Title: Electrical connector with metal to metal seal
Claims: I claim: 1. An electrical connector comprising: first and second connecting members; the first member including a housing with an aperture, a mating section of metallic construction having a first radial face peripherally extending about the aperture, and a shroud member axially extending from said first face towards the second member and generally parallel to the aperture to define an enlarged opening, the second member including a sleeve having an interior and a mating portion, and contact means carried by said sleeve and arranged to extend into said aperture in response to the receipt of said mating portion in said enlarged opening, and means for coupling said first and second members in conjunction with the movment of said mating portion axially within said shroud member, said mating portion including a front section of reduced outer diameter and a radial flange having an inner end rigidly fixed on the front section and at least one deflectable integral beam section extending outwardly therefrom for engagement with said first radial face, said one beam section having a portion of metallic construction facing said first radial face with radially inner and outer frontwardly converging surfaces and an axially extending cutting edge formed thereby with a hardness greater than that of said metallic section for sealing penetration of said first radial face in response to the coupling of said first and second members, said cutting edge being disposed outwardly beyond said inner end and peripherally about said aperture. 2. The electrical connector of claim 1 wherein said housing is of metallic construction and extends outwardly from said radial face to form said shroud member. 3. The electrical connector of claim 2 wherein said sleeve is of metallic construction and said means for coupling includes means for rotationally coupling the sleeve to the shroud member. 4. The electrical connector of claim 1 wherein said flange includes a first deflectable beam section with said inner end rigidly fixed on said front section and a second deflectable beam section with an end rigidly fixed on said first beam section, said second beam section including said converging surfaces and said cutting edge. 5. The electrical connector of claim 1 wherein said means includes rotational coupling means internally on the shroud member and externally on the sleeve whereby said sleeve moved rotationally and axially into said shroud member. 6. The electrical connector of claim 1 wherein said beam section is of reduced size compared to said enlarged opening and is capable of deflection without engaging said shroud member. 7. The electrical connector of claim 1 wherein said deflectable section is deflectable by engagement with said radial face in a direction away from said radial face, and said inner radial surface with said radial face forms an acute angle less than about 45.degree. and an area of pressure engagement which is increased during penetration of said radial face. 8. An electrical connector comprising: first and second connecting members; the first member including a metallic housing with an aperture, a mating section integral with the housing having a first radial face peripherally extending about the aperture and facing said second member and a shroud member integral with the housing axially extending from the face towards the second member to define an enlarged opening, the second member including a metallic sleeve having an interior and a mating portion integral with the sleeve, contact means disposed in the interior and arranged to extend into the enlarged opening, and insulating means disposed between the sleeve and contact means, said mating portion including a front section of reduced outer diameter and a radial flange having an inner end rigidly fixed on the front section and a deflectable integral beam section extending outwardly therefrom for engagement with said first radial face, said beam section having a portion of metallic construction facing said first radial face with radially inner and outer frontwardly converging surfaces and an axially extending cutting edge formed thereby with a hardness greater than that of said metallic section for sealing penetration of said radial surface, said edge being disposed outwardly beyond said inner end and peripherally about said aperture for deflection away from said first radial face in response to the engagement of said cutting edge with said first radial face, and means for coupling said first and second members including cooperating rotational coupling means internally integral with the shroud member and externally integral with the sleeve whereby said sleeve is moved axially into the shroud to rotate the radial flange and axially extending cutting edge with respect to the first radial face and simultaneously engage said cutting edge with said first radial face. 9. The electrical connector of claim 8 wherein said inner radial surface with said radial face forms an acute angle less than about 45.degree.. 10. The electrical connector of claim 9 wherein said inner converging surface is rectilinearly longer than said outer converging surface. 11. The electrical connector of claim 10 wherein said outer converging surface forms a second acute angle with said radial surface which is greater than the acute angle formed by said inner surface and said beam section is of reduced size compared to said enlarged opening. 12. An electrical connecting member for sealing penetration with a radial surface of a mating connecting member and comprising: contact means, insulating means receiving said contact means, and housing means for said contact means and insulating means including a metal sleeve having a longitudinal axis and an interior portion, and means for axially coupling said sleeve to said mating member, said sleeve including a front reduced diameter section and a radial flange having an inner end rigidly fixed on the front section and a deflectable integral beam section extending radially outwardly therefrom for engagement with said radial surface in response to the axial coupling of said sleeve to said mating member and deflectable by said engagement in a direction away from said radial surface, said beam section having a portion of metallic construction facing said radial surface with radially inner and outer frontwardly converging surfaces and an axially extending cutting edge formed thereby with a hardness greater than that of said radial surface, said edge being disposed radially outwardly of said inner end, said inner frontwardly converging surface forming an acute angle less than about 45.degree. to increase the area of pressure engagement between said inner frontwardly converging surface and said radial surface during the penetration of said radial surface. 13. The connector of claim 12 wherein said outer converging surface forms a second acute angle with said radial surface which is greater than the acute angle formed by said inner surface. 14. The electrical connector of claim 12 wherein said actue angle is between about 20.degree.-40.degree.. 15. The electrical connector of claim 12 wherein said inner converging surface is rectilinearly longer than said outer converging surface. 16. The electrical connector of claim 13 wherein said acute angle between said inner surface and radial surface is between about 20.degree.-40.degree. and said inner converging surface is rectilinearly longer than said outer surface. 17. For use with a metallic connector member having a first annular sleeve portion including a radially inwardly extending shoulder formed in said sleeve portion with a coaxial passageway therein for receiving a contact carried by a second sleeve member threadingly received in said first annular sleeve portion, the improvement comprising: an annular stem projecting from said second sleeve member, an annular flange on said stem extending radially outwardly of said stem and spaced from said second sleeve member with said annular flange having a radial end face and said contact extending through said stem and flange past said radial end face for receipt in said passageway, and an axially projecting annular tooth of harder material than said shoulder formed on said radial end face with said tooth located radially outwardly of said stem for engagement with said shoulder in response to the threading receipt of said second sleeve member in said first annular sleeve portion to cut a complimentary surface in said shoulder with the portion of said flange extending radially outwardly of said tooth flexing axially toward said second sleeve member for applying a spring force between said flange and shoulder for sealing the periphery of said passageway from the periphery of said flange.
