Abstract
A miniature electrical fuse designed for at least 60 volt circuit applications in printed circuit application features protection against housing explosion under fuse blowing conditions by means of arc barrier-forming shroud members formed by confronting rigid arc barrier walls of base and cover members between which end terminals of the fuse are sandwiched. The walls form arc barriers which closely confront or contact the fuse wire on all four sides thereof ahead of the points where the fuse wire ends are connected to the terminals. These points of connection are advantageously out of alignment with the rest of the fuse wire. The terminals preferably extend from the confronting ends of the base and cover members where projections from the cover bearing on the terminals secure the terminals in place and seal the openings thereat.
