ABSTRACT:
A terminal assembly includes a ferrule and a terminal pin disposed in spaced relationship to the ferrule. First layers made from a first ceramic insulating material are disposed in spaced relationship to each other in the space between the terminal pin and the ferrule. The layers are primarily polycrystalline but partially amorphous. Second layers made from a second ceramic insulating material are disposed in spaced relationship to each other in the space between the terminal pin and the ferrule and between the first layers. The second layers are fused to the terminal pin and the ferrule and the first layers. The second layers are primarily amorphous but partially polycrystalline. Layers of a third insulating material having relatively high characteristics of electrical insulation and having a lower melting temperature than the first and second layers may be respectively disposed at the opposite ends of the terminal assembly. The layers of the third insulating material are in fused relationship with the terminal pin and the ferrule and with the adjacent one of the first and second insulating materials.
