An electrical plug connector includes a metal shell, an insulation housing, upper-row elastic terminals, and lower-row elastic terminals. The metal shell defines a receiving cavity to receive the insulation housing. The insulation housing includes an upper member, a lower member, and a mating room between the upper member and the lower member. The upper-row elastic terminals are held on a lower surface of the upper member and include upper-row elastic contact segments extending toward the mating room for transmitting first signals. The lower-row elastic terminals are held on an upper surface of the lower member and include lower-row elastic contact segments extending toward the mating room for transmitting second signals.
