Solderless surface mount fuse
First Claim
Patent Images
1. A surface mount fuse comprising:
- an insulative body;
first and second conductive end caps attached to the insulative body, each end cap defining an aperture that extends through a wall of the end cap; and
a fuse element having a horizontal section extending through the insulative body and the apertures, the fuse element further including first bent sections connected to opposite ends of the horizontal section, the first bent sections extending from the apertures along an outer surface of the first and second conductive end caps to a bottom surface of the first and second conductive end caps, the fuse element further including second bent sections connected to the first bent sections, the second bent sections being parallel to the horizontal section and configured to attach the fuse element to pads on a printed circuit board, wherein the fuse element is secured in the insulative body and the first and second conductive end caps are secured to the insulative body by the first bent sections.

Abstract
A surface mount fuse in one embodiment includes an insulative body, first and second conductive and caps attached to the insulative body, each end cap defining an aperture, and a fuse element extending (i) through the insulative body and the apertures and (ii) along outside surfaces of the first and second conductive end caps in such a way that solder used to attach the first and second conductive end caps to an external medium also fastens the fuse element to the first and second end caps.

6. A method of manufacturing a surface mount fuse comprising:
-
attaching first and second end caps to an insulative body, each of said first and second end caps defining an aperture that extends through a wall of the first and second end caps; inserting a fuse element into the insulative body such that portions of the fuse element extend through the apertures, the portion of the fuse element in the insulative body being disposed in a first plane; bending the portions of the fuse element that extend out of the apertures at a point near an outer surface of the first and second end caps to form first bent sections of the fuse element that extend along an outer surface of the first and second end caps; and bending portions of the first bent sections of the fuse element at a point near a bottom surface of the first and second end caps to form second bent sections of the fuse element that extend in the first plane parallel to the portion of the fuse element in the insulative body, the second bent sections configured to attach the fuse element to pads on a printed circuit board, wherein the fuse element is secured in the insulative body and the first and second end caps are secured to the insulative body by the first bent sections. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
