Abstract: A connector comprises an insulative housing in which a plurality of passageways are defined. A plurality of contacts are received in the passageways. Each contact comprises an engagement plate loosely retained in the passageway, a positioning section connected to the engagement plate via a first flexible neck and mounted thereon a solder ball, a contacting section located above the positioning section and connected to the positioning section via a second flexible neck. When the solder ball is soldered on a printed circuit board and the housing and the contact is urged by an external electrical device, the housing is moved downward with respect to the engagement plate of the contact and the contacting section is pressed downward by the external electrical device, with the second flexible neck being deformed for providing a normal force facilitating the contacting section to abut against the external electrical device.
