Abstract

A hermetic pressure connector which provides a pressure-tight, electrically conductive connection through a hole in a bulkhead. The connector includes a transverse support member having a high pressure side and an opposite low pressure side. A passage extends through the transverse support member between the opposite sides. A conductor pin having an axial portion extends through the passage. An insulating sleeve surrounds at least the axial portion of the conductor pin, thereby electrically insulating the transverse support member from the conductor pin. A molded connected body surrounds at least a central portion of the conductor pin at least at one of the high and low pressure sides to thereby mechanically support the conductor pin in the passage. The molded connector body is directly sealingly engaged with the conductor pin, the insulating sleeve and the transverse support member.

Claims

1. A hermetic pressure connector for providing a pressure-tight, electrically conductive connection through a hole in a bulkhead, the connector comprising:

a transverse support member having a high pressure side and an opposite low pressure side with a passage extending through the transverse support member between the opposite sides;

a conductor pin having an axial portion extending through the passage;

an insulating sleeve surrounding at least the axial portion of the conductor pin thereby electrically insulating the transverse support member from the conductor pin, wherein the insulating sleeve is a two-piece insert; and

a molded connector body surrounding at least a central portion of the conductor pin at least at one of the high and low pressure sides to thereby mechanically support the conductor pin in the passage, the molded connector body being directly sealingly engaged with the conductor pin, the insulating sleeve and the transverse support member.

16. The hermetic pressure connector of claim 1, wherein the molded connector body comprises a polymeric material.

2. The hermetic pressure connector of claim 26, wherein the transverse support member includes a plurality of passages and there is a corresponding plurality of conductor pins having axial portions extending through respective passages, each conductor pin including the sulating sleeve surrounding the axial portion.

3. The hermetic pressure connector of claim 26, wherein the transverse support member is constructed of a metallic material.

4. The hermetic pressure connector of claim 26, wherein the conductor pin includes a circumferential interlocking member encased by the molded connector body for interlocking the conductor pin and the molded connector body.

5. The hermetic pressure connector of claim 29, wherein the circumferential interlocking member includes a circumferential groove formed in the conductor pin.

6. The hermetic pressure connector of claim 26, wherein the transverse support member includes a dovetail retention feature interlocking the transverse support member to the molded connector body.

7. The hermetic pressure connector of claim 26, wherein a circumferential groove is formed in an external surface of the molded connector body.

8. The hermetic pressure connector of claim 26, wherein the molded connector body further includes a coupling ridge to retain a receptacle thereon.

9. The hermetic pressure connector of claim 26, wherein the conductor pin comprises beryllium copper.

10. The hermetic pressure connector of claim 26, wherein the molded connector body surrounds the central portion of the conductor pin beyond the passage at the high pressure side.

11. The hermetic pressure connector of claim 26, wherein the molded connector body surrounds the central portion of the conductor pin beyond the passage at the low pressure side.

12. The hermetic pressure connector of claim 26, wherein the molded connector body extends beyond the transverse support member at least at one of the high and low pressure sides.

13. The hermetic pressure connector of claim 26, wherein the transverse support member comprises a plate, at least a portion of which is embedded in the molded connector body.

14. The hermetic pressure connector of claim 38, wherein the plate has an outside diameter that is substantially equal to an outside diameter of the molded connector body.

15. The hermetic pressure connector of claim 26, wherein the transverse support member has an outside diameter that is substantially equal to an outside diameter of the molded connector body.

17. The hermetic pressure connector of claim 41, wherein the conductor pin and transverse support member are insert-molded with the polymeric connector body.

18. The hermetic pressure connector of claim 26, wherein the two-piece insert has one piece constructed of a relatively high strength material and the other piece is constructed of a relatively lower strength material.

19. The hermetic pressure connector of claim 43, wherein the high strength material is a ceramic.

20. The hermetic pressure connector of claim 43, wherein the low strength material is a polymeric material.
