Compressor and refrigeration apparatus

Abstract

A compressor and a refrigeration apparatus are provided. The housing of the compressor has a first terminal and a second terminal. The motor of the compressor has a stator, a first line group and a second line group. The first line group extends from a first position of an end face of the stator and is connected to the first terminal. The second line group extends from a second position of the end face and is connected to the second terminal. A midpoint between the first position and the second position defines a middle point. A plane passing through the middle point and an axis of an output shaft of the motor is defined as a middle plane. The first terminal and the first position are at one side of the middle plane. The second terminal and the second position are at the other side of the middle plane.

 the first line group extends from a first position of an end face of the stator and is connected to the first connecting terminal, and the second line group extends from a second position of the end face of the stator and is connected to the second connecting terminal; 
   wherein a midpoint between the first position and the second position is defined as a middle point, a plane passing through the middle point and an axis of an output shaft of the motor is defined as a middle plane, the first connecting terminal and the first position are positioned at one side of the middle plane, and the second connecting terminal and the second position are positioned at the other side of the middle plane.   
     
     
         2 . The compressor according to  claim 1 , wherein:
 the first connecting terminal comprises a plurality of first connecting posts, and the plurality of first extension lines are respectively connected to the plurality of first connecting posts; and   the second connecting terminal comprises a plurality of second connecting posts, and the plurality of second extension lines are respectively connected to the plurality of second connecting posts.   
     
     
         3 . The compressor according to  claim 2 , wherein:
 the plurality of first extension lines comprise three first extension lines, and the plurality of second extension lines comprise three second extension lines; and   the plurality of first connecting posts comprise three first connecting posts, and the plurality of second connecting posts comprise three second connecting posts.   
     
     
         4 . The compressor according to  claim 3 , wherein:
 the three first connecting posts are parallel to each other and the distances between every two of the three first connecting posts are equal to each other; and   the three second connecting posts are parallel to each other and the distances between every two of the three second connecting posts are equal to each other.   
     
     
         5 . The compressor according to  claim 1 , wherein the number of the plurality of first extension lines is equal to the number of the plurality of second extension lines. 
     
     
         6 . The compressor according to  claim 2 , further comprising:
 a first socket, wherein the first line group is connected to the first socket, and the first socket is plugged on the plurality of first connecting posts; and   a second socket, wherein the second line group is connected to the second socket, and the second socket is plugged on the plurality of second connecting posts.   
     
     
         7 . The compressor according to  claim 1 , wherein the motor comprises a permanent magnet motor. 
     
     
         8 . The compressor according to  claim 1 , wherein:
 the motor further comprises a rotor disposed in the stator; and   the rotor comprises a permanent magnet, wherein the permanent magnet comprises a rare earth permanent magnet or a ferrite permanent magnet, and the permanent magnet comprises a plate-shaped permanent magnet or a tile-shaped permanent magnet.   
     
     
         9 . A refrigeration apparatus comprising:
 the compressor according to  claim 1 .
