Compressor

Abstract

A compressor includes a housing member having a through hole. The compressor includes a conductive portion through which external electricity is supplied to a motor mechanism. The conductive portion has a lead extending from the motor mechanism, and a connector terminal. The connector terminal is connected to the lead to permit the external electricity to be conducted to the lead. The connector terminal is attached to the through hole such that a joint between the lead and the connector terminal is located in the through hole to face inward of the housing member. A viscoelastic insulating material fills the through hole. Therefore, the compressor ensures reliable insulation of the terminal from a housing member.

       3 . The compressor according to  claim 1 , wherein the connector terminal is fixed to the housing member to block the through hole from the outside of the housing member.  
   
   
       4 . The compressor according to  claim 1 , further comprising a sealing member located between the connector terminal and the housing member.  
   
   
       5 . The compressor according to  claim 1 , wherein the joint is buried in the viscoelastic insulating material.  
   
   
       6 . The compressor according to  claim 1 , wherein the viscoelastic insulating material is an elastic silicone resin.  
   
   
       7 . The compressor according to  claim 1 , wherein the viscoelastic insulating material fills an inward portion of the through hole in the housing member, and wherein a dissimilar insulating material that is different from the viscoelastic insulating material fills a space between the connector terminal and the viscoelastic insulating material in the through hole.  
   
   
       8 . The compressor according to  claim 7 , wherein the joint is buried in the dissimilar insulating material.  
   
   
       9 . The compressor according to  claim 7 , wherein the dissimilar insulating material is a cured resin.  
   
   
       10 . The compressor according to  claim 1 , wherein the connector terminal is a hermetic terminal.  
   
   
       11 . The compressor according to  claim 1 , wherein the connector terminal has a cap body that blocks an outer opening of the through hole at the outer surface of the housing member, and wherein the joint is located between the cap body and an inner opening of the through hole in the housing member.  
   
   
       12 . The compressor according to  claim 11 , wherein the diameter of the outer opening of the through hole is greater than the diameter of the remainder of the through hole, and wherein the cap body is accommodated in the outer opening of the through hole.  
   
   
       13 . The compressor according to  claim 11 , further comprising a sealing member located between the cap body and a circumferential surface of the through hole.  
   
   
       14 . The compressor according to  claim 11 , wherein the viscoelastic insulating material blocks the inner opening of the through hole, and wherein a dissimilar insulating material that is different from the viscoelastic insulating material fills a space between the cap body and the viscoelastic insulating material in the through hole.  
   
   
       15 . The compressor according to  claim 1 , wherein the housing member has at least one of an inner boss projecting inward from an area around an inner opening of the through hole and an outer boss projecting outward from an area around an outer opening of the through hole.  
   
   
       16 . A compressor, comprising: 
 a housing member forming a shell of the compressor, the housing member having a through hole;    a compression mechanism for compressing drawn gas;    a motor mechanism for driving the compression mechanism;    a conductive portion through which external electricity is supplied to the motor mechanism, the conductive portion having a lead extending from the motor mechanism, and a connector terminal, the connector terminal being connected to the lead to permit the external electricity to be conducted to the lead, wherein the connector terminal has a cap body that blocks an outer opening of the through hole at the outer surface of the housing member, and a pin that extends through the cap body and is connected to the lead, and wherein the joint is located between the cap body and an inner opening of the through hole in the housing member; and    a viscoelastic insulating material filling the through hole.
