ABSTRACT:
A solderless cartridge fuse comprises an open-ended insulating housing made of a relatively rigid, unyielding material. End caps close the open ends of the housing. Each end cap comprises an end wall confronting the adjacent housing end and a flexible yieldable side wall which, in its pre-formed state, has a lesser size than the periphery of the adjacent end of the housing so that there is a tight interference fit between the conductive end cap side wall and the housing periphery. A fuse element extends diagonally across the interior of the housing. Prior to application of the end caps to the housing ends during fuse assembly, the fuse wire ends are bent back around the housing ends so to be tightly sandwiched between the side walls of the end caps and the housing when the end caps are applied thereover.
