Abstract

A plug-in electrical fuse comprises a fusible wire (9) disposed within an insulating housing (1) and connected between the ends of two blade-like terminals (4) secured within and projecting from the housing. Fuses of this type are manufactured by forming a strip of terminal members from strip metal, each member comprising two spaced substantially-coplanar blade-like terminal portions interconnected at their leading ends (5) by an integral cross-bar portion, and each terminal member being integrally connected with each adjacent terminal member in the strip by an interconnecting bar of the metal strip. Fusible wire is secured to the terminal portions adjacent their rear ends to form a strip of terminal and wire assemblies, and this strip of assemblies is mounted in a strip of insulating housings with the fusible wires disposed within the housings and the leading ends of the terminal portions projecting therefrom. The interconnecting and cross-bar portions between adjacent assemblies and between the terminal portions of each assembly are then severed so as to separate the strip into individual fuses. The housings may be retained connected together in strip form and be separated only w…
