Abstract

A telecommunications connector includes a plug having plug contacts; an outlet having outlet contacts, the plug contacts making physical and electrical contact with the outlet contacts on a top surface of the outlet contacts; a compensation contact positioned beneath a bottom surface of the outlet contacts, the compensation contact being proximate to a location where the plug contacts make physical contact with the outlet contacts, the compensation contact providing crosstalk compensation for the telecommunications connector.

Claims

1. A telecommunications connector comprising:

a plug having plug contacts;

an outlet having outlet contacts, the plug contacts maling physical and electrical contact with the outlet contacts on a top surface of the outlet contacts;

a compensation contact positioned beneath a bottom surface of the outlet contacts, the compensation contact being proximate to a location where the plug contacts make physical contact with the outlet contacts, the compensation contact providing crosstalk compensation for the telecommunications connector.

2. The telecommunications connector of claim 1 wherein:

the outlet contacts and the compensation contact are physically supported on a printed circuit board in the outlet.

3. The telecommunications connector of claim 2 wherein:

the compensation contact is a spring contact having one end secured to the printed circuit board and a second end in physical contact with an outlet contact.

4. The telecommunications connector of claim 2 wherein:

the compensation contact is a pogo pin contact having one end secured to the printed circuit board and a second end in physical contact with an outlet contact.

5. The telecommunications connector of claim 2 wherein:

the compensation contacts includes a plurality of compensation contacts extending from the printed circuit board and running parallel to respective outlet contacts.

6. The telecommunications connector of claim 5 further comprising:

an insulative sheet positioned between the outlet contacts and the compensation contacts.

7. The telecommunications connector of claim 2 wherein:

the printed circuit board has an embedded component for compensating crosstalk in the telecommunications connector.

8. The telecommunications connector of claim 7 wherein:

the embedded component is at least one of resistance, capacitance and inductance.

9. The telecommunications connector of claim 1 wherein:

the compensation contact includes an arm extending from a first outlet contact, the arm passing under one or more outlet contacts, the compensation contact further including an extension off the arm, the extension passing under and parallel to a second outlet contact.

10. The telecommunications connector of claim 9 further comprising:

an insulative spacer between the arm and the outlet contacts and between the extension and the outlet contacts.

11. The telecommunications connector of claim 2 wherein:

the compensation contact makes direct physical and electrical contact with the outlet contact.

12. The telecommunications connector of claim 11 wherein:

the compensation contact is electrically connected to compensation elements on the printed circuit board.

13. The telecommunications connector of claim 2 wherein:

the compensation contact is insulated and is reactively coupled to the outlet contact.

14. The telecommunications connector of claim 13 wherein:

the compensation contact provides compensation without additional compensation elements.
