  • Patent number: 11942300
    Abstract: A fuse shield features a cylindrical body, a first cap cover, a second cap cover, and a stop region. The cylindrical body is adapted to be placed over and partially surround a cylindrical fuse. The cylindrical body is sandwiched between the first and second cap covers. The stop region is located on an edge of the first cap cover to limit rotation of the cylindrical fuse to a first degree in one direction on a flat surface.

  • Patent number: 11923162
    Abstract: A fuse includes a stack, a flattened wire, and a terminal. The stack has multiple layers arranged to form steps. The stack has an upper stack with layers of a first size and a lower stack with layers of a second, larger size. The flattened wire is located between the upper stack and the lower stack. The terminal is connected to the flattened wire and includes multiple surfaces to cover the steps at one end of the stack.
