Spring strip for integrated thick film circuits - has locking springs at ends holding circuit and contact springs protected against excessive bending

摘要

A spring strip for integrated substrate thick film circuits consists of a plastic case with two guiding arms at its sides for the pluggable layer circuits, and of a base plate. Soldering tags are provided in the case next to each other, and locking springs are in the guiding arms. Soldering tags project downwards from the case, and soldering tags of adjacent contact springs are spaced along the side. A locking spring (6, 7) is provided at each end, at least one of which is pretensioned in a guiding arm (3). Contact springs are fixed and tensioned in the case (12) and protected against excessive bending.
