An electrical connector adapted for electrically connecting with a circuit board includes an insulating housing, a plurality of first and second terminals, and a shielding shell enclosing the insulating housing together with the first and second terminals. The insulating housing includes a main body, and a base body assembled to the main body. The base body defines a plurality of first and second terminal grooves. The first and second terminals are respectively assembled to the first and second terminal grooves. Each first terminal has an inclined first connecting arm connected between a first fastening arm and a first soldering arm of the first terminal, and each second terminal has an inclined second connecting arm connected between the second fastening arm and the second soldering arm of the second terminal to effectively shorten straight lengths of the first terminal and the second terminal which are stretched straight.
