Abstract: In combination with at least two terminal assemblies each having body members sealed in the housing wall of a hermetically sealed compressor with outer pin segments extending therefrom, two terminal blocks engageably connected to each of the body members to electrically engage the outer pin segments of the terminal assemblies and a power lead block arrangement interconnectable with one of the terminal blocks to electrically connect the two terminal blocks to a power source.

Abstract: A heating apparatus for heating a fluid medium confined in a hermetically sealed housing chamber including a terminal assembly having a body member sealed in the housing chamber wall with pins extending in sealed relation therethrough to provide electrically conductive inner and outer pin segments respectively connected to heat transfer members and an electric power source, the heat transfer members including a heating element and a support for the heating element which is independent of a novel electrical connection between the inner pin segment and heating element to insure stable electrical connection and a minimum of vibration.

Abstract: A heating apparatus for heating a fluid medium confined in a hermetically sealed housing chamber including a terminal assembly having a body member sealed in the housing chamber wall with pin means extending in sealed relation therethrough to provide electrically conductive inner and outer pin segments respectively connected to a heat transfer member and an electric power source, the inner pin segment means and heating element being electrically insulated from the housing wall.

Abstract: A current resistive terminal block for connection to outer pin segment means projecting outwardly from a body member of a hermetic terminal assembly sealed in a housing wall, the terminal block including a main channel means to protect the outer pin segment means and diffuse possible leakage from the terminal assembly and subchannel means to encase and secure fused lead end wire connection means for the outer pin segment means.

Abstract: A hermetic terminal assembly for a housing including a fuse-like area positioned in the outer pin segment of a terminal pin extending in sealed relation through the body member of the terminal assembly which body member can be sealed to a housing wall, the fuse-like area in the outer pin segment being covered with a thermally decomposable coating which in the event of decomposition includes an arc suppressant. A pin guard and lead wire end connection securing device is provided to protect the outer pin segment and to secure the lead wire end connection thereto.
