Fuse systems with serviceable connections
First Claim
Patent Images
1. A fuse system, comprising:
- a non-serviceable fuse;
a fuse terminal system having first and second terminals configured to selectively receive a serviceable fuse in parallel electrical connection to the non-serviceable fuse;
a housing at least partially enclosing the fuse terminal system and having at least one aperture to permit insertion of at least a portion of the serviceable fuse therethrough; and
an indicator being formed of a frangible material and extending across the at least one aperture;
wherein the indicator is irreversibly broken upon insertion of at least the portion of the serviceable fuse in to the at least one aperture therethrough.

Abstract
A fuse system has both a non-serviceable fuse and a fuse terminal system for selectively installing a serviceable fuse. When installed, the serviceable fuse provides a current flow path parallel to the non-serviceable fuse.

8. An electrical system, comprising:
-
an electrical circuit having at least one electrical component; a non-serviceable fuse in series electrical connection to the at least one component; a fuse terminal system having first and second terminals for selectively connecting a serviceable fuse in parallel electrical connection to the non-serviceable fuse; a housing at least partially enclosing the fuse terminal system and having at least one aperture to permit insertion of at least a portion of the serviceable fuse therethrough; and an indicator being formed of a frangible material and extending across the at least one aperture; wherein the indicator is irreversibly broken upon insertion of at least the portion of the serviceable fuse in to the at least one aperture therethrough. - View Dependent Claims (9, 10, 11)

12. A method of protecting an electrical component from an electrical current above a threshold level delivered by a power source, comprising:
-
connecting a non-serviceable fuse in a fuse terminal system between the power source and the electrical component; providing a first and second terminal in the fuse terminal system such that an electrical connection made by installation of a serviceable fuse between the first and second terminal creates a current flow path in parallel electrical connection to the non-serviceable fuse; providing a housing at least partially enclosing the fuse terminal system and having at least one aperture to permit insertion of at least a portion of the serviceable fuse therethrough; and providing an indicator being formed of a frangible material and extending across the at least one aperture, wherein installation of the serviceable fuse in to the first and second terminal through the at least one aperture irreversibly breaks the indicator upon insertion of at least the portion of the serviceable fuse in to the at least one aperture therethrough. - View Dependent Claims (13)
