Electric compressor

Abstract

An electric compressor ( 1 ) includes an electric motor ( 2 ), a drive circuit (inverter ( 3 )) that drives the electric motor ( 2 ), a compression mechanism ( 4 ) driven by the electric motor ( 2 ) to compress a refrigerant, a conductive member (lead pin ( 15 )) connected to the drive circuit (inverter ( 3 )), a conducting wire ( 7 ) drawn from the electric motor ( 2 ), a connector terminal ( 11 ) that connects the conducting wire ( 7 ) and the conductive member (lead pin ( 15 )), a connector housing ( 12 ) that includes an opening ( 13 ) through which the conducting wire ( 7 ) is passed and that houses the connector terminal ( 11 ), a seal member ( 20 ) interposed between an inner wall of the opening ( 13 ) and the conducting wire ( 7 ), and a press member ( 30 ) that presses the seal member ( 20 ) toward the conducting wire ( 7 ).

1 . An electric compressor comprising:
 an electric motor;   a drive circuit that drives the electric motor;   a compression mechanism driven by the electric motor to compress a refrigerant;   a conductive member connected to the drive circuit;   a conducting wire drawn from the electric motor;   a connector terminal that connects the conducting wire and the conductive member;   a connector housing that has an opening through which the conducting wire is passed and that houses the connector terminal;   a seal member interposed between an inner wall of the opening and the conducting wire; and   a press member that presses the seal member toward the conducting wire.   
     
     
         2 . The electric compressor according to  claim 1 ,
 wherein the seal member comprises:
 a main body portion that has a through-hole through which the conducting wire is passed and that is fitted to the inner wall of the opening; and 
 a tubular portion that extends from the main body portion outwardly of the connector housing and that has an internal space that communicates with the through-hole of the main body portion and through which the conducting wire is passed, and 
   wherein the press member presses the tubular portion toward the conducting wire.   
     
     
         3 . The electric compressor according to  claim 2 , wherein the press member comprises a pair of clamp members that sandwich an outer peripheral portion of the tubular portion. 
     
     
         4 . The electric compressor according to  claim 1 , wherein the press member comprises an engaging portion that engages with the connector housing. 
     
     
         5 . The electric compressor according to  claim 1 , wherein the seal member is formed of an insulating rubber material. 
     
     
         6 . The electric compressor according to  claim 1 ,
 wherein a conducting wire bundle composed of a plurality of the conducting wires passes through the opening, and   wherein the seal member is interposed between the inner wall of the opening and the conducting wire bundle.   
     
     
         7 . The electric compressor according to  claim 1 , wherein the connector housing houses a plurality of the connector terminals.
