Abstract
This specification discloses a terminal and a pigtail wire combination for holding small fuses, made up of a single piece of wire. The wire may be considered as having a first part and a second part integrally connected to the first part. The first part is wound to form a tightly wound hollow cylindrical coil having a plurality of turns disposed in engagement with each other. The second straight part of the wire is tangent to the last turn on one end of the coil and extends across the coil parallel to the diameter of the coil and terminates at a substantial distance from the coil. A pigtail wire can be soldered to the terminal and a fuse can be inserted in the coil. A pair of these terminals can be spaced from each other and both soldered to pigtail wires to support both ends of a suitable fuse. In the case of the fuse, the internal diameter of the cylinder formed by the wire is slightly smaller than the external diameter of the fuse terminals.
