    (54) Electrical fuses


    (57) A miniature electrical fuse has electrical lead wires (8) to permit the fuse to be connected into a circuit without use of a fuse holder. Wires (8) are resistance welded to electrically conductive end caps (4) closing off the end of a non-conductive tubular housing (3) containing a fusible element (1). Element (1) is connected to the caps (4) by solder joints (7) and caps (4) are connected to housing (3) by solder joints (6). The solder is a lead/tin alloy of high melting point. The end walls of the caps (4) are comparatively thick in relation to their side walls in the range 1.3 to 1 and 2.1 to 1.
