Press-fit pin, connection structure including the press-fit pin, and electronic device including the press-fit pin

摘要

A tip end and a base end therebetween define an opening located between a first conductive portion and a second conductive portion. The opening includes a pair of first linear portions, a pair of second linear portions, and a pair of third linear portions, which are located between the first conductive portion and the second conductive portion. The pair of first linear portions is in straight liner shapes and distant from both the tip end and the base end. The second linear portions are in straight liner shapes and located on the side of the tip end to have therebetween a distance decreasing toward the tip end. The third linear portions are in straight liner shapes and located on the side of the base end to have therebetween a distance decreasing toward the base end.
