Claim 0:
1. A signal transmitting method, comprising:
transmitting a power signal through a power signal transmitting golden finger of the edge connector, the edge connector comprising a grounded golden finger coupled to a ground;
transmitting a communication signal through a communication signal transmitting golden finger of the edge connector;
wherein the edge connector further comprises:
a base board having one edge as a plugging end of the edge connector;
a first row of golden fingers adjacent to the plugging end including a first plurality of golden fingers disposed in parallel and isolated from each other on the base board; and
a second row of golden fingers including a second plurality of golden fingers disposed in parallel and isolated from each other on the base board farther away from the plugging end than the first row of golden fingers;
wherein 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 the grounded golden finger, the power signal transmitting golden finger, and the 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, and the first end of the power signal transmitting golden finger extends farther toward the plugging end than 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.
