Assembly of electrical components with substrates

Claim 1

An assembly comprising: (a) a substrate having a mounting hole threthrough; and (b) an electrical component mounted on the substrate; the component having a body portion and at least one lead of malleable conductive metal having a cylindrical shank portion extending from the body portion into and at least partway through the hole with a radial clearance from the wall of the hole less than the radius of such shank portion, the lead moreover having an arrowhead-shaped tip formed at the end thereof and integrally joined to said shank portion and positioned on the opposite side of the substrate from the component body for mechanically fastening the lead and component to the substrate, such tip being constituted of solid metal over the full extent of the dimensions occupied by such tip, the tip having barbs disposed rearward of the end of the tip, said barbs being characterized by respective backward facing points at the transversely outer extremities of said tip, and by respective surfaces extending from such points to said shank portion so as to be engageable with said opposite side of said substrate without a significant wedging effect on the side of said hole, the width between the points of such barbs being greater than the corresponding distance across the hole by an amount which is small enough to permit said tip to have been manually forced forward through said hole but which is large enough to produce a positive lock between such barbs and such substrate.
