An electrical feedthrough for connecting electrical components on opposite sides of a bulkhead includes a conductive sleeve, and disposed within the sleeve is a dielectric body carrying an electrical conductor extending longitudinally of the sleeve. The electrical conductor is physically spaced and electrically insulated by the dielectric body from the conductive sleeve, and a part of the dielectric body is physically deformed to effect a hermetic seal with the conductive sleeve and/or electrical conductor. In the method of assembly of the electrical feedthrough of the subject invention, a part of the dielectric body is deformed to effect the hermetic seal.

Electrical feedthrough devices

An electrical feedthrough capable of connecting electrical components on opposite sides of a bulkhead includes a feedthrough housing having hermetically sealed therein a hermetic sub-assembly consisting of an electrical conductor concentrically disposed within a dielectric body which, in turn, is disposed within a conductive sleeve. The hermetic sub-assembly is sealed to the feedthrough housing by a flange which projects outwardly relative to the conductive sleeve, and which flange is physically deformed against the internal surface of the feedthrough housing. In the method for making the electrical feedthrough according to the invention, the connecting component is hermetically sealed within the connector body physically deforming a flange projecting outwardly relative to the conductive sleeve against an internal surface of the feedthrough housing.
