Abstract
Abstract A multi-pin electrical connector is adapted for surface mounting on a printed circuit board. The connector includes a header or housing having a plurality of pin-receiving through holes. A plurality of terminal pins are received in the holes of the header, with portions adapted for surface mounting on circuit traces on the printed circuit board. The terminal pins have spaced enlargements located on opposite sides of the header to retain the pins in the holes. The enlargements are spaced along the pins a distance greater than the thickness of the header about the holes whereby the pins can float in the holes to accommodate any non-uniform spacing between the header and the printed circuit board and ensure contact of the terminal pin portions with the circuit traces on the printed circuit board.
