Abstract
An interconnection system that includes a daughter card and backplane electrical connectors mounted to printed circuit boards at connector footprints. The spring rate of beam-shaped contacts in the daughter card connector increases while mating with the backplane connector so that the retention force may be greater than the insertion force. Such a change in spring rate may be achieved by positioning the beam-shaped contacts adjacent a surface of a connector housing. That surface may include a projection that aligns with the beam-shaped contact. When the connectors are unmated, the beam-shaped contact may be spaced from the projection. As the connectors begin to mate, a central portion of the beam-shaped contact may be pressed against the projection, which has the effect of shortening the beam length and increasing its stiffness.
