ABSTRACT:
A fuse assembly comprises a fuse unit and housing therefor made of insulating material and having an initially fully opened side through which said plug-in fuse unit was inserted into said housing. The fuse unit has a pair of spaced, parallel, confronting terminals with portions exposed to the exterior of said housing through spaced openings in the initially fully open side of the housing. A fuse link interconnects other portions of said terminals, the fuse link being positioned to pass by an initially uncovered portion of the initially fully open side of the housing as the fuse unit is inserted into the same. The housing has a closure flap which initially has a position exposing said portion of the initially fully open side of the housing so that the fuse link can pass into the housing therethrough. The flap is folded to cover this open housing portion when the fuse link passes into the housing. A shoulder on at least one of the spaced terminals abuts the folded closure flap when the fuse unit is fully inserted into the housing, which is then anchored to the terminals of the fuse unit.
