Thermal fuse for electronic telephone case in motor vehicle, has bridge for connecting parts of conductor paths and spanning opening that ruptures electrical contact between parts, where bridge is supported against parts of conductor paths

摘要

The fuse has a brazed bridge (14) connecting parts (10, 11) of conductor paths and spanning an opening (12) that ruptures electrical contact between the parts of the conductor paths. The bridge is supported against the parts of the conductor paths. Electronic components are assembled on the conductor paths that are etched on a printed circuit board (1). The width of the bridge is equal to that of parts of the conductor paths.
