SPRING FOR FIXATION AND GROUNDING CONTACT OF A PRINTED CIRCUIT BOARD

摘要

Metal sheet spring for PCB fixation comprising a central embossed part connected by a plurality of die-cut arms to a peripheral part surrounding the central embossed part; wherein the central embossed part, the die-cut arms and the peripheral part are of the same metal sheet; wherein each of the die-cut arms comprises three sections, a first radial section connected to the central embossed part and connected to a second arc-shaped section which is connected to a third radial section which is connected to the peripheral part. The die-cut arms may be deformed such as to displace the central embossed part further in the direction of the embossment of said central embossed part, in particular such as to obtain a spring having an elastic force against the displacement of the embossed part. The metal sheet spring may also be an electrical contact of the PCB with the metal sheet.
