Abstract

An electrical connector having an insulative housing, a plurality of first terminals and a plurality of second terminals. The first terminals are disposed in the insulative housing. Each of the first terminals has a first contact portion, a first solder portion, and a first connection portion between the first contact portion and the first solder portion. The plurality of second terminals are also disposed in the insulative housing. Each of the second terminals has a second contact portion, a second solder portion, and a second connection portion between the second contact portion and the second solder portion. The first solder portions of the first terminals and the second solder portions of the second terminals are arranged in two rows in a lateral direction, respectively. The row of the first solder portions is separated from the row of the second solder portions by a predetermined distance in a longitudinal direction.
