Abstract
A chip-type micro-fuse including a fusible element, a hollow body made of heat-resistant and insulative materials having at lesat two recesses which are respectively formed on an outer peripheral surface thereof, near the ends thereof and two end caps adapted to respectively cover the ends of the body for electrically connecting the body with external circuits. The end portions of the fusible element are respectively connected at the recesses to the end portions of the body. Further, the recess defined near one end portion of the body is positioned diagonally spaced with respect to another recess defined near the other end of the body. Thus, the fusible element is diagonally stretched between the ends of the body across the inner space of the body. When assembled, the end portions of the fusible element are respectively drawn out from the interior of the fuse without damaging the fusible element and connected at the recesses to the body. Furthermore, the end portions of the body are respectively fitted into the corresponding end caps such that the end portions of the fusible element are firmly held between the outer peripheral surface of the body and the inner walls of the end caps, respectively. Thus, this highly reliable chip-type micro-fuse can readily be made simply by inserting the end portions of the body into the end caps by the use of a press.
