Abstract

A communication connector having a plurality of contact pairs for conductive connection to respective communication signal wire pairs is provided with a capacitor label that capacitively couples a first contact of one contact pair to a second contact of a second contact pair to reduce near end cross talk between adjacent contacts. A common conductive lamina disposed closely adjacent to and spaced from more than one of the contacts further improves near end cross talk performance of the communication connector.

Claims

1. A capacitor label for a communication connector having a plurality of contact pairs disposed in a substantially parallel array for conductive connection to respective communication signal wire pairs, comprising:

capacitor means formed on the capacitor label for capacitively coupling a first contact of one contact pair to a second contact of a second contact pair; and

a common conductive lamina disposed closely adjacent to an outer insulating surface of the capacitor label, the common conductive lamina being of sufficient extent to extend across and along the contact array of the contact pairs such that crosstalk is reduced between the contact pairs.

2. A capacitor label as set forth in claim 1, wherein the capacitor means includes a multilayer label having first and second spaced apart conductive lamina separated by a dielectric and wherein the first conductive lamina is conductively joined to the first contact and the second conductive lamina is conductively joined to the second contact.

3. A capacitor label as set forth in claim 2, including conductive adhesive means for joining each of the first and second contacts to each respective first and second conductive lamina.

4. A capacitor label as set forth in claim 3, wherein the common and first and second conductive laminas are printed layers of conductive silver ink and the dielectric is a printed insulating lamina.

5. A capacitor label as set forth in claim 4, wherein the capacitor label includes an outer adhesive surface for securing the label to the contacts.

6. A capacitor label as set forth in claim 2, wherein the common conductive lamina is a metal foil.

7. A capacitor label as set forth in claim 1, wherein the capacitor means includes a multilayer label having a first conductive lamina separated from the contacts by a dielectric with the first conductive lamina being conductively joined to the first contact and the first conductive lamina including an elongate portion that extends along a portion of the second contact a distance sufficient to capacitively couple the first conductive lamina to the second contact.

8. A capacitor label as set forth in claim 7, including conductive adhesive means for joining the one contact to the first conductive lamina.

9. A capacitor label as set forth in claim 8, wherein the common and the first conductive laminas are printed layers of conductive silver ink and the dielectric is a printed insulating lamina.

10. A capacitor label as set forth in claim 9, wherein the capacitor label includes an outer adhesive surface for securing the label to the contacts.

11. A capacitor label as set forth in claim 7, wherein the common conductive lamina is a metal foil.

12. A capacitor label as set forth in claim 1, wherein the capacitor means includes a capacitor label having a first conductive lamina separated from the contacts by a dielectric and the first conductive lamina including elongate portions that extend along portions of the first and second contacts a distance sufficient to capacitively couple the first conductive lamina to each of the first and second contacts.

13. A capacitor label as set forth in claim 12, wherein the common and the first conductive laminas are printed layers of conductive silver ink.

14. A capacitor label as set forth in claim 13, wherein the capacitor label includes an outer adhesive surface for securing the label to the contacts.
