Abstract
To provide a novel cartridge fuse which can prevent the melted fuse member ends from being shorted together after the fuse member has been blown out and to firmly hold terminal members connected by a fuse member within a housing, the cartridge fuse comprises a fuse housing formed with an insulating partition extending therewithin to some extent to form a pair of terminal compartments; a pair of opposing terminal members each formed with a stay portion extending beyond the insulating partition and a contact portion housed within the terminal compartment, a fuse member connected to the stay portions of the opposing terminal members; and elastic members for applying a tension to fuse member in the longitudinal direction thereof.
