Hermetically-sealed feed-through device

摘要

A hermetically-sealed electrical feed-through device includes a conductor, an insulating sleeve, and an outer ferule interconnected in a manner preventing relative rotation therebetween and/or includes a thermocouple in direct contact with the conductor for monitoring temperature. The conductor can have a body section extending along an axis and having an outer contour including flats or an outwardly-extending eccentrically-shaped lobe. The sleeve confronts and covers the body section of the conductor and accommodates and engages the outer contour at the flats or lobe to prevent rotation of the conductor relative to the sleeve, and the outer ferrule sandwiches the insulating sleeve between the outer ferrule and the outer contour of the conductor. The outer ferrule accommodates and engages the sleeve adjacent the outer contour of the conductor at the flats or lobe to prevent rotation of the insulator sleeve relative to the outer ferrule.

主权项

1. A hermetically-sealed electrical feed-through device, comprising:
a center conductor having a body section and opposite exposed ends extending along a longitudinally-extending axis of said conductor, said body section having an outer contour including flats or an outwardly-extending eccentrically-shaped lobe; an electrically-insulating sleeve confronting and covering said body section of said conductor and accommodating and engaging said outer contour at said flats or lobe to prevent rotation of said conductor about said longitudinally-extending axis relative to said insulating sleeve; an outer ferrule confronting and covering said insulating sleeve to sandwich said insulating sleeve between said outer ferrule and said outer contour of said conductor, said outer ferrule accommodating and engaging said insulating sleeve adjacent said outer contour of said body section of said conductor at said flats or lobe to prevent rotation of said insulator sleeve about said longitudinally-extending axis relative to said outer ferrule; and a thermocouple embedded within said center conductor.
