Abstract

A telecommunications connector (10) comprises an array of contacts (12) connectable to telecommunications wire pairs, the contacts being of a first type or a second type. The first type of contact is shaped so that its contact region (12B) extends in a first direction and the second type of contact is shaped so that its contact region extends in an opposing direction. In an embodiment in the form of an RJ45 jack, to introduce crosstalk compensation, the contacts “3” to “6” in the inner zone of the array are alternately of the first and second types; and the contacts “1”, “2” and “7”, “8” of each pair in the remainder of the array are respectively of the same type but different from the adjacent contact in the inner zone.

Claims

1. A telecommunications connector having a jack form, comprising:

an array of eight contacts connectable to telecommunications wire pairs, comprising;

a first contact and a second contact of a first contact type and forming a first contact pair connectable to a first telecommunications wire pair;

a seventh contact and an eighth contact of a second contact type and forming a second contact pair connectable to a second telecommunications wire pair;

an inner zone comprising a third contact, a fourth contact, a fifth contact, and a sixth contact, the inner zone of contacts disposed between the first and second contact pairs, wherein the third and sixth contact are connectable to a third telecommunications wire pair and the fourth and fifth contact are connectable to a fourth telecommunications wire pair, wherein

each type comprises a support region by which the contact is mounted in the connector and a contact region positioned to make electrical connection with a respective contact of a mating telecommunications connector;

wherein, to introduce crosstalk compensation;

(i) the first type of contact is shaped so that its contact region extends in a first direction and the second type of contact is shaped so that its contact region extends in an opposing direction to the first direction;

(ii) adjacent contacts of the first zone of the array are alternately of the first and second types; and

(iii) the inner zone contact adjacent the first contact pair is of the second contact type, and the inner zone contact adjacent the second contact pair is of the first contact type, and wherein

the second type of contact is shaped so that engagement of the contact region by a respective electrical contact of the mating telecommunications connector moves a free end of the contact into engagement with a stop to enhance the electrical connection between the telecommunications connectors.

2. A connector as claimed in claim 1, in which the support region of each contact is joined to the contact region through at least one bend in the contact.

3. A connector as claimed in claim 1, in which at least one of the contacts has a deflection in the support region.

4. A connector as claimed in claim 1, in which the contacts are flexible, resilient contacts.

5. The combination of a connector as claimed in claim 1 in the form of a jack, and a mating plug.

6. A connector as claimed in claim 1, in which the support regions of the contacts are located in a printed circuit board and are connected to respective electrically-conductive traces on the board.

7. A connector as claimed in claim 6, in which the electrically-conductive traces connect the contacts to respective insulation displacement contacts connectable to respective wires of telecommunications wire pairs.

8. A connector as claimed in claim 1, in which the contact region of the first type of contact extends generally in the same direction as the support region of the contact, and the contact region of the second type of contact extends generally in the opposite direction to the support region of the contact.

9. A connector as claimed in claim 8, in which the support and contact regions of the first type of contact extend generally towards the direction from which a mating connector is introduced.

10. A connector as claimed in claim 9, in which at least one of the contacts of the first type comprises an intermediate portion, between the support and contact regions, that extends substantially perpendicular to the generally direction of extent of the contact.

11. A connector as claimed in claim 1, in which at least one of the contacts has a contact region that is joined to the support region by an intermediate portion that extends in a direction generally perpendicular to the direction of extent of the support and contact regions;

the contact being so shaped that engagement of the contact region by a respective electrical contact of the mating telecommunications connector moves the free end of the contact into engagement with a stop to enhance the electrical connection between the telecommunications connectors.

12. A connector as claimed in claim 11, in which at least one of the contacts has a deflection in the support region.

13. A connector as claimed in claim 11, in which contact region is joined to the intermediate portion through a bend in the contact region.

14. A connector as claimed in claim 13, in which the said bend in the contact region of each contact is engageable by a respective electrical contact of the mating telecommunications connector.
