Press-fit electrical terminals
TLDR
In this article, the authors propose to use a pair of corrugated-faced dies into opposed anvil members to reduce longitudinal movement of material during swaging and improve dimensional tolerances.Abstract:
Press-fit electrical terminals such as press-fit pins for insertion into plated through holes of circuit boards. Such pins have a generally H-shaped press-fit zone formed by a central web 2 indented with a series of transverse corrugations 4 interconnecting four perpendicularly extending compliant fins 10, 10', 12,12'. Preferably the terminals are formed by stamping from sheet material with a plurality of such pins remaining interconnected to a carrier strip until after mass insertion into plated through holes. Stamping with a pair of corrugated-faced dies into opposed anvil members reduces longitudinal movement of material during swaging and improves dimensional tolerances. The corrugations on the central web reduce flexing of the pin after installation in the plated through hole. Preferably, the terminals include a slug of solder held on at least a portion of each of the opposed faces of the central web.read more
