An electrical connector includes an insulating body having a base, and multiple upper row terminals and multiple lower row terminals fixed in the insulating body. Each terminal has a soldering portion respectively extending out of the base. The upper row terminals include at least one upper row signal terminal, and the lower row terminals include at least one lower row signal terminal. The soldering portion of the upper row signal terminal is in contact with the soldering portion of the lower row signal terminal. By means of contact between the soldering portions of the upper row and lower row signal terminals, a transmission signal of the upper row signal terminal and a transmission signal of the lower row signal terminal are directly combined, and the signals do not need to be combined by other means. The transmission current is larger due to more conducted parts in the electrical connector.
