Electronic connector with fool-proof mechanism

An electronic connector with fool-proof mechanism comprising:

• an insulating body receiving a plurality of terminals, a welding pin formed at a back of each of the terminals, a first block projected from a bottom side of the insulating body and a plurality of second blocks projected from a top side of the insulating body;
• and
• a shielded body enclosing the insulating body and providing at least one first mated hole in a bottom side of the sided body corresponding to the first block of the insulating body and a plurality of second mated holes in a top side of the shielded body corresponding to the second blocks of the insulating body, the first and second mated holes respectively engaging with the first and the second blocks, said shielded body including a plurality of fixed pins with enlarged distal ends that are projected from the shielded body for insertion into corresponding openings in a circuit board.
