Abstract

A method is provided for automatically accommodating plugs having different contract layouts. Steps of the method include providing a jack assembly supporting a plurality of contacts accessible to a plug-receiving space, the plurality of contacts including eight contacts in side-by-side relation and two additional contact pairs positioned in opposed corners of the plug-receiving space, four central contacts of the eight side-by-side contacts defining bi-sectional members, and at least one capacitive element being provided in electrical communication with front end portions of at least two of the bi-sectional members. Noise generated through insertion of a plug into the plug-receiving space is automatically compensated for, whether the plug is an RJ-45 plug configured to interact with the eight contacts in side-by-side relation, or an IEC 60603-7-7 compliant plug configured to interact with at least the two additional contact pairs positioned in opposed corners.

Claims

1. A method for automatically accommodating plugs having differing contact layout geometries, comprising:

a. providing a jack assembly that defines a plug-receiving space, the jack assembly supporting a plurality of contacts accessible to the plug-receiving space, the plurality of contacts including;

(i) eight contacts in side-by-side relation, and (ii) two additional contact pairs positioned substantially in opposed corners of the plug-receiving space;

wherein four central contacts of the eight side-by-side contacts define bi-sectional members, and wherein the jack assembly further including at least one capacitive element in electrical communication with front end portions of at least two of the bi-sectional members;

b. inserting a plug into the plug-receiving space of the jack assembly, wherein the plug is selected from the group consisting of an RJ-45 plug configured to interact with the eight contacts in side-by-side relation and an IEC 60603-7-7 compliant plug configured to interact with at least the two additional contact pairs positioned substantially in opposed corners of the plug-receiving space; and

c. automatically compensating for noise generated through insertion of the plug into the plug-receiving space, regardless of the plug selection.

2. The method of claim 1, wherein the capacitive element is energized and generates compensation upon introduction of an RJ-45 plug configured to interact with the eight contacts in side-by-side relation.

3. The method of claim 1, wherein the capacitive element is not energized and does not generate compensation upon introduction of an IEC 60603-7-7 compliant plug configured to interact with at least the two additional contact pairs positioned substantially in opposed corners of the plug-receiving space.

4. The method of claim 1, wherein the jack assembly includes an insert housing member that includes an upper portion and a lower portion that cooperate to capture and support the plurality of contacts.

5. The method of claim 4, wherein the bi-sectional members are defined by a plurality of lead frames that include lead frames in a side-by-side orientation at at least one end of the insert housing member.

6. The method of claim 5, wherein the lead frames define two central pairs, and wherein the first and second contact pairs in the opposed corners of the jack assembly correspond to said two central pairs.

7. The method of claim 5, wherein the plurality of lead frames includes eight lead frames, and wherein each of the four central lead frames defines a bi-sectional structure.

8. The method of claim 5, wherein each of said bi-sectional members define a front end portion and a rear end portion, and wherein the front end portion and the rear end portion are supported in a cantilevered manner.

9. The method of claim 5, wherein the bi-sectional structure is adapted to move between a “

closed”

state wherein the at least one capacitive element is in electrical communication and energized with a circuit associated with the bi-sectional structure, and an “

open”

state wherein the at least one capacitive element is electrically isolated from the circuit.

10. The method of claim 9, wherein the at least one capacitive element is in communication with at least two of said plurality of lead frames.

11. The method of claim 5, wherein the at least one capacitive element includes a pair of spaced capacitive pads or plates.

12. The method of claim 11, further comprising a dielectric positioned between said spaced capacitive pads or plates.

13. The method of claim 5, wherein the at least one capacitive element includes interdigitated elements or fingers.

14. The method of claim 5, wherein the at least one capacitive element includes capacitive traces on a printed circuit board.

15. The method of claim 14, wherein the capacitive traces include at least one of capacitive pad traces, capacitive plate traces, and capacitive interdigitated traces.

16. The method of claim 14, wherein the printed circuit board supports a front end portion of at least one of said bi-sectional members in a cantilevered manner.
