An electrical connector includes an elongated insulating housing defining a number of passageways and power terminals received in corresponding passageways. The passageways are arranged side by side along a longitudinal direction of the insulating housing. Each power terminal has a first terminal and a second terminal oppositely arranged beside the first terminal. The first terminal has a first contacting portion, a first fixing portion extending towards the second terminal, and a first connecting portion connecting the first contacting portion and the first fixing portion. The second terminal has a second contacting portion oppositely arranged beside the first contacting portion of the first terminal. A curved intermediate region is formed between the first connecting portion and the first contacting portion of the first terminal. A width of the first fixing portion is larger than a distance between the first contacting portion and the second contacting portion.
