Fuse, including at least one fuse blade, formed in a sheet having two opposite main faces extending along a longitudinal axis of the fuse blade, each fuse blade comprising a portion having a reduced section defining a plane transverse to the fuse blade. The fuse also includes arc guards made of a preformed elastic material and associated in pairs, the arc guards of the same pair being each located opposite one another on a respective main face of the same fuse blade. For at least a first pair of arc guards, a layer of adhesive is interposed between the fuse blade and an internal face of each arc guard of this pair, the internal face being oriented towards one of the main faces of the fuse blade, so as to fix each arc guard on the fuse blade.

Fuse and associated manufacturing process

Fuse, comprising at least one fuse blade in which is formed a reduced section (A) defining a plane (P) transverse to the fuse blade. The fuse also comprises arc guards, which are made of an elastic material and which are associated in pairs, the arc guards of the same pair being each disposed opposite one another on one respective main side of the same fuse blade. Each arc guard comprises an internal face, oriented towards the fuse blade, a front face, oriented towards the reduced section, and a rear face, oriented away from the reduced section. At least one perforation is made in the fuse blade in the vicinity of the reduced section, each perforation being at least partially closed by the internal faces of the two arc guards of the same pair, each perforation leaving a cavity between the two arc guards of the same pair.
