Abstract

A high density rectangular electrical interconnect is disclosed that includes a plug having a plurality of plug contacts mated to a receptacle having a plurality of spring contacts preloaded with an opening force to reduce mating force. The plurality of plug contacts may be a plurality of pin contacts, printed circuit board traces, or flexible film contacts. The plug and receptacle may include shields and/or shielding material that form a continuous shield around the mated plug and spring contacts.

Claims

1. An electrical connector, comprising:

a plug comprising;

a plug shell;

a plug sub-assembly housing disposed within the plug shell; and

at least one plug contact sub-assembly disposed within the plug sub-assembly housing, the at least one plug contact sub-assembly comprising a plurality of plug contacts, a plug sub-assembly base and a plug contact alignment spacer; and

a receptacle comprising;

a receptacle shell;

a receptacle sub-assembly housing assembled to the receptacle shell; and

at least one spring contact sub-assembly disposed within the receptacle sub-assembly housing, the at least one spring contact sub-assembly comprising a plurality of spring contacts, a sub-assembly base, a contact alignment spacer, and a spring contact assembler;

wherein the plug and receptacle are configured to mate, thereby mating the plurality of plug contacts and the plurality of spring contacts.

2. The electrical connector of claim 1, wherein the plug further comprises a plug shield disposed around the at least one plug contact sub-assembly and the receptacle further comprises a receptacle shield disposed around the at least one spring contact sub-assembly, the plug and receptacle configured to electrically contact the plug shield and receptacle shield when mated.

3. The electrical connector of claim 2, wherein the plug shield is a body disposed around the at least one plug contact sub-assembly.

4. The electrical connector of claim 2, wherein the plug shield is an electrical shielding material plated on an exterior surface of the plug sub-assembly housing.

5. The electrical connector of claim 2, wherein the receptacle shield is a body disposed around the at least one spring receptacle sub-assembly.

6. The electrical connector of claim 2, wherein the receptacle shield is an electrical shielding material plated on an inside surface of the receptacle plug.

7. The connector of claim 1, wherein the plug sub-assembly housing comprises a plug sub-assembly housing disposed within a plug shield.

8. The connector of claim 1, wherein the plug sub-assembly housing comprises a plug sub-assembly support structure configured to receive and support the at least one plug contact sub-assembly.

9. The connector of claim 1, wherein the receptacle sub-assembly housing comprises at least one spring contact sub-assembly support slot including guide rails configured to receive and support the at least one spring contact sub-assembly.

10. The connector of claim 1, wherein the plurality of spring contacts are preloaded with an opening force.

11. The connector of claim 1, wherein the receptacle sub-assembly includes a retaining surface configured to preload the plurality of spring contacts with an opening force.

12. The connector of claim 1, wherein the plug contacts are stitched contacts.

13. The connector of claim 1, wherein the plurality of plug contacts are disposed on a printed circuit board.

14. The connector of claim 1, wherein the plurality of plug contacts are disposed on a flexible film contact assembly.

15. An electrical connector comprising

a plug comprising:

a plug shell;

a plug sub-assembly housing disposed within the plug shell;

at least one plug contact sub-assembly disposed within the plug sub-assembly housing, the at least one plug contact sub-assembly comprising a plurality of plug contacts; and

a plug shield disposed around the at least one plug contact sub-assembly, the plug shield comprising two hermaphroditic plug shield portions; and

a receptacle comprising;

a receptacle shell;

a receptacle sub-assembly housing assembled to the receptacle shell;

at least one spring contact sub-assembly disposed within the receptacle sub-assembly housing, the at least one spring contact sub-assembly comprising a plurality of spring contacts; and

a receptacle shield which is a body disposed around the at least one spring contact sub-assembly

wherein the plug and receptacle are configured to mate, thereby mating the plurality of plug contacts and the plurality of spring contacts and electrically contacting the plug shield and the receptacle shield.

16. An electrical connector comprising

a plug comprising:

a plug shell comprising two hermaphroditic plug shell portions;

a plug sub-assembly housing disposed within the plug shell; and

at least one plug contact sub-assembly disposed within the plug sub-assembly housing, the at least one plug contact sub-assembly comprising a plurality of plug contacts; and

a receptacle comprising;

a receptacle shell;

a receptacle sub-assembly housing assembled to the receptacle shell; and

at least one spring contact sub-assembly disposed within the receptacle sub-assembly housing, the at least one spring contact sub-assembly comprising a plurality of spring contacts;

wherein the plug and receptacle are configured to mate, thereby mating the plurality of plug contacts and the plurality of spring contacts.
