Abstract

A hermaphroditic self shorting electrical connector including a housing, a plurality of electrical terminals supported within the housing and electrical shunt apparatus including at least one resilient conductive member, positioned and configured such that when the connector is in an unmated condition the resilient conductive member is in electrical contact with at least two electrical terminals and such that mating engagement of the connector with a corresponding connector deflects the resilient conductive member such that it is no longer in electrical contact with at least one of the at least two electrical terminals. A latch mechanism which is resistant to unwanted decoupling and an arrangement for providing a shield grounding connection to a mounting panel are also disclosed.

Claims

1. A hermaphroditic self shorting electrical connector comprising:

a housing;

a plurality of electrical terminals supported within the housing; and

electrical shunt means including at least one resilient conductive member, in the general form of a spiral spring, positioned and configured such that when the connector is in an unmated condition the resilient conductive member is in electrical contact with at least two electrical terminals and such that mating engagement of the connector with a corresponding connector deflects the resilient conductive member such that it is no longer in electrical contact with at least one of the at least two electrical terminals.

2. A connector according to claim 1 and wherein said resilient conductive member is preloaded against said at least two electrical terminals.

3. A connector according to claim 1 and also comprising:

at least first latch means pivotably mounted on the housing and including a front portion arranged for engagement with a corresponding connector and a rear portion arranged for engagement with the housing for preventing inadvertent disengagement of mated connectors.

4. A connector according to claim 2 and also comprising:

at least first latch means pivotably mounted on the housing and including a front portion arranged for engagement with a corresponding connector and a rear portion arranged for engagement with the housing for preventing inadvertent disengagement of mated connectors.

5. A connector according to claim 1 and also comprising:

a unitary electrical shield disposed within the housing, at least partially surrounding the electrical terminals.

6. A connector according to claim 2 and also comprising:

a unitary electrical shield disposed within the housing, at least partially surrounding the electrical terminals.

7. A connector according to claim 3 and also comprising:

a unitary electrical shield disposed within the housing, at least partially surrounding the electrical terminals.

8. A connector according to claim 4 and also comprising:

a unitary electrical shield disposed within the housing, at least partially surrounding the electrical terminals.

9. A connector according to claim 1 and also comprising:

electrical shielding means including at least one integrally formed conductive portion for providing automatic grounding of the connector when it is coupled onto a conductive panel having IBM standard connection apertures.

10. A connector according to claim 5 wherein said unitary electrical shield includes at least one integrally formed conductive portion for providing automatic grounding of the connector when it is coupled onto a conductive panel having IBM standard connection apertures.

11. A connector according to claim 1 and also comprising:

external cable engagement means selectably mountable on the exterior of the housing for retaining a cable extending through a cable access port in the housing, in a desired bent orientation.

12. A connector according to claim 2 and also comprising:

external cable engagement means selectably mountable on the exterior of the housing for retaining a cable extending through a cable access port in the housing, in a desired bent orientation.

13. A connector according to claim 9 and also comprising:

external cable engagement means selectably mountable on the exterior of the housing for retaining a cable extending through a cable access port in the housing, in a desired bent orientation.

14. A connector according to claim 5 and also comprising:

external cable engagement means selectably mountable on the exterior of the housing for retaining a cable extending through a cable access port in the housing, in a desired bent orientation.

15. A connector according to claim 1 and wherein said electrical terminals are directly connectable to a printed circuit board.

16. A connector according to claim 15 and wherein said electrical terminals are configured to provide a straight connection to a printed circuit board.

17. A connector according to claim 15 and wherein said electrical terminals are configured to provide a side-going connection to a printed circuit board.
