Electrical connector

A power connector mounting on a printed circuit board (PCB), comprising:

• an insulating housing extending along a transversal direction and defining a plurality of passageways extending therethrough along a front-to-back direction, said insulating housing having a top wall, an opposite bottom wall, and a pair of side walls connecting said top wall and said bottom wall, said insulating housing providing a beam in each of said plurality of passageways;
• and
• a plurality of pairs of flat power contacts received in corresponding passageways, each power contact having a main portion, a pair of contacting fingers extending from a forward edge of said main portion and a plurality of distal tails extending downwards from a bottom edge of said main portion, said pair of contacting fingers defining a groove therebetween, said groove engaging with said beam in corresponding passageway of said insulating housing so as to facilitate said contact being secured in said passageway with respect to said insulating housing;
• wherein said bottom wall of said insulating housing forms a U-shaped protrusion;
• wherein said main portions of said pair of power contacts are received in said U-shaped protrusion and opposite inside faces.
