Patent ID: 7477129

Claim:
A housing for a current limiting fuse that includes a metal fuse element and a non-conductive filler material, wherein the fuse element is configured to melt to create an open circuit when an applied current exceeds a threshold amount, the housing comprising: a first cylindrical member having an open end portion, and a second cylindrical member that includes an insulating closed end portion and an insulating open end portion that opens toward the first cylindrical member to form an open cylindrical cavity and that is configured to be attached to the open end portion of the first cylindrical member to close the housing; and a fastening member configured to prevent the open end portion of the first cylindrical member from separating from the open end portion of the second cylindrical member when the fuse element melts; wherein the insulating closed end portion is integrally formed with the insulating open end portion of the second cylindrical member; wherein at least one of the first cylindrical member and the second cylindrical member makes contact with the non-conductive filler material; and wherein the housing retains the non-conductive filler material inside of the current limiting fuse such that the metal fuse element makes contact with the non-conductive filler material.
