Electrical connector

An electrical connector for being mounted to a printed circuit board, the printed circuit board having a containing gap opened at one side thereof and defining a plurality of fastening holes arranged around the containing gap, the electrical connector being received in the containing gap, comprising:

• an insulating housing, the insulating housing having a base portion with two outer sides of rear ends thereof respectively extending outward and then extending forward beyond the base portion to form a fastening arm, a narrow slot being formed between the fastening arm and a corresponding side of the insulating housing;
• a plurality of terminals disposed in the insulating housing;
• and
• a shielding shell enclosing the insulating housing, and having two opposite side plates, a bottom portion of each side plate extending outward and then inclining upward to form a first soldering arm inserted into the corresponding fastening hole and then soldered together with the printed circuit board, a receiving space being formed between each of the side plates and the first soldering arm adjacent to the corresponding side plate, the fastening arms being snapped into the receiving spaces and abutting against the respective side plates and insides of the first soldering arms with rears of the side plates being clipped in the corresponding narrow slots.
