Spring contact esp for printed circuits

摘要

The spring contact consists of a metal component and a rubber elastic shaped part of electrically conducting plastic and forms a connection with a defined electrical and HF impedance. The metal component is integrated into the circuit board as edge metallisation of a through hole in the conducting track structure or is soldered on and forms a holder for the elastic shaped part, pref. by shape locking. The elastic shaped part (8) exerts a spring effect by selection of a suitable elastomer and by structural measures, pref. a suitable cross-sectional shape.
