A ceramic seal assembly for electrically insulating and hermetically securing a terminal to a housing through which the terminal extends. The housing contains a fluid at a high pressure and an electrical device to which the terminal is connected. An adapter is provided for hermetically securing the seal assembly to the housing. The adapter comprises a generally tubular member defining two end portions and a collar secured to one of the two end portions. The seal assembly and housing are hermetically secured to the tubular member at separate locations. The seal assembly contains at least one annular ceramic member and is oriented such that the high pressure fluid contained within the housing causes the annular ceramic member to be in compression and thereby maintain a seal between the terminal and the housing.

In an assembly for sealing a terminal extending through a housing containing a fluid and an electrical device to which the terminal is connected, the assembly having a substantially cylindrical tube hermetically secured to the terminal, a collar secured to the housing, a first substantially annular ceramic member positioned around the tube and hermetically secured to the tube and the collar, and a second substantially annular ceramic member positioned around the tube and hermetically secured to the collar, the improvement comprising: means for restraining said first and said second substantially annular ceramic members against axial movement outwardly from said housing; and an orientation of said first and said second substantially annular ceramic members within said housing such that forces exerted upon said first and said second substantially annular ceramic members by increasing fluid pressure within said housing causes said first and said second substantially annular ceramic members in cooperation with said restraining means to be in compression and thereby maintain a seal between said terminal and said housing.
