Abstract:
1. A method of making a hermetically-sealed electrical feed-through device, comprising the steps of: inserting an elongate conductor made of solid aluminum, copper, molybdenum or titanium within a hollow portion of a hard plastic insulator body and the plastic insulator body within a hollow outer jacket made of stainless steel to form an assembly; before said inserting step, pre-forming the hard plastic insulator body with a spaced-apart pair of annular circumferentially-extending grooves on its inner surface for facing the conductor within the assembly and three spaced-apart circumferentially-extending grooves on its outer surface for facing the outer jacket within the assembly; and after said inserting step, crimping and/or swage-crimping the assembly at ambient temperature to cause the materials of the conductor and outer jacket to be displaced and extruded into the pre-formed annular circumferentially-extending grooves of the plastic insulator body thereby creating annular circumferentially-extending mechanical interlocks between the conductor, insulator body, and outer jacket.
