US Patent 11855391 High speed electrical connector with reduced crosstalk

An electrical connector comprising a terminal module, which comprises a ground terminal and a signal terminal disposed side by side with the ground terminal. The ground terminal comprises a first contacting part. The signal terminal comprises a second contacting part. An outer diameter of the first contacting part is greater than an outer diameter of the second contacting part. The contacting end of the ground terminal is wider than the contacting end of the signal terminal. By increasing the width of the contacting end of the ground terminal, the distance between the contacting end of the signal terminal and the contacting end of the adjacent ground terminal can be shortened. In this way, the return path for the signal terminal can be shorter, and more energy can be bound between the signal terminal and the ground terminal to avoid excessive interference from the surrounding magnetic field.
