Patent ID: 8808036

Claim:
An electrical connector having: a circuit comprising: a first side; a second side; a first differential channel located between the first side and the second side and comprising a first positive differential trace and a first negative differential trace for transmitting a first differential signal; and a second differential channel located between the first side and the second side comprising a second positive differential trace and a second negative differential trace for transmitting a second differential signal; and a plurality of mating contacts connected to the second side and numbered from one to eight in sequence along a transverse direction, thus comprising a first contact connected to the first positive differential trace, a second contact connected to the first negative differential trace, a third contact connected to the second positive differential trace, and a sixth contact connected to the second negative differential trace, the first contact, the second contact, the third second, and the sixth contact are arranged one by one; wherein a distance between the third contact and the sixth contact is greater than a distance between the first contact and the second contact; wherein a capacitor is connected between the second positive differential trace and the second negative differential trace to make an impedance of the second differential channel match with an impedance of the first differential channel.
