Electrical connector and method for assembling the same

A method for assembling an electrical connector for electrically connecting a mating element and a circuit board, comprising the steps of:

• S1:
• providing an insulating body, wherein the insulating body comprises a plurality of receiving holes running therethrough and a plurality of resisting portions;
• S2:
• providing a plurality of terminals, and respectively assembling the terminals into the receiving holes, wherein one end of each of the terminals is provided with a soldering portion, and the soldering portion is provided with a soldering surface;
• S3:
• providing a plurality of solders, wherein each of the solders is located between corresponding one of the soldering portions and corresponding one of the resisting portions;
• S4:
• introducing an inert gas into the soldering surface;
• and
• S5:
• soldering the solder to the soldering surface by means of laser.
