Abstract
A new and improved fusible link having opposite ends. The fusible link comprises two pieces each having opposite ends. One of the opposite ends of each piece defines the opposite ends of the link. The other end of said pieces overlap each other and have a eutectic solder therebetween. Means is provided adjacent the other end of the pieces to strengthen the link in tension between the opposite ends when said solder is in shear and to reduce creep. Means is also provided adjacent the other ends of the pieces to separate the pieces and break the linkage upon the eutectic solder reaching the eutectic temperature. The new and improved fusible link in a specific embodiment utilizes a crimp and crimp sliding surfaces to prevent creep at temperatures lower than the eutectic temperature for providing separation of the link upon the solder being heated to a eutectic temperature.
