Abstract

A high performance, high capacitance gain, electric connector for data transfer applications. At least eight sequentially positioned elongate contact members are connected in a series of signal pairs. A first signal pair includes a fourth contact member and a fifth contact member. A second signal pair includes a third contact member and a sixth contact member. In addition, a third signal pair comprises a first contact member and a second contact member. Finally, a seventh and an eighth contact member are in a fourth signal pair. One member of each contact member pair is configured differently from the other member of the pair, the respective contact members being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths. Each of the third and fifth contact members mounts a plate-like extension oriented in a first direction and in respective planes generally parallel to one another. Each pair of extensions are separated by a first dielectric such that a first capacitor is formed. Furthermore, each of the fourth and sixth contact members mounts a plate-like extension oriented in a second direction and also in respective planes generally parallel to one another. Each pair of extensions are likewise separated by a second dielectric such that a second capacitor is formed. Each contact of each contact member pair has a plug engaging portion and a board engaging portion, the plurality of contact members having a selected shape, being arranged relative to one another, and being housed collectively by a dielectric casing so as to minimize crosstalk during data transfer.

Claims

1. A high performance, high capacitance gain, electric connector for data transfer applications, which comprises:

at least eight sequentially positioned elongate contact members connected in a plurality of signal pairs;

a first signal pair including a fourth contact member and a fifth contact member, and a second signal pair comprising a third contact member and a sixth contact member;

each of the third and fifth contact members mounting a plate-like extension oriented in a first direction and in respective planes generally parallel to one another, each pair of extensions being separated by a first dielectric having a relatively high dielectric value such that a first high gain capacitor is formed;

each of the fourth and sixth contact members mounting a plate-like extension oriented in a second direction and in respective planes generally parallel to one another, each pair of extensions being separated by a second dielectric having a relatively high dielectric value such that a second high gain capacitor is formed;

the first direction being generally convergent with the second direction; and

each contact member of each contact member pair including a plug engaging portion and a board engaging portion, the plurality of contact members having a selected shape, being arranged relative to one another, and being housed collectively by a dielectric casing so as to minimize crosstalk during high frequency data transfer.

2. The electric connector set forth in claim 1 wherein at least one of the dielectrics comprises a polymeric material.

3. The electric connector set forth in claim 1 wherein the casing comprises a polymeric material having a relatively high dielectric value.

4. The electric connector set forth in claim 1 wherein at least one of the conductive members includes commercially pure copper.

5. The electric connector set forth in claim 1 wherein at least one of the capacitors is a flat plate capacitor.

6. The electric connector set forth in claim 1 wherein each conductive member having a plate-like extension is formed with the extension as a one piece unit.

7. The electric connector set forth in claim 1 wherein the total surface area of the extensions of the first capacitor is generally equivalent to that of the second capacitor extensions.

8. The electric connector set forth in claim 1 wherein the total surface area of the extensions of the first capacitor is generally unequal to that of the second capacitor extensions.

9. A high performance, high capacitance gain, electric connector for data transfer applications, which comprises:

at least eight sequentially positioned contacts connected in a plurality of signal pairs;

one contact of each pair being configured differently from the other contact of the pair, and the respective contacts of each pair being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths;

one contact of each of the first, third and fourth signal pairs crossing over the other contact of the pair so as to reverse the positions occupied by the respective contacts along their non-parallel paths;

each of the third and fifth contacts mounting a plate-like extension oriented in a first direction and in respective planes generally parallel to one another, each pair of extensions being separated by a first dielectric such that a first capacitor is formed;

each of the fourth and sixth contacts mounting a plate-like extension oriented in a second direction and in respective planes generally parallel to one another, each pair of extensions being separated by a second dielectric such that a second capacitor is formed;

the first direction being generally convergent with the second direction; and
