<P>PROBLEM TO BE SOLVED: To provide an electric compressor which can prevent adhesion of abrasion powder of a metallic material to an airtight terminal without increasing the size of the electric compressor. <P>SOLUTION: A terminal pin 24 is formed of a conductive material, and is held by a terminal holder 23 via a first ceramic insulator 26 disposed on a side of an inverter storage camber 18 and a second glass insulator 27 disposed on an inner 2A side of a housing 2. Since wall thickness X1 of the ceramics can be set freely, axial length Y1 of the terminal pin 24 is shortened to reduce height of the first insulator 26. Since the glass is welded, wall thickness X2 cannot be increased, and thus, by increasing axial length Y2 of the terminal pin 24, an insulation distance is secured. Therefore, the second glass insulator 27 can prevent adhesion of abrasion powder, and thereby, short circuit caused by abrasion powder is prevented, so as to prevent decline in operating efficiency of an electric compressor. The first insulator 26 can be set short, so as to prevent increase in the size of the electric compressor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
