US 2018/0026237 A1 · FEEDTHROUGH DEVICE

Abstract

In a feedthrough device and method of assembly thereof, a body has longitudinally spaced first and second end faces and an inner surface defining a longitudinally extending opening. A conductor extends within the opening and an insulator extends within the opening transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body. The body has at least one indentation formed longitudinally into at least one of the first and second end faces, with a portion of the inner surface of the body being displaced transversely against the insulator in correspondence with the at least one longitudinal indentation to crimp the insulator and conductor within the opening of the body and maintain a hermetic seal across the feedthrough device.

Dependent claims

A feedthrough device comprising:

a body having longitudinally spaced first and second end faces and an inner surface defining an opening extending longitudinally through the body;
a conductor extending within the opening of the body;
an insulator extending within the opening of the body transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body;
at least one indentation formed longitudinally into at least one of the first and second end faces of the body;
and
at least one annular bulge formed in the inner surface of the body and longitudinally corresponding to the at least one indentation, wherein the at least one annular bulge extends transversely of the body opening such that the annular bulge crimps the insulator and the conductor to form a hermetic seal.
