Electrical connector with improved terminals

An electrical connector comprising:

• an insulating housing having an upper face and a lower face, and a receiving passage and a retaining slot communicating with the receiving passage;
• and
• two identical metal pieces each comprising a blade retaining portion, an elastic arm and an elastic connecting portion extending from opposite edges of the retaining portion, and a contacting portion extending from the elastic arm;
• wherein the two metal pieces are inserted into the insulating housing from the upper face and the lower face respectively, the blade retaining portions are retained in the retaining slot, and the elastic connecting portion of one metal piece are mechanically and electrically connecting with the blade retaining portion of another metal piece so as to define a conductive terminal.

An electrical connector comprising:

• an insulating housing having an upper face and a lower face, and a plurality of receiving passages and retaining slots commuting with corresponding receiving passages;
• and
• a plurality of conductive terminals received in corresponding receiving passages;
• wherein each of the conductive terminals comprises an upper piece and a lower piece, the upper piece comprises an upper retaining portion retained in the retaining slot, an upper elastic arm and an upper connecting portion extending from opposite edges of the upper retaining portion, and an upper contacting portion extending from the upper elastic arm and located above the upper face, the lower piece comprises a lower retaining portion retained in the retaining slot and below the upper retaining portion, a lower elastic arm and a lower connecting portion extending from opposite edges of the lower retaining portion, and a lower contacting portion extending from the lower elastic arm and located below the lower face, the lower connecting portions are of a wave shape and the upper connecting portions are of a blade shape, the lower connecting portions mechanically and electrically connect with corresponding lower connecting portions respectively.
