A glass-to-metal hermetic seal assembly in a sight glass assembly or a hermetic terminal assembly is disclosed and includes a glass component, an intermediate component, and an outer ring. The intermediate component is provided around the glass component. The glass component is fused to the intermediate component. The outer ring, which has a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of the glass component, compresses the intermediate component against the glass component to create a hermetic compression seal.

Hermetic glass-to-metal seal assembly and method of manufacturing hermetic glass-to-metal seal assembly

A hermetic terminal assembly includes a terminal body and terminal pins extending through the terminal body. The terminal pins each have a first end configured for connection to a power source disposed outside of a hermetic compressor and a second end configured for direct connection to motor windings disposed within hermetic compressor.

Hermetically sealed terminal pins with holes for connecting to wires

A power terminal feed-through incorporates a metallic body through which extend one or more current conducting pins that are hermetically sealed to the metallic body by a glass-to-metal seal. The metallic body includes an annular lip with a protrusion. During welding installation of the power terminal feed-through, the protrusion serves to assist in the welding process, better controlling the location and definition of the weld between the metallic body and a housing, and to focus the welding heat at the protrusion, thereby protecting the glass-to-metal seal. The glass-to-metal seal can be a single glass insert through which the current conducting pins extend, thereby reducing the pin circle diameter and the overall size of the power terminal feed-through.
