Electrical connector with fastening member fastened to power contact

A power connector comprising:

• an insulative housing defining a plurality of passageways;
• a plurality of U-shaped power contacts received in the passageways of the insulative housing, each power contact comprises a pair of contacting portions and a fastening portion essentially perpendicular to the contacting portions, each fastening portion has a through hole defined thereon;
• a locking piece defining a first side, a second side opposite to the first side and a plurality of mounting holes penetrating through the first side and the second side;
• and
• a plurality of fastening members assembled to the locking piece from the first side to the second side, each fastening member comprising a head resisting against the first side and a screw portion inserting through the mounting hole;
• wherein
• the screw portions of the fastening members further extend through the through holes of the power contacts and ultimately fixed to the fastening portions of the power contacts.

An electrical connector comprising:

• an insulative housing extending along a longitudinal direction, the insulative housing has a mating surface defined thereon, a mounting surface defined opposite to the mating surface and a passageway penetrating through the mating surface, where the mounting surface and the passageway extend along a transverse direction perpendicular to the longitudinal direction;
• a power contact received in the passageway of the insulative housing, the power contact comprises a pair of contacting portions and a connecting portion connecting the pair of contacting portions, the pair of contacting portions is essentially parallel to each other where a spacing is defined therebetween, the connecting portion comprises a fastening portion which is essentially perpendicular to the pair of contacting portions;
• and
• a fastening member separately made from the power contact to fasten securely to the fastening portion;
• wherein the insulative housing comprises a pair of inner side walls with the passageway formed therebetween, at least one of the inner side walls comprises a block protruding into the passageway, the pair of contacting portions being essentially located adjacent to the inner side walls, the block engages with the corresponding contacting portion for not only holding the corresponding contacting portion but also forming a heat-dissipation gap between the corresponding contacting portion and the neighboring inner side wall.
