, and an insulator for insulating the conductive element from the base. A portion of the conductive element and a portion of the insulator that are located inside the metallic housing are covered with an insulating resinous cover.
Claims10
A power supply terminal for use with a motor-driven compressor having a metallic housing in which a compression mechanism and an electric motor for driving the compression mechanism are accommodated, said power supply terminal comprising:
- a base to be secured to the metallic housing;
- a conductive element secured to said base;
- a conductive element connector secured to said conductive element for connection with the electric motor;
- an insulator for insulating said conductive element from said base;
- and
- an insulating resinous cover for covering said conductive element connector, a portion of said conductive element and a portion of said insulator that are arranged to be located inside the metallic housing.
A method of insulating a power supply terminal from a metallic housing of a motor-driven compressor, said power supply terminal comprising a base to be secured to the metallic housing, a conductive element secured to the base, and an insulator for insulating the conductive element from the base, said method comprising:
- (a) moving a heat-shrinkable resinous tube towards the power supply terminal so that a portion of the conductive element and a portion of the insulator that are located inside the metallic housing are covered with the heat-shrinkable resinous tube;
- (b) inserting a conductive element connector into an opening of the heat-shrinkable resinous tube and connecting the conductive element connector to the conductive element;
- and
- (c) heating the heat-shrinkable resinous tube to shrink the heat-shrinkable resinous tube.
