Abstract
Abstract 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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
96 words
An electrical feedthrough comprising a feedthrough housing and, hermetically sealed therein, a hermetic sub-assembly including a conductive sleeve and, disposed within the sleeve a dielectric body carrying a conductor which extends longitudinally of the sleeve, wherein the hermetic sub-assembly is sealed to the feedthrough housing by a flange which projects outwardly relative to the sleeve, and which is physically deformed against an internal surface of the feedthrough housing, with the deformation of the flange comprising a partial shearing thereof against an edge formed by a peripheral step provided on the internal surface of the feedthrough housing.
Claim 2
Dependent Claim
96 words
An electrical feedthrough comprising a feedthrough housing and, hermetically sealed therein, a hermetic sub-assembly including a conductive sleeve and, disposed within the sleeve a dielectric body carrying a conductor which extends longitudinally of the sleeve, wherein the hermetic sub-assembly is sealed to the feedthrough housing by a flange which projects outwardly relative to the sleeve, and which is physically deformed against an internal surface of the feedthrough housing, with the deformation of the flange comprising a partial shearing thereof against an edge formed by a peripheral step provided on the internal surface of the feedthrough housing.
Claim 3
Dependent Claim
21 words
An electrical feedthrough according to claim 1 wherein the flange is integrally formed with the conductive sleeve of the hermetic sub-assembly.
Claim 4
Dependent Claim
33 words
an electrical feedthrough according to claim 2 wherein the partial shear of the flange lies between the peripheral step and a complementary stepped portion of a sealing member disposed within the feedthrough housing.
Claim 5
Dependent Claim
32 words
An electrical feedthrough according to claim 3 wherein the sealing member comprises a bush disposed about a part of the sleeve and having said complementary stepped portion formed at one end thereof.
Claim 6
Dependent Claim
17 words
An electrical feedthrough according to claim 4 wherein the flange projects at one end of the sleeve.
Claim 7
Dependent Claim
18 words
An electrical feedthrough according to claim 4 wherein the flange projects at an intermediate point on the sleeve.
Claim 8
Dependent Claim
18 words
An electrical feedthrough according to claim 1 wherein the flange comprises a shear ring about the hermetic sub-assembly.
Claim 9
Dependent Claim
37 words
An electrical feedthrough according to claim 7 wherein the partial shear of the shear ring lies between the peripheral step and a complementary stepped portion on the outer surface of the conductive sleeve of the hermetic sub-assembly.
Claim 10
Dependent Claim
23 words
An electrical feedthrough according to claim 8 wherein the sleeve is integrally formed with a shearing collar which provides said complementary stepped portion.
Claim 11
Dependent Claim
30 words
An electrical feedthrough according to claim 9 and including a thrust member in the form of a bush disposed about a part of the sleeve and abutting the shearing collar.
Claim 12
Dependent Claim
25 words
An electrical feedthrough according to claim 1 wherein the hermetic sub-assembly itself comprises the electrical feedthrough, and the feedthrough housing thereof constitutes the conductive sleeve.
Claim 13
Independent Claim
69 words
A method of making an electrical feedthrough comprising disposing within a feedthrough housing a hermetic sub-assembly including a conductive sleeve and disposed within the sleeve a dielectric body carrying a conductor which extends longitudinally of the sleeve, and hermetically sealing the connecting component within the connector body by physically deforming by partial shearing a flange projecting outwardly relative to the sleeve against an internal surface of the feedthrough housing.
Claim 14
Independent Claim
69 words
A method of making an electrical feedthrough comprising disposing within a feedthrough housing a hermetic sub-assembly including a conductive sleeve and disposed within the sleeve a dielectric body carrying a conductor which extends longitudinally of the sleeve, and hermetically sealing the connecting component within the connector body by physically deforming by partial shearing a flange projecting outwardly relative to the sleeve against an internal surface of the feedthrough housing.
