Abstract: 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.

Abstract: 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.

Abstract: A hermetic terminal is disclosed as having a body including an exterior surface and a plurality of openings in the body accommodating a pin extending through each opening that is hermetically sealed and electrically isolated from the body. The terminal also includes a dielectric pin-isolating feature forming a barrier that increases the operative through-air spacing between the pins of the terminal. The power rating for the terminal is thereby increased without increasing the overall size of the terminal.

Abstract: An external connector block that can be positioned over multiple standard-sized power supply terminals that are secured to the housing of, e.g., a compressor is disclosed. The connector block includes an electrically conductive bridge connecting respective pins of the terminals in parallel. By connecting the terminals in parallel, the connector block increases the maximum allowable operating current of a terminal connection, while still utilizing standard-sized power terminal feed-throughs. As such, the connector block of the present disclosure may enable higher power rated applications without requiring a new power supply terminal design.

Abstract: 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.
