Abstract
An electrical contact pin for mounting in a printed circuit board. The pin has an H-shaped contact portion cross-section which is mounted in the hole by compliant press-fit action. The H-shaped cross-section comprises four compliant pins and a crossbar. The floor of the crossbar is V-shaped and the transition between the pins and floor is rounded. The height and thickness of the fins on each side of the V-shaped floor are substantially the same, thereby minimizing or eliminating rotation of the pin during insertion into the hole.
Claims3
An electrical pin for mounting in a hole of an electrical component such as a printed circuit board, said pin comprising a longitudinal contact section which interacts with the hole when inserted therein, said contact section being of generally H-shape in cross-section formed by four projecting fins extending generally parallel to the longitudinal axis of the pin and interconnected by a central crossbar along the length of the contact section, said fins and crossbar defining two longitudinal recesses disposed on both sides of the crossbar, each longitudinal recess having a V-shaped floor along said crossbar with the V-shape extending parallel to the longitudinal axis of the pin, the fins on both sides of each longitudinal recess being of the same height and thickness and the transition from the V-shaped floor to the pins on both sides of each recess being rounded.
