Disc fuse
First Claim
1. A disc fuse comprising:
- an electrically insulating substrate having a via formed therethrough extending between a first surface and a second surface of the electrically insulating substrate;
an electrically conductive first terminal disposed on the first surface of the electrically insulating substrate; and
an electrically conductive second terminal disposed on the second surface of the electrically insulating substrate, the second terminal including an outer portion having an inner edge defining a through-hole in the second terminal, the second terminal further including a fuse portion extending from the inner edge, the fuse portion comprising a fusible element terminating in a contact pad;
wherein the electrically insulating substrate provides an electrically insulating barrier between the first terminal and the second terminal and wherein the via provides an electrical connection between the first terminal and the contact pad wherein the second terminal is annular and wherein the fusible element has a curvilinear shape that extends along, and is spaced radially apart from, the inner edge of the outer portion.

10. A disc fuse comprising:
-
an annular, electrically insulating substrate having a via formed therethrough extending between a first surface and a second surface of the electrically insulating substrate; an annular, electrically conductive first terminal disposed on the first surface of the electrically insulating substrate, the first terminal coaxial with the electrically insulating substrate and having a diameter smaller than a diameter of the electrically insulating substrate; an electrically conductive second terminal disposed on the second surface of the electrically insulating substrate, the second terminal coaxial with the electrically insulating substrate and having a diameter smaller than the diameter of the electrically insulating substrate, the second terminal including an annular outer portion having an inner edge defining a through-hole in the second terminal, the second terminal further including a first and a second fuse portions extending from the inner edge, each of the first and second fuse portions being coplanar with the outer portion and comprising a fusible element terminating in a contact pad; and an annular, electrically insulating conformal coating disposed on the second terminal and covering the fusible elements of the first and second fuse portions; wherein the electrically insulating substrate provides an electrically insulating barrier between the first terminal and the second terminal and wherein the via provides an electrical connection between the first terminal and the contact pad.
