Abstract

PURPOSE:To remarkably reduce the size of a compressor body by improving a power source terminal to supply power externally to a motor section. CONSTITUTION:A closed compressor 1 has a power source terminal 6 for supplying power externally to its motor section 3, the side wall of a sealed case 2 secured at the core 8 of a stator 7 of the motor section 3, and a notch 14 as a recess 11 for containing the terminal 6 projected inward of the case 2 in the core 8. Thus, the distance berween the coil terminal 20 of the stator 7 and the terminal 6 is approached, and the length of the lead 21 for connecting the terminal 20 to the terminal 6 is remarkably shortened. Accordingly, it is not necessary to draw the lead 21 in the case 2, a space for drawing the lead 21 becomes unnecessary between the case 2 and the motor section 3 to remarkably reduce the size of the body of the compressor 1.

The power supply terminal part (i) is provided with a storage recess 11 and a cutout part 1/1 (C) which protrudes into the inner hole of the fixed stator. The power supply terminal part 6 is brought close to the iTl J, and the length of the first output line 21 connecting the power supply terminal part 20 and the power supply terminal part 6 is made as short as possible. Therefore, there is no need to route the C1 exit wire 21 inside the closed sheath 2, and the closed case 2
There is no need for a space for routing the outlet wire 21 between the do-[-9 section 3, and the size of the main body of the IJE compressor 1 can be reduced in size. .

In addition, the power supply terminal section 6 is connected to a power supply connection terminal 15 connected to the external power supply side and a connection terminal 1 connected to the seventh terminal section 3 side (a power supply connection terminal 15 that is divided into two parts and fixed to the sealed case 2).
