An electrical connector includes an insulative housing with a plurality of passageways extending through opposite upper and lower surfaces of the housing. A plurality of electrical contacts are received within the corresponding passageways, respectively. Each contact includes a first main body and a second main body side by side arranged with each other with a bridge transversely linked therebetween. At least one of the first main body and the second main body includes a retaining barb for retaining contact in the passageway. Two soldering pads are formed on the corresponding bottom ends of the first main body and the second main body, respectively. The two soldering pads intimately confront each other either in a horizontal direction or in a vertical direction, and are joined together via a solder ball located under the two soldering pads.
