Abstract (en)
[origin: EP3637451A1] Disclosed is a fuse device with a micro-powered switch comprising a micro-powered switch (2), a fuse device interlocking mechanism (5), a fuse wire striker pin assembly (6) and a connecting rod (7), wherein the fuse wire striker pin assembly (6) comprises a main shaft (601), striker pin pieces (602) and trigger pieces (603); the striker pin pieces (602) and the trigger pieces (603) are radially fixed on the main shaft (601), and can axially move around the main shaft (601); and when one or more fuse wires are not installed, or when one or more fuse wires have fused, the fuse device interlocking mechanism (5) cooperates with the fuse wire striker pin assembly (6) and drives the connecting rod (7) to trigger the micro-powered switch (2), whereby the switch device cannot close. The fuse device with a micro-powered switch has a simpler structure, effectively reducing production costs, and the modularised assembly saves on assembly time.
