Electrical connector

Claim 1

An electrical connector comprising: a housing including a pair of elongate side walls and a mating board disposed between the side walls, the elongate side walls and the mating board together defining an upper and lower receiving spaces respectively opposed to a top surface and a bottom surface of the housing, a plurality of ribs laterally extending from opposite inner surfaces of the side walls toward the mating board thereby increasing the rigidity of the side walls, the mating board forming a plurality of passageways in opposite surfaces thereof facing the side walls; and a plurality of contacts received in the housing, each contact including: a mating portion; a fixing portion extending from the mating portion and securely received in a corresponding passageway of the mating board; a slanted portion angularly extending downward from the fixing portion into the lower receiving space to prevent molten solder from wicking upward therealong; and a soldering portion extending from the slanted portion to solder to a circuit board, wherein the lower receiving space defines a recess for receiving the slanted portion of each contact therein; wherein the slanted portion of each contact is slantwise disposed between the fixing portion and the soldering portion; wherein the fixing portion is distanced a vertical height from the soldering portion; wherein the fixing portion forms a plurality of fixing protrusions on opposite edges thereof for securely engaging with a corresponding passageway; wherein each side wall forms a plurality of lateral slots in a bottom edge thereof, and wherein the soldering portions extend through the slots of the side walls to be secured therein.
