ABSTRACT:
An electrical connector for mechanically and electrically connecting a mother printed circuit board and a removable daughter printed circuit board of the card edge connection type. The connector has a housing with a slot for receiving an edge of the daughter board and two rows of contact chambers for receiving and holding individual contacts therein. The connector also comprises a plurality of a first type of contact having a contact area formed from a bulging bight having a coined contact surface, the curve of the bight and the curve of the crown producing a compound radii. The first type of contact also has a relatively straight angled section above the bight for initially contacting a leading edge of the daughter board with a relatively smooth transition between the angled section and the bulging bight to wedge the contacts outward from the housing slot without substantial risk of damaging the contacts, and the bulging bight allowing only the compound radii surface of the contact to contact the daughter board at an inserted home position.
