Abstract

A vacuum pump ( 10 ) has a vacuum-tight housing ( 12 ) and having a gas-tight electrical leadthrough assembly ( 20 ) for producing an electrical connection between an electrical component ( 14,16,18 ) within the housing ( 12 ) and the exterior of the housing. The leadthrough assembly ( 20 ) is formed by a housing opening ( 22 ), by a sealing compound body ( 24 ) seated on the opening, by an electric line in the sealing compound body ( 24 ), by a sealing ring ( 26 ) between the opening edge of the housing opening ( 22 ) and the sealing compound body ( 24 ), and by a fixing means ( 32 ) for fastening the sealing compound body ( 24 ) to the housing ( 12 ).

Claims

exact text as granted — not AI-modified
1 . A vacuum pump comprising
 a vacuum-tight housing,   an elastic component arranged within said housing,   a gas-tight electrical leadthrough assembly for producing an electrical connection between an electrical component within the housing and the exterior of the housing,   wherein said leadthrough assembly is formed by   a housing opening,   a sealing compound body positioned on said housing opening and enclosing an electric line extending between the interior of the housing and the exterior of the housing,   a sealing ring between an opening edge of the housing opening and the sealing compound body, and   a fixing means for attachment of the sealing compound body to the housing.   
   
   
       2 . The vacuum pump according to  claim 1 , wherein said sealing compound body is mounted to said housing opening from the outside. 
   
   
       3 . The vacuum pump according to  claim 1 , wherein said fixing means is a sealing-compound housing. 
   
   
       4 . The vacuum pump according to  claim 1 , wherein said electric line comprises a circuit board arranged within the sealing compound body. 
   
   
       5 . The vacuum pump according to  claim 1 , wherein said electric line comprises respectively one electric plug towards the interior and towards the exterior. 
   
   
       6 . The vacuum pump according to  claim 4 , wherein said circuit board comprises electronic components. 
   
   
       7 . The vacuum pump according to  claim 6 , wherein one of said electronic components is configured as a readable pump-data memory. 
   
   
       8 . The vacuum pump according to  claim 1 , wherein the material of the sealing compound body is an epoxy resin.
