Abstract:
A subminiature time delay fuse device having at least one time delay fuse for receiving a power signal and providing an open circuit when the power signal is determined to be excessive, the improvement comprising:a housing having a plurality of vent holes formed therein, wherein the housing partially encloses the at least one time delay fuse, and wherein heat is dissipated through the plurality of vent holes, the housing comprising: a front cover with at least one open-air vent; and a back cover comprising: an end cap formed at a top end of the back cover; and notches formed on a bottom end of the back cover; and side vents defined by openings formed between the front cover and the back cover when the front cover and the back cover are assembled to form the housing; and two conductive terminals having an amount of metal sufficient to dissipate heat generated by the subminiature time delay fuse device, each of the conductive terminals having an upper end and a lower end, wherein the lower ends extend from the notches in the housing, and wherein the at least one time delay fuse is mounted to the upper ends within the housing, and wherein the at least one time delay fuse forms a fuse subassembly when mounted onto the upper ends of the conductive terminals and the fuse subassembly is aligned with the side vents.
