A hermetic terminal assembly wherein a radially extending flange on a current conducting pin that extends through a hole defined by a cover member adapted to be secured to an opening in a motor housing is surrounded by an electrically insulating sleeve with the inner axial extremity of the sleeve extending at an axial location relative the pin substantially beyond the inner face of the radially extending flange to provide an extended tortuous path between the flange on the pin and the cover member, the pin having a reduced neck portion on the inner end thereof adjacent the inner face of the flange to provide a fuse-like area.

A hermetic terminal assembly adapted to be hermetically secured to an opening in a motor unit housing comprising: a cover member having at least one hole therein; a current conducting pin extending through said hole, said pin having an outer end to extend externally of said housing to receive an electrical connection to a current source and an inner end to extend within said housing to receive an electrical connection to a motor disposed in said housing, said inner end of said pin having a flange extending generally radially therefrom, said flange having an inner face facing said inner end of said pin and an opposite face facing said outer end of said pin; a seal bonding said pin to the inside surface defining said cover member hole; and a hollow electrically insulating sleeve surrounding said pin and said flange extending therefrom with the inner axial extremity of said sleeve extending at an axial location relative said pin substantially beyond the axial location of the inner face of said flange and the opposite axial extremity of said sleeve being bonded to said seal to provide an extended tortuous path between said flange on said pin and said cover member to minimize the possibilities of electrical arcing therebetween, the opposite face of said flange being axially spaced from the inner wall of said opposite extremity of said sleeve to accommodate for different coefficients of expansion of differing materials.
