An edge connector adapted to accept a memory card therein, the memory card having two opposite side surface, each provided with a plurality of terminal contacts, the electrical connector comprising:

• an insulated body formed with a reception chamber;
• a plurality of first terminals mounted on said insulated body, each having a fixing section extending into the reception chamber and a transmission section integrally formed with, bent relative to the fixing section and extending into said reception chamber, said transmission section being provided with a scratching corner;
• a plurality of second terminals mounted on said insulated body, each having a fixing section extending into said reception chamber and a transmission section integrally formed with, bent relative to the fixing section and extending into said reception chamber and cooperating with said transmission section of said first terminal to define a card slot therebetween, said scratching corner of said first terminal projecting into said card slot;
• wherein, forcibly insertion of the memory card into said card slot causes said scratching corner to scratch away of an oxidized layer, which is formed on the terminal contacts of the memory card, thereby enhancing electrical connection between the memory card and said first and second terminals.
