Abstract: A push-in rivet for being mounted on and interconnecting a connector and a circuit board. The rivet body includes a head portion, a plurality of spaced-apart flexible legs, and a shank portion which interconnects the head portion and the legs. The legs are flexible and are subsequently radially inwardly movable for passage through a hole formed in the board and radially outwardly movable after passage through the hole so as to interconnect the connector and the board. The method of riveting the connector to the board includes the steps of passing the rivet through a hole in the connector so that the head portion abuts a surface of the connector, drawing a mandrel through the bore so as to outwardly expand the legs, and passing the legs of the rivet through a hole in the board so as to radially inwardly compress the legs for passing through the hole in the board and subsequently radially outwardly expanding the legs so as to secure the board to the connector.
