Claim 7:
8. A circuit board, comprising:
an edge connector at an edge of the circuit board, the edge being a plugging end of the edge connector and the edge connector comprising a first row and a second row of golden fingers; and
one or more circuits, each golden finger of the edge connector being coupled to a circuit of the one or more circuits;
wherein the first row of golden fingers is adjacent to the plugging end and includes a first plurality of golden fingers disposed in parallel and isolated from each other on the circuit board, and the second row of golden fingers includes a second plurality of golden fingers disposed in parallel and isolated from each other on the circuit board, the second plurality of golden fingers being located farther away from the plugging end than the first row of golden fingers;
each golden finger in the first row of golden fingers has a first end proximate to the plugging end and a second end opposite to the first end, the first row of golden fingers includes a grounded golden finger, a power signal transmitting golden finger, and a communication signal transmitting golden finger, the grounded golden finger is longer than the power signal transmitting golden finger or the communication signal transmitting golden finger, the first end of the grounded golden finger in the first row of golden fingers extends farther toward the plugging end than the first end of the power signal transmitting golden finger or the first end of the communication signal transmitting golden finger, the second end of the grounded golden finger extends farther away from the plugging end than the second end of the power signal transmitting golden finger, and the second end of the power signal transmitting golden finger extends farther away from the plugging end than the second end of the communication signal transmitting golden finger; and
each golden finger in the second row of golden fingers has a third end proximate to the first row of golden fingers and a fourth end opposite to the third end, the second row of golden fingers includes a grounded golden finger and one or more non-grounded golden fingers, the grounded golden finger in the second row is longer than the non-grounded golden fingers, and the third end of the grounded golden finger in the second row of golden fingers extends farther toward the plugging end than the third end of the non-grounded golden fingers.
