Abstract

A coaxial connector comprising a male half of conventional construction and a female half having an annular electrical contact member which is a spring and which functions to provide continuous annular outer conductor electrical contact and RFI suppression. The annular spring member provides continuous annular outer conductor contact even during slight conductor misalignment or matched pairs not totally seated.

Claims

1. A connector assembly of the pluggable type for electrically coupling two ends of a coaxial circuit configuration including (A) a male plug assembly comprising (1) an electrically conductive inner conductor pin member for electrical connection to a coaxial circuit inner conductor, and (2) an electrically conductive outer conductor member, electrically isolated from and surrounding said electrically conductive pin member in part, and (B) a mating female receptacle assembly having a bore of generally complementary profile for accommodating said male plug assembly, said female receptacle assembly comprising (1) an electrically conductive inner conductor contact member for receiving and contacting said male plug assembly inner conductor pin member, (2) an electrically conductive outer conductor contact member electrically isolated from and surrounding said electrically conductive inner conductor contact assembly in part, for receiving and contacting said male plug assembly outer contact member, said female receptacle assembly outer conductor contact member having a resiliently flexible spring contact member which is (a) normally displaced in part from contact with said receptacle bore interior profile, and which, upon engagement of said male plug assembly electrically conductive outer conductor member (b) flexes outwardly to more closely conform to said receptacle bore interior profile, and which, upon continued insertion of said male plug assembly (c) presses progressively into engagement with said male plug assembly electrically conductive outer conductor member, and (3) an electrically conductive hood member electrically connected to and surrounding, in part, said female receptacle assembly inner conductor contact member, said resiliently flexible spring contact member having a generally outwardly directed integral flange at the male plug engaging end thereof, and a generally inwardly directed integral flange at the other end thereof, and said female receptacle assembly having an annular groove formed therein for accommodating said outwardly directed flange.

2. A connector assembly according to claim 1, wherein said resiliently flexible spring contact member is slotted adjacent its flanged ends thereby forming contact fingers.

3. A connector assembly according to claim 1, wherein said resiliently flexible spring contact member comprises a spring metal.

4. A connector assembly according to claim 1, wherein said electrically conductive hood member has a generally inwardly directed integral flange which terminates near the male plug engaging end of its associated electrically conductive inner conductive contact member.

5. A connector assembly according to claim 1, wherein said electrically conductive hood member comprises a metal.

8. A connector assembly according to claim 1, wherein said electrically conductive hood member comprises an electrically conductive elastomer.

9. A connector assembly according to any one of claims 1, 2, 3, 6, 4, 7, 5 or 8, the improvement wherein said mating inner contact members and said mating outer contact members, respectively, are generally circular in cross section.

6. A connector assembly of the pluggable type for electrically coupling two ends of a coaxial circuit configuration including (A) a male plug assembly comprising (1) an electrically conductive inner conductor pin member for electrical connection to a coaxial circuit inner conductor, and (2) an electrically conductive outer conductor member, electrically isolated from and surrounding said electrically conductive pin member in part, and (B) a mating female receptacle assembly having a bore of generally complementary profile for accommodating said male plug assembly, said female receptacle assembly comprising (1) an electrically conductive inner conductor contact member for receiving and contacting said male plug assembly inner conductor pin member, (2) an electrically conductive outer conductor contact member electrically isolated from and surrounding said electrically conductive inner conductor contact assembly in part, for receiving and contacting said male plug assembly outer contact member, said female receptacle assembly outer conductor contact member having a resiliently flexible spring contact member which is (a) normally displaced in part from contact with said receptacle bore interior profile, and which, upon engagement of said male plug assembly electrically conductive outer conductor member (b) flexes outwardly to more closely conform to said receptacle bore interior profile, and which, upon continued insertion of said male plug assembly (c) presses progressively into engagement with said male plug assembly electrically conductive outer conductor member, and (3) an electrically conductive hood member electrically connected to and surrounding, in part, said female receptacle assembly inner conductor contact member, said resiliently flexible spring contact member comprising an electrically conductive elastomer.

7. A connector assembly of the pluggable type for electrically coupling two ends of a coaxial circuit configuration including (A) a male plug assembly comprising (1) an electrically conductive inner conductor pin member for electrical connection to a coaxial circuit inner conductor, and (2) an electrically conductive outer conductor member, electrically isolated from and surrounding said electrically conductive pin member in part, and (B) a mating female receptacle assembly having a bore of generally complementary profile for accommodating said male plug assembly, said female receptacle assembly comprising (1) an electrically conductive inner conductor contact member for receiving and contacting said male plug assembly inner conductor pin member, (2) an electrically conductive outer conductor contact member electrically isolated from and surrounding said electrically conductive inner conductor contact assembly in part, for receiving and contacting said male plug assembly outer contact member, said female receptacle assembly outer conductor contact member having a resiliently flexible spring contact member which is (a) normally displaced in part from contact with said receptacle bore interior profile, and which, upon engagement of said male plug assembly electrically conductive outer conductor member (b) flexes outwardly to more closely conform to said receptacle bore interior profile, and which, upon continued insertion of said male plug assembly (c) presses progressively into engagement with said male plug assembly electrically conductive outer conductor member, and (3) an electrically conductive hood member electrically connected to and surrounding, in part, said female receptacle assembly inner conductor contact member, said electrically conductive hood member being slotted adjacent its flanged end thereby forming contact fingers.

10. The female half of a coaxial connector for use with a male half, and comprising (1) an electrically conductive circular outer conduit of generally circular cross-section, bored to receive and mating with the male half thereof, (2) an electrically conductive socket therein of generally circular cross-section adapted to receive and mate with an inner conductive generally cylindrical pin centrally disposed in said male half, (3) an electrical insulator supporting said socket within and spaced from said outer conduit but leaving the ends of said socket and outer conduit free, (4) and electrically conductive sheath surrounding and in contact with said socket, in part, and having an outer end adapted to make substantially 360°
