Contact spring

摘要

A contact spring for securing a component having a flange-like edge to a substrate, for instance for securing a cooling screen or shield to a circuit board, includes an elongated profiled part that is generally U-shaped in cross section for surface-mounting on the substrate. A first leg of the U-shaped profiled part is substantially straight and extends continuously along the contact spring. The second leg of the U-shaped profiled part has tongues whose upper extremities are bent inwardly towards the bottom of the profiled part. Alternate tongues on the second leg are angled to form a fork-like contact with the first leg. The other tongues on the second leg are semicircular and extend approximately half way above the bottom of the profiled part.
