Abstract
A compliant electrical connector pin for press-fit connection to a plated hole in a circuit board is disclosed. A compliant section is provided on the pin to frictionally engage the hole walls, thereby retaining the pin within the hole. The compliant section includes two V-shaped troughs having flat bottom faces. These faces define a web which compresses when the compliant section is pressed into the hole. Barrier walls in the bottom of each trough normal to the flat bottom face guide the compression of the web and prevent the web from splitting or shearing. The sides of the trough define two flanges, the exterior of which contact the hole in the circuit board. The outer corners of the flanges are angled to match more closely the circular shape of the hole, thereby reducing hole damage from sharp corners on the compliant section and enabling the pin to fit smaller diameter holes.
