Abstract: An electrical power connector includes an electrically insulative housing defining multiple front mating portions, multiple rear partition plates, an accommodation chamber between each two adjacent partition plates corresponding to one respective mating portion, a mating chamber in each mating portion and mounting holes on opposing top and bottom sides of the mating portions, pairs of conducting terminals respectively mounted in the accommodation chambers of the electrically insulative housing, and a heat dissipation mechanism including a plurality of thermal conductive metal plates fastened to the mounting holes of the electrically insulative housing with respective mounting lugs thereof and covered on the mating portions of the electrically insulative housing and for quick dissipation of heat.

Abstract: An electrical power connector includes an electrically insulative housing defining multiple front mating portions, a mating chamber in each mating portion for receiving one respective connection portion of a mating circuit board and two guide grooves in the mating chamber for guiding the respective connection portion of the mating circuit board into position, and pairs of conducting terminals respectively mounted in the mating chambers of the electrically insulative housing. Subject to the guiding of the guide grooves, the connection portions of the mating circuit board are kept in positive contact with respective front mating end portions of the conducting terminals to let the conducting terminals bear pressure evenly so that the operating conducting terminal impedance and temperature can be minimized, improving the reproducibility and reliability of the connector at the end of the circuit board and assuring a high level of power or signal transmission efficiency and safety.
