Abstract
A hermetically sealed compressor assembly including a housing, an electric motor located in the housing, a compression mechanism located in the housing and operatively coupled to the motor, and a terminal assembly comprising a cup-shaped terminal body and having electrically conductive pins extending therethrough. The cup-shaped terminal body extends through and is sealingly attached to the housing. A cluster block assembly is in communication with the terminal assembly and includes a cluster block fitted to the terminal body, the cluster block having free volume therein. The pins are electrically connected to the motor through the cluster block assembly. A cavity is defined between the interior of the cup-shaped terminal body and the cluster block, and a dielectric material substantially fills at least one of the cavity and the cluster block free volume. The cluster block assembly may also include one or more apertures to provide for the introduction of the dielectric material which may be introduced after the mating of the connectors.
