A surface-mounted electrical connector, or other contact assembly, has an insulative housing which supports one end of contact pins, in two rows, one above the other. The other end of each contact pin is bent back beneath itself to extend along the lower surface of the housing in channels separated from one another by walls. The lower end of each pin has an enlarged spherical knob which contacts a respective conductive region on the surface of a printed circuit board. The roofs of the channels are rounded to receive the knobs, the height of the channels being substantially the same as the diameter of the knobs. The rear end of each contact pin is inclined downwardly, in its natural state, to project below the housing, so that it is urged resiliently into contact with the conductive region during mounting. A bolt helps secure the connector to the board. |
