Electrical connector

A stacked type connector for insertion of at least four mating electrical connectors, said connector comprising:

• an insulating housing having two spaced-apart side walls, which are formed integrally therebetween with at least two left and right plug seat units, each of said plug seat units having two upper and lower stacked plug seats, each of said plug seats being formed with a plurality of terminal receiving slots, said housing defining an insert direction, each of said side walls being formed with a retaining notch that extends in a direction opposite to said insert direction for detachable insertion of a circuit board therein, two spaced-apart retaining arms being formed between said two plug seat units and extending oppositely of said insert direction, said retaining arms clamping fixedly said circuit board;
• and
• a plurality of terminals received respectively in said terminal receiving slots, each of said terminals interferentially engaging an inner wall of a corresponding one of said terminal receiving slots, and having a contact end received in the corresponding one of said terminal receiving slots, and a soldering end projecting out of the corresponding one of said terminal receiving slots and connected electrically to said circuit board;
• wherein, when each of said plug seats permits detachable insertion for a mating electrical connector, said mating electrical connector is correspondingly and electrically connected to said terminals to establish an electrical connection with said circuit board.
