Abstract

A fuse assembly has a one-piece molded housing providing alignment and guiding surfaces for insertion of a generally planar fuse assembly having side elements carrying a fuse link or diode therebetween. In one version the housing has an open bottom through which terminal blades formed as extensions of the side elements extend. A load-bearing structure prevents accidental fuse element assembly withdrawal from the housing. Polarized terminals for polarized devices such as diodes are provided by twisting one of the initially coplanar blades 90.degree.. The twisted joining portion between the so rotated terminal blade and its remaining structure inside the housing is disposed completely within the housing so as to provide a flush-mounting plug-in structure. A laterally extending non-current carrying extension of at least one of the terminal blades spans the major dimension of the housing interior at the bottom thereof to provide a measure of protection against entanglement of such devices when they are shipped or stored loosely.
