Abstract

An electrical contact for transmitting power to a printed circuit structure. The power contact comprises a main section that includes a first edge and an opposing second edge, and is made from electrically conductive material. A current-receiving interface is disposed between the main section first and second edges. And a plurality of terminals extend from the main section along the second edge. A void of electrically conductive material is formed in the main section for guiding current flow from the current-receiving interface to the terminals.

Claims

1. A power contact, comprising:

a main section including a first edge and an opposing second edge, and being made from electrically conductive material;

a current-receiving interface disposed between the first edge and the second edge;

a plurality of terminals extending from the main section and along the second edge; and

at least one void of electrically non-conductive material formed in the main section for guiding current flow from the current-receiving interface to the plurality of terminals such that current is distributed among individual terminals of the plurality of terminals, wherein the at least one void does not separate the main section into multiple pieces.

2. The power contact of claim 1, wherein the at least one void includes a longitudinally-extending slot extending from the current-receiving interface to a position proximate a central region of the main section.

3. The power contact of claim 1, wherein the at least one void includes two slots.

4. The power contact of claim 1, wherein the at least one void includes a first slot extending into the main section from the current-receiving interface and a second slot in the main section that is spaced apart from the first slot.

5. The power contact of claim 1, wherein the current-receiving interface includes at least one cantilevered beam.

6. An electrical connector, comprising:

an insulative housing; and

a power contact according to claim 1 disposed in the insulative housing.

7. A power contact, comprising:

a main section including a current-receiving interface and being made from electrically conductive material;

a plurality of terminals extending from the main section for engaging a printed circuit structure, the plurality of terminals including a first terminal that is closest to the current-receiving interface and a second terminal that is farthest from the current-receiving interface; and

a slot disposed in the main section extending from a position proximate the current-receiving interface to a position that is between the first terminal and the second terminal.

8. The power contact of claim 7, further comprising a second slot disposed in the main section and positioned above the second terminal.

9. The power contact of claim 7, wherein the current-receiving interface includes one or more cantilevered beams extending from the main section.

10. The power contact of claim 7, wherein the current-receiving interface includes an upper interface and a lower interface, each of the upper and lower interfaces comprising at least one cantilevered beam.

11. The power contact of claim 10, wherein the slot is disposed between the upper interface and the lower interface.

12. An electrical connector, comprising:

an insulative housing; and

a power contact according to claim 7 disposed in the insulative housing.

13. The power contact of claim 7, wherein the power contact is a one-piece design.

14. A power contact, comprising:

a main section including two or more electrically interconnected, individual strips of electrically conductive material;

a current-receiving interface extending from a first edge of the main section; and

a plurality of terminals extending from a second edge of the main section for engagement with a printed circuit; and

individual strips of electrically non-conductive material interspersed with the individual strips of electrically conductive material.

15. The power contact of claim 14, wherein interconnectivity is proximate the current-receiving interface.

16. The power contact of claim 14, wherein interconnectivity is proximate the plurality of terminals.

17. The power contact of claim 14, wherein interconnectivity is both proximate the current-receiving interface and the plurality of terminals.

18. The power contact of claim 14, wherein the individual strips of electrically conductive material and the individual strips of electrically non-conductive material lie in the same plane such that the materials are coterminous widthwise.

19. The power contact of claim 14, wherein an air gap exists between at least some of the individual strips of conductive material.

20. A power contact, comprising a main body section, a first and a second contact beam extending from a first edge of the main body section, and a contact terminal extending from a second edge of the main body section, wherein the main body section has a void formed therein, the void extends from the first edge of the main body section, and the void defines a first discrete current flow pathway to and from the first contact beam, and a second discrete current flow pathway to and from the second contact beam.

21. The power contact of claim 20, wherein the first discrete current flow pathway extends along one side of the void, and the second discrete current flow pathway extends along another side of the void.

22. The power contact of claim 20, wherein the first discrete current flow pathway adjoins the second discrete current flow pathway proximate an end of the void.
