<p>An electrical cartridge fuselink comprises a fusible element (3); an insulating barrel (1) having said fusible element disposed therein; end caps (8) mounted on either end of said barrel, and each being electrically connected to an associated end portion of said fusible means; and first and second centering means (2) being rigidly secured within said barrel at its opposite ends, each of said centering means having at least one centering bore for receiving an associated end portion of said fusible element; said end portion being electrically connected to the inner surface of the associated end cap (8). It is a general object to provide an improved structure of a cartridge fuselink of the above type, thereby offering the possibility to mass-produce such fuselinks with a cost-effective and reliable, fully automated manufacturing/assembly process. An electrical cartridge fuselink of this invention is characterized thereby that each one of said centering means (2) comprises a disk shaped support means having at least one bush (4) of electrically conductive material extending therethrough, said bush (4) defining a centering bore (5); said disk shaped support means being circumferentially shaped and dimensioned respectively for securing it within its associated end of said barrel (1). The electrical contact resistance between the ends of a fusible element and its associated end caps is well defined and can be made extremely low.</p> |
