1. An electrical connector mounted to a printed circuit board (PCB) for mating with a complementary connector, comprising:
an insulating housing comprising a mating face confronting the complementary connector, a mounting face opposite to the mating face and a rear wall positioned between the mating face and the mounting face along a front-to-back direction, the insulating housing defining a plurality of contact-receiving passageways penetrating from the mating face to the rear wall and a plurality of heat dissipating slots communicating with the contact-receiving passageways; and
a plurality of conductive contacts respectively received in the contact-receiving passageways, each conductive contact comprising a contacting portion, a termination portion adapted for electrically connecting with the printed circuit board, and an intermediate portion connecting the contacting portion with the termination portion and retained on the rear wall;
wherein the insulating housing comprises a heat dissipating section defined between the mounting face and the rear wall, and wherein the heat dissipating section communicates with the heat dissipating slots to thereby define a heat dissipating path therebetween, the insulative housing has a top wall connecting the mating face and the rear wall, and a plurality of heat dissipating grooves are arranged on the top wall along a transverse direction, the heat dissipating grooves are communicated with an exterior along an up-to-down direction and the front-to-back direction;
wherein the conductive contact has a pair of retaining protrusions formed along two opposite side edges of the intermediate portion thereof and wherein the contact-receiving passageway defines a limitation means in an inside wall for retaining the conductive contact by engaging with the retaining protrusions.
