Claims

[Scope of utility model registration request]

(1) In a fuse where both ends of the insulating cylinder are sealed with caps and an indicator line in which a fuse element and a fusing indicator fusible wire and a resistance wire are connected in series is stretched between both caps, a sleeve with a conductive bottom plate is attached to the cap on the fuse indicator side. A special feature of this fuse is that the spring and indicator rod are housed in the sleeve, and an insulating plate is attached to the outside of the sleeve.The fuse is characterized by the fact that the indicator rod is made to protrude by melting the fusible wire.

(2) The fuse according to claim 1 of the utility model registration, characterized in that the end face of the sleeve on the bottom plate side and the stepped part of the bottom plate face each other at right angles so that the surface pressure is uniform. .
