Abstract

An electrical connector includes electrical contacts that are configured to be mounted to an electrical cable, and mating ends that are configured to be surface mounted to a contact pad of an underlying substrate, such that the mating ends flex and apply a pressure against the contact pad.

First claim

What is claimed:

1. An electrical connector configured to be mounted to a substrate, the electrical connector comprising:
an electrically insulative connector housing body that defines:
a front end and a rear end opposite the front end along a longitudinal direction;
first and second sides that are spaced from each other along a lateral direction that is perpendicular to the longitudinal direction, wherein each of the first and second sides extends from the front end to the rear end; and
upper and lower ends spaced from each other along a transverse direction that is perpendicular to each of the lateral direction and the longitudinal direction, wherein the lower end is configured to face the substrate when the electrical connector is mounted to the substrate; and

at least one electrical contact supported by the connector housing body, wherein each electrical contact of one or more of at least one electrical contact defines:
a resilient and flexible mating end that extends out from the housing body a first distance along a first direction that includes at least one of the lateral direction and the longitudinal direction, and a second distance along the transverse direction that is less than the first distance; and
a mounting end opposite the mating end and configured to be mounted to an electrical cable,

wherein the electrical connector is configured to be mounted to the substrate such that the resilient and flexible mating end is configured to flex from a relaxed position when placed in surface contact with a respective electrical contact pad that is carried by a surface of the substrate, such that the mating end applies a pressure against the contact pad along the transverse direction so as to define a separable interface therewith, and
wherein the at least one electrical contact is configured to transmit data at frequencies between 5 GHz and 30 GHz while producing no more than −18 dB worst-case multi-active asynchronous cross talk.

2. The electrical connector as recited in claim 1 , wherein the mating end extends below the housing body when in the relaxed position.

3. The electrical connector as recited in claim 2 , wherein the mating end is disposed in a flexed position when the electrical connector is mounted to the substrate, the flexed position being disposed above the relaxed position.

4. The electrical connector as recited in claim 1 , wherein no straight line exists that extends perpendicular to the substrate surface and extends through the mating end twice.

5. The electrical connector as recited in claim 1 , wherein the at least one electrical contact comprises a plurality of electrical contacts configured as recited in claim 1 , and the at least one electrical cable comprises a corresponding plurality of electrical cables mounted to respective ones of the electrical contacts, and adjacent ones of the electrical contacts define differential signal pairs.

6. The electrical connector as recited in claim 1 , wherein the housing body defines a plurality of bays, each bay configured to receive an electrical cable.

7. The electrical connector as recited in claim 6 , further comprising a cover having a contact portion that covers the at least one electrical contact.

8. The electrical connector as recited in claim 6 , wherein the cover comprises a housing portion that covers at least a portion of the connector housing body.

9. The electrical connector as recited in claim 1 , wherein the at least one electrical contact is cantilevered from a surface of the housing body that does not face the substrate when the electrical connector is mounted to the substrate.

10. The electrical connector as recited in claim 1 , wherein the at least one electrical contact extends forward from a surface of the housing body to a location spaced forward from an entirety of the housing body.

11. The electrical connector as recited in claim 1 , wherein the first distance is at least 3 times greater than the second distance.

12. An electrical connector assembly comprising:
the electrical connector as recited in claim 1 ; and
at least one attachment mechanism configured to attach the electrical connector to the substrate so as to maintain the at least one electrical contact in a flexed position against the substrate.

13. The electrical connector assembly as recited in claim 12 , wherein the attachment mechanism includes an attachment beam configured to extend over at least a portion of the electrical connector, such that the portion of the electrical connector is disposed between the attachment beam and the substrate, the attachment beam configured to be attached to each of the electrical connector and the substrate so as to secure the electrical connector to the substrate.

14. The electrical connector assembly as recited in claim 13 , further comprising a cover that extends over the housing body, wherein the attachment beam is attached to the cover.

15. The electrical connector assembly as recited in claim 12 , wherein the at least one attachment mechanism includes a bracket assembly that is configured to secure the electrical connector to the substrate, wherein the bracket assembly includes a bracket body having a compression member and at least one attachment arm that extends from the compression member, the compression member configured to apply a downward force to the electrical connector along the transverse direction from the compression member towards the substrate.

16. The electrical connector assembly as recited in claim 15 , wherein the bracket assembly includes at least one fastening feature configured to attach the at least one attachment arm to the substrate.

17. The electrical connector assembly as recited in claim 15 , wherein the bracket assembly defines an insertion slot that extends between the compression member and the substrate in the longitudinal direction when the electrical connector is mounted to the substrate, wherein the insertion slot is configured to receive the electrical connector along the longitudinal direction such that the at least one electrical contact wipes against the at least one contact pad.

18. An electrical connector configured to be mounted to a substrate, the electrical connector comprising:
an electrically insulative connector housing body; and
at least one electrical contact supported by the connector housing body and cantilevered from a surface of the housing body that does not face the substrate when the electrical connector is mounted to the substrate, wherein each electrical contact of one or more of the at least one electrical contact defines a resilient and flexible mating end that extends out from the housing body, and a mounting end that is opposite the mating end and is configured to be mounted to an electrical cable,
wherein the at least one electrical contact is configured to transmit data at frequencies between 5 GHz and 30 GHz while producing no more than −18 dB worst-case multi-active asynchronous cross talk.

19. The electrical connector as recited in claim 18 , wherein the flexible mating end is configured to flex from a relaxed position when placed in surface contact with a respective electrical contact pad that is carried by a surface of the substrate such that the mating end applies a pressure against the contact pad so as to define a separable interface therewith, and the mating end extends below the housing body when in the relaxed position.

20. The electrical connector as recited in claim 19 , wherein the mating end is disposed in a flexed position when the electrica
