Abstract
A boardlock for securely connecting an electrical device or connector to a printed circuit board without requiring post-soldering thereof, is shown comprising a pair of rigid arms joined at the lower end by a thinner bridge section. The boardlock is a flat unitary edge-stamped sheet metal part that is insertable through a hole of a printed circuit board such that the bridge portion extends below the printed circuit board and whereby outer portions thereof, extend outwardly of the hole for provisionally holding the boardlock to the printed circuit board. A die comprising an elongate slot of slightly greater thickness than the boardlock, can be engaged against the bridge portion for permanent plastic deformation thereof. The die has a convex bottomed surface in order to arc the deformed bridge portion towards the printed circuit board in order to enhance the mechanical resistance of the boardlock with respect to an upwards pulling force thereon.
