Abstract
A fusible element for an electrical fuse comprising a generally flat, strip-shaped body having a generally uniform cross-section; a constricted area formed in the body has a cross-section less than the cross-section of the body; an indentation formed in the body at least bordering on the constricted area; a solder coating disposed within the indentation; and a first solder stop coating on a first surface of the body that is disposed adjacent the solder coating to prevent migration of the coating along the surface.
Claims18
A fusible element for an electrical fuse, comprised of:
- a generally flat, strip-shaped body having a generally uniform cross-section;
- a constricted area formed in said body, said constricted area having a cross-section less than the cross-section of said body;
- an indentation formed in said body, said indentation in said body at least bordering on the constricted area;
- a cadmium-free and lead-free solder coating disposed within said indentation;
- and
- a first solder stop coating on a first surface of said body, said first solder stop coating disposed adjacent said solder coating to prevent migration of said coating along said first surface.
A fusible element for an electrical fuse, comprised of:
- a generally flat, strip-shaped body having a generally uniform cross-section;
- a row of generally aligned, spaced apart apertures extending generally transverse to the longitudinal axis of said body, said apertures defining a plurality of constricted areas between adjacent apertures;
- a groove extending across said body generally parallel to said row, at least a portion of said groove bordering on said constricted areas defined by said apertures;
- a cadmium-free and lead-free solder coating disposed within said groove;
- and
- a first solder stop coating on a first surface of said body, said first solder stop coating disposed adjacent said solder coating to prevent migration of said solder coating along said surface.
An electrical fuse, comprised of:
- a casing;
- and
- a fusible element within said casing, said fusible element comprising:
- a generally flat, strip-shaped body having a generally uniform cross-section;
- a row of generally aligned, spaced apart apertures extending generally transverse to the longitudinal axis of said body, said apertures defining a plurality of constricted areas between adjacent apertures;
- a groove extending across said body generally parallel to said row, at least a portion of said groove bordering on said constricted areas defined by said apertures;
- a cadmium-free and lead-free solder coating disposed within said groove;
- and
- a first strip of a solder stop coating disposed on a first surface of said body, said first strip of solder stop coating disposed to one side of said solder coating and bordering said solder coating at the narrowest point of said constricted areas.
