Abstract: An electrical connector comprising a terminal module and a housing. The terminal module comprises a plurality of terminals. The housing comprises an accommodating groove in which the terminal module is disposed. The accommodating groove comprises a first groove wall and a second groove wall opposite to the first groove wall. The terminal module is disposed between the first groove wall and the second groove wall. A wall surface of the first groove wall and a wall surface of the second groove wall are disposed close to a structural contour of the plurality of terminals.

In this way, the relative dielectric constant around the plurality of terminals would be increased to reduce the impedance.

Abstract: 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.
