Solderless connector pin for electrical circuits

Abstract From the Canadian patent

A connector pin adapted to be inserted into a metallized bore in a conductive plate to form a solder-free mechanical and electrical connection between the pin and plate is fabricated, to provide an elongated deformable region adapted to engage the sides of the bore and consisting of two elongated beam members that are interconnected to one another by a cross member. The cross section of the resulting deformable region may be M-shaped or W-shaped. Upon insertion of the pin into the bore the, deformable region deforms elastically and in the case of a, small diameter bore, partially plastically to provide a good electrical and mechanical connection between the pin and plate.
