Patent ID: 6910904

Claim:
A hermetically sealed compressor assembly comprising: a hermetically sealed housing; an electric motor disposed in said housing; a compression mechanism disposed in said housing and operatively coupled to said motor; a terminal assembly comprising a cup-shaped terminal body extending through and sealingly attached to said housing, said terminal assembly having electrically conductive pins extending through and insulated from said terminal body; a cluster block assembly disposed within said housing and connected to said terminal assembly, said pins electrically connected to said motor through said cluster block assembly, said cluster block assembly including a cluster block which is fitted to said terminal body, said cluster block defining a free volume therein; a cavity being defined between the interior of the cup-shaped terminal body and an interfacing surface of said cluster block; and a substantially solid dielectric material substantially filling at least one of said cavity and substantially all said free volume within said cluster block assembly, wherein said cluster block assembly includes a means of ingress for said dielectric material to enter at least one of said cavity and said free volume when said cluster block is fitted to said terminal body.
