Electrical connector with terminals bonded to housing

An electrical connector adapted for being soldered to a printed circuit board, comprising:

• an insulating housing defining a plurality of terminal grooves therein;
• and
• a plurality of electric terminals received in the corresponding terminal grooves of the insulating housing, each of the electric terminals having a welded portion extending outside from a rear of the insulating housing for being soldered to the printed circuit board, a substantially inversed funnel shaped injecting portion being formed at a middle portion of the welded portion with a diameter of an opening on one side of the welded portion being larger than a diameter of an opening on an opposing side thereof, wherein a liquid-state material is injected into the larger diameter opening of the injecting portion and then flows out from the smaller diameter opening of the injecting portion to spread to the welded portion and the insulating housing gradually for making the welded portion and the insulating housing being integrated together by the solidification thereof to leave a tail end of the welded portion being exposed outside.
