Electrical connector with a soldering portion of a half-ball shaped

摘要

An electrical connector includes an insulative housing and a plurality of contacts assembled in the insulative housing. The insulative housing defines a mating face and a mounting face opposite to the mating face. A plurality of receiving passageways are extending through the mating face and the mounting face to form a first opening and a second opening. The contacts are assembled in the receiving passageways from the second opening. Each contact defines a base portion of a plate shaped retained in the second opening by a pair of barbs at two opposite first and second sides of the base portion and a pair of elastic arms extending from two opposite third and fourth sides of the base portion to the receiving passageway. The base portion protrudes a soldering portion of a half-ball shaped from an inside face facing the first opening to an outside face opposite to the inside face.
