Motor-driven compressor

Abstract

A motor-driven compressor includes a connector-receiving portion provided on the outer surface of a housing. A wiring connection portion is provided in the connector-receiving portion and supplies electricity from an external power source to a motor drive circuit. The wiring connection portion includes a first terminal, a second terminal, and a metal plate for connecting the first and the second terminals to each other. The first and the second terminals have a first end-connection portion and a second end-connection portion, respectively. The second end-connection portion of the first terminal is electrically connected to the external power source, and the second end-connection portion of the second terminal is electrically connected to the motor drive circuit. The metal plate has opposite ends, which are connected to the first end-connection portion of the first terminal and the first end-connection portion of the second terminal, respectively.

1 . A motor-driven compressor, comprising:
 a housing;   a compression portion, an electric motor, and a motor drive circuit, which are accommodated in the housing;   a connector-receiving portion provided on an outer surface of the housing; and   a wiring connection portion provided in the connector-receiving portion, the wiring connection portion being adapted for supplying electricity from an external power source to the motor drive circuit,   wherein the wiring connection portion includes
 a first terminal having a first end-connection portion at an end thereof and a second end-connection portion at another end thereof, the second end-connection portion being electrically connected to the external power source, 
 a second terminal having a first end-connection portion at an end thereof and a second end-connection portion at another end thereof, the second end-connection portion being electrically connected to the motor drive circuit, and 
 a metal plate having opposite ends, which are connected to the first end-connection portion of the first terminal and the first end-connection portion of the second terminal, respectively, to connect the first terminal and the second terminal to each other. 
   
     
     
         2 . The motor-driven compressor according to  claim 1 , wherein
 an end of the metal plate and the first end-connection portion of the first terminal are welded to each other, and   another end of the metal plate and the first end-connection portion of the second terminal are welded to each other.   
     
     
         3 . The motor-driven compressor according to  claim 1 , wherein
 the connector-receiving portion is made of metal, and   an insulating member is located between the wiring connection portion and the connector-receiving portion.   
     
     
         4 . The motor-driven compressor according to  claim 1 , wherein the housing accommodates a rotary shaft having an axial direction, and wherein the connector-receiving portion extends in the axial direction of the rotary shaft and toward the electric motor. 
     
     
         5 . The motor-driven compressor according to  claim 4 , wherein the compression portion, the electric motor, and the motor drive circuit are accommodated in the housing to be arranged in that order in the axial direction of the rotary shaft.
