ABSTRACT:
A six rib spider assembly for a fuse including a dielectic housing having end caps for supporting the spider assembly within the housing and a fusable ribbon helically wound on the spider assembly, the housing being filled with a granular dielectic material. The spider assembly including three mica plates each having a number of notches in their longitudinal edges to define support surfaces along each longitudinal edge for the fusable ribbon. These support surfaces on each longitudinal edge being offset from the support surfaces on the opposite longitudinal edge as well as from the support surfaces on each of the other mica plates. Each plate also including at least one longitudinal slot intermediate the longitudinal edges of the plate with one of the plates including a second slot, whereby the plates can be cross fitted into each other with the plates angularly related so that the support surfaces define a helical path for the fusable ribbon.
